Description

Technical Field

[0001] The utility model belongs to the technical field of valve bodies and relates to a sealing valve body component. Background Art

[0002] A ball valve is a valve whose opening and closing elements are driven by a valve stem and rotate around its axis. It can also be used for fluid regulation and control. Ball valves are categorized by actuation method as pneumatic, electric, and manual. Ball valves are widely used in industries such as petroleum refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electricity, municipal services, and steel. When the valve is open, the valve body and seat are fixed in position. Prolonged, hard friction between the valve core and the seat causes wear and tear, creating gaps. The medium flowing in the pipeline may leak through the gap between the valve core and the seat. Similarly, when the valve is closed, the gap between the valve core and the seat prevents a complete seal on the pipeline. Friction between the valve core and the seat reduces the valve core's service life and increases wear.

[0003] Application No. 202220086594.2 provides a high-sealing ball valve, belonging to the field of valve technology. The high-sealing ball valve includes a valve body main body, the top end of the valve body main body is fixedly connected to a valve cover, the valve body main body and the valve cover are rotatably connected with a sealing packing rod, the bottom end of the sealing packing rod is fixedly connected to a valve core, and the valve core is used to control the communication of the valve body main body; a handle is fixedly connected to the surface of the valve stem, and second grooves are provided on both sides of the valve body main body, and movable valve body bases are provided in the two second grooves. The movable valve body base is used to cooperate with the air cavity for sealing, and elastic components are provided on both sides of the valve body main body. The elastic components are used to drive the movable valve body base to make it more fit the circumferential surface of the valve core and provide a buffer space for the movable valve body base when the valve core rotates. The elasticity of the elastic component is used to drive the movable valve body base to compress the gap, so that the movable valve body base and the valve core can still be sealed, thereby effectively ensuring the sealing of the device.

[0004] Although the above-mentioned valve body structure is provided with an elastic component to provide a buffer space, when installing the elastic component, it is necessary to open multiple installation slots inside the valve body, and there are many improvements to the valve seat. In addition, during subsequent maintenance, the valve body base and the elastic component need to be maintained separately. It is not enough to simply disassemble the valve body base, and the cost of use is high. Summary of the Invention

[0005] The purpose of the present invention is to provide a sealing valve body component to solve the problems raised in the above background technology.

[0006] The objectives of the present utility model can be achieved through the following technical solutions: a sealing valve body component, comprising a valve seat, a mounting groove and a valve body base, mounting grooves are provided on both sides of the interior of the valve seat, a valve body base is installed inside the mounting groove, the valve body base is composed of an outer base, an inner base and a support block, an inner base is provided inside the outer base, and the outer base and the inner base are connected by a rubber sheet, four support blocks are provided on the side of the outer base, a support sheet is provided inside the support block, a strong spring is installed on one end of the support sheet, a spring support is provided on the side of the inner base, and one end of the strong spring is connected to the outside of the spring support.

[0007] In the above-mentioned sealing valve body component, a ball valve core is installed between the two valve body bases, a switch knob is installed on one side of the valve seat, and the bottom end of the switch knob is connected to the ball valve core through a valve stem.

[0008] In the above-mentioned sealing valve body, a sealing end surface is provided at a side position of the inner base, and two sealing strips are installed on the surface of the sealing end surface.

[0009] In the above-mentioned sealing valve body, cover plates are installed on the top and bottom of the valve seat, and the surfaces of the two cover plates are respectively installed with a water inlet port and a water outlet port.

[0010] In the above-mentioned sealing valve body component, a lead screw is installed on the internal thread of the support block, one end of the lead screw is connected to a mounting knob, and the other end of the lead screw is connected to a clamp.

[0011] In the above-mentioned sealing valve body, a limiting hole is provided on the inner wall surface of the installation groove, and the clamping head is clamped inside the limiting hole.

[0012] Compared with the prior art, the present application improves the existing valve body base and sets a valve body base structure consisting of an outer base and an inner base. The sealing end surface of the inner base is provided with multiple sealing strips. When the ball valve contacts the sealing end surface, a multi-channel sealing structure can be formed by the multiple sealing strips, thereby improving the sealing effect. At the same time, the inner base and the outer base of the present application are movable, and the inner base is elastically supported by four groups of support blocks. When the valve core rotates, the inner base can move toward the rear, thereby preventing large wear between the valve core and the valve body base during the rotation process. At the same time, the elastic setting of the inner base can make the inner base be pushed toward the valve core again after the valve core has completed the rotation, and fit against the surface of the valve core to achieve sealing. The present application does not require major changes to the valve seat. The improvements are all on the valve body base. During maintenance, there is no need to disassemble the internal parts of the valve seat. Only the valve body base needs to be replaced, which is simple and convenient.

[0013] There is a tiny gap, and the elasticity of the elastic component is used to drive the movable valve body base to compress the gap, so that the movable valve body base and the valve core can still be sealed, effectively ensuring the sealing of the device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0022] The sealing valve body comprises a valve seat 1, a mounting groove 4 and a valve body base 5. Mounting grooves 4 are provided on both sides of the interior of the valve seat 1. The valve body base 5 is installed inside the mounting groove 4. The valve body base 5 is composed of an outer base 9, an inner base 10 and a support block 6. The inner base 10 is provided inside the outer base 9. The outer base 9 and the inner base 10 are connected by a rubber sheet 11. Four support blocks 6 are provided on the side of the outer base 9. A support sheet 18 is provided inside the support block 6. A strong spring 12 is installed at one end of the support sheet 18. A spring support 15 is provided on the side of the inner base 10. One end of the strong spring 12 is connected to the outside of the spring support 15.

[0023] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the sealing valve body of the utility model, specifically, a ball valve core is installed between the two valve body bases 5, a switch knob 2 is installed on one side of the valve seat 1, and the bottom end of the switch knob 2 is connected to the ball valve core through the valve stem. By turning the switch knob 2, the valve core can be driven to rotate, thereby realizing the flow channel inside the valve seat 1.

[0024] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the sealing valve body of the present invention, specifically, a sealing end surface 13 is opened on the side of the inner base 10, and two sealing strips 14 are installed on the surface of the sealing end surface 13. The sealing strips 14 are rubber strips, and two are provided to form a two-line sealing structure.

[0025] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the utility model is a sealing valve body component. Specifically, a cover plate 3 is installed on the top and bottom of the valve seat 1, and a water inlet port and a water outlet port are installed on the surfaces of the two cover plates 3 respectively. The present application uses the water inlet port and the water outlet port for water intake and drainage. The cover plate 3 is a metal structure. When the cover plate 3 is opened, the valve body base 5 can be exposed, which facilitates the replacement of the valve body base 5.

[0026] like Figure 1 、 Figure 2 、 Figure 3 and Figure 6 As shown, the sealing valve body component of the present invention, specifically, the internal thread of the support block 6 is installed with a screw 16, one end of the screw 16 is connected to the installation knob 8, and the other end of the screw 16 is connected to the clamp 17. The clamp 17 of the present application is a metal structure, and four groups are provided, mainly used for the installation of the valve body base 5.

[0027] like Figure 1 、 Figure 2 and Figure 3 As shown, the sealing valve body component of the present invention, specifically, the inner wall surface of the installation groove 4 is provided with a limiting hole 7, and the clamping head 17 is clamped inside the limiting hole 7. There are four limiting holes 7, which are mainly used to fix and limit the valve body base 5.

[0028] The utility model is a sealing valve body component. When installing, open the cover plates 3 on both sides of the valve seat 1, and install the two valve body bases 5 in the corresponding installation grooves 4 respectively. Then turn the installation knob 8 to drive the screw 16 to rotate, so that the clamping head 17 at one end of the screw 16 extends out, and the clamping head 17 is stuck in the inside of the limiting hole 7, thereby completing the limiting of the valve body base 5, and then cover the cover plate 3 again. Since the sealing end face 13 of the inner base 10 of the present application is provided with multiple sealing strips 14, the sealing strips 14 are rubber strips. When one side of the valve core of the ball valve contacts the sealing end face 13, a multi-channel sealing structure can be formed by the multiple sealing strips 14, thereby improving the sealing effect at the valve core. At the same time, the inner base 10 and the outer base 9 of the present application are movable , and the inner base 10 is elastically supported by four groups of support blocks 6. When the valve core rotates, the valve core contacts the inner base 10. When the inner base 10 is subjected to force, the inner base 10 can move toward the rear, thereby preventing large wear between the valve core and the valve body base 5 during the rotational contact process. At the same time, the inner base 10 is elastically set, and a strong spring 12 provides thrust, so that after the valve core has completed its rotation, the inner base 10 will be pushed toward the valve core again. The inner base 10 fits against the surface of the valve core to achieve sealing. Even if there is a small gap, the strong spring 12 inside the support block 6 pushes the valve body base 5 to compress the gap, so that the valve body base 5 and the valve core can still be sealed, effectively ensuring the sealing of the device.
