Problems solved by technology

[0002] When the vacuum pump pumps gas containing a large amount of water and impurities, most of the accumulated water and impurities will accumulate in the lower part of the gas tank through pre-separation. When the water volume reaches a certain level, it is necessary to discharge the accumulated water and impurities in the pre-separator , and every time you drain water, you need to open the drain valve, which will cause serious leakage in the vacuum system, and often need to shut down the vacuum system to completely discharge the accumulated water and impurities

Abstract

The invention provides a two-position five-way negative pressure switching valve. The valve comprises a valve body and a valve element, wherein an inner cavity matched with the valve element in shapeis formed in the valve body, the valve element is limited in the inner cavity of the valve body, the outer surface of the valve element is tightly attached to the inner wall of the inner cavity of thevalve body, the valve body is provided with an inlet channel, a first outlet channel, a second outlet channel, a first ventilation hole channel and a second ventilation hole channel, and the first ventilation hole channel and the second ventilation hole channel are communicated with outside atmosphere respectively; when the valve element is located at a first working position, the inlet channel is communicated with the first outlet channel, the inlet channel is isolated from the second outlet channel, and the second outlet channel is communicated with the second ventilation hole channel; andwhen the valve element is located at a second working position, the inlet channel is communicated with the second outlet channel, the inlet channel is isolated from the first outlet channel, and the first outlet channel is communicated with the first ventilation hole channel. The valve is connected between a separator of a vacuum system and two water storage tanks, any working position can enableone water storage tank to be communicated with the separator and store water, and the other water storage tank is isolated from the vacuum system and drains water.

Description

technical field [0001] The invention relates to the technical field of simultaneous water collection and drainage in a vacuum system, and more precisely relates to a two-position five-way negative pressure switching valve. Background technique [0002] When the vacuum pump pumps gas containing a large amount of water and impurities, most of the accumulated water and impurities will accumulate in the lower part of the gas tank through pre-separation. When the water volume reaches a certain level, the accumulated water and impurities in the pre-separator must be discharged , and every time the drain is drained, the drain valve needs to be opened, which will cause a serious leak in the vacuum system, and it is often necessary to shut down the vacuum system to completely drain the accumulated water and impurities. If two water tanks are connected to the pre-separator, the two tanks will communicate with the pre-separator in turn, and the pre-separator will discharge the accumula...
