Description

Technical Field

[0001] This utility model relates to the field of heating control valve technology, specifically a control valve for urban heating radiators. Background Technology

[0002] Urban heating typically uses steam or hot water to heat radiators, thereby raising the indoor temperature and achieving a heating effect. For example, in a radiator temperature control valve disclosed in Chinese patent literature (patent number: CN202021257525.0), the valve body is directly installed on a single connecting pipe. The valve body can only control a single radiator. If the connecting pipe connects multiple radiators, it can only control multiple radiators to be locked or locked simultaneously. This results in a waste of heat and resources for radiators that are not in use.

[0003] Therefore, we propose a control valve for urban heating radiators. Utility Model Content

[0004] The purpose of this utility model is to provide a control valve for urban heating radiators to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a control valve for urban heating radiators, comprising a first connecting pipe and a second connecting pipe, a third connecting pipe on the left side of the second connecting pipe, a fourth connecting pipe on the right side of the second connecting pipe, a first through hole in the middle of the top of the first connecting pipe, a plug in the first through hole, a fixing rod on the top of the plug, a first sealing plate on the lower right side of the fixing rod, a second sealing plate on the lower left side of the fixing rod, a threaded hole in the upper half of the fixing rod, a connecting plate on the upper right side of the fixing rod, a third sealing plate on the right end of the connecting plate, a guide plate in the upper part of the second connecting pipe, a second through hole at the top of the second connecting pipe, and a threaded rod in the second through hole.

[0006] Preferably, the guide plate has a guide hole in the middle, a first through groove at the right end of the guide hole, and a second through groove at the right end of the first through groove.

[0007] Preferably, the guide hole cooperates with the fixing rod, and the first through groove and the second through groove cooperate with the connecting plate and the third sealing plate, respectively.

[0008] Preferably, the threaded rod is connected to the threaded hole, the surface of the threaded rod inside the second connecting pipe is provided with threads, and a shaft seal is provided between the threaded rod and the top of the second connecting pipe.

[0009] Preferably, the second connecting pipe is connected to the top middle of the first connecting pipe, and connectors are provided at both ends of the first connecting pipe, the left end of the third connecting pipe, and the right end of the fourth connecting pipe.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This device rotates the threaded rod, which cooperates with the threaded hole to make the fixed rod move up and down. The fixed rod drives the first sealing plate, the second sealing plate and the third sealing plate to move up and down, so as to flexibly control the third connecting pipe and the fourth connecting pipe, heat different radiators, control the heating of the radiators connected to the third connecting pipe and the fourth connecting pipe, and avoid the waste of heat when the radiators are not in use.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4This utility model provides a technical solution: a control valve for urban heating radiators, including a first connecting pipe 1 and a second connecting pipe 2. A third connecting pipe 3 is provided on the left side of the second connecting pipe 2, and a fourth connecting pipe 4 is provided on the right side of the second connecting pipe 2. A first through hole 5 is provided in the middle of the top of the first connecting pipe 1. A plug 6 is provided in the first through hole 5. A fixing rod 7 is provided on the top of the plug 6. A first sealing plate 8 is provided on the lower right side of the fixing rod 7. A second sealing plate 9 is provided on the lower left side of the fixing rod 7. A threaded hole 10 is provided in the upper half of the fixing rod 7. The first connecting pipe 1, the third connecting pipe 3, and the fourth connecting pipe 4 are all connected to different radiators. Without rotating the threaded rod 15, the plug 6 blocks the first through hole 5, and hot water flows through the first connecting pipe 1 to heat one radiator. Rotating the threaded rod 15 causes it to engage with the threaded hole 10, thus securing the radiator. The fixed rod 6 moves the plug 6 downward to open the first through hole 5. The second sealing plate 9 and the third sealing plate 12 both move downward. The first sealing plate 9 loosens its seal on the third connecting pipe 3, and the third sealing plate 12 seals the fourth connecting pipe 4. Hot water flows from the first connecting pipe 1 through the first through hole 5 into the second connecting pipe 2, and finally into the third connecting pipe 3, heating the radiator connected to the third connecting pipe 3. If the threaded rod 15 is rotated in the opposite direction, the fixed rod 7 moves upward, and the first and second sealing plates 8 on the fixed rod 7 are positioned above the fourth connecting pipe 4. When hot water passes through the first connecting pipe 1, it simultaneously passes through the third connecting pipe 3 and the fourth connecting pipe 4, heating the radiators connected to the first connecting pipe 1, the third connecting pipe 3, and the fourth connecting pipe 4 at the same time. This device rotates the threaded rod 15, causing the first sealing plate 8, the second sealing plate 9, and the third sealing plate 12 to move up and down, flexibly controlling the third connecting pipe 3 and the fourth connecting pipe 4 to heat different radiators. This controls the heating of the radiators connected to the third connecting pipe 3 and the fourth connecting pipe 4, preventing heat waste when the radiators are not in use.

[0018] The guide plate 13 has a guide hole 16 in the middle, a first through groove 17 at the right end of the guide hole 16, and a second through groove 18 at the right end of the first through groove 17. The guide hole 16 on the guide plate 13 guides the movement of the fixed rod 6 so that the fixed rod 6 will not rotate during the up and down movement.

[0019] The guide hole 16 cooperates with the fixing rod 6, the first through groove 17 and the second through groove 18 cooperate with the connecting plate 11 and the third sealing plate 12 respectively. When the fixing rod 7 drives the third sealing plate 12 to move upward, the third sealing plate 12 and the connecting plate 11 can pass through the first through groove 17 and the second through groove 18. The guide plate 13 will not obstruct the movement of the third sealing plate 12.

[0020] The threaded rod 15 is connected to the threaded hole 10. The surface of the threaded rod 15 inside the second connecting pipe 2 is provided with threads. A shaft seal is provided between the threaded rod 15 and the top of the second connecting pipe 2. When the threaded rod 15 rotates, the threaded rod 15 itself will not move. At the same time, the shaft seal is provided to seal the threaded rod 15 and the second connecting pipe 2.

[0021] The second connecting pipe 2 is connected to the top middle of the first connecting pipe 1. Connectors are provided at both ends of the first connecting pipe 1, the left end of the third connecting pipe 3, and the right end of the fourth connecting pipe 4. The pipes leading to the radiator are connected through the connectors.

[0022] Working principle: The first connecting pipe 1, the third connecting pipe 3, and the fourth connecting pipe 4 are all connected to different radiators through pipes. Without rotating the threaded rod 15, the plug 6 blocks the first through hole 5. Hot water flows through the first connecting pipe 1 to heat one radiator. Rotating the threaded rod 15 engages with the threaded hole 10, causing the fixed rod 6 to move the plug 6 downwards, opening the first through hole 5. The second sealing plate 9 and the third sealing plate 12 both move downwards. The first sealing plate 9 loosens its blockage on the third connecting pipe 3, and the third sealing plate 12 blocks the fourth connecting pipe 4. Hot water flows from the first connecting pipe 1 through the first through hole 5 into the second connecting pipe 2, and finally into the third connecting pipe 3, heating the radiator connected to the third connecting pipe 3. Heating is performed by rotating the threaded rod 15 in the reverse direction, causing the fixed rod 6 to move upward and positioning the first and second sealing plates 8 on the fixed rod 6 above the fourth connecting pipe 4. When hot water passes through the first connecting pipe 1, it simultaneously passes through the third connecting pipe 3 and the fourth connecting pipe 4, heating the radiators connected to the first connecting pipe 1, the third connecting pipe 3, and the fourth connecting pipe 4 at the same time. This device, by rotating the threaded rod 15, causes the first sealing plate 8, the second sealing plate 9, and the third sealing plate 12 to move up and down, flexibly controlling the third connecting pipe 3 and the fourth connecting pipe 4 to heat different radiators. This controls the heating of the radiators connected to the third connecting pipe 3 and the fourth connecting pipe 4, preventing heat waste when the radiators are not in use.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
