Problems solved by technology
[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 tiny flow control mechanism, including a basic electromagnetic coil, base, ring seat, floating part, shrapnel and sealing ring structure; the sealing ring is used as a part to improve the opening and closing stability of the floating part. It is fixed on the floating part or the base, but the bonding strength of the current sealing ring is limited. Due to the high frequency of opening and closing of the floating part, the sealing ring will loosen after being impacted for a long time, which will affect the work of the flow control mechanism.

Embodiment Construction
[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0016] Such as figure 1 As shown in the present invention, a precision flow control structure with enhanced sealing includes an electromagnetic coil 6, a base 1, a ring seat 2, a floating component 3, a shrapnel 4 and a sealing ring 5; the shrapnel 4 is located on the base Above 1, the ring base 2 and the floating part 3 are located between the base 1 and the shrapnel 4, and the floating part 3 is located inside the ring base 2.
[0017] The outer circumference of the upper side of the base 1 is provided with a plurality of arc-shaped retaining walls, the upper surfaces of the plurality of arc-shaped retaining walls are flush, the ring seat 2 falls on the arc-shaped retaining walls, and the adjacent arc-shaped retaining walls An air intake opening structure is formed between the walls; of course, the base 1 may not be designed with a...

The invention discloses a sealing reinforced precise flow control structure. The sealing reinforced precise flow control structure comprises an electromagnetic coil, a base, a ring seat, a floating part, an elastic piece and a sealing ring. The elastic piece is located above the base, the ring seat and the floating part are located between the base and the elastic piece, the floating part is located on the inner side of the ring seat, a flow pass hole is formed in the base, and the lower portion of the floating part is matched with the flow pass hole. The sealing ring is fixedly arranged on the upper side of the base or the lower side of the floating part; when the sealing ring is arranged on the base, a glue filling groove is formed in the matching surface of the sealing ring or the base;and when the sealing ring is arranged on the floating part, the glue filling groove is formed in the matching surface of the sealing ring or the floating part. According to the sealing reinforced precise flow control structure, an air inlet control structure of a valve is optimized, and the glue filling groove is formed in the corresponding matching surface of the sealing ring, so that the use amount of an adhesive at the fitting part of the sealing ring is increased, the bonding strength is improved, the sealing ring is not easy to loosen, and the stability of flow change control is improved.
Description
technical field [0001] The invention relates to a precision flow control structure with enhanced sealing. 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 tiny flow control mechanism, including a basic electromagnetic coil, base, ring seat, floating part, shrapnel and sealing ring structure; the sealing ring is used as a part to improve the opening and closing stability of the floating part. It is fixed on the floating part or the base, but the bonding strength of the sealing ring is currently limited. Due to the high frequency of opening and closing of the floating part, the sealing ring will loosen after being impacted for a long time, which will affect the work of the flow control mechanism.
