Description

Nut with built-in ultrahigh pressure check valve

Technical Field

The invention belongs to the technical field of high-pressure homogenizers.

Background

The high-pressure homogenizer is mainly used in the industries of medicine, food and chemical industry, and is used for preparing liposome, fat emulsion, nano suspension, microemulsion, lipid microspheres, emulsion, dairy products, infusion solutions, fat emulsion, cell disruption, high-pressure homogenization of fruit juice, fine chemical engineering and dyes.

The check valve for a conventional high-pressure homogenizer is usually connected to the fluid line as a separate component. The invention provides a nut with a built-in ultrahigh pressure check valve, which directly connects a high-pressure pump with a material container.

Disclosure of Invention

The invention aims to provide a nut with a built-in ultrahigh pressure one-way valve, aiming at simplifying the material pipeline of the existing high-pressure homogenizer.

The nut is characterized in that a material container and the ultrahigh pressure pump can be connected by only one nut internally provided with the ultrahigh pressure check valve, and the function of the check valve is realized at the same time.

Further, the nut with the built-in ultrahigh pressure one-way valve is characterized in that the rated pressure of the nut with the built-in ultrahigh pressure one-way valve is 100-300MPa, and the pressure range of the nut with the built-in ultrahigh pressure one-way valve is the same as that of a high-pressure homogenizer.

Furthermore, the nut with the built-in ultrahigh pressure one-way valve is characterized in that one end of the compression spring tightly supports the steel ball, so that the steel ball is matched with the inner part of the nut shell to form a sealing surface, and the other end of the compression spring is positioned and supported by the valve core.

Further, the nut with the built-in ultrahigh pressure check valve is characterized in that the thrust of the spring to the steel ball can ensure that the check valve is in a closed state when the nut is not in operation, and the check valve is opened under the action of negative pressure of the high-pressure pump when the nut is in operation to form a one-way conduction state.

Further, the nut with the built-in ultrahigh pressure one-way valve is characterized in that when the built-in one-way valve does not work, the normally closed thrust of the steel ball is provided by the compression spring.

Further, the nut with the built-in ultrahigh pressure one-way valve is characterized in that the nut with the built-in ultrahigh pressure one-way valve with a luer or the nut with the built-in ultrahigh pressure one-way valve with a sanitary quick connector can be used according to different purposes.
