[0002] The tube crimping machine is a hydraulic device used to crimp the hydraulic oil pipe joint assembly. It applies contraction force to the matching metal joint through the hydraulic system through the tube crimping machine mold, and firmly crimps the metal joint on the matching hydraulic oil pipe and rubber hose. The hydraulic valve is an automatic component operated by pressure oil. It is controlled by the pressure oil of the pressure regulating valve. It is usually used in combination with the electromagnetic pressure regulating valve. It can be used to remotely control the on and off of the oil, gas, and water pipeline systems of hydropower stations. It is often used for clamping, controlling, lubricating and other oil circuits. There are direct-acting type and pilot type, and the pilot type is mostly used.

[0004] However, the easily disassembled hydraulic valve of the utility model converts the pressure energy of the hydraulic oil into mechanical energy when in use, thereby obtaining the required linear reciprocating motion or rotary motion of the automated components for control. The hydraulic oil is prone to heat up due to frequent use, and the hydraulic valve lacks a heat dissipation mechanism, which can easily cause damage to the valve body, seriously reducing the practicality of the hydraulic valve and failing to meet usage requirements. Therefore, a portable pipe crimping machine high-pressure hydraulic valve structure is proposed to solve the above-mentioned problems. Utility Model Content
