Abstract
The invention discloses a two-position normally open type pilot valve capable of being controlled by a mechanical ejector rod. The two-position normally open type pilot valve comprises a valve body. A valve base and a valve deck are arranged on the valve body. A valve rod is arranged between the valve base and the valve deck. A turning plate is arranged in a fluid passageway in the valve body. A pair of elastic pieces are arranged on the valve deck and connected through a cover plate. A small hole is formed in the cover plate. The tail end of the valve rod penetrates out of the small hole in the cover plate. The valve rod and the turning plate are connected through screws. The elastic pieces and the cover plate are integrally formed. The turning plate is made of copper-nickel alloy. A layer of sealing rubber is arranged on the surface of the turning plate. According to the two-position normally open type pilot valve capable of being controlled by the mechanical ejector rod, the pair of elastic pieces are arranged on the valve deck, and the tail end of the valve rod penetrates out of the small hole in the cover plate connected with the elastic pieces. When the mechanical ejector rod controls the valve rod to rotate, the elastic pieces exist between the mechanical ejector rod and the valve body to be used for protection, the mechanical ejector rod cannot make direct contact with the valve body, and the safety of the valve body is improved.
Description
Technical field
The present invention relates to a kind of pilot valve, more precisely, be a kind of two open type pilot valves that can be controlled by mechanical jack.
Background technology
Pilot valve is that one utilizes medium energy, with the less method controlling energy hole large bore valves opening and closing.Two the open type pilot valves that can be controlled by mechanical jack, during mechanical jack control, valve rod and valve body are easily caused mechanical shock by push rod, damage valve body itself.
Summary of the invention
The present invention mainly solves the technical problem existing for prior art, thus provides a kind of two open type pilot valves that can be controlled with higher safety by mechanical jack.
The above-mentioned technical problem of the present invention is mainly addressed by following technical proposals:
A kind of two open type pilot valves that can be controlled by mechanical jack, comprise a valve body, described valve body is provided with a valve seat and a valve gap, described valve seat and valve cover chamber are provided with a valve rod, being provided with a turnover panel in described valve body fluid passage, be provided with a pair flexure strip on described valve gap, described flexure strip is connected by a cover plate, described cover plate passes with aperture, the end of valve rod aperture from cover plate.
As preferred embodiment of the present invention, connect for screw between described valve rod and turnover panel.
