Description

Technical Field

[0001] This utility model relates to the field of multi-way valve technology, and more specifically, to a multi-way valve switching mechanism with high response speed. Background Technology

[0002] A multi-way valve is a key component in a hydraulic control system, primarily used to control the direction, flow, and pressure of multiple actuators. It employs a unified modular design, providing reliable system solutions for engineering vehicle manufacturers. The valve body can be configured in different ways to meet functional requirements, ranging from a simple load-sensitive manual multi-way valve to an electro-hydraulic proportional control valve with non-saturation functionality, independent of load and pump flow. This design makes the multi-way valve both simple and reliable, enabling different fluid control schemes based on specific application needs, including flow splitting and merging functions, allowing fluid to switch between different channels. By changing the position and opening degree of internal valves, multi-way valves achieve fluid splitting and control, and are widely used in industrial control systems.

[0003] However, the existing device has the following problems; Existing high-response-speed multi-way valve switching mechanisms are cumbersome because in real-world applications, multi-way valves require switching between different outlet pipes. Furthermore, existing devices require different operations to complete the switching process, making them cumbersome and thus affecting the switching efficiency of multi-way valves.

[0004] Therefore, in order to solve the above-mentioned technical problems, this application proposes a multi-way valve switching mechanism with high response speed. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a high-response-speed multi-way valve switching mechanism to solve the problem mentioned in the background art regarding the high-response-speed multi-way valve switching mechanism in the prior art. In real life, multi-way valves need to switch between different water outlet pipes during use, and existing devices require different operations to complete the switching work, which makes the operation of existing devices cumbersome and affects the switching efficiency of multi-way valves.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-response-speed multi-way valve switching mechanism, comprising an equipment multi-way valve, a delivery pipe, a delivery pipe on one side of the multi-way valve, and an output pipe on the other side of the multi-way valve, an anti-backflow mechanism inside the output pipe, a first fixing ring inside the anti-backflow mechanism, a second fixing ring on one side of the first fixing ring, a limiting rod on one side of the second fixing ring, and a piston between the first fixing ring and the second fixing ring, a support rod on the piston, and a rubber pad on one side of the piston, a switching mechanism inside the multi-way valve, a first rotating block inside the switching mechanism, a first transmission rod on one side of the first rotating block, a first ball valve on the first transmission rod, a first water outlet pipe at the bottom of the multi-way valve, and a second water outlet pipe on one side of the first water outlet pipe.

[0007] Preferably, a sleeve is movably mounted on the outer side of the first transmission rod, a first threaded ring is rotatably mounted on the sleeve, a first sliding sleeve is provided on one side of the first threaded ring, the first sliding sleeve is movably mounted on the sleeve, and a first vertical rod is fixedly mounted on one side of the first sliding sleeve.

[0008] Preferably, a second ball valve is provided on the first vertical rod, the second ball valve is movably installed in the multi-way valve, and a first spring is provided on one side of the first sliding sleeve, the first spring being movably installed on the sleeve.

[0009] Preferably, a second threaded ring is movably installed on the sleeve, a second sliding sleeve is provided on one side of the second threaded ring, the second sliding sleeve is movably installed on the sleeve, and a second vertical rod is fixedly installed on one side of the second sliding sleeve. A third ball valve is provided on the second vertical rod, and the third ball valve is movably installed inside the multi-way valve.

[0010] Preferably, a second spring is provided on one side of the second sliding sleeve, the second spring is movably mounted on the sleeve, a second rotating block is provided on one side of the output pipe, a second transmission rod is rotatably mounted on one side of the second rotating block, a fourth ball valve is provided on the second transmission rod, and the fourth ball valve is movably mounted inside the output pipe.

[0011] Preferably, the first fixing ring is fixedly installed inside the output pipe, the second fixing ring is fixedly installed inside the output pipe, and the first fixing ring and the second fixing ring are connected by a limiting rod. The piston is movably installed between the first fixing ring and the second fixing ring, the support rod is fixedly installed on the piston, and the rubber pad is fixedly installed on the piston.

[0012] Preferably, the first rotating block is fixedly mounted on the first transmission rod, one end of the first transmission rod passes through the sleeve and is rotatably mounted inside the multi-way valve, the first ball valve is movably mounted on the first transmission rod, and the first outlet pipe and the second outlet pipe are fixedly mounted at the bottom of the multi-way valve.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In this utility model, a switching mechanism is provided, which allows for the switching of different water outlet pipes. When the first water outlet pipe needs to be switched, the first rotating block in the mechanism drives the first transmission rod to rotate, thereby driving the first ball valve to rotate and sealing the middle of the multi-way valve. Then, the second screw ring rotates, which drives the second sliding sleeve to slide on the sleeve through the second spring. The second sliding sleeve then drives the second vertical rod to move, thereby moving the bottom of the third ball valve away from the first water outlet pipe, allowing the first water outlet pipe to be used. When the second water outlet pipe needs to be used, the first screw ring rotates, which drives the first sliding sleeve to move through the first spring. The first sliding sleeve then drives the first vertical rod to move, thereby moving the second ball valve away from the second water outlet pipe. Then, the second rotating block rotates, which drives the second transmission rod to rotate and seals the output pipe through the fourth ball valve, allowing water to flow out from the second water outlet pipe, thus improving the practicality of the device.

[0014] 2. In this utility model, by setting an anti-backflow mechanism, the water in the output pipe can be prevented from flowing back. The first and second fixed rings in the mechanism cooperate with each other and limit the piston through the limiting rod. When the backflow water pressure pushes the piston to one side, it will block the second fixed ring. This process can be sealed by a rubber gasket. When water needs to be discharged from the output pipe, the piston can be pushed towards the first fixed ring by the water pressure. This process can be supported by the support rod so that the water can flow out normally, thereby improving the working efficiency of the device. Attached Figure Description
