Accompanying drawing explanation
Fig. 1 is pump automatic exhaust device generalized section.
Embodiment
Now by reference to the accompanying drawings this case is further described:
As shown in Figure 1, pump automatic exhaust device such as the taper piston 1 in Fig. 1 is arranged near the water outlet first half as the pump 3 in Fig. 1.Fluid pressure when using under normal circumstances in pump chamber can act on and move upward as taper piston hydraulic pressure cavity 4 inner and outer surface in Fig. 1 can promote taper piston, the relief opening in sealing automatic exhaust device.When numerically controlled intelligent electric pump is taking out as during hot water 5 in Fig. 1, pump chamber inside can produce a large amount of bubbles 6.Lengthen along with taking out the hot water time, the hot gas of air can be assembled in pump chamber inside.When in hot gas to pump chamber during certain pressure, gas occupies the area of water, because inner and outer air pressure is unbalance.The impeller of water pump is beaten less than water.The hydraulic pressure of pumping for water pump can reduce greatly.Thus taper piston can automatically from lower motion because conducting oneself with dignity or adding spring-loaded taper piston.Make gas can from relief opening 2 Exhaust Gas.Reduce the hot gas pressure of pump chamber inside, make water pump get back to again inside and outside air pressure balance state.
Pump automatic exhaust device, the water outlet of pump installs automatic exhaust device, automatic exhaust device comprises exhaust cylinder 7, taper piston, exhaust cylinder with pump the mouth of a river coordinate fix, exhaust cylinder bottom and water outlet inside are screw-thread fit, exhaust cylinder is higher than the ring part of part for setting to the concave of water outlet, and ring part is provided with relief opening; Taper piston, exhaust cylinder internal engagement is provided with tapered piston, and taper piston is stepped part higher than exhaust cylindrical portions, to ensure location when tapered piston is descending; It is the line part coordinated with ring part in the middle part of taper piston, gap is provided with as exhaust passage between line part and ring part, line part axial dimension is greater than ring part axial dimension, line part connects tapered portion, tapered portion diameter is first lower becomes large until leave slit-shaped with cylinder inner wall to become exhaust passage, be provided with the hydraulic pressure cavity emptied bottom taper piston, the position of hydraulic pressure cavity in piston is that taper is arranged, and adopts inside swedged tapered arrangement.The tapered portion of taper piston is connected with the second line part downwards, the second line part external diameter with exhaust bottom of cylinder minor diameter fit and leave gap as exhaust passage, the second line part realizes the upper and lower operation leading role of taper piston.On ring part, relief opening is exhaust hole.
In a further embodiment, taper piston is connected with spring to the direction that pump chamber is descending, and spring setting pressure is exhaust pressure, and when pump chamber pressure is greater than spring setting pressure, taper piston is withstood, and spring is stretched, and tapered portion seals exhaust passage; When pump chamber pressure is less than spring setting pressure, tapering spring is by springs return, and exhaust passage conducting between line part and exhaust cylinder, exhaust passage is communicated with exhaust hole and realizes exhaust.
In a further embodiment, on ring part, exhaust hole is annular connectivity structure, and the relief opening namely on ring part is exhaust annulate lamella.
In a further embodiment, pump is water pump, numerically controlled intelligent pump.
Principle of device: utilize taper piston to seal, when the position of the impeller contact water in pump chamber is occupied by gas, can not normal pumping, pump chamber internal pressure declines, pressure drop to can not by packed-piston deadweight and spring adjustment popping pressure time, leakage port seal failure, reaches and automatically opens exhaust, and this device is arranged on pump housing water outlet higher than water intake height and position.
Finally should be noted that: above embodiment is only in order to illustrate that technological scheme is not intended to limit; Although be described in detail with reference to preferred embodiment; those of ordinary skill in the field are to be understood that: still can modify to embodiment or carry out equivalent replacement to portion of techniques feature and do not depart from the spirit of scheme, it all should be encompassed in the middle of the technological scheme scope of this case request protection.
