Technical Field

[0001] This utility model relates to the field of temperature control valve technology, specifically a sliding temperature control valve. Background Technology

[0002] Thermostatic valves are a typical application of flow control valves in the field of temperature control. Their basic principle is to control the outlet temperature of heat exchangers, air conditioning units, or other heat- or cold-using equipment by controlling the inlet flow rate of the primary heat (or cold) medium. When the load changes, the flow rate is adjusted by changing the valve opening to eliminate the effects of load fluctuations and restore the temperature to the set value. Utility Model Content

[0042] The present invention will now be described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0043] Please see Figure 1-11 The present invention provides a technical solution: a sliding temperature control valve, comprising a valve body 1, a valve cover 2, and an on / off assembly 3.

[0044] The valve body 1 includes a valve chamber 11, a channel 12 symmetrically arranged on both sides of the valve chamber 11, and a channel 2 13 perpendicular to the channel 12 and arranged on one side of the valve chamber 11.

[0045] A fixed flange 121 is provided at the end of channel 12 away from valve chamber 11.

[0046] A fixed flange 131 is provided at the end of channel 2 13 away from valve chamber 11. A limiting boss 132 is provided on the inner side of the connection between valve chamber 11 and channel 2 13. A limiting boss 133 is provided on the inner side of channel 2 13 away from valve chamber 11.

[0047] The valve chamber 11 has a circular groove 1101 and a circular groove 1102 inside. Circular groove 1101 is connected to one of the channels 12, and circular groove 1102 is connected to the other channel 12.

[0048] The valve cover 2 includes a cover plate 21, a threaded rod 22, and a hexagonal cover 23.

[0049] The cover plate 21 is fixed to the top of the valve chamber 11 away from the second channel 13. The threaded rod 22 passes through the cover plate 21 and is threadedly engaged with the cover plate 21. The threaded rod 22 is inserted into the valve chamber 11. The hexagonal cover 23 is fixed to the end of the threaded rod 22 away from the valve chamber 11.

[0050] The on / off assembly 3 includes a cylindrical valve 31, a valve core 32, a spring 1 33, and a spring 2 34.

[0051] The cylindrical valve 31 is slidably disposed in the valve chamber 11, and the central axis of the cylindrical valve 31 coincides with the central axis of the second channel 13. The channel opened in the valve chamber 11 for the cylindrical valve 31 to slide is adapted to the cylindrical valve 31. The inner diameter of the limiting boss 132 is smaller than the diameter of the cylindrical valve 31. A through groove 310 is opened on the side of the cylindrical valve 31. When the cylindrical valve 31 slides to the top of the valve chamber 11 away from the second channel 13, the through groove 310 and the circular groove 1101 are aligned. An inner support 311 is provided at one end of the cylindrical valve 31 near the second channel 13. A through hole 3110 is opened on the inner support 311 that coincides with the central axis of the cylindrical valve 31.

[0052] The valve core 32 includes a temperature sensing chamber 321, a widened boss 322, a conduit 323, a push rod 324, and a limiting plate 327. The temperature sensing chamber 321 is filled with a temperature-sensing material. One end of the conduit 323 is fixed to the open end of the temperature sensing chamber 321. The widened boss 322 is fixed to the outside of the junction of the temperature sensing chamber 321 and the conduit 323. The push rod 324 is slidably installed in the conduit 323 and one end is located outside the conduit 323. The limiting plate 327 is fixed to the outside of the end of the conduit 323 away from the temperature sensing chamber 321. The spring 33 is located on the outside of the conduit 323 and one end abuts against the limiting plate 327.

[0053] The conduit 323 is inserted into the through hole 3110, and the end of the spring 33 away from the limiting plate 327 abuts against the end face of the inner support 311 away from the channel 13.

[0054] The valve core 32 also includes a plunger 325 and a diaphragm 326. The plunger 325 is located inside the conduit 323 near one end of the temperature sensing chamber 321, and the diaphragm 326 is located at the junction of the temperature sensing chamber 321 and the conduit 323, dividing the temperature sensing chamber 321 and the conduit 323 into two parts.

[0055] A limiting plate 328 is fixed at the junction of the outer side of the temperature sensing chamber 321 and the widened protrusion 322. A spring 34 is located on the outer side of the temperature sensing chamber 321, and the two ends of the spring 34 abut against the limiting plate 328 and the limiting protrusion 133, respectively.

[0056] The end of the push rod 324 away from the temperature sensing chamber 321 abuts against the end of the threaded rod 22 that is inserted into the valve chamber 11.

[0057] In the initial state, under the elastic force of spring 33 and spring 34, valve core 32 drives cylindrical valve 31 to press against the bottom of cover plate 21. At this time, cylindrical valve 31 closes circular groove 1102, and channel 12 connected to circular groove 1102 is not flowing. Furthermore, through groove 310 is aligned with circular groove 1101, and liquid can enter from channel 2 13 and flow through through groove 310 and circular groove 1101 to channel 12 connected to it. This state is the normally closed state of the temperature control valve.

[0058] When the flowing liquid is overheated, the temperature sensor expands due to heat, and the diaphragm 326 deforms to push the plunger 325. The plunger 325 pushes the push rod 324 upward. The push rod 324 is restricted by the cover plate 21. Under the reaction force, the guide tube 323 moves downward as a whole. It pushes the spring 33 downward through the limiting plate 327. The spring 33 pushes the cylindrical valve 31 downward. At this time, the circular groove 1101 and the circular groove 2 1102 are both connected to the cylindrical valve 31, and the liquid can flow into the two channels 12. This state is the half-open state of the temperature control valve.

[0059] As the heat of the flowing liquid continues to rise until the cylindrical valve 31 moves to the limit boss 132, the circular groove 1101 closes and the circular groove 2 1102 opens, and the liquid flows through the channel 12 connected to the circular groove 2 1102. This state is the normally open state of the temperature control valve.

[0060] Through the above embodiments, the purpose of the temperature control valve to automatically control the valve's on / off state according to the temperature is achieved.

[0061] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the scope of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
