Abstract
The invention relates to a steel-plastics ball valve structure. The steel-plastics ball valve structure comprises a main valve body. A vice valve body and valve seats are arranged in the main valve body. A center cavity is formed among the main valve body, the vice valve body and the valve seats. The valve seats are arranged in two and a ball body is arranged between the two valve seats. A valve rod is assembled at the top of the ball body. The valve rod is arranged in a valve rod seat of the main valve body. Polyethylene (PE) sleeves are arranged at both an inlet and an outlet of the vice valve body. Dispersing pipes are arranged at both the inlet and the outlet of the vice valve body. A heightening device is arranged on the valve rod. PE anticorrosive coatings are arranged on the surfaces of the main valve body and the vice valve body. According to the steel-plastics ball valve structure, the vice valve body can be connected with PE pipelines through the PE sleeves arranged at the inlet and the outlet. Discharging and dissipating of media in the pipelines can be achieved through the dispersing pipes arranged at the inlet and the outlet of the vice valve body, so that maintenance or modification of the discharged and dissipated pipelines is conducted. A center cavity dispersing leakage detecting pipe arranged on the center cavity can judge whether the sealing of a valve is good or not rapidly. The PE anticorrosive coatings arranged on the surfaces of the valve body can prevent the surfaces of the steel-made valve from being corroded.
Description
Technical field
The present invention relates to a kind of ball-valve structure in technical field of valve manufacturing, especially relate to high-performance antiseptic steel-plastic ball-valve structure.
Background technique
City gas transmission and distribution pipeline domestic at present uses PE pipeline on a large scale, the valve major part of PE install pipeline is PE valve, heat-melting butt-joint or electric capacity is generally adopted to connect with the connection of pipeline, easy to connect, PE material corrosion resistance is good, but because PE material is by temperature, the factor impacts such as settlement stress are larger, reliability and the Security of PE valve are poor, therefore also wish to adopt reliability on PE pipe, the steel that Security is good or irony valve, but traditional linkage structure or Placement cannot be used for the connection of steel or irony valve and PE pipeline, therefore, produce the advantage in conjunction with PE material and steel or irony valve, the gas valve be applicable in city gas transmission and distribution pipeline is the current important technological problems needing to solve.
Summary of the invention
Technical problem to be solved by this invention is to provide one and can be connected with PE pipeline and corrosion resistance is good, and ball-valve structure moulded by reliability, the steel that Security is good.
The present invention solves the technological scheme that its technical problem takes: ball-valve structure moulded by a kind of steel, comprise main valve body, auxiliary valve body and valve seat is provided with in described main valve body, described main valve body, a lumen is formed between auxiliary valve body and valve seat, described valve seat has two, spheroid is provided with between the valve seat described in two, valve rod is equipped with at described spheroid top, described valve rod is arranged in the valve rod base of main valve body, described auxiliary valve body import and outlet PE sleeve is all set, described auxiliary valve body import and outlet port are equipped with exhaust stack, described valve rod is provided with heightening device, on the surface of described main valve body and auxiliary valve body, PE anticorrosive coat is set, described PE anticorrosive coat is integrated molding and forming.
Concrete further, described main valve body is provided with lumen and diffuses leak detection tube and be communicated with lumen, and described lumen diffuses leak detection tube and is provided with and diffuses small ball.
Concrete further, described exhaust stack is provided with and diffuses ball valve.
Concrete further, the middle part of diffusing leak detection tube and exhaust stack at described heightening device, lumen is provided with fixing clamping plate.
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 invention has the beneficial effects as follows: after have employed said structure, the PE sleeve arranged by import and the outlet of auxiliary valve body can realize being connected with PE pipeline; The exhaust stack arranged by import and the outlet of auxiliary valve body can be realized carrying out row to the medium in pipeline and fall apart, thus keeps in repair arranging the pipeline fallen apart or transform; The lumen arranged by lumen diffuses leak detection tube can judge valve seal quality fast, can stop steel valve surface etching by the PE anticorrosive coat arranged in valve body surface.
