Referring to fig. 1 to 7, a valve includes: the valve comprises a valve body 10 and an air inlet end 20, wherein the air inlet end 20 is arranged at one end of the valve body 10, the air inlet end 20 is used for being connected with an air inlet pipeline 70 so as to be communicated with an air source, at least two clamping devices are further arranged on the valve body 10, the clamping devices are positioned on the outer side of the air inlet end 20, and the clamping devices are used for clamping a pipe orifice of the air inlet pipeline 70 so as to fixedly connect the air inlet pipeline 70 with the air inlet end 20; and the air outlet end is positioned on the valve body 10 and is used for exhausting air. The at least two detent means are preferably evenly arranged along the circumference outside the air inlet end 20, preferably two detent means. Therefore, when the clamping device clamps the air inlet pipeline 70, the stress of the air inlet pipeline 70 is more uniform, and the hidden danger of air leakage is reduced.

The detent device preferably comprises: the middle part of the buckle 30 is provided with a rotating shaft 31 pivoted with the valve body 10, and the buckle 30 can swing around the rotating shaft 31 relative to the valve body 10; one end of the buckle 30 is provided with a hook 32, the hook 32 is used for being matched with a clamping groove on the air inlet pipeline 70, the hook 32 is connected with an elastic device for driving the hook 32 to swing towards the clamping groove, the other end of the buckle 30 is provided with a pressing part 33, and the pressing part 33 is used for driving the hook 32 to be separated from the clamping groove. The pressing portion 33 may be directly pressed by a human hand or may be driven by a third member, such as the driving lever 35 in fig. 3 and 4. When the pipe orifice of the air intake pipe 70 enters the air intake end 20, the hook 32 is pushed away under the action of the guide surface 41 of the pipe orifice of the air intake pipe 70, then the hook 32 presses the surface of the air intake pipe 70, the elastic device gives a force to the hook 32 always facing the surface of the air intake pipe 70, when the air intake pipe 70 is inserted into the air intake end 20 until the hook 32 corresponds to the clamping groove on the air intake pipe 70, the hook 32 is clamped into the clamping groove under the action of the elastic device, so that the hook 32 clamps the air intake pipe 70, the air intake pipe 70 cannot be separated from the air intake end 20, when the restriction of the air intake pipe 70 and the air intake end 20 needs to be released, the pressing part 33 is pressed down, and the hook 32 swings under the action of the rotating shaft 31, so that the hook 32 is separated from the clamping groove, and the air intake pipe 70 can move freely relative to the air intake end 20. The resilient means is preferably a resilient spring 34, less preferably a spring.

The detent device less preferably comprises: the guide block 40 is positioned in the valve body 10, and a guide surface 41 is also arranged on the guide block 40; the clamping block 50 is positioned on the guide block 40, the clamping block 50 can move along the guide surface 41, one end of the clamping block 50 is also provided with a hook head 52, and when the clamping block 50 moves along the guide surface 41, the hook head 52 can be matched with a clamping groove on the air inlet pipeline 70 so as to clamp the air inlet pipeline 70; and the driver is connected with the clamping block 50 and is used for driving the clamping block 50 to move along the guide surface 41.

The actuator is preferably a valve rod 60, the valve rod 60 is located in the valve body 10 and can rotate in the valve body 10, the clamping block 50 is provided with a through hole 51, the valve rod 60 penetrates through the through hole 51, and the valve rod 60 can drive the through hole 51 to move when rotating so as to drive the clamping block 50 to move. The valve rod 60 preferably includes a section of eccentric rod 61 on the valve rod 60, and the eccentric rod 61 is located in the through hole 51, when the eccentric rod 61 rotates, the valve rod 60 drives the clamping block 50 to move along the guiding surface 41. The actuator is preferably a dial block which is connected to the detent block 50 and by which the detent block 50 can then be actuated.

For the convenience of the present invention, two detent arrangements are selected, one for each of the preferred and less preferred arrangements, symmetrically disposed along the outside of the air intake end 20. When the valve is installed, the valve is pressed into the air inlet pipe 70, and at this time, the hook 32 in the preferred embodiment will block the air inlet pipe 70, thereby restricting one side of the air inlet pipe 70, and then the valve rod 60 is rotated, so that the block 50 also blocks the air inlet pipe 70, thereby restricting the other side of the air inlet pipe 70. When the valve is removed, the valve rod 60 is rotated to release the restriction of the stopper 50 on the air intake duct 70, the pressing portion 33 is pressed to release the restriction of the hook 32 on the air intake duct 70, and the valve is pulled out. The preferred embodiment has a better restriction effect on the air intake duct 70, but in order to achieve a good effect, a larger force is generally required to restrict the air intake duct, a larger force is required in the process of pressing the pressing portion 33, the less preferred embodiment is very labor-saving in use, but is quite high in flexibility and easy to fall off, and the preferred embodiment and the less preferred embodiment are respectively selected to be arranged on the outer side of the air intake end 20, so that the respective advantages of the preferred embodiment and the less preferred embodiment can be combined, the invention does not need to be too labor-saving, can have a good restriction effect, and effectively reduces the hidden trouble of air leakage caused by the fact that the air intake duct 70 is easily inclined due to the unilateral stress caused by the unilateral buckling of the air intake duct 70 compared with the prior art.

Preferably, the valve rod 60 is further provided with a sealing part 62, and the sealing part 62 is used for sealing the air inlet end 20 or opening the air inlet end 20, so that the valve rod 60 cannot drive the clamping block 50 to move when rotating, the valve rod 60 drives the clamping block 50 to limit the air inlet pipeline 70, the valve rod can further play a role in sealing or opening the air inlet end 20, the number of parts of the valve can be reduced, and the operation is simpler.
