Description

Technical Field

[0001] The utility model belongs to the technical field of manifolds, and in particular relates to a valve assembly of a manifold. Background Art

[0002] In the design and application of manifolds, valve assemblies must not only stably and reliably control the on-off flow of water, but also be able to adjust the degree of valve opening and closing to meet flow requirements under different operating conditions. While traditional valve assemblies can perform basic opening and closing operations, they often have limitations in adjusting the degree of valve opening and closing, and cannot provide precise flow control. In application scenarios, precise control of water flow is required, which requires valve assemblies to be able to adjust the degree of valve opening and closing. Traditional valve assemblies often lack this precise adjustment mechanism, resulting in inaccurate flow control, affecting system performance and efficiency. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-11The utility model provides the following technical solutions: a valve assembly of a manifold, comprising a water diversion branch 1, a handle 2, a ball 3, and a ball valve stem 4. A valve seat 5 is provided on the water diversion branch 1, and a limiting mechanism is provided between the handle 2 and the branch, and the limiting mechanism is used to limit the rotation angle of the handle 2.

[0023] In this embodiment, the limiting mechanism includes a ring 6, a sleeve 7, a spring 8, and a push rod 9. The ring 6 is connected to the valve seat 5. The ring 6 is evenly distributed with holding grooves 10 adapted to the push rod 9. The handle 2 is provided with a fitting groove 11 adapted to the sleeve 7. The sleeve 7 is provided with an ejection groove 12 adapted to the push rod 9. The outer wall of the push rod 9 is provided with a supporting ring 13. The spring 8 is sleeved on the outer wall of the push rod 9. The two ends of the spring 8 are respectively in contact with the supporting ring 13 and the bottom wall of the fitting groove 11. The spring 8, the push rod 9, and the sleeve 7 are placed in the fitting groove 11 in sequence.

[0024] With the above structure, the elastic force of the spring 8 enables the push rod 9 to cooperate with the sleeve 7 and the collar 6, and the user can accurately control the rotation angle of the handle 2; secondly, it can ensure that the valve is opened or closed in place;

[0025] For example, if there are 24 clamping grooves 10 evenly distributed on the collar 6, and the angle between two clamping grooves 10 is 15 degrees, when the user rotates the handle 2, each time the end of the push rod 9 is engaged in a clamping groove 10, it means that the handle 2 has been rotated 15 degrees. The above example is not a set number, and the number of clamping grooves 10 can be changed according to actual needs.

[0026] In this embodiment, a clamping ring 14 is provided on the inner wall of the collar 6 , and a clamping groove 15 adapted to the clamping ring 14 is provided on the valve seat 5 .

[0027] With the above structure, the cooperation between the clamping ring 14 and the clamping groove 15 enables the collar 6 to be installed on the valve seat 5 conveniently and quickly, thereby improving the installation efficiency; the close cooperation between the clamping ring 14 and the clamping groove 15 ensures a firm connection between the collar 6 and the valve seat 5, thereby preventing the limit failure caused by looseness.

[0028] In this embodiment, a knurled pin 16 is provided on the outer wall of the sleeve 7 .

[0029] With the above structure, when the handle 2 is removed, the limiting mechanism will not fall out of the handle 2.

[0030] In this embodiment, the handle 2 is provided with a matching groove 17 adapted to the collar 6 .

[0031] With the above structure, the design of the anastomotic groove 17 not only ensures the accurate positioning of the collar 6, but also achieves a hidden structural effect, making the appearance of the valve assembly more concise and beautiful.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
