Abstract
The invention discloses a hydraulic ejector, which comprises a body and a spraying nozzle, wherein the spraying nozzle is arranged on the end portion of the body, and mutually communicated medium channels are respectively arranged in the body and the spraying nozzle. The hydraulic ejector is characterized in that a pressure sensor is arranged on the inner wall of the spraying nozzle, and a pressure gauge connected with the pressure sensor is installed on the outer wall of the spraying nozzle. The hydraulic ejector can visually display hydraulic pressures.
Description
Technical field
The present invention relates to a kind of injector, relate in particular to a kind of hydraulic ejector.
Background technology
Hydraulic ejector be a kind of have vacuumize, important available energy conversion that condensation, draining are one and do not have mechanically operated mechanical device, be equipment important in the vacuum concentration systems.It is to utilize the current of certain pressure to lead to the nozzle ejection that symmetry is uniformly distributed with into certain gradient, is aggregated on the focus.Because it is very high to spray water velocity,, makes and produce vacuum and suction air and indirect steam in the injector so around it, form negative pressure; The indirect steam of suction directly contacts with spraying current, carries out heat exchange, and the steam of the overwhelming majority is condensed into water; A small amount of steam that is not condensed and incoagulable gas are also owing to the current with high velocity jet rub mutually; Mix and extruding, be excluded, make the higher vacuum of the indoor formation of device through diffuser pipe.Hydraulic ejector is used very extensive; Be mainly used in vacuum and vapo(u)rization system; Carrying out technologies such as vacuum is drawn water, vacuum evaporation, vacuum filtration, vacuum crystallization, drying, deodorization, is the equipment of sugaring, pharmacy, chemical industry, food, salt manufacturing, monosodium glutamate, milk, fermentation and some light industry, defense sector's widespread demand.
At present, existing hydraulic ejector can not show the hydraulic pressure of nozzle ejection in use intuitively, thereby its use is brought inconvenience.
Summary of the invention
Technical problem to be solved by this invention provides a kind of hydraulic ejector that can show hydraulic pressure intuitively.
For solving the problems of the technologies described above; The present invention provides a kind of hydraulic ejector; Comprise body and nozzle, said nozzle is installed in the end of said body, has the medium channel that is interconnected in said body and the said nozzle; On the inwall of said nozzle pressure sensor is installed, the Pressure gauge that is connected with said pressure sensor is installed on the outer wall of said nozzle.
The end of said body and said nozzle is provided with installation portion.
Offer installing hole on the said installation portion.
Compared with prior art, beneficial effect of the present invention is:
Because the inwall of hydraulic ejector nozzle of the present invention is provided with pressure sensor; So can know the hydraulic pressure that goes out from nozzle ejection through this pressure sensor; And can read hydraulic pressure intuitively through the Pressure gauge that is arranged on the nozzle outer wall; Therefore use more conveniently, hydraulic ejector of the present invention can show hydraulic pressure intuitively.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is explained further details
Fig. 1 is a structural representation of the present invention.
Among the figure: body 2, nozzle 4, pressure sensor 6, Pressure gauge 8.
The specific embodiment
As shown in Figure 1; Hydraulic ejector of the present invention mainly comprises the body 2 and the nozzle 4 that is arranged on main body 2 ends of injector, wherein has the medium channel that is interconnected in body 2 and the nozzle 4; Special feature of the present invention is: pressure sensor 6 is installed on the inwall of nozzle 4; This pressure sensor 6 is connected with the Pressure gauge 8 that is installed in nozzle 4 outer walls, during use, but the hydraulic pressure that pressure sensor 6 perception are ejected from nozzle 4; And can show hydraulic pressure intuitively, thereby brought convenience to use through Pressure gauge 8.
As shown in Figure 1, be respectively arranged with installation portion 5 in the end of body 2 and nozzle 4, offer installing hole 7 respectively on this installation portion 5.
In sum, the present invention can show hydraulic pressure intuitively.
The above is merely preferred embodiments of the present invention; Protection scope of the present invention is not exceeded with above-mentioned embodiment; As long as the equivalence that those of ordinary skills do according to disclosed content is modified or changed, all should include in the protection domain of putting down in writing in claims.
Claims (3)
