Description

Hand pump valve pipe

The utility model relates to a kind of improved conveying liquid hand pump valve tube, is specially adapted to the application in poisonous, the inflammable liquid drainage siphon.

The device of present manual feed liquid is shaking type, epithelium formula and reciprocating pump etc. normally, its volume is big, cost is high, carry inconvenience, and can't utilize difference of liquid level to carry out siphon, when the need siphon, rubber balloon commonly used is sucked the catheter drainage siphon in the laboratory, carries out the siphon oil transportation after driver's mouthful suction pipe drainage then commonly used, not only inconvenient, unhygienic but also dangerous, and more can't carry out flow control.

The utility model purpose is that flow is big, and is simple to operate for suction, outstanding phase of force feed are that siphon transfusion provides a kind of volume little, the low and random novel practical device of control flow rate of cost.

Finish method of the present utility model: be combined into one by a hand pump and a flow control valve.This hand pump can be a bellowspump, is the pump housing or sleeve pump with the bellows, is piston rod and apocenosis passage with the inner sleeve, and outer sleeve is a cylinder body, and valve block formula liquid discharging valve is equipped with in piston central authorities, and the inner sleeve internal diameter should be greater than the feed liquor catheter diameter.The characteristics of two kinds of pumps of this equivalence are the abilities with stronger suction and force feed liquid, and have less flow resistance and bigger flow, and flowing through of pump is simple and direct.When the end pressure that becomes a mandarin is slightly larger than out the stream end, liquid just can be from the end free stream that becomes a mandarin to going out the stream end, especially as in flowing through one section conduit, therefore be suitable for the siphon transfusion especially, liquid discharging valve end owing to flow control valve and pump links again, valve apertures equates that with the internal diameter of feed liquor conduit valve opening and pump are positioned on the same axis, so can arbitrarily utilize valve to come control flow rate as required.

Below in conjunction with accompanying drawing the present invention is further described.

23 valve gaps, 24 packing rings, 25 valve handles.

Inlet hole is arranged with reference to Fig. 2 end that becomes a mandarin on 1, screw air inlet bolt 2 and can seal this hole.The end 1 that becomes a mandarin is connected with outer sleeve 3 rib-loops, and there is position limit cycle 20 inner sleeve 4 ends, and inner sleeve and outer sleeve are movingly, a pump housing motion guide position-limiting action.Bellows 5 is made of soft macromolecular material, its internal diameter is greater than the internal diameter of feed liquor conduit, two ends are equipped with that the valve block formula is advanced, liquid discharging valve, bellows 5 is positioned among the inner sleeve 4, one end of bellows 5 is connected with the end that becomes a mandarin by chucking circle 6 and accompanies feed liquor valve block 7 and seal ring 8 formation feed liquor valves, the other end utilizes plate washer circle 9, and lining 10 is fixed on the step ring of inner sleeve inwall, accompanies discharge opeing valve block 21 and seal ring (two) 22 formation liquid discharging valves between plate washer circle and lining.Inner sleeve is connected with valve cavity 11 rib-loops, and it is free to rotate to be with a cover adapter ring 12 between inner sleeve 4 outer wall step rings and the valve cavity end face, has bull Daluo to cooperate with outer rib-loop on the outer sleeve 3 distolateral outer walls apart from interior rib-loop in the circle.The opposite side of valve cavity 11 holds 13 rib-loops to be connected with going out stream, by jam pot cover circle 14 valve body 15 sealings is positioned in the valve cavity, makes the valve body rotation by wrench 16 and valve shaft 17.

With reference to the sleeve pump of Fig. 3 and bellowspump equivalence, the end 1 that becomes a mandarin is connected with outer sleeve 3 rib-loops and accompanies feed liquor valve block 7 and seal ring 8 formation feed liquor valves.Soft rubber piston ring 19 is housed on the piston 18, and there is a valve opening in piston central authorities, and piston is connected with inner sleeve 4 rib-loops and accompanies discharge opeing valve block 21 and seal ring (two) 22 and constitutes liquid discharging valves.Outer sleeve 3 is as cylinder body and to piston and inner sleeve 4 moved guiding and position-limiting action, and inner sleeve 4 is as piston rod and apocenosis passage, and its other end then is connected with valve cavity 11 with cover adapter ring 12.

The internal diameter of bellows or piston inner sleeve is greater than the internal diameter of feed liquor conduit, and the aperture of combination valve and flow control valve equates with the internal diameter of feed liquor conduit at least.Advance, the discharge opeing valve block adopts that matter is thin, intensity is high, the high molecular film material of good springiness, it is shaped as valve gap 23 is one for 24 groups with packing ring, is connected by valve handle 25, the aperture of combination valve equates with the feed liquor catheter diameter at least.Can rely on natural elasticity entirely to be attached on the end face of valve opening when valve block does not stress, can bear higher backpressure, and when being subjected to less positive pressure, just can produce bigger deflection degree, make reflux valve obtain bigger open degree.

The working principle of hand pump valve tube is as follows: load onto the feed liquor conduit and insert in the source container at the end 1 that becomes a mandarin, load onto draining pipe or suitable discharge spout facing to the purpose container going out stream end 13, screw air inlet bolt 2, open flow control valve with wrench 16.Draw back pump valve Guan Erduan and make pump housing volume become big, this moment, the feed liquor valve block was opening state, and the discharge opeing valve block is the state of closing, simultaneously from going into conduit inspiration gas or liquid.Pushing the pump valve Guan Erduan compression pump housing then diminishes volume to close feed liquor valve block 7, open discharge opeing valve block 21 gas in the pump or liquid are pressed to draining pipe by valve body 15.Repeatable operation just can be transported to the liquid in the source container in the purpose container and go.When the pressure of liquid in the feed liquor conduit during greater than draining pipe, feed liquor valve block 7 and discharge opeing valve block 21 are opening state simultaneously, and liquid just can be from end 1 spontaneous current that becomes a mandarin to going out stream end 13, especially as flowing through one section conduit.Therefore when the source container liquid level is higher than the purpose tank fill level, in case with just can relying on siphonage to infuse after the hand pump drainage, and can interrupt or regulate flow by the angle of yaw of wrench 16 adjustment valve bodies 15.After suction finishes, can unscrew air inlet bolt 2 and bleed off residual liquid in the feed liquor conduit.During air pump inoperative, available cover adapter ring 12 screws outer sleeve, and two movable ends are fixed as one.

The parts of hand pump valve tube all can adopt injection moulding processing, and valve block can be die-cut.Cost is low, volume is little, avirulent, corrosion-resistant, the pump valve pipe of different size can be used in various occasions, as extract the can that is used for drinks, light oil, harmful liquid in reagent, the food chemical industry in the laboratory, open-air oiling of driver and exploration efforts at environmental protection person carry out the water quality sampling of different water layers in limber, well, korneforos.
