Description

Technical Field

[0001] This application relates to the technical field of valves, and particularly to a multifunctional integrated ball valve that is easy to maintain. Background Art

[0002] A ball valve is a common type of valve, and its main function is to control the flow of fluids (such as water, gas, oil, etc.) in a pipeline system. The multifunctional integrated ball valve that is easy to maintain is derived from its internal spherical closing member, which is usually composed of a sphere with holes. When the holes of the sphere are aligned with the axis of the pipeline, the fluid can flow freely; when the sphere rotates 90 degrees and the holes are perpendicular to the pipeline axis, the fluid flow is blocked, thereby realizing the opening and closing of the valve.

[0003] In the related art, reference can be made to the Chinese utility model patent with the authorization announcement number CN209469818U, which discloses a ball valve and its ball valve assembly. A ball valve includes a valve body, a valve core, and a valve stem. The outer wall of the valve body is provided with a convex portion. The valve core is arranged inside the valve body. One end of the valve stem is connected to the valve core, and the other end passes through the convex portion. The ball valve further includes a limit cover, a locking mechanism, and a limiting structure. The end of the valve stem passing through the convex portion is connected to the limit cover. The limit cover can rotate relative to the convex portion. A locking hole is provided on the limit cover. The locking mechanism is arranged between the limit cover and the convex portion for cooperating with the locking hole; the limiting structure is arranged on the convex portion for limiting the rotation angle of the limit cover relative to the convex portion.

[0004] During the actual working process of the above ball valve, the fluid flowing through the inside of the ball valve will more or less carry some impurities. These impurities will not only have an adverse impact on the operation of downstream equipment, but also adhere and accumulate inside the ball valve, thereby causing blockage of the ball valve. Summary of the Utility Model

[0005] In order to ensure the smooth flow of the ball valve and extend the service life of the ball valve, this application provides a multifunctional integrated ball valve that is easy to maintain.

[0006] A multifunctional integrated ball valve that is easy to maintain provided by this application adopts the following technical solutions:

[0007] A multifunctional integrated ball valve that is easy to maintain includes a valve housing, a valve stem, and a valve core arranged on the valve housing. An installation mechanism is arranged on the valve housing. A filter block is detachably arranged on the valve housing through the installation mechanism. A plurality of filter holes suitable for the fluid to pass through are provided on the filter block, and the filter block filters out impurities in the fluid.

[0008] By adopting the above technical solution, the filter block is detachably installed on the valve housing through the installation mechanism. The filter block filters the fluid flowing inside the valve housing, filters out the impurities in the fluid, thereby reducing the probability of the impurities blocking the valve core, ensuring smooth circulation inside the ball valve, extending the service life of the ball valve, and by removing the filter block through the installation mechanism, the filter block can be removed from the valve housing for cleaning the impurities, so that the filter block can be reused repeatedly and the maintenance is convenient and fast.

[0009] Optionally, the installation mechanism includes:

[0010] A first installation block and a second installation block. Clamping grooves are formed on both the first installation block and the second installation block. The first installation block and the second installation block respectively clamp the top and bottom of the filter block through the clamping grooves;

[0011] An installation screw. The installation screw passes through the first installation block and is threadedly connected to the second installation block. The head of the installation screw abuts against the first installation block;

[0012] A positioning component. An installation groove is formed on the valve housing. The first installation block and the second installation block are both inserted into the installation groove. The positioning component is arranged on the valve housing and is used for fixing the position of the first installation block in the installation groove.

[0013] By adopting the above technical solution, the first installation block and the second installation block are provided. The first installation block and the second installation block are inserted at both ends of the filter block, and the installation screw is used to tighten the first installation block and the second installation block. Then, the first installation block and the second installation block are inserted into the installation groove and fixed by the positioning component, thus completing the installation of the filter block on the valve housing. The filter block is installed in the form of the first installation block and the second installation block. Therefore, when facing different fluids, different filter blocks with different filter holes can be replaced by loosening the installation screw, and when moving the filter block in and out of the installation groove, neither the staff nor the valve housing will be in direct contact with the filter block, reducing the probability of damage to the filter block and ensuring the filtering effect of the filter block.

[0014] Optionally, the positioning component includes:

[0015] A positioning plate. The positioning plate is arranged on the valve housing and abuts against the lower surface of the first installation block;

[0016] A positioning block. A horizontal sliding groove is formed on the inner side wall of the installation groove. The positioning block is slidably arranged in the sliding groove;

[0017] A positioning spring. The positioning spring is arranged on the bottom wall of the sliding groove and is connected to the positioning block. The head of the positioning block protrudes out of the sliding groove under the action of the positioning spring and abuts against the upper surface of the first installation block.

[0018] By adopting the above technical solution, the positioning plate is installed on the valve housing below the first mounting block. Under the action of the positioning spring, the head of the positioning block penetrates out of the sliding groove and abuts against the upper surface of the first mounting block. The positioning plate and the positioning block cooperate to clamp and fix the first mounting block, thereby completing the fixing work of the position of the filter block by fixing the first mounting block.

[0019] Optionally, an arc-shaped guiding surface is provided at one end of the positioning block that penetrates out of the sliding groove.

[0020] By adopting the above technical solution, an arc-shaped guiding surface is provided at one end of the positioning block that penetrates out of the sliding groove. When the first mounting block is moved into the mounting groove, the first mounting block will first contact the guiding surface, and the guiding surface will generate a component force that drives the positioning block to move into the sliding groove. Thus, there is no need to manually squeeze the positioning block into the sliding groove, simplifying the working steps and improving the working efficiency.

[0021] Optionally, a pressure sensor is provided inside the valve housing, an indicator light is provided on the valve housing, and a controller is provided on the valve housing. The controller is connected to both the pressure sensor and the indicator light.

[0022] By adopting the above technical solution, a pressure sensor is installed inside the valve housing. The pressure sensor senses the fluid pressure after passing through the filter block and converts the sensed pressure signal into an electrical signal and transmits it to the controller. When the pressure signal sensed by the pressure sensor is lower than the normal value, it means that the filter block is blocked by impurities more seriously. Then the controller controls the indicator light to turn on, reminding the user to take out the filter block in time for replacement or cleaning, thus ensuring the normal use of the ball valve.

[0023] Optionally, an inclined water guiding surface is provided at the plate end of the positioning plate, and a rubber sealing ring is provided on the positioning plate.

[0024] By adopting the above technical solution, an inclined water guiding surface is provided at the plate end of the positioning plate, thereby reducing the resistance generated by the positioning plate to the fluid when it contacts the fluid and ensuring the smooth flow of the fluid inside the ball valve. A rubber sealing ring is installed on the positioning plate, thereby improving the sealing performance between the positioning plate and the first mounting block and reducing the probability of fluid leakage from the mounting groove.

[0025] Optionally, a handle is provided on the first mounting block.

[0026] By adopting the above technical solution, a handle is installed on the first mounting block, so that the user only needs to pull the handle when taking out the first mounting block from the mounting groove, which is convenient and practical.

[0027] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] 1. By detachably installing a filter block on the valve housing through an installation mechanism, the filter block filters the fluid flowing inside the valve housing, filters out impurities in the fluid, thereby reducing the probability of impurities clogging the valve core, ensuring smooth flow inside the ball valve, extending the service life of the ball valve, and by removing the filter block through the installation mechanism, the filter block can be taken off the valve housing for impurity cleaning work, enabling the filter block to be reused repeatedly and facilitating quick and easy maintenance;

[0029] 2. By providing an arc-shaped guiding surface at one end of the positioning block protruding out of the sliding groove, when the first mounting block is moved into the mounting groove, the first mounting block will first come into contact with the guiding surface, and the guiding surface will generate a component force that drives the positioning block into the sliding groove, thus eliminating the need for manual squeezing of the positioning block into the sliding groove, simplifying the working steps and improving work efficiency;

[0030] 3. By providing an inclined water guiding surface at the end of the positioning plate, the resistance generated by the positioning plate against the fluid when in contact with the fluid is reduced, ensuring smooth flow of the fluid inside the ball valve. A rubber sealing ring is installed on the positioning plate to improve the sealing performance between the positioning plate and the first mounting block, reducing the probability of fluid leakage from the mounting groove.
