Embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning Same or similar element is represented to same or similar label eventually or there is the element of same or like function.Below by ginseng The accompanying drawing description examined shows that embodiment is exemplary, is only used for explaining the utility model, and it is not intended that new to this practicality The limitation of type.Further illustrate below in conjunction with the accompanying drawings.

As shown in figs 1 to 6, a kind of full-automatic valve for pressure air air accumulator condensate, including housing 8, water inlet pipe 18th, outlet pipe 37, liquid-level switch, circuit board 14, filter 7 and electrical ball valve 20.

Specifically：

The square profile of housing 8, centre are machined with circular hole, and the lower part of circular hole forms valve pocket.The upper end of chamber valve is upper end Lid 36, lower end are bottom end cover 2.Upper end cover 36 is a cake shape, is machined with annular groove and step on the face of cylinder, is pressed O in annular groove Shape circle seals.They are installed along with the circular hole upper end of housing 8, are fixed, are used in combination using the step on upper end cover 36 and spring collar Phenolic resin curing seals.Bottom end cover 2 is fixed on the lower end of housing 8 by screw 1, and sealing ring 3 is used between bottom end cover 2 and housing 8 Sealing, is easily installed, is also convenient for detachable maintaining.

The upper end of circular hole assumes diamond in shape, rhombus wedge angle position is drilled with two holes substantially in diagonally plane is processed into top view Heating rod 21 and thermistor (not shown) are installed respectively, as shown in figure 3, being installed at installation heating rod 21 for heating rod in hole Hole 22, heating rod 21 are connected by heating rod wire 9 with circuit board 14.Thermistor is connected to electricity by thermal resistor wire 15 Road plate 14.Thermistor is used for the temperature for measuring self-draining arrangement, and when temperature is less than 0 DEG C, heating rod 21 is begun to warm up, when Heating rod 21 stops heating when temperature is higher than design temperature.

The side of housing 8 is provided with upward water inlet pipe 18 and downward outlet pipe 37, and the lower section of outlet pipe 37 is provided with electricity Dynamic ball valve 20.Observation window 19 is installed among water inlet pipe 18 and outlet pipe 37, for observing liquid level.

In housing 8（In valve pocket）One liquid-level switch is set, has two ball floats, the respectively He of upper floating ball 6 on liquid-level switch Lower ball float 4, limited location snap ring 5 is provided between upper and lower two ball floats.Two ball floats are respectively used to sense upper water level and lower water level.When Upper floating ball 6 sense water to upper water level when illustrate that water is full, can discharge water.Instantly ball float 4 illustrates that water has been in after resetting Lower water level, electrical ball valve 20 can close.Be covered with a filter 7 outside liquid-level switch, filter 7 be by it is stainless steel stretched into Barreled is intensive in the range of 180 ° on barrel circumference to rush micro hole（Filter opening）To play a part of impurity screening.In the range of another 180 ° Not punching, the air inlet of this part of face water inlet pipe 18 and the venthole of outlet pipe 37, prevent high velocity air from pouring impurity Filter 7.

In addition, there is a space in housing 8, more than end cap, for mounting circuit boards 14, circuit board 14 is the control of the present apparatus Part processed, circuit board 14 is installed screwed hole 23 by screw and circuit board and is fixed on housing 8, between circuit board 14 and housing 8 Leak is prevented with PUR sealing.

In the utility model, so-called " not punching ", " not having perforate " refer to filter 7 and do not have any hole in the side tube-wall Gap, the side tube-wall will separate completely inside and outside barrel, i.e., water can not pass through from the side tube-wall.

Foregoing liquid-level switch and electrical ball valve 20 are connected with circuit board 14.Foregoing upper floating ball 6 is led by liquid level upper switch Line 10 is connected with circuit board 14, and the lower ball float 4 is connected by liquid level lower switch wire 12 with the circuit board 14.

PVC panels 13 are printed in the upper paste of circuit board 14, and transparent window is provided with PVC panels 13, are easy to digital in observation Pipe, LED, wherein LED include draining indicator lamp 31, temperature indicator 32, burner on light 34 and anhydrous indicator lamp 35.Number Code pipe is for digitron display screen 33.There are seven projections on PVC panels 13, respectively seven buttons on corresponding circuits plate 14.Seven Individual button be respectively manual drainage button 24, timing drainage button 25, heating button 26, set button 27, subtract button 28, plus by Key 29 and saving button 30.Seven buttons cover all operationss function button, and in the absence of composite-key, operator need not remember Operation can conveniently be completed by recalling the operating method of complexity, using simple.

Power line 11（Electric power incoming line）Plug screw 16 with holes, plug screw 16 are installed by two holes respectively with the outlet of electrical ball valve 20 Endoporus rounding, prevents secant.Specifically, the side on housing 8 close to electrical ball valve 20 is perforated provided with the wire 17 of electrical ball valve 20, The perforation of the wire 17 of electrical ball valve 20 is provided with plug screw 16, and electrical ball valve 20 passes through the wire 17 of electrical ball valve 20 and the phase of circuit board 14 Even, the wire 17 of electrical ball valve 20 is perforated and plug screw 16 through the wire 17 of electrical ball valve 20.

The wire hole of electrical ball valve 20 is designed in side with electrical ball valve 20, easy for installation.

Housing 8 uses aluminum alloy material, non-corrosive, long lifespan, and heat conduction is good.

Power supply uses three plugs, and aluminum shell is grounded, and ensures the safety of operator.

The present apparatus in water level on water level reaches, open by electrical ball valve 20, starts draining, when water level is in lowest water level When, the lower ball float 4 of liquid-level switch declines, and lower water level switch resets, and electrical ball valve 20 is closed.Auto-drainage process is completed.

Operator can as needed can with manual drainage, press manual drainage button can draining, then by stop.

Full-automatic valve of the present utility model reached be not easy to block up, fault rate is low, easy to operate, confined gas is good and saves The advantages of pressure air.

While there has been shown and described that embodiment of the present utility model, it will be understood by those skilled in the art that： These embodiments can be carried out with a variety of changes, modification in the case where not departing from principle and objective of the present utility model, replaced And modification, the scope of the utility model are limited by claim and its equivalent.
