Description

Technical Field

[0001] The utility model relates to the field of regulating valves, in particular to a high-performance eccentric rotary regulating valve. Background Art

[0002] In modern industrial production and fluid delivery systems, regulating valves play a vital role. Among them, eccentric rotary regulating valves are widely used because of their advantages such as wide adjustment range, good sealing performance and strong stability. However, traditional eccentric rotary regulating valves have some obvious shortcomings in practical applications.

[0003] On the one hand, whether it is water, oil or other types of fluids, they will inevitably carry some impurities during transmission. Impurities in water and other fluids are easy to accumulate in the gaps of the internal parts of the regulating valve. When the regulating valve needs to be closed, these accumulated impurities will hinder the close fit between the valve core and the valve seat. If the accumulated impurities reach a certain amount, it is easy to cause the regulating valve to fail to close completely, thereby greatly reducing the flow blocking effect and affecting the normal use of the device.

[0004] Traditional eccentric rotary control valves, on the other hand, are typically installed on pipes via flanges. During installation, workers must hold the flange in place, align it with the threaded holes, and then tighten the bolts to secure it. However, due to the flange's weight and bulk, it tends to wobble when held, making it difficult to accurately align the threaded holes on the flange with those on the pipe. This not only increases installation difficulty but also prolongs installation time. Summary of the Invention

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The valve body 1, the water outlet pipe 2 and the water inlet pipe 3 together constitute an eccentric rotary regulating valve, which is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. A filter component is provided inside the water inlet pipe 3, which can block and filter impurities in the fluid to prevent impurities from accumulating in the valve body 1 and affecting the normal use of the device. A quick-install component is provided on the right surface of the water inlet pipe 3 to facilitate the installation of the device on the pipeline.

[0033] Reference Figure 1 、 Figure 3 The filter assembly includes a filter plate 45, a through groove 1 401 is provided on the lower surface of the water inlet pipe 3, and the outer wall of the water inlet pipe 3 is rotatably connected to the ring sleeve 41. The inner wall of the ring sleeve 41 is made of rubber and fits tightly against the outer wall of the water inlet pipe 3 to maintain a seal. A through groove 2 402 is provided on the lower surface of the ring sleeve 41, and the through groove 1 401 and the through groove 2 402 fit together. A card slot 403 is provided on the front surface of the water inlet pipe 3. The filter assembly also includes a pull rod 44, and the inner wall of the ring sleeve 41 is elastically connected to the card block 42 through a compression spring 43. The rear surface of the pull rod 44 is fixedly connected to the front surface of the card block 42. Pulling the pull rod 44 can drive the card block 42 to move.

[0034] Reference Figure 1 - Figure 2 The quick-install component includes a flange 51, which is provided with a threaded hole and can be connected to the pipeline. The outer wall of the flange 51 is fixedly connected to a positioning ring 52. When the flange 51 and the pipeline are connected, the positioning ring 52 will wrap the flange 51 on the pipeline. The inner wall of the positioning ring 52 is elastically connected to a stopper 54 through a connecting spring 53. The stopper 54 can block the flange 51 on the pipeline.

[0035] Reference Figure 1 、 Figure 3, the filter plate 45 is fixedly connected to the middle section of the inner wall of the water inlet pipe 3, and the right surface of the filter plate 45 is provided with filter holes, water and other fluids can pass through the filter holes, and impurities will be blocked. The filter plate 45 is located on the left side of the through groove 1 401, and the through groove 1 401 has a certain depth. The impurities blocked by the filter plate 45 will fall into the through groove 1 401, and the through groove 1 401 and the through groove 2 402 are the same size. When the through groove 1 401 and the through groove 2 402 coincide with each other, the impurities can be discharged from the water inlet pipe 3, and the pull rod 44 passes through and is slidably connected to the front surface of the ring sleeve 41. The front surface of the pull rod 44 is fixedly connected with a pull ring for easy pulling. The block 42 is inserted into the inner wall of the card slot 403, and the back of the block 42 The top and bottom ends of the surface are chamfered to facilitate insertion into the card slot 403. There are two groups of card slots 403, and the two groups of card slots 403 are symmetrically distributed front to back with the center line of the ring sleeve 41. When the block 42 is inserted into the card slot 403 at the front position, the through slot 1 401 and the through slot 2 402 will overlap. The block 42 passes through and is slidably connected to the rear surface of the ring sleeve 41. One end of the compression spring 43 is fixedly connected to the front surface of the block 42, and the other end of the compression spring 43 is fixedly connected to the inner wall of the front side of the ring sleeve 41. When the block 42 moves forward, it will retract into the ring sleeve 41, disengage from the card slot 403 to release the limit, and squeeze the compression spring 43 to generate a reaction force.

[0036] Reference Figure 1 - Figure 2 The flange 51 is fixedly connected to the right surface of the water inlet pipe 3, one end of the connecting spring 53 is fixedly connected to the front surface of the stopper 54, and the other end of the connecting spring 53 is fixedly connected to the inner wall of the front side of the flange 51. The stopper 54 passes through and is slidably connected to the rear surface of the flange 51. When the stopper 54 moves forward, it will squeeze the connecting spring 53 to generate a reaction force. The stopper 54 is located on the right side of the flange 51. The flange 51 is provided with two groups, which are evenly distributed on the left surface of the water outlet pipe 2 and the right surface of the water inlet pipe 3. The rear surface of the stopper 54 is set to an arc surface. When the arc surface of the stopper 54 is squeezed, the stopper 54 will move forward. When the left and right surfaces of the stopper 54 are squeezed to the rear position, the arc surface will be squeezed.

[0037] Working principle: When using this device, you need to install the device on the pipeline first. During installation, first align the flange 51 on the water inlet pipe 3 with the flange 51 on the pipeline and use the positioning ring 52 to wrap the flange 51 on the pipeline. During the movement, the flange 51 on the pipeline will squeeze the arc surface of the block 54, so that the block 54 moves and retracts into the positioning ring 52 to release the blockage. The moving block 54 will squeeze the connecting spring 53 to generate a reaction force. When the flange 51 on the water inlet pipe 3 and the flange 51 on the pipeline are close to each other, the squeezing of the block 54 will be released, and the reaction force of the connecting spring 53 will push the block 54 to move backward, blocking the flange 51 on the pipeline, which can support the device and facilitate the staff to use bolts to install the device.

[0038] After the device is installed, it can be put into use. During use, the fluid will enter the water inlet pipe 3 through the pipeline. The impurities in the fluid will be blocked when passing through the filter plate 45, playing a filtering role. When the fluid stops, the impurities will sink into the through groove 1 401 under the influence of gravity. If it is necessary to clean the impurities in the through groove 1 401, the pull rod 44 can be pulled to drive the clamping block 42 to retract into the ring sleeve 41. The clamping block 42 will squeeze the compression spring 43 to generate a reaction force, and will disengage from the clamping groove 403 to release the limit. After the limit is released, the ring sleeve 41 is rotated 180 degrees. At this time, the block 42 will be aligned with the other slot 403. Under the push of the compression spring 43, the block 42 will be inserted into the slot 403 to limit the ring sleeve 41. At this time, the through groove 1 401 and the through groove 2 402 will also be aligned, and the accumulated impurities will be discharged from the through groove 2 402 to the water inlet pipe 3. Similarly, when the device is used, the limit of the ring sleeve 41 can be released, and then the ring sleeve 41 can be rotated 180 degrees again to keep the through groove 1 401 and the through groove 2 402 away from each other to prevent leakage.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
