[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to their functions, they can be divided into shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid conveying systems and have functions such as shut-off, regulation, diversion, prevention of backflow, pressure stabilization, diversion or overflow pressure relief.

[0003] A Chinese patent application CN201920324967.3 discloses a stable valve actuator, the key points of its technical solution are: by providing a cylinder controller and electrically connecting it to the signal receiving end, when using it, the user only needs to use the cylinder button on the control handle, and transmit the operation instructions of the cylinder button to the power cylinder through the signal transmitting end, so as to control the lifting and lowering of the valve sealing head, and then cooperate with the sealing force pad to seal the entire pipeline, so as to help users easily control the valve actuator by wireless means, and avoid the tedious opening or closing of valves installed in dark places or deep places.

[0004] In view of the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when the staff operates the actuator process, they often use an operating lever to operate it, so that the operating lever rotates up and down in the actuator body. At this time, after the operating lever is rotated out of the actuator body, moisture remains on the arc surface of the operating lever, causing the arc surface of the operating lever to be corroded by the moisture, thereby causing the operating lever to be damaged and affecting the use of the staff; therefore, a corrosion-resistant valve actuator is proposed to address the above problems.

[0008] Preferably, the arc surface of the round rod is sleeved with a first spring, and two ends of the first spring are fixedly connected to the round rod and the U-shaped frame respectively.

[0026] Reference Figure 1 As shown, the utility model provides a technical solution: a corrosion-resistant valve actuator, comprising an actuator body 1, an operating rod 2 is installed on the surface of the actuator body 1, connecting rings 3 are installed on both sides of the actuator body 1, and a wiping device 4 is provided on the arc surface of the operating rod 2. By setting the wiping device 4, the arc surface of the operating rod 2 is wiped, and it is avoided that after the operating rod 2 is rotated out of the actuator body 1, there is residual moisture on the arc surface of the operating rod 2, resulting in the arc surface of the operating rod 2 being corroded by moisture, thereby causing damage to the operating rod 2 and affecting the use of the staff, thereby improving the practicality of the device, and the arc surfaces of the two connecting rings 3 are provided with sealing devices 5. By setting the sealing devices 5, the effect of increasing the sealing when the connecting ring 3 is connected to the external water pipe is achieved, and it is avoided that when the connecting ring 3 is connected to the external water pipe, a small amount of water overflows, resulting in a small amount of water contacting the screws of the connecting ring 3, resulting in corrosion of the screws of the connecting ring 3, thereby improving the practicality of the device.

[0027] The specific arrangement and function of the wiping device 4 and the sealing device 5 will be described in detail below.

[0028] Reference Figure 2 and Figure 3As shown, in this embodiment: the wiping device 4 includes a U-shaped frame 41, the U-shaped frame 41 is slidably connected to the arc surface of the operating rod 2, the lower surface of the U-shaped frame 41 is fixedly connected to the actuator body 1, and two round rods 42 are slidably inserted in the U-shaped frame 41. The two round rods 42 are fixedly connected to a wiping plate 43 on one side close to each other, and the two wiping plates 43 are slidably connected to a wiping pad 44 on one side close to each other. The wiping pad 44 is fixedly connected to two plug plates 48 on one side close to the wiping plate 43. The surface of the plug plate 48 is slidably connected to the wiping plate 43. The arc surface of the round rod 42 A first spring 45 is sleeved, and the two ends of the first spring 45 are fixedly connected to the round rod 42 and the U-shaped frame 41 respectively. When the staff releases the round rod 42, the resilience of the first spring 45 drives the round rod 42 to slide in the U-shaped frame 41, and the round rod 42 drives the wiping plate 43 to move in the direction of the operating rod 2, and the wiping plate 43 drives the wiping pad 44 to approach the arc surface of the operating rod 2. At this time, the first spring 45 achieves the effect of automatically making the wiping pad 44 close to the arc surface of the operating rod 2, thereby increasing the friction between the wiping pad 44 and the arc surface of the operating rod 2, thereby improving the wiping effect of the wiping pad 44 As a result, the wiping plate 43 is fixedly connected to the two fixing plates 46 on one side away from the wiping pad 44, and a plug rod 47 is slidably inserted in the fixing plate 46. The arc surface of the plug rod 47 is slidably connected to the plug plate 48. When the staff needs to replace the wiping pad 44, the plug rod 47 is pulled to slide the plug rod 47 in the fixing plate 46. At this time, the plug rod 47 slides in the plug plate 48 until the plug rod 47 is separated from the plug plate 48. At this time, the wiping pad 44 is pulled, and the wiping pad 44 drives the plug plate 48 to slide out of the wiping plate 43. At this time, the staff can replace the wiping pad 44 to avoid In order to avoid the wiping pad 44 being damaged after long-term use, resulting in a decrease in the wiping effect of the wiping pad 44, thereby affecting the wiping of the operating rod 2 by the wiping pad 44, the arc surface of the plug rod 47 is covered with a second spring 49, and the two ends of the second spring 49 are respectively fixedly connected to the plug rod 47 and the fixing plate 46. When the staff releases the plug rod 47, the rebound force of the second spring 49 drives the plug rod 47 to slide in the fixing plate 46, and at the same time drives the plug rod 47 to be inserted into the plug plate 48. At this time, the second spring 49 improves the stability of the plug rod 47 when limiting the plug plate 48.

[0029] Reference Figure 4As shown, specifically, the sealing device 5 includes two rubber rings 51, and the two rubber rings 51 are respectively slidably connected to the arc surfaces of the two connecting rings 3. Two connecting pads 52 are fixedly connected to the inner surface of the rubber ring 51. One end of the two connecting pads 52 away from the rubber ring 51 is fixedly connected to a rubber pad 53, and one side of the rubber pad 53 is slidably connected to the connecting ring 3. The arc surface of the rubber ring 51 is slidably connected to an extrusion plate 54, and both sides of the extrusion plate 54 are fixedly connected to a sliding plate 55. Both sides of the rubber ring 51 are provided with sliding grooves, and the sliding plate 55 and the rubber ring 51 are fixedly connected. The inner surface of the sliding groove is slidably connected, and a handle 56 is fixedly connected to the surface of the extrusion plate 54. When the staff fits the rubber ring 51 with the connecting ring 3, the handle 56 is pulled, and the handle 56 drives the extrusion plate 54 to slide on the arc surface of the rubber ring 51. At the same time, the extrusion plate 54 drives the sliding plate 55 to slide in the sliding groove of the rubber ring 51. At this time, the effect of partially extruding the gas on the inner surface of the rubber ring 51 is achieved, so as to avoid the contact between the rubber ring 51 and the connecting ring 3. A large amount of gas will appear, which will affect the sealing effect of the rubber ring 51.

[0030] Working principle: when the staff needs to use the actuator body 1, they need to rotate the operating rod 2 to operate the switch of the actuator body 1. At this time, the operating rod 2 rotates upward or downward from the actuator body 1. At this time, the wiping pad 44 is close to the arc surface of the operating rod 2 under the action of the first spring 45. At this time, the water on the operating rod 2 is wiped by the wiping pad 44. At this time, the arc surface of the operating rod 2 is wiped, which avoids the arc surface of the operating rod 2 from being corroded by moisture after the operating rod 2 is rotated out of the actuator body 1, thereby causing the operating rod 2 to be damaged and affecting the use of the staff, thereby improving the practicality of the device. When the staff needs to replace the wiping pad 44, the staff pulls the plug rod 47 to make the plug rod 47 slide in the fixed plate 46, the second spring 49 is stretched, and the plug rod 47 slides in the plug plate 48 until the plug rod 47 is disengaged from the plug plate 48. At this time, the wiping pad 44 is pulled, and the wiping pad 44 drives the plug plate 48 to slide out of the wiping plate 43. At this time, the round rod 42 is pulled to make the round rod 42 slide in the U-shaped frame 41, and the first spring 45 is stretched. At this time, enough space is made for the wiping pad 44 to be replaced, thereby avoiding damage to the wiping pad 44 after long-term use, resulting in a decrease in the wiping effect of the wiping pad 44, thereby affecting the wiping of the operating rod 2 by the wiping pad 44.

[0031] When the staff needs to connect the connecting ring 3 with the water pipe, the water pipe is fitted with the surface of the connecting ring 3. At this time, the rubber pad 53 is located between the connecting ring 3 and the water pipe, and the rubber pad 53 will not affect the water outflow or water inflow of the connecting ring 3. At this time, the rubber ring 51 is simultaneously sleeved on the arc surface of the connecting ring 3 and the arc surface of the water pipe. At this time, the handle 56 is pulled, and the handle 56 drives the squeezing plate 54 to slide on the arc surface of the rubber ring 51, and at the same time, the squeezing plate 54 drives the sliding plate 55 to slide in the sliding groove of the rubber ring 51. At this time, the effect of increasing the sealing when the connecting ring 3 is connected to the external water pipe is achieved, which avoids a small amount of water overflowing when the connecting ring 3 is connected to the external water pipe, causing a small amount of water to contact the screws of the connecting ring 3, causing corrosion of the screws of the connecting ring 3, thereby improving the practicability of the device.
