The utility model discloses simple structure, it is convenient to make, can not destroy valve strength, satisfies high-pressure acetylene and carries the requirement.
Description
Technical Field
The utility model relates to a carry valve for high-pressure acetylene.
Background
Acetylene is a common chemical raw material which is very easy to explode, high-pressure acetylene with the working pressure of 0.15MPa is more easy to decompose and explode, and the sub-pipe is used for rapidly dispersing heat to prevent heat from being accumulated to explode.
Disclosure of Invention
The utility model aims at providing a carry valve for high-pressure acetylene, the utility model discloses simple structure, it is convenient to make, can not destroy valve strength, satisfies high-pressure acetylene and carries the requirement.
The technical scheme of the utility model is that: the utility model provides a carry valve for high-pressure acetylene, includes valve and case, its characterized in that: sub-pipes are filled between the valve core and the sealing surface of the valve, the distance between any sub-pipe in the valve is not more than 10mm, the sub-pipes are fixed by spot welding, and the sub-pipes are fixed by spot welding with the inner wall of the valve, so that no relative movement between the sub-pipes and the valve is ensured.
Preferably, the sub-pipe is integrally filled in a conical shape, is tightly filled and is flush, and the section of the sub-pipe is guaranteed to be 3mm away from the sealing surface of the valve.
Preferably, to ensure the valve to be normally opened and closed, the sub-pipe is 6mm away from the valve core.
Preferably, the valve must be a stopcock.
The utility model discloses simple structure, it is convenient to make, can not destroy valve strength, satisfies high-pressure acetylene and carries the requirement.
Drawings
Fig. 1 is a schematic diagram of the present invention.
Detailed Description
As shown in figure 1, the valve for conveying high-pressure acetylene comprises a valve core and a valve 1, a sub-pipe 2 is filled between the valve core and a sealing surface of the valve, the sub-pipe 2 is fixed by spot welding with the inner wall of the valve 1, and no relative movement between the sub-pipe 2 and the valve 1 is ensured.
The specification of the sub-pipe 2 is divided into two types:
and
the distance between any sub-pipe in the valve 1 is not more than 10mm, and the sub-pipe and the valve body are made of the same material.
The sub-pipe 2 is integrally filled in a conical shape, is compactly filled and is parallel and level, and the distance between the section of the sub-pipe and the sealing surface of the valve is guaranteed to be 3 mm.
In order to ensure the normal opening and closing of the valve 1, the sub-pipe 2 is 6mm away from the valve core.
The valve must be a stopcock.
The above-mentioned specific embodiments further explain in detail the technical problems and technical solutions of the present invention. It should be understood that the above description is only exemplary of the present invention and is not intended to limit the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
