Description

Technical Field

[0001] The utility model relates to the technical field of metal ball valves, in particular to a metal ball valve for reducing the friction of the sealing surface. Background Technique

[0002] A metal ball valve is a commonly used valve, and its characteristic is that the valve core is spherical. Its sealing material is a metal material, so it is suitable for environments with high temperature, high pressure and corrosive media. The metal ball valve is mainly used to cut off or connect the medium in the pipeline, and can also be used for the regulation of fluids.

[0003] The existing Chinese utility model patent with the reference publication number of CN210265983 discloses a metal ball valve, which includes a housing. The inner wall of the housing is welded with a valve body. A sphere is in contact with the inside of the valve body. The top of the sphere is welded with a valve stem. The top of the housing is welded with a valve cover. The top end of the valve stem sequentially penetrates through the valve body, the housing and the valve cover and extends to the outside of the valve cover and is bolted with a handle. Through the settings of the housing, the valve body, the sphere, the valve stem, the valve cover, the handle, the metal pipe, the baffle plate, the first pressing plate, the connecting pipe, the second pressing plate, the flange plate, the accessory box and the screw rod, the ball valve can convert different sealing modes according to different installation situations, achieving the advantage of good sealing performance. At the same time, it solves the problem that when the existing ball valve is installed with the pipe body, most of its sealing components are made of non-metal materials. However, in special cases, the non-metal sealing components will be greatly worn and corroded after long-term use, greatly reducing the sealing performance of the sealing components, thus causing leakage accidents.

[0004] When the existing metal ball valve is in use, the sealing surface is prone to friction. Therefore, after long-term use, the sealing effect is likely to become worse due to the deepening of friction, resulting in leakage problems, which affects the use of the metal valve ball. Content of the Utility Model

[0005] The purpose of the utility model is to overcome the problem that the existing technology has that the sealing surface is easily affected by friction and the sealing effect is reduced, and provides a metal ball valve for reducing the friction of the sealing surface.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A metal ball valve for reducing the friction of the sealing surface includes:

[0010] In a preferred embodiment, a lifter is fixedly installed on the top of the lifting groove. A lifting rod is movably connected inside the lifter. The lifting rod is a structure for lifting through the lifter.

[0011] In a preferred embodiment, a buckle is fixedly installed on one side of the lifting rod. The buckle is a structure for limiting and fixing.

[0012] In a preferred embodiment, two connecting pipes are fixedly installed on both sides of the valve body. A conveying pipe is fixedly installed on one side of the connecting pipe. The conveying pipe is a structure for conveying.

[0013] In a preferred embodiment, a connecting flange is fixedly installed on one side of the conveying pipe. A connecting ring is fixedly installed inside the connecting pipe. The connecting ring is a structure for connection.

[0014] In a preferred embodiment, four connecting holes are fixedly installed around the inside of the connecting ring. A silica gel ring is fixedly installed on one side inside the connecting hole. The silica gel ring is a structure for sealing.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. For this metal ball valve that reduces the friction of the sealing surface, the support ring can be supported by the support rod on one side of the installation plate. The support rod can be sealed by the silica gel ring. The outer side of the support ring can be wrapped by the ceramic sealing layer, thereby improving the wear resistance of this metal ball valve that reduces the friction of the sealing surface.

And the friction can be reduced by the smooth ceramic sealing layer;

[0017] 2. The metal ball valve that reduces the friction of the sealing surface can drive the support rod to move to one side inside the sealing ring through the contraction of the contraction rod, thereby driving the support ring to move. When the metal ball valve body rotates, there will be no friction between the ceramic sealing layers, thus reducing the friction of the sealing surface. The spring can play a buffering effect during sealing, avoiding the problem of damage to the sealing surface caused by excessive extrusion friction force. The insertion groove limits the insertion column, so that when the telescopic rod expands and contracts, the spring can be prevented from being straightened, improving the practicability of the metal ball valve that reduces the friction of the sealing surface and the effect of reducing friction.

[0030] On one side of the delivery pipe 21, a connecting flange 22 is fixedly installed, and inside the connecting pipe 2, a connecting ring 23 is fixedly installed.

[0031] Around the inside of the connecting ring 23, four connecting holes 24 are fixedly installed. On one side inside the connecting hole 24, a silica gel ring 25 is fixedly installed.

[0032] Specifically, through the connecting flange 22, the pipes can be connected. Through the delivery pipe 21, conveying can be carried out. Through the connecting pipe 2, the connecting ring 23 can be supported, and through the connecting hole 24, the telescopic rod 3 and the silica gel ring 25 can be supported.

[0033] On both sides of the valve body 1, telescopic rods 3 are movably connected. On one side of the telescopic rod 3, a connecting plate 31 is fixedly installed. On one side of the connecting plate 31, a spring 32 is fixedly installed. On one side inside the spring 32, an insertion groove 33 is fixedly installed, and inside the insertion groove 33, an insertion post 34 is movably connected.

[0034] Specifically, through the contraction of the telescopic rod 3, the connecting plate 31 can be driven to move to one side. Through the spring 32, a buffering effect can be achieved. Through the insertion groove 33, the insertion post 34 can be limited, avoiding the problem of the spring 32 being straightened.

[0035] On one side of the spring 32, a mounting plate 4 is fixedly installed. On one side of the mounting plate 4, a support rod 41 is fixedly installed. On one side of the support rod 41, a support ring 42 is fixedly installed. The support ring 42 is in a ring shape. On one side of the support ring 42, a ceramic sealing layer 43 is fixedly installed. On one side of the ceramic sealing layer 43, a silica gel sealing ring 44 is fixedly installed. The silica gel sealing ring 44 is in a ring shape.

[0037] Working principle: First, connect the metal ball valve that reduces the friction of the sealing surface to the pipeline through two connecting flanges 22. The operation of the lifter 13 can drive the lifting rod 14 to lift inside the lifting groove 12. The snap 15 can drive the metal ball valve body 11 to rotate, so as to seal the two sides of the valve body 1. The metal ball valve body 11 is attached to the ceramic sealing layer 43 on one side of the two support rings 42 on both sides, so as to achieve hard sealing. The silicone sealing ring 44 on the outer side of the ceramic sealing layer 43 can be attached to the metal ball valve body 11 for soft sealing, thereby improving the sealing effect of the metal ball valve that reduces the friction of the sealing surface. The ceramic sealing layer 43 can reduce the friction of the sealing surface of the metal ball valve body 11. Through the contraction of the spring 32, a buffering effect can be achieved, avoiding the problem of damage caused by severe friction of the sealing surface, improving the practicability of the metal ball valve that reduces the friction of the sealing surface and the effect of reducing friction. Through the contraction of the telescopic rod 3, the connecting plate 31 can be driven to move to one side inside the connecting hole 24. The insertion column 34 inside it can be limited through the insertion groove 33, avoiding the problem that the spring 32 is straightened due to the contraction of the telescopic rod 3, and improving the stability of the metal ball valve that reduces the friction of the sealing surface. Through the contraction of the telescopic rod 3, the support rod 41 can be moved to one side, so that the support ring 42 can be separated from the valve body 1, avoiding the problem of friction between the metal ball valve body 11 and the ceramic sealing layer 43 when the metal ball valve that reduces the friction of the sealing surface is opened and closed, improving the practicability of the metal ball valve that reduces the friction of the sealing surface and the effect of reducing friction. By wrapping the outer side of the support rod 41 with the silicone ring 25, a sealing effect can be achieved, avoiding liquid from entering the inside of the connecting hole 24. At the same time, the support rod 41 can move inside the silicone ring 25, improving the practicability of the metal ball valve that reduces the friction of the sealing surface.
