Abstract

The utility model provides a vacuum generator. A vacuum switch is arranged on the vacuum generator and communicated with a vacuum orifice on the vacuum generator; a pressure indicating meter and a positive pressure safety valve are arranged on the vacuum generator; and two ends of the pressure indicating meter are respectively connected with the vacuum generator and the positive pressure safety valve. The vacuum generator has the advantages of small size, high reliability, corrosion resistance, low noise and the like and is maintenance-free, the internal pressure of the vacuum generator can be remotely monitored by using the vacuum switch, and the opening and closing of an air inlet can be controlled by adoption of the vacuum switch; and moreover, pressure display and safety protection can be realized by using the pressure indicating meter and the positive pressure safety valve, and data indication and verification of the working state of the safety valve can be realized by matching the pressure indicating meter and the positive pressure safety valve.

Description

Vacuum generator
Technical field
The utility model relates to a kind of vacuum generating device, especially a kind of vacuum generator.
Background technique
Vacuum generator is to carry out work according to the Laval nozzle principle; Utilize jet pipe high velocity jet pressurized air; In the jet flow that nozzle exit forms, generation is entrainmented mobile, under the effect of entrainmenting; Make the nozzle exit ambient air constantly walked, the pressure in the adsorbent chamber is reduced to below the barometric pressure to form the certain vacuum degree by suction.Vacuum generator has efficiently, cleans, economic advantage, can in airtight relatively environment, use, and can in tens seconds to tens seconds time, will reduce to negative pressure fast than large-volume receptacle.
Yet in existing vacuum generator, it generally is that mechanical structure through valve etc. realizes that its shortcoming is to realize remote monitoring that its pressure is regulated.
Summary of the invention
To the deficiency of above-mentioned technology, the utility model provides a kind of vacuum generator that can carry out remote monitoring to the pressure of vacuum generator.
Be to realize above-mentioned purpose, the utility model provides a kind of vacuum generator, on said vacuum generator, vacuum port is installed, and vacuum switch also is installed on said vacuum generator, and said vacuum switch is connected with vacuum orifice on the said vacuum generator.
Pressure indicator and malleation safety valve also are installed on said vacuum generator, and the two ends of said pressure indicator are connected with said vacuum generator and said malleation safety valve respectively.
Said pressure indicator and said vacuum port are in parallel.
Said pressure indicator, said vacuum port, relief opening and ecp suction valve are installed in the bottom of said vacuum generator.
Said vacuum switch is installed in the top of said vacuum generator.
Compared with prior art, the utlity model has following advantage:
The utlity model has volume compact, non-maintaining, advantage such as reliability is high, corrosion-resistant and noise is low; Can realize the vacuum generator pressure inside is carried out remote monitoring through vacuum switch, therefore can also control the open and close of suction port through introducing vacuum switch; In addition, can also realize pressure-display and safety protection, can realize data indications and checking after the two matches the safety valve working state through pressure indicator and malleation safety valve.
Description of drawings
Fig. 1 is the structural drawing of the utility model;
Fig. 2 is the schematic diagram of Fig. 1.
Main symbol description is following:
1-ecp suction valve 2-vacuum switch
3-vacuum generator 4-relief opening
5-vacuum port 6-pressure indicator
7-malleation safety valve
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Like Fig. 1 and shown in Figure 2, vacuum switch 2, vacuum port 5, pressure indicator 6, malleation safety valve 7, relief opening 4 and ecp suction valve 1 are installed on vacuum generator 3.Wherein, vacuum switch 2 is installed in the top of vacuum generator 3 and is connected with vacuum orifice on the vacuum generator 3, and pressure indicator 6, vacuum port 5, relief opening 4 and ecp suction valve 1 are installed in the bottom of vacuum generator 3.Pressure indicator 6 is in parallel with vacuum port 5; Its two ends are connected with vacuum generator 3 and malleation safety valve 7 respectively; Pressure indicator 6 is in series with malleation safety valve 7; But, thereby can make judgement rapidly when being convenient to break down in system through pressure indicator and malleation safety valve manual observation systematic parameter.
The utility model is the main body with the vacuum generator housing, on vacuum orifice, is equipped with vacuum switch, provides signal to cut off the compressed-air actuated supply of suction port when reaching setting value final vacuum switch.Pressure indicator is with parallelly connected with vacuum port again after one-way valve is connected, with indication negative pressure pressure and press one-way valve setting pressure protective system.
The utility model is provided with the ecp suction valve at the corresponding interface place, and carries out the air inlet action according to programming instruction, and pressurized air and sealed volume and interior air are discharged from relief opening.Feedback process after the degree of vacuum of vacuum port reaches the vacuum switch setting value, programming instruction control ecp suction valve cuts out, and can read system pressure value and control system maximum vacuum through pressure indicator and the manual work of malleation safety valve.
The above is merely the preferred embodiment of the utility model, and is in order to restriction the utility model, not all within the spirit and principle of the utility model, any modification of being done, is equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
