Abstract
The utility model provides a selector valve for gas fire-extinguishing system relating to a selector valve for fire-extinguishing system. The selector valve for gas fire-extinguishing system provided by the utility model comprises a valve body, a valve flap shaft, a cylinder body, a plunger, valve flap shaft end screws and a hand control valve. The valve flap shaft is arranged in a valve cavity, one end of the valve flap shaft is arranged at the outlet of the valve body, and the other end of the valve flap shaft is provided with a gas storage cavity between the valve body. The hand control valve is arranged on the top end of the valve body, the valve body inlet of the control valve is communicated with the valve body of the selector valve, and a pressing sleeve is arranged on the bottom of a valve core. The bottom of the plunger is connected with the top of the valve core. A spring is arranged on the valve core, and a deflector rod is connected with the plunger. When the valve gate is opened, the gas in the gas storage cavity is compressed to be discharged pressure through a damping hole to prevent the sealing ring of the valve body outlet flying off and the valve flap shaft and the valve body being deformed and damaged. When opening the manual operation urgently, the user can operate the deflector rod to make the hand control valve, the plunger, the valve core and the pressing sleeve opened, and then the gas enters into the air cylinder through the control valve from the inlet, pushing the plunger, opening the valve gate and making the manual operation labor saving, safe and reliable.

Background technique
Selector valve is widely used in the fire-fighting gas extinguishing system, is the visual plant of the long-range throughput direction of control fire-suppressant gas, generally is made up of valve body, flap axle and corresponding locking opening mechanism etc.When valve open, because the abrupt release of high-pressure medium because of there not being damping mechanism, causes the bump of related components to damage, when carrying out selector valve urgent manually opened, manually-operable had not only been required great effort but also inconvenience, and safe and reliable inadequately again, lack working life.Notice of authorization number provides a kind of pipeline selector valve for the patent of CN2632431Y, the pipeline selector valve is made of body and guiding valve, body forms by there being the radial pattern gusset to connect between the circular inside and outside cover of coaxial arrangement and the inside and outside cover, inside and outsidely put, last aperture and following aperture are arranged between the bottom, there are central diaphragm and middle aperture in the overcoat middle part, guiding valve is a dumbbell shape, and the middle-grade O RunddichtringO of guiding valve groove is provided with a penthouse and a circle negative pressure aperture that concaves.Notice of authorization number provides a kind of differential pressure type selector valve for the patent of CN2438880Y, starts interface, piston, main valve body, stopping device, secondary valve, the right side (air inlet) valve body, spring, electricity by a left side (giving vent to anger) valve body, gas and starts interface, seal ring, seal arrangement etc. and form.
Summary of the invention
The utility model aims to provide a kind of selector valve that is used for gas extinguishing system, when it not only can work as valve open, has pooling feature, prevents that component from being broken; And when the manual emergency of implementing selector valve was opened, the operation by to the hand control valve that is arranged at the valve body top utilized the air pressure of selecting fed sheet of a media in the valve pocket, opens it.
The utility model is provided with valve body, flap axle, seal ring, air storing cavity seal ring, cylinder body, piston, piston packing, flap axle head screw and hand control valve, valve body is provided with import and outlet, flap is located in the valve pocket of valve body, the one end is positioned at the outlet of valve body, be provided with air storing cavity between the other end and valve body, the top of flap axle and piston are spirally connected by flap axle head screw; Hand control valve is located at the top of valve body, hand control valve is provided with hand control valve body, spool, gland, gland seal ring, spring, bonnet, hand control valve piston, straight pin, driving lever, the import of hand control valve body is communicated with the selector valve valve body, gland is located at the bottom of spool, the bottom of hand control valve piston connects the top of spool, spring housing is located on the spool, driving lever is connected with piston by straight pin, the outlet of hand control valve valve body connects copper pipe by the flared fitting nut, copper pipe connects tee union, and a port of tee union connects the cylinder body of selector valve.
Can establish straight coupling on the cylinder body of selector valve.
Can establish arming pin on the hand control valve driving lever.
Compare with existing selector valve, owing in the valve pocket of valve body, be provided with air storing cavity, therefore when valve open, the gas storage intracavity gas is compressed through the damping hole pressure release, play buffer function, prevent flying off of valve outlet seal ring, collision deformation between flap axle and valve body and damage.In addition, owing to be provided with hand control valve, when implementing the emergency opening manually-operable of selector valve, can operate driving lever, hand control valve piston, spool, gland are opened, gas enters cylinder by import by hand control valve, promote piston, open valve, make manually-operable more laborsaving, safety and reliability.
