TH165735A - Pressure reducing device - Google Patents

Abstract

It is provided as a pressure relief device (10) to reduce the pressure of the cooled refrigerant. By the condenser in the refrigeration cycle to deliver the refrigerant to the evaporator, where the area where The minimal clearance between needle valve (4) and port valve (21) can be precisely determined inside the cylinder main body frame (1), including the primary chamber (11) that is welded to it. to Condensers and secondary flanges (12) bonded to evadorators, molded valve fitting assemblies (2) with valve port (21) and cylindrical lead assembly ( 3) that are assembled with The valve fitting assembly (2) will be provided with a coil spring (6) to power the needle valve (4) to the valve port side (21) to be provided inside the lead assembly (3) section. The needle (41) of the needle valve (4) extends from the valve port (21) to the primary chamber (11), the tip (41a) of the needle port (41) is aligned with the stop assembly. In this way, one position of the stopper assembly (7) along the axis (L) is adjusted by the degree of screw fastening to the piece. Valve fitting assembly (2)

Claims (4)

1. A pressure reducing device, provided between the condenser and evaporator in the cycle. Cooling, to reduce the refrigerant pressure that is cooled by the condenser and to Deliver refrigerant to the evaporator, the device includes: a main body frame consisting of a primary chamber welded to the condenser and a secondary chamber to the Iwapore. Router Valve mounting assembly, formed with the valve port, inside the seat. The main body frame and between the primary and secondary rooms Valve body to allow the opening level of the valve port to be variable by Moving along the axis of the valve port Spring assembly to power the valve body to the primary assembly and the stopper assembly positioned opposite the valve body end on the primary chamber side where the valve body is not fixed on the mounting assembly. Set the valve with the upper end. The primary chamber side was positioned by inserting it into the end of the valve body on the side. The primary chamber from the secondary chamber side enters the valve port and allows the upper end to the chamber side. Primary to be aligned with the stopper assembly. 2. Pressure reducing device according to claim 1, where the valve body is a needle valve where the upper end The primary chamber is the tip of the needle section of the needle valve and the end is positioned. By allowing the tip of the needle section to protrude from the valve port to the primary chamber and Allows the end of the needle section to jot down with the stopper assembly. 3. The pressure relief device according to claim 1 or item 2, where the valve fitting assembly will be formed. Up with a screw hole with a female screw portion on the primary chamber side, while the stopper assembly with Significantly columnar shapes are formed with the male screw portion on the surface along the Its circumference includes axial entry holes and screwing of the stopper assembly with holes. Screws are allowed for fixing the stopper assembly to the valve fitting assembly. 4. Pressure reducing device according to any one of Claims 1 to 3, a device consisting of a cylindrical guide assembly, aligned with the axis of the The valve port is positioned on the secondary chamber side inside the main body frame, to direct the valve body. By the leading holes in the columns Where the space between the guide assembly and the valve body cover forms a cavity. Flow on the main body to deliver the cooling cartridge from the port valve to the secondary chamber, free space. Behind the valve body, inside the pilot assembly, forms a medium pressure chamber and cavity. Imported with medium pressure to inlet refrigerant from port valve into Moderate pressure will be prepared.
