Description

Technical Field

[0001] This utility model relates to the field of diaphragm valve technology, specifically to a diaphragm valve that is easy to process and install. Background Technology

[0002] A diaphragm valve is a shut-off valve that uses a diaphragm as the opening and closing element to close the flow path, cut off the fluid, and separate the valve body cavity from the valve cover cavity. Diaphragms are commonly made of materials such as rubber and plastic. They have a simple structure, good sealing and corrosion resistance, and low fluid resistance. They are used for low-pressure, low-temperature, highly corrosive, and media containing suspended matter.

[0003] A diaphragm valve with authorization announcement number CN218494254U, which is easy to process and install, includes: a valve body; a cylinder assembly; a diaphragm, wherein the diaphragm is disposed on the valve body, and the cylinder assembly is disposed on the side of the diaphragm away from the valve body; and a valve core, wherein the valve core includes several sub-valve cores arranged in a circle, and the valve core has a first receiving groove, into which the diaphragm is snapped. By having several sub-valve cores arranged in a circle to form the valve core and the diaphragm snapped into the first receiving groove, the valve core and diaphragm are snapped together, which facilitates installation and makes it easy to control the tightness of the installation, making the connection between the diaphragm and the valve core more reliable, thereby extending the service life of the diaphragm. Furthermore, the valve core can be used directly without machining threaded holes, which is convenient for processing, saves processing costs, ensures the centering installation of the diaphragm, and reduces the size of the diaphragm valve, making it more compact and reducing the installation space required.

[0004] As shown in the above equipment, the existing diaphragm valve, which is easy to process and install, achieves the snap-fit ​​between the valve core and the diaphragm, making installation convenient and easy to control the tightness of the installation, thus making the connection between the diaphragm and the valve core more reliable. However, if there is no filtration structure, impurities may enter the sealing surface, rub against the sealing surface, accelerate the wear of the sealing surface, shorten the service life of the seal, and lead to frequent replacement of the seal, increasing maintenance costs.

[0027] The sealing connection mechanism 7 is located below the diaphragm valve body 1 to facilitate the connection and installation of the diaphragm valve body 1, and to filter the flowing material with the help of the filter assembly 78.

[0028] The limiting and fixing component 2 is disposed on the outer wall of the diaphragm valve body 1 and is used to limit and fix the diaphragm valve body 1 to prevent the diaphragm valve body 1 from loosening due to external force.

[0029] A limit hole is provided on the outer wall of the diaphragm valve body 1, and a mounting base 3 is fixedly installed at the bottom end of the diaphragm valve body 1. A threaded hole is provided on the outer wall of the mounting base 3.

[0030] Mounting base 3 is threadedly connected to bolt 4 through threaded holes, and mounting base 3 is fixedly connected to diaphragm valve base 5 through bolt 4.

[0031] The diaphragm valve base 5 is fixedly connected to both ends of the connecting pipe 6, and the diaphragm valve base 5 is connected to the sealing connection mechanism 7 through the connecting pipe 6.

[0032] The sealing connection mechanism 7 includes a threaded tube 71, which is located below the diaphragm valve body 1. One end of the threaded tube 71 is fixedly connected to a connecting sleeve 72. The inner wall of the threaded tube 71 is fixedly connected to a limiting cylinder 74. The outer wall of the limiting cylinder 74 is fitted with a return spring A75. One end of the return spring A75 is fixedly connected to a sliding ring 76. The inner wall of the limiting cylinder 74 is provided with a filter assembly 78. The outer wall of the connecting sleeve 72 is slidably connected to a pushing ring 73. The inner wall of the pushing ring 73 is fixedly connected to a movable block. One end of the movable block is fixedly connected to a return spring B77. The inner wall of the connecting sleeve 72 has a limiting groove 79. The limiting groove 79 is movably connected to a limiting valve ball 710.

[0033] The filter assembly 78 includes a limiting ring 784, which is slidably connected to the inner wall of the limiting cylinder 74. A placement ring 781 is fixedly connected to the inner wall of the limiting ring 784. A snap-fit ​​groove 782 is provided on the outer wall of the placement ring 781, and a filter screen 783 is snapped onto the placement ring 781 through the snap-fit ​​groove 782.

[0034] The diaphragm valve, which is easy to process and install, is equipped with a sealing connection mechanism 7. Due to the presence of the sealing connection mechanism 7, the installation process of the diaphragm valve is more standardized and regulated. Installers can install it according to a unified standard and process, which improves the installation efficiency. The filter component can effectively filter impurities and particles in the medium, prevent them from entering the valve, reduce wear and corrosion on the valve sealing surface, diaphragm and other components, extend the service life of the valve, and also protect downstream equipment from the influence of impurities.

[0035] The second embodiment differs from the first embodiment in that: the limiting and fixing assembly 2 includes a connecting ring 21, which is fixedly installed on the outer wall of the diaphragm valve body 1. A sliding groove plate 22 is fixedly installed at the bottom end of the connecting ring 21. A limiting groove plate 23 is fixedly installed at the bottom end of the connecting ring 21. A fixing ring 24 is fixedly installed at the bottom end of the connecting ring 21. The fixing ring 24 is fixedly installed on the outer wall of the diaphragm valve body 1. A movable ring 25 is slidably connected to the outer wall of the sliding groove plate 22. A fixing post 26 is fixedly installed at the bottom end of the movable ring 25.

[0036] This easy-to-process and install diaphragm valve is equipped with a limit fixing component 2. The limit fixing component 2 can position the valve stem, preventing the valve stem from being loosened or tilted due to external forces, thus ensuring the stability of the valve in use.

[0037] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.

[0038] When the entire equipment needs to be installed, the sealing connection mechanism 7 can be installed by threaded rotation using the connecting pipe 6. Then, by pushing the push ring 73, the movable block is moved and the return spring B77 is squeezed. As the push ring 73 gradually moves away from the limit groove 79, the limit valve ball 710 is in an active state. At this time, the return spring A75 resets and drives the sliding ring 76 connected to one end to move. At this time, the pipe can be inserted, with one end of the pipe inserted into the sealing connection mechanism 7. As the pipe gradually enters the sealing connection mechanism 7, it will squeeze the sliding ring 76 and the return spring A75. When it enters to a certain extent and is tightly against the sealing ring 78, the push ring 73 is released. As the return spring B77 moves, it can drive the push ring 710 to move. 3. The reset cover limit groove 79 is also squeezed to move the limit valve ball 710 inward and lock it in the slot opened on the outer wall of the pipe, thus completing the installation. After installation, by pushing the movable ring 25, the fixed column 26 is driven away from the limit hole. When the movable ring 25 is pushed to the outer wall of the connecting ring 21, the fixed column 26 is aligned with the limit groove plate 23 by rotating the movable ring 25. Then the movable ring 25 is slidably connected in the limit groove plate 23. Then the valve handle of the diaphragm valve body 1 can be rotated to open the diaphragm valve body 1 for material transfer. The material enters the limit cylinder 74 through the threaded pipe 71 and is then filtered by the two layers of filter screens 783 in the filter assembly 78, which can filter out the impurities and prevent impurities from entering the valve.
