Abstract
The utility model relates to a kind of extractor for valve pocket.There is a lot of inconvenience in the dismounting at present for valve pocket, valve pocket is difficult to take out after loading housing.The utility model provides a kind of extractor that can be easy to be taken out from housing by valve pocket, solves external diameter and the problem being difficult in the valve pocket loading housing bore of O-ring seal take out is housed.
Description
Technical field
The utility model relates to a kind of extraction element, especially for the extractor of valve pocket.
Background technology
There is a lot of inconvenience in the dismounting at present for valve pocket.Fig. 1 is the installation diagram after external diameter is equipped with the valve pocket loading housing of sealing ring, and in order to ensure sealing, will have the magnitude of interference of more than 0.5mm between usual sealing ring and housing bore, therefore valve pocket is difficult to take out after loading housing.
Summary of the invention
A kind of valve pocket extractor, be made up of elastic expanding pawl, push rod, packing ring, nut, handle and pin, described elastic expanding pawl inner chamber and push rod adopt and are threaded, and the termination of elastic expanding pawl has 3 to 4 uniform isometric wide grooves, and the termination of push rod is the conical surface of 30 ° to 60 ° with cone angle; Outside described elastic expanding pawl and and nut adopt be threaded, pin is arranged on push rod top, described handle and described elastic expanding pawl fastening; Under free state, the external diameter of elastic expanding pawl is less than valve pocket aperture, and elastic expanding pawl is put into valve pocket hole, and packing ring and housing bore end face are fitted, and rotate pin and push rod is moved downward with screw thread, elastic expanding pawl and valve pocket hole wall fit tightly; Rotating nut, takes out valve pocket from housing.
The extractor that the utility model provides can be easy to valve pocket to take out from housing, solves external diameter and the problem being difficult in the valve pocket loading housing bore of O-ring seal take out is housed.
Accompanying drawing explanation
Fig. 1 is the installation diagram after external diameter is equipped with the valve pocket loading housing of sealing ring;
Fig. 2 is the stereogram of the utility model extractor;
Fig. 3 is the profile of the utility model extractor central cross-section vertically;
Fig. 4 is the elastic expanding pawl of extractor;
Fig. 5 is the push rod of extractor.
Detailed description of the invention
As shown in Figures 2 and 3, extractor is made up of elastic expanding pawl 1, push rod 2, packing ring 3, nut 4, handle 5 and pin 6.Elastic expanding pawl 1 and push rod 2 adopt and are threaded, and the termination of elastic expanding pawl 1 has 3 to 4 uniform isometric wide grooves (as Fig. 4), and the termination of push rod 2 is the conical surface (as Fig. 5) of 30 ° to 60 ° with cone angle.Elastic expanding pawl 1 is put into valve pocket hole (under free state, the external diameter of elastic expanding pawl 1 is less than valve pocket aperture), packing ring 3 and housing bore end face are fitted, rotating pin 6 makes push rod 2 move downward with screw thread, when push rod 1 moves downward with screw thread, the conical surface of its termination can make elastic expanding pawl 1 spreading, thus making elastic expanding pawl 1 and valve pocket hole wall fit tightly generation frictional force, the larger frictional force of elastic expanding pawl 1 spreading is larger.When push rod 2 is difficult to move downward again, illustrate that the spreading degree of elastic expanding pawl 1 is close to the limit, now rotating nut 4, elastic expanding pawl 1 is moved upward along with screw thread, under the effect of frictional force, valve pocket can move up together along with elastic expanding pawl 1, thus is taken out from housing by valve pocket.
