Problems solved by technology

[0004] The present invention overcomes the existing dead corners inside the existing pressure regulating valves, where material accumulation is easy to breed bacteria due to incomplete cleaning at the dead corners, and most pressure regulating valves control the pressure by starting the regulating membrane and the electric valve positioner. It is prone to safety hazards and is not suitable for many fields with special requirements. A sanitary self-operated pressure regulating valve is provided. There is no dead angle inside, and the inside of the regulating valve is thoroughly cleaned, and there will be no material accumulation to breed bacteria. Phenomenon, the use of regulating valve is more hygienic, and can be widely used in food, beverage, dairy, pharmaceutical, brewing, beer and other fields with high hygienic requirements

Abstract

The invention provides a hygiene grade self-operated pressure regulation valve and aims to solve the problems that dead spaces in the conventional pressure regulation valves tend to breed bacteria, and the conventional pressure regulation valves are mainly characterized by electric control of pressure and has potential safety hazards in the using process, thereby being not suitable for many fields having special requirements. The hygiene grade self-operated pressure regulation valve comprises a valve body and a valve element component. The valve element component comprises a valve rod and a valve element installed at the lower end of the valve rod; the valve body comprises a guide cylinder and a regulation cylinder communicated with the guide cylinder. The regulation cylinder and the guide cylinder are connected to form the y-shaped valve body and a y-shaped valve cavity. The inner wall of the guide cylinder is provided with an arc-shaped protrusion near the valve element and the transitional edge connecting the arc-shaped protrusion and the inner wall of the guide cylinder is arc-shaped and smooth. A valve cover component and a connecting frame are connected to the upper end of the regulation cylinder. An execution mechanism is connected to the upper end of the connecting frame. The upper end of the valve rod penetrates through the valve cover component and is connected with the execution mechanism. A returning mechanism is connected to the valve rod between the execution mechanism and the valve cover component.

Description

technical field [0001] The present invention relates to a valve, more specifically, it relates to a sanitary grade self-operated pressure regulating valve without residual dead angle. Background technique [0002] The self-operated pressure regulating valve does not require external energy, and can work in places without electricity and gas. It relies on the pressure of the medium flowing through the valve to drive the valve to work automatically. It is convenient and energy-saving, and has been widely used in many fields. However, in some special fields, the requirements for regulating valves are higher, such as food, beverages, dairy products, pharmaceuticals, brewing, beer, etc. The valve bodies used in these fields require smooth, seamless, hygienic, and easy cleaning inside the valve body, but Many pressure regulating valves currently used have dead angles inside. Inadequate cleaning in the dead angles will cause material accumulation to easily breed bacteria, and most ...
