Abstract

A valve timing closing device of a gas pipeline comprises a coil spring, a gear transmission component, a timing component, a valve opening and closing component and an emergency push button component, wherein the coil spring is installed inside cavities of an upper casing with a knob and a lower casing with a knob, and the emergency push button component which is mounted on the upper casing is matched with an emergency push button connected with the timing component and an emergency push button with a spring. By being directly installed onto an indoor valve of a user without modifying the original valve and pipeline, the valve timing closing device of a gas pipeline is highly practical, accordingly has the function of timing closing, and is capable of leading users who usually forget to turn off valve switches to eradicate safety hazards. Besides, the valve timing closing device is provided with an emergency closing mechanism so as to be capable of adjusting service time and enabling the users to close the valve manually according to the specific using condition of users, accordingly the valve timing closing device not only saves gas consumption but also avoids various accidents caused by forgetting to turning off valve switches, is more flexible and convenient to use, and capable of preventing accidents caused by leakage. In addition, the valve timing closing device of a gas pipeline has dual protection functions and is safe and reliable to use.

Description

Gas pipe valve regularly closing device

Technical field

The utility model relates to the safety installations that uses on a kind of valve of gas pipeline, particularly a kind of gas pipe valve regularly closing device that is used to be installed on indoor liquid gas of user or the natural gas line valve.

Background technique

Development along with modernization, liquid gas or rock gas gas pipeline have entered ordinary family, for the common people provide easy to use, the energy of cleaning, yet be accompanied by the generation of hidden danger after convenient again, China is very high because of occupying the improper accident rate that takes place of domestic gas every year, main cause is often to forget the switch of close chamber's interior conduit valve because of a lot of users, because artificial carelessness has stayed very big potential safety hazard, a lot of combustion gas have not only been wasted, also can be because of combustion gas leakage initiation fire and blast and poisoning, the another one reason, exactly because the rubber hose that transfers to cooking stove from pipeline is failed often transposing and wearing out, the easiest to cause the leakage of combustion gas also be a kind of unsafe hidden danger.Also have the leakage etc. of gas appliances self such as gas valve, gas water-heater all multifactor.

The patent No. 94239485.2 " gas valve time switch " is though also provide a kind of time switch that is installed on the valve, this construction of switch complexity, many, the difficult making of part, difficult installation, inconvenient operation, poor practicability.

The patent No. 02244785.7 " domestic gas liquefied gas tank and liquefied gas pipeline valve switch clutch ", this patent adopt micro motor to make drive unit, utilize the changement control of ganged switch circuit and making and settlement, and its structure is complicated, also needs consumed power.

Summary of the invention

Technical problem to be solved in the utility model is, a kind of gas pipe valve regularly closing device is provided, it is simple in structure, easy to use, energy set time automatic-closing valve, but maybe need adjust emergency cut-off service time timer switch if gas leakage takes place, avoid the generation of gas leakage accident.

The technical scheme in the invention for solving the above technical problem is: gas pipe valve regularly closing device, comprise the upper shell and the interior wind spring of lower shell body cavity that are installed in the band knob, gear-driven assembly, timing component, the valve switch assembly, also comprise the danger button assembly that is installed on the upper shell, described danger button assembly is cooperated with timing component by the danger button that is connected with spring, described timing component is by the timer that is installed in successively on the timer shaft, the spring first, timer gear, driving cog, collar is formed, described gear-driven assembly is by the driving gear that is connected on the upper shell, the valve gear that is connected on the lower shell body links into an integrated entity through gear cover, and driving gear and be connected upper shell and lower shell body on driven gear and timer gear engagement form, described valve switch assembly is made up of the spring second and the bonnet that are installed in the valve gear, is connected with the switch of pipeline valve by bonnet.

Compared with prior art, advantage of the present utility model is: this device is directly installed on the switch of user's interior conduit valve, and original valve and pipe-line need not done any change and just can use, therefore there is not the restriction of installation, practical, this apparatus structure is simple in addition, compact, volume is little, easily install, and be mechanical structure, safe and convenient to use, because of it has regularly closing function, just can make the user who often forgets the throttle down switch fundamentally eradicate hidden danger, wear out or gas appliance because of rubber hose simultaneously, gas valve uses wearing and tearing for a long time, leak by self and cause that the problem of leakage also is readily solved, this device is gone up and is also had emergency cut-off mechanism in addition, according to user's concrete use condition, all can adjust service time at any time and in time close danger button with hand, make the user in handling the emergency incident of leaking or in flurried, reach the effect that a key is closed.Promptly save gas and avoided because of forgetting the various accidents that carelessness caused of throttle down switch; use more flexible, convenient; and all can close the generation that danger button is prevented leakage accident at any time, this device has double protection functions, and is safe in utilization, reliable.
