The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

Referring to fig. 1-3, the present invention provides an embodiment: a check valve convenient for plugging and unplugging a pipeline comprises a valve body 1, wherein one end of the valve body 1 is provided with a first connecting part 5, and the other end of the valve body 1 is provided with a second connecting part 11; a cavity 2 is further arranged inside the valve body 1, and a valve clack 4 is arranged in the cavity 2; one surface of the valve flap 4, which is far away from the second connecting part 11, is connected with the bottom surface of the cavity 2 through a spring 3; the second connecting part 11 comprises a pressing cap 10, a tightening sleeve 9, a clamp spring 8, a sealing ring 7 and a clamping seat 6; the pressing cap 10 is connected with the valve body 1, so that the tightening sleeve 9, the clamp spring 8, the sealing ring 7 and the clamping seat 6 are sequentially assembled into the valve body 1 from top to bottom, and the first connecting portion 5 is consistent with the second connecting portion 11 in structure.

In conclusion, due to the arrangement of the first connecting part 5 and the second connecting part 11, the air pipe can be quickly inserted and pulled out by the device through the connecting mechanism of the quick connector; meanwhile, the valve clack 4 is utilized to enable the device to realize the one-way conduction function of an air source; meanwhile, the air pipe can be conveniently pulled out of the valve body 1 by pressing the pressing cap 10; and then make tracheal plug simple and convenient, especially, valve clack 4 and spring 3's setting can realize the inside one-way conduction of valve body 1, so can control the flow direction of air supply, avoids the air supply backward flow.

In addition, the tight-lock sleeve 9 is made of stainless steel to solve the problem that the zinc alloy is easy to oxidize and rot when meeting water. Meanwhile, the outer diameter of the valve body 1 is 11.6mm, so that the volume of the valve body 1 of the equipment is reduced.

On the basis of the above scheme, the valve flap 4 includes a support portion 41, and the support portion 41 is abutted against the lower bottom surface of the clamping seat 6 through a protrusion 40. When the air supply moves from first connecting portion 5 to second connecting portion 11 direction, utilize arch 40 and supporting part 41 to contradict, realize cutting off of air supply, the setting of spring 3 simultaneously also can guarantee under the condition that does not have the air supply that arch 40 and cassette 6 are contradictory to improve equipment's sealing capacity.

Further, the protrusion 40 is movably mounted on the support portion 41, and the protrusion 40 is made of rubber, so that the deformation of the protrusion is utilized to enhance the sealing performance between the valve flap 4 and the clamping seat 6.

In order to ensure that the valve flap 4 slides smoothly in the cavity 2 and prevent the valve flap 4 from blocking the flow of an air source, the supporting part 41 is further provided with a plurality of guide parts 42 with consistent structures; wherein the outer diameter of the guide parts 42 is equal to the inner diameter of the cavity 2, and an air flow channel 44 is formed between any two adjacent guide parts 42. The outer diameter of the guide part 42 is equal to the inner diameter of the cavity 2, so that the valve clack 4 can slide along the inner wall of the cavity 2, and the problem of sealing failure caused by the deviation of the valve clack 4 on the axis is avoided; while the air flow passage 44 is provided so that the valve flap 4 does not obstruct the air flow to the first connection portion 5 when sliding.

Furthermore, because the positioning part 43 is further arranged below the supporting part 41, the positioning part 43 is sleeved in the spring 3, and the diameter of the guide part 42 is larger than the outer diameter of the spring 3, one end of the spring 3 can be stably connected with the valve clack 4 in the above manner, and the problem that the sealing capacity of the device is reduced due to the separation of the spring 3 and the valve clack 4 is avoided.

In addition, the device can be applied to the unidirectional conduction of the liquid medium when the air source is in unidirectional conduction.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
