Description

A kind of negative pressure valve and there is its water dispenser
Technical field
The present invention relates to a kind of field of water fountain, is specifically a kind of negative pressure valve on water dispenser, and negative with this The water dispenser of pressure valve.
Background technology
Water dispenser has generally included two kinds of forms of water tank and cistern free, there is the usual no pressure in water source of water tank, it is therefore desirable to By being pressurized water supplying pump, booster pump short life, it is difficult to for commercial applications;Usually there is pressure at the water source of cistern free, can use general Water flowing water supplying pump, but due to needing to adjust flow, it is therefore desirable to extra flow control valve, check valve are set, and structure is multiple It is miscellaneous, it is of high cost.
The water dispenser of above two form, its water supply part can not be general, cause enterprise development difficulty big, development cost It is high.
The content of the invention
It is an object of the invention to overcome above-mentioned the shortcomings of the prior art, and a kind of negative pressure valve is provided and there is its Water dispenser, it can be common to water tank and cistern free form water dispenser uses, service life length, suitable for family expenses, commercial field Close, reduce enterprise development cost.
The object of the present invention is achieved like this:
A kind of negative pressure valve, including in water inlet end, valve chamber and the valve body of water outlet is axially arranged with, valve is equipped with the valve chamber Core, piston rod, the opening connected on the spool in being axially arranged with water outlet, during the piston rod is are movably equipped with spool Blank pipe, its one end are equipped with the water inlet connected with water inlet end, and other end is equipped with water outlet, and piston rod is slided in axial elasticity and set Put in spool;When the water inlet end produces negative pressure, piston rod slides axially to water outlet, water outlet and open communication, described When water inlet end recovers normal pressure, piston rod is resetted to water inlet end axial elasticity to be slided, and water outlet is disconnected with opening.
The water outlet is opened in the side wall of piston rod, and spool inner wall corresponds to the position where water outlet when piston rod resets Equipped with the plastic sealing water for closing water outlet.
The plastic sealing water both ends be equipped with piston rod against the first pilot seal circle.
The opening is in horn-like, and the opening diameter close to water outlet one end that is open is more than opening away from water outlet one end Opening diameter.
The spool is equipped with spool stage portion, and the shaft of the piston rod is equipped with piston rod step portion, spool step Resetting spring is equipped between portion and piston rod step portion.
Reset valve block is also sealedly connected between the piston rod step portion and valve body, resets valve block and valve body, spool, work The reseting cavity connected with ambient atmosphere is formed between stopper rod.
Corresponded in the valve body piston rod water inlet one end be equipped with piston rod against the second pilot seal circle.
The spool can be integrally formed in valve body, or is removably mounted in valve body.
The valve body is made of the first housing and the second housing, and water inlet end is integrally formed on the first housing, water outlet one It is body formed on the second housing, first housing and the second housing by welding, spiral cover nut, screw, snap connection fixation.
A kind of water dispenser, including foregoing negative pressure valve, the water inlet end of negative pressure valve are connected with water source, the water outlet of negative pressure valve according to It is secondary to be connected with pump, heater, discharging device
Present invention has the advantages that:
When negative pressure valve produces negative pressure in water outlet, the activity of its piston rod is opened, so as to fulfill the water supply of water dispenser, piston rod Opening amplitude is determined by negative pressure pressure, meets the use of adjustable water flow, and when negative pressure pressure disappears, negative pressure valve water outlet is extensive During multiple normal pressure, piston rod activity is closed, and is stopped supplying water to water dispenser, is played the role of shutting off, and potentially acts as check valve use.
Negative pressure valve coordinate conventional pump (water pump or air pump) become standard water supply component, can be suitable for have water tank and Cistern free form water dispenser uses, and negative pressure pressure is adjusted so as to fulfill adjusting water outlet flow by being realized to the pulse regulation of pump, Without additionally setting flow control valve, without check valve is set, service life length, suitable for family expenses, commercial applications, is manufactured into This is low, reduces enterprise development difficulty and development cost.
Brief description of the drawings
Fig. 1 is the structure diagram of one embodiment of the invention water dispenser.
Fig. 2 is one embodiment of the invention negative pressure valve reset state schematic diagram.
