The Drop-proof valve of liquid packing machine of the present utility model is compared with device before, the actuating device that not only can save cock, accomplished simple in structure, save cost, and can effectively overcome the weeping of the valve of liquid packing machine before and can accomplish accurate metering.
Description of drawings
Fig. 1 is the constructional drawing of the valve of prior art.
Fig. 2 is the constructional drawing of the Drop-proof valve of liquid packing machine of the present utility model.
The specific embodiment
Followingly the specific embodiment of the present utility model is elaborated with reference to accompanying drawing.
As shown in Figure 2, the Drop-proof valve of liquid packing machine of the present utility model is made of valve body 1 and plunger pump 2 two parts, its plunger pump 2 is made of plunger 21, the pump housing 22, plunger rod 23, plunger 21 can horizontally slip along the inner chamber of the pump housing 22, between the plunger 21 and the pump housing 22, establish seal ring, wherein, described valve body 1 comprises: inlet 17, first Metal Ball 15, second Metal Ball 16, first passage 11, second channel 12, liquid outlet 18; Liquid outlet 18 is connected with first passage 11, this first passage 11 is connected with second channel 12 by first valve opening 13, the internal diameter of first passage 11 is slightly larger than the internal diameter of first valve opening 13, the internal diameter that the external diameter of above-mentioned first Metal Ball 15 is slightly less than first passage 11 is slightly larger than the internal diameter of first valve opening 13, and this first Metal Ball 15 places between this first passage 11 and this first valve opening 13; Inlet 17 is connected with second channel 12 by second valve opening 14, the internal diameter of second valve opening 14 is slightly less than the internal diameter of second channel 12, the internal diameter that the external diameter of second Metal Ball 16 is slightly larger than this second valve opening 14 is slightly less than the internal diameter of this second channel 12, this second Metal Ball 16 places between the second channel 12 and second valve opening 14, the intracavity inter-connection of this second channel 12 and the above-mentioned pump housing 22; On above-mentioned first passage 11 and above-mentioned second channel 12, establish seal cover cap respectively.
In addition, inlet 17 and liquid outlet 18 are connected with feed tube 41 and drain pipe 31 by joint 17 ' and 18 ' respectively.
Between the described plunger and the described pump housing, establish 2～4 road seal rings.
Principle of work: when plunger 21 moves right by plunger rod 23 under the driving of plunger pump 22, the volume of the left part 24 of the pump housing 22 inner chambers changes from small to big, pressure reduction appears, at this moment, second Metal Ball 16 in the valve body is backed down by liquid, liquid enters the left part 24 of second channel 12 and the pump housing 22 inner chambers, simultaneously, because the power of 15 1 resorptions of first Metal Ball is given in the pressure differential effect, first Metal Ball 15 is pressed on first valve opening 13, and first valve opening 13 is closed, because first passage 11 does not communicate with second channel 12, so liquid can only enter the left part 24 of second channel 12 and the pump housing 24 inner chambers, this is the imbibition process.When being moved to the left by plunger rod 23 under the driving of plunger 21 at actuating device, the volume of the left part 24 of the pump housing 22 inner chambers from large to small, liquid backs down first Metal Ball, 15 flow of liquid and crosses first valve opening 13 and enter first passage 11 to liquid outlet 17; Simultaneously, liquid is given 16 1 pressure of second Metal Ball, and second Metal Ball 16 is pressed on second valve opening 14, and second valve opening 14 is closed, and then liquid flows out from liquid outlet 17.In next working cycle, plunger rod 23 moves right moment, gives 15 1 resorption power of first Metal Ball, owing to first Metal Ball 15, first passage 11, liquid outlet 18 communicate, promptly give a resorption power of liquid at liquid outlet 18 places, the water clock of liquid when so just having prevented fluid.
Establish seal cover cap 19 respectively on above-mentioned first passage 11 and above-mentioned second channel 12, so that first and second Metal Ball is placed in this first passage and the second channel, seal cover cap 19 is by being bolted on the valve body 1.
As seen, the Drop-proof valve of liquid packing machine of the present utility model has effectively overcome the weeping of the valve of liquid packing machine in the past.
