Abstract
The utility model discloses a valve core detacher of a large radial sealing check valve. The valve core detacher of the large radial sealing check valve comprises a handle, a screw rod and a nut. The valve core detacher of the large radial sealing check valve is characterized in that the middle portion of the handle is integrally welded with one end of the screw, the other end of the screw is provided with threads, and the nut is matched with the threads of the screw. When the valve core detacher is used, the nut is screwed down from the screw, then the screw is inserted into the valve core, and then the nut is tightly screwed on, the handle of the valve core detacher is held through manpower and pulled out through impact force at the moment, and the shorter pulling-out time is, the larger the impact force is. The valve core detacher of the larger radial sealing check valve has the advantages of being relatively simple and practical, and generally capable of conveniently detaching the valve core without a large mechanism, conveniently replacing a seal ring, and solving the technical problem existing in the prior art of difficult detachment of the valve core.
Description
Technical fieldThe utility model belongs to excavator spool dismantling technology field, is specifically related to a kind of large-scale radial seal inner elements of check valve stripping attachment.
Background technologyThe dismounting of the large-scale radial seal inner elements of check valve of prior art, more solid due to what press between spool and valve piece, and sealing ring is squeezed between spool and valve piece, is difficult to spool is separated with the valve piece, the replacing sealing ring is unusual difficulty also.Up to the present, also do not have good mode to solve this dismounting difficult problem.
Summary of the inventionThe purpose of this utility model is to solve the technical problem that there is the dismounting difficulty in prior art, provides a kind of large-scale radial seal inner elements of check valve stripping attachment, to overcome the deficiencies in the prior art.
A kind of large-scale radial seal inner elements of check valve stripping attachment of the utility model, it comprises handle, screw rod and nut; Its main points are that the middle part of described handle and an end of screw rod are welded as a whole; The other end of described screw rod is provided with screw thread; Described nut matches with screw thread on screw rod.
During use, nut is back-outed from screw rod, then screw rod is inserted spool, then nut is screwed on tightened, hold spool stripping attachment handle with manpower this moment, pulls outward with impulsive force, and impulsive force is larger, and the dial-out time is shorter.The fairly simple practicality of this stripping attachment, without large corporation, general this spool can be for convenience detach, and it is also more convenient to change sealing ring.The utility model has solved prior art and has had the difficult technical problem of dismounting spool dismounting.
Description of drawingsAccompanying drawing is that the utility model uses the state reference view.
In figure 1, handle 2, screw rod 3, nut 4, sealing ring 5, spool 6, valve piece
The specific embodimentWith reference to the accompanying drawings, the utility model it comprise handle 1, screw rod 2 and nut 3; One end of the middle part of described handle 1 and screw rod 2 is welded as a whole; The other end of described screw rod 2 is provided with screw thread; Described nut 3 matches with screw thread on screw rod 2.
The large-scale radial seal inner elements of check valve of the utility model stripping attachment, wherein handle 1 use open circles steel is done, and lighter weight is saved material, grasps also more convenient.Screw rod 2 use filled circles steels are done, and are durable.Handle 1 and screw rod 2 are integrally welded.The screw thread of nut 3 and screw rod 2 is supporting, in use, nut 3 is twisted screws out, and the threaded side of inner elements of check valve stripping attachment is inserted in the hole of spool 5, then nut 3 is screwed in extracting the threaded end of structure from spool 5 inside, and is standby tight.Hold handle 1 with manpower this moment, pulls outward with impulsive force, and impulsive force is larger, and the dial-out time is shorter.The fairly simple practicality of the utility model without large corporation, need not by external force, just can be dismantled the excavator spool easily.
