Description

Technical Field

[0001] This utility model relates to the field of gate valve technology, specifically a valve body. Background Technology

[0002] The valve body is generally the component in a valve structure used to control fluid flow. The valve body is the main structural part of the valve, while the valve plate is a key component inside the valve, responsible for opening or closing the fluid passage.

[0003] The valve body is provided with a flow drain hole, and a sealing layer is provided at the valve plate and the contact position between the valve plate and the valve body. The drain hole is sealed by the fit between the valve plate and the valve body. The flow rate is controlled by the movement of the valve plate to control the diameter of the drain hole. However, the sealing components are generally fixed, which causes friction between the valve plate and the valve body during the opening and closing of the valve plate, resulting in gaps. Consequently, leakage is likely to occur when the valve plate is closed. Therefore, this application designs a valve body with improved sealing effect to solve this defect of the prior art.

[0022] As a preferred embodiment of this utility model, the extension and retraction distance of the first telescopic hose and the second telescopic hose is equal to the extension and retraction distance of the stainless steel spring.

[0023] By adopting the above technical solution, it is ensured that the first telescopic hose, the second telescopic hose, and the stainless steel spring can extend and retract synchronously.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1 to 3 In this embodiment, a valve body includes a valve body 1, a drain valve plate 2, a drain hole 3, a movable switch plate 4, a sealing ring 5, and an adjusting rod 6.

[0038] The outer side of the valve body 1 is connected to an inlet connector opposite to the blocking groove 12, and the outer side of the valve body 1 is connected to a drain connector opposite to the drain hole 3.

[0039] The inlet connector connects to the inlet pipe, and the outlet connector connects to the outlet pipe.

[0040] The valve body 1 is equipped with a drain valve plate 2, which is provided with a drain hole 3 for discharging water. The valve body 1 is equipped with a movable switch plate 4 that limits its vertical movement. A sealing ring 5 is installed and fixed on the outside of the movable switch plate 4, which is tightly fitted and sealed to the drain valve plate 2 and located outside the drain hole 3. The valve body 1 is threaded with an adjusting rod 6 that drives the movable switch plate 4 to move up and down.

[0041] It should be added that the length and width of the drain valve plate 2 are equal to the length and width of the inner cavity of the valve body 1. The sealing ring 5 is cuboid. A threaded cylinder is integrally connected to the valve body 1. By rotating the adjusting rod 6, the screws are screwed in and out of the threaded cylinder. At the same time, the valve body 1 moves the movable switch plate 4 vertically and linearly, which drives the movable switch plate 4 and the sealing ring 5 to move up and down synchronously, thereby changing the sealing area of ​​the drain hole 3 and controlling the flow rate of liquid discharged through the drain hole 3.

[0042] A telescopic flexible hose 7 located inside the sealing ring 5 is installed and fixed on the outer side of the movable switch plate 4. A sealing plate 8, which is tightly fitted and sealed to the drain valve plate 2 and located outside the drain hole 3, is installed and fixed on the other side of the telescopic flexible hose 7.

[0043] The diameter of the sealing plate 8 is larger than the diameter of the drain hole 3.

[0044] Please see Figures 4 to 6 In this embodiment, the movable switch plate 4 is provided with a blocking and buffering component that moves and is buffered by water pressure on the side near the water inlet end of the valve body 1.

[0045] It should be noted that the blocking and moving buffer assembly includes a blocking component and a moving buffer component.

[0046] The blocking component includes a blocking plate 11, on the side of the blocking plate 11 near the water inlet end of the valve body 1, a blocking groove 12 is provided.

[0047] The width of the baffle plate 11 is equal to the width of the inner cavity of the valve body 1, thereby increasing the contact area and blocking effect between the incoming liquid and the baffle plate 11.

[0048] The movable buffer includes multiple mounting slots 13 formed on the outside of the movable switch plate 4. The mounting slots 13 are distributed at the four right angles of the movable switch plate 4. A stainless steel spring 15 is installed and fixed in the mounting slot 13. A buffer rod 14 connected to the blocking plate 11 is installed and fixed at the other end of the stainless steel spring 15.

[0049] When the stainless steel spring 15 is in its naturally extended state, the buffer rod 14 and the mounting groove 13 are not separated.

[0050] Please see Figure 5 and Figure 7 In this embodiment, a connecting seal is provided between the blocking and moving buffer assembly and the sealing plate 8. The water pressure on the blocking and moving buffer assembly is transmitted to the sealing plate 8 through the connecting seal, and pushes the sealing plate 8 to always achieve a sealed state with the drain valve plate 2.

[0051] It should be noted that the connecting seal includes a plurality of perforations 9 arranged in a ring at equal intervals on the movable switch plate 4 and a plurality of connecting rods 10 installed on the outside of the blocking plate 11, passing through the perforations 9 and connected to the sealing plate 8.

[0052] Connecting rod 10 passes through perforation 9 in a one-to-one correspondence.

[0053] A flexible telescopic hose 16 located outside the connecting rod 10 is installed and fixed between the blocking plate 11 and the movable switch plate 4.

[0054] The extension and retraction distances of the first telescopic hose 7 and the second telescopic hose 16 are equal to the extension and retraction distances of the stainless steel spring 15.

[0055] The working principle of the above embodiments is as follows:

[0056] In use, the inlet and outlet connectors on the valve body 1 are connected to the inlet and outlet pipes respectively by tightening screws, so that liquid enters the valve body 1 through the inlet pipe and is effectively blocked by the blocking groove 12 on the baffle plate 11. Under pressure, the baffle plate 11 is pushed to move, which drives the buffer rod 14 to move and compress the stainless steel spring 15 to buffer the impact force, thus forming an effective protection against impact deformation of the baffle plate 11.

[0057] When the baffle plate 11 moves, it drives the sealing plate 8 on the connecting rod 10 to move. At the same time, the second telescopic hose 16 retracts and the first telescopic hose 7 extends, forming a seal to protect the connecting rod 10 and the sealing plate 8. This ensures that as the water pressure increases, the sealing effect between the sealing plate 8 and the drain valve plate 2 is better. Together with the sealing ring 5 on the movable switch plate 4, it enhances the sealing effect with the drain valve plate 2. This prevents the sealing plate 8 from acting as a second seal when the adjusting rod 6 moves the movable switch plate 4. It also ensures that when the surface of the sealing plate 8 is worn due to friction during movement, it will not affect the sealing effect of the sealing plate 8 on the drain valve plate 2.
