Problems solved by technology

Among them, the independent valve body structure is that the switching valve and the exhaust valve are arranged separately and connected by air pipes, which not only brings the disadvantages of loose structure and troublesome assembly, but also has the problems of air leakage at the interface, difficult maintenance and high manufacturing cost; In addition, whether it is a drying system with an independent valve body or a combined valve body, the two adsorption towers need to be switched back and forth during work, and one is used for high-pressure adsorption and the other is used for low-pressure regeneration. The molecular sieve used to adsorb water vapor will be damaged due to excessive pressure difference (direct change of air pressure from low pressure to high pressure), which will affect the drying effect, reduce work efficiency and increase production cost

Abstract

The invention relates to a combination valve. The combination valve comprises a valve body; an intake joint for connecting with an intake pipe is fixedly arranged on the valve body; the intake joint extends into the valve body; and a first joint and a second joint for connecting a gas pipe are fixedly arranged on the two sides of the valve body. The combination valve further comprises a switchingvalve, an exhaust valve, and a pressure equalizing valve for communicating with the first joint and the second joint. The combination valve is provided with a control part (a switching part, a pressure equalizing part and an exhaust part) for controlling operation of each valve body. The combination valve relates to the technical field of valve elements, is mainly applied to an absorption air drying system, can reduce the cost, simplifies circuits, prevents the joint gas leakage phenomenon, is easy to achieve intelligent control, can simplify the operation system structure in actual application, and improves the working efficiency.

Description

technical field [0001] The invention relates to the technical field of valve components, in particular to a combination valve. Background technique [0002] Valve components are widely used in the mechanical field as control components. For example, in the adsorption air drying system, switching valves and exhaust valves are used to control the flow direction and working process of the air in the system. The two cooperate with each other and are indispensable. In addition, the The adsorption air drying system described above is based on the core theory of high-pressure adsorption and low-pressure regeneration to complete the work. [0003] The switching valves and exhaust valves used in the widely used adsorption air drying system are mainly divided into two structures: independent valve body and combined valve body. Among them, the independent valve body structure is that the switching valve and the exhaust valve are arranged separately and connected by air pipes, which no...
