AI Technical Summary

⚠Technical Problem

Existing valves suffer from high costs, complex structures, difficult cleaning, uneven clearance leading to unstable product quality, susceptibility to pressure peaks, and frequent malfunctions during manufacturing and operation.

⚗Method used

The valve structure consists of a sleeve and a cone. The inner surface of the sleeve gradually tapers, and the outer surface of the cone matches it. Precise clearance control is achieved through axial adjustment. Combined with force or path control adjustment elements, the number of components is reduced and reliability is improved.

🎯Benefits of technology

It achieves a simple structure, low cost, easy cleaning, good gap uniformity, strong resistance to peak pressure, reduces the risk of failure, and is suitable for high-pressure process conditions.

Abstract

A valve comprising a housing (1), a valve body (2) having a fluid inlet (5) and a fluid outlet (6), the valve body (2) comprising a first valve element (3) and a second valve element (4) arranged in the housing (1), a gap (14) formed between the valve elements (3, 4), the first valve element (3) being configured as a sleeve (3) having an inner surface tapering at least section-wise towards the fluid outlet (6), the second valve element (4) being configured as a cone (4) mounted in the sleeve (3) having the same inclination as the inner surface of the sleeve (3) to form the gap (14), an annular space (8) leading to the fluid outlet (6) being formed between the sleeve (3) and an inner surface of the housing (1), the sleeve (3) having a through hole (10) towards the annular space (8) and the cone (4) having a through opening (9) towards the fluid inlet (5), the sleeve (3) and the cone (4) being axially adjustable relative to each other.
