Description

Technical Field

[0001] The utility model relates to the technical field of solenoid valves, in particular to a solenoid valve for ultra-low temperatures. Background Art

[0002] In the field of vacuum coating and composite current collectors, the temperature of the ultra-low temperature fluid refrigerant is minus 120 degrees Celsius. It flows to the place where cooling is required through the main valve (proportional valve). Each control area (that is, the tributary) will use a solenoid valve to control the switch.

[0003] However, ultra-low temperatures will also affect the use of solenoid valves, because silicone oil will wax inside the local pipeline under ultra-low temperature conditions, causing difficulty in opening the solenoid valve and failure to achieve complete closure when closing.

[0004] For this reason, a solenoid valve for ultra-low temperature is proposed. Utility Model Content

An installation assembly is provided on the solenoid valve body, and a semiconductor heating plate is provided in the installation assembly, and the installation assembly is used to fit the semiconductor heating plate with the bottom surface of the solenoid valve body.

[0008] Furthermore, the fixing assembly includes a threaded sleeve, a protective shell is fixedly installed on the end of the threaded sleeve, and an elastic pressure ring is provided in the protective shell. The threaded sleeve is threadedly sleeved on the connecting joint to fix the protective shell.

[0009] Furthermore, the mounting assembly includes a rectangular mounting plate fixedly mounted on the surface of the solenoid valve body, a mounting box is attached to the bottom surface of the rectangular mounting plate, bolts are inserted between the rectangular mounting plate and the mounting box for fixing the mounting box, several groups of springs are fixedly mounted on the inner bottom of the mounting box, and a push plate is fixedly mounted on the end of the spring.

[0010] Furthermore, when the semiconductor heating ring is installed, the elastic pressure ring is in a compressed state, and the end of the protective shell is tightly fitted with the end face of the solenoid valve body.

[0011] Furthermore, the push plate is located inside the installation box, and the push plate is arranged to slide vertically inside the installation box.

[0012] Furthermore, when the semiconductor heating plate is installed, the spring is in a compressed state, so that the semiconductor heating plate is in close contact with the bottom surface of the solenoid valve body.

[0013] The beneficial effects of the utility model are as follows:

[0014] By respectively sleeved two sets of semiconductor heating rings on the connecting joints, the end faces of the semiconductor heating rings are fitted with the surface of the solenoid valve body, and the semiconductor heating rings are fixedly installed through the fixing components, so that the semiconductor heating rings and the end faces of the solenoid valve body are tightly fitted, and the semiconductor heating plate is fixedly installed on the bottom surface of the solenoid valve body through the installation components.

More specifically, by respectively sleeved two groups of semiconductor heating rings 2 on the connecting joints 11, the end faces of the semiconductor heating rings 2 are fitted with the surface of the solenoid valve body 1, and the semiconductor heating rings 2 are fixedly installed through the fixing components 3, so that the semiconductor heating rings 2 and the end faces of the solenoid valve body 1 are tightly fitted, and the semiconductor heating plate 5 is fixedly installed on the bottom surface of the solenoid valve body 1 through the installation components 4. Before the solenoid valve body 1 is controlled to open by the main controller, the semiconductor heating rings 2 and the semiconductor heating plate 5 are controlled by the time controller to open in advance, thereby heating the solenoid valve body 1 to avoid the waxing of the silicone oil transported in the solenoid valve body 1 due to low temperature, so that the solenoid valve body 1 is stable and smooth when opening and closing.

[0026] The fixing assembly 3 includes a threaded sleeve 301, a protective shell 302 is fixedly installed at the end of the threaded sleeve 301, and an elastic pressure ring 303 is provided in the protective shell 302. The threaded sleeve 301 is threadedly sleeved on the connecting joint 11 to fix the protective shell 302. More specifically, by sleeve-mounting the semiconductor heating ring 2 on the connecting joint 11, the end face of the semiconductor heating ring 2 is fitted with the end face of the solenoid valve body 1. By sleeve-mounting the threaded sleeve 301 on the connecting joint 11, the protective shell 302 is sleeved on the surface of the semiconductor heating ring 2, and is fitted with the other end of the semiconductor heating ring 2 through the elastic pressure ring 303. Under the elastic force of the elastic pressure ring 303, the semiconductor heating ring 2 is tightly fitted and installed with the solenoid valve body 1.

[0027] The mounting assembly 4 includes a rectangular mounting plate 401 fixedly mounted on the surface of the solenoid valve body 1. The bottom surface of the rectangular mounting plate 401 is fitted with a mounting box 402. Bolts 403 are inserted between the rectangular mounting plate 401 and the mounting box 402 to fix the mounting box 402.
