Abstract
The utility model discloses a double-seal quick coupling comprising a female coupling and a male coupling. The female coupling comprises a plug bush (1) body; the plug bush (1) is internally provided with a valve seat (3) with ventilation holes (2) and a valve core (4); a spring (6) is coupled between the valve seat (3) and the valve core (4); the arc contact face of the valve core (4) and the plug bush (1) is provided with a seal ring (7); the periphery of the plug bush (1) is provided with a cutting sleeve (9); a spring (10) is installed between the cutting sleeve (9) and the plug bush (1); the male coupling comprises a plug shaft (12) body; and the plug shaft (12) is internally provided with a valve seat and a valve core having the same structure. The structure above is used so that the plug shaft is blocked in the plug bush without being fallen off, thereby realizing quick connection; simultaneously, the arc contact face of the valve core and the plug shaft realizes axial sealing and the internal fluid cannot leak outwards, thereby having reliable sealing effect.
Description
Technical field
The utility model relates to a kind of pipe joint structure, especially relates 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 utility model provides the reliable double-sealed rapid joint of a kind of sealing effect.
The problem of the required solution of the utility model 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 described in the utility model.
The axle of spool described in the utility model is installed on the valve seat.
The said structure that the utility model 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
Below in conjunction with accompanying drawing the utility model is described further:
Figure 1 shows that the structural representation of the utility model embodiment 1 negative joint
Figure 2 shows that the structural representation of the utility model embodiment 1 male connector
Figure 3 shows that the structural representation of the utility model embodiment 2 negative joints
Figure 4 shows that the structural representation of the utility model embodiment 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 " O " 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 the utility model rapid pipe joint 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.
