Abstract
The invention provides a three-position three-way electric-control stop valve which comprises a valve body, a bottom plate and a valve deck. The top end of the valve body is fixedly connected with the valve deck in a sealed mode. The bottom end of the valve body is fixedly connected with the bottom plate in a sealed mode. Two identical two-position two-way stop valve structures are arranged inside the valve body side by side in the longitudinal direction. The two two-position two-way stop valve structures are located inside a left control cavity and a right control cavity of the valve body respectively. According to the three-position three-way electric-control stop valve, the requirement for filtering accuracy of compressed air is lowered, and secondary purification of the compressed air for work is not needed. Both a plug core and a valve element of the three-position three-way electric-control stop valve are installed vertically, eccentric wear is avoided, air leakage faults caused by eccentric wear of the valve element are reduced, and the reliable service life of a product is prolonged. The three-position three-way electric-control stop valve can be operated manually, air exhaust is not needed during maintenance, and on-site maintenance and overhaul for an electromagnetic pilot operated valve are facilitated.
