The utility model discloses a kind of shutoff valve on gas flowmeter, including closing valve body, described closing valve body one end is connected with handle, the closing valve body other end is provided with some back-offs, the closing valve body periphery is provided with a pair of clasps, the pair of clasp is symmetrical arranged according to shutoff valve main center, the clasp is L-shaped, fixing groove is formed between the clasp and closing valve body periphery, some limited steps are also equipped with the closing valve body periphery, the limited step is between back-off and clasp.Pass through the setting of some back-offs, a pair of clasps and some limited steps, the assembling of shutoff valve and gas flowmeter can be achieved, without opening up screw hole in shutoff valve and gas flowmeter, improve efficiency of assembling, assembly cost is reduced, and the structure after assembling is more stable.
Description
Technical field
It the utility model is related to a kind of shutoff valve.
Background technology
Shutoff valve on gas flowmeter, primarily serve the effect closed into outlet passageway, if subscriber arrearage or
When there are other unusual conditions, can by the shutoff valve come prevent combustion gas by using.The shutoff valve mostly passes through at present
Assembling is fixed, it is necessary to open up corresponding screw hole on shutoff valve, gas flowmeter in screw, fixes in this way
The shortcomings that certain be present in assembling：I.e. assembling is inconvenient, and cost is high, and the structural instability after assembling.
The content of the invention
In order to solve above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of convenient for assembly and structure
The stable shutoff valve being used on gas flowmeter.
To achieve these goals, a kind of shutoff valve on gas flowmeter designed by the utility model, including
Valve body is closed, described closing valve body one end is connected with handle, and the closing valve body other end is provided with some back-offs, the pass
Valve closing main body periphery is provided with a pair of clasps, and the pair of clasp is symmetrical arranged according to shutoff valve main center, and the clasp is in L
Type, fixing groove is formed between the clasp and closing valve body periphery, some limits are also equipped with the closing valve body periphery
Position step, the limited step is between back-off and clasp.
Preferably, some back-offs are circumferentially distributed around the center line for closing valve body.
Preferably, some back-offs are distributed around the center line for closing valve body in circumference in equal parts.
Compared with prior art, a kind of shutoff valve on gas flowmeter that the utility model obtains, it is beneficial to effect
Fruit is：Pass through the setting of some back-offs, a pair of clasps and some limited steps, you can realize shutoff valve and gas flowmeter
Assembling, without opening up screw hole in shutoff valve and gas flowmeter, efficiency of assembling is improved, reduces assembly cost, and
Structure after assembling is more stable.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples.
As shown in figure 1, a kind of shutoff valve on gas flowmeter, including close valve body 1, the closing valve body
1 one end is connected with handle 2, and the closing other end of valve body 1 is provided with some back-offs 3, and in the present embodiment, the back-off 3 includes oneself
Close valve body 1 and extend the extension 31 to be formed away from the direction of handle 2, and from extension 31 away from closing valve body 1 one end
Extend the canned paragraph 32 to be formed away from the center position of valve body 1 is closed, the canned paragraph 32 is vertically arranged with extension 31, and institute
Stating canned paragraph 32 has certain elasticity, and closing valve body 1 periphery is provided with a pair of clasps 4, the pair of basis of clasp 4
The center symmetric setting of valve body 1 is closed, the clasp 4 is L-shaped, is formed and fixed between the clasp 4 and closing valve body 1 periphery
Groove 5, described close on the periphery of valve body 1 are also equipped with some limited steps 6, and the limited step 6 is located at back-off 3 and clasp 4
Between.
Some back-offs 3 are circumferentially distributed around the center line for closing valve body 1.In the present embodiment, the quantity of back-off
For ten, and it is distributed around the center line for closing valve body 1 in circumference in equal parts, in this way, the steady of assembling can be greatly improved
It is qualitative.
Assembling when, blocked as long as back-off 3 is stretched into the pipeline of gas flowmeter, fixing groove 5 respectively with pipeline
Wall, periphery abut against, that is, complete the assembling of shutoff valve and gas flowmeter, substantially increase assembling speed, reduce and be assembled into
This, and the structure after assembling is more stable.
