Abstract
A gas automobile cylinder valve which improves the safety protection device is used for the safety protection when the gas automobile cylinder is opened or closed, and includes a valve body, an opening and closing assembly and a safety protection device. The utility model is characterized in that the safety protection device is provided with two pressure protection device and temperature protection device arranged in a divided way; namely, a safety hole path is arranged in the valve body; the safety hole path is connected with two branches; one branch of the hole path is connected with the pressure protection device and the other branch of the hole path is connected with the temperature protection device. The utility model can safely discharge the gas when either of the pressure or the temperature reaches the arranged value, and can meet the application in the sites where the pressure and temperature are respectively required to be protected.
Description
Technical field
The utility model relates to other class vehicle body fittings technical field not to be covered, also relates to valve technology field simultaneously, especially relates to the safety protection device of gas cylinder in use for fuel gas automobile valve.
Background technique
At present, light passenger train, car class novel gas automobile adopt pressurized gas and liquefied petroleum gas (LPG) gasoline replacing and diesel oil to act as a fuel, and have the advantage that fuel cost is low, pollution emission is few; For requiring the start-stop device of action at a slow speed on the reservoir vessel in the Motor Vehicle gas supply system, generally without the faucet type ball valve, normally adopt liquefied petroleum gas cylinder valve one class valve commonly used as family, the safety protection device of such valve is to adopt a safe duct is set in valve, stack pressure security sheet and low melting alloy in the duct and make the temperature safety member, during use, when pressure and temperature all reached setting value, gas breaks through the pressure security sheet and temperature safety member assemblying body effluxes; This structure exists certain hidden danger, promptly work as temperature and surpass, and pressure does not arrive, and the pressure security sheet does not destroy; gas can not efflux, otherwise or, pressure surpasses; and temperature does not arrive, and also can not guarantee that gas effluxes, and the occasion that the pressure and temperature that can not meet the demands is protected is respectively used.
Summary of the invention
The purpose of this utility model is at the problems referred to above; a kind of gas cylinder in use for fuel gas automobile valve that improves safety protection device is provided; make pressure and temperature each when reaching setting value, all gas safety can be discharged, can satisfy the claimed respectively occasion of pressure and temperature and use.
For achieving the above object; the technical solution of the utility model is such: a kind of gas cylinder in use for fuel gas automobile valve that improves safety protection device; be to make pressure and temperature combined protection in the former safety installations into separately protection; connect two ducts on the safe duct that promptly in valve, is provided with; wherein a duct connects pressure protective device, another duct jointing temp protective gear.
Owing to adopted technique scheme; a kind of gas cylinder in use for fuel gas automobile valve that improves safety protection device of the present utility model; make pressure and temperature when each reaches setting value, all gas safety can be discharged, can satisfy the claimed respectively occasion of pressure and temperature and use.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is a structural representation of the present utility model.
Among the figure: 1, handwheel, 2, valve body, 3, Zhi Kongdao, 4, leakage port, 5, the temperature safety member, 6, the pressure security sheet, 7, Zhi Kongdao, 8, safe duct.
Embodiment
Shown in accompanying drawing, a kind of gas cylinder in use for fuel gas automobile valve that improves safety protection device of the present utility model comprises valve body 2, opens and closes assembly and safety protection device, and opening and closing on the assembly has handwheel 1; It is characterized in that, said safety protection device, pressure protective device and temperature protective device two-part of having branch to be arranged, promptly in valve body 2, be provided with safe duct 8, on this safe duct, connect two ducts 3,7, wherein a duct 7 connects pressure protective device, another duct 3 jointing temp protective gears;
Said pressure protective device, be to adopt pressure security sheet 6, this pressure security sheet is the part of sphere, contact with the parts of its supporting are slick and sly, the parts of supporting are provided with vent, and when the superpressure explosion, the pressure security sheet is to destroy behind the drawn, changed in the past that the pressure security sheet contacts with the parts of its supporting with plane, the structure that damages because of shearing; Overcome the defective that ubiquitous in the past bursting pressure is unstable and service time is short;
Said temperature protective device, be to adopt piston cylinder operator, promptly the temperature safety member made from low melting alloy 5 is a piston, place in the Zhi Kongdao 3, a leakage port 4 is arranged on the Zhi Kongdao 3, this leakage port is sealed by temperature safety member 5 at ordinary times, when temperature reaches setting value, 5 fusions of temperature safety member promote bottom offset at air pressure, and Zhi Kongdao 3 is communicated with and exhaust with leakage port 4; Play the Zhi Kongdao 3 of piston rod effect, with temperature safety member 5 junction points, its cross section is exaggerated, so that temperature safety member 5 just can produce displacement under slight pressure, opens discharge channel.
Claims (3)
1, a kind of gas cylinder in use for fuel gas automobile valve that improves safety protection device; comprise valve body (2), open and close assembly and safety protection device; it is characterized in that: said safety protection device; pressure protective device and temperature protective device two-part of having branch to be arranged; promptly in valve body (2), be provided with safe duct (8); connect two ducts (3,7) on this safe duct, wherein a duct (7) connects pressure protective device, another duct (3) jointing temp protective gear.
2, a kind of gas cylinder in use for fuel gas automobile valve that improves safety protection device according to claim 1; it is characterized in that: said pressure protective device; be to adopt pressure security sheet (6), this pressure security sheet is the part of sphere, contacts with the parts of its supporting are slick and sly.
3, a kind of gas cylinder in use for fuel gas automobile valve that improves safety protection device according to claim 1, it is characterized in that: said temperature protective device, be to adopt piston cylinder operator, promptly the temperature safety member made from low melting alloy (5) is a piston, place in the Zhi Kongdao (3), one leakage port (4) is arranged on the Zhi Kongdao (3), and this leakage port and Zhi Kongdao (3) are for being connected; Play the Zhi Kongdao (3) of piston rod effect, with temperature safety member (5) junction point, its cross section is exaggerated.
