Abstract
The utility model flap type assembling handle, comprise nut, pressure cap, round nut, steel pipe, pull bar, resilient sleeve, cone, it is characterized in that, described nut and pressure cap are located at the top of pull bar successively, described round nut is located at the side of pull bar, described resilient sleeve is connected with pressure cap by steel pipe, and described cone is located at the bottom of pull bar.Compared with prior art, advantage of the present utility model is, does not directly contact in assembling process with valve plate with the sealing surface of valve seat, can not scratch sealing surface, convenient to use, is easy to operation.
Description
Technical field
A kind of handle of the utility model design, specifically a kind of flap type assembling handle.
Background technology
The valve seat of flap type, valve plate and wavy spring are that two valve seats and valve plate are fit together by the elastic force of self by two wavy springs closely in assembling process, and flap type is sealed.So need a flap type assembling handle to make wavy spring compression under the effect of external force, and then valve plate, valve seat is allowed to assemble successfully.The flap type assembling handle of present routine has following two shortcomings: 1, easily the sealing surface of valve plate and valve seat is scratched in operation, have influence on the sealing property of flap type; 2, conventional flap type assembly tool operation is easy not, and operating efficiency is not high.
Summary of the invention
The purpose of this utility model is to solve in prior art, assembling handle, easily the sealing surface of valve plate and valve seat being scratched in operation, has influence on the sealing property of flap type, easy not, the defect that operating efficiency is not high, provides a kind of flap type to assemble handle and solves the problems referred to above.
To achieve these goals, the technical solution of the utility model is as follows: flap type assembling handle, comprise nut, pressure cap, round nut, steel pipe, pull bar, resilient sleeve, cone, described nut and pressure cap are located at the top of pull bar successively, described round nut is located at the side of pull bar, described resilient sleeve is connected with pressure cap by steel pipe, and described cone is located at the bottom of pull bar.
Described pressure cap and steel pipe are for being threaded.
Described resilient sleeve and steel pipe are for being threaded.
Compared with prior art, advantage of the present utility model is, does not directly contact in assembling process with valve plate with the sealing surface of valve seat, can not scratch sealing surface, convenient to use, is easy to operation.
Accompanying drawing explanation
Fig. 1 is the utility model tubing string ratchet wrench structure plane.
In figure, 1. nut; 2. pressure cap; 3. round nut; 4. steel pipe; 5. pull bar; 6. resilient sleeve; 7. cone.
Detailed description of the invention
For making to have a better understanding and awareness architectural feature of the present utility model and effect of reaching, coordinating detailed description in order to preferred embodiment and accompanying drawing, being described as follows:
As shown in Figure 1, flap type assembling handle, comprise nut 1, pressure cap 2, round nut 3, steel pipe 4, pull bar 5, resilient sleeve 6, cone 7, nut 1 and pressure cap 2 are located at the top of pull bar 5 successively, round nut 2 is located at the side of pull bar 5, resilient sleeve 6 is connected with pressure cap 2 by steel pipe 4, and cone 7 is located at the bottom of pull bar 5.Pressure cap 2 and steel pipe 4 are for being threaded.Resilient sleeve 6 and steel pipe 4 are for being threaded.
When using flap type assembling handle, first the nut 1 by tightening assembling handle makes resilient sleeve 6 along the circumferential direction expand to stick in the groove of valve seat endoporus, then tightening round nut 3 makes valve seat along the outside compressed waveform spring of Impact direction, and such valve plate just can successful installation smoothly.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; the just principle of the present utility model described in above-described embodiment and description; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall in claimed scope of the present utility model.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
