Valve gate

Technical Field

The utility model relates to the technical field of valves, in particular to valve.

Background

Valves are plumbing accessories used to open and close a pipe, control flow direction, regulate and control parameters of the transport medium (temperature, pressure and flow). According to their function, they can be classified into shut-off valves, check valves, regulating valves, and the like. The valve is a control part in a fluid conveying system and has the functions of stopping, adjusting, guiding, preventing counter flow, stabilizing pressure, shunting or overflowing and relieving pressure and the like. Valves used in fluid control systems range in variety and size from the simplest shut-off valves to the variety of valves used in extremely complex autonomous systems. The valve can be used for controlling the flow of various types of fluids such as air, water, steam, various corrosive media, slurry, oil products, liquid metal, radioactive media and the like.

The existing valve and pipeline connection mode is generally that two corresponding flanges are connected and fixed through bolts, but the flanges are only sealed through an O-shaped rubber ring, so that the sealing performance is low, and leakage is easy to occur from the connection position.

The technical scheme of the utility model is realized like this: the utility model provides a valve, includes valve body, spheroid and the pipeline of being connected with the valve body, be equipped with medium channel in the valve body, the spheroid is established in the valve body, all be equipped with first ring flange on the both ends of valve body, be equipped with the second ring flange corresponding with first ring flange on the pipeline, be equipped with the sealing member between first ring flange and the second ring flange, the sealing member is including connecting gradually fixed part, connecting portion and the sealing part that sets up, cross-section "worker" style of calligraphy setting of sealing member, the sealing part is established in medium channel, be equipped with the recess corresponding with fixed part and connecting portion on first ring flange and the second ring flange, fixed part and connecting portion inlay and establish in the recess.

By adopting the technical scheme, the I-shaped sealing element is arranged between the flange plates, so that the contact surface between the sealing element and the two flange plates can be vertically arranged to be isolated and sealed; and the pipeline only needs to correspond the sealing member and insert in the recess when being connected with the valve body, and the rethread bolt carries out fixed connection, and the connected mode is light, simple.

The utility model discloses further set up to: one side of the sealing part facing the connecting part is tightly attached to the side wall of the medium channel.

Through adopting above-mentioned technical scheme, can effectually prevent that the medium from taking place to leak between sealing and the lateral wall of medium passageway, the leakproofness is better.

The utility model discloses further set up to: slopes are arranged on two sides of the sealing portion.

Through adopting above-mentioned technical scheme, reduce the sealing to the produced resistance of medium when flowing, make it flow more smooth and easy, light, the pressure energy of medium makes the sealing inseparabler with the lateral wall laminating of medium passageway, and the leakproofness is better.

The utility model discloses further set up to: the groove comprises a first groove and a second groove which are symmetrically arranged, the first groove is formed in the first flange, and the second groove is formed in the second flange.

By adopting the technical scheme, the sealing element is arranged in the middle of the pipeline and the valve body, and leakage caused by deviation or inconsistent sealing performance of two sides is prevented.

The utility model discloses further set up to: the fixing portion, the connecting portion and the sealing portion are integrally formed.

By adopting the technical scheme, the connecting strength is effectively improved, and the service life is prolonged.

The utility model discloses further set up to: and threaded holes are correspondingly formed in the first flange plate and the second flange plate.

Through adopting above-mentioned technical scheme, accessible bolt carries out fixed connection with the screw hole, and the connected mode is simple, effective.
