Embodiment Construction

[0021] Such as figure 2 , image 3 and Figure 4 The new gas ballast valve shown is provided with a valve body 1, a steel ball 2, a valve core 3, a retaining sleeve 4, a filter cavity 5, a compression cavity 6, a connecting shaft 7, an external air intake channel 8, a valve sleeve 9, an inner Air intake channel 10, acrosome cavity 11.

[0022] The lower end of the valve body 1 is provided with a connecting shaft 7, and the connecting shaft 7 is provided with threads. At the same time, the working shaft of the centrifugal oil purification equipment connected with the present invention is also provided with threads. These two groups of threads cooperate with each other, so in the centrifugal When the working shaft of the oil purification equipment rotates, the entire gas ballast valve will also rotate with it.

[0023] The upper end of the valve body 1 is a cylinder, and it can also be set as other structures having the same function. The valve body 1 is provided with at le...

Abstract

The invention relates to a gas ballast valve which solves the problems of large occupied space and high cost of an original gas ballast valve. The novel gas ballast valve is provided with a valve body and a gas inlet channel; a top body is arranged in the gas inlet channel; a filter cavity is arranged on the gas inlet channel; the filter cavity divides the gas inlet channel into an outer gas inlet channel and an inner gas inlet channel; the outer and inner gas inlet channels are not in the same straight line; an included angle more than or equal to 0 degree and less than 90 degrees is formed between the outer gas inlet channel and the inner gas inlet channel; and a detachable spacer sleeve is arranged out of the filter cavity. The gas ballast valve can be widely applied to the field of centrifugal vacuum purification.

Description

technical field [0001] The invention relates to a valve part, in particular to a gas ballast valve with small occupied space and low cost. Background technique [0002] A gas ballast valve is a valve used in conjunction with a vacuum pump. When the vacuum pump is used to extract humid air, if the vacuum pump without gas ballast valve is used to extract this part of water vapor, the steam will be liquefied and dissolved in the oil, and the vacuum properties of the oil will deteriorate, thus reducing the pumping speed and vacuum degree of the pump. . [0003] In order to meet the requirement of extracting humid air without water vapor polluting the oil quality, a gas ballast valve can be installed on the vacuum pump. The principle is to put a certain amount of air in the compression process to increase the pressure of the mixed gas. The pressure of the mixed gas is The sum of the partial pressure of air and the partial pressure of water vapor, when the partial pressure of st...
