[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example:

[0025] See also Figure 1-Figure 2 The utility model provides a valve volume control device, including a valve body 1, a pipe connection port 2 is installed at the lower position of the valve body 1, a stainless steel lining frame 3 is fixedly installed at the inner cavity position of the valve body 1, a rubber sealing surface 4 is provided on the inner wall of the stainless steel lining frame 3, a through hole connected to the pipe connection port 2 is provided on the stainless steel lining frame 3 and the rubber sealing surface 4, a screw rod 5 is movably installed at the bottom of the valve body 1, a shut-off body 6 is threadedly installed on the screw rod 5, an outer wall of the shut-off body 6 is in sealing contact with the rubber sealing surface 4, and an arc groove 7 is provided on the side of the shut-off body 6 facing the pipe connection port 2.

[0026] Specifically, Figure 1 As shown, the valve body 1 and the shut-off body 6 are rectangular in shape, and the sealing contact surface is large.

[0027] Specifically, Figure 1 As shown, the heights of the stainless steel liner frame 3 and the rubber sealing surface 4 are the same, and the height of the shut-off body 6 is smaller than that of the stainless steel liner frame 3 and the rubber sealing surface 4, thereby saving materials.

[0028] Specifically, Figure 1 As shown, the bottom of the surface of the shut-off body 6 facing the pipe port 2 is cut obliquely to form a guiding inclined surface, and the arc groove 7 is arranged above the guiding inclined surface to facilitate the smooth descent of the shut-off body 6.

[0029] Working principle:

[0030] When in use, by operating the screw rod 5, the higher the height to which the shut-off body 6 is lifted, the greater the amount of fluid flowing through the valve body 1; the lower the height to which the shut-off body 6 is lowered, the smaller the amount of fluid flowing through the valve body 1; after the shut-off body 6 touches the bottom, the fluid is cut off; since the arc groove 7 is provided on the shut-off body 6, it can buffer the impact of the fluid and reduce noise and speed; and the rubber sealing surface 4 is in contact with the shut-off body 6, the sealing effect is high and the noise in use is small.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
