Description

Technical Field

[0001] The utility model belongs to the technical field of adjustable CPVC ball valves, and more specifically, particularly relates to an adjustable CPVC ball valve. Background Art

[0002] Adjustable CPVC ball valve is a valve used in piping systems. It has the characteristics of controlling fluid, regulating flow, corrosion resistance and high temperature resistance. It is used to accurately control fluid flow and is widely used.

[0003] Some current adjustable CPVC ball valves have the function of controlling fluid velocity and flow rate. However, when the fluid velocity decreases, impurities contained in the fluid are easy to adhere to the inner wall of the pipe. Long-term accumulation can easily cause pipe blockage and affect the flow of the fluid. When the valve is closed, a water hammer effect will occur inside the pipe, and the fluid will have a strong impact force on the ball valve, which can easily cause damage to the ball valve.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an adjustable CPVC ball valve is provided to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an adjustable CPVC ball valve, which is achieved by the following specific technical means:

[0006] A adjustable CPVC ball valve comprises a pipe body, a mounting head is installed on the upper end surface of the pipe body, a rotating shaft is rotatably connected in the mounting head, a ball valve body is installed on the bottom end of the rotating shaft passing through the top of the pipe body, a through groove is provided in the ball valve body, clamping grooves are provided on both sides of the through groove, a filter screen is installed in the through groove, movable grooves are provided on both sides of the filter screen close to a pair of clamping grooves, a limiting block 1 is movably connected in the movable groove, a clamping block is installed on one side of the limiting block 1, a slide groove 1 is provided on one side of the ball valve body, a slide groove 2 is provided on one side of the slide groove 1, a limiting block 2 is slidably connected in the slide groove 2, a transmission block is installed on one side of the limit block 2, and the other end of the transmission block passes through one side of the slide groove 2, extends into the slide groove 1 and is installed with a buffer block.

[0007] Furthermore, a replacement port is provided on one side of the tube body, and a sealing cover is installed on one side of the replacement port.

[0008] Furthermore, one end of the tube body is provided with an input port, and the other end of the tube body is provided with an output port.

[0009] Furthermore, a handle is installed on the top end of the rotating shaft.

[0010] Furthermore, a spring 1 is installed on one side of the movable groove, and the other end of the spring 1 is connected to one side of the limiting block 1.

[0011] Furthermore, a second spring is installed on one side of the second slide slot, and the other end of the second spring is connected to one side of the second limiting block.

[0012] Furthermore, a rotating block is installed on one side of the filter screen.

[0013] Furthermore, one side of the card block is a beveled surface, and the size of the card block matches that of the card slot.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] Through the coordinated use of the filter screen, the rotating block, the spring 1, the clamping block and the clamping slot, firstly, the handle is used to drive the rotating shaft to rotate, and the rotating shaft drives the ball valve body to rotate, so that the through slot moves to the position of the replacement port, the sealing cover is opened, and then the clamping block is pushed into the movable slot so that the filter screen can be pushed into the through slot. When the clamping block moves to the position of the clamping slot, under the action of the spring 1, the spring 1 pushes the clamping block into the clamping slot through the limit block 1, so that the filter screen can be fixed, and then the impurities in the fluid can be filtered through the filter screen to prevent the impurities from adhering to the inner wall of the pipe and causing blockage. When the filter screen needs to be replaced, the rotating block is rotated with the help of a tool, and the rotating block drives the filter screen to rotate. Since one side of the clamping block is a beveled surface, the filter screen can push the clamping block into the movable slot when it rotates, so that the filter screen can be quickly taken out, thereby achieving the purpose of quickly and conveniently replacing the filter screen.

[0016] Through the coordinated use of spring 2, transmission block and buffer block, when the ball valve body is closed, the fluid in the pipeline will produce a water hammer effect. At this time, the buffer block is facing the input port. When the fluid impacts the buffer block, the buffer block transmits the impact force to the transmission block, and the transmission block transmits the impact force to spring 2 through limit block 2. Spring 2 can buffer the impact force, thereby reducing the damage to the ball valve body caused by the impact force and extending the service life of the ball valve body.
