Homogenizing valve for high-pressure homogenizer

Abstract

The invention discloses a homogenizing valve for a high-pressure homogenizer. The homogenizing valve comprises a valve seat, an impact ring and a valve element, wherein a material channel is formed inthe valve seat; the inner side surface of the outlet end of the material channel is a first conical surface with a small front part and a large rear part; a step surface is arranged at a position, which is positioned at the outlet end of the material channel, of the peripheral surface of the valve seat; the impact ring is arranged on the step surface of the valve seat; the valve element is arranged on the rear end surface of the valve seat; the front end surface of the valve element is in contact with the rear end surface of the valve seat, and the contact surface of the front end surface ofthe valve element and the rear end surface of the valve seat is positioned in the impact ring; a second conical surface with a small front part and a large rear part is formed on the periphery of thefront end surface of the valve element. According to the homogenizing valve disclosed by the invention, the flowing directions of materials at the outlet end of the material channel of the valve seatand the front end surface of the valve element are adjusted, so that the materials impact the inner ring surface of the impact ring along a certain inclination angle, the shear force and impact forceof the materials on the impact ring are reduced, the homogenizing effect is guaranteed, the service life of the impact ring is prolonged, and the continuity of product production is guaranteed.

Description

technical field [0001] The invention relates to the technical field of homogenizers, in particular to a homogenizing valve for a high-pressure homogenizer. Background technique [0002] The high-pressure homogenizer is a mechanism that uses a reciprocating pump as the power to transport materials. It transports liquid materials or solid particles with liquid as the carrier to the working valve part. After shearing, collision, cavitation, turbulent vortex, etc., the liquid materials, etc. Obtain an ultrafine and uniformly mixed state, and then send it to the next process. After the homogenization process, the uniformity and stability of the product can be improved, the retention period can be increased, and the reaction time can be reduced, thereby saving a large amount of catalysts or additives, and can also change the consistency of the product and improve the taste and color of the product, so it is widely used. Production and processing of food, dairy products, beverages...

AI Technical Summary

Problems solved by technology

[0003] Existing homogenizing valves for high-pressure homogenizers have to bear relatively large shearing force and impact force during operation, especially the damage to the impact ring that plays a role in pressure relief is very large, which shortens the service life of the impact ring. Frequent replacement seriously affects the continuity of product production

The current homogenizing valve is usually made of high-hardness metal materials, and the cost is relatively high. If it is replaced frequently, it will undoubtedly increase the production cost
