After the pressing portion 6 is pressed down, the lower end surface of the sealing ring 9 is separated from the bottom end surface of the groove 8 to form a flow gap 2 11. The flow gap 2 11 ensures that the inlet 2 and the outlet 3 are connected. A spring 12 is sleeved on the outer side of the upper end of the valve body 1, with one end abutting against the outer wall of the valve body 1 and the other end abutting against the bottom of the pressing portion 6.

[0025] Preferably, in order to improve the sealing performance, a second groove 13 is provided above the pressing rod 7, and a second sealing ring 14 is provided in the second groove 13, whose outer wall abuts against the inner wall of the pressing hole 4, so that the sealing effect is improved by providing the second sealing ring 14.

[0026] Preferably, in order to facilitate internal cleaning and limit the sealing ring, an opening 15 is provided at the bottom of the valve body 1, and a bottom cover 16 is covered on the opening 15. The bottom cover 16 is provided with a pressing ring 17 for pressing the sealing ring 9 into the pressing hole 4. In this structure, the pressing ring 17 is provided on the bottom cover 16, and the sealing ring 9 is pressed tightly into the pressing hole 4 by utilizing the pressing ring 17.

[0027] Preferably, in order to improve the sealing performance, a sealing ring 18 is provided on the outer side of the bottom cover 16, and the outer wall of the sealing ring 18 abuts against the inner wall of the pressing hole 4. The sealing ring 18 is provided to improve the sealing effect between the bottom cover 16 and the inside of the valve body 1.

[0028] Preferably, for easy disassembly, buckles 19 are provided on both sides of the bottom cover 16, and slots 20 cooperating with the buckles 19 are provided on both sides of the valve body 1. In this structure, the bottom cover 16 and the valve body 1 are connected by buckles to facilitate later disassembly.

[0029] Preferably, in order to improve the fixing effect, one or more positioning through holes 21 are provided on the bottom cover 16, and one or more screw holes 22 are provided on the outer side of the valve body 1. Each screw hole 22 is aligned with a positioning through hole 21 to further improve the locking effect. Later, screws are passed through the positioning through holes 21 and threadedly connected with the screw holes 22 to achieve the fixing effect of the bottom cover 1. It should be noted that in order to facilitate the installation of this structure, one or more hanging ears 25 are provided on the bottom side of the valve body 1, and mounting through holes 26 are provided on the hanging ears 25.

[0031] The working principle of this structure is described as follows:

[0032] 1. If Figure 4 As shown, in the initial state, the spring 12 pulls the adjustment button 5 upward, and the bottom of the adjustment button 5 and the sealing ring 9 are in a closed state, and the fluid cannot pass through, thus achieving sealing;

[0033] 2. If Figure 5As shown, when in the open state, the regulating button 5 is pressed, and the spring 12 is compressed at this time, and the bottom of the regulating button 5 is separated from the sealing ring 1 9 to form a flow gap 2 11. At this time, the fluid enters from the inlet 2, flows through the flow gap 2 11, and goes out from the outlet 3 after passing through the flow gap 10. When the regulating button 5 is released, the valve is reset and sealed. The more it is pressed, the larger the gap of the flow gap 2 11 is, and the more water is sprayed. Therefore, this structure is applied to the water system to control the injection of the fluid and stop the operation. In addition, the whole structure is simple, with fewer parts, and the installation is relatively convenient. The overall volume is reduced, and it can be used to control high-temperature steam.

[0034] 3. A detachable bottom cover 16 is provided at the bottom of the structure to facilitate cleaning of the pressing hole 4.
