Abstract

The utility model relates to the technical field of gas diffusion valve manufacturing, especially to a ground buried gas diffusion valve for gas, which comprises a hollow cylindrical tube and two valve bodies at both sides of the tube. The cross sectional areas of both the two valve bodies are bigger than that of the tube body. The polyethylene made gas diffusion valve of the utility model is provided with a long connection rod structure made from metal, whose yield strength is big to make the gas diffusion valve have a smaller size and a simpler structure, compared with a plastic made one, to have the same load. In addition, the expansion and contraction coefficient of the product is also small with the result that the product is not subject to the change of surrounding temperatures. The product can also be tailored to have a super-long structure with different length dimensions to meet the requirements of both customers and the market.

Description

A kind of combustion gas with the valve that gives out of gas with burying

Technical field

The utility model relates to the valve correlative technology field that gives out of gas, and particularly a kind of combustion gas with the valve that gives out of gas with burying.

Background technique

At present, combustion gas is all adopted plastic material with burying ground polythene (PE) valve---the long extension bar that gives out of gas; Its major defect; Be that volume is big, form structure is complicated, expand with heat and contract with cold significantly, low-temperature embrittleness (40 ℃); Environmental Conditions receives certain narrow limitation, can not satisfy market and client's demand fully.

The model utility content

The utility model provides a kind of combustion gas with the valve that gives out of gas with burying, to solve the technical problem that existing technology exists.

The utility model adopts following technological scheme to realize:

A kind of combustion gas with the valve that gives out of gas with burying, and the said valve that gives out of gas comprises the cylindrical tube of boring, and two valve bodies that are separately positioned on the body both sides, and the cross-section area of said valve body is greater than the cross-section area of body.

As a kind of preferred version, said valve inner hollow comprises a U type piece and two square blocks that are connected with U type piece both sides.

As further preferred version, said U type piece and two square blocks are through being welded to connect.

As a kind of preferred version, said two valve bodies big or small identical.

The utility model provides a kind of combustion gas with burying ground polythene (PE) the long extension bar structure of valve-metal that gives out of gas; Its yield strength is big, and it is little under same load, to compare the plastics volume, simple in structure; Coefficient of thermal expansion and contraction is little; Use the influence that does not receive ambient temperature, can be designed to the super-long structural of different length size according to market and client's demand.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed explanation.

Embodiment

Fig. 2 is the stereogram of the utility model, present embodiment be a kind of combustion gas with the valve that gives out of gas with burying, its structure characteristic is:

1, elongated, the boring of intermediate portion belongs to the cylinder pipe part.

2, two heads congruence is respectively by a U-shaped piece and two square block welding, the square body of the likeness in form ghost that partners.

3, short big, the intermediate elongated of two heads, welding back integral body is dumbbell shaped.

The valve that gives out of gas comprises the cylindrical tube 1 of boring; And two valve bodies that are separately positioned on the body both sides; The cross-section area of said valve body is greater than the cross-section area of body; Valve inner hollow, comprise a U type piece 2 and with U type piece both sides big or small identical through 3, two valve bodies of two square blocks of being welded to connect.

Claims

1. a combustion gas is characterized in that with the valve that gives out of gas the said valve that gives out of gas comprises the cylindrical tube of boring with burying, and two valve bodies that are separately positioned on the body both sides, and the cross-section area of said valve body is greater than the cross-section area of body.

2. the valve that gives out of gas according to claim 1 is characterized in that, said valve inner hollow comprises a U type piece and two square blocks that are connected with U type piece both sides.

3. the valve that gives out of gas according to claim 2 is characterized in that, said U type piece and two square blocks are through being welded to connect.

4. the valve that gives out of gas according to claim 1 is characterized in that, said two valve bodies big or small identical.
