Abstract

The utility model discloses a diaphragm switch valve, including the diaphragm valve body to and the cooperation sets up the vacuum pump of diaphragm valve body one side. Diaphragm switch valve can overcome that power consumption is big among the prior art, operation process is complicated and defect such as with high costs to realize the advantage that power consumption is little, operation process is simple and with low costs.

Description

A kind of force diaphragm switching valve

Technical field

The utility model relates to field of mechanical technique, particularly, relates to a kind of force diaphragm switching valve.

Background technique

General switch valve, needs according to vacuum principle, and using without in extraneous source of the gas, instrument bellows switch valve source of the gas used is pressurized air, and the power consumption of aerogenesis Air Compressor Equipment is higher, utilizes minipump, realizes control switch valve by obtaining start and stop to pump.

Realizing in process of the present utility model, inventor finds at least to exist in prior art that power consumption is large, operating process is complicated and high in cost of production defect.

Model utility content

The purpose of this utility model is, for the problems referred to above, proposes a kind of force diaphragm switching valve, to realize the advantage that power consumption is little, operating process is simple and cost is low.

For achieving the above object, the technical solution adopted in the utility model is: a kind of force diaphragm switching valve, comprises membrane valve body, and is equipped with the vacuum pump in described membrane valve body side.

Further, near described vacuum pump, offer suction port at the top of described membrane valve body, offer inlet opening in the bottom of described membrane valve body; Described suction port, is communicated to the top entry of vacuum pump by the first gas piping; The bottom outlet of described vacuum pump, is communicated to inlet opening by the second gas piping;

The described gas by membrane valve body upper chamber vacuumizes squeezes into membrane valve body lower chambers, realizes moving up and down of membrane valve body chamber, regulates the action of membrane valve body.

The force diaphragm switching valve of each embodiment of the utility model, owing to comprising membrane valve body, and is equipped with the vacuum pump in membrane valve body side; Thus the defect that in prior art, power consumption is large, operating process is complicated and cost is high can be overcome, to realize the advantage that power consumption is little, operating process is simple and cost is low.

Other features and advantages of the utility model will be set forth in the following description, and, partly become apparent from specification, or understand by implementing the utility model.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

Accompanying drawing explanation

Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, does not form restriction of the present utility model with embodiment one of the present utility model.In the accompanying drawings:

Fig. 1 is the structural representation of the utility model force diaphragm switching valve.

By reference to the accompanying drawings, in the utility model embodiment, reference character is as follows:

1-vacuum pump; 2-suction port; 3-inlet opening.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.

According to the utility model embodiment, as shown in Figure 1, a kind of force diaphragm switching valve is provided.

The force diaphragm switching valve of the present embodiment, comprises membrane valve body, and is equipped with the vacuum pump (as vacuum pump 1) in membrane valve body side.

In the above-described embodiments, near vacuum pump, offer suction port (as suction port 2) at the top of membrane valve body, offer inlet opening (as inlet opening 3) in the bottom of membrane valve body; Suction port, is communicated to the top entry of vacuum pump by the first gas piping; The bottom outlet of vacuum pump, is communicated to inlet opening by the second gas piping; The gas of membrane valve body upper chamber is vacuumized and squeezes into membrane valve body lower chambers, realize moving up and down of membrane valve body chamber, regulate the action of membrane valve body.

The technical solution of the utility model, does not need extraneous source of the gas, utilizes the gas in the upper and lower chamber of membrane valve to carry out switch, is vacuumized by the gas of upper chamber and squeeze into lower chambers, realize moving up and down, thus modulating valve action.

Last it is noted that the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although be described in detail the utility model with reference to previous embodiment, for a person skilled in the art, it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
