Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a valve with adsorption and purification function. Background Technology

[0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, and regulate and control the parameters (temperature, pressure, and flow rate) of the transported medium. Based on their function, they can be classified as shut-off valves, check valves, regulating valves, etc. Valves are control components in fluid transport systems, possessing functions such as shut-off, regulation, flow diversion, backflow prevention, pressure stabilization, flow splitting, or overflow pressure relief. Valves used in fluid control systems range from the simplest shut-off valves to the various valves used in extremely complex automated control systems, with a wide variety of types and specifications.

[0003] For example, CN222297256U discloses a connecting valve, including a valve with a connector flange installed on its outer end, inner gaskets installed on the inner sides of both ends of the valve, a tapered connecting pipe installed on the outer side of the inner gaskets, and leak-proof gaskets arranged in an array on the outer side of the tapered connecting pipe. A connecting pipe is provided on the outer side of the valve, and a transition flange is installed on the outer end of the connecting pipe. A magnetic suction plate is installed on the inner end of the connecting pipe, and a connecting pipe sleeve is installed on one side of the magnetic suction plate on the outer side of the tapered connecting pipe. The leak-proof gaskets on the outer side of the tapered connecting pipe are squeezed and deformed by the connecting pipe sleeve to reduce the gap between the connecting pipe sleeve and the tapered connecting pipe. When water flows through the inside of the tapered connecting pipe, the water pressure increases, and when the water passes through the end of the tapered connecting pipe, the water flow rate increases, ensuring the waterproofness of the connection between the valve and the connecting pipe.

[0004] Although the aforementioned patent ensures the waterproofness of the valve and connecting pipe connection, the valve in the prior art does not have the function of adsorption and purification, and cannot adsorb and purify the fluid passing through the valve, thus reducing its practicality. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a valve with adsorption and purification function, which has the advantages of being able to adsorb and purify the fluid passing through the valve. This solves the problem that existing valves do not have adsorption and purification functions and cannot adsorb and purify the fluid passing through the valve, thus reducing their practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A valve with adsorption and purification function includes a valve body and a connector flange connecting the left and right sides of the valve body. A connecting shell is provided on the upper surface of the valve body, and a threaded cylinder is provided on the upper surface of the connecting shell. An adsorption mechanism is provided on the top wall of the valve body cavity, and a limiting component is provided on the top wall of the valve body cavity.

[0008] The adsorption mechanism includes a U-shaped frame fixed to the top wall of the valve body cavity. A filter frame is slidably inserted into the U-shaped frame. A first sealing rubber ring is fixed to the outside of the filter frame. From left to right, a coarse filter screen, an activated carbon filter screen, and a support screen are fixed inside the filter frame. A sealing cover is fixed to the lower surface of the valve body by bolts. A limit slot is opened on the upper surface of the sealing cover. The filter frame is slidably inserted into the limit slot.

[0009] Furthermore, the sealing cover includes a fixed cover, and a second sealing ring is fixed on the upper surface of the fixed cover, the upper surface of the second sealing ring abutting against the lower surface of the valve body.

[0010] Furthermore, the limiting assembly includes two baffles fixed to the top wall of the valve body cavity. Each of the left and right baffles has a limiting groove on its opposite side. Each of the left and right limiting grooves has a slider slidably connected inside. Each of the left and right sliders has a valve plug fixed on its opposite side. The upper surface of the valve plug is rotatably connected to a valve stem via a bearing. The lower surface of the valve plug abuts against the upper surface of the sealing cap. The front and back sides of the left and right baffles are fixedly connected to the front and back walls of the valve body cavity.

[0011] Furthermore, the valve plug includes a valve plate, and a sealing rubber sleeve is fixed to the outside of the valve plate.

[0012] Furthermore, the threaded cylinder has an internal threaded connection to a threaded rod, and a rotating handwheel is fixed to the top of the threaded rod.

[0013] Furthermore, a sliding hole is provided through the upper surface of the connecting housing, and a second sealing rubber ring is fixed on one side inside the sliding hole. The valve stem is slidably connected inside the second sealing rubber ring, and the top end of the valve stem is fixedly connected to the bottom end of the threaded rod. The threaded rod is slidably connected inside the sliding hole.

[0014] Furthermore, the slider moves linearly up and down inside the limiting groove.

[0015] Furthermore, the front and back sides of the U-shaped frame are fixedly connected to the front and back walls of the valve body's inner cavity.

[0016] Compared with the prior art, this utility model provides a valve with adsorption and purification function, which has the following beneficial effects:

[0017] 1. This valve with adsorption and purification function can effectively remove impurities and harmful substances from fluids through dual filtration of a coarse filter and an activated carbon filter, improving the purity of the fluid. The design of the filter frame and sealing cover makes it easy to disassemble and replace, allowing users to easily maintain and replace the filter, reducing maintenance costs. The design of the support mesh ensures the stability of the activated carbon filter under fluid pressure, extending the service life of the activated carbon filter.

[0018] 2. This valve with adsorption and purification function can achieve precise up-and-down movement of the valve plug through the cooperation of the threaded rod and threaded cylinder, thereby accurately controlling the opening and closing of the valve. The design of the limit groove and slider ensures the stability of the valve plug during the up-and-down movement, avoiding poor sealing caused by shaking or displacement. The tight fit between the valve plug and the sealing cover can effectively prevent fluid leakage and ensure the sealing performance of the valve. The valve can be opened and closed by manually turning the handwheel, which is simple and convenient to operate and suitable for various scenarios that require manual control.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1In this embodiment, a valve with adsorption and purification function includes a valve body 1 and a connector flange 2 connecting the left and right sides of the valve body 1. A connecting housing 3 is provided on the upper surface of the valve body 1, and a threaded cylinder 4 is provided on the upper surface of the connecting housing 3. An adsorption mechanism 5 is provided on the top wall of the inner cavity of the valve body 1, and a limiting component 6 is provided on the top wall of the inner cavity of the valve body 1.

[0026] In this embodiment, the threaded cylinder 4 is internally threaded with a threaded rod 7, and a rotating handwheel 8 is fixed at the top of the threaded rod 7.

[0027] Please see Figures 2 to 3 In this embodiment, the adsorption mechanism 5 includes a U-shaped frame 501 fixed to the top wall of the inner cavity of the valve body 1. A filter frame 502 is slidably inserted into the inside of the U-shaped frame 501. A first sealing rubber ring 503 is fixed to the outside of the filter frame 502. The first sealing rubber ring 503 can seal the connection between the filter frame 502 and the valve body 1. The front and back of the first sealing rubber ring 503 abut against the front and back walls of the inner cavity of the valve body 1. A flow groove is opened inside the valve body 1. From left to right, a coarse filter screen 504, an activated carbon filter screen 505, and a support screen 506 are fixed inside the filter frame 502. A sealing cover 507 is fixed to the lower surface of the valve body 1 by bolts. A limit slot is opened on the upper surface of the sealing cover 507. The filter frame 502 is slidably inserted into the inside of the limit slot.

[0028] Specifically, the sealing cover 507 includes a fixed cover, the upper surface of which is fixed with a second sealing ring, the upper surface of which abuts against the lower surface of the valve body 1, and the front and back sides of the U-shaped frame 501 are fixedly connected to the front and back walls of the inner cavity of the valve body 1.

[0029] It should be noted that the flanges 2 on the left and right sides can be connected to the fluid pipeline. When the fluid enters the valve body 1, the coarse filter 504 can filter the impurities in the fluid. Then, the activated carbon filter 505 can adsorb and purify the fluid. The support net 506 can support the activated carbon filter 505 to improve stability. By turning the bolts on the left and right sides of the lower surface of the sealing cover 507, the sealing cover 507 can be removed. Then, the filter frame 502 can be removed by pulling it down from the inside of the U-shaped frame 501. This allows for unblocking the inside of the valve body 1 and replacing the activated carbon filter 505.

[0030] Please see Figure 4In this embodiment, the limiting component 6 includes two baffles 601 fixed to the top wall of the inner cavity of the valve body 1. A limiting groove 602 is provided on the opposite side of the left and right baffles 601. A slider 603 is slidably connected inside the left and right limiting grooves 602. A valve plug 604 is fixed on the opposite side of the left and right sliders 603. A valve stem 605 is rotatably connected to the upper surface of the valve plug 604 through a bearing. The lower surface of the valve plug 604 abuts against the upper surface of the sealing cover 507. The front and back sides of the left and right baffles 601 are fixedly connected to the front and back walls of the inner cavity of the valve body 1.

[0031] Specifically, the valve plug 604 includes a valve plate, a sealing rubber sleeve fixed to the outside of the valve plate, the sealing rubber sleeve matching the gap inside the valve body 1 to achieve sealing, a sliding hole penetrating the upper surface of the connecting housing 3, a second sealing rubber ring fixed to one side inside the sliding hole, a valve stem 605 slidably connected inside the second sealing rubber ring, the gap between the second sealing rubber ring and the valve stem 605 is adapted, the top end of the valve stem 605 is fixedly connected to the bottom end of the threaded rod 7, the threaded rod 7 is slidably connected inside the sliding hole, the slider 603 moves linearly up and down inside the limiting slide groove 602, a moving hole penetrating the upper surface of the valve body 1, and the valve stem 605 is slidably connected inside the moving hole.

[0032] It should be noted that by turning the handwheel 8, the threaded rod 7 is driven to rotate inside the threaded cylinder 4 and move downward, which in turn drives the valve stem 605 to move downward inside the connecting housing 3, and then drives the valve plug 604 to move downward. When the valve plug 604 moves to abut against the upper surface of the sealing cover 507, the valve closes. The stability of the valve plug 604 moving up and down can be improved by the cooperation between the limiting slide grooves 602 on the left and right sides and the slider 603.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, the valve body 1 can be connected to the fluid pipeline via the flanges 2 on both sides. When the fluid enters the valve body 1, impurities in the fluid are filtered through the coarse filter 504. Then, the fluid is purified by adsorption through the activated carbon filter 505. The support net 506 supports the activated carbon filter 505, improving stability. The sealing cover 507 can be removed by turning the bolts on the left and right sides of its lower surface. Then, the filter frame 502 can be pulled downwards from inside the U-shaped frame 501 to remove the filter frame 502. 2. Disassemble the valve body 1 to unclog its internal parts and replace the activated carbon filter 505. By turning the handwheel 8, the threaded rod 7 rotates inside the threaded cylinder 4 and moves downward, causing the valve stem 605 to move downward inside the connecting housing 3. Then, the valve plug 604 moves downward. When the valve plug 604 moves to abut against the upper surface of the sealing cover 507, the valve closes. The stability of the valve plug 604 moving up and down is improved by the cooperation between the limiting slide grooves 602 on the left and right sides and the slider 603.
