Embodiment Construction
[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0018] Such as Figure 1-Figure 4 As shown, the energy-saving single-channel jet vacuum generator includes a valve body 1, an upper chamber 2 is arranged on the top of the valve body 1, and a vacuum release valve communicating with the middle and lower part of the upper chamber 2 is provided on the body of the valve body 1. Hole 3, the upper chamber of the valve body 1 is provided with a release valve 4, and the bottom of the release valve 4 is fixed to the bottom of the inner cavity of the upper chamber 2 by a helical cylindrical compression spring 5, forming a single-acting valve structure. The release valve 4 A plug 6 is arranged in the upper chamber on the top, and a first internal air channel 7 is arranged in the side wall of the valve body 1 at the right end of the release valve 4, and a muffler 8 is screwed on the inner wall of the exha...

The invention relates to an energy-saving single channel jet type vacuum generator, and belongs to the technical field of vacuum generators. The energy -saving single channel jet type vacuum generatorincludes a valve body, an upper chamber, a vacuum releasing hole, a releasing valve, a spiral cylinder compression spring, a plug, a first internal airway, a silencer, an air channel connector, a communication chamber, a second internal airway, a Venturi tube assembly, a vacuum port, a Rafal nozzle, an expansion pipe, first sealing elements, second sealing elements and third sealing elements. According to the energy saving single channel jet type vacuum generator, vacuum generation and releasing can be quickly controlled only through a one-road air source, reliability and high efficiency areachieved, the derivable form is wide, and in particular, the releasing valve structure can be derived from a dynamic form and a static form; and the structure is simple, the volume is small, the service life is long, the failure rate is low, maintenance is convenient, and the weight of mechanical arms can be lowered to a certain extent.
Description
technical field [0001] The invention belongs to the technical field of vacuum generators, and in particular relates to an energy-saving single-channel jet vacuum generator. Background technique [0002] The jet vacuum generator is a new, efficient, clean, economical, and small vacuum component that uses a positive pressure air source to generate negative pressure, which makes it possible to use both positive and negative pressure in places where there is compressed air, or in a pneumatic system. It becomes very easy and convenient to obtain negative pressure in the pressure place. Vacuum generators are widely used in industrial automation in the fields of machinery, electronics, packaging, printing, plastics and robots. The traditional use of vacuum generators is to cooperate with suction cups to carry out various materials It is especially suitable for the adsorption and transportation of metal materials. In this type of application, a common feature is that the required en...
