Abstract
A new type speed joint comprises an outer opening sleeve, a connecting sleeve, a speed joint section of the joint and a valve body section provided in the joint cavity; the connecting sleeve is provided with an inserting pipe, which is sealed and connected in a movable way with inner hole connecting with the head of the joint and the joint cavity; the valve body section comprises a valve core which is provided on its front end with a pipe, a sealing ring provided on the upper end of the valve core, a spring provided on the valve core and the back end of the joint cavity, and a valve port provided on the exit of the joint inner hole. The special place lies in that the valve port is platform shaped, convex rings are provided around the valve port on the platform. The utility model, in comparison with existing technology, has a good sealing effect and invulnerability of the sealing ring.
Description
Technical field:
The utility model relates to a kind of joint, particularly a kind of joint that links together fast.
Background technique:
Existing quick-acting joint, the main valve body part that connects partly and be arranged on the joint inner chamber soon by outer unlatching cover, connecting sleeve, joint, have intubate on the connecting sleeve, intubate sealing is actively socketed on the endoporus that the head of joint communicates with the joint inner chamber, valve body mainly by front end have pipe spool, be arranged on the seal ring of spool upper end, be arranged on the spring of spool and joint intracavity posterior end, the valve that is positioned at the import of joint endoporus constitutes, it is horn-like that valve is.During work, spool is under the promotion of spring, advance toward the joint endoporus, by the seal ring closing valve on the spool, thereby reach the effect of closing the joint valve body, during unlatching, by pushing away valve in the insertion of the intubate on the connecting sleeve endoporus and with spool, thereby valve body is opened, and fast both are sealedly connected.This kind quick-acting joint is owing to be close to the effect that reaches on the horn-like valve to sealing by the seal ring on the spool, therefore seal ring is subjected to the effect of bigger shearing force, and seal ring is damaged easily, and, also easily because of the seal ring assymmetrical deformation, and influence the sealing effect of seal ring.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of good sealing effect, seal ring not to allow flimsy novel quick-acting joint.
The utility model is to realize like this, comprise the outer valve body part that connects partly and be arranged on the joint inner chamber soon of opening cover, connecting sleeve, joint, have intubate on the connecting sleeve, intubate sealing is actively socketed on the endoporus that the head of joint communicates with the joint inner chamber, valve body mainly by front end have pipe spool, be arranged on the seal ring of spool upper end, be arranged on the spring of spool and joint intracavity posterior end, the valve that is positioned at the import of joint endoporus constitutes, its specialization is that valve is platform-like, and valve port is provided with bulge loop in the platform upper edge.During work, spool moves toward valve under the promotion of spring, seal ring is pressed on the bulge loop of valve, because seal ring is to have certain flexiblely, therefore, bulge loop can be imbedded in the seal ring under the effect of pressure, thereby closely with valve seal.Because do not have shearing force between seal ring and bulge loop, therefore, seal ring can not sustain damage.
Here, in order to guarantee the sealing of seal ring, the bulge loop cross section is taper.
Here, on seal ring, be enclosed with copper sheathing.The effect of copper sheathing is the shape that keeps seal ring, avoids it to be out of shape excessive under pressure and forms assymmetrical deformation and then influence its sealability.
Compared with the prior art the utility model has good sealing effect, seal ring is not allowed flimsy advantage.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in the figure, the utility model comprises the outer cover 1 of opening, connecting sleeve 2, the connecing part 3 soon and be arranged on the valve body part 5 of joint inner chamber 4 of joint, have intubate 6 on the connecting sleeve 2, intubate 6 sealing is actively socketed on the endoporus 7 that the head of joint communicates with the joint inner chamber, valve body 5 is mainly had the spool 9 of pipe 8 by front end, be arranged on the seal ring 10 of spool 9 upper ends, be arranged on the spring 12 of spool 9 and joint intracavity posterior end 11, the valve 13 that is positioned at joint endoporus 7 inlets constitutes, its specialization is that valve 13 is platform-like, be provided with bulge loop 15 at platform upper edge valve port 14, bulge loop 15 cross sections are taper.On seal ring 10, be enclosed with copper sheathing 16.
Claims (3)
1, a kind of novel quick-acting joint, comprise the outer valve body part that connects partly and be arranged on the joint inner chamber soon of opening cover, connecting sleeve, joint, have intubate on the connecting sleeve, intubate sealing is actively socketed on the endoporus that the head of joint communicates with the joint inner chamber, valve body mainly by front end have pipe spool, be arranged on the seal ring of spool upper end, be arranged on the spring of spool and joint intracavity posterior end, the valve that is positioned at the import of joint endoporus constitutes, it is characterized in that valve is platform-like, valve port is provided with bulge loop in the platform upper edge.
2, novel quick-acting joint according to claim 1 is characterized in that being enclosed with copper sheathing on seal ring.
3, novel quick-acting joint according to claim 1 is characterized in that the bulge loop cross section is taper.
