The utility model has the advantages of reasonable design, sealed effectual, long service life can utilize under - 150 DEG C -200 DEG C temperature, and the range of application is extensive.
Description
Technical field
The utility model designs a kind of flap type, a kind of long service life of specific design, the wide high sealing dark rod flat plate valve of temperature range of application.
Background technology
Flat gate valve is that a kind of closure member is the slide-valve of parallel gate plate. Its closure member can be single disc or therebetween with the double disc of spreading mechanism, flat gate valve can be divided into manual flat gate valve, Pneumatic flat-plate gate valve and driven plate gate valve by type of drive. Can be divided into by purposes and use occasion have pod apertures flat gate valve, without pod apertures flat gate valve, oil field flat gate valve, pipeline flat gate valve and gas flat plate gate valve etc. Be widely used in oil, natural gas transmission pipeline.
But the design of the dark rod flat plate valve arrangement of prior art is reasonable not, between flap type inner valve seat and valve body, adopt rubber as encapsulant, due to rubber easily aged deterioration in long-term use procedure, cause flap type internal leakage, service life is shorter, and applicable temperature range is narrower.
Therefore, necessary a kind of reasonable in design of research and development, long service life, good seal performance, the high sealing dark rod flat plate valve that temperature limit is wide of designing on the basis of prior art.
Summary of the invention
Utility model object: the purpose of this utility model is for a kind of reasonable in design is provided, good seal performance, long service life, can be used for-150 DEG C～200 DEG C high sealing dark rod flat plate valves in temperature range.
Technical scheme: in order to realize the purpose of this utility model, the technical solution adopted in the utility model is:
A kind of high sealing dark rod flat plate valve, it comprises valve body, is arranged on the valve seat of valve inner, is arranged on guide plate and valve plate on valve seat, and valve plate upper end is connected with valve rod, and valve body upper end is provided with valve gap; Between valve gap and valve rod lower end, valve stem nut is installed, between valve gap and valve rod upper end, filler is installed, gland is installed on filler, valve stem tip is connected with valve rod connecting rod, and valve rod connecting rod is connected with handwheel;
A left side for described valve seat, right two sides and valve body junction are provided with PTFE stuffing materials and Elgiloy spring. Between the utility model inner valve seat and valve body, adopt high performance engineering plastics as encapsulant, configure again Elgiloy alloy (Elgiloy) spring and in the violent temperature difference and high pressure high-corrosion medium, kept precompressed elastic force as the truncate source of repaying, realize good sealing effectiveness, and long service life, temperature range is wide.
