Description

Integrated valve plate integrating liquid storage function Technical Field The utility model relates to the technical field of integrated valve plates, in particular to an integrated valve plate integrating a liquid storage function. Background An integrated valve plate is a compact device that integrates multiple fluid control elements (e.g., valves, pumps, sensors, etc.) and their flow passages into a single valve plate or block, and is widely used in hydraulic, pneumatic, cooling, or lubrication fluid control systems. The prior integrated valve plate, for example, a double-exhaust integrated valve disclosed in the patent application number 202022143825.2, mainly structurally comprises an integrated valve plate, wherein a valve cavity, an air inlet communicated with the valve cavity, an air inlet of a tower communicated with the valve cavity, an air outlet I and an air outlet II are formed in the integrated valve plate, a double-sided valve and a piston valve are arranged in the valve cavity, the double-sided valve is positioned between the air inlet and the air outlet II, when compressed air is introduced into the normally open end air inlet, the piston J closes the air outlet I after moving, and simultaneously the piston J drives the valve element I to move through a push rod II, so that a channel between the air inlet and the air inlet of the tower is opened, and a channel between the air outlet II and the air inlet of the tower is closed. When the normally open end air port is communicated with the atmosphere, compressed air is introduced into the normally closed end air port, the piston H moves, the ejector rod drives the valve element I to move, the valve element I drives the piston J to move through the ejector rod II, and the opening of the first exhaust port and the opening of a channel between the second exhaust port and the air inlet of the tower are realized. However, the liquid storage function is realized through the liquid storage tank which is manufactured independently in the traditional mode, then the liquid storage tank is installed and fixed on the valve plate through the fastening piece, and the sealing is realized through the sealing piece. Disclosure of utility model In order to solve the technical problems, the utility model provides the integrated valve plate integrating the liquid storage function, which has the advantages that the liquid storage function is realized by designing the structure of the valve plate, the installation characteristic is omitted, the overall cost is lower, the connection is firmer, the sealing characteristics of an inlet and an outlet are also omitted, and the sealing performance is better. The utility model discloses an integrated valve plate integrating a liquid storage function, which comprises a cover plate, a valve plate assembly and a filtering mechanism, wherein the valve plate assembly is arranged on the cover plate and is used for carrying out gas-liquid separation on a refrigerant, the filtering mechanism is arranged on the valve plate assembly and is used for filtering and drying the refrigerant, the high-pressure gas-liquid mixed refrigerant flowing out of an LCC enters the filtering mechanism through a flow passage, the filtering mechanism is used for filtering and drying the refrigerant, then the refrigerant enters the valve plate assembly through a notch, the valve plate assembly is used for carrying out gas-liquid separation on the refrigerant, and liquid enters other products from a lower side outlet.
