Summary of the invention
The purpose of this utility model is to solve the deficiencies in the prior art, carries a kind of multifunction valve for screw air compressor of arch.
The utility model solves the technological scheme that its technical problem adopts:
A kind of multifunction valve for screw compressor, comprise the rectangular valve body in cross section and the structure of controlling temperature of being located at valve inner, the side of described valve body is provided with oil filter mount inlet, the bottom of valve body is respectively equipped with barrel of oil and gas interface and head interface, the two ends of valve body are respectively equipped with oil outlet and the filler opening being connected with the cooler of helical-lobe compressor, wherein head interface, oil outlet and filler opening are communicated with at valve inner, and described structure of controlling temperature is controlled the unlatching of oil outlet and filler opening or closed.
Multifunction valve oil filter mount inlet be used for installing oil filter, barrel of oil and gas interface is communicated with oil drum, head interface is communicated with the head of screw compressor, oil outlet is communicated with the import of cooler, filler opening is communicated with the outlet of cooler, when just start or oil temperature are lower than setting value, oil in barrel of oil and gas enters multifunction valve by barrel of oil and gas interface, then after filtering by oil, by head interface direct, take back and flow in head, when oil temperature is during higher than setting value, structure of controlling temperature is opened oil outlet and filler opening, the oil of higher temperature enters cooler and via head interface, is back in head after cooling again.The utility model is simple in structure, easy to install, can realize oil temperature and control, and can also realize the efficient connection of all parts.
As preferably, described structure of controlling temperature is comprised of spool, heat responsive element and spring.
As preferably, described barrel of oil and gas interface, head interface, oil outlet and filler opening are equipped with the convenient internal thread of installing.Installation and maintenance convenient disassembly is time saving and energy saving.
As preferably, the bore of described oil outlet and filler opening is identical or not identical.To meet the demand of different connecting pipelines.
The beneficial effects of the utility model are: the utility model is reasonable in design, easy to process, install and safeguard convenient disassembly, and joint efficiency is high, can significantly reduce helical-lobe compressor volume, to meet need of production by use of the present utility model; By the utility model, can reasonably control oil temperature, extend the working life of screw compressor.
