Description
Technical field
This utility model relates to gate valve field, is specifically related to a kind of heavy caliber band bypass and expands pollution discharge type parallel gate valve without pod apertures.
Background technology
Traditional gate valve uses the single, double flashboard structure on band inclined-plane, with the sealing pair on one inclined-plane of valve seat composition, reaches the effect of forced seal by the lower thrust of valve rod.
API 6D flat gate valve has two valve seats floated, and all can seal when each valve seat is designed as both direction media flow.Flat gate valve not only can realize two way seal, and can realize import and export and seal simultaneously.When valve expanded by heating and when causing the pressure of lumen more than pipeline pressure, medium acts on the pressure differential on valve seat both sides will push away gate valve floating valve seat.Gate valve work is the most frequent, pressure is the biggest, and floating valve seat abrasion is the biggest, easily causes the leakage of valve.
Summary of the invention
In order to solve the problems referred to above, the utility model proposes a kind of heavy caliber band bypass and expand pollution discharge type parallel gate valve without pod apertures, design is simple, easy to use, solves floating valve seat and easily weares and teares, causes the technical problem of the leakage of valve, meet applying working condition.
In order to reach foregoing invention purpose, the utility model proposes techniques below scheme:
The bypass of heavy caliber band expands pollution discharge type parallel gate valve without pod apertures, it includes valve body, valve seat, flashboard assembly, valve rod, sealing ring, valve gap, upper sealing, Packing seat with holes, filler, gland, pressing plate, support, gearhead and plug screw, equipped with valve seat and flashboard assembly in the middle of valve body, flashboard assembly is loaded between valve seat, flashboard assembly upper end connects valve rod, valve body upper end equipped with valve gap and between valve body and valve gap equipped with sealing ring, sealing it is sequentially arranged with from the bottom up in valve gap, Packing seat with holes, filler, filler is pressed with gland, gland upper end is pressed with pressing plate, pressing plate two ends are fixed on above valve gap by bolt and nut, equipped with support on valve gap, pedestal upper end is equipped with gearhead, valve body lower end has an osculum, and osculum is equipped with plug screw.
Equipped with bypass valve outside described valve body, bypass valve one end connects valve body import, and the other end connects valve outlet.
Described flashboard assembly is without pod apertures expansion type parallel gate plate assembly.
Described valve seat is hard sealing, and valve seat is welded on valve body, one layer of hard alloy layer of built-up welding on the sealing surface of valve seat.
Keying position indicator it is designed with on described gearhead.
The utility model has the advantages that design is simple, easy to use, solve floating valve seat and easily wear and tear, cause the technical problem of the leakage of valve, meet applying working condition；Valve seat construction: former valve seat soft seal, floating structure；Existing valve seat seals firmly, fixed structure；Flashboard structure: original pod apertures parallel gate plate；It is now without pod apertures expansion type parallel gate plate；
Seal: former soft seal, material is PTFE；Being now hard sealing, material is hard alloy；Increase a mudhole, remove dirt；Increase by one and open and close position indicator, control the stroke of valve opening；Valve seat uses fixed structure, sealing surface weld deposit hard alloy, improves corrosion resistance and the wearability of valve, extends the service life of valve；
Increase a bypass valve, effect be pressure the highest time fast pressure relief, make valve safe and reliable.
