Description
Technical field
The invention belongs to the technical field of negative pressure of negative pressure fish jar, negative pressure science popularization device, negative pressure recreational facilities, and in particular to take out
The negative pressure generator of gas.
Background technology
The air-extractor of existing technical field of negative pressure is mainly divided to two classes：
1, vacuum pump has sliding vane rotary vacuum pump, oilless vacuum pump, diaphragm pump etc..
2, the patent No. 201510658706.1, patent name：" negative pressure in " the negative pressure fish jar of internal overflow vacuum pump less "
Generating means ".
Invention content
Purpose of the present invention is to " depression generator " pumping principle, the pumping form in background technology described in the 2nd article
The improvement of progress provides another negative pressure ventilation device, i.e. negative pressure generator.
The present invention adopts the technical scheme that solve above-mentioned technical problem：
A kind of negative pressure generator, including accept ontology, pagoda connector, nozzle, diffuser, locking nut；Its main feature is that：Institute
It states to accept and pagoda connector is set in the middle part of ontology, diffuser and nozzle is respectively set in both ends, accepts ontology and pagoda connector, diffusion
Pipe, nozzle are all threadedly coupled, and use sealing ring one, sealing ring two and sealing ring three at sealing successively；
Water inlet is arranged in one end of the nozzle；Connecting pin is arranged in water inlet outer wall；Setting is convex outside the other end of nozzle
Groove installation sealing ring three is arranged in Conic nozzle, inside setting jet pipe in the middle part of outer nozzle wall；
Recessed conical entrance is arranged in diffuser one end setting outlet, middle part setting trunnion, the other end, and the diffuser is logical
The threaded connection place that sealing ring two ensures to accept between ontology and diffuser is crossed to seal；
After the size for rotating diffuser fine tuning gap, fixed by locking nut with ontology is accepted, the model in the gap
Enclose is 0.5 to 2.5mm；
The diameter of the jet pipe is less than the diameter of trunnion；The line footpath of the sealing ring two is enough to adapt to the feelings ensureing sealing
Diffuser is rotated under condition finely tunes gap.
The taper of the male conical nozzle is no more than 90 °, the phase of the concave cone shape entrance taper and the male conical nozzle
It coincide.
It is provided with air flue on the pagoda connector, and installs sealing ring one additional；
The gap can be also made of loudspeaker face.
Compared with prior art, the present invention having the advantages that：
Since the present invention uses spray nozzle device and trunnion device, by screwing trunnion device to adjust air inlet gap, originally
The male conical nozzle of invention matches with recessed conical entrance, and the gap of the two is adjusted to very little, since the diameter of jet pipe is less than larynx
The diameter of pipe so that the flow sprayed from jet pipe fully enters trunnion, does not generate mixed flow in gap location so that the water of certain pressure
It flows to end there may be sufficiently large negative pressure, the present invention that different size trunnion, jet size are constituted is suitable for different negative pressure facilities
It applies.

Specific implementation mode
As shown in Figure 1, a kind of negative pressure generator, including accept ontology 2, pagoda connector 1, nozzle 6, diffuser 4, locking screw
Mother 3；Its main feature is that：2 middle part setting pagoda connector 1 of the undertaking ontology, diffuser 4 and nozzle 6 is respectively set in both ends, accepts this
Body 2 and pagoda connector 1, diffuser 4, nozzle 6 are all threadedly coupled, and use sealing ring 1, sealing ring two at sealing successively
4.3 and sealing ring 3 6.5；
Water inlet 6.4 is arranged in one end of the nozzle 6；Connecting pin 6.3 is arranged in water inlet outer wall；Outside the other end of nozzle 6
Male conical nozzle 6.1 is arranged in portion, and groove installation sealing ring 3 6.5 is arranged in setting jet pipe 6.2 in inside in the middle part of 6 outer wall of nozzle；
Recessed conical entrance 4.3, institute is arranged in 4 one end of diffuser setting outlet 4.1, middle part setting trunnion 4.2, the other end
Diffuser 4 is stated to seal by the threaded connection place that sealing ring 2 4.3 ensures to accept between ontology 2 and diffuser 4；
After rotating the size that diffuser 4 finely tunes gap 5, fixed by locking nut 3 with ontology 2 is accepted, the gap 5
Range be 0.5 to 2.5mm；
The diameter of the jet pipe 6.2 is less than the diameter of trunnion 4.2；The line footpath of the sealing ring 2 4.3 is enough to adapt to protecting
Diffuser 4, which is rotated, in the case of card sealing finely tunes gap 5.
