After adopting above -mentioned structure, mould plastics through the surface to the main valve body, deputy valve body that the one deck anticorrosives, the anticollision layer, and this layer thickness is not less than 5mm, the material adopts the PE plastics, effectively protects valve metal surface not corrode, does not collide.
Description
Technical field
The utility model relates to a kind of ball valve in valve manufacturing technology field, especially relates to a kind of anticorrosion crashproof steel globe valve structure.
Background technique
The steel valve anticorrosion structure that city gas transmission and distribution pipeline domestic at present adopts, be generally spray paint structure, due to the restriction of valve mechanism and the many factors such as spraying equipment, method, paint may be caused in conjunction with rate variance, spray uneven result, thus have influence on the surface anticorrosion of steel valve, decrease the working life of valve; And in steel valve installation process, valve exterior surface anticorrosive coat likely can be come off by sharppointed article collision, even can leave pit at valve body place, decrease valve body wall thickness; Thus have influence on the reliability and security of valve.Therefore, produce high performance corrosion protection, the structure of anticollision is the current important technological problems needing to solve.
Summary of the invention
Technical problem to be solved in the utility model is to provide and is a kind ofly less likely to occur to corrode and can reduces the good corrosion-resistant steel globe valve structure of reliability, the Security of collision impact.
The technical scheme in the invention for solving the technical problem is: a kind of anticorrosion crashproof steel globe valve structure, comprise main valve body, auxiliary valve body is provided with in described main valve body inside, described auxiliary valve body is provided with valve seat, described valve seat has two, spheroid is provided with between the valve seat described in two, valve rod is provided with at described spheroid top, described valve rod is arranged on the valve rod base on main valve body, described main valve body, the surface of auxiliary valve body are provided with the anticorrosion crashproof layer of PE, the anticorrosion crashproof layer of described PE adopts injection moulding integrated molding, and thickness is not less than 5mm.
Concrete further, the import of described auxiliary valve body and outlet port are equipped with an exhaust stack.
Concrete further, the main valve body on described valve rod base side is provided with and adds high-base.
Concrete further, be provided with elastic element between described auxiliary valve body and valve seat, between described valve seat and spheroid, be provided with Sealing.
Concrete further, described elastic element is butterfly spring or helical spring.
Concrete further, the bottom of described main valve body arranges a positioning shaft, and bottom described spheroid, intermediate shaft hole position is arranged on positioning shaft.
The beneficial effects of the utility model are: after adopting said structure; by the surperficial injection moulding one deck corrosion protection to main valve body, auxiliary valve body, anticollision layer, and the thickness of this layer is not less than 5mm, and material adopts PE plastics; available protecting valve metal surface is not corroded, and does not collide.
