Abstract
The utility model relates to a liquid pressure suction device. The device consists of a piston, a mounting seat, a valve body, a spring, an upper check valve and a lower check valve, wherein the piston is sleeved in a piston cavity formed by the close fit of the mounting seat and the valve body, the upper check valve is positioned at a piston passage port, the lower check valve is positioned at a valve body passage port, the spring is positioned between the upper check valve and the lower check valve, and the upper check valve and the lower check valve are in duckbill shapes with openings. Therefore, the liquid suction and pressure device can normally suck pressure and constantly press liquid no matter in any direction, and avoids dripping and leaking in a natural state, so that the working conditions of the liquid suction and pressure device are diversified.
Description
The utility model relates to one liquid and inhales pressure device.
In daily life, the suction pressure device of liquid adopts structure as shown in Figure 1 usually such as giving the soap valve, by piston 1, mount pad 2, valve body 3, spring 4, go up check (non-return) valve 5, ball check (non-return) valve 6 is formed down.Piston 1 is set in mount pad 2 and valve body 3 and closely cooperates in the plunger shaft that constitutes, and spring is loaded between piston 1 and the valve channel mouth 8, and following ball check (non-return) valve 6 is between valve channel mouth 8 and spring 4.Its principle of work is as follows: when pushing piston, piston moves downward, and the plunger shaft inner volume is dwindled, and pressure increases, and intracavity liquid extrudes by piston channel mouth 7, and ball check (non-return) valve 6 stops up valve channel mouth 8 under gravity and pressure effect down.When piston 1 is replied under the effect of spring restoring force, piston channel mouth 7 is stopped up by last check (non-return) valve 7, and the chamber inner volume increases, pressure diminishes, and following ball check (non-return) valve 6 overcomes the gravity upward movement under pressure, and liquid replenishes in the cavity from valve channel mouth 8.Equilibrium of pressure when spring is replied fully, following ball check (non-return) valve 6 by gravitys are close to valve channel mouth 8, and liquid does not produce mobile.But, inhale pressure device in level or following time of state of certain angle is arranged when liquid, following ball check (non-return) valve 6 just can't come closed valve body porthole 8 according to gravity, just can't guarantee the normal suction pressure of liquid.Still there are some liquid to inhale pressure device, check (non-return) valve all adopts the ball check (non-return) valve about it, these suction pressure devices must could be realized normally pushing under plumbness equally, and have phenomenons such as giving liquid measure instability, easy to leak, bring inconvenience to daily life like this.
At above defective, the purpose of this utility model is to provide a kind of liquid to inhale pressure device, when making it be on any direction, all can realize the normal pressure of inhaling, and constant extrudes liquid, stops water clock under the state of nature.
Liquid of the present utility model is inhaled pressure device, form by piston, valve body, mount pad, spring, last check (non-return) valve, following check (non-return) valve, piston bush is loaded on mount pad and valve body and closely cooperates in the plunger shaft that constitutes, last check (non-return) valve is positioned at the piston channel mouth, following check (non-return) valve is positioned at the valve channel mouth, and spring is between upper and lower check (non-return) valve.Upper and lower check (non-return) valve is the duckbill shape of band opening.
Adopt after the duckbilled check (non-return) valve, liquid non-return just need not device and is in plumbness and relies on gravity to come the closed liquid passage, but changes the unlatching that realizes check (non-return) valve according to the pressure in the plunger shaft, is closure under its state of nature.For this reason, no matter when the suction pressure device of liquid is in any direction, all can normally inhale pressure, give amount constant, water clock not, this just makes its service conditions variation.
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is that existing liquid is inhaled pressure device;
Fig. 2 is an embodiment one of the present utility model;
Fig. 3 is an embodiment two of the present utility model;
Fig. 4 is the duckbilled check (non-return) valve.
As shown in Figure 2, the valve body 2 that the both sides, top respectively have an aperture closely cooperates with mount pad 3, constitute plunger shaft, piston 1 is set in the plunger shaft, piston 1 hollow is fluid passage, and last duckbilled check (non-return) valve 5 is positioned at piston channel mouth 7, and following duckbilled check (non-return) valve 6 is positioned at valve channel mouth 8, spring 4 is between last duckbilled check (non-return) valve 5 and following duckbilled check (non-return) valve 6, and the elastic force of spring 4 is positioned piston channel mouth 7 and valve channel mouth 8 so that go up duckbilled check (non-return) valve 5 respectively with following duckbilled check (non-return) valve 6.Last duckbilled check (non-return) valve 5 and the duckbill shape that following duckbilled check (non-return) valve 6 is a band opening as shown in Figure 4 are closed under the state of nature.Its principle of work is as follows:
1, when pushing piston 1, spring 4 compressions, piston 1 diminishes with the chamber inner volume that valve body 3 forms, and pressure increases, and last duckbilled check (non-return) valve 5 its opening under the big situation of base pressure opens, and liquid flows out by last duckbilled check (non-return) valve 7.And this at present duckbilled check (non-return) valve 6 be that top pressure is big, still remain closed.
When 2, stopping to push piston 1, spring 4 is replied, piston 1 increases with the chamber inner volume that valve body 2 forms, pressure reduces, last duckbilled check (non-return) valve 5 is closed under the big situation in top, prevent liquid return, following duckbilled check (non-return) valve 6 opens at the big situation under shed of base pressure, and liquid is gone in the plunger shaft by following duckbilled check (non-return) valve 6 liquid make-up.
3, when spring 4 returns back to state of nature, equilibrium of pressure, and this moment, upper and lower duckbilled check (non-return) valve all was in closure state, liquid that can not can not reflux by valve channel by the outside trickle of piston channel yet.
As shown in Figure 3, be equipped with guard ring 10, following guard ring 11 on the basis of embodiment one, last guard ring 10 and following guard ring 11 are respectively applied for the location of duckbilled check (non-return) valve 5 and following duckbilled check (non-return) valve 6, spring 4 so more helps duckbilled check (non-return) valve 5 and closely cooperates with valve channel mouth 8 with piston channel mouth 7, following duckbilled check (non-return) valve 6 between last guard ring 10 and following guard ring 11.And piston 1 changes the piston that has seal ring 9 into, makes piston 1 sealing effectiveness in motion process reliable, and it is not misplaced, and is indeformable, air tight, guarantees that liquid quantitative extrudes.The duckbilled check (non-return) valve adopts elastomeric material (as silica gel), because of rubber is light material, can guarantee the duckbilled check (non-return) valve under the big pressure effect in bottom unlatching and the closure under the state of nature.
