Description

Technical Field

[0001] This utility model relates to the field of flat gate valve technology, specifically to an electric flat gate valve. Background Technology

[0002] In the field of fluid transport and control, gate valves, as key fluid control devices, are widely used in various industrial pipeline systems to regulate the flow direction and flow rate of liquids or gases. The basic structure of a traditional gate valve typically consists of a valve body, a valve cover, and a gate plate installed inside the valve body. The valve is opened and closed by the up and down movement of the gate plate, thereby controlling the flow of fluid.

[0003] On the one hand, since the liquids or gases being transported often contain various impurities, these impurities tend to adhere to the gate plate when the fluid passes through the gate valve. As the usage time increases, more and more impurities accumulate on the gate plate, causing the valve to not open and close smoothly. When impurities adhere to the surface of the gate plate, the valve needs to be manually disassembled and cleaned periodically.

[0004] Although the above equipment can transport liquids and gases through electric flat gate valves, a large amount of liquids and gases accumulate at the electric flat gate valves after being transported through pipelines. If cleaning is required, under the current technology, the electric flat gate valve must be closed and disassembled before cleaning can be performed. Disassembly is time-consuming and cleaning is troublesome. Utility Model Content

[0005] In view of this, the present invention provides an electric flat gate valve, which can automatically scrape off attached impurities during the lifting and lowering process of the flat gate, thereby achieving self-cleaning.

[0006] To solve the above-mentioned technical problems, this utility model provides an electric flat gate valve, including a lower gate valve body and an upper gate valve body. The lower gate valve body is located at the bottom of the upper gate valve body. Flange fittings are provided on both sides of the lower gate valve body. A flat gate is slidably installed inside the lower and upper gate valve bodies. Cleaning components are provided on both sides of the inner wall of the lower gate valve body. The cleaning components include grooves on both sides of the inner wall, and cleaning blocks are installed in the grooves. That is, the gate valve opens or closes the fluid passage by controlling the raising and lowering of the flat gate. During normal operation, the gate is in the raised state, and the fluid enters from one side of the flange fittings and flows smoothly to the other side through the internal passage of the gate valve to realize fluid transmission. When closed, the gate descends and blocks the inlet and outlet of the flange fittings, cutting off the fluid flow, thereby controlling the flow direction and flow rate. In addition, the gate can automatically scrape off attached impurities during the raising and lowering process, realizing self-cleaning.

[0007] The cleaning component also includes protrusions on the cleaning block, the protruding parts of which are in contact with the plane of the flat gate; that is, the protrusions are used to clean the flat gate.

[0008] A rectangular frame 1 is provided on the top of the lower housing of the gate valve, and a rectangular frame 2 is provided on the top of the upper housing of the gate valve. The rectangular frame 2 and the rectangular frame 1 are fixed together by bolts, which facilitates the separation of the upper housing and the lower housing of the gate valve by personnel.

[0009] The sliding assembly also includes a rectangular frame block disposed at the end of the flat gate, with a rectangular frame groove provided inside the rectangular frame block located within the rectangular frame groove; thereby improving the stability of the flat gate.

[0010] The sliding assembly also includes a hydraulic telescopic rod disposed on the top of the upper housing of the gate valve, the telescopic end of which is connected to the top of the rectangular block; thereby facilitating the vertical movement of the rectangular block.

[0011] A rubber pad is provided at the bottom of the rectangular frame block; this serves to seal the rectangular frame groove and the rectangular frame block.

[0012] The cleaning block and the raised block are made of stainless steel, thus preventing the liquid from corroding them.

[0013] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0014] 1. First, the rectangular frame block is moved up and down by the hydraulic telescopic rod, so that when the flat gate slides between the lower and upper shells of the gate valve, the protrusions on the cleaning block come into contact with the flat gate, and the cleaning block can clean the impurities on the flat gate.

[0015] 2. When the rectangular frame block is moved downward by the hydraulic telescopic rod, it enters the rectangular frame groove on the rectangular frame, thereby improving the stability of the flat gate. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-5 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0026] like Figure 1-5 As shown: This embodiment provides an electric flat gate valve, including a lower gate valve housing 100 and an upper gate valve housing 102. The lower gate valve housing 100 is located at the bottom of the upper gate valve housing 102. Flange fittings 101 are provided on both sides of the lower gate valve housing 100. The flange fittings 101 are fixedly installed on the lower gate valve housing 100 by welding, and are used to guide liquids or gases. A sliding assembly 300 is slidably disposed inside the lower gate valve housing 100 and the upper gate valve housing 102. The sliding assembly 300 includes a flat gate 302 slidably disposed inside the lower gate valve housing 100 and the upper gate valve housing 102. When the sliding assembly 300 drives the flat gate 302 to move within the lower gate valve housing... The sliding assembly 100 and the upper housing 102 of the gate valve slide up and down inside, so that when the flat gate 302 moves down, it can block the liquid flange fitting 101. The inner walls of the lower housing 100 of the gate valve are provided with cleaning components 200. The cleaning components 200 include grooves 201 provided on both sides of the inner wall. The cleaning blocks 203 are provided in the grooves 201 and are fixedly installed in the grooves 201 by bolts. When the sliding assembly 300 drives the flat gate 302 to slide between the lower housing 100 and the upper housing 102 of the gate valve, the cleaning blocks 203 come into contact with the flat gate 302, so that the cleaning blocks 203 can clean the impurities on the flat gate 302.

[0027] Liquid or gas enters the lower housing 100 of the gate valve from one side of the flange fitting 101 and then flows out from the other side. This is the basic path of fluid transmission under normal operating conditions of the gate valve, indicating that the gate valve is in the open state, allowing fluid to pass smoothly. Personnel drive the sliding component 300 to move the parallel gate downward, thereby blocking the left and right ends of the flange fitting 101 and preventing the liquid or gas from flowing to the other end, thus realizing the gate valve's closing function and effectively controlling the flow direction and flow rate of the fluid. Because the transported liquid contains impurities, the impurities will stick to the flat gate 302. During the process of the drive component moving the flat gate 302 up and down, the impurities on the gate can be cleaned in the process, realizing the self-cleaning function.

[0028] Cleanup Component 200 Figure 3 Enlarged view of point B in the image Figure 5 As shown,

[0029] The cleaning component 200 also includes a protrusion 202 disposed on the cleaning block 203. The protrusion 202 is fixed to the cleaning block 203 by welding. The protruding part of the protrusion 202 contacts the plane of the flat gate 302, so that the protrusion 202 can scrape off the impurities on the flat gate 302.

[0033] The sliding assembly 300 also includes a rectangular frame block 301 disposed on the end of the flat gate 302. A rectangular frame groove 105 is provided in the rectangular frame 104. The rectangular frame block 301 is located in the rectangular frame groove 105, thereby allowing the flat gate 302 to move into the rectangular frame groove 105 in the rectangular frame 104, thereby providing support for the flat gate 302.

[0034] Sliding component 300, etc. Figure 2 As shown,

[0035] The sliding assembly 300 also includes a hydraulic telescopic rod 303 disposed on the top of the upper housing 102 of the gate valve. The telescopic end of the hydraulic telescopic rod 303 is connected to the top of the rectangular frame 301. The hydraulic telescopic rod 303 is fixedly installed on the upper housing 102 of the gate valve, thereby driving the rectangular frame 301 to move up and down.

[0036] A rubber pad is provided at the bottom of the rectangular block 301. The rubber pad is fixedly installed at the bottom of the rectangular block by means of adhesive, etc., so as to serve as a seal.

[0037] The cleaning block 203 and the protrusion block 202 are made of stainless steel, which reduces the corrosion of the cleaning block 203 and the protrusion block 202 by the liquid;
