Description

Technical Field

[0001] This utility model relates to the field of control valve technology, and more specifically, to a flow regulating valve. Background Technology

[0002] Valves are control components in fluid transport systems. Based on their function and purpose, they can be divided into shut-off valves, check valves, regulating valves, and safety valves. Flow regulating valves, also known as flow control valves, are control devices used for intuitive and convenient flow regulation.

[0003] There are many flow control valves on the market. For example, a flow control valve with publication number CN221237185U includes a valve body, a valve core, and a control rod. The valve body has a liquid flow channel, and a control chamber is connected to one side of the liquid flow channel. One end of the control rod passes through the control chamber and is rotatably connected to a sliding sleeve. The control rod can be axially displaced by rotation. The valve core is in the shape of a circular plate or a sheet. The valve core is rotatably connected to the liquid flow channel through a rotating shaft provided on its side. One end of a connecting strip is hinged to the side end of the valve core. The other end of the connecting strip has a limiting part. The sliding sleeve is fitted on the connecting strip and forms a sliding fit.

[0004] This product is easy to operate. It uses a control lever to drive the sliding sleeve to slide, thereby adjusting the position of the valve core to control the water flow. In natural environments, flow regulating valves are needed to control the flow of water. Sand and other impurities in the water will adhere to the surface of the valve core, and the valve core is not convenient to remove and clean at any time. Sand and other impurities between the sliding sleeve and the connecting strip will affect the use of the structure and eventually affect the quality of the valve body. Therefore, we propose a flow regulating valve. Utility Model Content

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the relevant utility model and not intended to limit the scope of the utility model. Furthermore, it should be noted that, for ease of description, only the parts relevant to the utility model are shown in the accompanying drawings.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 A flow regulating valve includes a valve body 1. A valve core 5 is detachably connected to the junction of two liquid flow channels of the valve body 1. A connecting assembly 6 is provided at the bottom of the valve body 1. The connecting assembly 6 includes a receiving block 61 detachably connected to the valve body 1. A rubber sealing ring is fitted on the outer wall of the top of the receiving block 61 above the external thread 611 to prevent water from flowing out from the threaded gap between the receiving block 61 and the bottom of the valve body 1. A limiting block 612 is provided at the center of the bottom surface of the receiving block 61 and is fixedly connected to the bottom surface of the valve core 5. The limiting block 612 and the bottom surface of the receiving block 61 can be fixed by plugging. An annular block 62 is rotatably connected to the outer wall of the bottom end of the receiving block 61. The annular block 62 is fixedly connected to the valve body 1 by bolts. By rotating the receiving block 61, the receiving block 61 and the valve core 5 can be quickly removed as a whole, which is convenient for cleaning the mud or impurities attached to the inside of the receiving block 61 and the side walls of the valve core 5.

[0024] In this embodiment, a connecting cover 2 is fixedly connected to the top of the valve body 1. An internal threaded cylinder 3 is fixedly engaged inside the connecting cover 2. An adjusting assembly 4 is disposed above the connecting cover 2. The adjusting assembly 4 includes a threaded rod 43 threadedly connected to the internal threaded cylinder 3. A limiting plate 44 is disposed at the bottom end of the threaded rod 43. Several baffles 46 for controlling water flow are disposed at the bottom end of the limiting plate 44. The outer walls of the baffles 46 can tightly fit against the inner wall of the valve core 5. The size of the limiting plate 44 is adapted to the inner cavity size of the middle section of the valve body 1. The wall is tightly fitted to the inner surface of the valve body 1, thus ensuring the airtightness of the valve body 1. When the baffles 46 move above the valve core 5, the water flow and the accompanying mud and sand impurities are in motion. The sand and other impurities will adhere to the surface of the filter screen 52 due to the force of the water. When the baffles 46 are fully inserted into the slot 50 of the valve core 5, the water flow is in a static state, and the sand and other impurities will fall into the receiving block 61 due to their own gravity. Through the cooperation of the baffles 46 and the valve core 5, it is easy to control the water flow and the stability is high.

[0025] Furthermore, the adjustment assembly 4 also includes a rotating rod 42 fixedly connected to the threaded rod 43. A knob 41 is provided at the top of the rotating rod 42. The rotating rod 42 is slidably connected to the built-in threaded cylinder 3. A sealing rubber pad is attached to the position where the outer wall of the rotating rod 42 is rotatably connected to the built-in threaded cylinder 3, thereby improving the airtightness of the valve body 1. The position of the baffle plate 46 can be easily adjusted by rotating the threaded rod 43 through the knob 41.

[0026] It should be noted that the top surface of the valve core 5 is provided with several slots 50. The internal dimensions of the slots 50 are adapted to the dimensions of the baffle plate 46. The valve core 5 is hollow inside and has a receiving groove 51 on one side wall. A filter screen plate 52 is fixedly attached in the receiving groove 51. A groove 511 is provided on the side of the valve core 5 near the receiving groove 51. Water flows in from the side near the filter screen plate 52 and flows out from the side away from the filter screen plate 52. The groove 511 facilitates the sliding of impurities such as mud and sand into the receiving block.

[0027] Then, the outer wall of the receiving block 61 is provided with an external thread 611, and the bottom surface of the receiving block 61 is fixedly installed with a rotating handle 63, which facilitates the quick disassembly of the receiving block 61 and the valve core 5.

[0028] Next, sliders 45 are fixedly connected to both sides of the limiting plate 44, and grooves 11 are opened on both side walls of the valve body 1 near the top. The sliders 45 are slidably connected in the grooves 11 to facilitate normal use of the structure.

[0029] In this embodiment, the valve body 1 is provided with a first threaded groove 12 and a second threaded groove 13 from top to bottom inside. The top of the valve core 5 is threadedly connected to the first threaded groove 12. Flange rings 7 are installed on the outer sidewalls of the two liquid flow channels of the valve body 1. The external thread 611 on the outer wall of the receiving block 61 is threadedly connected to the second threaded groove 13, thereby facilitating the use of the valve core 5 and the receiving block 61.

[0030] It should be added that the bottom surface of the valve body 1 is provided with several reserved holes 14, which are used for bolt fixing operations, thereby facilitating the use of the structure.

[0031] Working principle: When using this flow regulating valve, the user first connects the receiving block 61 and the valve core 5, which is fixedly connected by the limiting block 612, to the inside of the valve body 1 via the handle 63. Then, the user rotates the knob 41, which drives the threaded rod 43, which is fixedly connected to the rotating rod 42, to rotate, thereby adjusting the position of the baffle plate 46. This facilitates the cooperation between the baffle plate 46 and the valve core 5 to regulate the water flow. After use, the user reverses the rotation to remove the receiving block 61 and the valve core 5, and cleans the internal sediment and dirt.

[0032] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the utility model involved in this application is not limited to the technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
