Description

Liquid valve

Technical field

The utility model relates to a kind of valving, specifically is Liquid valve.

Background technique

The valve of present widely used controlling liquid flow roughly divides spiral valve and ball type valve door, and there is length switching time in spiral valve, close defective is not closed completely; Though the more spiral valve of ball type valve door has weak point switching time, closes tight characteristics, its structure is complicated, and manufacture cost is high.

The model utility content

The utility model technical problem to be solved is, provide a kind of can snap switch, the Liquid valve of simple in structure, easy to operate, low cost of manufacture.

For solving the problems of the technologies described above, the Liquid valve that the utility model provides comprises the connecting cover that is connected with volumes; The valve body that is fixedly connected with connecting cover is located at the liquid entering hole of connecting cover and valve body joint, is located at the liquid outlet on the valve body; The passage that is communicated with liquid entering hole and liquid outlet; The sealing valve block that matches with liquid outlet with the valve body axial limiting and seal and be located at away from the elasticity gland on the other end valve body of liquid outlet, connects the connecting rod of sealing valve block and elasticity gland.

After adopting above structure, the utility model compared with prior art has following advantage:

1) the sealing valve block is connected through connecting rod with the elasticity gland, because the elasticity gland is by axial limiting, when the elasticity gland receives an axial active force; The distortion of elasticity gland; Through the effect of connecting rod, sealing valve block, connecting rod, elasticity gland form whole interlock, make the sealing valve block form axial motion; Make the sealing valve block detach the liquid mouth, open liquid outlet rapidly; After losing this external force, the elasticity gland links owing to whole because elastic reaction restores; The sealing valve block back axially moves, and sealing valve block and liquid outlet are fitted, and close liquid outlet rapidly; Switch is rapid, makes it the better controlled flow, avoids multithread to go out liquid and makes it waste;

When 2) the control liquid outlet is opened, only need press the elasticity gland; When the control liquid outlet is closed, only need unclamp the elasticity gland, easy and simple to handle;

3) parts are few, and are simple in structure, and cost is low.

As improvement; Described axial limiting and sealing are meant that valve body is provided with seal groove, and seal groove is axial annular groove, and the width between annular groove two walls is slightly less than the thickness of elasticity gland open-mouth end; Firmly make elasticity gland open-mouth end embed annular groove; Elasticity gland open-mouth end receives the extruding of annular groove two walls, and the elasticity gland is fixed, and reaches the effect of axial limiting and sealing.

As further improvement; Circular arc is provided with axial raised setting sleeve in the described elasticity gland, and setting sleeve is an elastic material, and the setting sleeve inwall is provided with radial protrusion; Connecting rod is provided with radial groove; When connecting rod inserted setting sleeve, the radial protrusion of setting sleeve inwall and the radial groove interlock on the connecting rod made the elasticity gland closely be connected with connecting rod.

As further improving, described valve body is provided with guide holder, and the center hole of guide holder cooperates with connecting rod, and the restriction connecting rod produces radial deflection, guarantees that connecting rod axially moves.

As further improving, described elasticity gland is that rubber material is processed again, its original shape of answer and size that can be rapid and strong after receiving external force deformation to withdraw from external force again.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done explanation in further detail.

Structural representation by Fig. 1, the utility model Liquid valve shown in Figure 3 can be known; It comprises the connecting cover 1 that is threaded with volumes; The valve body 8 that is fixedly connected with connecting cover 1, valve body 8 inside are cavity 9, connecting cover 1 is communicated with through liquid entering hole 2 with valve body 8; Also comprise the liquid outlet 3 that is located on the valve body 8; The bowl type that matches with liquid outlet 3 sealing valve block 4 with the valve body axial limiting and seal and be located at away from the elasticity gland 5 on the other end valve body 8 of liquid outlet 3, connects the connecting rod 6 of sealing valve block 4 and elasticity gland 5.

The other end valve body 8 away from liquid outlet is provided with seal groove; Elasticity gland 5 is connected with valve body 8 through seal groove, and seal groove is axial annular groove, and the width between annular groove two walls is slightly less than the thickness of elasticity gland 5 open-mouth ends; Firmly make elasticity gland 5 open-mouth ends embed annular groove; Elasticity gland 5 open-mouth ends receive the extruding of annular groove two walls, make elasticity gland 5 fixing, reach the effect of axial limiting and sealing.

Elasticity gland 5 is provided with axial raised setting sleeve 51; Setting sleeve 51 is a rubber material; Setting sleeve 51 inwalls are provided with radial protrusion, and connecting rod 6 is provided with radial groove, when connecting rod 6 inserts setting sleeve 51; The radial protrusion of setting sleeve 51 inwalls be connected 6 bars on the radial groove interlock, elasticity gland 5 is connected with connecting rod 6.

Can know by Fig. 1, the utility model Liquid valve structural representation shown in Figure 4; Be provided with guide holder 7 in the cavity 9 in the valve body 8, guide holder 7 is a circle structure, is connected valve body 8 inwalls through fixing rod; Connecting rod 6 passes from guide holder 7 circle ring center holes; The internal diameter of annulus is slightly larger than the diameter of connecting rod 6, and restriction connecting rod 6 produces radial deflection, guarantees that connecting rod 6 axially moves

Elasticity gland 5 is a rubber material, is shaped as the U type, elasticity gland 5 by axial limiting on seal groove, when elasticity gland 5 tail ends are applied an axial force, the recessed embedding distortion of elasticity gland 5 tail ends, after removing this active force, elasticity gland 5 tail ends restore.

Can know by structural representation shown in Figure 2, when elasticity gland 5 receives an axial force, the 5 recessed embeddings distortion of elasticity gland; Elasticity gland 5 connects connecting rod 6 through setting sleeve 51; Through the effect of connecting rod 6, valve block 4, connecting rod 6, elasticity gland 5 form whole interlock, make sealing valve block 4 form axial motion; Sealing valve block 4 annulus mouths break away from the annulus mouth of liquid outlet 3, open liquid outlet 3 rapidly.

Can know that by sectional view shown in Figure 1 after losing this external force, elasticity gland 5 is because the elastic reaction recovery; Because whole interlock, sealing valve block 4 back axially moves, and makes tight-lipped closely connected the closing of annulus of sealing valve block 4 annulus mouths and liquid outlet 3; Reach sealing effect, liquid outlet 3 is closed rapidly.

Certainly, the utility model is not limited to the above structure, and wherein guide holder 7 also can be cancelled; Elasticity gland 5 can not be a rubber material, as long as it is an elastomer, after receiving external force deformation to withdraw from external force again, can reply its original shape and size rapidly; Setting sleeve 51 can not be an elastic material, also can be plastic or other material, and connecting rod and setting sleeve can not pass through radial groove and radial protrusion interlock, also can for for be spirally connected, snapping etc.

More than these variations all fall within the protection domain of the utility model.
