Endurance test device for temperature valve

Abstract

The invention discloses an endurance test device for a temperature valve. The endurance test comprises a high-temperature pool, a low-temperature pool and an electric control cabinet, wherein a thermocouple is respectively arranged out of the high-temperature pool and the low-temperature pool; a rotary air cylinder is arranged between the high-temperature pool and the low-temperature pool; a rocker is arranged on the rotary air cylinder, and one end of the rocker is connected with the rotary air cylinder while the other end of the rocker is provided with a fixing rod for fixing the temperature valve; the fixing rod is positioned on one side of the rocker close to the high-temperature pool and the low-temperature pool; the rotary air cylinder is provided with an electromagnetic valve for controlling the rotary air cylinder to work; the electric control cabinet is internally provided with a temperature controller which is respectively connected with the thermocouple and the electromagnetic valve through wires. The endurance test device disclosed by the invention is reasonable in design and simple in structure. By adopting two critical ambient temperatures simulating action of the temperature valve and by using electric heating as well as controlling at a constant temperature by using the temperature controller, the experimental requirements are achieved, so that the endurance test of the temperature valve is convenient and efficient, and the endurance test device is relatively high in reliability and low in cost and operating cost.

Description

technical field [0001] The invention belongs to the technical field of temperature valve detection in oil coolers, and in particular relates to a temperature valve durability test device. Background technique [0002] There is a temperature valve inside the oil cooler. When the oil temperature changes, the temperature valve will control the size of the valve according to the temperature change to adjust the work of the oil cooler. Therefore, whether the temperature valve works normally determines whether the oil cooler can work normally. Therefore, when designing the oil cooler, a durability test must be carried out on the temperature valve. The main function of this experiment is to observe whether the temperature valve of the oil cooler has any faults during the long-term operation. There is no special equipment for the experiment, and the high and low temperature impact box is generally used instead of the experiment, but there are the following problems: 1. The high and ...

[0002] There is a temperature valve inside the oil cooler. When the oil temperature changes, the temperature valve will control the size of the valve according to the temperature change to adjust the work of the oil cooler. Therefore, whether the temperature valve works normally determines whether the oil cooler can work normally. Therefore, when designing the oil cooler, a durability test must be carried out on the temperature valve. The main function of this experiment is to observe whether the temperature valve of the oil cooler has any faults during the long-term operation. There is no special equipment for the experiment, and the high and low temperature impact box is generally used instead of the experiment, but there are the following problems: 1. The high and low temperature impact box is a sealed device, which is inconvenient to observe the action of the temperature valve; 2. The heating and cooling speed of the high and low temperature impact box is too high. 3. The structure of the high and low temperature impact box is complex and expensive; 4. The operating cost of the high and low temperature impact box is relatively high; therefore, we need to design a device specially used for the temperature valve durability test
