A heating chamber is provided inside the valve core, and a heating unit is provided in the heating chamber. The heating unit can use an electric heating wire and other devices. When the heating unit is heated, the heat is transferred to the surrounding of the valve core, so that the ice debris or ice cubes around the valve core melt, which is convenient for normal operation of the valve core to open and close the refrigeration equipment pipeline. The valve core is not easy to be damaged and has a long service life.

[0004] However, the valves of the above devices are generally exposed to the outside world and are easily turned by accident, resulting in the valves not being tightly closed, leading to leakage of the refrigeration equipment. Utility Model Content

DETAILED DESCRIPTION

[0017] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the present utility model, it should be noted that the terms "center", "up", "down", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. The present utility model is further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1-3 As shown, the special opening and closing valve device for industrial refrigeration equipment proposed by the utility model includes a valve body 1, to which an inlet pipe 2 and an outlet pipe 3 are fixedly connected, and also includes a driving locking mechanism 4 and an extrusion sealing mechanism 5 arranged on the valve body 1; the driving locking mechanism 4 includes a fixing block 6 and a valve stem 7, the fixing block 6 is arranged on the top wall of the valve body 1, and a positioning hole 8 is arranged on the fixing block 6, and a plurality of positioning holes 8 are evenly arranged on the outside of the valve stem 7, the valve stem 7 is threadedly penetrated on the top wall of the valve body 1, a turntable 9 is arranged at the top of the valve stem 7, and a positioning assembly 10 is arranged in the valve stem 7, and the turntable 9 is rotated to drive the valve stem 7 to rotate, and as the thread is screwed in, the valve stem 7 moves, driving the extrusion sealing mechanism 5 to close the connected pipeline, and at this time, the positioning assembly 10 is adjusted to fix the valve stem 7.

[0020] like Figure 3 As shown, the positioning assembly 10 includes an adjusting groove 11, a screw rod 12 and a push plate 13. The adjusting groove 11 is arranged in the valve stem 7. A connecting groove 14 is penetrated on the side wall of the adjusting groove 11. The connecting groove 14 is provided with multiple groups. The screw rod 12 is rotatably arranged in the adjusting groove 11. One end of the screw rod 12 penetrates the top wall of the adjusting groove 11 and is provided with a knob 20. A connecting block 15 is threadedly connected to the screw rod 12. The push plate 13 is sleeved on the valve stem 7.
