An electromagnetic ball valve with positioning

Abstract

The invention provides an electromagnetic ball valve capable of positioning. The electromagnetic ball valve capable of positioning includes a valve body, a valve seat assembly, a valve core and an electromagnetic assembly, wherein an oil channel A, an oil channel P, an oil channel T are arranged on the valve body, and a valve body cavity is formed in the valve body. The valve seat assembly is arranged in the valve body cavity, the valve seat assembly is provided with channels, the channels are correspondingly in communication with the oil channel A, the oil channel P and the oil channel T, andthe valve seat assembly is provided with a positioning mechanism. The valve core is moveably arranged in the valve seat assembly, a clamping structure is arranged on the valve core, and the clampingstructure is matched with the positioning mechanism to keep the working position of the valve core. The electromagnetic assembly is connected with the valve core to switch the working position of thevalve core. The electromagnetic ball valve capable of positioning can realize the reliable work of the two positions, is simpler in structure, and convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to an electromagnetic ball valve with positioning. Background technique [0002] The control valve is one of the main components of the hydraulic system, and the electromagnetic ball valve is one of the control valves. Solenoid ball valve is an electromagnetic control valve with a spherical spool. In addition to all the characteristics of solenoid valves, it also has some unique characteristics. It uses the thrust of the electromagnet as the driving force to push the steel ball to realize the on-off of the oil circuit. It is suitable for the hydraulic system with various mineral oils as the working medium to realize the pilot control without leakage. It can also be used as the direction control of other actuators when the flow-pressure drop characteristic requirements are met. [0003] For example, the Chinese utility model patent with the announcement number CN202048222U and the n...

Problems solved by technology

Although the above invention can switch between the two working positions through whether the electromagnet is energized or not, in actual industrial automation applications, for example, if both working positions need to be maintained for a long time, the working position of the electromagnet without power is easy to realize , but the maintenance of the working position where the electromagnet needs to be energized needs to be maintained by energizing the electromagnet for a long time. Long-term energization of the electromagnet will cause the electromagnet coil to heat up, and the service life of the coil is relatively short, which will cause the electromagnetic ball valve to be prone to failure. , high maintenance cost
