Abstract
The utility model discloses a manual/ power-driven ball type bidirectional vacuum generator which comprises a rotating shaft, a compressed air input assembly, a sealing member, an end cover, a pipe connector and a power-driven actuator, wherein a manual adjusting knob is installed on the power-driven actuator. The power-driven actuator comprises a body and a casing, wherein the body is a sphere, a rotating shaft key groove is arranged on the body, and a straight hole and a vacuum cavity are arranged in the body and communicated with each other. A vacuum nozzle is arranged on the body and communicated with the vacuum cavity, and the body is installed in the casing and connected with the rotating shaft. The manual/ power-driven ball type bidirectional vacuum generator achieves manual and power-driven control, can generate bidirectional vacuum, can adjust magnitude of the flow, can perform sealing closing of a vacuum pipeline, can generate flow of air which is four times as the flow of the input compressed air and can fully utilize the remaining energy of the compressed air which generates the vacuum.
Description
Technical field
The utility model relates to the pneumatic vacuum generator field of vacuum technique, relates in particular to a kind of hand/electronic ball-type bidirectional vacuum generator.
Background technique
Present pneumatic vacuum generator divides pneumatically controlled straight-through type or ecp straight-through type; Be by pressurized air through single-stage or multistage Lavalle expansion jet pipe and vacuum a kind of vacuum generating device, to be vacuum generating device form by shrinking earlier the Lavalle expansion jet pipe afterwards expanded, negative cavity, receiving tube etc. its structural principle.Air vent, exhaust port, vacuum hole are arranged.After the supply gas pressure of air vent was higher than certain value, jet pipe penetrated supersonic jet.Because the viscosity of gas, high-speed jet entrainment the gas in the negative cavity, make this chamber form very low degree of vacuum.The general character of said apparatus is can not change vacuum generation direction, can not change flow and can not in vacuum generator, carry out latus rectum and end.
The model utility content
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of hand/electronic ball-type bidirectional vacuum generator is provided.
The utility model for realizing the technological scheme that above-mentioned purpose adopted is: a kind of hand/electronic ball-type bidirectional vacuum generator, comprise rotatingshaft, pressurized air input assembly, Sealing, end cap, pipe connector and YE, and the manual adjustment knob is housed on the described YE; Rotatingshaft is equipped with in the bottom of said YE, comprises body and housing, and described body is a spheroid; Described body is provided with the rotating shaft keyway; Be provided with straight hole and vacuum chamber in the described body, and straight hole and vacuum chamber communicate, described body is provided with vacuum nozzle; Described vacuum nozzle communicates with vacuum chamber; Described body is contained in the housing and with rotatingshaft and is connected, and Sealing is equipped with in described body both sides, and described housing is fixedly connected with YE; Pressurized air input assembly, end cap are housed on the described housing, and described pipe connector is contained on housing, the end cap.
Described vacuum chamber is made up of bocca and big cone.
Described vacuum nozzle is around the circumference uniform distribution of body.
Described housing is connected through screw with YE.
The utility model can realize manually reaching electronic control; Can produce bidirectional vacuum, the size of flow rate adjustable, the sealing that can carry out vacuum pipe ends; Can produce and be four times in the compressed-air actuated conveying gas flow of input, can make full use of the compressed-air actuated dump energy that produces after the vacuum.

Wherein: 1, rotatingshaft 2, body 3, housing 4, pressurized air input assembly 5, Sealing 6, end cap 7, pipe connector 8, YE 9, manual adjustment knob 10, rotating shaft keyway 11, vacuum nozzle 12, straight hole 13, bocca 14, big cone.
Embodiment
Like Fig. 1-shown in Figure 6, a kind of hand/electronic ball-type bidirectional vacuum generator comprises rotatingshaft 1, body 2, housing 3, pressurized air input assembly 4, Sealing 5, end cap 6, pipe connector 7 and YE 8; On the described YE 8 manual adjustment knob 9 is housed, rotatingshaft 1 is equipped with in the bottom of said YE 8, and described body 2 is a spheroid; Described body 2 is provided with rotating shaft keyway 10; Be provided with straight hole 12 and vacuum chamber in the described body 2, and straight hole 12 communicates with vacuum chamber, described vacuum chamber is made up of bocca 13 and big cone 14; Described body 2 is provided with vacuum nozzle 11; Described vacuum nozzle 11 is around the circumference uniform distribution of body 2, and described vacuum nozzle 11 communicates with vacuum chamber, and described body 2 is contained in the housing 3 and with rotatingshaft 1 and is connected; Sealing 5 is equipped with in described body 2 both sides; Described housing 3 and YE 8 are connected through screw, and pressurized air input assembly 4, end cap 6 are housed on the described housing 3, and described pipe connector 7 is contained on housing 3, the end cap 6.
After supply gas pressure is higher than certain value; Through pressurized air input assembly 4; The pressurized air input action can produce vacuum in body 2, and rotate rotatingshaft 1 this moment, and body 2 axial directions are changed; Again because Sealing 5 has elastic packing property; The object that needs to carry is realized carrying under greater than the prerequisite of conveying capacity so all rotatable adjustment when no matter whether producing vacuum, the vacuum of generation and straight hole 12 inhaled airs and exhaust port dump energy air three acting in conjunction can make down, unsteady flow amount and ending, but but both also vertical transport of horizontal feed.
The above; Be merely the preferable embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or changes according to the technological scheme of the utility model and design thereof in the technical scope that the present invention discloses, and all should be encompassed within the protection domain of the utility model.
