Problems solved by technology

At present, in my country's pressure machinery market, there are many types of products, various structural forms, narrow application range, and single purpose. The output pressure is only determined by the structure of the pressure machinery itself and cannot be adjusted at all, resulting in energy waste and idle equipment.

Embodiment Construction

[0013] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0014] see figure 1 , 2 A mechanical normally closed pressure valve, a mechanical normally closed pressure valve, including a valve body 1, a sliding plate 3 and a circular sleeve 2, the sliding plate 3 is arranged on the right side of the valve body 1, the circular The sleeve 2 passes through the sliding plate 3 and the valve body 1, and is arranged in the middle of the sliding plate 3 and the valve body 1. On the upper side and the lower side of the circular sleeve 2, pressure adjustment bolts 4 are respectively installed to pass through. The valve body 1 and the sliding plate 3, the pressure adjusting bolt 4 is located between the valve body 1 and the sliding plate 4 and is covered with a pressure adjusting spring 7, and the pressure adjusti...

Abstract

The invention relates to a mechanical normally-closed pressure valve, which comprises more than twenty parts including a valve body, a sliding plate, a circular sleeve and the like, and is a pressure control valve used in a mechanical pressure machine. In the working state, the valve is opened, when the pressure of a squeezed material in pressure machinery achieves a pressure value set by a spring, the valves of a pressure control valve are pulled open by a delay switch, the squeezed material achieving certain pressure is squeezed out, and therefore the squeezed material can achieve a form base; and when the pressure of the squeezed material in the pressure machinery does not achieve the pressure value set by the spring, the upper and lower valves of the pressure control valve are closed and are in an off working state. The mechanical normally-closed pressure valve has a simple principle, is convenient to use, has a pressure control role and a safety protection role, and is an ideal pressure control device of the mechanical pressure machinery. Compared with the hydraulic system, the mechanical normally-closed pressure valve has the advantages of no environment pollution, simple structure, reliable pressure, safety, durability and low cost.

Description

technical field [0001] The invention relates to a valve structure, in particular to a mechanical normally closed pressure valve. Background technique [0002] my country is a developing country with more than 1.2 billion people. The consumption and demand of food and medicine are huge. Among them, the development and processing of agricultural products still has a lot of room for development. The development of vegetables, fruits, aquatic products, poultry and other foods It has great potential, and the processing of shaped food and medicine is inseparable from pressure machinery. According to the status quo and trend of this development, it is certain that the demand for pressure machinery in my country will increase. At present, in my country's pressure machinery market, there are many types of products, various structures, narrow application range, and single purpose. The output pressure is only determined by the structure of the pressure machinery itself and cannot be ad...
