Description

Technical Field

[0001] This utility model relates to the technical field of directional valve equipment, specifically a multi-position directional valve. Background Technology

[0002] A directional control valve is an important component widely used in fluid control systems. It mainly consists of a valve body, a valve core, and an operating mechanism. The operating mechanism drives the valve core to change position within the valve body, thereby controlling the flow direction of fluids, including liquids and gases. This allows the fluid to switch between different pipelines or working ports to meet different operational requirements. It plays a crucial role in many fluid transport and control scenarios in industry, agriculture, construction, and daily life.

[0003] Directional control valves switch fluid between different pipelines by switching the valve core to different positions, thereby controlling the fluid flow direction and starting / stopping actuators. However, existing multi-position directional control valves have a relatively complex structure with nested components, making disassembly and installation cumbersome and requiring specialized tools and technicians. This increases maintenance costs and time, affecting the normal use of the equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-position directional valve to solve the problems of existing multi-position directional valves having a complex structure, nested components, cumbersome disassembly and installation processes, requiring professional tools and technicians, increasing maintenance costs and time, and affecting the normal use of equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-position reversing valve, comprising: a valve body, wherein a valve seat mechanism is provided inside the valve body, a reversing mechanism is provided on the top of the valve body, a through pipe is fixedly connected to the side wall of the valve body, a sealing ring groove is provided at the bottom inside the valve body, and a connecting flange is fixedly connected to the upper outside of the valve body.

[0006] As a further embodiment of this utility model: the valve seat mechanism includes an inner valve seat and a multi-directional flow channel. The inner valve seat is movably inserted into the valve body, and the multi-directional flow channel is opened inside the inner valve seat. There are two sealing gaskets: a first sealing gasket and a second sealing gasket. The first sealing gasket is fixedly connected to one bottom end of the inner valve seat, and the second sealing gasket is fixedly connected to one top end of the inner valve seat. The first sealing ring groove is adapted to the first sealing gasket.

[0007] As a further embodiment of this utility model: the reversing mechanism includes a sealing valve cover, a second sealing ring groove, and a second connecting flange. The second sealing ring groove starts at one bottom end of the sealing valve cover, and the second connecting flange is fixedly connected to the lower outer side of the sealing valve cover. The second sealing ring groove is adapted to the second sealing gasket. The mechanism also includes a steering shaft, a valve core, and a handle. The steering shaft is rotatably connected inside the sealing valve cover, and both ends of the steering shaft extend to the outside of the sealing valve cover. The valve core is rotatably connected to the inner side of the multi-directional flow channel. One end of the steering shaft passes through the inner valve seat and is fixedly connected to the valve core. The handle is fixedly connected to the other end of the steering shaft.

[0008] As a further improvement of this utility model, the number of the through pipes is provided in multiple sets, which are symmetrically arranged at multiple ends of the side wall of the valve body.

[0009] As a further improvement of this utility model: the number of steering shafts, valve cores and handles are all provided in multiple sets, and the multiple sets of steering shafts are symmetrically arranged at multiple ends inside the sealing valve cover.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] In this invention, the operator rotates a handle, causing the steering shaft to rotate, which in turn rotates the valve core fixed to it within the multi-directional flow channel. This rotation changes the valve core's relative position to the multi-directional flow channel and the connecting pipes, enabling water flow to switch between different pipes. A sealing gasket at the bottom of the inner valve seat matches a sealing ring groove within the valve body, and a sealing gasket at the top matches a sealing ring groove at the bottom of the sealing valve cover, preventing water leakage from the connection points. Connecting flanges one and two not only secure the valve body, valve seat mechanism, and switching mechanism, ensuring structural stability, but also facilitate disassembly and installation. When components malfunction or need replacement, removing the bolts allows for quick operation, improving maintenance efficiency. The valve core's different positions within the multi-directional flow channel connect it to different pipes, changing the water flow direction and on / off combinations. The operator rotates the handle to control the valve core's rotation angle, switching between different positions to meet the needs of water flow switching, diversion, or merging.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0020] Reference Figures 1 to 5 In this embodiment of the utility model, a multi-position reversing valve includes: a valve body 1, a valve seat mechanism 2 inside the valve body 1, a reversing mechanism 3 on the top of the valve body 1, a through pipe 4 fixedly connected to the side wall of the valve body 1, a sealing ring groove 5 opened at the bottom inside the valve body 1, a connecting flange 6 fixedly connected to the upper outside of the valve body 1, and multiple sets of through pipes 4 symmetrically arranged at multiple ends of the side wall of the valve body 1.

[0021] Reference Figure 1 , Figure 2 and Figure 4 The valve seat mechanism 2 includes an inner valve seat 201 and a multi-directional flow channel 202. The inner valve seat 201 is movably inserted into the valve body 1, and the multi-directional flow channel 202 is opened inside the inner valve seat 201. There are two sealing gaskets: a first sealing gasket 203 and a second sealing gasket 204. The first sealing gasket 203 is fixedly connected to one bottom end of the inner valve seat 201, and the second sealing gasket 204 is fixedly connected to one top end of the inner valve seat 201. The first sealing ring groove 5 is adapted to the first sealing gasket 203.

[0022] Reference Figure 1 and Figure 5 The reversing mechanism 3 includes a sealing valve cover 301, a second sealing ring groove 302, and a second connecting flange 303. The second sealing ring groove 302 starts at one bottom end of the sealing valve cover 301, and the second connecting flange 303 is fixedly connected to the lower outer side of the sealing valve cover 301. The second sealing ring groove 302 is adapted to the second sealing gasket 204. The mechanism also includes a steering shaft 304, a valve core 305, and a handle 306. The steering shaft 304 is rotatably connected inside the sealing valve cover 301, and both ends of the steering shaft 304 extend to the outside of the sealing valve cover 301. The valve core 305 is rotatably connected to the inner side of the multi-directional flow channel 202. One end of the steering shaft 304 passes through the inner valve seat 201 and is fixedly connected to the valve core 305. The handle 306... 06 is fixedly connected to the other end of the steering shaft 304. There are multiple sets of steering shaft 304, valve core 305 and handle 306. Multiple sets of steering shaft 304 are symmetrically arranged at multiple ends inside the sealing valve cover 301. When the operator rotates the handle 306, this action drives the steering shaft 304 to rotate synchronously. Since the valve core 305 is fixedly connected to the steering shaft 304, the rotation of the steering shaft 304 will drive the valve core 305 to rotate in the multi-directional flow channel 202. As the valve core 305 rotates, its relative positional relationship with the multi-directional flow channel 202 and the through pipe 4 on the valve body 1 changes, thereby enabling the water flow to switch directions between different through pipes 4.

[0023] The working principle of this utility model is as follows: During equipment operation, the operator rotates the handle 306, which drives the steering shaft 304 to rotate synchronously. Since the valve core 305 is fixedly connected to the steering shaft 304, the rotation of the steering shaft 304 will drive the valve core 305 to rotate within the multi-directional flow channel 202. As the valve core 305 rotates, its relative positional relationship with the multi-directional flow channel 202 and the through pipe 4 on the valve body 1 changes, thereby enabling water flow to be realized between different through pipes 4. Reversing; to ensure the system's sealing performance and prevent water leakage, the sealing gasket 203 at the bottom of the inner valve seat 201 is matched with the sealing ring groove 5 at the bottom of the valve body 1, and the sealing gasket 204 at the top of the inner valve seat 201 is also tightly fitted with the sealing ring groove 302 at the bottom of the sealing valve cover 301. This sealing structure acts as a solid defense, effectively preventing water leakage from the connection between the valve seat mechanism 2 and the valve body 1 and the reversing mechanism 3. Regarding installation and maintenance, the connecting flange... The connecting flange 303 plays a crucial role. It not only securely holds the valve body 1, valve seat mechanism 2, and reversing mechanism 3 together, ensuring the structural stability of the entire reversing valve, but also facilitates disassembly and installation. When the valve seat mechanism 2 or reversing mechanism 3 malfunctions or needs replacement, the corresponding component can be quickly replaced by disassembling the bolts and other connecting parts on the connecting flange, greatly improving maintenance efficiency. When the valve core 305 rotates within the multi-directional flow channel 202, it forms different position states. In each specific position state, the valve core 305 connects the multi-directional flow channel 202 to different pipes 4, thereby changing the flow direction and on / off combination of the water. Each flow direction and on / off combination corresponds to a specific gear position. The operator controls the rotation angle of the valve core 305 by rotating the handle 306, thus switching to different gear positions to meet different water flow reversing needs, such as achieving water flow switching between different pipes, water flow diversion, or water flow merging.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
