Abstract

The invention provides a valve element structure for improving passing flow, and belongs to the field of reversing valve manufacturing. The valve element structure is installed in a shell in a sliding mode, a high-pressure oil port and at least one working oil port are formed in the shell, a sliding hole is formed in the shell, and a valve element is arranged in the sliding hole in a sleeved mode and seals the sliding hole through the radial surface of the valve element. The valve element slides so that a gap can be formed between the axial end surface of the valve element and the sliding hole, and the gap is used for communicating the high-pressure oil port with the working oil port. A concave flow guide groove is formed in the axial end surface of the side, facing the sliding hole, of the valve element, and the bottom of the flow guide groove is provided with a smooth arc-shaped transition curved surface. Under the condition that an opening and a structure of a valve are not changed, by optimizing the valve element structure, under the same pressure drop, more flow can pass through, and the reverse resistance in the opening process of the valve element is effectively reduced.

Description

technical field [0001] The invention relates to valve manufacturing technology, in particular to a valve core structure used to increase flow rate, and belongs to the technical field of hydraulic equipment manufacturing. Background technique [0002] As a hydraulic component to control the on-off and reversing of the oil circuit, the reversing valve is widely used. The common reversing valve is a slide valve structure, and its spool slides in the valve body. By switching the direction of the spool, different oil ports are connected or closed. [0003] The material storage action of the injection molding machine is realized by the oil motor driving the screw to convey the raw material. The rotation of the oil motor is controlled by the reversing valve. Due to the physical characteristics of the raw material and the volume of the raw material to be transmitted, the displacement of the configured oil motor is also different. As a result, the displacement of the pump is also di...
