Abstract
The utility model provides a pressure measurement joint. The pressure measurement joint comprises a joint cavity, a dust-proof cap, a dust-proof core, and a self-sealing valve core part arranged in the joint cavity, wherein the self-sealing valve part comprises a valve core arranged in the cavity body of the joint cavity, a spring is arranged on the lower part of the valve core, a tightly topping body composed of a first insert block and a second insert block is arranged on the upper part of the valve core, the dust-proof core is arranged on the top of the joint cavity, and the dust-proof core and the joint cavity are muff-coupled in the dust-proof cap. By using the above design, the pressure measurement joint is at the self-sealing state under the action of the spring inside, and any leakage phenomenon does not occurs; the pressure measurement joint is connected and disconnected with a measurement hose only by hands at high pressure; the pressure measurement joint is conveniently connected with a test instrument, the working pressure and sealing performance are obviously improved, the structure is compact and easy to realize.
Description
Technical field
The utility model relates to a kind of pressure measuring tie-in, specifically relates to a kind of hydraulic joint for sampling and system pressure test.
Background technology
Along with the progress of society, it is more and more general that hydraulic technique is used, for the sampling of fluid system and the test of system pressure, and pressure measuring tie-in one of the element that is absolutely necessary, it and pressure measurement flexible pipe and tensimeter are combined, and test the pressure of each spot pressure.The pressure measurement flexible pipe connects pressure measuring tie-in and tensimeter, and the pressure in the hydraulic system is passed to tensimeter by pressure measurement flexible pipe and pressure measuring tie-in, just can accurately read the pressure of each spot pressure.Self-sealing valve is arranged in the pressure measuring tie-in, and owing to the effect of spring, Self-sealing valve is closed when using separately; After connecting with the pressure measurement flexible pipe of thimble and downhole joint, Self-sealing valve is opened, and uses easily.
Existing hydraulic joint as shown in Figure 1, pressure measuring tie-in spool and joint cavity are being threaded connection separately, seal with zero type circle.Steel ball and spring are arranged in the spool, realize the auto-lock function of pressure measuring tie-in.But this joint exists zero type circle of complex structure, the loaded down with trivial details and sealing of assembling in inside, changes the large defective of difficulty; And the dustproof core of existing pressure measuring tie-in is connected to the outside of dust cap mostly, and poor sealing performance, easy to leak directly affect manometric reading.
The utility model content
The purpose of this utility model provides a kind of pressure measuring tie-in, solve that existing hydraulic joint complex structure, poor sealing performance, assembling are loaded down with trivial details, zero type circle of sealing inner, change the large problem of difficulty.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of pressure measuring tie-in, comprise joint cavity, dust cap, dustproof core and be arranged on Self-sealing valve core segment in the joint cavity, be characterised in that: described Self-sealing valve core segment comprises the spool in the cavity that is arranged on the joint cavity, described spool bottom is provided with spring, described spool top be provided with by first insert, the second body that holds out against of inserting and forming, described dustproof core is arranged on the top of joint cavity, and described dustproof core and joint cavity are socketed in the dust cap.
Be provided with the one zero type circle between described joint cavity and the dust cap.
Described first inserts and second is provided with the 20 type circle between inserting.
Described first insert and spool between be provided with the 30 type circle.
Connect the first chaining sheet on the described joint cavity, connect the second chaining sheet on the described dustproof core, between described the first chaining sheet and the second chaining sheet chaining is set.
The beneficial effects of the utility model: owing to adopt above-mentioned joint cavity, dust cap, the dustproof core of comprising, and the pressure measuring tie-in design that is arranged on the Self-sealing valve core segment in the joint cavity, pressure measuring tie-in is in self-enclosed state under interior effect of establishing spring, any Seepage can not occur; Under high pressure only can finish with combination and the disconnection of measuring flexible pipe with hand; Itself and test instrumentation are easy to connect, can obviously improve working pressure and sealing property, and structure is small and exquisite, are easy to realize.
Below with reference to drawings and Examples, the utility model is described in detail.
Description of drawings
Fig. 1 is the organigram of pressure measuring tie-in of the prior art.
Fig. 2 is organigram of the present utility model.
Among the figure: the 1.ED rubber cushion, 2. spring, 3. the one zero type circle, 4. dust cap, 5. spool, 6. the 30 type circle, 7. first insert, 8. the 20 type circle, 9. second insert, 10. dustproof core, 11. joint cavitys, 12. first chaining sheets, 13. chainings, 14. second chaining sheets, 15. steel balls.
Embodiment
As shown in Figure 1, the spool 5 of existing pressure measuring tie-in Self-sealing valve core segment is connected with the joint cavity by separately connection of screw thread, seal with zero type circle, realize the auto-lock function of pressure measuring tie-in by steel ball 15 and spring 2, but this complex structure, assemble loaded down with trivial detailsly, zero type circle of sealing is section within it; The replacing difficulty is large, and dustproof core 10 is connected to the outside of dust cap 4 in addition, and poor sealing performance, easy to leak directly affect manometric reading.
The nipple tip of described joint cavity 11 bottoms is provided with ED rubber cushion 1.
Be provided with the one zero type circle 3 between described joint cavity 11 and the dust cap 4.
Described first inserts 7 and second inserts and is provided with the 20 type circle 8 between 9.
Described first insert 7 and spool 5 between be provided with the 30 type circle 6.
Connect the first chaining sheet 12 on the described joint cavity 11, connect the second chaining sheet 14 on the described dustproof core 10, between described the first chaining sheet 12 and the second chaining sheet 14 chaining 13 is set.
Above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineering technical personnel in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
