Abstract

The invention discloses a stable opening and closing structure for a high precision flow valve. The stable opening and closing structure comprises a solenoid coil, a base, a ring seat, an opening andclosing assembly and a spring piece; the spring piece is located above the base, and the ring seat and the opening and closing assembly are located between the base and the spring piece; the opening and closing assembly is located on the inner side of the ring seat; the opening and closing assembly comprises a movable piece and a sealing ring fixedly arranged at the bottom of the movable piece; and the solenoid coil is located on the upper side of the spring piece. According to the scheme, a valve intake control structure is optimized, and the ring seat is arranged at the position of the movable piece, and plays a certain role in lifting of the movable piece, so that the movable piece is not deflected in the intake process; air can enter the lower side of the movable piece, and the workingstability of a solenoid valve is ensured; upward suction is generated for the movable piece by the solenoid coil, and downward elastic force is generated for the movable piece by the spring piece; the height of the movable piece can be fine-tuned, so that the opening degree of the valve is changed; the sealing ring is arranged at the bottom surface of the movable piece, and the valve airtightnesscan be ensured after power-off of the coil.

Description

technical field [0001] The invention relates to a stable opening and closing structure of a high-precision flow valve. Background technique [0002] Solenoid valve is the main part of fluid flow control. Solenoid valve generally attracts the magnetic core through electromagnetic coil, and controls the flow through the opening of the magnetic core. precision. [0003] A few days ago, the applicant applied for a small flow valve control mechanism, in which the sealing ring is designed on the base, and in order to cooperate with the air intake of the base, the sealing ring needs to have an air intake hole; but during the test, it was found that the sealing ring It is installed on the base, and the airtightness between the sealing ring and the base must also be considered, which has high requirements for the processing accuracy and assembly accuracy of the sealing ring, and the sealing ring is changed to a solid one, and fixed on the moving part. The underside of the sheet avo...
