But in the process of use, when the water flow is adjusted so that the valve core is rotated at a certain angle, the high-pressure water flow will generate an impact on the valve core when it flows through the hole on the valve core, and will act on the output of the motor through the valve core. Shaft, thus generating a bias pressure on the output shaft of the motor, which is easy to cause damage to the motor, resulting in a decrease in the stability of the subsequent motor control spool, thereby shortening the service life of the diverter valve

The invention discloses a water diversion valve for a water jet loom with high stability. The waist-shaped hole is connected through a through hole, and the side wall of the valve core is provided with two pumping grooves, and the opposite side walls of the two liquid pumping grooves are made of soft rubber material, and the two pumping grooves are made of soft rubber material. The liquid pumping tank is arranged symmetrically along the through hole, and a pumping device for pumping water is installed in the liquid pumping tank. In the present invention, the water pumping device composed of iron sheet, rubber soft inner wall and inductance coil can be used to feed pulse current to the inductance coil when the valve body is working, so that the water flow at the block of the valve core can be continuously pumped away. , which can greatly reduce the impact of high-pressure water flow on the valve core, thereby avoiding motor shrinkage and prolonging the service life of the water diversion valve.
Description
technical field [0001] The invention relates to the related technical field of water jet loom accessories, in particular to a high-stability water diversion valve for water jet looms. Background technique [0002] The water-jet loom is a shuttleless loom that uses a jet of water to pull the weft through the shed. It mainly distributes the high-pressure water flow to each waterway and nozzle through the water diversion valve. [0003] The water flow distribution of the water diversion valve mainly relies on the motor to drive the valve core to rotate at a certain angle, thereby changing the water flow of each waterway. But in the process of use, when the water flow is adjusted so that the valve core is rotated at a certain angle, the high-pressure water flow will generate an impact on the valve core when it flows through the hole on the valve core, and will act on the output of the motor through the valve core. Shaft, thus generating a bias pressure on the output shaft of th...
