Description

Quick coupler plug valve rod

Technical field

It the utility model is related to a kind of attachment means of fast assembling-disassembling, especially quick coupler plug valve rod.

Background technology

Snap joint includes hydraulic quick coupling and various fluid quick joints, and it is a kind of quick connection or off-tube Road, realize the attachment means of fast assembling-disassembling.Because there is dual check function pipeline to disconnect No leakage for snap joint, therefore in stone Oil, metallurgy, water power, engineering machinery, ship, electromechanical equipment etc. are widely used in field.Connecting structure for quick coupling is The most important part of snap joint, its connected mode and structure directly determine the ease of use of snap joint, reliability And product quality.Snap joint is made up of public plug and mother socket two parts, and public plug and mother socket include valve arrangement, common Valve arrangement is more simple, and plug valve element and housing valve element push opening runner, and runner can not simply form the loop of circulation, run into Special circumstances, it can not also complete not shutdown operation, it is therefore desirable to rational valve arrangement, it is ensured that smooth butt joint when switching on and off Inner structure has no adverse effects, and avoids damaging joint.

The content of the invention

In order to solve the technical problem in the above-mentioned loop that can not form circulation, the utility model provides quick coupler and used Plug valve rod.

The technical solution of the utility model is as follows：

Quick coupler plug valve rod, including plug stem body, plug stem body include annular solid E and annular Body F, annular solid E and annular solid F are formed in one, and annular solid F rear ends outer wall outwardly convex forms torus B, and torus B is horizontal Through having through hole D, plug stem body rear and front end opening, plug stem body inner hollow forms passage A, the annular solid E front inner walls extend inwardly to form bayonet socket A.

The corner recess of torus B front ends outer wall one, it is horizontally disposed that the inwall on the inside of bayonet socket A, which has two sections, and radius is from small To big, length is from being short to length.

Plug valve rod inner ring is arranged with the plug stem body, hole is provided with the middle part of plug valve rod inner ring.

Using the technical solution of the utility model, the design of new type of valve, the impact of high-velocity fluid and pulse can be resisted, Higher performance is provided；Fabricated using single solid steel bar, so durability is good；Plug valve rod is not only medium in mother socket The critical piece of circulation, and the part that backflow needs pass through, are designed with loop, and pressure source can not shutdown operation, directly general Public plug inserts mother socket, is attached and disconnects, can self pressure release, proof pressure is high, and butt joint inner structure has no adverse effects, Avoid damaging joint；Novel flow channel designs, and operating pressure runner is resistant to 70MPa high pressures, and medium loop runner is resistant to 10MPa pressure Power.

Brief description of the drawings

Fig. 1,2 are structural representations of the present utility model；

Fig. 3,4,5 are the structural representations of the utility model embodiment.

Embodiment

The utility model is described in further detail with reference to the accompanying drawings and examples.

Embodiment

Quick coupler plug valve rod as shown in Fig. 1,2,3,4,5, including plug stem body 3, plug valve rod Main body 3 includes annular solid E60 and annular solid F61, and annular solid E60 and annular solid F61 are formed in one, outside annular solid F61 rear ends Wall outwardly convex forms torus B, and torus B levels, which run through, through hole D59, the rear and front end opening of plug stem body 3, plug The inner hollow of stem body 3 forms passage A57, and the annular solid E60 front inner walls extend inwardly to form bayonet socket A58.Plug 1 Inwall is provided with the breach to clamping rings body B, and installation is firm.Backflow can be completed, public plug and mother socket are required for can be complete Into the valve arrangement of backflow, and plug valve rod is not only the critical piece of flow of media in public plug, and backflow needs what is passed through Part, mainly there is gap by through hole D59, plug 1 and the outer wall of plug stem body 3, be easy to backflow to use.

The corner recess of torus B front ends outer wall one, the inwall on the inside of bayonet socket A58 have two sections be it is horizontally disposed, radius from It is small to big, length is from being short to length.

Plug valve rod inner ring 4 is arranged with the plug stem body 3, plug valve element is arranged with plug valve rod inner ring 4 Valve pocket 6, the middle part of plug valve rod inner ring 4 are provided with hole, increase width of flow path, the rear portion of plug valve element inner ring bar 5 and plug valve rod inner ring 4 Between leave space.

In use, in the 27 anterior utensil receiving opening between housing 22 of the axial-rotation of plug 1 insertion housing valve pocket, dop 32 is inserted Enter in helicla flute, the front portion of housing valve pocket 27 is inserted into the space between plug 1 and plug stem body 3, and plug bushing 2 is shifted onto The rear portion of plug 1, plug bushing spring 12 are compressed, and plug stem body 3 is inserted between housing valve pocket 27 and housing valve seat 29 Space, shift the related case bushing seat 25 of case bushing 24 and case bushing inner ring 26 onto the rear portion of housing valve pocket 27, housing valve Sleeve spring 28 is compressed, and now medium loop runner is got through, meanwhile, housing valve seat 29 is inserted into plug stem body 3, will be inserted Head spool valve pocket 6 and plug valve element inner ring bar 5 shift the rear portion of plug valve element inner ring 4 onto, and plug valve core spring 13 is compressed, housing lining Moved after set inner ring 26, the anterior through hole of housing valve seat 29 is opened, and middle through-hole is blocked, plug valve element valve pocket 6 and plug The caused gap through hole anterior with housing valve seat 29 is connected between valve element inner ring 4, and now operating pressure runner is got through, and is exited When, case bushing inner ring 26 moves forward, and the anterior through hole of housing valve seat 29 is blocked, and middle through-hole is opened, residual medium warp Cross middle through-hole and be back to medium loop runner, reach the purpose of self pressure release.P runners are operating pressure runner, are resistant to 70MPa High pressure, T runners are medium loop runner, are resistant to 10MPa pressure, and female joint designs, pressure under logical pressure condition with loop Source can not shutdown operation, now pressure medium enter from mother socket P ends, by the inner flow passage of housing valve seat 29 from housing valve seat 29 Middle through-hole flows out, and by the space between housing valve seat 29 and housing valve pocket 27, is back to mother socket T ends, public plug is used for Pressure instrument, obstructed pressure before insertion are used in connection；Under male and female off-state, male and female joint two-port P and T connect fluid pipe fitting respectively. If public plug inserts, with the distance of the stroke of plug 1, public plug P ends and T ends are opened, and mother socket P ends disconnect straight-through mother socket T ends, pressure passes through public plug P ends from mother socket P ends, and is back to mother socket T ends from public plug T ends.
