Abstract
A kind of safety valves for gas that is installed in combustion gas user pipe terminal is installed a gear that has spring on its handwheel, this gear links to each other with mechanical timer by a driving gear.When the user uses combustion gas, at first the rotary timer knob determines to use the gas time, rotation hand wheel again, open safety valves for gas, just can light kitchen range, spring on the gear is tightened up, and gear is given mechanical timer energy transport by driving gear when rotating with handwheel, driving gear blocks in the office that is located at simultaneously in the mechanical timer, guarantee that opened safety valves for gas can be by springs return, the usefulness gas time that the user sets, the office in the mechanical timer was opened when arriving, the energy that is stored in the mechanical timer discharges by driving gear, and pass to gear, under the acting in conjunction of driving gear and spring, valve is closed automatically.The user can reset the gas time of using at any time by timer knob during use, also can use the handwheel throttle down.
Description
Technical field
The utility model relates to a kind of safety valves for gas that is installed in combustion gas user pipe terminal.
Background technique
Along with the develop rapidly of national economy, huge variation has taken place in resident's fuel structure, and coal gas, rock gas become people's necessity just as water, electricity.Simultaneously, the generation of gas accidents also becomes a threat greatly of resident's safety.Gas pipeline all passes through bulge test and strict examination in work progress.So, the accident frequency that the accident frequency that causes because of the gas pipeline leakage reasons causes well below user's improper use.The valve that is installed in user terminal at present mostly is the special-purpose ball valve of combustion gas, to the alarm then how safe in utilization of user prompt combustion gas leakage.But, revealing the fire cause, blast, intoxication accident because of the terminal combustion gas and often under the user can't answer the situation of warning, take place, this explanation combustion gas terminal use exists potential safety hazard.
Summary of the invention
Exist potential safety hazard in order to solve the combustion gas terminal use, the utility model provides a kind of safety valves for gas, has solved when user terminal generation combustion gas is revealed, and the user can't answer the safety problem under the alarm condition.
The technological scheme that its technical problem that solves the utility model adopts is: replace the special-purpose ball valve that present combustion gas terminal use uses with safety valves for gas, be equipped with a gear that has spring on the handwheel of this safety valves for gas, this gear that has spring links to each other with mechanical timer by a driving gear.When the user uses combustion gas, must determine to use the gas time by the rotary timer knob earlier, rotation hand wheel again, open safety valves for gas, light kitchen range then, spring on the gear is tightened up simultaneously, gear is when rotating with handwheel, give mechanical timer energy transport by driving gear, driving gear blocks in the office that is located at simultaneously in the mechanical timer, to guarantee that opened safety valves for gas can be by springs return, the usefulness gas time that the user sets, the office in the mechanical timer was opened when arriving, the energy that is stored in the mechanical timer discharges by driving gear, and pass to the gear that is installed on the handwheel, under the acting in conjunction of driving gear and spring, valve is closed automatically.If the user does not at first determine to use the gas time by timer, open valve rear spring meeting automatic self-closing gas safety valve, can't use gas.In use the user can reset the gas time of using at any time by timer knob, also can use the handwheel throttle down.
The effect that the utility model is useful is: the user terminal valve can be closed automatically by the time that the user sets under unattended situation, and this just can be avoided taking place combustion gas and reveal the generation that causes accidents such as fire under user's operator-less situation.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further
Fig. 1 is a cut away view of the present utility model.
Embodiment
The utility model is made up of valve (1), spring (2), gear (3), handwheel (4), driving gear (5), mechanical timer (6), timer knob (7).
When the user uses combustion gas, the timer knob (7) that rotation is installed on the mechanical timer (6) determines to use the gas time, the handwheel (4) that rotation links to each other with valve (1), the spring (2) that is installed in when opening safety valves for gas on the gear (3) is tightened up, be installed in gear (3) on the handwheel (4) when rotating with handwheel (4), give mechanical timer (6) energy transport by driving gear (5), driving gear (5) blocks in the office that is located in the mechanical timer (6), guarantee that opened safety valves for gas can not retracted by spring (2), the usefulness gas time that the user sets is when arriving, the office that is located in the mechanical timer (6) is opened, the energy that is stored in the mechanical timer (6) discharges by driving gear (5), and pass to the gear (3) that is installed on the handwheel (4), under the acting in conjunction of driving gear (5) and spring (2), valve (1) is closed automatically.In use the user can reset the gas time of using at any time by timer knob (7), also can use handwheel (4) throttle down (1).
Claims (2)
1, a kind of safety valves for gas that is installed in combustion gas user pipe terminal is made up of valve (1), spring (2), gear (3), handwheel (4), driving gear (5), mechanical timer (6), timer knob (7), it is characterized in that: the handwheel (4) that links to each other with valve (1) is gone up gear (3) is installed, and gear (3) is gone up mounting spring (2).
2, safety valves for gas as claimed in claim 1 is characterized in that: mechanical timer (6) links to each other with gear (3) by driving gear (5).
