Abstract
The utility model discloses a kind of self-sealing water jet air ejector, including mixing chamber, it is characterised in that: nozzle is equipped in the mixing chamber, the top of mixing chamber is equipped with intake chamber, and the lower section of mixing chamber is equipped with collapsible tube；The side of the mixing chamber is equipped with air inlet, is equipped with self sealing structure at the air inlet；The utility model air inlet connection condenser, if water jet air ejector damages, is unable to operate normally for vacuumizing, and the water in water jet air ejector can be prevented to be drawn back into condenser, and then guarantees condenser safety.
Description
Technical field
The utility model relates to water jet air ejector more particularly to a kind of self-sealing water jet air ejectors.
Background technique
Water jet air ejector is a a energy-conserving product for being directed to condenser vacuum and other equipment vacuums, is come from water-jet pump
The working water with certain pressure enter nozzle through water chamber, the pressure energy of pressure water is speed energy by nozzle, and water flow is high
Speed is projected from nozzle, makes to generate high vacuum in air suction chamber, is extracted vapour, the gas mixture in condenser out, is entered receive together
The draw, water velocity slow down, and pressure gradually rises, finally to be slightly above atmospheric pressure discharge collapsible tube.Water jet air ejector advantage
Very much, such as: suction capactity is strong, and safe bath amount is big, and motor wasted work is low, and the service life is long, suction internal efficiency do not influenced by runing time,
Inspection interval length etc.；But existing water jet air ejector, if there is problem, when being unable to operate normally, water jet air ejector is being pressed
In the case where power, water is easy to be drawn back into condenser, so that there are security risks for condenser.
Utility model content
The utility model solves the air inlet of water jet air ejector to solve water jet air ejector when being unable to operate normally
There is water and be drawn back into the problem in condenser, proposes a kind of self-sealing water jet air ejector.
The technical solution adopted in the utility model is as follows:
A kind of self-sealing water jet air ejector, including mixing chamber, it is characterised in that: nozzle, mixing are equipped in the mixing chamber
The top of room is equipped with intake chamber, and the lower section of mixing chamber is equipped with collapsible tube；The side of the mixing chamber is equipped with air inlet, the air inlet
Self sealing structure is equipped at mouthful.
Further, the self sealing structure is as follows:
Inlet port is equipped with guiding trestle, one end of the guiding trestle connection support shaft, and the support shaft is cased with spring,
The other end of the support shaft is equipped with sealing counter plate.
Further, the sealing counter plate is hinged on mixing-chamber inlet side, and support shaft is equipped with enlarging device.
Further, the other side of the mixing chamber is equipped with support.
Further, extension tube is equipped with below the collapsible tube.
Further, the support shaft is located at input end middle position.
The utility model has the following beneficial effects:
The utility model air inlet connects condenser, can not be normal if water jet air ejector damages for vacuumizing
Operation, can prevent the water in water jet air ejector to be drawn back into condenser, and then guarantee condenser trouble free service.
The utility model realizes the intracavitary reflux of water jet air ejector by self sealing structure, and structure is simple, also guarantees condenser
Vacuum degree.
Detailed description of the invention
Fig. 1 is utility model structure chart.
In figure: 1, support；2, intake chamber；3, air inlet；4, support shaft；5, guiding trestle；6, enlarging device；7, nozzle；8,
Seal counter plate；9, spring；10, collapsible tube.
Specific embodiment
The utility model is described further with reference to the accompanying drawing:
As shown in Figure 1, a kind of self-sealing water jet air ejector, including mixing chamber, it is characterised in that: it is equipped in the mixing chamber
Nozzle 7, the top of mixing chamber are equipped with intake chamber 2, and the lower section of mixing chamber is equipped with collapsible tube 10；The side of the mixing chamber be equipped with into
Port 3 is equipped with self sealing structure at the air inlet 3.
The self sealing structure is as follows:
Inlet port is equipped with guiding trestle 5, and the guiding trestle 5 connects one end of support shaft 4, and the support shaft 4 is cased with
Spring 9, the other end of the support shaft are equipped with sealing counter plate 8.
The sealing counter plate 8 is hinged on mixing-chamber inlet side, and support shaft 4 is equipped with enlarging device 6.
The other side of the mixing chamber is equipped with support 1.
Extension tube is equipped with below the collapsible tube 10.
The support shaft 4 is located at input end middle position.
Embodiment:
Water jet air ejector is negative pressure state in the cavity of water jet air ejector when carrying out flow jet work, the pressure the case where
Under, so that sealing counter plate 8 to left side Unscrew；It is negative pressure state at air inlet 3 when water jet air ejector stops working,
Under pressure effect, sealing counter plate 8 is only fitted in the inside cavities of water jet air ejector.And then condenser can be efficiently separated and penetrated
Water air ejector guarantees that the water in water jet air ejector will not flow back into condenser, so that condenser operates normally safely.
Above-described embodiment: sealing counter plate 8 under pressure, is rotated by suspending pin shaft on the cavity of water jet air ejector in midair,
And under guiding trestle 5,9 structure of enlarging device 6, support shaft 4 and spring, realizes to open and seal and close.
Above description is only a specific implementation of the present invention, but the protection scope of utility model is not limited to
This, anyone skilled in the art within the technical scope disclosed by the utility model, the variation that can readily occur in or is replaced
It changes, should all cover within the protection scope of utility model.
