Abstract

The invention relates to a multifunctional integration valve which can ensure the temperature control performance. The multifunctional integration valve comprises a valve body, an oil filter, an oil cut-off valve part embedded into the valve body, a temperature-controlled valve plug component, an oil cooler and a cavity end cover, wherein the inside of the valve body is provided with a temperature-controlled cavity; and the temperature-controlled valve plug component is arranged in the temperature-controlled cavity. The multifunctional integration valve is characterized in that an annular step is arranged in the temperature-controlled valve plug component; after the annular step and the temperature-controlled valve core component are matched, the temperature-controlled cavity is divided into a hot oil cavity and a cold oil cavity; the hot oil cavity is communicated with an oil filter; the cold oil cavity is communicated with the oil cooler; the circumferential surface of the temperature-controlled valve plug component is provided with oil outlets; the axial direction of the temperature-controlled valve plug component is provided with a driving device; and one end of the axial direction of the temperature-controlled valve plug component is closed, and the other end of the temperature-controlled valve plug component is communicated with a hot oil inlet.

Description

(1) Technical field [0001] The invention relates to the field of screw compressor oil circuit devices, in particular to a multifunctional integrated valve. (2) Background technology [0002] The existing multi-functional integrated valve of the screw compressor oil circuit system integrates the oil cut-off valve, temperature control valve, oil filter and differential pressure switch into one valve body to complete the oil lubrication system of the unit under various working conditions of the compressor. control function. However, in actual operation, due to the internal temperature control structure, only the hot oil channel is changed, and the channel to the cooler oil is not changed. Therefore, when the screw compressor is lower than 40% load Insufficient temperature control function. (3) Contents of the invention [0003] In view of the above problems, the present invention provides a multifunctional integrated valve, which can ensure its temperature control performan...
