The utility model has the characteristic of automatic one-way guiding. The utility model does not damage the performance of the gas meter and can bear main water pressure. The utility model also has the function of sealing gas under the condition of no external force.
Description
Technical field
The utility model relates to a kind of gas meter that measures the coal gas throughput, relates generally to a kind of anti-reverse waterproof gas meter.
Background technology
In the prior art, the normal mounting of gas meter is that inlet suction port is connected with gas piping, and air outlet adapter is connected with user's burner equipment, when coal gas measures during by gas meter, simultaneously the coal gas supplied burner is used.Realize that the coal gas user normally uses coal gas and gas company to carry out the purpose of reasonable fee according to the metered amounts of gas meter.Common gas meter is (outlet side is connected on the inlet end of pipeline) by reversal connection the time, and gas meter still can be ventilated, but does not measure, and certain noise is just arranged.If the user has common gas meter knowledge, can realize stealing the purpose of gas deliberately with the gas meter reversal connection, cause economic loss to gas company.In addition, if the coal gas user receives the air intake opening of water heater on the water pipe because of carelessness, when fetching boiling water tap, tap water will enter gas piping by gas meter, flow meter, will cause imponderable loss.Even gas meter is installed according to normal installation requirement, but, if with the air intake opening misconnection of water heater to water pipe, when fetching boiling water tap, tap water will enter gas piping by gas meter, flow meter, will cause this user pipe water on every side, untimely discovery, even will cause in a big way pipe water, and can not use coal gas, its economic loss is unpredictable.
Summary of the invention
The purpose of this utility model is to overcome the defective of above-mentioned technology, and a kind of anti-reverse waterproof gas meter is provided.Adopt the utility model can prevent that gas meter from being caused by user's reversal connection that gas and mistake are received the potential safety hazard that connecing of gas meter brought on the gas port with water pipe steathily, characteristic with automatic unidirectional conducting, can not damage the performance of gas meter, can bear the ability of tap water pressure, do not having also have the effect of sealing gas under the situation of external force.
The utility model is achieved through the following technical solutions:
A kind of anti-reverse waterproof gas meter comprises gasometer casing and table movement, and it is characterized in that: also include waterproof base plate and retaining valve, described waterproof base plate is fixed on the junction of table movement and gas meter gas outlet, and described waterproof base plate is provided with air hole; Described retaining valve is fixedly set in the one side of waterproof base plate upper edge coal gas airflow direction.
Described retaining valve comprises the rotating shaft base that has rotation axis that is fixedly set on the waterproof base plate, is with splash guard on the rotation axis.
Described rotation axis is that rotary moveable is connected with splash guard.
Described waterproof base plate and rotating shaft base are for being rigidly connected.
The splash guard that described retaining valve comprises a pair of guide pillar that is arranged on the sidewall of gas outlet, is slidingly connected with guide pillar.
Described guide pillar is fixedlyed connected with the gas outlet wall.
Advantage of the present utility model is: owing to increase an one-way cock in the gas outlet of common gas meter, make gas meter both have the characteristic of automatic unidirectional conducting, can not damage the performance of gas meter again, when the user just uses gas always, coal gas flows along airflow direction by gas meter, because coal gas has pressure, therefore splash guard moves under the promotion of coal gas, realize the purpose of automatic valve opening ventilation, as user during normally without gas, splash guard moves downward under the effect of self gravitation, splash guard and waterproof base plate are fitted, realize the purpose of valve-closing, so just can prevent that gas meter from being caused by user's reversal connection that gas and mistake are received the potential safety hazard that connecing of gas meter brought on the gas port with water pipe steathily.Simultaneously, can also bear the ability of tap water pressure, not have also have the effect of sealing gas under the situation of external force.

Mark among the figure: 1 is shell, and 2 are the table movement, and 3 is air outlet adapter, and 4 is the gas outlet, and 5 is the waterproof base plate, and 6 is splash guard, and 7 is rotating shaft base, and 8 is rotation axis, and 9 is guide pillar.
Embodiment
Embodiment 1:
A kind of anti-reverse waterproof gas meter comprises gasometer casing 1 and table movement 2, also includes waterproof base plate 5 and retaining valve, and described waterproof base plate 5 is fixed on the junction of table movement 2 and gas meter gas outlet 4, and described waterproof base plate 5 is provided with air hole; Described retaining valve is fixedly set in the one side of waterproof base plate 5 upper edge coal gas airflow directions, described retaining valve comprises the rotating shaft base that has rotation axis 87 that is fixedly set on the waterproof base plate 5, be with splash guard 6 on the rotation axis 8, waterproof base plate 5 sticks with glue with movement 2 and gas outlet 4 and connects, and be screwed, the splash guard 6 moving axis seat 7 that can rotate is done circular motion, and described rotation axis 8 and splash guard 6 be for rotary moveable is connected, and waterproof base plate 5 and rotating shaft base 7 are for being rigidly connected.
When user's gas just commonly used, coal gas flows along airflow direction by gas meter, because coal gas has pressure, so splash guard is under the promotion at air-flow, and the splash guard moving axis seat that rotates moves upward, and splash guard and waterproof base plate leave, and realize opening the purpose that valve is ventilated.As user during normally without gas, splash guard moves downward under the effect of self gravitation, and splash guard and waterproof base plate are fitted, and realize closing the purpose of valve.If the user will show reversal connection, i.e. air-flow counter motion will be because of the stuffiness of closing of splash guard.If user mistake is received water pipe on the coal gas interface of water heater, tap water in gas meter during flowing water, will because of splash guard is in closed condition can't be to gas piping flowing water.
Waterproof base plate and splash guard all can adopt powder aldehyde material, and it is very little that this material has distortion, the intensity height, in light weight, therefore can bear the effect that hydraulic pressure can play switch again, can significantly not increase crushing (being measured as about 10Pa) again simultaneously, not influence the performance of gas meter.The faying face of waterproof base plate and splash guard can pass through milled processed, guarantees that the flatness of two faces reaches intermittently contact of nothing, plays sealing function.
Embodiment 2:
