Description

Technical Field

[0001] The utility model relates to the technical field of gate valves, and more specifically to an adaptive flow control titanium alloy gate valve. Background Art

[0002] Titanium alloy gate valve is a high-performance valve type, which is particularly suitable for applications with strict requirements on corrosion resistance, strength and lightweight. Titanium alloy gate valves are usually compact in design, with smooth channels and low flow resistance, which helps to improve the efficiency of the system.

[0003] The existing titanium alloy gate valve is composed of a valve cover, a gate, a valve stem and a handwheel. When in use, when the valve stem is moved upward by the handwheel, the gate rises accordingly and separates from the valve seat, and the fluid channel is opened. At this time, the sealing surface between the gate and the valve seat is separated, ensuring unimpeded fluid passage.

[0004] In actual use of the prior art, since impurities such as sand may be mixed in the water flow, the sand may continuously hit the valve plate under the action of the water flow, causing increased wear on the valve plate surface and reducing the sealing performance of the valve. Therefore, an adaptive flow control titanium alloy gate valve is proposed. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] In view of the problems existing in the prior art, the utility model provides an adaptive flow control titanium alloy gate valve, which filters out impurities in the water flow through a filter screen to prevent sand in the water flow from moving and depositing on the sensitive elements of the sensor, causing blockage of the sensor pores and a decrease in sensing accuracy. At the same time, it prevents sand from constantly hitting the valve plate under the action of the water flow, causing increased wear on the valve plate surface, reducing the sealing performance of the valve and affecting the service life of the valve. The filter screen can be manually rotated to drive the limit block to rotate to the opening of the limit groove. At this time, the filter screen loses its fixed limit and can be removed, which is convenient for the operator to clean and replace it.

[0007] 2. Technical solution

[0008] To solve the above problems, the utility model adopts the following technical solutions.

[0009] An adaptive flow control titanium alloy gate valve comprises a valve body, connecting pipes are connected on both sides of the valve body, a valve cover is movably connected to the upper surface of the valve body, a filtering mechanism is provided at one end of the connecting pipe, and a control mechanism is provided in the inner cavity of the valve body; the filtering mechanism comprises a connecting flange fixedly connected to one end of the connecting pipe, a limiting groove is provided in the inner cavity of the connecting flange, and a filter screen is movably connected to the inner cavity of the limiting groove; the control mechanism comprises a valve plate movably connected to the inner cavity of the valve body, a threaded sleeve is fixedly connected to the upper surface of the valve plate, a screw is threadedly connected to the inner cavity of the screw sleeve, a rotating rod is fixedly connected to the upper end of the screw, and a fixing frame is rotatably connected to the outer surface of the rotating rod.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) This solution uses a filter to filter out impurities in the water flow, preventing sand in the water flow from moving and depositing on the sensitive elements of the sensor, causing the sensor pores to be blocked and the sensing accuracy to be reduced. At the same time, it prevents sand from constantly hitting the valve plate under the action of the water flow, causing the valve plate surface to be abraded, reducing the sealing performance of the valve and affecting the service life of the valve.

[0032] Furthermore, the connection flange 201 is used to connect and install with the external pipeline. When the water flows into the connecting pipe 101, the impurities in the water flow are first filtered out by the filter screen 203. The filter screen 203 can be manually rotated to drive the limit block 204 to rotate to the opening of the limit groove 202. At this time, the filter screen 203 loses its fixed limit and can be removed, which is convenient for the operator to clean and replace it.

[0033] Example 2

The inner cavity of the valve body 1 is provided with a control mechanism 3, including a valve plate 305 movably connected to the inner cavity of the valve body 1, a screw sleeve 306 is fixedly connected to the upper surface of the valve plate 305, a screw 308 is threadedly connected to the inner cavity of the screw sleeve 306, a rotating rod 309 is fixedly connected to the upper end of the screw 308, and a fixing frame 310 is rotatably connected to the outer surface of the rotating rod 309;

[0035] Specifically, a sensor 303 is fixedly connected to the inner wall of the connecting pipe 101, a controller 304 is fixedly connected to the upper surface of the valve cover 102, a motor 311 is fixedly connected to the upper surface of the fixing frame 310, the sensor 303 and the controller 304 are electrically connected, the controller 304 and the motor 311 are electrically connected, the valve plate 305 and the screw sleeve 306 move in the inner cavity of the valve cover 102, the lower end of the fixing frame 310 is fixedly connected to the upper surface of the valve cover 102, and the valve body 1 and the valve cover 102 are fixedly connected by the bolts 301 and the nuts 302;

At the same time, it is prevented that the sand will continuously hit the valve plate 305 under the action of the water flow, causing the surface wear of the valve plate to increase, reducing the sealing performance of the valve, and affecting the service life of the valve. The filter 203 can be driven by manual rotation to rotate the limit block 204 to the opening of the limit groove 202 At this time, the filter screen 203 loses its fixed limit and can be removed, which is convenient for the operator to clean and replace, and improves the convenience of the device when in use. When the water flows through the sensor 303, the water flow parameters will be monitored and the information will be transmitted to the controller 304. The controller 304 calculates the required valve opening according to the preset program or external instructions, and then drives the motor 311 to drive the rotating rod 309 and the screw rod 308 to rotate and drive the screw sleeve 306 and the valve plate 305 to move inside the valve body 1 and the valve cover 102, thereby automatically adjusting the position of the valve plate 305, realizing adaptive control of the water flow, ensuring the stability and accuracy of the flow, and reducing energy consumption.
