Description

Salvo spring

Technical field

The utility model relates to a kind of fountain apparatus.

Background technology

In the prior art, a kind of fountain apparatus with explosion effect is arranged, it mainly includes the air accumulator of connecting with compressed air source, is connected with the air inlet of a magnetic valve on the air accumulator through pipeline, and the gas outlet of magnetic valve is connected with jet pipe, and the outlet of jet pipe upwards.This device is during work, and the spout of jet pipe is embedded under water, and water can enter in the jet pipe, and when magnetic valve was opened, the compressed air in the air accumulator from going out, sent sound, spray under water behind magnetic valve, jet pipe, can build view.Its weak point is: give vent to anger by magnetic valve moment, require the size of outlet passageway of magnetic valve very big, therefore, the overall dimensions of magnetic valve is very big; In addition, connect, make the overall dimensions of device also become greatly by pipeline, compact inadequately on the structure.

The utility model content

The purpose of this utility model provides a kind of salvo spring, makes its compact conformation, and the size of magnetic valve also can reduce significantly.

The purpose of this utility model is achieved in that salvo spring, comprise air accumulator, magnetic valve and jet pipe, air accumulator and compressed air source are connected, the outlet of jet pipe upwards is provided with, described air accumulator is provided with a cover body, mask body intracavity and air accumulator intracavity inter-connection, be fixed with air bag in the cover body, described air bag downside is connected with seal cover board, also be provided with the escape pipe of a U-shaped in the air accumulator, the mouth of pipe of escape pipe one end extend in the cover body and sealed cover plate covers, and the escape pipe other end is connected with described jet pipe, and the mouth of pipe of jet pipe stretches out outside the air accumulator; The import of described magnetic valve is connected on the air bag through pipeline, and atmosphere is connected in the outlet of magnetic valve, and the import of magnetic valve also links to each other with compressed air source.

During this device work, compressed air source replenishes compressed air in air accumulator, and compressed air also can charge into compressed air in air bag, make the air bag inside and outside air pressure balance, and air bag can rely on seal cover board to cover the mouth of pipe of gas outlet, and escape pipe can not be given vent to anger; When magnetic valve is opened, gas moment in the air bag releases, air pressure in the cover body is pushed air bag, seal cover board is risen abdicate the mouth of pipe upper space of escape pipe, mass air flow is gone out through jet pipe from escape pipe, because jet pipe is embedded under water, a large amount of gases can produce the gas explosion effect when going out, produce loud noise, can produce very big spray simultaneously; When closed electromagnetic valve, the equal air inlet of air bag and escape pipe, air bag is heaved, and makes seal cover board cover the escape pipe mouth of pipe, can build pressure in the air accumulator, for getting ready next time.Compared with prior art, the utility model compact conformation, the size of magnetic valve can be done very for a short time, and this device can be used to build the fountain view.

For guaranteeing air bag energy reliably working, described air bag top is provided with upper cover plate, and air bag is provided with back-moving spring between described upper cover plate and the seal cover board in upper cover plate is fixed on cover body.When the air bag internal and external pressure balance, can guarantee that by back-moving spring seal cover board can reliably be sealed on the mouth of pipe of escape pipe, after seal cover board rose, and the interior gas of tank body is discharged, back-moving spring can promote seal cover board rapidly and cover the escape pipe mouth of pipe.

Description of drawings

Fig. 1 is the utility model structural representation.

Wherein, 1 air accumulator, 2 escape pipes, 3 jet pipes, 4 back-moving springs, 5 upper cover plates, 6 cover bodies, 7 magnetic valves, 8 stop valves, 9 check valves, 10 air inlet pipe, 11 seal cover boards.

The specific embodiment

As shown in Figure 1, be salvo spring, comprise air accumulator 1, magnetic valve 7 and jet pipe 3, air accumulator 1 is connected through check valve 9, air inlet pipe 10 with compressed air source, the outlet of jet pipe 3 upwards is provided with, described air accumulator 1 is provided with a cover body 6, and cover body 6 inner chambers and air accumulator 1 intracavity inter-connection are fixed with air bag in the cover body 6, air bag top is provided with upper cover plate 5, air bag is in upper cover plate 5 is fixed on cover body 6, and described air bag downside is connected with seal cover board 11, is provided with back-moving spring 4 between upper cover plate 5 and the seal cover board 11; Also be provided with the escape pipe 2 of a U-shaped in the air accumulator 1, the mouth of pipe of escape pipe 2 one ends extend in the cover body 6 and sealed cover plate 11 covers, and escape pipe 2 other ends are connected with described jet pipe 3, and the mouth of pipe of jet pipe 3 stretches out outside the air accumulator 1; The import of described magnetic valve 7 is connected on the air bag through pipeline, and atmosphere is connected in the outlet of magnetic valve 7, and the import of magnetic valve 7 also links to each other with compressed air source through stop valve 8.

During work, compressed air source replenishes compressed air through check valve 9 in air accumulator 1, compressed air also can charge into compressed air through check valve 9 and stop valve 8 in air bag, make the air bag inside and outside air pressure balance, seal cover board 11 covers the mouth of pipe of gas outlet, and escape pipe 2 can not be given vent to anger; When magnetic valve 7 is opened, gas moment in the air bag releases to atmosphere, intracapsular pressure reduces, air pressure in cover body 6 is pushed down, and seal cover board 11 rises and abdicates the mouth of pipe upper space of escape pipe 2, and mass air flow is gone out through jet pipe 3 from escape pipe 2, because jet pipe 3 is embedded under water, a large amount of gases can produce the gas explosion effect when going out, and produce loud noise, can produce very big spray simultaneously; When magnetic valve 7 cuts out, air bag and escape pipe 2 equal air inlets, air bag is heaved, and makes seal cover board 11 cover escape pipe 2 mouths of pipe, can build pressure in the air accumulator 1, for getting ready next time.

This device is not limited to the foregoing description, and described stop valve 8 can also replace with choke valve; The bottom of air accumulator can also be provided with draining valve, so that the water emptying in the air accumulator that will bleed, tank base also can be provided with footing so that install and fix.
