[0030] See also Figure 1 and Figure 2 , a corner reinforcement sleeve 6 is provided on the right side fixed sleeve of the surface of the transmission pipeline 1, and the four corners of the bottom of the liquid storage tank 3 are fixedly connected with a reinforcement frame 4, and the bottom of the reinforcement frame 4 is fixedly connected to the top of the transmission pipeline 1;

[0031] The transmission tube 706 and the connection head 707 are fixedly installed by fasteners, and the fasteners include bolts and nuts. The bolts pass through the transmission tube 706 and the connection head 707 from top to bottom and are threadedly connected with the nuts. The nuts are located at the bottom of the connection head 707.

[0032] The bottom of the transmission screw 702 is smooth, and the smooth surface of the transmission screw 702 is movably connected to the guide block 704 through a cylindrical roller bearing;

[0033] The connection between the transmission screw 702 and the fixed screw sleeve 703 is sealed to prevent the leakage medium from escaping, and the shape of the sealing seat 708 is a truncated cone;

[0034] By setting the drainage inclined plate 201, it can play the role of drainage and transmission, and can guide the medium outward under the assistance of gravity. By setting the water pump 202 and the suction pipe 203, when the water pump 202 is in working state, the suction pipe 203 can suck the excess medium in the liquid storage tank 3 and discharge it;

[0035] By providing a liquid storage tank 3, the temporary storage demand of the transmission medium can be met. By providing a reinforcement frame 4, the transmission pipeline 1 and the liquid storage tank 3 can be fixedly connected, thereby ensuring the installation stability of the liquid storage tank 3. By providing a liquid level sensor 5, the liquid level height of the storage medium in the liquid storage tank 3 can be detected in real time.

[0036] By providing a corner reinforcement sleeve 6, it can be installed at the corner of the transmission pipeline 1 to improve the overall stability of the device. By providing a driving hand wheel 701, it is convenient for the staff to drive the transmission screw 702 to rotate;

[0037] By providing the transmission screw 702 and the fixed screw sleeve 703, the function of thread transmission can be achieved, and since the fixed screw sleeve 703 is in a fixed state, when the transmission screw 702 is rotated, the transmission screw 702 is synchronously displaced up and down;

[0038] By providing the guide block 704 and the fixing frame 711, a positioning and guiding function can be achieved, and the guide block 704 can be stably displaced up and down. By providing the connecting spring 705, the sealing seat 708 can be elastically supported, and the force to be overcome by the sealing seat 708 to move upward can be increased.

[0039] By providing the transmission tube 706 and the connector 707, the space requirement for the medium to move upward can be met in the installed state. By providing the sealing seat 708, it can slide and seal with the inner wall of the transmission tube 706, so as to prevent the medium from moving upward and flowing out of the transmission tube 706 at will in the natural state. By providing the displacement rod 709 and the positioning sleeve 710, it can play an auxiliary guiding role, and can greatly improve the stability of the sealing seat 708 moving up and down.

[0040] In actual application, the liquid outlet of the water pump 202 is connected to an external container through a pipeline to discharge the pressure relief medium in the liquid storage tank 3;

[0041] In actual application, a protection box is installed outside the reflux extraction mechanism 2 and the driving hand wheel 701. When the protection box is opened, it is convenient to drive the driving hand wheel 701 to rotate or to inspect the reflux extraction mechanism 2;

[0042] In actual application, the liquid level sensor 5 transmits the signal to the external controller through a cable, and the external controller can directly control the working state of the water pump 202.

[0043] When in use, all components are in the initial installation state, and the medium flows in the transmission pipeline 1. Under normal conditions, part of the medium is located in the connector 707 and the transmission cylinder 706, and is sealed by the sealing seat 708. When the medium is accidentally transmitted at high pressure, the sealing seat 708 will be automatically lifted up. With the assistance of the displacement rod 709 and the positioning sleeve 710, the movement stability of the sealing seat 708 is ensured. There is a gap between the upward movement of the sealing seat 708 and the transmission cylinder 706, so that part of the medium enters the upper part of the sealing seat 708 and flows into the liquid storage tank 3 through the transmission cylinder 706, realizing the diversion and decompression operation, and ensuring the stable transmission of the medium in the transmission pipeline 1. In order to improve the quality and safety of the product, the staff can rotate the driving hand wheel 701 to drive the transmission screw 702 to rotate according to actual needs. With the cooperation of the fixed screw sleeve 703, the guide block 704 can be stably moved down on the surface of the fixed frame 711, and the connecting spring 705 is compressed to provide a greater supporting force for the sealing seat 708, thereby increasing the medium diversion pressure threshold, which is more in line with the actual needs of users. The liquid level sensor 5 can also be set to detect the liquid level value. When the amount of medium stored in the liquid storage tank 3 reaches the preset value, the liquid level sensor 5 sends a signal to the external controller to control the operation of the water pump 202, and cooperate with the suction tube 203 to lead the medium in the liquid storage tank 3 out.

[0044] In summary: the ground source heat pump buried pipe well pressure flow regulating device, by setting a reflux extraction mechanism 2, a liquid storage tank 3, a liquid level sensor 5 and an elastic pressure relief mechanism 7, solves the problems that the existing pressure flow regulating device cannot perform diversion and pressure reduction processing, cannot separately drain and store excess media in the pipeline, and cannot flexibly change the adjustment range, and has general applicability to different media and different pipelines.
