Description
Technical field
The utility model is related to a kind of orbit ball valve, more particularly, to a kind of service life high and easy-to-dismount track ball
Valve.
Background technology
Orbit ball valve and gate valve are to belong to a valve for type together, and difference is a spheroid in its closure member, and spheroid is around valve
A kind of valve that body center line makees rotation to reach unlatching, close.Ball valve is mainly used to make in pipeline and cuts off, distributes and change
The flow direction of medium.
The characteristics of orbit ball valve is：Orbit ball valve is a kind of novel valve being widely adopted in recent years.In order to reach nothing
The mode of operation of friction, during Open valve, valve rod is lifted first makes valve ball depart from valve seat, and then valve rod drives valve ball to turn to
Open position；When closing valve, valve rod drives valve ball to be rotated in the case where valve seat is not contacted, and then valve rod declines compressing valve ball
It is pressed on valve seat.Ball valve uses the ball valve with fixed pivot axi structure, to ensure fast valve switch, low torque, be easy to out
Open and close.Valve body structure uses roof-mounted design, can be by dismantling valve with the replacing and maintenance that ensure valve internal part
Gate valve lid is repaired online, without valve is disassembled from pipeline.To ensure that it is long-term, lasting that valve has
Tight seal characteristic.Sealing between valve ball and valve seat is realized not against the pressure of medium, it is ensured that the sealing of valve is not received
The influence of pressure medium fluctuation.Valve ball sealing surface and sealing surface of seat ensure the longevity of valve seal body using without friction design
Life.During opening and closing, the sealing surface of valve ball and the sealing surface of valve seat are always ensured that do not connect in operation valve
Touch, it is to avoid phase mutual friction produces to valve ball sealing surface and sealing surface of seat and damages and reduce valve seal performance and service life.
Valve seat is embedded in valve body using the mode that mechanical interference is colded pressing, and does not use welding, and the mode of screw thread or adhesion installs valve seat.Cut-out ball
Valve possesses valve seat and exempts to wash away design.When valve is opened and closed, the circulation passage moment standard-sized sheet or fully closed of stop valve makes valve
Without high-velocity fluid local erosion sealing surface of seat in switching process, so as to further improve the sealing life of valve.Valve ball is close
Front cover uses carbide alloy of nickel-base, Hastelloy or other alloy welding deposits, and built-up welding minimum thickness is not less than 1.5mm, to ensure valve
Tightness and permanent sealing life of the door in most harsh operating mode lower valve.Valve possesses bi-directional sealing capabilities, can bear double
To pressure difference.The refractory design of valve performs the standard of API 6FA and API 607.All of valve is all fire safe.
Flexible graphite packing is provided with orbit ball valve stuffing-box, effect can be lost because of reasons such as fire in other fillers
When flexible graphite packing play sealing effectiveness；Fire resistant requirements can be met, but it is real in emergency, find flexible filler
Need in time, often to miss optimal Sealing period, finally lead to big loss.
Chinese patent CN203656356U discloses a kind of orbit ball valve, including valve body, valve seat, base, spheroid, valve rod,
It is filler seat, bonnet, sealing ring, filler, gland, hold-down grid, guide finger, valve stem nut, bearing gland, shield, indicating arm, anti-
Konisphere and threaded connection inject annex with the filler on bonnet, and filler injection annex includes injection attachment body, injects annex sheet
Body is the hollow hollow bolt of axis direction, is filled out in injection attachment body and is provided with soft graphite, and injection attachment body internal thread connects
Bolt is connected to, bolt leading portion is fixedly connected with push pedal, and push pedal is slidably connected with injection attachment body inner wall sealing.It can pass through
Bolt is screwed on injection annex to obtain, flexible graphite packing is quickly inserted, to reach the effect of fast sealing, but the track ball
The guide finger of valve is provided on bonnet, when needing to dismantle guide finger or change, and need to be dismantled bonnet, and it changes fiber crops
It is tired, while its service life is relatively low.
