Description

Leakage protection device for gas valve

Technical Field

The utility model relates to the field of fuel gas, in particular to a leakage protection device for a fuel gas valve.

Background

The gas valve can control the passage of gas in the gas pipeline, is an indispensable component in the pipeline, but the valve needs to be installed in the pipeline as a separate piece, even if the installation mode is ingenious again, the valve and the pipeline are not one component after all, and along with the use of the pipeline, the gap between the valve and the valve gradually generates, so that the gas is leaked.

The gas leakage is detected by a special instrument, but is generally detected under the condition that the leakage occurs, not real-time monitoring, if the leakage of the pipeline is not detected, the danger is very likely to happen, and even if the leakage of the pipeline is detected, the leaked gas can be harmful if not treated properly.

Disclosure of Invention

Aiming at the defects existing in the prior art, the utility model aims to provide a gas valve leakage protection device which solves the existing pain point in the field.

The technical aim of the utility model is realized by the following technical scheme:

the utility model provides a protection device is revealed to gas valve, includes two amalgamation frames, the amalgamation frame includes both sides makeup and two amalgamation boards, two amalgamation frame shape symmetry, two amalgamation frames rotate and install in opening and shutting the pivot, two amalgamation frames can amalgamate together, the side makeup with amalgamation board amalgamation limit all is provided with the sealing strip, the side makeup with amalgamation board middle part all is provided with the recess, install the sealing ring in the recess of side makeup, two the sealing ring can encircle the gas pipe, install the embracing ring in the recess of amalgamation board, two embracing rings can encircle the valve shaft, amalgamation frame side edge is provided with the elastic membrane, the elastic membrane edge all adheres on the amalgamation frame, the elastic membrane middle part is walked around the pivot is opened and shut.

Optionally, a buckle is arranged on the splicing plate.

Preferably, an alarm mechanism is provided on the split frame.

Optionally, the alarm mechanism may include a push plate hinged to a side of the split plate, where the push plate can be pushed by the expanded elastic membrane to rotate, and a compression rod is fixedly installed at the other end of the push plate, and a piezoelectric switch is disposed on the split plate and connected with the alarm.

In summary, compared with the prior art, the utility model has the following beneficial effects: the device can hang in gas pipeline valve department, and inside is the enclosure space when the device is closed, and the valve is contained wherein, if the valve junction takes place to leak the condition, the gas that leaks will be kept in the device, avoids being inhaled by the people, avoids gas and electrical apparatus contact simultaneously to prevent the electric spark to ignite the gas and cause irrecoverable loss, and the elastic membrane can be propped up by gas, can let the gas leakage condition of people audio-visual observation, need not to use gas leakage detector constantly to detect.
