Description

Technical Field

[0001] This utility model relates to the field of control valves, specifically a water supply and drainage fluid control valve. Background Technology

[0002] Water supply and drainage control valves are important functional components in water supply and drainage systems, used to control or regulate the opening and closing of water supply and drainage channels and the flow rate. They generally consist of a valve body, a valve core, and a handwheel structure that controls the opening and closing of the valve core. When in use, turning the handwheel opens and closes the valve core.

[0003] The handwheel of the control valve is relatively large, and it occupies a lot of installation space as it is exposed outside the valve body. In actual use, the handwheel is just a structural component that makes it easy to grip and apply force. It does not need to be designed to be very large. Moreover, the large handwheel structure is not convenient for installing the control valve in a small space. In addition, the handwheel is exposed outside the valve body and is easily deformed by external impacts and is also susceptible to wind and rain erosion. Utility Model Content

[0004] The purpose of this utility model is to provide a water supply and drainage fluid control valve to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a water supply and drainage fluid control valve, comprising a valve body, wherein a connecting shaft is provided at the top of the valve body, and the connecting shaft is fixedly installed at one end of the valve core inside the valve body, the end of the connecting shaft away from the valve core extends to the outside of the valve body, and an adjustment component is fixedly connected to the top of the connecting shaft.

[0006] Preferably, the adjustment assembly includes a fixed plate fixedly connected to the top of the connecting shaft, and several adjustment slots are respectively opened on both sides of the fixed plate.

[0007] Preferably, each of the adjusting transverse grooves has a sliding plate slidably disposed inside it, and each sliding plate has a connecting crossbar fixedly connected to the end away from the fixed plate.

[0008] Preferably, several connecting crossbars located on the same side are fixedly connected to one end of the handle at the end furthest from the fixed plate.

[0009] Preferably, the fixing plate has mounting grooves on both sides that are adapted to the shape of the handle, and each handle is fixedly connected to one side of the inner wall of the mounting groove by a number of bolts.

[0010] Preferably, each of the adjusting transverse grooves has a limiting sleeve fixedly connected to its inner wall, and the limiting sleeve has a through groove at its center that slides and adapts to the outer side of the connecting crossbar. Each of the mounting vertical grooves is connected to the adjusting transverse groove on the same side.

[0011] Compared with the prior art, the advantages of this utility model are as follows:

[0012] This invention fixes each handle to the side wall of the mounting groove with bolts. When adjustment is needed, each bolt is removed, and each handle is pulled out to one side. The connecting shaft and the valve core at the bottom of the connecting shaft are adjusted using the handles on both sides of the fixing plate. The limiting sleeve is used to limit the slide plate and prevent it from slipping out of the adjustment groove. After adjustment, each handle is snapped into the corresponding mounting groove and fixed with bolts, thus saving space. The handles are also retracted for protection to prevent damage from collisions. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1

[0018] Please see Figures 1-2 The figure shows a water supply and drainage fluid control valve, including a valve body 1. A connecting shaft 2 is provided at the top of the valve body 1, and the connecting shaft 2 is fixedly installed at one end of the valve core inside the valve body 1. The end of the connecting shaft 2 away from the valve core extends to the outside of the valve body 1, and an adjusting component 3 is fixedly connected to the top of the connecting shaft 2.

[0019] In this embodiment, the adjustment assembly 3 includes a fixed plate 31 fixedly connected to the top of the connecting shaft 2. Several adjustment transverse grooves 32 are opened on both sides of the fixed plate 31. A sliding plate 33 is slidably arranged inside each adjustment transverse groove 32. A connecting crossbar 34 is fixedly connected to the end of each sliding plate 33 away from the fixed plate 31. Several connecting crossbars 34 on the same side are fixedly connected to one end of the handle 35 at the end away from the fixed plate 31. The fixed plate 31 has mounting vertical grooves 36 on both sides that are adapted to the shape of the handle 35. Each handle 35 is fixedly connected to one side of the inner wall of the mounting vertical groove 36 by several bolts. A limiting sleeve 37 is fixedly connected to the inner wall of each adjustment transverse groove 32. A through groove adapted to the outer side of the connecting crossbar 34 is opened at the center of the limiting sleeve 37. Each mounting vertical groove 36 communicates with the adjustment transverse groove 32 on the same side.

[0020] Furthermore, each handle 35 is fixedly installed to the side wall of the mounting groove 36 with bolts. When adjustment is required, each bolt of the handle 35 is removed, and each handle 35 is pulled out to one side. The connecting shaft 2 and the valve core at the bottom of the connecting shaft 2 are adjusted through the handles 35 on both sides of the fixing plate 31. The limiting sleeve 37 is used to limit the slide plate 33 to prevent the slide plate 33 from slipping out of the adjusting groove 32. After adjustment, each handle 35 is snapped into the corresponding mounting groove 36 and fixed with bolts, thereby saving space. The handles 35 are also retracted for protection to prevent them from being damaged by collisions.

[0021] The working principle of this utility model is as follows: Each handle 35 is fixedly installed to the side wall of the mounting vertical groove 36 by bolts. When adjustment is required, each bolt of the handle 35 is removed, and then each handle 35 is pulled out to one side. The connecting shaft 2 and the valve core at the bottom of the connecting shaft 2 are adjusted through the handles 35 on both sides of the fixing plate 31. The limiting sleeve 37 is set to limit the slide plate 33 to prevent the slide plate 33 from slipping out of the adjusting horizontal groove 32. After the adjustment is completed, each handle 35 is snapped into the corresponding mounting vertical groove 36 and fixedly installed by bolts, thereby saving space. The handles 35 are also retracted for protection to prevent them from being damaged by collisions.
