Logical, the air inlet port and exhaust port of the valve body are formed through perforation chamber, pass through between perforation chamber and the upper chamber
Second inside air flue is connected to, and is provided with Venturi tube component in the lumen therethrough room, the body base is provided with vacuum port, very
It eats dishes without rice or wine to be connected to by the second inside air flue and upper chamber with vacuum release holes.
The Venturi tube component includes Laval-cavity nozzle and expansion pipe, the gas of described Laval-cavity nozzle one end and muffler
Pipeline connector is connected, and the Laval-cavity nozzle other end is connected with expansion pipe.
There are two the first sealing element, the relief valve bottom is provided with the second sealing member for the relief valve side wall setting
Part.
Third sealing element is provided between the plug and valve body.
The vacuum release holes are set as four.
Compared with prior art, the present invention, which only passes through gas source all the way, can quickly control the generation and release of vacuum, reliably
Efficiently, can derivative form it is wider, especially release valve arrangement, dynamic-form and static form can be derived.Because its structure is simple, volume
Smaller, long service life, failure rate is low, easy to maintain, and can reduce the weight of mechanical arm to a certain extent.

Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
As Figure 1-Figure 4, energy-saving single channel jet type vacuum generator, including valve body 1 are set at the top of the valve body 1
It is equipped with upper chamber 2,1 ontology of valve body is equipped with the vacuum release holes 3 being connected to upper chamber 2 middle and lower part, 1 upper chamber of valve body
It is inside provided with relief valve 4, and 4 bottom of relief valve is fixed on 2 inner cavity bottom end of upper chamber by Helix Cylinder Compressible Spring 5, is formed
Single-acting valve arrangement is provided with plug 6 in the 4 top upper chamber of relief valve, sets in 4 right end valve body of relief valve, 1 side wall
It is equipped with the first inside air flue 7, the 1 exhaust port inner wall of valve body is bolted with muffler 8, the 1 air inlet port inner wall spiral shell of valve body
It is connected to gas path joint 9, is connected between the gas path joint 9 and upper chamber 2 by the first inside air flue 7, the air inlet of the valve body 1
Port and exhaust port are formed through perforation chamber 10, pass through the second inside air flue between the perforation chamber 10 and upper chamber 2
11 are connected to, and are provided with Venturi tube component 12 in the perforation chamber 10,1 bottom of valve body is provided with vacuum port 13, vacuum
