Background technology
Big capacity four-way change-over valve generally is applied in the heat pump type air conditioner.Common big capacity piston type four-way change-over valve is made up of pilot valve and main valve, main valve comprises valve body, be positioned at the piston of valve body and be arranged at two end caps at valve body two ends, the valve body of main valve, piston and end cap are formed left and right two cavitys, pilot valve is communicated with the cavity of main valve by wireway, be respectively arranged with valve on the wireway, be provided with the exhaust apparatus that to close between valve and the main valve cavity; Piston mainly utilizes the inner system's pressure reduction that exists of four-way change-over valve to carry out mobile working, owing to the reason of pressure reduction make in the valve body oil film easily by band from, cause piston under oil-free lubrication, to move; After if four-way change-over valve is stopped using a period of time, piston will be pulled in valve body and the stuck valve that makes can't operate as normal.
The utility model content
The purpose of this utility model is exactly will overcome that aforementioned four-way change-over valve exists because scarces lubricating oil makes piston stuck defective easily, and the novel big capacity four-way change-over valve of the interior feed lubricating oil of the past valve body of a kind of energy is provided.For this reason, the utility model is by the following technical solutions:
A kind of novel big capacity four-way change-over valve, mainly form by main valve and pilot valve, pilot valve is communicated with the cavity of main valve by wireway, main valve comprises valve body, be arranged at piston and two end caps that are arranged at the valve body two ends in the valve body, piston is I-shaped member rotation 90 degree that stagger by two view shapes and is connected as a single entity and constitutes, it is characterized in that: the outer surface of described piston is provided with oil groove, described valve body is provided with the oil filler point that connects the valve body inside and outside wall, the aperture of this oil filler point is facing to described oil groove, the member of described formation piston is connected as a single entity by weft element and vertical body and forms, make the member view be I-shaped, vertical body both sides are cavity, member is provided with nozzle opening, this nozzle opening one end is communicated with described oil groove, and other end aperture makes oil can spray to cavity facing to cavity, because cavity directly is communicated with valve interior wall, makes lubricating oil can be diffused into the valve interior wall lubricate.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Described nozzle opening is arranged on the described vertical body, and the aperture of nozzle opening directly facing to valve interior wall, can directly run on the valve interior wall oil, better lubricate.
Described four-way change-over valve also comprises oil feed line, and this oil feed line is connected with described oil filler point.
On the described oil filler point pipe joint is installed, described oil feed line is connected with this pipe joint.
Described oil feed line is provided with two ball valves, can be used to blind off a line.
Oil feed line between described two ball valves is provided with magnetic valve, is used to control the conveying capacity of oil by the time of opening of controlling magnetic valve.
Oil feed line between described two ball valves is provided with oil strainer, is used for removing the impurity of oil.
When the utility model used, oil feed line was connected in the compressor oil separator, provides pressure oil as lubricating oil by the compressor oil separator.
Use the utility model can reach following beneficial effect: carry the oil that is used to lubricate by the oil supply system that oil feed line, oil groove and nozzle opening are formed in valve body, to the piston lubricate, it is stuck to have avoided piston to take place in valve body.
