Description

Check valve extracting tool

Technical field

The utility model is related to a kind of instrument and in particular to a kind of check valve extracting tool.

Background technology

Check valve is easily worn part, and in the course of the work, its waste is very big, thus causing the replacement cost of check valve Too high, and the check valve changing, and non-fully can not use, the gland through measuring a lot of check valves does not wear and tear, sealing Enclose as symmetrical structure, a life cycle will be it is also possible to use by turn-over before sealing, some valve elements also have the value of recycling, then Because the dismounting of check valve is more difficult, there is no special fix tool, traditional method is, by by valve element bench vice card again Live, then pound gland with sledgehammer, this kind of dismounting mode, easily damage miscellaneous part, dismantle very difficult, removal efficiency is low simultaneously.

Utility model content

For problems of the prior art, the purpose of this utility model is that design provides a kind of check valve to dismantle work Tool.

Described check valve extracting tool, it is characterised in that including chuck, handle, described chuck is fixedly installed tubular Connecting post, the inwall of described tubular connecting post is provided with internal thread, and described handle includes outer tube and inner core, described outer tube and cylinder External screw thread with screw-internal thread fit is provided with the outer wall of one end that shape connecting post connects, described inner core is plugged in outer tube, and Slide along outer tube inner wall and arrange.

Described check valve extracting tool is it is characterised in that be provided with through hole on described chuck.

Described check valve extracting tool is it is characterised in that described chuck is arranged for integral type with tubular connecting post.

Described check valve extracting tool is provided with end cap it is characterised in that described inner core stretches out on one end of outer tube.

Described check valve extracting tool is it is characterised in that described outer tube and inner core are hollow structure.

Described check valve extracting tool is it is characterised in that be fixedly installed link on described end cap.

The utility model structure is simple, reasonable in design, by the through hole being arranged on chuck, realizes to check valve gland Card jail, is then rotated to chuck by handle, thus can separate the gland of check valve, valve element and sealing ring easily, keeps away Exempt from miscellaneous part to be caused damage, realize the dismounting to check valve, available unit is reused, save production cost, by hand Handle is arranged to outer tube and the inner core of hollow structure, both can according to circumstances adjust the length of handle, also can place little in inner core Part, convenient use.

Brief description

Fig. 1 is structural representation of the present utility model；

In figure: 1- chuck, 2- tubular connecting post, 3- outer tube, 4- inner core, 5- through hole, 6- end cap, 7- link.

Specific embodiment

To further illustrate the utility model below in conjunction with Figure of description.

As shown in figure 1, the utility model check valve extracting tool, it is mainly used in the dismounting of check valve, including chuck 1, hand Handle, chuck 1 is fixedly installed tubular connecting post 2, and chuck 1 is arranged for integral type with tubular connecting post 2, tubular connecting post 2 Inwall on be provided with internal thread, handle 1 includes outer tube 3 and inner core 4, the outer wall of one end that outer tube 3 is connected with tubular connecting post 2 On be provided with external screw thread with screw-internal thread fit, inner core 4 is plugged in outer tube 3, and slides setting along outer tube 3 inwall.Wherein, block Through hole 5 is provided with disk 1, the concrete structure of through hole 5 Main Basiss check valve gland is configured, due to chuck 1 and handle For threaded setting, therefore, a handle can connect different chucks 1, increases the flexibility ratio using, without different model Check valve is equipped with complete volume extracting tool, it is only necessary to change corresponding chuck 1 during the check valve of dismounting different model, Outer tube 3 and inner core 4 are hollow structure, can place small article, conveniently take at any time, for preventing small article in inner core 4 Drop, end cap 6 is provided with one end that inner core 4 stretches out outer tube 3.For convenience of hanging, end cap 6 is fixedly installed link 7.

The utility model is to block valve element with bench vice to the unloading process of check valve, selects corresponding with check valve gland Chuck 1, chuck 1 is connected by internal and external threads with handle, then adjusts the length of handle as the case may be, by gland In the through hole 5 of chuck 1 in the extracting tool of be aligned corresponding size, after adjusting the position of chuck 1, only need to firmly rotate hand Handle, you can separate valve element, gland, sealing ring, then according to each component wear situation, re-start assembling, realize secondary utilization, This kind of extracting tool, simple to operation, labour intensity is low, efficiency high, saves check valve replacement cost simultaneously.
