Description

Technical Field

[0001] This utility model relates to the field of flow-limiting temperature measuring valve technology, and in particular to a flow-limiting temperature measuring valve that is easy to control temperature. Background Technology

[0002] Flow-limiting temperature control valves are a typical application of flow regulating valves in temperature control. They control the inlet flow rate of primary heat (or cold) medium in heat exchangers, air conditioning units, or other heat- or cold-using equipment to control the outlet temperature. The flow-limiting valve controls its opening and closing through spring preload and the ratio of medium velocity to pressure. When the medium velocity in the pipeline exceeds the set value, the valve automatically closes to prevent accidents from occurring or escalating. When the fault is cleared or the flow rate returns to normal, the valve automatically opens. By adjusting the valve's opening degree, the flow rate of the heat (or cold) medium entering the equipment is controlled, thereby regulating the equipment's outlet temperature. When the load changes, the valve automatically adjusts its opening degree to eliminate the impact of load fluctuations on temperature.

[0003] Existing flow-limiting temperature measuring valves are typically connected to the pipeline via flange bolts, which makes subsequent disassembly, maintenance, or replacement cumbersome. Therefore, we propose a flow-limiting temperature measuring valve that facilitates temperature control. Utility Model Content

[0022] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1-5 This utility model provides a flow-limiting temperature measuring valve that facilitates temperature control, including a flow-limiting temperature measuring valve 1. A fixing thread 2 is provided on the outer side of the end surface of the flow-limiting temperature measuring valve 1. A fixed end plate 4 is welded to the end of the flow-limiting temperature measuring valve 1. A movable fastening mechanism 3 is movably sleeved on the outer side of the end surface of the flow-limiting temperature measuring valve 1. A second connecting end plate 5 is connected to one side of the fixed end plate 4 through the movable fastening mechanism 3. A sealing gasket 6 is provided between the fixed end plate 4 and the second connecting end plate 5. A U-shaped groove 7 is provided on the edge of both the fixed end plate 4 and the second connecting end plate 5. A fixed limiting groove 8 is provided on the side of the second connecting end plate 5 away from the fixed end plate 4. The side of the second connecting end plate 5 away from the fixed end plate 4 is welded to an external water supply pipe.

[0025] The top of the flow-limiting temperature measuring valve 1 is fixedly connected to a second connecting mounting base 9. The outer side of the second connecting mounting base 9 is symmetrically provided with a first fixing slot 10. The inner side of the first fixing slot 10 is movably connected to a movable plug 11. The top of the movable plug 11 is fixedly connected to a connecting top cover 12. The outer side of the movable plug 11 is provided with a second fixing slot 13. Both ends of the second connecting mounting base 9 are fixedly connected to a connecting limiting mechanism 14.

[0026] The movable fastening mechanism 3 includes a movable mounting half-ring 31 symmetrically located on the outer side of the end surface of the flow-limiting temperature measuring valve 1. A first connecting end block 32 is fixedly connected to the end of the movable mounting half-ring 31. A first connecting mounting seat 33 is fixedly connected to one side of the movable mounting half-ring 31. A movable connecting shaft 34 is movably connected to the inner side of the first connecting mounting seat 33. A movable pull rod 35 is movably connected to the inner side of the first connecting mounting seat 33 via the movable connecting shaft 34. A first connecting rod 35 is fixedly connected to the end of the movable pull rod 35 away from the first connecting mounting seat 33. A connecting end plate 36 has a movable mounting half-ring 31 with a fixed limiting block 37 fixedly connected to the side away from the first connecting mounting base 33. A movable connecting sleeve 38 is movably sleeved on the outer surface of the fixed limiting block 37. A threaded half-ring 39 is fixedly connected to the side of the movable connecting sleeve 38 away from the fixed limiting block 37. A second connecting end block 310 is fixedly connected to the end of the threaded half-ring 39. A rotating frame 311 is fixedly connected to the side of the threaded half-ring 39 away from the movable connecting sleeve 38. The adjacent first connecting end block 32 and the adjacent second connecting end block 310 are connected to each other. All connecting end blocks 310 are fastened together with bolts and nuts, allowing the rotating frame 311 to be rotated with a wrench. This causes the threaded half-ring 39 and the movable connecting sleeve 38 to rotate on the outer side of the end surface of the flow-limiting temperature measuring valve 1. Simultaneously, the movable connecting sleeve 38 can rotate on the outer side of the fixed limit block 37. The threaded half-ring 39 engages with the fixed thread 2 to move, thereby moving the fixed limit block 37, the movable mounting half-ring 31, the first connecting mounting seat 33, the movable connecting shaft 34, and the movable pull rod. The movable rod 35 and the first connecting end plate 36 are moved so that the first connecting end plate 36 can disengage from the inside of the fixed limiting groove 8. Then, the movable rod 35 drives the movable connecting shaft 34 to deflect inside the first connecting mounting seat 33, so that the movable rod 35 can disengage from the inside of the U-shaped groove 7. Thus, the connection between the fixed end plate 4 and the second connecting end plate 5 is no longer established. This allows for the quick disassembly of the flow limiting temperature measuring valve 1 and the fixed end plate 4 for inspection, maintenance, or replacement. The structure is simple and the operation is convenient and quick.

[0027] The fixed limiting block 37 has an L-shaped cross-section. The outer surface of the fixed limiting block 37 fits against the inner surface of the movable connecting sleeve 38, which makes it easy for the movable connecting sleeve 38 to rotate stably on the outer surface of the fixed limiting block 37, and the operation is convenient.

[0028] The outer surface of the movable pull rod 35 is in contact with the inner side of the U-shaped groove 7, and the outer side of the first connecting end plate 36 is in contact with the inner side of the fixed limiting groove 8, so that the movable pull rod 35 can be stably locked in the inner side of the U-shaped groove 7, and the first connecting end plate 36 can also be stably locked in the inner side of the fixed limiting groove 8, making operation convenient.

[0029] The connecting limiting mechanism 14 includes a movable mounting block 141. A fixed guide groove 142 is provided inside the movable mounting block 141. Fixed positioning blocks 143 are symmetrically arranged at the top of the movable mounting block 141. A bidirectional threaded rod 144 is movably connected inside the fixed positioning block 143. Connecting limiting discs 145 are fixedly connected to both ends of the bidirectional threaded rod 144. A fixed connecting rod 146 is fixedly connected to the side of one of the connecting limiting discs 145 away from the bidirectional threaded rod 144. A rotating block 147 is fixedly connected to the other end of the fixed connecting rod 146. A movable mounting arm 148 is threadedly connected to the outer surface of the bidirectional threaded rod 144. A fixed connecting arm 149 is fixedly connected to the bottom of the movable mounting arm 148 near the fixed positioning block 143. The fixed connecting arm 149 is located away from the movable mounting arm 148. One end is fixedly connected to a connecting limiting block 1410. The interior of the movable mounting block 141 has a through hole that matches the fixed connecting arm 149. The outer side of the bottom surface of the movable mounting arm 148 slides against the inner side of the fixed guide groove 142, which facilitates the rotation of the rotating block 147. This causes the fixed connecting rod 146, the connecting limiting plate 145, and the bidirectional threaded rod 144 to rotate, allowing the movable mounting arm 148 to move in opposite directions simultaneously on the outer side of the bidirectional threaded rod 144. This causes the fixed connecting arm 149 and the connecting limiting block 1410 to move, allowing the end of the connecting limiting block 1410 to disengage from the inner side of the second fixed slot 13. This removes the restriction on the position of the movable insert block 11, allowing the connecting top cover 12 to be disassembled, making the operation convenient.

[0030] The outer surface of the movable insert 11 is in contact with the inner side of the first fixed slot 10, and the outer surface of the connecting limiting block 1410 is in contact with the inner side of the second fixed slot 13, so that the movable insert 11 can be stably positioned inside the first fixed slot 10, and the end of the connecting limiting block 1410 can be stably inserted into the inner side of the second fixed slot 13, thereby limiting the connection.

[0031] The working principle of this utility model is as follows: During use, when it is necessary to disassemble, repair, maintain, or replace the entire flow-limiting temperature measuring valve 1, firstly, the rotating frame 311 is rotated using a wrench, causing the threaded half-ring 39 and the movable connecting sleeve 38 to rotate on the outer side of the end surface of the flow-limiting temperature measuring valve 1. At the same time, the movable connecting sleeve 38 can rotate on the outer side of the surface of the fixed limiting block 37. The threaded half-ring 39 cooperates with the fixed thread 2 to move, causing the fixed limiting block 37, the movable mounting half-ring 31, the first connecting mounting seat 33, the movable connecting shaft 34, the movable pull rod 35, and the first connecting end plate 36 to move, so that the first connecting end plate 36 can disengage from the inner side of the fixed limiting groove 8. Then, the movable pull rod 35 drives the movable connecting shaft 34 to deflect on the inner side of the first connecting mounting seat 33, so that the movable pull rod 35 can move from the U-shaped groove 7. The inner side of the fixed end plate 146 is disengaged, thus eliminating the connection between the fixed end plate 4 and the second connecting end plate 5. This allows for quick disassembly of the flow-limiting temperature measuring valve 1 and the fixed end plate 4 for inspection, maintenance, or replacement. When it is necessary to inspect or maintain the control components protected by the inner side of the connecting top cover 12, the rotating block 147 is rotated, causing the fixed connecting rod 146, the connecting limit plate 145, and the bidirectional threaded rod 144 to rotate. This allows the movable mounting arm 148 to move simultaneously in opposite directions on the outer side of the bidirectional threaded rod 144, thereby moving the fixed connecting arm 149 and the connecting limit block 1410. This allows the end of the connecting limit block 1410 to disengage from the inner side of the second fixed slot 13, thus eliminating the restriction on the position of the movable insert 11. This allows for disassembly of the connecting top cover 12. The overall structure is simple and the operation is convenient and quick.

[0032] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
