Abstract

A gas leakage self-inspection device is characterized in that a transparent and pressure-tight hermetically sealed container is arranged and is filled with liquid therein, two pipes pass through the top cover of the hermetically sealed container to be inserted into the hermetically sealed container, one of the pipes is a gas inlet pipe communicated with a gas supply valve and the end of the pipe is inserted in the position below the liquid level inside the hermetically sealed container, and the other pipe is a gas outlet pipe connected with a terminal gas valve of gas utilization equipment through a quick-opening valve and a connection hose and the end of the gas outlet pipe is positioned in the position above the liquid level inside the hermetically sealed container. The gas leakage self-inspection device is serially connected between the gas supply valve and the gas utilization equipment and can acquire the gas leakage of the gas valves and the gas pipeline by observing the state of the liquid after opening or closing the gas valves.

Description

The gas leakage self-checking unit

Technical field

The utility model relates to gas leak detection device, the specifically a kind of self-checking unit that can observe gas stop valve close situation.

Background technology

A lot of people always worry whether stop valve is fastened after finishing using when using hazardous gas.With the household gas range is example, and people are valve-off after using gas-cooker, is not see whether valve is fastened by naked eyes, and universal experience thinks, even if to put in place be to fasten as long as stop valve is closed, and no longer gas leakage.But this only is the experience judgement, lacks scientific basis.And the slight gas leakage of stop valve is difficult to discover, have only when the gas that spills reaches the concentration that arrives that people can sense of smell hear in the certain space scope, could find, but situation at that time has been very dangerous, careless slightlyly all can have caused serious consequence.

The utility model content

The utility model is for avoiding the existing in prior technology weak point, a kind of multi-functional gas leakage self-checking unit is provided, and whether this device can detect gas stop valve automatically and fasten, and can observe clearly by enough eyes.

The utility model technical solution problem adopts following technical scheme.

The design feature of the multi-functional gas leakage self-checking unit of the utility model is:

The design feature of the utility model gas leakage self-checking unit is that transparent and withstand voltage closed container is set, holding liquid in the described closed container, on the top cover of described closed container, there are two conduits to run through top cover and insert closed container, in described two conduits, the draft tube that the first is communicated with steam supply valve, the pipe end of draft tube is inserted on the following height and position of the interior liquid level of closed container, its another be with gas equipment terminal air valve by quick-opening valve be connected the escape pipe that flexible pipe is connected, the pipe end of described escape pipe is on the above height and position of liquid level in the described closed container.

Compared with the prior art, the beneficial effects of the utility model are embodied in:

1, use of the present utility model is to have judged whether gas leakage by the state of observing liquid in the closed container, whether whole pipelines and each air valve that can detect from steam supply valve to gas equipment terminal air valve have the order of severity of leaking gas and leaking gas, and ocular and clear is simple.

2, the utility model has good filtration to gas when normal the use, can improve the peace and quiet degree of usefulness gas, reduces and pollutes, and improves the service efficiency of combustion gas.

Description of drawings

Fig. 1 is the utility model structural representation.

Number in the figure: 1 steam supply valve, 2 gas inlet pipes, 3 top covers, 4 O-ring seals, 5 vessels, 6 liquid, 7 escape pipes, 8 quick-opening valves, 9 connect flexible pipe, 10 gas equipment terminal air valves.

Below by embodiment, the utility model is described in further detail in conjunction with the accompanying drawings.

Embodiment

Referring to Fig. 1, present embodiment is provided with transparent and withstand voltage closed container, replacing for the ease of assembling and liquid in container, it is to be adopted to be threaded by top cover 3 and vessel 5 to constitute that closed container is set, between the suitable for reading and top cover 3 of vessel 5, O-ring seal 4 is set, to guarantee its airtight performance and resistance to pressure.

Fill liquid 6 in closed container, liquid 6 is water or oil, for the ease of observing, can be to add coloured pigment in liquid 6; On the top cover 3 of closed container, there are two conduits to run through top cover and insert closed container, in two conduits, the draft tube 2 that the first is communicated with steam supply valve 1, the pipe end of draft tube 2 is inserted on the interior following height and position of liquid level of closed container, its another be with gas equipment terminal air valve 10 by being connected the escape pipe 7 that flexible pipe 9 and quick-opening valve 8 are connected, the pipe end of escape pipe 7 is on the above height and position of the interior liquid level of closed container, in order to guarantee the airtight performance of container, top cover 3 is set and two conduits are that transparent pressure-resistant material is directly cast one-piece construction, therebetween without any the slit.

In concrete the enforcement, be that closed container is serially connected between steam supply valve 1 and the gas equipment terminal air valve 10 by draft tube 2 and escape pipe 7.

When just using gas always, because the form of its serial connection, gas from steam supply valve 1 at first enters closed container by draft tube 2, and in liquid 6, filter, phenomenon appears seething in liquid 6 in closed container, enter gas equipment through escape pipe 7, quick-opening valve 8, connection flexible pipe 9 and gas equipment terminal air valve 10 successively again and come into operation;

When closing steam supply valve 1, when opening quick-opening valve 8 and gas equipment terminal air valve 10, if liquid 6 occurs seething or the bubbling phenomenon, then steam supply valve 1 does not cut out and puts in place, as liquid 6 do not seethe or the bubbling phenomenon then steam supply valve closed and put in place;

When open steam supply valve 1 and gas equipment terminal air valve 10, when closing quick-opening valve 8, if liquid 6 is as occurring seething or the bubbling phenomenon, then this device has gas leakage or quick-opening valve 8 not to close and put in place, as do not seethe or the bubbling phenomenon then intact, the quick-opening valve 8 of this device also closed and put in place;

When confirming that after testing this device is under the intact situation, open steam supply valve 1 and quick-opening valve 8, when closing gas equipment terminal air valve 10, if liquid 6 is as occurring seething or the bubbling phenomenon, then connecting flexible pipe 9 has gas leakage, as do not occur seething or the bubbling phenomenon then all are normal.

In the utility model, any one can directly close gas piping as stop valve steam supply valve 1, quick-opening valve 8, gas equipment terminal air valve 10.Of the present utility model installing and using must keep top cover 3 last, vessel 5 under towards, need removable container body 5, or when changing liquid in the vessel 5, one of operator controls top cover 3, top cover 3 is maintained static, and the another hand-screw changes vessel 5, and being threaded between unloading top cover 3 and the vessel 5 gets final product.
