Description

Technical Field

[0001] The utility model relates to a valve, in particular to a valve with an anti-blocking connector, belonging to the technical field of valves. Background Art

[0002] Valves are control components in pipeline fluid delivery systems. They are used to change the cross-section of the passage and the direction of medium flow. They have functions such as diversion, cutoff, regulation, and throttling. Valves can act according to predetermined requirements under the action of pressure, temperature or other forms of sensor signals, or simply open or close without relying on sensor signals. When sewage flows through the valve, impurities in it are easy to clog the valve, causing the valve to fail to operate normally.

[0003] An anti-clogging valve structure is disclosed in the Chinese patent disclosure specification CN212651436U. Before the sewage enters the valve, the sewage passes through the filtering structure in the water inlet pipe. The sewage flows through the first filter cartridge and the second filter cartridge in the filtering structure. The first filter cartridge and the second filter cartridge are both made of mesh plates welded together, and the mesh of the first filter cartridge is larger than the mesh of the second filter cartridge, so that it is convenient to classify and filter impurities of different volumes, thereby purifying large particle impurities in the sewage.

[0004] Although the above anti-blocking valve structure can filter impurities of different volumes by setting filter screens with different mesh diameters, it is found in actual applications that impurities filtered through the filter screen will accumulate on one side of the filter screen. As impurities accumulate on the filter screen, the flow channel of the sewage will become narrow, resulting in a reduction in flow. For this reason, we provide a valve with an anti-blocking connector. Utility Model Content

[0005] The utility model provides a valve with an anti-blocking connector, which can clean up impurities in time to prevent the impurities from accumulating on a filter net and prevent impurities of a smaller volume from entering the valve during the cleaning process.

[0006] The utility model is implemented through the following technical scheme: it includes a valve, both ends of the valve are provided with a filtering and cleaning mechanism, the filtering and cleaning mechanism includes a shell, a sealing door is installed on the side of the shell, both sides of the shell are provided with water-permeable holes connected to the valve, a filter plate is fixed inside the shell, the upper and lower sides of the shell are rotatably connected with threaded rods through bearings, the side of the threaded rod is threadedly connected with a threaded block, the upper and lower sides of the shell are provided with through holes, the threaded block is fixedly connected to a side of the shell close to two sliding rods penetrating the through holes, the other end of the sliding rod is fixed with a sealing ball, and the other end of the sealing ball is fixed with a sealing plate in contact with the inner wall of the shell.

[0007] Specifically, a first sealing gasket located at the position of the through hole is fixed to the inner wall of the shell, and a fixing flange is fixed to one side of the shell. The provision of the first sealing gasket can improve the sealing effect between the sealing ball and the through hole.

[0008] Specifically, a knob is fixed to one end of the threaded rod away from the housing, and anti-slip grooves are provided on the side of the knob. The knob is provided to facilitate the rotation of the threaded rod, which is convenient to use.

[0009] Furthermore, the diameter of the sealing ball is larger than the inner diameter of the through hole, so that the through hole can be sealed by the sealing ball.

[0010] Specifically, the length of the sealing plate is greater than the diameter of the water permeable hole, and the width of the sealing plate is greater than the radius of the first sealing gasket, so that the sealing plate can seal the water permeable hole.

[0011] Furthermore, a fixing block is fixed to the inner wall of the shell, a guide rod is fixed on the fixing block, and a slider slidably connected to the guide rod is fixed to the side of the sealing plate. The sealing plate can be guided by the cooperation of the fixing block, the guide rod and the slider.

[0012] Specifically, a compression spring sleeved on the side of the guide rod is fixed between the sliding block and the fixed block, and a second sealing gasket is fixed on the sealing plate. The provision of the second sealing gasket can improve the sealing effect between the two sealing plates.

[0013] The utility model provides a valve with an anti-blocking connector, which has the following beneficial effects:

[0014] The valve with an anti-blocking connector can effectively filter impurities in sewage by providing a filter plate to prevent the impurities from clogging the valve. The threaded block and the slide rod can be moved toward the shell by rotating the threaded rod, and the sealing plate is then driven to move by the sealing ball. The water permeable hole is sealed by two sealing plates close to each other. At this time, the inside of the shell and the filter plate can be flushed by opening the sealing door, and at the same time, smaller impurities can be prevented from entering the valve during the impurity cleaning process.

[0027] Please refer to Figure 2 , Figure 3 , Figure 4 , Figure 3 and Figure 6A filter plate 202 is fixed inside the shell 201, and the filter plate 202 can be used to filter impurities in the sewage. Preferably, a plurality of filter plates 202 can be provided, and the inner diameters of the filter holes are different, so that impurities of different volumes can be filtered. The upper and lower sides of the shell 201 are rotatably connected with a threaded rod 203 through a bearing. A knob 2031 is fixed to the end of the threaded rod 203 away from the shell 201. The side of the knob 2031 is provided with anti-slip grooves. The knob 2031 is provided to facilitate the rotation of the threaded rod 203, which is more convenient to use. The side of the threaded rod 203 is threadedly connected with a threaded block 204. Through holes 205 are provided on the upper and lower sides of the shell 201. The threaded block 204 is close to the shell One side of the body 201 is fixedly connected to two sliding rods 206 that pass through the through holes 205, and the other end of the sliding rod 206 is fixed with a sealing ball 207, the diameter of the sealing ball 207 is larger than the inner diameter of the through hole 205, so that the through hole 205 can be sealed by the sealing ball 207, and the cooperation of the sealing ball 207, the through hole 205 and the knob 2031 can avoid water leakage in the through hole 205, and the other end of the sealing ball 207 is fixed with a sealing plate 208 that contacts the inner wall of the shell 201, the length of the sealing plate 208 is larger than the diameter of the water permeable hole 2012, and the width of the sealing plate 208 is larger than the radius of the first sealing gasket 2013, so that the sealing plate 208 can seal the water permeable hole 2012.

[0028] Specifically, when the threaded rod 203 is rotated by the knob 2031, since the threaded block 204 is limited by the sliding rod 206, the sealing ball 207 and the sealing plate 208, the rotating threaded rod 203 will cause the threaded block 204 to move along the axial direction of the threaded rod 203, and the threaded block 204 will drive the sliding rod 206, the sealing ball 207 and the sealing plate 208 to move. The water permeable hole 2012 can be sealed by the two sealing plates 208 moving towards each other, so that the interior of the shell 201 is in a sealed state, and the shell 201 is no longer connected to the fixed flange 3 and the valve 1. At this time, the sealing door 2011 is opened to rinse the inner wall of the shell 201 and the impurities attached to the filter plate 202.

[0029] Please refer to Figure 7A fixing block 2081 is fixed to the inner wall of the shell 201, and a guide rod 2082 is fixed on the fixing block 2081.

A compression spring 2084 is fixed between the slider 2083 and the fixing block 2081 and is sleeved on the side of the guide rod 2082. The elastic force generated by the deformation of the compression spring 2084 can provide a certain preload force. The sealing plate 208 moves more stably on the guide rod 2082 through the slider 2083. A second sealing gasket 2085 is fixed on the sealing plate 208. The provision of the second sealing gasket 2085 can improve the sealing effect between the two sealing plates 208 and prevent water from flowing out from between the two sealing plates 208.

[0030] Working principle: First, the device is installed through the fixed flange 3, and the filter plate 202 can be used to effectively filter impurities in the sewage to prevent the impurities from clogging the valve 1. The threaded block 204 and the slide bar 206 can be moved toward the housing 201 by rotating the threaded rod 203. During this process, the slide bar 206 will also drive the sealing plate 208 to move through the sealing ball 207. The two sealing plates 208 close to each other can seal the water permeable hole 2012. Then open the sealing door 2011 to flush the inside of the housing 201 and the filter plate 202.
