Description

Super large caliber release pollution discharge type one-way sealing gate valve
Technical field
The utility model relates to gate valve field, is specifically related to a kind of super large caliber release pollution discharge type one-way sealing gate valve.
Background technique
Traditional gate valve is the medium connected or block in pipeline.In order to reduce energy consumption, improve generating efficiency, power generating equipment is just towards maximization, high parameter, high-performance future development.
Tradition gate valve adopts the single, double flashboard structure on band inclined-plane, and form the sealing pair on an inclined-plane with valve seat, the lower thrust by valve rod reaches the effect of forced seal.Former gate valve design is two way sealed, single, double flashboard structure, bore less than 40 cun.Existing gate valve design is one-way sealing, Flexible disc structure (Flexible disc structure comprises the advantage of single, double flashboard structure), bore 48 cun of release pollution discharge types.There is shortcoming in it: gate valve bore is large, and release is slow, dangerous and blowdown is inconvenient, so increase release pollutant exhaust hole, one-way sealing, safe and reliable.
Summary of the invention
In order to solve the problem, the utility model proposes a kind of super large caliber release pollution discharge type one-way sealing gate valve, simplicity of design, easy to use, solve the technical problem of super large caliber, release, blowdown, one-way sealing, meet applying working condition.
In order to reach foregoing invention object, the utility model proposes following technological scheme:
Super large caliber release pollution discharge type one-way sealing gate valve, it comprises valve body, valve seat, flashboard, valve rod, upper sealing, filler, gland, valve gap, gearhead, open and close position indicator, pressing plate, support, oil gun, in the middle of valve body, flashboard is housed, between flashboard and valve body, valve seat is housed, flashboard upper end connects valve rod lower end, valve gap is housed in valve body upper end and valve gap is connected to valve body upper end by stud bolt and nut, middle head gasket is housed between valve gap and valve body, inside valve gap upper end and between valve rod, sealing is housed, is pressed with filler above upper sealing, above filler, is pressed with gland, pressing plate is pressed with above gland, pressing plate is fixed on valve gap upper end by swing bolt and nut, and swing bolt lower end is connected to valve gap upper end by straight pin, and valve gap outer upper end is equipped with support, pedestal upper end is equipped with gearhead, keying position indicator is equipped with in gearhead upper end, is arranged on valve rod upper end in the middle of gearhead, and in the middle of valve gap, oil gun is equipped with in outside, side, flashboard lower end has relief hole, and valve body lower end has pollutant exhaust hole and pollutant exhaust hole is equipped with plug screw.
Described super large caliber release pollution discharge type one-way sealing gate valve bore is 48 cun.
The flashboard of described super large caliber release pollution discharge type one-way sealing gate valve is Flexible disc structure, angle 2 ° 52 '.
The utility model has the advantages that bore increases: former less than 40 cun, be now 48 cun; Flashboard structure: former single double-flashboard structure, angle 5 °, volume is large, heavy; Be now Flexible disc structure, angle 2 ° 52 ', volume is little, lightweight; Sealing: former two way sealed is now one-way sealing; Increase pressure relief vent, pollutant exhaust hole, keying position indicator, oil gun; Solve valve sealing face zero seepage, improve the anti-cavitation of flashboard and valve seat and the ability of antiscour, improve overall performance and the working life of valve.
