Abstract
Description
Technical Field
[0001] The invention relates to the technical field of valve cores, in particular to a valve core sealing component of a regulating valve capable of withstanding high pressure difference. Background Art
[0002] The valve core is a part that the valve body uses to achieve the basic functions of direction control, pressure control or flow control. The valve core is divided into rotary type (45°, 90°, 180°, 360°) and translation type (radial, oriented) according to the movement mode. According to the shape, it can be generally divided into spherical (ball valve), conical (plug), round cake (butterfly valve and gate valve), round cover (stop valve and check valve) and cylindrical (reversing valve). The valve core is generally made of bronze or stainless steel, but there are also plastics, nylon, ceramics, glass and other materials. The valve core in the pressure reducing valve is one of the main components for achieving pressure control.
[0003] Most existing valve cores are used as switches for the inlet and outlet of faucets and to control the amount of water flow. They can only withstand relatively low pressure (such as 1.0Mpa). For example, when the faucet is used less late at night or when there is high pressure in some high-pressure areas, the faucet cannot withstand the high pressure and causes water leakage and bursting, causing safety accidents, thus posing a safety hazard.
[0004] Therefore, those skilled in the art provide a valve core sealing assembly of a regulating valve capable of withstanding high pressure difference to solve the problems raised in the above background technology. Summary of the invention
[0005] The object of the present invention is to provide a valve core sealing assembly of a regulating valve capable of withstanding high pressure difference, so as to solve the problems raised in the above-mentioned background technology.
[0006] In order to achieve the above-mentioned invention object, the present invention adopts the following technical scheme:
[0007] The present invention provides a valve core sealing assembly of a regulating valve capable of withstanding high pressure difference, comprising a valve core body, sealing rings being equidistantly arranged on the outer top of the valve core body, sealing gaskets being equidistantly arranged on the outer bottom of the valve core body, a silicone pad being arranged below the valve core body, a pair of sliding grooves being symmetrically provided on both sides of the bottom end surface of the valve core body, a sliding plate being slidingly provided inside each sliding groove, a first spring being elastically connected between the sliding plate and the inner top wall of the sliding groove, a limiting plate being adapted for the sliding plate being provided on the inner side wall of the bottom of the sliding groove, and a connecting plate connected to the silicone pad being fixedly connected to the side of the sliding plate away from the first spring.
[0008] Preferably, a fixing groove is provided at the axis center of the bottom surface of the valve core body, fixing columns are equidistantly provided on the inner top wall of the fixing groove, a fixing block is snap-connected to the inner cavity of the fixing groove, a fixing hole for plugging into the fixing column is provided on the surface of the fixing block, and a first buffer pad is provided between the fixing columns and fits with the inner top wall of the fixing groove.
[0009] Preferably, the outer wall of the valve core body is provided with an anti-rust layer, and the middle part of the valve core body is provided with an annular pressure-reducing groove.
[0010] Preferably, a threaded hole is provided at the top axis of the valve core body, a threaded column is threadedly connected to the threaded hole, and a socket adapted to the valve stem is provided at the surface axis of the threaded column.
[0011] Preferably, a group of second springs are symmetrically arranged on the inner hole wall of the insertion hole, and each group of the second springs is elastically connected to a fixing plate abutting against the valve stem.

It can withstand relatively high pressure (such as above 2.0Mpa), can resist the strong pressure brought by the water flow and has a self-locking function. In addition, the device itself adopts sealing gaskets, sealing rings and silicone pads to seal and wrap the outer wall of the valve core. As the water pressure increases, the spring force increases, which makes the silicone pad wrap the valve core tighter, and the sealing between the two is better, and the overall high-pressure resistance of the valve core is higher.

[0030] As shown in the attached figure of the instruction manual Figure 1-Figure 7As shown, the present invention provides a valve core sealing assembly of a regulating valve capable of withstanding high pressure difference, comprising a valve core body 1, a sealing ring 2 is equidistantly arranged on the outer top of the valve core body 1, a sealing gasket 3 is equidistantly arranged on the outer bottom of the valve core body 1, a silicone pad 4 is arranged below the valve core body 1, a pair of sliding grooves 5 are symmetrically provided on both sides of the bottom end surface of the valve core body 1, a sliding plate 6 is slidably arranged inside each sliding groove 5, a first spring 7 is elastically connected between the sliding plate 6 and the inner top wall of the sliding groove 5, a limiting plate 8 matched with the sliding plate 6 is provided on the bottom inner side wall of the sliding groove 5, the limiting plate 8 can limit the sliding trajectory of the sliding plate 6 in the sliding groove 5 to prevent it from sliding out of the sliding groove 5, and a connecting plate 9 connected to the silicone pad 4 is fixedly connected to the side of the sliding plate 6 away from the first spring 7, as shown in FIG. Figure 1 , Figure 2 As shown, the present invention can realize the functions of the valve core itself to switch and control the water flow, and can also withstand high pressure. It can withstand relatively high pressure (such as above 2.0Mpa), and can resist the strong pressure brought by the water flow and has a self-locking function. In addition, the device itself uses a sealing gasket 3, a sealing ring 2 and a silicone pad 4 to seal the outer wall of the valve core. As the water pressure increases, the spring force increases, which makes the silicone pad 4 wrap the valve core tighter, and the sealing between the two is better, and the overall high-pressure resistance of the valve core is higher.
[0031] As a preferred embodiment of the present invention, preferably, Figure 3 As shown, a fixing groove 10 is provided at the axis center of the bottom surface of the valve core body 1, and fixing columns 11 are equidistantly provided on the inner top wall of the fixing groove 10. A fixing block 12 is snap-connected to the inner cavity of the fixing groove 10, and a fixing hole 13 which is plugged into the fixing column 11 is provided on the surface of the fixing block 12. A first buffer pad 14 which fits the inner top wall of the fixing groove 10 is provided between the fixing columns 11. In specific implementation, when the silicone pad 4 needs to completely seal and wrap the valve core body 1, the middle part of the silicone pad 4 is squeezed by hand, the fixing block 12 is inserted into the fixing groove 10, and the fixing column 11 is inserted into the fixing hole 13 on the fixing block 12 to realize double locking of the silicone pad 4 on the valve core body 1, and the sealing and wrapping is more firmly performed. The setting of the first buffer pad 14 can prevent the fixing block 12 from passing through the fixing column 11 and contacting the inner wall of the fixing groove 10, thereby reducing the wear between the two.
[0032] As a preferred embodiment of the present invention, preferably, Figure 1As shown, the outer wall of the valve core body 1 is provided with an anti-rust layer 15, and an annular pressure reducing groove 16 is opened in the middle of the valve core body 1. The anti-rust layer 15 is coated with an anti-rust material to prevent the valve core body 1 from being corroded, worn and rusted by water due to being soaked in water for too long. In addition, the pressure reducing groove 16 allows more water to flow to the vicinity of the annular pressure reducing groove 16, thereby increasing the water flow rate in the pressure reducing groove 16 and improving the interception effect of the valve core body 1. In addition, the provision of the pressure reducing groove 16 can also reduce the weight of the valve core body 1, thereby achieving the effect of reducing materials and costs.
[0033] As a preferred embodiment of the present invention, preferably, Figure 1 As shown, a threaded hole 17 is provided at the top axis of the valve core body 1, and a threaded column 18 is threadedly connected to the threaded hole 17. A socket 19 compatible with the valve stem (not shown) is provided at the surface axis of the threaded column 18. During specific implementation, the valve stem is directly inserted into the threaded column 18, and the valve stem and the valve core body 1 are spliced through the threaded connection between the threaded column 18 and the threaded hole 17, which facilitates the subsequent control of the valve core body 1 by the valve stem and facilitates the disassembly and assembly between the two, thereby improving ease of use.
[0034] As a preferred solution of the present invention, in order to improve the plugging stability of the valve stem in the plug hole 19, it is preferred that Figure 1 , Figure 5 As shown, a group of second springs 20 are symmetrically arranged on the inner hole wall of the socket 19, and each group of second springs 20 is elastically connected to a fixing plate 21 abutting against the valve stem. The elastic expansion and contraction of the second springs 20 pushes the fixing plate 21 to contact the outer wall of the valve stem and abut against it, thereby achieving fixed clamping thereof.
[0035] As a preferred embodiment of the present invention, preferably, Figure 4 As shown, a placement plate 22 is symmetrically arranged on the outer side of the threaded column 18, and a threaded barrel 23 is movably arranged on the placement plate 22. The threaded barrel 23 is threadedly connected to a threaded rod 24, and a control handle 25 is fixedly connected to the top end of the threaded rod 24, and a positioning block 26 is fixedly connected to the bottom end of the threaded rod 24. A positioning groove 27 matched with the positioning block 26 is arranged on the outer side of the top surface of the valve core body 1. During specific implementation, the valve core body 1 is controlled by the valve stem to rotate forward and reverse to perform the flow interception work of the valve seat. When the valve core body 1 is adjusted to a certain angle for flow interception, in order to prevent accidental loosening, the control handle 25 is used to control the threaded rod 24 to rotate in the threaded barrel 23, so that the positioning block 26 is embedded in the positioning groove 27 for locking.
[0036] As a preferred embodiment of the present invention, preferably, Figure 4As shown, a placement hole 28 matched with the threaded tube 23 is provided on the surface of the placement plate 22, and a second buffer pad 29 matched with the outer wall of the threaded tube 23 is provided on the hole wall of the placement hole 28. In specific implementation, the second buffer pad 29 is first placed in the placement hole 28, and then the threaded tube 23 together with the threaded rod 24 are placed in the placement hole 28. The provision of the second buffer pad 29 can reduce the wear between the buffer tube and the placement hole 28, thereby improving the working service life and safety performance of both.
[0037] Working principle:
[0038] As shown in the attached figure of the instruction manual Figure 1-Figure 7 As shown, first, the valve stem is inserted into the insertion hole 19 of the threaded column 18, and the valve stem is elastically clamped by the second spring 20 and the fixing plate 21. Then, the threaded column 18 is installed on the valve core body 1 through the threaded hole 17, and the valve core body 1 is inserted into the interception port in the valve seat by means of the valve stem. The valve core body 1 is controlled to intercept the valve seat by the valve stem lifting or reversing. Normal valve operation, when the valve core body 1 is rotating to intercept, the valve core body 1 is sealed by the sealing gasket 3, the sealing and the silicone pad 4 to prevent water seepage and overflow in the valve seat. As the water flow increases, the first spring 7 is controlled by the water pressure to elastically wrap the silicone pad 4 around the valve core body 1, further providing a higher sealing effect. The greater the water inlet pressure, the greater the elastic potential energy of the first spring 7, and the higher the sealing performance, thereby achieving the high pressure resistance of the valve core body 1 itself. When the valve core body 1 is rotated, the threaded rod 24 is controlled to rotate in the threaded barrel 23 by the control handle 25, so that the positioning block 26 is embedded in the positioning groove 27 for locking.
[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
