Description

Technical Field

[0001] This utility model relates to the field of heat exchanger control technology, specifically a water level control device for a heat exchanger at the first station of a heating network. Background Technology

[0002] The heating station in a centralized heating system is the connection point between the heating network and heat users. Its function is to regulate and convert the heat medium supplied by the heating network according to different connection methods based on the operating conditions of the heating network, distribute heat to the user systems to meet user needs, and, as needed, centrally meter and monitor the parameters and quantity of the heating medium. The water level in the heat exchanger is a crucial control indicator in the initial stage of the heating network operation. During operation, the heat exchanger should maintain a certain water level. If the water level is too high, it will reduce the steam heat exchange area, affecting heat exchange efficiency and the safety of the unit's steam extraction for heating. If the water level is too low, it will cause excessively high condensate temperature, resulting in poor thermal efficiency and potential erosion damage to the tube bundles.

[0003] Chinese patent publication number CN220103847U discloses a heat exchanger control device, filed on June 26, 2023. This patented technology uses a hoisting device connected to two lifting rings on the heat exchanger, lifting the heat exchanger body and placing it into two limiting seats. This ensures the lower part of the heat exchanger body fits tightly against the support pads. A screw is then rotated via a handle, and the screw, through a movable sleeve, clamps and limits the heat exchanger body, ensuring a tight fit between the inner wall of the clamping block and the outer surface of the heat exchanger body. This facilitates installation and subsequent disassembly and maintenance. However, the above device requires rotating bolts on both sides to clamp and fix the heat exchanger, which requires many rotations, including turning four bolts, resulting in excessively long fixing times and inconvenience. Therefore, the inventor provides a water level control device for the heat exchanger at the first station of a heating network to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this utility model is to provide a water level control device for the heat exchanger at the first station of a heating network, so as to achieve the effect of convenient fixed support for the heat exchanger.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A water level control device for a heat exchanger at the first station of a heating network includes a heat exchanger body. An inlet pipe is fixedly connected to the right side of the heat exchanger body, and a drain pipe is fixedly connected to the left side of the heat exchanger body. A water level detection sensor is installed on the top side inside the heat exchanger body. A support and fixing mechanism is installed at the bottom of the heat exchanger body. The support and fixing mechanism includes a support base. Support columns are fixedly connected to the top left and right sides of the support base, respectively. A support block is fixedly connected to the top of each support column. A tilting groove is formed on the rear side of the top of the support block. A tilting groove has a rotatable arc-shaped block rotatably connected to it via a movable shaft. A pair of positioning rings are fixedly connected to the left and right sides of the surface of the heat exchanger body, respectively.

[0007] As a further embodiment of this utility model: an insert block is fixedly connected to the top right side of the arc-shaped block, a sliding groove is provided on the right side of the insert block, a positioning block is slidably connected inside the sliding groove, a support spring is fixedly connected to the left side of the positioning block, and the left side of the support spring is fixedly connected to the sliding groove; a slot is provided on the top left side of the support block, and a positioning groove is provided on the left side inside the slot.

[0008] As a further improvement of this utility model, the right side surface of the positioning block has an arc-shaped design that gradually lengthens from top to bottom.

[0009] As a further improvement of this utility model, a return spring is fixedly connected to the bottom side of the slot.

[0010] As a further embodiment of this utility model: a connecting frame is fixedly connected to the left side of the support block, and a pressing block is rotatably connected inside the connecting frame via a movable shaft. A stop block is fixedly connected to the right side of the pressing block. Fixed rings are fixedly connected to the front and rear sides of the inside of the connecting frame, and a spiral spring is provided inside the fixed ring. The outer end of the spiral spring is fixedly connected to the fixed ring, and the inner end of the spiral spring is fixedly connected to the movable shaft.

[0011] As a further embodiment of this utility model: a first water distributor is fixedly connected to the left side of the drain pipe, and a pair of mirror-symmetrical diversion pipes are fixedly connected to the left end of the first water distributor. The left sides of the two diversion pipes are fixedly connected to a merging pipe through a second water distributor; a guide pipe is fixedly connected to the right side of the heat exchanger body, and a first manual valve is installed on the guide pipe.

[0012] As a further embodiment of this utility model: a first valve is installed on the water inlet pipe; a second valve is installed on the front branch pipe, and a first manual valve is installed on the rear branch pipe; a controller is provided on the outside of the heat exchanger body, and the controller is electrically connected to the first valve, the second valve and the water level detection sensor respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The water level control device for the heat exchanger at the first station of this heating network achieves initial positioning by placing the heat exchanger body on the surfaces of two support blocks and inserting a pair of fixing rings on the same side of the support blocks. Then, the arc-shaped blocks on both sides are flipped forward, merging with the support blocks and fully inserting the inserts into the slots. During this process, the positioning block contacts the slot surface, and the contact force causes the positioning block to slide into the sliding groove and compresses the support spring. When the positioning block aligns with the positioning groove, the support spring rebounds, causing the positioning block to move outward and insert into the positioning groove, thus fixing the positioning block. The positioning block and support blocks then merge to complete the fixing and support of the heat exchanger body. This device facilitates convenient fixing and support of the heat exchanger.

[0015] In addition, the water level control device for the heat exchanger at the first station of this heating network uses an external power source to activate a water level sensor. This sensor detects the liquid level inside the heat exchanger and feeds the information back to the controller. Operators input a set liquid level, and the controller compares this input level with the current water level depth inside the heat exchanger. If the water level is insufficient, the controller activates the first valve via external power, allowing water to enter the heat exchanger through the inlet pipe. Simultaneously, the water level sensor provides real-time feedback on the water level depth inside the heat exchanger. The controller closes the first valve when the water level inside the heat exchanger matches the water level input by the operator. When the water level inside the heat exchanger exceeds the set value input by the operator, the controller opens the second valve via an external power supply. This allows water inside the heat exchanger to be discharged sequentially through the drain pipe, the front branch pipe, and the merging pipe. Simultaneously, the water level sensor provides real-time feedback on the water level inside the heat exchanger. The controller closes the second valve when the water level inside the heat exchanger matches the set value input by the operator, thus achieving the effect of controlling the water level inside the heat exchanger.

[0022] like Figure 1 , 2 As shown, a water level control device for a heat exchanger at the first station of a heating network includes a heat exchanger body 10. A water inlet pipe 11 is fixedly connected to the right side of the heat exchanger body 10, and a drain pipe 13 is fixedly connected to the left side of the heat exchanger body 10. A water level detection sensor 14 is installed on the top side inside the heat exchanger body 10.

[0023] refer to Figure 1 , 2 The left side of the drain pipe 13 is fixedly connected to a first water distributor 20, and the left connecting end of the first water distributor 20 is fixedly connected to a pair of mirror-symmetrical diversion pipes 21. The left sides of the two diversion pipes 21 are fixedly connected to a merging pipe 25 through a second water distributor 22.

[0024] Preferably, a first valve 12 is installed on the inlet pipe 11; a second valve 24 is installed on the front branch pipe 21, and a second manual valve 23 is installed on the rear branch pipe 21; a controller 15 is provided on the outside of the heat exchanger body 10, and the controller 15 is electrically connected to the first valve 12, the second valve 24, and the water level detection sensor 14. In use, the water level detection sensor 14 is activated by an external power supply. The water level detection sensor 14 detects the liquid level inside the heat exchanger body 10 and then feeds the detected information back to the controller 15. The operator inputs the set liquid level height, and the controller 15 compares the input water level height with the current water level depth of the heat exchanger body 10. If the current water level depth of the heat exchanger body 10 is insufficient, the controller 15 will activate the first valve 12 by an external power supply, allowing water to enter the interior of the heat exchanger body 10 through the inlet pipe 11. Simultaneously, the water level detection sensor 14 provides real-time feedback on the water level depth of the heat exchanger body 10 until the water reaches the interior of the heat exchanger. When the water level inside the heat exchanger body 10 matches the water level input by the operator, the controller 15 closes the first valve 12. When the water level inside the heat exchanger body 10 exceeds the set value input by the operator, the controller 15 opens the second valve 24 via an external power supply. As a result, the water inside the heat exchanger body 10 is discharged sequentially through the drain pipe 13, the front branch pipe 21, and the merging pipe 25. At the same time, the water level detection sensor 14 provides real-time feedback on the water level depth inside the heat exchanger body 10 until the water level inside the heat exchanger body 10 matches the set value input by the operator. Then, the controller 15 closes the second valve 24, thereby achieving the effect of controlling the water level inside the heat exchanger body 10.

[0025] Preferably, a guide pipe 16 is fixedly connected to the right side of the heat exchanger body 10, and a first manual valve 17 is installed on the guide pipe 16. When the device is powered off, in order to adjust the water level inside the heat exchanger body 10, water can be injected into the heat exchanger through the guide pipe 16 by opening the first manual valve 17, or the second manual valve 23 can be opened, so that the water inside the heat exchanger body 10 can be discharged through the drain pipe 13, the rear branch pipe 21, and the merging pipe 25, thereby achieving the effect of manually controlling the water level inside the heat exchanger body 10.

[0026] refer to Figure 1 , 2 The heat exchanger body 10 is equipped with a support and fixing mechanism 30 at its bottom. The support and fixing mechanism 30 includes a support base 301. Support columns 302 are fixedly connected to the top left and right sides of the support base 301, and a support block 303 is fixedly connected to the top of the support column 302. A flip groove 304 is opened on the rear side of the top of the support block 303. A fliptable arc-shaped block 305 is rotatably connected inside the flip groove 304 through a movable shaft. A pair of positioning rings 40 are fixedly connected to the left and right sides of the surface of the heat exchanger body 10, respectively.

[0027] In use, the heat exchanger body 10 is placed on the surfaces of the two support blocks 303, and a pair of positioning rings 40 on the same side are inserted into the surfaces of the support blocks 303 to achieve the effect of initial positioning.

[0028] For details, please refer to Figure 3 , 4 5. An insert block 307 is fixedly connected to the top right side of the arc-shaped block 305. A sliding groove 308 is provided on the right side of the insert block 307. A positioning block 309 is slidably connected inside the sliding groove 308. A support spring 310 is fixedly connected to the left side of the positioning block 309. The left side of the support spring 310 is fixedly connected to the sliding groove 308. A slot 306 is provided on the top left side of the support block 303. A positioning groove 311 is provided on the left side inside the slot 306.

[0029] Preferably, the right side surface of the positioning block 309 has an arc-shaped design that gradually lengthens from top to bottom. After initial positioning, the arc-shaped blocks 305 on both sides are flipped forward, so that the arc-shaped blocks 305 and the support block 303 merge, and the insert block 307 is fully inserted into the slot 306. During this process, the positioning block 309 will contact the surface of the slot 306. The contact force causes the positioning block 309 to slide into the sliding groove 308 and compresses the support spring 310 until the positioning block 309 corresponds to the positioning groove 311. Then, the support spring 310 rebounds and drives the positioning block 309 to move outward and insert into the positioning groove 311, thereby achieving the effect of fixing the positioning block 309. The positioning block 309 and the support block 303 merge to complete the fixing and support of the heat exchanger body 10.

[0030] Preferably, a return spring 312 is fixedly connected to the bottom inner side of the slot 306. When the insert 307 is fully inserted into the slot 306, the bottom of the insert 307 abuts against the return spring 312, compressing the return spring 312. Thus, when it is necessary to open the arc block 305, pressing the positioning block 309 disengages the positioning block 309 from the positioning groove 311, thereby causing the deformation force of the return spring 312 to spring up the insert 307 and the arc block 305, thus facilitating the opening of the arc block 305.

[0031] Furthermore, a connecting frame 313 is fixedly connected to the left side of the support block 303. A pressing block 314 is rotatably connected inside the connecting frame 313 via a movable shaft. A stop block 315 is fixedly connected to the right side of the pressing block 314. Fixing rings 316 are fixedly connected to the front and rear sides of the inside of the connecting frame 313, respectively. A spiral spring 317 is installed inside the fixing ring 316. The outer end of the spiral spring 317 is fixedly connected to the fixing ring 316, and the inner end of the spiral spring 317 is fixedly connected to the movable shaft. When not in use, the spiral spring 317 supports the pressing block 314, maintaining a certain distance between the pressing block 314 and the surface of the support block 303. When in use, press the pressing block 314, causing the pressing block 314 to drive the abutment block 315 to flip to the right and contact the positioning block 309 until the positioning block 309 is pushed out of the positioning groove 311, thereby achieving the effect of facilitating the fixation of the heat exchanger body 10, and thus facilitating the maintenance or replacement of the heat exchanger body 10.

[0032] The working principle of this utility model is as follows: The heat exchanger body 10 is placed on the surface of two support blocks 303, and a pair of positioning rings 40 on the same side are inserted into the surface of the support blocks 303 to achieve a preliminary positioning effect. Then, the arc-shaped blocks 305 on both sides are flipped forward so that the arc-shaped blocks 305 and the support blocks 303 merge, and the insert blocks 307 are fully inserted into the interior of the slots 306. During this process, the positioning blocks 309 will contact the surface of the slots 306. The contact force causes the positioning blocks 309 to slide into the sliding grooves 308 and compresses the support springs 310 until the positioning blocks 309 correspond to the positioning grooves 311. Then, the support springs 310 rebound and drive the positioning blocks 309 to move outward and insert into the interior of the positioning grooves 311, thereby achieving the effect of fixing the positioning blocks 309. The positioning blocks 309 and the support blocks 303 merge to complete the fixing and support of the heat exchanger body 10.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
