Description

Technical Field

[0001] This utility model belongs to the field of heating regulation technology, and in particular relates to a regulating device for hydraulic balance of heating networks. Background Technology

[0002] Heating networks use hot water to provide heat to the pipes. When the temperature of the heating pipes needs to be adjusted, hydraulic balance is often used to regulate the flow rate of the hot water.

[0003] However, the existing hydraulic balance regulating device has a relatively sophisticated structure and high production cost. In addition, the water supply in the heating network usually contains impurities such as scale, which can easily cause blockage at the inlet after long-term use. This makes it difficult to clean later and can affect the water intake efficiency of the drainage pipe. Utility Model Content

[0004] The purpose of this invention is to provide a regulating device for hydraulic balancing of heating networks, thereby solving the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an adjusting device for hydraulic balancing in a heating network, comprising a connecting pipe body. A connecting seat is fixedly connected to the upper surface of the rear end of the connecting pipe body. A mating sleeve, which is annular, is fixedly connected to the interior of the rear end of the connecting pipe body. The mating sleeve is fixedly connected to the inner wall of the connecting pipe body. A linkage rod is rotatably connected to one side of the interior of the connecting seat. One end of the linkage rod is located inside the mating sleeve and rotatably engages with it. An adjusting plate is fixedly connected to the periphery of the linkage rod. The adjusting plate is located inside the connecting pipe body and rotatably engages with it. The adjusting plate is circular and fits the mating sleeve. Multiple sets of through holes are formed on the surface of the adjusting plate. A limiting gear is fixedly connected to the other end of the linkage rod. The limiting gear is located above the connecting seat. An arc-shaped groove is formed on the upper surface of the front end of the connecting pipe body. Both sides of the inner wall of the front end of the connecting pipe body are provided with mating slide rails, which are located at the arc-shaped groove.

[0007] The arc-shaped groove is fitted with a cover plate, and a filter plate is fixedly connected to the bottom surface of the cover plate. The filter plate is disposed in the connecting pipe body, and the bottom end of the filter plate is attached to the inner wall of the connecting pipe body. The two ends of the filter plate are respectively disposed in two sets of matching slide rails and slide in cooperation with the matching slide rails.

[0008] A limiting rod is fixedly connected inside the connecting seat. The limiting rod is located on one side of the limiting gear plate. A limiting protrusion is slidably connected to the periphery of the limiting rod. One end of the limiting protrusion is engaged with the limiting gear plate, and the other end is fixedly connected to a pressure plate. A cooperating spring is installed between the bottom surface of the limiting protrusion and the connecting seat. The cooperating spring is located on the periphery of the limiting rod.

[0009] A water pressure monitoring meter is installed on the other side of the connector. The water pressure monitoring meter is located on one side of the limiting rod, and the monitoring end of the water pressure monitoring meter is located inside the connecting pipe. By installing the water pressure monitoring meter, the water flow rate inside the connecting pipe can be monitored.

[0010] The inner part of the mating cover plate is provided with a fastening screw, one end of which is threadedly connected to the connecting pipe body, and a rotating head is fixedly connected to the upper surface of the limiting gear plate.

[0011] Sealing sleeves are provided at the connection points between the linkage rod and the connecting pipe body, as well as at the connection points between the mating cover plate and the arc groove. By providing sealing sleeves, the sealing performance at the connection points between the linkage rod and the connecting pipe body, as well as at the connection points between the mating cover plate and the arc groove, is improved, thus preventing water leakage.

[0012] This utility model has the following beneficial effects:

[0013] This utility model, through the setting of a linkage rod, a limiting gear plate, a limiting rod, and an adjusting plate, presses down the pressure plate, causing it to drive the limiting protrusion to squeeze the cooperating spring. The cooperating spring deforms, causing the limiting protrusion to disengage from the limiting gear plate, thereby allowing the linkage rod to rotate, which in turn causes the adjusting plate to rotate within the connecting pipe body, adjusting the angle between the adjusting plate and the cooperating sleeve, thus adjusting the gap between the adjusting plate and the cooperating sleeve. Subsequently, the limiting protrusion is released, and under the action of the cooperating spring, the limiting protrusion re-engages with the limiting gear plate, fixing the position of the adjusting plate, thereby regulating the flow rate of hot water. The structure is simple, easy to operate, and has low production costs. By setting a cooperating cover plate, a cooperating slide rail, and a filter plate, the filter plate is inserted into the connecting pipe body along the cooperating slide rail, and the cooperating cover plate is fixed to the connecting pipe body with fastening screws. The filter plate filters the water supply, avoiding subsequent interference.

[0027] The inside of the arc-shaped groove is fitted with a cover plate 102. A filter plate 116 is fixedly connected to the bottom surface of the cover plate 102. The filter plate 116 is set inside the connecting pipe body 1. The bottom end of the filter plate 116 is in contact with the inner wall of the connecting pipe body 1.

A cooperating spring 111 is installed between the bottom surface of the limiting protrusion 109 and the connecting seat 101. The cooperating spring 111 is located on the periphery of the limiting rod 108.

[0029] A water pressure monitoring meter 103 is installed on the other side inside the connector 101. The water pressure monitoring meter 103 is located on one side of the limit rod 108, and the monitoring end of the water pressure monitoring meter 103 is located inside the connecting pipe 1.
