Abstract
The utility model relates to a snore piece liquid sampling unit which is composed of an air bag, and a liquid taking pipe of liquid suction and drainage control volume. The utility model is characterized in that the air bag is provided with a single-way air exhaust valve, the liquid suction and drainage control volume is a hollow rod shape control volume, and an air exhaust valve and an air intake valve is arranged on the liquid suction and drainage control volume. When the utility model is used, the air exhaust valve or the air intake valve is kneaded and squeezed, and the liquid suction or drainage quantity can be controlled. The utility model has the advantages of convenient operation, accurate liquid suction or drainage quantity, and rapid liquid suction or drainage. The utility model can be used for the quantitative chemical analysis in the field of agriculture, iatrology, biology, metallurgy, and geology.
Description
The utility model relates to a kind of liquid getting device that is specially adapted to quantitative suction amount in the analytical chemistry.
At present, the operation measure of quantitative liquid getting is normally inhaled with ear washing bulb or with mouth and is cooperated the liquid flowing tube draw solution in the analytical chemistry field, and its drawback is obvious, and promptly holding the liquor amount, to be difficult for Be Controlled accurate, causes the pollution of solution and extremely unhygienic easily.Chinese patent 86209521 discloses a kind of " directed location siphon device ", and its device top vent connects with sebific duct, block up in one this sebific duct of unidirectional venting ball a glass bead is arranged, when needing exhaust, the pinching venting ball is discharged air and is formed negative pressure of vacuum, the sebific duct at pinching glass bead place makes liquid suck along device then, the deficiency that this device exists is, when sebific duct can not keep vertical shape, can produce extruding to the sebific duct of bottom and influence the accuracy of liquid along the dosage of device suction, if the sebific duct wall is too thick, can cause the pinching difficulty, in addition, this device can not quantitatively discharge, thereby is used for cooperating suction pipe to get liquid just being restricted.
The purpose of this utility model is to provide that a kind of to get liquid easy and simple to handle, once accurately quantitative liquid getting and quantitatively the suction pipe liquid getting device of discharging.
Above-mentioned purpose of the present utility model is to realize by such structure, and promptly it is by air bag, inhales, the discharge opeing control volume, and liquid flowing tube constitutes, and it is characterized in that being equipped with on the air bag one-way exhaust valve, the air intake opening of air bag with advance, discharge opeing control volume one end is connected; Advance, the discharge opeing control volume is the rhabodoid of hollow, which is provided with vent valve and gas admittance valve, wherein vent valve is by type of tamper evidence, is positioned at that the type of tamper evidence both sides are communicated with the body of rod and the inlet and outlet hole of corresponding distribution, makes the airtight resilient sleeve formation in inlet and outlet hole on the body of rod; Gas admittance valve is by the hollow type of tamper evidence, the air admission hole that is communicated with the body of rod, and the air inlet duct in the rhabodoid outside, and be enclosed within the airtight resilient sleeve of air admission hole is constituted; Another termination hollow rubber plug of rhabodoid is connected with liquid flowing tube by it.
Said structure of the present utility model can further specify by accompanying drawing:
Accompanying drawing is a structure cut-away view of the present utility model.
Referring to accompanying drawing: check valve body (1), lateral pin (2), rubber core (3) is formed the top that an one-way exhaust valve is installed a rubber pneumatic bag body (4), and wherein lateral pin (2) breaks away from valve body in order to stop rubber core (3).The shaft-like of air intake opening elasticity expanded joint one hollow of the bottom of rubber pneumatic bag advances, discharge opeing control volume (5), but this rhabodoid hand stainless steel, organic glass or duroplasts are made, its epimere is provided with by type of tamper evidence (9), advance, vent port (8), the vent valve that rubber sleeve (6) constitutes, wherein type of tamper evidence (9) is stopped up the hollow channel in the rhabodoid, and form the boss of a ring-type on the surface of the body of rod, advance, the both sides that vent port (8) is positioned at boss respectively have 1～4, be corresponding branch, under the situation of cover rubber sleeve, the hole of type of tamper evidence boss both sides is the state of not conducting, is provided with by type of tamper evidence (11) at the hypomere of rhabodoid, air admission hole (8), the gas admittance valve that air inlet duct (10) and elastic caoutchouc cover (6) constitute, wherein type of tamper evidence (11) is a ducted body, its outside forms an annular boss on the surface of rhabodoid (5), air admission hole is positioned at the downside of boss, air inlet duct (10) is not communicated with rhabodoid, and it is corresponding distribution with air admission hole (8), generally respectively has 1～4.When rubber sleeve (6) when being enclosed within rhabodoid, blockage body (11) makes air inlet duct and air admission hole be the state of not conducting, and air inlet duct is communicated with atmosphere.The lower end of rhabodoid and hollow rubber plug (7) elasticity expanded joint are with the liquid flowing tube expanded joint of the quantitative scale lower end at rubber plug.
Quantitative liquid getting method of the present utility model is such: at first pinching rubber pneumatic bag (4) is extruded air, at this moment, because last vent valve is in closed condition, air bag is shunk and the generation negative pressure, and is not communicated with liquid flowing tube.The liquid flowing tube lower end is inserted in the solution, the rubber sleeve on the pinching vent valve (6) makes inlet and outlet hole (8) connection at type of tamper evidence (9) two ends and makes negative pressure enter liquid flowing tube again, and under the effect of negative pressure, liquid is inhaled into; When liquid level rises to required scale, stop the pinching vent valve, solution just stops to be inhaled into.If need emit the solution in the suction pipe, the pinching gas admittance valve makes atmosphere pass through air inlet duct (10), air admission hole (12) is connected with liquid flowing tube, and liquid in pipe can be flowed out under its action of gravity naturally.As seen, as long as pinching advances, vent valve and gas admittance valve rubber sleeve (6) on the discharge opeing control volume (5), with regard to suction, the row of may command to liquid.
The utility model has the advantages that easy and simple to handlely, inhale, discharge opeing accurately, rapidly, it can be applied to the chemical analysis in the fields such as agricultural, medical science, biology, chemical industry, metallurgy, geology.
Claims (2)
1, a kind of suction pipe liquid getting device, by air bag (4), suction, discharge opeing control volume, liquid flowing tube constitute; It is characterized in that being equipped with on the air bag one-way exhaust valve, its air intake opening with advance, discharge opeing control volume one end is connected; The rhabodoid (5) that advance, the discharge opeing control volume is hollow, its epimere and hypomere are established vent valve and gas admittance valve respectively, wherein vent valve is by type of tamper evidence (9), be positioned at the type of tamper evidence both sides and be communicated with the also inlet and outlet hole (8) of corresponding distribution, be enclosed within the resilient sleeve (6) that makes the inlet and outlet hole airtight on the rhabodoid and constitute with the hollow rod shape body; Gas admittance valve is by the type of tamper evidence (11) of hollow, the air admission hole that is communicated with the body of rod (12), the air inlet duct in the shaft-like outside (10), and be enclosed within the airtight resilient sleeve of air admission hole (12) is constituted, another termination hollow rubber plug (7) of the body of rod is connected with liquid flowing tube by it.
