Abstract
A quick joint, which comprises a joint with a valve body, and a joint sleeve, characterized in that: the nut of the joint is a circular ring which is provided with one or more than one notch; the utility model is provided with a sealing ring which positions a spring that drives the spool of the joint valve body to shut down; the sealing ring is provided with a packing washer at one end and a snap ring on the face of the other end; a clip spring groove is arranged inside in the inner hole at one end of the joint which corresponds to the snap ring; a clip spring is positioned in the clip spring groove; the sealing ring is fixed on the inner hole of the joint end by the clip spring. Compared with the prior art, the utility model has the advantages that: the quick joint can prevent common people without professional trainings or special authorization from using ordinary tools to operate the connection of gas pipelines, which can cause extreme dangers; besides, when the joint is screwed on the outlet of the gas tank, the sealing ring cannot be unscrewed and loosened from the joint.
Description
Technical field:
The utility model relates to a kind of assembling pipe joint, particularly a kind of quick-acting joint.
Background technique:
The existing quick-acting joint that is used to connect gas can and fuel tube mainly is made of the joint that has valve body, connecting sleeve, joint sealing is screwed in the gas can outlet, connecting sleeve and gas can link together, during use, connecting sleeve is socketed on the joint, by the intubate in the connecting sleeve valve body in the joint is opened, thus the effect that realization connects soon.The joint of this kind quick-acting joint is by being arranged in the outlet that hexagon nut on the joint is screwed in gas can, does not have through the general people of professional training or special permission as long as just joint can be screwed in the gas can outlet with general instrument to export upward or from gas can and take off joint and carry out bringing the gas pipeline attended operation that is in extreme danger; In addition, the location of the spring that drive joint valve body spool is closed is to finish by the seal ring that has seal washer that is threaded in the joint end, joint is screwed in the gas can exit procedure, seal ring looses from the joint rotation under the effect of the power of spinning easily, thereby influenced normal operation, also influenced joint simultaneously and be screwed in the sealing that gas can exports.
Summary of the invention:
Goal of the invention of the present utility model is to provide a kind of gas pipeline attended operation that can prevent from not have the general instrument of general human through professional training or special permission to carry out bringing to be in extreme danger, the quick-acting joint that seal ring can not loose from the joint rotation when joint was screwed in the gas can outlet.
The utility model is achieved in that and comprises that joint, the connecting sleeve that has valve body, its specialization are that the nut on the joint is an annulus that annulus is provided with one or more bayonet socket.During use, because the nut on the joint is one to have the annulus of bayonet socket, not having the general instrument of general human through professional training or special permission is joint can not be screwed in that the gas can outlet is gone up or take off joint from the gas can outlet and carry out bringing the gas pipeline attended operation that is in extreme danger, can only be that professional human special tool(s) through professional training or special permission could be screwed in joint the gas can outlet and goes up or take off joint from the gas can outlet and carry out bringing the gas pipeline attended operation that is in extreme danger.
Here, the seal ring end face that drives spring location that joint valve body spool closes and the end has a seal washer is provided with snap ring, the joint termination endoporus of corresponding snap ring is provided with the jump ring groove, and the jump ring groove is provided with jump ring, and seal ring is fixed on the endoporus of joint termination by jump ring.Like this, because seal ring is not that screw thread is fixed on the joint termination, therefore, seal ring can not loose from the joint rotation under the effect of the power of spinning.
Here, the joint valve body mainly by the cross section be the T font spool, be arranged on the valve in the joint, the seal ring that is arranged on the T font seal spool montant constitutes, valve is a pipeline that matches with the seal spool montant, the seal spool montant is the pipe of a hollow, and the sidewall of pipe is provided with the perforation that communicates with pore near T font top.During work, the seal spool montant gos deep in the valve and by the seal ring on the sealing montant valve seal cutting out under the effect of spring, after connecting connecting sleeve, intubate on the connecting sleeve pushes away valve with the seal spool montant, and the gas that comes from joint enters in the intubate on the connecting sleeve and by on the conduit that intubate enters with connecting sleeve communicates gas delivery being gone out by perforation, pore.Because after valve body was closed, under the effect of gas atmosphere, hermetically closing was on valve firmly for spool in joint, therefore, valve mechanism has simple in structure.
The utility model compared with the prior art, have the general instrument of general human that can prevent from not have through professional training or special permission and carry out to bring the gas pipeline attended operation that is in extreme danger, safety, seal ring can not rotate the advantage that looses from joint when joint was screwed in the gas can outlet.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the cross sectional view of joint;
Fig. 3 is the structural representation of spool.
Embodiment:
Now in conjunction with the accompanying drawings and embodiments the utility model is described in further detail:
As shown in Figure 1, the utility model comprises joint 1, the connecting sleeve 2 that has valve body, its specialization is that the nut 3 on the joint 1 is an annulus, annulus 3 is provided with one or more bayonet socket 4, as shown in Figure 1 and Figure 2, seal ring 8 end faces that drive spring 6 location that joint 1 valve body spool 5 closes and the end has a seal washer 7 are provided with snap ring 9, the joint 1 termination endoporus 10 of corresponding snap ring 9 is provided with jump ring groove 11, jump ring groove 11 is provided with jump ring 12, and seal ring 8 is fixed on the joint termination endoporus 10 by jump ring 12.
The joint valve body mainly by the cross section be the T font spool 5, be arranged on the valve 13 in the joint 1, the seal ring 15 that is arranged on the T font spool 5 sealing montants 14 constitutes, valve 13 is a pipeline that matches with seal spool montant 14, seal spool montant 14 is the pipe of a hollow, and the sidewall of pipe is provided with the perforation 17 that communicates with pore 16 near T font top.
