Abstract

The utility model provides an overflow pipeline anti-siphon device for a normal-pressure gas-liquid separator of a water ring vacuum pump. The overflow pipeline anti-siphon device comprises a separator overflow pipeline and is characterized by being internally provided with pipes, wherein the separator overflow pipeline consisting of a top adapter of an inverted U-shaped pipe and an overflow pipe is internally provided with an anti-siphon pipe; the anti-siphon pipe and the separator overflow pipeline are combined to form the anti-siphon device; one end of the anti-siphon pipe is hermetically connected with the top adapter of the inverted U-shaped pipe, and the other end of the anti-siphon pipe is provided with an opening; the inner cavity of the anti-siphon pipe is communicated with the inner cavity of the top adapter; and the opening end of the anti-siphon pipe is provided with a protection elbow with a downward opening. The device has the following beneficial effects: the design concept and the structure are novel; one end of the arranged anti-siphon pipe is provided with the opening communicated with the atmosphere, and an air column is formed at a high point so as to obstruct waterflow; and the opening end of the anti-siphon pipe is provided with the protection elbow with the downward opening, so that the anti-siphon pipe is protected, and foreign matters are prevented from entering into the anti-siphon pipe.

Description

Water ring vaccum pump atmospheric gas liquid/gas separator overflow passage anti-siphon means

Technical field

The utility model belongs to the parts of water ring vaccum pump atmospheric gas liquid/gas separator, is specifically related to water ring vaccum pump atmospheric gas liquid/gas separator overflow passage anti-siphon means.This device is mainly used in the gas-liquid separator of water ring vaccum pump assembly cover.

Background technique

In the prior art, water ring vaccum pump atmospheric gas liquid/gas separator (hereinafter to be referred as separator) overflow passage has two kinds of forms:

The first as shown in Figure 3, the spill pipe inverted U pipe of separator design, device inner connecting tube 5 can play the effect of sealing gas, prevents that gas from overflowing from spill pipe 7.

Its deficiency is, because siphonage, liquid level in separator just begins overflow when arriving low liquid level line, and unnecessary working solution constantly overflows, and can't satisfy the water ring vaccum pump needed liquid level that works.

It two is as shown in Figure 4, and adapter is not set in the separator, begins overflow when liquid level in the separator rises paramount liquid level line, though can guarantee the normal liquid level of working solution in the separator.

Its deficiency is that in gas-liquid separator, the liquid after gas-liquid separation is subjected to gas shock, liquid level is not to keep static, but has some fluctuations, in case liquid level is during a little less than high liquid level line, then can cause gas to overflow from spill pipe 7, can't satisfy the requirement of sealing gas in the design.

The model utility content

Goal of the invention of the present utility model is to improve the structure of separator spill pipe, overcomes the defects of prior art.

Of the present utility model is to realize by following technical solution its goal of the invention:

Design a kind of water ring vaccum pump atmospheric gas liquid/gas separator overflow passage anti-siphon means, comprise the separator overflow passage, it is characterized in that at device inner connecting tube 5, in the separator overflow passage that the top adapter 6 of inverted U pipe and spill pipe 7 form anti-siphonage pipe 8 is set, described anti-siphonage pipe 8 constitutes anti-siphon means with the separator overflow passage.

Above-mentioned water ring vaccum pump atmospheric gas liquid/gas separator overflow passage anti-siphon means is characterized in that: described anti-siphonage pipe 8 one ends are sealedly connected on the top of inverted U pipe and take on 6, and the other end is set to uncovered;

Described anti-siphonage pipe 8 inner chambers and top are taken over 6 inner chambers and are connected.

Above-mentioned water ring vaccum pump atmospheric gas liquid/gas separator overflow passage anti-siphon means is characterized in that anti-siphonage pipe 8 open-mouth ends arrange downward opening protection elbow 9.

The beneficial effects of the utility model are:

1. mentality of designing and structure innovation, anti-siphonage pipe 8 one ends of setting are set to uncovered, communicate with atmosphere, form gas column at height point, cut off current.

2. anti-siphonage pipe 8 opening ends arrange protection elbow 9, and are opening down, and the anti-siphon of protection is taken over, and prevents that foreign matter from entering.
