Description

Technical Field

[0001] The present application relates to the field of fluid control, and in particular to a stop valve that is easy to install. Background Art

[0002] In the field of fluid control, the stop valve is a key device for regulating and cutting off the flow of fluid, and its performance directly affects the stability and operating efficiency of the system. However, the ball valve type stop valves currently on the market generally have some shortcomings in the design of the water inlet and outlet sealing devices.

[0003] Traditional ball valves mostly use simple annular seals to achieve water inlet and outlet sealing. Although this design can meet basic sealing requirements to a certain extent, the installation process of the annular seal is relatively complicated and requires precise alignment and appropriate force to ensure the sealing effect, which undoubtedly increases the difficulty and cost of installation.

[0041] The main body 31 of the sealing component 30 is embedded in the valve core 20, which can reduce the difficulty of installing the sealing component 30 and improve the installation efficiency of the sealing component 30, thereby improving the installation efficiency of the stop valve 100; in addition, the sealing lip 32 on the sealing component 30 can improve the sealing performance and avoid water leakage problems of the stop valve 100.

[0042] In this embodiment, if Figures 1 to 4 As shown, the stop valve 100 may be a ball valve. The stop state of the stop valve 100 is: at least one of the inlet 11 and the outlet 12 is sealed, and there is no conduction between the inlet 11 and the outlet 12. The conduction state of the stop valve 100 is: the inlet 11 and the outlet 12 are connected.

[0043] In this embodiment, if Figures 1 to 4 As shown, the structure of the valve body 10 is not strictly limited; for example, the structure of the valve body 10 is generally a cylindrical structure. The valve body 10 has an axial direction in space; one end of the valve body 10 is a closed side, and the other end is an open side; the valve body 10 is an opening on the open side. The valve body 10 has a valve cavity 13; the opening, the inlet 11 and the outlet 12 are all connected to the valve cavity 13. Among them, the inlet 11 and the outlet 12 are arranged on both sides of the valve body 10 in the radial direction.

[0047] In this embodiment, as Figures 1 to 6 shown, the valve core 20 is snap-connected to the valve body 10, which facilitates the disassembly and assembly between the valve core 20 and the valve body 10. The valve core 20 has a tongue 22, and the valve body 10 has a snap-in portion 14. The tongue 22 can be snapped into the snap-in portion 14 so that the valve core 20 is snapped to the valve body 10. The snap-in portion 14 is annularly arranged and adjacent to the opening of the valve body 10 so that when the valve core 20 is rotated, the tongue 22 can slide along the snap-in portion 14. Of course, in other embodiments, the valve core 20 has a snap-in portion 14, and the valve body 10 has a tongue 22. The tongue 22 can be snapped into the snap-in portion 14 so that the valve core 20 is snapped to the valve body 10.

[0048] In this embodiment, as Figures 1 to 6 shown, the valve core 20 has an installation groove 21, and the main body portion 31 is embedded in the main body portion 31; wherein, along the radial direction of the valve core 20, the depth of the installation groove 21 is at least greater than 5 mm so that the sealing member 30 can penetrate into the interior of the valve core 20 to avoid the problem that the sealing member 30 is easily detached. Preferably, along the radial direction of the valve core 20, the depth of the installation groove 21 is at least greater than 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm or 12 mm and above.
