Multi-channel circulating oil supply valve

Abstract

The invention discloses a multi-channel circulating oil supply valve. The oil supply valve comprises a rotating core and a stator arranged on the rotating core in a sleeved mode, the outer wall of the rotating core is in liquid sealing fit with the stator, a metering cavity is formed in the stator, a piston is arranged in the metering cavity and divides the metering cavity into a first cavity and a second cavity, 4N liquid passing openings are formed in the peripheral side of the inner wall of a rotating core cavity at equal intervals, 4N liquid outlets are formed in the peripheral side, corresponding to the section where the liquid outlets of a liquid-outlet pipe are located, of the inner wall of the rotating core cavity at equal intervals, 2N outlets are formed in the stator, every two opposite liquid outlets communicate with one outlet through a pipeline, and a rotating control device controls the rotating core to rotate 360 / 4N degrees each time. According to the oil supply valve, an oil-outlet annular groove in the outer diameter of an original rotating core is omitted, then multiple sets of oil-outlet pore channels are formed in the position of the original annular groove, namely the stator (a valve body) matched with the original annular groove, and one-valve multi-point quantitative oil supply can be achieved through the multiple sets of oil-outlet pore channels.

Description

technical field [0001] The invention relates to a multi-channel circulating oil supply valve. Background technique [0002] The Chinese patent ZL201410136561.4 discloses a quantitative liquid supply device. After years of application, this patent has achieved certain effects. However, in the face of different customers and different equipment, there are more or less oil injection points in the project. There are more than 1,000, according to the quantitative oil supply of one valve at one point, the valve group (quantitative liquid supply device) needs thousands of sets, so, first, the total cost of system investment is too high, which makes it unacceptable for users; second, the site space area is limited and not allowed. Secondly, if you want to use a progressive distributor with one in and multiple out to combine with a quantitative liquid supply device, this mode cannot realize the random change of the flow rate of the oil injection point within the range of the combina...

[0002] The Chinese patent ZL201410136561.4 discloses a quantitative liquid supply device. After years of application, this patent has achieved certain effects. However, in the face of different customers and different equipment, there are more or less oil injection points in the project. There are more than 1,000, according to the quantitative oil supply of one valve at one point, the valve group (quantitative liquid supply device) needs thousands of sets, so, first, the total cost of system investment is too high, which makes it unacceptable for users; second, the site space area is limited instead of allowing

Secondly, if you want to combine a progressive distributor with one-inlet and multiple-outlets and a quantitative liquid supply device, this mode cannot randomly change the flow rate of the oil injection point within the range of the combination area.
