Description

Technical Field

[0001] The present application relates to the technical field of butterfly valves, and particularly relates to a wafer butterfly valve. Background Art

[0002] A butterfly valve, also called a flap valve, is a simple-structured regulating valve. A butterfly valve that can be used for the on-off control of a low-pressure pipeline medium refers to a valve in which the closing member (valve flap or butterfly plate) is a disc and rotates around the valve shaft to achieve opening and closing.

[0003] The valve can be used to control the flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil products, liquid metals, and radioactive media. It mainly functions as a cut-off and throttling on the pipeline. The opening and closing member of the butterfly valve is a disc-shaped butterfly plate that rotates around its own axis inside the valve body to achieve the purpose of opening and closing or regulating; However, when an ordinary butterfly valve is in use, it does not have a filtering function. And when a butterfly valve with a filtering function is in use, the filter plate is often immersed in the liquid, especially in a corrosive liquid, which greatly reduces the service life of the filter plate. For this reason, we propose a wafer butterfly valve. Summary of the Invention

A shift block is movably provided inside the limit frame, the left end of the shift block is fixedly connected to the rear end of the sealing plate, and the shift block extends to the outside of the limit frame.

[0008] Preferably, a spring is fixedly connected between one end of the shift block close to the side wall of the connecting ring and the inner side of the limiting frame.

[0009] Preferably, after the valve plate is rotated to 90 degrees to open the butterfly valve body, the shifting block is shifted to drive the sealing plate to move so that the through holes overlap.

Then, each graphite heating plate is started through an external switch, so that the graphite heating plate heats the stainless steel filter plate by thermal radiation to dry the stainless steel filter plate. After the set time is reached, the graphite heating plate is turned off, and the valve plate is completely closed.

Additionally, in this application, terms such as "comprising" and "including" mean "including but not limited to". In this application, relational terms such as "first" and "second" are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0023] As Figures 1-4 shown: An embodiment of this application provides a wafer butterfly valve, including: A butterfly valve body 1, the front end of the butterfly valve body 1 is fixedly connected with a partition connection housing 2 through a flange, and a partition plate mechanism 4 and a filtering mechanism 11 are fixedly connected inside the partition connection housing 2; The partition plate mechanism 4 includes a partition plate. A cavity 8 is opened inside the partition plate. A sealing plate 9 is movably inserted into the cavity 8. A sealing rubber layer 10 is fixedly provided at the left end of the sealing plate 9. A plurality of through holes 5 are uniformly formed through the partition plate, the sealing plate 9, and the sealing rubber layer 10; The filtering mechanism 11 includes a connecting ring. The left end of the connecting ring is fixedly connected to the outer side of the right end of the partition plate. Stainless steel filter plates 12 are fixedly connected to the left and right sides inside the connecting ring 11. Graphite heating plates 13 are uniformly fixedly provided between the stainless steel filter plates 12. After the graphite heating plates 13 are connected in series with each other, they are connected to a wiring terminal 3. The wiring terminal 3 is fixedly connected to the outer side of the partition connection housing 2.

[0024] As Figure 3 shown: A valve plate 18 is rotatably provided inside the butterfly valve body 1. A transmission rod 7 is fixedly inserted in the middle of the valve plate 18. The lower end of the transmission rod 7 is rotatably inserted into the lower part of the inner cavity of the butterfly valve body 1, and the upper part of the transmission rod 7 is rotatably and sealingly inserted into the inner cavity of an installation pipe 6. The installation pipe 6 is fixedly connected to the outer side of the butterfly valve body 1. The rotation of the transmission rod 7 drives the valve plate 18 to rotate.

[0025] Specifically, when the valve plate 18 is closed, the partition plate mechanism 4 is closed, and when the valve plate 18 is opened, the partition plate mechanism 4 is opened.

[0026] like Figure 3 As shown: a limit frame 17 is provided on the front right end of the partition plate mechanism 4, and the limit frame 17 also penetrates the filter mechanism 11. A shift block 16 is movably provided inside the limit frame 17, and the left end of the shift block 16 is fixedly connected to the rear end of the sealing plate 9, and the shift block 16 extends to the outside of the limit frame 17.

[0027] Specifically:.

[0028] like Figure 4 As shown, a spring 15 is fixedly connected between one end of the shift block 16 close to the side wall of the connecting ring 11 and the inner side of the limiting frame 17 .

[0029] Specifically: the spring 15 is in a compressed state.

[0030] like Figure 1 As shown: after the valve plate 18 is rotated to 90 degrees to open the butterfly valve body 1, the shifting block 16 is shifted to drive the sealing plate 9 to move so that the through holes 5 overlap.

[0031] Specifically, the through holes 5 overlap so that the through holes 5 are open.

[0032] like Figure 3 As shown: the outer side of the ink heating plate 13 is covered with a sealed protective shell, and the sealed protective shell is a heat-conducting shell.

[0033] Specifically, the ink heating plate 13 is a heating component.

[0034] like Figure 1 As shown: the upper part of the transmission rod 7 is connected with one of a controllable driving device and a manual handle.

[0035] like Figure 1 As shown: the connection terminal 3 is connected to an external power source through a wire and a switch.

[0036] Specifically: the connection terminal 3 is for connecting wires.

[0037] like Figure 3 As shown: after the through holes 5 of the sealing plate 9 are interlaced with the partition plate, all the through holes 5 are sealed.

[0038] like Figure 3 As shown: connecting plates 14 are fixedly connected between the graphite heating plates 13, and the outer connecting plates 14 are fixedly connected to the inner wall of the connecting ring.

[0039] Specifically, the graphite heating plate 13 adopts the existing heating plate on the market, which is the existing technology.

[0040] Principle of use: When the device is in use, if the valve plate 18 is in a closed state, the toggle block 16 will not be squeezed and toggled by the valve plate 18. Therefore, under the elastic force of the spring 15, the toggle block 16 can be reset, and then the sealing plate 9 can be reset, so that the through hole 5 of the sealing plate 9 intersects with the through hole 5 of the partition plate, thereby sealing the partition plate mechanism 4. At the same time, the valve plate 18 is not completely closed. Then, each graphite heating plate 13 is started through an external switch, so that the graphite heating plate 13 heats up and radiates heat to the stainless steel filter plate 12 to dry the stainless steel filter plate 12. After the set time arrives, the graphite heating plate 13 is turned off, and the valve plate 18 is completely closed. By setting the graphite heating plate 13, the stainless steel filter plate 12 can be dried after use and will not be immersed in the liquid, thereby increasing the service life of the stainless steel filter plate 12, especially for corrosive liquids. When the valve plate 18 is opened, the valve plate 18 will toggle the toggle block 16, and the toggle block 16 will drive the sealing plate 9 to displace, so that the through hole 5 of the sealing plate 9 coincides with the through hole 5 of the partition plate, thereby opening the partition plate mechanism 4, and the liquid will flow to the inner right side of the butterfly valve body 1 after being filtered by the stainless steel filter plate 12.

[0041] The above are only specific embodiments of the present application, which enable those skilled in the art to understand or implement the present application. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined in the present application can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown in the present application, but will conform to the widest scope consistent with the principles and novel features claimed in the present application.
