DETAILED DESCRIPTION
[0020] The technical scheme of the utility model will be described clearly and completely in combination with the drawings, obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.
[0021] A surgical waste liquid flush suction pipe throttle control structure, comprising a valve body 1, a pressure relief suction assembly 2, a flush assembly 3.
[0022] In one embodiment, as shown in Figures 1 to 4 The pressure relief suction assembly 2 and the flushing assembly 3 are installed on the valve body 1 and connected between the front and rear flushing suction pipes.
[0023] The flushing assembly 3 is composed of a flushing valve core 31 and a flushing channel 32.
[0024] The pressure relief suction assembly 2 is composed of a suction valve core 21, a suction channel 22 and a pressure relief port 23.
[0025] In one embodiment, as shown in Figures 1 to 4 The flushing channel 32 in the flushing assembly 3 is formed inside the valve body 1 from one end to the other end, the flushing valve core 31 is installed on the valve body 1 and the bottom is located in the flushing channel 32, the bottom of the flushing valve core 31 is provided with a valve core port 33, and the rotation of the flushing valve core 31 drives the rotation of the valve core port 33 to control the flow in the flushing channel 32.
[0026] In one embodiment, as shown in Figures 1 to 4 The suction channel 22 in the pressure relief suction assembly 2 is formed inside the valve body 1 from one end to the other end, the pressure relief port 23 is formed on one side of the valve body 1 and is communicated with the suction channel 22 through a pressure relief channel 24, the suction valve core 21 is installed on the valve body 1 and the bottom is located in the pressure relief channel 24, the bottom of the suction valve core 21 is provided with a pressure relief hole 25, and the rotation of the suction valve core 21 drives the rotation of the pressure relief hole 25 to control the pressure in the suction channel 22.
[0027] In one embodiment, as shown in Figures 1 to 4 Both ends of the flushing channel 32 and the suction channel 22 are provided with a catheter interface 4.
[0028] In one embodiment, as shown in Figures 1 to 4 The valve body 1 is provided with a flow identifier 5.
[0029] In one embodiment, as shown in Figures 1 to 4 A rubber sealing ring 6 is arranged between the flushing valve core 31 and the flushing channel 32 and between the suction valve core 21 and the pressure relief channel 24.
[0030] The pressure relief suction assembly 2 and the flushing assembly 3 are installed on the valve body 1 and connected between the front and rear flushing suction pipes through the catheter interface 4; the specific working principle comprises the following:
[0031] The working principle of the flushing assembly 3: when the flushing valve core 31 (flushing switch) rotates, liquid can be conducted when the valve core port 33 is communicated with the flushing channel 32, and is blocked when the valve core port 33 and the flushing channel 32 are not communicated.
[0032] The working principle of the pressure relief suction assembly 2 is that there is a pressure relief port 23 on the valve body 1, which is connected with the suction channel 22 through a pressure relief channel 24. When the suction valve core 21 (suction switch) rotates, the pressure relief hole 25 is communicated with the pressure relief port 23 on the valve body 1. When a large amount of air is sucked in, the pressure inside the suction channel 22 is reduced, thereby reducing the flow of the suction liquid. When the suction valve core 21 rotates to the position where the pressure relief hole 25 is not communicated with the pressure relief port 23, air cannot be sucked in, thereby ensuring that the pressure inside the suction channel 22 does not change and the flow does not change. The change of the pressure is realized by adjusting the communication area of the pressure relief hole 25 and the pressure relief port 23. The larger the communication area, the greater the change of the pressure inside the suction channel 22, and the more the flow decreases. The communication area is adjusted by rotating the suction valve core 21 (suction switch).
[0033] Obviously, the above embodiments are only examples for clearly illustrating, but not limitation to the embodiments. Based on the above description, other different forms of changes or variations can be made by those skilled in the art. Here, it is not necessary and impossible to enumerate all the embodiments. The obvious changes or variations derived therefrom are still within the protection scope of the present application.
