Abstract
The utility model provides a remotely-controlled cylinder valve. The remotely-controlled cylinder valve comprises a valve body, a valve element, a piston, a spring, a valve cap and a pressure gauge. The pressure gauge is fixed on the valve body through a pressure gauge connector and a locking nut. The valve element, the piston and the spring are positioned in an upper cavity formed by the valve body and the valve cap. A burst diaphragm is arranged at a position where a sealing plug of the upper end of the spring contacts with the valve cap. O-shaped sealing rings are arranged on the side wall where the valve body contacts with the piston and on the side wall where the valve body contacts with the valve element. A main sealing gasket is arranged between the piston and the valve element. A lower cavity formed by the valve body and the valve cap is communicated with a decompression cap. A burst diaphragm is arranged on a contact face of the decompression cap and the valve body. The decompression cap and the burst diaphragm are added on the side portion of the valve body, pressure in an air storage cylinder can be decompressed automatically when reaching a certain value, and the burst diaphragm at the upper end of the spring is not affected and broken, so that pressure in the air storage cylinder is kept at a safe level well.
Description
Technical field
The utility model belongs to long-range fire-fighting technique field, is specifically related to a kind of telecontrol bottle valve.
Background technique
In prior art, fire extinguishing is usually located at stuffy position with gas holder, and often long-term sun direct projection, easily causes gas holder superpressure, has potential safety hazard, once blast, consequence is hardly imaginable.Traditional fire extinguisher vessel valve is by puncturing the explosion diaphragm of spring upper end portion, thereby makes spring reset discharge extinguishing agent, and does not consider the potential safety hazard of gas holder when superpressure.
Summary of the invention
For above deficiency, the utility model provides a kind of telecontrol bottle valve, guarantees the Security of gas holder.
The technical solution of the utility model: telecontrol bottle valve, comprise valve body, spool, piston, spring, valve gap and pressure gauge, pressure gauge is fixed on valve body by GAUGE CONNECTOR, locking nut, wherein spool, piston, spring three are positioned at the inside of the upper chamber consisting of valve body and valve gap, the position that the sealing plug of spring upper end portion contacts with valve gap is provided with explosion diaphragm, on the sidewall contacting with piston at valve body, be provided with O RunddichtringO, on the sidewall contacting with spool at valve body, be provided with O RunddichtringO, between piston and spool, be provided with primary seal pad; The lower chambers consisting of valve body and valve gap communicates with pressure release cap, and the surface of contact of pressure release cap and valve body is provided with explosion diaphragm.
Valve body outside is provided with a room, and this room communicates with the upper chamber consisting of valve body and valve gap, gas is installed in the room in valve body outside and detects controller.
The beneficial effects of the utility model: the utility model is by increasing pressure release cap and explosion diaphragm in valve body side, make the pressure releasing pressure automatically when surpassing certain value in gas holder, and don't affect and miss brokenly the explosion diaphragm of spring upper end portion, well guaranteed that the pressure in gas holder maintains level of security; Gas outside valve body in room detects controller can accurately grasp the action situation of gas holder, and this information is accurately fed back to staff.
