Description

Technical Field

[0001] The utility model relates to the technical field of valves, and particularly relates to an adjustable rotary directional valve. Background Art

[0002] Valves are mainly applied to industries such as HVAC, water supply, bathroom systems and other industrial or civil industries that require fluid transportation and control, and play a role in connecting and locking between valves and pipelines or interfaces.

[0003] The existing valves are basically connected to pipelines by welding or threaded connection. Welding connection is non-detachable and not convenient for maintenance. Threaded connection is prone to nut loosening, resulting in poor sealing reliability. The connection between the existing valves and pipelines is mostly a single-sealing structure, with poor sealing performance and easy leakage. At the same time, after the existing valves are installed by threaded connection, the angle cannot be adjusted, which is not conducive to opening or closing the valves later. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable rotary directional valve.

[0005] An adjustable rotary directional valve includes a connecting square pipe and a valve body. The connecting square pipe and the valve body can be rotated and adjusted by 90° through a connecting device, and a locking device and a sealing device are arranged between the connecting device and the valve body.

[0006] Further, the connecting device includes a connecting head and a connecting nut. The connecting head is fixedly arranged on the outer side of the connecting square pipe. A cross-shaped water outlet groove is opened on the side wall of the connecting square pipe located in the inner cavity of the connecting head. Two plugs detachably matched with the cross-shaped water outlet groove are fixedly arranged at the water inlet end of the valve body. A connecting nut is sleeved outside the water inlet end of the valve body and the connecting head, and the connecting nut is in threaded fit with the connecting head.

[0007] Further, the sealing device includes a sealing ring and a conical sealing gasket. A sealing ring groove is arranged outside the water inlet end of the valve body close to the cross-shaped water outlet groove. A sealing ring matched with the inner wall of the connecting head is arranged in the sealing ring groove. A conical sealing gasket matched with the inner wall of the connecting head is sleeved outside the water inlet end of the valve body behind the sealing ring.

[0008] Further, the locking device includes a locking wire. A locking ring groove is arranged outside the water inlet end of the valve body behind the connecting head. A locking wire matched with the connecting nut is arranged in the locking ring groove. A wire insertion hole matched with the locking ring groove is opened on the outer wall of the connecting nut.

[0009] In summary, the utility model has the following beneficial effects:

[0010] The connecting square pipe and the valve body of the present utility model are connected through a connecting device. Through the connecting device, the valve body can be rotated and adjusted by 90° according to requirements, which is convenient for the opening and closing operation of the valve body. A sealing device is arranged between the connecting device and the valve body to achieve double sealing and improve the sealing performance of the connection between the connecting square pipe and the valve body. The locking device locks the connecting device to prevent the connecting device from loosening during use and improve the reliability of the seal. Description of the Drawings

Specific Embodiments

[0017] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] The following will further illustrate the present utility model in conjunction with the attached Figures 1-4 The present utility model is further described as follows:

[0019] An adjustable rotary orientation valve includes a connecting square pipe 1 and a valve body 2. The connecting square pipe 1 and the valve body 2 can be rotated and adjusted by 90° through a connecting device 3. A locking device 4 and a sealing device 5 are arranged between the connecting device 3 and the valve body 2.

[0020] In this embodiment, the connecting square pipe 1 and the valve body 2 are connected through a connecting device 3. Through the connecting device 3, the valve body 2 can be rotated and adjusted by 90° according to requirements for installation, which facilitates the opening and closing operation of the valve body 2. A sealing device 5 is arranged between the connecting device 3 and the valve body 2 to achieve double sealing and improve the sealing performance of the connection between the connecting square pipe 1 and the valve body 2. The locking device 4 locks the connecting device 3 to prevent the connecting device 3 from loosening during use and improve the reliability of the sealing.

[0021] The connecting device 3 includes a connecting head 31 and a connecting nut 32. The connecting head 31 is fixedly arranged on the outer side of the connecting square pipe 1. A cross-shaped water outlet groove 33 is formed on the side wall of the connecting square pipe 1 located in the inner cavity of the connecting head 31. Two insertion blocks 34 detachably matched with the cross-shaped water outlet groove 33 are fixedly arranged at the water inlet end of the valve body 2. A connecting nut 32 is sleeved outside the water inlet end of the valve body 2 and the connecting head 31, and the connecting nut 32 is in threaded fit connection with the connecting head 31.

[0022] In this embodiment, the water inlet end of the valve body 2 is inserted into the connecting head 31. The insertion of the two insertion blocks 34 at the water inlet end of the valve body 2 into the cross-shaped water outlet groove 33 can achieve a 90° rotation to adjust the angle of the valve body 2, which facilitates the opening and closing operation of the valve body 2. The connecting nut 32 is used to realize the connection between the connecting head 31 and the water inlet end of the valve body 2.

[0023] The sealing device 5 includes a sealing ring 52 and a conical sealing gasket 53. A sealing ring groove 51 is arranged outside the water inlet end of the valve body 2 near the cross-shaped water outlet groove 33. A sealing ring 52 matched with the inner wall of the connecting head 31 is arranged in the sealing ring groove 51. A conical sealing gasket 53 matched with the inner wall of the connecting head 31 is sleeved outside the water inlet end of the valve body 2 behind the sealing ring 52.

[0024] In this embodiment, a sealing ring 52 and a conical sealing gasket 53 are sequentially arranged between the outer part of the water inlet end of the valve body 2 and the inner wall of the connecting head 31 to achieve double sealing and improve the sealing performance of the connection between the connecting square pipe 1 and the valve body 2.

[0025] The locking device 4 includes a locking wire 42. A locking ring groove 41 is arranged outside the water inlet end of the valve body 2 behind the connecting head 31. A locking wire 42 matched with the connecting nut 32 is arranged in the locking ring groove 41. A wire insertion hole 43 matched with the locking ring groove 41 is formed on the outer wall of the connecting nut 32.

[0026] In this embodiment, the locking wire 42 is a wire of a fixed length before use. After the connecting nut 32 fastens the connection between the connecting head 31 and the water inlet end of the valve body 2, one end of the locking wire 42 is inserted into the locking ring groove 41 through the wire insertion hole 43. Then, with the aid of a tool, an external force is used to insert the whole locking wire 42 into the locking ring groove 41 through the wire insertion hole 43 and form a ring-shaped locking wire 42. The ring-shaped locking wire 42 is snapped into the locking ring groove 41, and a part of the locking wire 42 protrudes from the locking ring groove 41 to restrict the rotation of the connecting nut 32 and prevent the connecting nut 32 from loosening, ensuring the reliability of the seal.
