Abstract
The utility model discloses a removal tool for a valve seat of a plunger valve. The removal tool comprises a removal pressing plate for being fixed on a plunger valve body and a removal clamping block arranged in a valve seat fluid channel, wherein a shoulder step is in clamping match with a sealing surface of the valve seat is arranged on the removal clamping block, a removal screw is fixedly arranged on the outer lateral surface of the removal clamping block, a shaft hole is formed in the removal pressing plate, the outer end of the removal screw penetrates through the shaft hole, a removal nut is fixedly arranged on a thread at the outer end of the removal screw, and the inner end of the removal nut is matched with the outer end face of the removal pressing plate in a limit abutting against mode. The removal tool for the valve seat of the plunger valve is simple in structure, suitable for removal of the valve seat of the plunger valve, convenient to operate and reliable in operation.
Description
Technical field
The utility model discloses a kind of extracting tool of plunger valve valve seat.
Background technology
Plunger valve is made up of parts such as valve body, valve gap, valve rod, insertion ring, hole frame, plunger, handwheel, YEs, when handwheel rotation (or electric operating), drive plunger in the middle of the frame of hole, to pump the open and close function of valve by valve rod.The opening and closing element of plunger valve is the flap of plug type, also claims plunger, and its sealing surface is taper seat, and plunger is along the center line moving linearly of fluid.
Closing by plunger and valve seat of plunger valve forms, and sealing effectiveness is closely cooperated to reach by plunger and spool.Plunger is slowly mobile in upper and lower insertion ring the inside, and contact-making surface weares and teares hardly, and while closing, plunger inserts in lower insertion ring, blocks runner; When unlatching, although plunger departs from lower insertion ring, but still ensconce in upper insertion ring, keep being isolated from the outside, unlikely leakage.
Reciprocating motion between plunger and valve seat, while cutting off fluid, because there is other impurity in fluid, causes sealing surface of seat to occur wearing and tearing (because of the particularity of plunger material, being that wearing and tearing appear in valve seat substantially).
Need in use for some time plunger valve to carry out air-tight test and maintaining for this reason, to ensure the good air-tightness of plunger valve, but because the particularity of plunger type valve, as shown in Figure 1, this valve seat 2 ' is arranged in the hole frame of valve body 1 ' by interference fit, while causing valve seat to be removed, has difficulties.
Summary of the invention
The purpose of this utility model is the shortcoming and defect existing in order to overcome prior art, and a kind of simple in structure, convenient disassembly, extracting tool with low cost and that can not impact valve body hole frame sealing surface are provided.
For achieving the above object, the technical solution of the utility model is to include for being fixed on the dismounting pressing plate on plunger valve valve body and being arranged at the dismounting clamping block in valve seat fluid passage, on this dismounting clamping block, be provided with the shoulder rank of joining with the sealing surface card of valve seat, on the lateral surface of described dismounting clamping block, be fixedly installed dismantling screw, on described dismounting pressing plate, be provided with axis hole, the outer end of described dismantling screw is through axis hole, and the outer end screw thread of this dismantling screw is fixedly installed dismounting nut, the inner of this dismounting nut coordinates with the spacing withstand effect in outer face of dismounting pressing plate.
By this setting, in the time that needs are dismantled plunger valve valve seat, dismounting clamping block is embedded in the fluid passage in valve seat, and the shoulder rank of this dismounting clamping block are stuck in to the sealing surface place of valve seat, and then twist dismounting nut, drive dismantling screw to move from the fluid passage China and foreign countries of valve seat, and then dismounting clamping block is deviate from together with valve seat in the hole frame of valve body simultaneously, the utility model structure arranges simply, but is but highly suitable for the valve seat dismounting of plunger valve, easy and simple to handle reliable.
Further arrange is the axis direction and the mutual vertical setting of dismounting pressing plate of described dismantling screw.By this setting, make the moving direction of dismantling screw can convert the stroke that shifts out of valve seat to the largelyst, improve removal efficiency.
In sum, the utility model has the advantages that structure arranges simply, be highly suitable for the valve seat dismounting of plunger valve, easy and simple to handle reliable.
Below in conjunction with specification drawings and specific embodiments, the utility model is described further.
Brief description of the drawings
The valve seat of Fig. 1 plunger valve and valve body hole frame assembling schematic diagram;
Fig. 2 the utility model is applied to the structural representation of plunger valve valve seat dismounting.
Detailed description of the invention
Below by embodiment, the utility model is specifically described, only for the utility model is further described, can not be interpreted as the restriction to the utility model protection domain.
Detailed description of the invention of the present utility model as shown in Figure 2, the extracting tool of plunger valve valve seat, include for being fixed on the dismounting pressing plate 4 on plunger valve valve body 1 and being arranged at the dismounting clamping block 2 in valve seat 3 fluid passages, on this dismounting clamping block 2, be provided with the shoulder rank 21 of joining with the sealing surface card of valve seat, on the lateral surface of described dismounting clamping block 2, be fixedly installed dismantling screw 6, on described dismounting pressing plate 4, be provided with axis hole 41, the outer end of described dismantling screw 6 is through axis hole, and the outer end screw thread of this dismantling screw 6 is fixedly installed dismounting nut 5, the inner of this dismounting nut 5 coordinates with the spacing withstand effect in outer face of dismounting pressing plate 4.
As preferred setting, the axis direction of the dismantling screw 6 described in the present embodiment and the mutual vertical setting of dismounting pressing plate 4.
