Description

[Technical Field]

[0001] This invention relates to the technical field of waterway switching, and in particular to a mechanical switch switching device. [Background Technology]

[0002] See Figure 1 In existing water valves, the mechanical drive unit is typically installed on the primary side of the water source along with the valve's main opening and closing mechanism to drive it. To withstand water pressure fluctuations on the primary side, the mechanical drive unit needs to withstand extreme water pressure, requiring a large spring force. Furthermore, existing water valve distributors independently switch water paths and flow diameters via mechanical devices or motors.

[0003] The above-mentioned water valve has the following disadvantages:

[0004] 1. The mechanical drive device has a large opening force and is subjected to primary water pressure. Once it leaks, the water will flow continuously because the primary side is also subjected to water hammer impact when the valve is opened and closed. Water hammer impact can easily cause the mechanical switch to fail, resulting in the valve being unable to close.

[0005] 2. Existing distributors are independent devices that switch water channels and flow rates separately via mechanical or motor switching. [Summary of the Invention]

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a mechanical switch switching device. When the water valve is switched on or off, the mechanical drive device will not be subjected to water hammer impact, and the opening force is small, making it easier to close the valve.

[0007] To achieve the above objectives, the present invention proposes a mechanical switch switching device, including a valve body, an inlet on the valve body, and multiple outlets. The inlet channel of the valve body is provided with a valve seat. The device also includes a main valve opening and closing device and a mechanical drive device. The main valve opening and closing device is located upstream of the main waterway of the valve body, and the mechanical drive device is located downstream of the main waterway of the valve body. The mechanical drive device is provided with a manual rotating shaft and a manual push rod. The manual rotating shaft and the manual push rod work together to apply a force to the main valve opening and closing device, causing it to move away from the valve seat and open the inlet.

[0008] Preferably, the device also includes a switching distributor, the outlet of which is connected to multiple water outlets. The mechanical drive device is linked with the water valve body opening and closing device and the switching distributor. When the manual rotating shaft rotates, it applies a force to the switching distributor to drive it to switch water paths and adjust the water path diameter.

[0009] Preferably, the switching distributor is provided with a pressure plate and a water outlet pipe. The pressure plate has a pressure plate opening, and the water outlet pipe has multiple water outlet adjustment angles that correspond one-to-one with each water outlet. The pressure plate is rotatably mounted on one side of the water outlet pipe. The pressure plate is linked with the manual rotating shaft to switch the opening and closing of the water outlet adjustment angle and adjust the opening degree of the water outlet adjustment angle.

[0010] Preferably, the head of the manual rotating shaft is connected to the pressure plate via a connector, and is used to apply a force to the pressure plate to drive it to change the relative position of the pressure plate opening and the water outlet adjustment angle.

[0011] Preferably, the manual rotary shaft has a cam structure and a concave-convex structure, and the manual push rod has a first protrusion structure that cooperates with the cam structure and a second protrusion structure that cooperates with the concave-convex structure. The manual rotary shaft applies a force to the manual push rod through the first protrusion structure, causing it to move away from the valve seat, and the manual rotary shaft applies a force to the manual push rod through the second protrusion structure, causing it to move closer to the valve seat.

[0012] Preferably, the water valve body opening and closing device is provided with a moving valve core, and a spring is provided at the end of the moving valve core facing away from the valve seat. The spring provides a force for the moving valve core to press against the valve seat and block the water inlet.

[0013] Preferably, the end of the moving valve core facing the valve seat is provided with sealing rubber.

[0014] Preferably, the water valve body opening and closing device and the switching distributor are connected through a pressure reducing device, the pressure reducing inlet of the pressure reducing device is connected to the outlet of the water valve body opening and closing device, and the pressure reducing outlet of the pressure reducing device is connected to the distributor inlet of the switching distributor.

[0015] The beneficial effects of this invention are:

[0016] 1. The mechanical drive unit is installed downstream of the water source and will not be subjected to water pressure when not in use, nor will it be subjected to water hammer impact when the water valve is opened or closed. The opening force of the mechanical drive unit is much smaller than that of existing technical solutions, and the water pressure makes it easier to close the valve.

[0017] 2. The main opening and closing devices of the distributor and water valve are both controlled by a single mechanical drive, which simplifies control and reduces costs.

[0018] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. [Attached Image Description]

Detailed Implementation Methods

[0028] See Figure 1 and Figure 5 The present invention discloses a mechanical switch switching device, comprising a valve body, an inlet 101 disposed on the valve body, and a plurality of outlets 102. A valve seat 103 is provided on the inlet channel of the valve body. The mechanical switch switching device further comprises a water valve body opening and closing device 10 and a mechanical drive device 20. The water valve body opening and closing device 10 is disposed upstream of the main water channel of the valve body, and the mechanical drive device 20 is disposed downstream of the main water channel of the valve body. The mechanical drive device 20 is provided with a manual rotating shaft 21 and a manual push rod 22. The manual rotating shaft 21 and the manual push rod 22 cooperate and link together. The manual push rod 22 applies a force to the water valve body opening and closing device 10, causing it to move away from the valve seat 103 and opening the inlet 101.

[0029] Further, see Figure 5 and Figure 6The mechanical drive device 20 uses a cam structure and a concave-convex structure to control the translation of the manual push rod 22. Specifically, the manual rotating shaft 21 has a cam structure and a concave-convex structure, and the manual push rod 22 has a first protrusion structure 221 that cooperates with the cam structure and a second protrusion structure 222 that cooperates with the concave-convex structure. The manual rotating shaft 21 applies a force to the manual push rod 22 through the first protrusion structure 221, causing it to move away from the valve seat 103. The manual rotating shaft 21 applies a force to the manual push rod 22 through the second protrusion structure 222, causing it to move closer to the valve seat 103. In this embodiment, the end of the manual push rod 22 has a drive chamber into which the cam structure and the concave-convex structure can extend. The inner side of the drive chamber has the first protrusion structure 221 and the second protrusion structure 222. A sealing ring 220 is also installed on the outside of the manual push rod 22 to improve the sealing of the connection and prevent liquid leakage.

[0030] Further, see Figure 5 The water valve body opening and closing device 10 is provided with a moving valve core 11. A spring 12 is provided at the end of the moving valve core 11 facing away from the valve seat 103. The spring 12 provides a force to press the moving valve core 11 against the valve seat 103, thus blocking the water inlet 101. In this embodiment, a sealing rubber 13 is provided at the end of the moving valve core 11 facing the valve seat 103 to ensure reliable sealing.

[0031] Example 2

[0032] See Figure 1 and Figure 5 In this embodiment, the mechanical switch switching device further includes a switching distributor 30 for switching water paths and changing the water path diameter, so that the mechanical drive device 20 can not only open and close the valve, but also switch the water path. Specifically, the outlet of the switching distributor 30 is connected to multiple water outlets 102. The mechanical drive device 20 is linked with the water valve body opening and closing device 10 and the switching distributor 30. When the manual rotating shaft 21 rotates, it applies a force to the switching distributor 30 to drive it to switch the water path and adjust the water path diameter.

[0033] Further, see Figure 5 , Figure 7 and Figure 8 The switching distributor 30 is provided with a pressure plate 31 and a water outlet pipe 32. The pressure plate 31 has a pressure plate opening 311, and the water outlet pipe 32 has a plurality of water outlet adjustment angles 321 that correspond one-to-one with each water outlet 102. The pressure plate 31 is rotatably mounted on one side of the water outlet pipe 32. The pressure plate 31 is linked with the manual rotating shaft 21 to switch the opening and closing of the water outlet adjustment angles 321 and to adjust the opening degree of the water outlet adjustment angles 321.

[0034] Further, see Figure 5 , Figure 7 and Figure 8 The head of the manual rotating shaft 21 is connected to the pressure plate 31 via a connector 23, and is used to apply a force to the pressure plate 31 to drive it to change the relative position of the pressure plate opening 311 and the water outlet adjustment angle 321. That is, by controlling the rotation of the pressure plate 31 on the plane of the water outlet pipe 32, the pressure plate opening 311 and the water outlet adjustment angle 321 are switched to different positions, which can switch to water outlet A 1021 or water outlet B 1022, and adjust the water passage diameter.

[0035] Example 3

[0036] See Figures 2 to 6 , Figure 9 Based on Embodiment 1 or Embodiment 2, this device can be used in conjunction with a pressure reducing device 40. Specifically, in this embodiment, the water valve body opening and closing device 10 and the switching distributor 30 are connected through the pressure reducing device 40. The pressure reducing inlet 400 of the pressure reducing device 40 is connected to the outlet of the water valve body opening and closing device 10, and the pressure reducing outlet 401 of the pressure reducing device 40 is connected to the distributor inlet 301 of the switching distributor 30. The water valve body opening and closing device 10 switches the water valve open and closes via a mechanical drive device 20. After the water valve is opened, it flows through the pressure reducing device 40, then into the switching distributor 30, and finally out from the outlet 102.

[0037] Working principle of the invention:

[0038] 1. The mechanical drive device 20 is connected to both the water valve body opening and closing device 10 and the switching distributor 30. The control of the water valve body opening and closing device 10 and the switching distributor 30 can be realized through one mechanical drive device 20, which simplifies the control and reduces costs.

[0039] 2. The mechanical drive device 20 is equipped with a manual rotating shaft 21 and a manual push rod 22. By rotating the manual rotating shaft 21, the manual push rod 22 can move forward or backward. The forward movement of the manual push rod 22 can push the moving valve core 11, causing the water valve body opening and closing device 10 to open. When the manual push rod 22 moves backward, the moving valve core 11 will be pressed against the sealing surface of the valve seat 103 by the spring 12, and the water valve body opening and closing device 10 will close.

[0040] 3. The head of the manual rotating shaft 21 is connected to the pressure plate 31 of the switching distributor 30 through the connector 23. By rotating the manual rotating shaft 21, the pressure plate 31 can be rotated, which will change the position of the pressure plate opening 311 and the water outlet adjustment angle 321 of the water outlet pipe 32, thereby realizing pipeline switching or diameter switching.

[0041] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
