Bottle valve Technical field:. The utility model relates to a kind of bottle valve that fire is visited bottle that is used for. Fire is visited device, and promptly fire is visited bottle, vessel valve is that bottle valve and fiery inserting tube that can discharge extinguishing agent or releasing tube etc.
With fiery inserting tube place near or above burning things which may cause a fire disaster most probable nidus, simultaneously, rely on and to survey along many sensing points of fiery inserting tube. Because fiery inserting tube or nozzle directly are arranged in the protected area, guarantee its reaction fast, accurately, extinguishing agent discharges in time, and the specific aim and the validity of fire extinguishing are stronger, can survey and put out the fire of incunabulum quickly and effectively, are a kind of early stage fire-fighting equipments.
This and conventional fixed formula gas extinguishing system wait until that the intensity of a fire is very big, and just the principle of putting out a fire at whole room or large space is compared and had the more timely and more effective characteristics of fire extinguishing. At present, bottle valve comprises valve body, T type piston, valve gap and ball valve etc. The utility model provides at above problem that a kind of exhaust gas circuit latus rectum is big, the extinguishing agent mass rate of emission is very fast, easy to use and Security bottle valve preferably.
The utility model overcomes the above problems used technological scheme: a kind of bottle valve with following structure is provided, it comprises secondary valve and main valve, described secondary valve and main valve comprise import, valve pocket and outlet, the import of described secondary valve is communicated with the valve pocket of main valve, described secondary valve outlet port is provided with ball valve, the outlet of described main valve is provided with connecting base, the one-way valve that described connecting base is provided with at least one air outlet joint and is communicated with ball valve.
Slidely connecting the cross section that valve pocket is divided into first chamber, second chamber and the 3rd chamber in the valve pocket of described secondary valve is the piston of T type, be provided with the intersection cross bore of lower end sealing in the described piston, described intersection cross bore is communicated with first chamber and the 3rd chamber; When described piston is in the limit inferior position, the import of secondary valve with the outlet between be not communicated with mutually.
Be provided with pressure-stabilizing spring between the lower surface of the big end of described piston and the chamber wall of second chamber. Slidely connect the cylinder-piston that the control main valve opens and closes in the valve pocket of described main valve, described cylinder-piston is provided with center hole.
Therefore the utlity model has that exhaust gas circuit latus rectum is big, the extinguishing agent mass rate of emission is very fast, easy to use and Security characteristics preferably. As improvement, the chamber wall of described secondary valve valve pocket is provided with and is used for through hole that second chamber is in communication with the outside, can make that then the air in second chamber can be discharged when T type cross section piston moved downward from through hole, so just can avoid the air in second chamber T type cross section piston to be produced a power that makes progress because of moving down of T type cross section piston is squeezed, thus the problem of the pressure when causing the piston pressure required in T type cross section greater than design to the limit inferior position.
As further improvement, the upper end of described secondary valve is provided with Decompression valves, described Decompression valves is communicated with first chamber, then at the pressure of secondary valve chamber during greater than predefined value, Decompression valves can be discharged a part with the gas in the chamber, make secondary valve chamber maintain in the normal range of pressure values, therefore Security of the present utility model is better.
As further improving again, the side of described main valve import is provided with the gas charging valve that is used to inflate, described gas charging valve is communicated with the import of main valve, and gas charging valve is provided with and is used to the bonnet that prevents that dust from entering, then after using, can also inflate gas cylinder by gas charging valve, and need not and will just can gas cylinder be inflated after the utility model unloading, it is simpler to make that the utility model uses; Bonnet can prevent that dust from entering gas charging valve simultaneously, also because of entering gas charging valve, dust cause molding of charge valve cores to close fully with regard to not occurring, thereby can avoid gas pressure in the gas cylinder to be reduced to the generation of the problem of inefficacy scope too early, so the stability during of the present utility model the use is better.
As further improving again, the sidewall of described main valve import is provided with step hole, be provided with safety installations in the described step hole, described safety installations comprises safety plug and is pressed on rupture disk on the step hole step surface by safety plug, be provided with the passage that is in communication with the outside in the described safety plug, then the gas pressure that goes out when the main valve import can bear greater than rupture disk pressure the time, rupture disk is crushed, this moment, the pressure of main valve inlet will release from the passage of safety plug, thereby the problem that can prevent that pressure in the gas cylinder is excessive and break further improves Security of the present utility model.
As shown in the figure: 1, main valve, 1. Below in conjunction with the drawings and specific embodiments, the utility model is described further:. As Fig. Slidely connecting the cross section that valve pocket is divided into first chamber 2.
Be provided with pressure-stabilizing spring 3 between the lower surface of described piston 4 big ends and the chamber wall of second chamber 2. The chamber wall of described secondary valve 2 valve pockets is provided with and is used for through hole 2. The upper end of described secondary valve 2 is provided with Decompression valves 5, and described Decompression valves 5 is communicated with first chamber 2.
The side of described main valve 1 import 1. Slidely connect the cylinder-piston 13 that control main valve 1 opens and closes in the valve pocket of described main valve 1, import 1.
Be provided with the ball 11 of smooth air in the described center hole The sidewall of described main valve 1 import 1. During use, at first the import 1. General ball valve 14 all is in open mode. When near the emergent using method the during breaking out of fire gas cylinder: at first ball valve 14 is closed; The end that ball valve 14 and fiery inserting tube between the one-way valve 7 are connected with one-way valve 7 is extracted subsequently, and should hold and aim at burning things which may cause a fire disaster; Opening ball valve 14 at last gets final product.
Above embodiment only is preferred embodiment of the present utility model; the utility model is not limited only to above embodiment and also allows other structural change; as: air outlet joint two, three, four and six or the like can be set as required; allly in the utility model rights to independence claimed range, change, all belong to the utility model protection domain.

Super Best Audio Friends. Read these "rules" AND introduce yourself before your first post. A healthy approach to understanding measurements Being true to what the artists intended.
Bottlehead Seduction Phono stage. My turntable will be arriving shortly, and i need to build a phono stage. Does anyone have the schematic on-hand? It's PTP wiring, of course.
You could stop now and live in personal audio bliss. Clearly, you are a DIY type person. Damn it, you own a soldering iron for a reason! The Crack is an affordable kit, so builders will inevitably want to tinker and further improve performance. Bottlehead supports creativity, but they strongly caution you to build and test the Crack in stock form first, before attempting any modifications. Doc B states.
