Abstract
The utility model discloses a fixture for machining a one-way valve of a general shaft pump. The fixture comprises a die sleeve and a core rod which is used for downwardly pushing a one-way valve shooting ball along the die sleeve. The die sleeve comprises an inner hole used for inserting the core rod conveniently. The diameter of the inner hole is longer than or equal to the diameter of the one-way valve shooting ball. The inner hole comprises a one-way valve sleeve section which is in fit with the outer wall of the upper portion of a one-way valve base. When the fixture is used, the die sleeve is arranged on the one-way valve base in a sleeved mode, the one-way valve shooting ball is placed in the inner hole of the die sleeve, then the core rod is inserted in the inner hole of the die sleeve, the one-way valve shooting ball is pushed downwardly, and then force is all applied to the one-way valve shooting ball attached to the one-way valve base. Through the method, the one-way valve shooting ball completely contacts the attaching surface of the one-way valve base. The fixture for machining the one-way valve of the general shaft pump has the advantages of being simple in structure, low in cost, simple and convenient to operate, high in efficiency and the like.
Description
Technical field
The utility model relates to a kind of fixture, is used for the processing of coaxial pump check valve.
Background technology
The main function of check valve is the one-way flow function.On coaxial pump, its part major part of repairing check valve by oneself processing, so some check valve can cause hoodle and base faying face imprecision in advance, produces and reveals, thereby cause pressure inadequate.
Therefore need a sleeve clamp, make this check valve hoodle fit tight with base.
The utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of coaxial pump check valve fixture for processing, makes this check valve hoodle fit tight with base.
To achieve these goals, the technical solution of the utility model is as follows:
Coaxial pump check valve fixture for processing, it is characterized in that, the plug that comprises die sleeve and be used for the check valve hoodle is promoted downwards along die sleeve, described die sleeve comprises that one is convenient to the endoporus that plug inserts, the aperture of this endoporus is more than or equal to the diameter of check valve hoodle, described endoporus comprise one section with the suitable check valve suit section of check valve base external wall of upper portion.
In a preferred embodiment of the present utility model, the lower end of described plug comprises an inclined-plane that matches with check valve hoodle cylindrical.
During use, die sleeve is enclosed within on the check valve base, puts into the check valve hoodle in the endoporus of die sleeve, then plug is inserted in the endoporus of die sleeve, promote the check valve hoodle downwards, power all is applied on the hoodle of fitting with the check valve base.By the method, check valve hoodle and the comprehensive engagement of check valve base binding face.
The utlity model has simple in structure, cost is low, and is easy and simple to handle, the efficient advantages of higher.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better embodiment of this case and be obtained to be well understood to.

Fig. 1 is use state diagram of the present utility model.
Fig. 2 is the schematic diagram of die sleeve.
Fig. 3 is the schematic diagram of plug.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, further set forth the utility model below in conjunction with specific embodiment.
Referring to Fig. 1,2 and 3, coaxial pump check valve fixture for processing, the plug 20 that comprises die sleeve 10 and be used for the check valve hoodle is promoted downwards along die sleeve.Die sleeve comprises that one is convenient to the endoporus 11 that plug inserts, and the aperture of this endoporus is more than or equal to the diameter of check valve hoodle 30, endoporus comprise one section with the suitable check valve suit of check valve base external wall of upper portion sections 12.The lower end of plug comprises an inclined-plane 21 that matches with check valve hoodle cylindrical.
During use, die sleeve 10 is enclosed within on check valve base 40, puts into check valve hoodle 30 in the endoporus of die sleeve, then plug 20 is inserted in the endoporus of die sleeve, promote check valve hoodle 30 downwards, power all is applied on the hoodle of fitting with the check valve base.By the method, check valve hoodle and 41 comprehensive engagements of check valve base binding face.
Above demonstration and described basic 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; what describe in above-described embodiment and specification is principle of the present utility model; the utility model also has the changes and improvements of various operating conditions under the prerequisite that does not break away from the utility model spirit and scope, 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.
