[0002] Thermostatic valves can be used to adjust the flow of hot water in the heating system to achieve the purpose of controlling the room temperature. Existing thermostatic valves use the principle of liquid expansion due to heat and liquid incompressibility to achieve automatic adjustment. When the temperature changes, the volume of the temperature-sensitive liquid in the thermostatic valve expands or contracts, causing the valve stem to reciprocate longitudinally, thereby reducing or increasing the fluid flow.

[0051] The cover plate 3 is disposed on the control seat, and has a connecting end and a locking end. The cover plate 3 is hinged to the control seat through the connecting end, and the cover plate 3 is clamped to the control seat through the locking end;

[0052] A clamping member 14 is provided on the control seat, and is used for clamping the cover plate 3;

[0053] The control mechanism is arranged on the control seat, and is used to drive the clamping member 14 to approach the locking end so that the cover plate 3 and the control seat are in a locked state.

[0054] It should be noted that the device also includes a valve body 1 arranged below the control seat, and the connection method between the control seat and the valve body 1 is the same as the prior art, which will not be elaborated here. In the above scheme, the cover plate 3 is arranged in an opening and closing manner. Compared with the existing integrated temperature control valve or bolt connection method, the device is provided with an openable and closable cover plate 3 on the upper surface of the control seat, and then the locking and opening of the control cover plate 3 are driven by the control mechanism. For example, when the temperature control valve is only checked at ordinary times, the cover plate 3 can be opened quickly, or only one side of the cover plate 3 can be opened to increase the inspection speed. Another way is that when the components in the temperature control valve need to be inspected and replaced, the cover plate 3 can be completely removed at this time to expose all the components inside the temperature control valve, so as to facilitate the inspection of each component and replace the damaged components.

[0055] Furthermore, the control seat includes:

[0056] The housing 2 is provided with a boss 5 inside, and the boss 5 is used to overlap the cover plate 3;

[0057] A mounting groove 12 is provided in the side wall of the housing 2, and the control mechanism is provided in the mounting groove 12;

[0058] There are multiple through holes 4 , which are all opened on the inner wall of the shell 2 and communicated with the mounting groove 12 . The clamping member 14 is slidably disposed in the through holes 4 .

[0059] In the above scheme, the housing 2 is rectangular, and when the cover plate 3 is placed, the lower surface of the cover plate 3 overlaps the protrusion, and the upper surface of the cover plate 3 is flush with the upper surface of the housing 2. The mounting groove 12 is buried inside the side wall of the housing 2, and the outline of the mounting groove 12 is a rectangular ring, and the through hole 4 is a rectangular hole. The number of the through holes 4 is the same as the number of the clamping parts 14.

[0060] Furthermore, the cover plate 3 includes:

[0061] A first opening and closing plate 301, a first connecting ring 305 is provided on one side of the first opening and closing plate 301;

[0063] The connecting rod 303 is sequentially inserted into the first connecting ring 305 and the second connecting ring 306. The first opening and closing plate 301 and the second opening and closing plate 302 are hinged through the connecting rod 303. Fixed blocks 304 are provided at both ends of the connecting rod 303. The connecting rod 303 is connected to the side wall of the shell 2 through the fixed blocks 304.

[0064] Furthermore, the first opening and closing plate 301 and the second opening and closing plate 302 have the same structure, wherein two first connecting rings 305 and two second connecting rings 306 are respectively provided, and the two first connecting rings 305 and two second connecting rings 306 are respectively arranged at intervals. By adding a connecting rod 303 to the first connecting ring 305 and the second connecting ring 306, the first opening and closing plate 301 and the second opening and closing plate 302 can be hinged. It should be noted that during maintenance, the second opening and closing plate 302 and the second opening and closing plate 302 can be independently deflected and opened. In addition, the first opening and closing plate 301 and the second opening and closing plate 302 can be deflected downward or upward, and the steering is flexible, which is convenient for opening the cover plate 3.

[0065] Furthermore, the cover plate 3 also includes:

[0066] There are multiple card slots, which are respectively opened on the side wall of the first opening and closing plate 301 away from the first connecting ring 305 and the side wall of the second opening and closing plate 302 away from the second connecting ring 306. The card slot is used to connect with the card connector 14, and the card slot is a rectangular slot. When the card connector 14 is inserted into the card slot, the card connection is completed, and the cover plate 3 is locked at this time. On the contrary, when the card connector 14 is extended out of the card slot, the cover plate 3 is unlocked, and the cover plate 3 can be opened at this time.

[0067] Furthermore, the control mechanism includes:

[0068] There are two control rods 13, and both control rods 13 are rotatably disposed in the mounting groove 12;

The clamping member 14 is fixedly arranged on the push plates 15. The control rod 13 drives the push plates 15 to move so that the clamping member 14 moves into the clamping groove. The control rod 13 is a bidirectional screw. One end of the control rod 13 extends out of the housing 2. The control rod 13 is threadedly connected to the push plates 15. The threaded parts at both ends of the control rod 13 are respectively threadedly connected to a push plate 15. When the control rod 13 rotates, the two push plates 15 will move in opposite directions, so that the push plates 15 can push the clamping member 14 out of or retract it into the through groove.

[0070] Furthermore, it also includes:

[0071] The adjusting member is arranged on the outer wall of the housing 2, and is fixedly connected to the end of the control rod 13 extending out of the housing 2, and is used to control the rotation of the control rod 13. The adjusting member includes: a knob 8, which is rotatably arranged on the outer wall of the housing 2, and is fixedly connected to the end of the control rod 13 located outside the housing 2; a rotating wheel 9, which is arranged on the outer wall of the housing 2, and is fixedly connected to the end of another control rod 13 located outside the housing 2; a transmission belt, which is arranged on the knob 8 and the rotating wheel 9, and is used to drive the rotating wheel 9 to rotate synchronously with the knob 8. It should be noted that in order to prevent the conveyor belt 10, the knob 8 and the rotating wheel 9 from being accidentally touched, a protective cover 11 needs to be installed outside the adjusting member.

[0072] Furthermore, the clamping member 14 is a clamping block, and the longitudinal section of the clamping member 14 is a right-angled trapezoid, a right-angled triangle or a rectangle.

[0073] Furthermore, the housing 2 further comprises:

[0074] A groove 6 is provided on the side wall of the housing 2, and the groove 6 is used to connect the connecting rod 303;

[0075] One end of the spring sheet 7 is fixedly disposed in the groove 6 . Two spring sheets 7 are symmetrically disposed in the groove 6 . The spring sheets 7 are clamped with the fixing block 304 .

[0076] In the above scheme, the side of the fixing block 304 is in a shape that matches the spring sheet 7. When the fixing block 304 needs to be placed in the groove 6, it is only necessary to press the fixing block 304, and the spring sheet 7 will clamp the fixing block 304. However, when the connecting rod 303 needs to be taken out, it is only necessary to deflect the first opening and closing plate 301 and the second opening and closing plate 302 of the cover plate 3 upward, and then pull the cover plate 3 upward. When connected, the middle and side edges of the cover plate 3 can be stably connected to the housing 2. When it needs to be opened, it can be disassembled by simply pulling it upward.
