Description

Pressure follow-up valve Technical Field The utility model relates to the technical field of valves, in particular to a pressure follow-up valve. Background The temperature control valve generally comprises a valve body, a valve seat, a valve core, a temperature sensing element, an actuating mechanism and the like. The temperature sensing element senses temperature change, converts a temperature signal into a displacement signal or an electric signal, and drives the valve core to move through the actuating mechanism, so that the opening degree of the valve is changed, and the medium flow is regulated. However, when the traditional temperature control valve is used, the traditional temperature control valve is easy to age and damage, on one hand, high-temperature lubricating oil directly enters the gear box without being cooled to cause the continuous increase of the lubricating oil temperature, so that a unit is operated and even stopped due to high-temperature power limiting, and on the other hand, the lubricating oil with higher pressure enters the radiator to easily cause the risk of overpressure and even burst of the radiator, so that the pressure follow-up valve is provided for solving the technical problems. Disclosure of utility model 1. Technical problem to be solved The technical problem to be solved by the utility model is that when the traditional temperature control valve is used, high-temperature lubricating oil directly enters the gear box without being cooled, so that the unit is operated or even stopped due to high-temperature power limiting, and the risk of overpressure or even burst of the radiator is easily caused when the lubricating oil with higher pressure enters the radiator. 2. Technical proposal In order to solve the technical problems, the technical scheme is that the pressure follow-up valve comprises a valve body shell and a pressure follow-up valve, wherein the pressure follow-up valve is arranged on the inner side of the valve body shell and comprises a valve sleeve, a guide rod and a valve core, the valve core is sleeved on the outer side of the guide rod in a sliding mode, the guide rod is fixedly arranged on the inner side of the valve sleeve, the front end of the valve core is connected with a spring, the spring is sleeved on the outer side of the valve core, one end of the spring is connected with the tail end of the guide rod, a follow-up valve inlet is formed in the front end of the valve sleeve, and a follow-up valve outlet is formed in the side wall of the valve sleeve. As an improvement, a lubricating oil inlet is arranged on the inner side of the valve body shell, and the following valve inlet is communicated with the lubricating oil inlet. As an improvement, a radiator connector and a gear box connector are arranged on the inner side of the valve body shell, the lubricating oil inlet is communicated with the radiator connector, and the follow-up valve outlet is communicated with the gear box connector. As an improvement, the guide rod is connected with the valve sleeve through fine threads. As an improvement, the top end of the valve core is conical, and a mechanical seal is arranged between the valve core and the front end of the valve sleeve. 3. Advantageous effects Compared with the prior art, the pressure follow-up valve has the advantages that the pressure follow-up valve is designed for replacing the traditional temperature control valve, the overall external dimension of the follow-up valve is completely consistent with that of the temperature control valve, the temperature control valve can be directly replaced, and the original temperature control valve mounting block does not need to be removed; The lubricating oil does not need to be cooled, the pressure value reaches or exceeds the opening pressure of the follow-up valve, the follow-up valve is opened, a part of oil enters and passes through the follow-up valve and goes to the gear box, and the risk that the lubricating oil with higher pressure enters the radiator to cause overpressure and even burst of the radiator is avoided.
