Detailed Description
In order to further illustrate the technical means and technical effects adopted by the present invention, the present invention is described in detail below with reference to specific embodiments.
The button type fluid connector capable of realizing miniaturization comprises a plug connector and a socket connector, as shown in figure 2, the plug connector comprises a plug shell 1, a valve rod I2 and a fixing block I3 which are arranged in the plug shell, a spring I4 arranged between the valve rod I and the fixing block I, a clamp spring I5 arranged on the inner wall of the tail portion of the plug shell and used for supporting the fixing block I and the like. The plug shell provides supporting and protecting functions for the plug, and the outer wall of the plug shell is sealed through the matching surface of the O-shaped sealing ring I6 and the mounting hole. The surface quality of the plug housing has a great influence on the sealing performance and appearance quality of the product. An internal seal is formed between the valve rod I and the plug shell through an O-shaped seal ring II 7, and the size and the surface processing performance of a groove for mounting the O-shaped seal ring II directly influence the sealing function of a product; the front end of the plug shell is also provided with an O-shaped sealing ring III 8 for realizing sealing with a sealing block 17 on the socket connector. The tail of the valve rod I is arranged in a central hole of the fixing block I and can axially slide along the central hole of the fixing block I, the front end of the valve rod I extends out of the front end horizontal plane of the plug shell to form pushing acting force with the valve rod II in the socket when the head seat is plugged, so that the valve rod I is stressed to compress the spring I and axially slide along the central hole of the fixing block I to separate the valve rod I from the plug shell. The spring I is used for providing restoring force and pretightening force for the valve rod I so as to realize tight sealing between the valve rod I and the plug shell; fixed block I plays supporting spring I and the effect of I position of restriction valve rod. The plug housing is constructed such that a first flow passage 9, a second flow passage 10 and a first cavity 11 are formed in the plug housing as shown in fig. 2. The front end of the plug housing is further provided with a recess 12 for connection with a connection portion 27 of the front end of the plug housing by means of a clearance fit.
As shown in fig. 3, the socket connector of the present invention includes a socket housing 13, a valve rod ii 14 and a fixing block ii 15 disposed in the socket housing, a valve core 16 disposed on the periphery of the valve rod ii and capable of sliding along the axial direction of the valve rod ii, a sealing block 17 fixedly connected with the front end of the valve core, a spring ii 18 disposed between the valve core and the fixing block ii and providing restoring force and pre-tightening force for the valve core, and a snap spring ii 19 disposed on the inner wall of the tail portion of the socket housing and used for supporting the fixing block ii. The socket shell provides supporting and protecting functions for the socket and realizes sealing through the matching surface of the O-shaped sealing ring IV 20 and the mounting hole. The surface quality of the socket housing has a great influence on the sealing performance and appearance quality of the product. An internal seal is formed between the valve core and the socket shell through an O-shaped sealing ring V21, and the sealing function of a product is directly influenced by the size and the surface processing performance of a groove for mounting the O-shaped sealing ring V on the valve core; the sealing block 17 is sealed with the connecting portion 27 at the front end of the socket through an O-shaped sealing ring VI 22, the sealing block is matched with the connecting portion 27 of the socket shell to form a movable sealing structure through the O-shaped sealing ring VI, and the flow performance of a product is directly influenced by the processing quality of the inclined plane and the curved surface of the sealing block. And the valve core and the valve rod II are sealed by an O-shaped sealing ring VII 23. Under the action of external force, the sealing block can axially slide along the inner wall of the front end of the socket shell. The sealing block and the valve core can be of an integral structure or can be connected through thread gluing, and the thread gluing refers to that the sealing block and the valve core are connected together through threads after the threads of the sealing block and the valve core are glued. The valve rod II and the fixing block II can be of an integral structure or can be two independent parts which are fixed together. The spring II is used for providing restoring force and pretightening force for the valve core so as to realize sealing between the valve core and the socket shell; and the fixing block II plays a role in supporting the spring II and limiting the position of the valve core. The socket housing is constructed such that a third flow passage 24, a fourth flow passage 25 and a second cavity 26 are formed in the socket housing as shown in fig. 3.
Further, instead of the sealing manner of the O-ring ii 7, the O-ring v 21, the O-ring vi 22, and the O-ring vii 23, a rubber vulcanization manner may be employed. The following scheme can be specifically adopted: the part is placed in a mould, special glue solution is smeared at the groove of the O-shaped sealing ring, then rubber material is placed in the mould, and the rubber material is vulcanized on the part in a vulcanizing machine to form a sealing ring shape. The process mode has the advantages that the sealing element is not easy to fall off (because of the glue solution), and the defects of complex process and high cost.
As shown in fig. 4, when the head base is plugged, when the plug is just contacted with the housing of the socket connector, the valve rod i and the valve rod ii should be just contacted or about to be contacted, and are continuously plugged, because the position of the valve rod ii is fixed, under the action of the plugging force, the valve rod i is stressed to extrude the spring i, the tail of the valve rod i axially slides to the left side shown in fig. 4 along the central hole of the fixed block i, and finally, the valve rod i is separated from the plug housing, so that the fifth flow channel 28 in the plug connector is opened. Meanwhile, as the fixing part 29 in the plug shell is fixed, under the action of the inserting combination force, the fixing part 29 extrudes the sealing block in the socket connector to enable the sealing block to axially slide towards the right side shown in fig. 4 along the inner wall of the connecting part 27 at the front end of the socket shell, as the valve core and the sealing block are integrated or fixedly connected through thread gluing, the valve core is stressed to compress the spring II and axially slide towards the right side shown in fig. 4 along the valve rod II, finally, the valve core and the socket shell are separated through the part sealed by the O-shaped sealing ring V21, a sixth flow passage 30 in the socket connector is opened, and meanwhile, the connecting part 27 at the front end of the socket is inserted into the groove 12 at the front end of. The state diagram that the headstock inserted and closes in place is shown in fig. 5, and in the recess of plug housing front end was inserted to the connecting portion of socket housing front end, valve rod I and II close contact of valve rod, spring I provided the pretightning force for valve rod I, and valve rod I is spacing through fixed block I. And the spring II provides pretightening force for the valve core. The fixing part 29 in the plug and the sealing block 17 in the socket are in close contact, and the fixing part and the sealing block are sealed through an O-shaped sealing ring III. Taking the case that the fluid flows from the plug to the socket, the fluid sequentially passes through the first flow channel, the first cavity, the fifth flow channel and the second flow channel in the plug connector, enters the socket connector, sequentially passes through the third flow channel, the sixth flow channel and the second cavity in the socket connector, and finally flows out of the fourth flow channel.
After the headstock is separated, under the action of the spring I, the position of the valve rod I is restored and is sealed with the plug shell through the O-shaped sealing ring II, and under the action of the spring II, the positions of the valve core and the sealing block are restored and the valve core and the socket shell are sealed through the O-shaped sealing ring V.
