Temperature sensing bulb temperature control device

Abstract

The invention relates to a temperature sensing bulb temperature control device. The temperature sensing bulb temperature control device comprises an air valve and a temperature sensing bulb. The temperature sensing bulb is filled with inert gas. The make-and-break state of refrigerant inside the air valve is adjusted through change of the temperature and volume of the inert gas, so that temperature adjustment is achieved. A temperature control mechanism is arranged at the upper end of the air valve. A valve element bracket is arranged above a first vent hole. A transmission rod pushes a steelball under the effect that the transmission rod is subjected to the gas pressure inside the valve so that the make-and-break state of the first vent hole and a second vent hole can be achieved. A fixing ring is in close contact with the transmission rod through a compression spring. By means of a membrane piece, the gas pressure change inside the temperature sensing bulb is transmitted to a transmission piece, and then, the transmission rod is controlled to move up and down through the compression spring. The temperature sensing bulb temperature control device is reasonable in structure and ingenious in design; the electric power is not used; the constant temperature can be adjusted and maintained automatically; the device is safe and convenient to use; the technical problems that in existing refrigeration equipment, a temperature control device is unreasonable in structure, the constant temperature cannot be adjusted automatically, and the temperature control device is unsafe to use are solved; and for the prior art, the good market prospect and development space are achieved.

Description

technical field [0001] The invention relates to a temperature control device for refrigeration equipment, in particular to a temperature control device for a temperature sensing package. Background technique [0002] Refrigeration equipment is now commonly used in industry, especially in some high-temperature and high-humidity environments. The quality of refrigeration equipment directly affects the health and work efficiency of workers. The temperature control device in traditional refrigeration equipment adopts digital display electronics Control, although the temperature display is clear, but there are the following problems: 1. In coal mines, the use of live equipment will cause electric sparks. When the underground gas concentration is high, it is easy to cause accidents; 2. In some occasions, the temperature control device is required to automatically adjust the temperature to maintain Constant temperature; Third, some temperature control devices have complex structure...
