Problems solved by technology

However, in actual operation, because the temperature control structure of the multi-functional integrated valve only changes the hot oil passage, not the passage to the cooler oil, so when the load of the screw compressor is lower than 40%, The temperature control function of the multi-functional integrated valve is insufficient

Abstract

The invention provides a multifunction integrated valve which can make the volumes of a hot oil channel and a cooler oil channel to change in inverse proportion, has high temperature control sensitivity and is suitable for the wider range of temperature control working condition. The invention has the technical scheme that the multifunction integrated valve comprises a valve body; the valve body is connected with an oil filter; an oil cut valve assembly and a temperature control valve assembly are embedded in the valve body; the temperature control valve assembly comprises a temperature control valve core; and the temperature control valve core is arranged in the temperature control valve cavity of the valve body. The multifunction integrated valve is characterized in that the valve body is provided with an annular step on the periphery of the temperature control valve cavity; the annular step and the temperature control valve core are matched to divide the temperature control valve cavity into a left cavity and a right cavity; and the periphery of the temperature control valve core is provided with a circular hole.

Description

technical field [0001] The invention relates to the technical field of control devices, in particular to a multifunctional integrated valve, in particular to a multifunctional integrated valve used for increasing the temperature control sensitivity range of an oil circuit of a screw compressor. Background technique [0002] The original oil cut-off valve, temperature control valve, oil filter, etc. of the screw compressor oil circuit system are all independent components, which are connected in a certain way through the pipeline to control the oil circuit system. In the prior art, the date of announcement is September 24, 2008, and the Chinese invention patent with the authorized announcement number CN201121588Y has disclosed a multifunctional integrated valve for the oil circuit system of a screw compressor. The oil filter and differential pressure switch are integrated in one valve body to complete the control function of the oil lubrication system of the unit under variou...
