Abstract
The invention discloses a double-sealed rapid joint which comprises a female connector and a male connector. The female connector comprises a plug bush (1) body, wherein the plug bush (1) is internally provided with a valve core (4) and a valve seat (3) with an air vent (2); the valve core (4) is connected with the valve seat (3) by a spring (6); a sealing ring (7) is arranged on an arc contact surface of the valve core (4) and the plug bush (1); the periphery of the plug bush (1) is provided with a clamping sleeve (9); and a spring (10) is arranged between the clamping sleeve (9) and the plugbush (1). The male connector comprises a plug shaft (12) body, and the plug shaft (12) is internally provided with a valve seat and a valve core in the same structures as in the female connector. Byadopting the structure, the invention ensures that the plug shaft is locked in the hole of the plug bush without falling so as to realize rapid connection. Meanwhile, the axial contact surface of thevalve core and the plug shaft is axially sealed to prevent internal liquid from leaking outwards, and thus the sealing effect is reliable.
Description
Technical field
The present invention relates to a kind of pipe joint structure, especially relate to a kind of double-sealed rapid joint.
Background technique
At present, in electronics, chemical product, oil, water, steam and some gas piping system, self sealing rapid pipe joint is through being commonly used to realize the quick disconnection or the connection of pipeline, and wherein the most commonly used is the negative and positive rapid pipe joints.Negative and positive rapid pipe joint is made of negative joint and male connector, by the spool that pushes part and another joint of a joint and the purpose that is used for reaching the joint break-make between the valve seat, promptly be to open the spool of another joint pipeline is connected, lose and reply by spring after the power of pushing and prevent that medium leaks in the pipeline with the part that pushes of a joint.Push part during negative and positive rapid pipe joint butt joint valve core spring is compressed and conducting, spring ejects spool and seals leaking of medium during disengagement.The self sealing rapid pipe joint of existing structure when male connector inserts and throws off, causes the phenomenon that flowing medium leaks, air is sneaked into sometimes, has influenced the sealing effect of rapid pipe joint.
Summary of the invention
The purpose of this invention is to provide the reliable double-sealed rapid joint of a kind of sealing effect.
The problem that will solve required for the present invention realizes by the following technical solutions: it comprises negative joint and male connector, described negative joint comprises a sleeve body, be provided with the valve seat and the spool of band vent in the sleeve, the sleeve inwall is provided with the spacing jump ring of valve seat, connect with spring between valve seat and the spool, the arc contact surface of spool and sleeve is provided with seal ring, sleeve one end circumferential surface is provided with some holes, establish steel ball in the hole, the sleeve periphery is provided with cutting ferrule, be provided with spring between cutting ferrule and the sleeve, and spacing with the jump ring that is located at sleeve one end; Described male connector comprises that is inserted an axle body, inserts the valve seat and the spool that are provided with the band vent in the axle, inserts an axle inwall and is provided with the spacing jump ring of valve seat, connects with spring between valve seat and the spool, and spool is provided with seal ring with an arc contact surface of inserting spool; Negative joint is provided with seal ring with the installation place that cooperates of male connector.
Establish oblique vent on the spool of the present invention.
The axle of spool of the present invention is installed on the valve seat.
The said structure that the present invention adopts when jointing, produces self-locking action, makes slotting axle be locked in unlikely coming off in the sleeve hole, thereby realizes connecting fast; Spool is realized axial seal with the arc contact surface of inserting axle simultaneously, and internal flow is unlikely to external leakage, and sealing effect is reliable.
Description of drawings
The present invention is described further below in conjunction with accompanying drawing:
Figure 1 shows that the structural representation of the embodiment of the invention 1 negative joint
Figure 2 shows that the structural representation of the embodiment of the invention 1 male connector
Figure 3 shows that the structural representation of the embodiment of the invention 2 negative joints
Figure 4 shows that the structural representation of the embodiment of the invention 2 male connectors
Embodiment
By accompanying drawing as can be known, this double-sealed rapid joint comprises negative joint and male connector, described negative joint comprises sleeve 1 body, be provided with the valve seat 3 and the spool 4 of band vent 2 in the sleeve 1, sleeve 1 inwall is provided with the spacing jump ring of valve seat 5, connect with spring 6 between valve seat 3 and the spool 4, spool 4 is provided with seal ring 7 with the arc contact surface of sleeve 1, sleeve 1 one end circumferential surfacies are provided with some holes 8, establish steel ball in the hole, sleeve 1 periphery is provided with cutting ferrule 9, is provided with spring 10 between cutting ferrule 9 and the sleeve 1, and spacing with the jump ring 11 that is located at sleeve 1 one ends; Described male connector comprises that is inserted axle 12 bodies, insert same valve seat and spool in axle 12 interior employings and the sleeve 1,, insert an inwall and be provided with the spacing jump ring of valve seat promptly with the valve seat and the spool of vent, connect with spring between valve seat and the spool, spool is provided with seal ring with the arc contact surface of inserting axle; Negative joint is provided with seal ring 13 with the installation place that cooperates of male connector, and seal ring 13 can adopt " 0 " RunddichtringO, can guarantee sealing effect when male connector inserts and throws off.For embodiment 1, the rapid pipe joint model is XWD-SV-VIII, can establish oblique vent 14 on the described spool, and fluid passes through from the oblique vent of spool; For embodiment 2, the rapid pipe joint model is XWD-TV-VIII, and the axle 15 of described spool can be installed on the valve seat, and fluid passes through from the poppet shaft external space.
The material of rapid pipe joint of the present invention can adopt carbon steel A, copper B, stainless steel S304,304L, 316L to make, and heatproof degree scope reaches-60～+ 300 ℃, pressure 0.6～30MPa, and structure adopts in inserting axle, sleeve endoporus and respectively puts valve seat and spool.When jointing, draw back the cutting ferrule of sleeve periphery left, make that the steel ball in the hole can freely move radially on the sleeve one end circumferential surface, male connector is being inserted negative joint effectively, being fastened under the spring force effect of sleeve periphery replied, produce self-locking action, make slotting axle be locked in unlikely coming off in the sleeve hole, thereby realize connecting fast.Spool is provided with seal ring with the arc contact surface of inserting axle and realizes axial seal simultaneously, and internal flow is unlikely to external leakage.When need were thrown off the two ends of joint, spool with fast automatic sealing, made the joint internal flow unlikely to external leakage under spring action, thereby realized breaking away from fast and keep internal flow not to the purpose of external leakage.
