Abstract
The invention provides a high-pressure flat gate valve seat extractor. The high-pressure flat gate valve seat extractor comprises a drawing bar, a hook mechanism and a push-and-pull mechanism. The hook end of the drawing bar is in screwed connection with the hook mechanism. The push-and-pull end of the drawing bar is movably connected with the push-and-pull mechanism. The high-pressure flat gate valve seat extractor has the advantages and beneficial effects that the contact area between a reverse arm and a valve seat process tank is increased, and the force bearing area is much larger than that when a copper bar is used for tapping. The drawing bar is driven by a T-nut to move, so that force is larger and more uniform. By adoption of the high-pressure flat gate valve seat extractor, a valve seat can be both extracted and installed. After the high-pressure flat gate valve seat extractor is invented and developed, during extraction and use of 30 valve seats of 15 high-pressure flat gate valves needing maintenance, the extraction success rate is 100%; the extraction time for each valve seat is 15-20 minutes; and the working efficiency by adoption of the extractor is 3-4 times higher than that of a copper bar manual extraction method.
Description
Technical field
The invention belongs to valve field, especially relates to a kind of high-pressure flat gate valve valve seat extractor.
Background technology
High-pressure flat gate valve is a kind of closure member (flashboard) along the valve that moves of vertical line direction of medium channel centrage.Often
For using on oil exploration, oil-gas transportation, chemical industry equipment, it is particularly suited for the water higher to operating pressure, oil, mud, sky
So gas pipeline is made to control the carrying out of media flow to open and close and adjust.High-pressure flat gate valve first passes through sealing surface equal surfacing hard and closes
Gold, makes floating flashboard and valve seat can guarantee that sealing surface fits tightly.Secondly, gate valve can realize entrance point or port of export sealing.
Finally, the rubber seal between valve seat and valve seat orifice, further increases the effect of sealing.But, high-pressure flat gate valve exists
The resistance rotating the opening and closing of operated by handwheel flashboard leading to that can not be floated using the valve seat yet suffering from gate valve after a period of time is increased
Big and ram seal sternly not can't help doing the problem of pressure.Valve seat is caused to have three the reason can not floating：First, and valve seat orifice between
Corrosion or foreign body obstruction；Second, being blocked by impurity in spring groove.Third, the sealing ring on valve seat damages.So, periodically to height
The seal member of locating back gate valve is keeped in repair and maintenance is requisite.The method for dismounting of traditional valve seat is：Removing lock
After plate, gradually impacted along valve seat mounting process groove circumferencial direction using copper rod and exit valve seat orifice to valve seat.Outer ring due to valve seat
There is withered mud and anvil cinder causes valve seat and takes out, the in addition position of copper rod impact more with the time and valve seat orifice between
Stress point is less easily to be trained off valve seat, needs firmly equably symmetrical impact just easily to realize, one hour normal conditions used time
Just take next valve seat, then sealing ring could be maintained and safeguard.Lead to inefficiency, when wasting substantial amounts of
Between, man power and material's cost.
Content of the invention
The invention problem to be solved is to manufacture a kind of convenient dismounting, the device of installation high-pressure flat plate valve base, with
It is easy to maintaining valve seat insert and disk spring with matching, reach and solve the problems, such as that valve seat can not normally float.
For reaching the purpose solving above-mentioned technical problem, the technical scheme that the invention adopts includes drawing bar, hook takes
Mechanism and push-pull mechanism, the hook of described drawing bar takes end to pass through screwed connection, the push-and-pull end of drawing bar and push-and-pull with Gou Qu mechanism
Mechanism is removable to be dynamically connected.
Further, described push-pull mechanism includes handwheel, thrust bearing, fixed support, fixing bolt, push-pull mechanism fulcrum prop up
Frame and feather key, the flange of high-pressure flat plate valve is by affixed with described push-pull mechanism fulcrum support with described fixing bolt, described
Push-pull mechanism fulcrum support is removable with drawing bar to be dynamically connected, and described handwheel is affixed with T-nut, and T-nut passes through thrust bearing
Handwheel radial rotary power is changed to axial force, does axis direction motion, fixed support and thrust bearing under the influence of feather key
Affixed.
Further, described Gou Qu mechanism includes interior pawl, spring, fulcrum support frame and locking bucket, and described interior pawl has one end and is
The working end other end is adjustment end, and the adjustment end of described interior pawl is arranged on inside the bare terminal end of locking bucket, the bare terminal end of locking bucket
The internal taper of inner side is 5-20 degree, and the adjustment end of described locking bucket and drawing bar carry out screwed connection, the end setting of drawing bar
Fulcrum support frame, the angle shape that interior pawl and drawing bar arrange 5-20 degree is in male-tapered, rotational lock bucket change its with interior pawl away from
From adjustment, thus the angle that in adjustment, the working end hook of pawl takes or unclamps.
Further, affixed locking bucket adjusting lever on described drawing bar, described locking bucket adjustment rod outer surface setting and locking
The screw thread that the adjustment end of bucket is adapted.
Further, the inner side of described interior pawl working end is sequentially connected by spring.
Further, described interior pawl working end is circular arc.
The invention has the advantages and positive effects that：
1st, technology groove 70% area in disposable contact valve seat, lifting surface area is bigger than point when only being impacted using copper rod
Much.
2nd, drawing bar is movement under the driving of T-shaped button nut, and strength is bigger and uniform.
3rd, the invention not only can be taken off valve seat but also can be installed valve seat.
4th, after the invention is succeeded in developing, make in the taking-up of 30 valve seats of 15 high-pressure flat gate valves needing maintenance
With in, take out success rate 100%；Every valve seat takes out used time 15-20 minute；The method that this extractor is relatively taken by hand using copper rod
Compare work efficiency and improve 3-4 times.
