Description

Technical Field

[0001] This utility model relates to the field of ball valve technology, specifically to an easy-to-assemble ball valve. Background Technology

[0002] A ball valve is a control valve widely used in fluid pipeline systems. It opens or closes the passage by rotating a ball around the valve body's axis. It features low flow resistance, good sealing performance, and easy operation, and is widely used in water supply and drainage, chemical, petroleum, and food processing industries. A typical ball valve mainly consists of a valve body, ball, stem, seals, and a drive mechanism (such as a handle or worm gear). The valve body forms a fluid passage, and the ball has a through-hole that matches the passage. The stem rotates the ball, aligning the through-hole with the valve body passage (open state) or offsetting it (closed state), thus controlling the flow of fluid. To prevent impurities (such as particles and debris) from entering the ball valve and causing ball jamming or wear on the sealing surface, and to extend the valve's service life, some ball valves are equipped with a filter assembly. This typically includes a filter screen and a fixed structure. The filter screen intercepts impurities, while the fixed structure installs the filter screen at the valve body's inlet or within the flow channel. Currently, the connection between the filter assembly and the valve body of ball valves is mostly achieved by bolt fastening or welding. When using bolt fastening, flanges or lugs need to be installed on the edge of the filter screen. During assembly, the bolt holes need to be aligned and the bolts tightened one by one, which is a cumbersome process and difficult to operate in confined spaces. When using welding, although the connection is strong, the filter screen cannot be disassembled and replaced after assembly, resulting in high maintenance costs. In addition, high-temperature welding can easily cause deformation of the valve body or filter screen, affecting the sealing performance. Therefore, an easily assembled ball valve is needed to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to provide an easy-to-assemble ball valve, which solves the problem that in the prior art, the connection between the filter component and the valve body of the ball valve is mostly fastened with bolts or welded. When using bolt fastening, flanges or lugs need to be set on the edge of the filter screen. During assembly, the bolt holes need to be aligned and the bolts tightened one by one, which is a cumbersome process and difficult to operate in a confined space. When using welding, although the connection is firm, the filter screen cannot be disassembled and replaced after assembly, resulting in high maintenance costs. In addition, high-temperature welding can easily cause deformation of the valve body or filter screen, affecting the sealing performance.

[0004] This utility model provides the following technical solution: an easily assembled ball valve, comprising a ball valve body, a mounting box fixedly connected to the side end of the ball valve body, an opening communicating with the ball valve body on the side end of the mounting box, a sealing cover on the top end of the mounting box, several insert boxes fixedly connected to the side end of the mounting box, several insert plates fixedly connected to the side end of the sealing cover, each insert plate having an installation groove inside, each installation groove having a limiting component for fixing the insert plate in the insert box, a filter box inserted inside the mounting box, and several circular grooves on the top end of the mounting box, each circular groove having a spring-loaded component for ejecting the sealing cover inside.

[0009] As a preferred embodiment of the above technical solution, a sealing gasket is fixedly connected to the bottom end of the sealing cover, and a plurality of insert rods are fixedly connected to the bottom end of the sealing cover.

[0010] As a preferred embodiment of the above technical solution, each of the aforementioned inserts is inserted into each circular groove, and each of the aforementioned inserts presses against the top of the circular plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes the cooperation between the insert plate and the insert box, along with the automatic locking structure of the limiting component, to fix the sealing cover without bolts. This avoids the tedious steps of aligning bolt holes and tightening them one by one, making it particularly suitable for operation in confined spaces.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0015] like Figures 1-5As shown, this utility model provides a technical solution: an easily assembled ball valve, including a ball valve body 1, a mounting box 2 fixedly connected to the side end of the ball valve body 1, a through-hole 201 communicating with the ball valve body 1 on the side end of the mounting box 2, a sealing cover 4 on the top end of the mounting box 2, several insert boxes 3 fixedly connected to the side end of the mounting box 2, several insert plates 5 fixedly connected to the side end of the sealing cover 4, each insert plate 5 having an installation groove 501 inside, each installation groove 501 having a limiting component 6 for fixing the insert plate 5 in the insert box 3, a filter box 7 inserted inside the mounting box 2, the filter box 7 having a multi-stage filter element installed inside, a rubber sealing ring 701 fixedly connected to the side end of the filter box 7, the rubber sealing ring 701 being inserted into the through-hole 201, a groove 702 on the top end of the filter box 7, and several circular grooves 202 on the top end of the mounting box 2, each circular groove 202 having a limiting component 6 inside. The spring-loaded assembly 801 for ejecting the sealing cover 4, through the cooperation of the insert plate 5 and the insert box 3 and the automatic locking structure of the limiting assembly 6, can fix the sealing cover 4 without bolt tightening, avoiding the tedious steps of aligning bolt holes and tightening them one by one. It is especially suitable for operation in confined spaces and solves the problem of troublesome assembly of traditional bolt connections. Pressing the locking plate 603 can release the fixation, and with the spring-loaded assembly 801, the sealing cover 4 automatically pops up, making it easy and quick to remove the filter box 7 for filter element replacement. Compared with the filter assembly fixed by welding, no destructive operation is required, which greatly reduces the difficulty and cost of maintenance. At the same time, it avoids the problem of valve body or filter screen deformation caused by welding. The double sealing design of the rubber sealing ring 701 and the sealing gasket 401, combined with the firm fixation of the locking plate 603, effectively prevents fluid leakage. The multi-stage filter element can efficiently intercept impurities, reduce wear between the ball and the sealing surface, extend the service life of the ball valve, and ensure the stable operation of the pipeline system.

[0016] As one implementation method in this embodiment, such as Figure 4 and Figure 5As shown, the limiting component 6 includes a spring 601, which is fixedly installed on the inner side of the mounting groove 501. A rectangular plate 602 is fixedly connected to the side of the spring 601, and a retaining plate 603 is fixedly connected to the side of the rectangular plate 602. The bottom of the retaining plate 603 is sloped. Each insert plate 5 is inserted into each insert box 3. Each insert box 3 has an insertion port 301 on its side. The retaining plate 603 is inserted into the insertion port 301. In practice, when assembling the filter assembly, the filter box 7 is inserted into the mounting box 2. The rubber sealing ring 701 on the side of the filter box 7 tightly fits the inner wall of the opening 201. This initial sealing process prevents fluid leakage. Then, the sealing cover 4 is placed on top, and the insert plate 5 on the side of the sealing cover 4 is inserted into the insert box 3 on the side of the mounting box 2. During the insertion process, the retaining plate 603 of the limiting component 6 inside the insert plate 5 is squeezed by the inner wall of the insert box 3 and compresses the spring 601 because the bottom end of the retaining plate 603 is sloping. When the retaining plate 603 moves to the insertion port 301 on the side of the insert box 3, the spring 601 resets and pushes the rectangular plate 602, causing the retaining plate 603 to pop out and insert into the insertion port 301, thus completing the fixation of the sealing cover 4 and the mounting box 2. At the same time, the sealing gasket 401 at the bottom of the sealing cover 4 further enhances the sealing performance.

[0017] As one implementation method in this embodiment, such as Figure 2 and Figure 3 As shown, the rebound assembly 801 includes a second spring 802, which is fixedly connected to the inner side of the circular groove 202. A circular plate 803 is fixedly connected to the top of the second spring 802. A sealing gasket 401 is fixedly connected to the bottom of the sealing cover 4. Several insert rods 402 are fixedly connected to the bottom of the sealing cover 4. Each insert rod 402 is inserted into each circular groove 202, and each insert rod 402 presses against the top of the circular plate 803. When maintaining or replacing the filter assembly, the insert rods are pressed into the side insertion port 301 of the insertion box 3. The clamping plate 603 compresses the spring 601, causing it to retract into the mounting groove 501 and release the fixing of the insert plate 5 to the insert box 3. At this time, the spring-loaded component 801 in the circular groove 202 at the top of the mounting box 2 begins to act. The spring 802 pushes the circular plate 803 upward to lift the insert rod 402 at the bottom of the sealing cover 4, causing the sealing cover 4 to automatically spring up. At this time, the sealing cover 4 can be easily opened. Then, the operator can easily remove it from the mounting box 2 through the pull groove 702 at the top of the filter box 7 for multi-stage filter replacement or cleaning.

[0018] Working principle: When assembling the filter assembly, the filter box 7 is inserted into the mounting box 2. The rubber sealing ring 701 on the side of the filter box 7 tightly fits the inner wall of the opening 201, achieving a preliminary seal to prevent fluid leakage. Then, the sealing cover 4 is put on, so that the insert plate 5 on the side of the sealing cover 4 is inserted into the insert box 3 on the side of the mounting box 2. During the insertion process, the retaining plate 603 of the limiting component 6 inside the insert plate 5, due to its sloping bottom end, is squeezed by the inner wall of the insert box 3 and compresses the spring 601. When the retaining plate 603 moves to the position of the insertion port 301 on the side of the insert box 3, the spring 601 resets and pushes the rectangular plate 602, causing the retaining plate 603 to pop out and insert into the insertion port 301, completing the connection between the sealing cover 4 and the mounting box 2. The sealing cover 4 is fixed in place, and the sealing gasket 401 at the bottom of the sealing cover 4 further enhances the sealing performance. When maintaining or replacing the filter components, press the retaining plate 603 in the insertion port 301 on the side of the insertion box 3, so that the retaining plate 603 compresses the spring 601 and retracts into the mounting groove 501, releasing the fixing of the insert plate 5 and the insertion box 3. At this time, the spring-loaded component 801 in the circular groove 202 at the top of the mounting box 2 starts to work. The spring 802 pushes the circular plate 803 upward to lift the insertion rod 402 at the bottom of the sealing cover 4, so that the sealing cover 4 automatically pops up. At this time, the sealing cover 4 can be easily opened. Then, the operator can easily take it out of the mounting box 2 through the pull groove 702 at the top of the filter box 7 for replacement or cleaning of the multi-stage filter element. During reinstallation, repeating the assembly steps above will complete a quick reset. During ball valve operation, fluid enters from the filter box 7, is filtered through multiple filter elements to remove impurities, and then enters the ball valve body 1 through the port 201. This prevents impurities from entering between the ball and valve body, causing jamming or wear, and ensures normal opening and closing of the ball valve. Through the cooperation of the slide plate 5 and the slide box 3, and the automatic locking structure of the limiting component 6, the sealing cover 4 can be fixed without bolts, avoiding the tedious steps of aligning bolt holes and tightening them one by one. This is especially suitable for operation in confined spaces and solves the problem of cumbersome assembly with traditional bolt connections. Pressing the retaining plate 603 releases the fixation, and the spring-loaded component 801 causes the sealing cover 4 to automatically pop up, facilitating quick and easy removal of the filter box 7 for filter element replacement. Compared to welded filter components, this eliminates the need for destructive operations, significantly reducing maintenance difficulty and costs. It also avoids the deformation of the valve body or filter screen caused by welding. The double sealing design of the rubber sealing ring 701 and the sealing gasket 401, combined with the firm fixation of the retaining plate 603, effectively prevents fluid leakage. The multi-stage filter element can efficiently intercept impurities, reduce wear between the ball and the sealing surface, extend the service life of the ball valve, and ensure the stable operation of the pipeline system.
