The invention relates to the technical field of reversing valves, and discloses a three-way reversing valve with an energy storage valve seat, which includes a valve body, a valve core, an energy storage valve seat, an arc-shaped pressing piece, a screw, and an energy storage canted coil spring , the valve core is located in the valve body, an energy storage valve seat is installed on the inner wall of the valve body, and the energy storage valve seat is fixed on the valve body with arc pressing pieces and screws. The valve core of the three-way reversing valve squeezes the valve seat to form a seal, but the valve core and the valve seat will be severely worn for a long time. This patent designs a three-way reversing valve with an energy storage valve seat. The energy storage valve The seat is an elastic structure and is made of elastic material, which reduces the friction and shear force suffered by the valve core when it rotates, and the energy-storage inclined coil spring inside the energy-storage valve seat has good rebound performance, which avoids the valve when it is sealed. The high level of stress caused by the long-term extrusion of the core and the energy storage valve seat reduces the magnitude of the torque generated during the rotation of the valve stem and the wear on the valve core, prolonging the service life of the valve.
Description
technical field [0001] The invention relates to the technical field of reversing valves, in particular to a three-way reversing valve with an energy storage valve seat. Background technique [0002] The three-way reversing valve of the mud-water shield adapter is sealed by the valve core extruding the valve seat to prevent the mud-water mixture from flowing through the gap between the valve core and the valve body and entering other pipelines. At present, domestic enterprises have not fully grasped the mud-water shield adapter tee. Reversing valve technology basically adopts imported products and technologies. [0003] During the working process of the three-way reversing valve, there are problems such as particles entering the sealing ring and destroying the sealing structure, resulting in seal failure, excessive torque of valve opening and closing friction, severe valve core wear, and valve core stuck. In the patent CN105697819A, the valve seat adopts Solid structure, lon...
