Abstract

The invention discloses a valve structure with a self-adaption function. The valve structure comprises a part provided with a curved surface and a part provided with a smooth surface interface; the part provided with the curved surface is smooth in surface and jointed with a smooth surface of the other part; under certain pressure, the two parts are in close contact, and fluid can be prevented from flowing through the contact surfaces of the two parts. By the valve structure, the problem of poor sealability between the two parts due to the fact that the two parts possibly produce pollution in use is solved.

Description

A kind of valve mechanism with adaptation function

Technical field

The present invention relates to a kind of valve mechanism, relate generally to a kind of valve mechanism with the fluid of adaptive ability .

Background technology

Valve in fluid is common parts in a daily life, for example, in the water tank of flush toilet, just need the valve of a draining, when toilet need to be washed by water, valve open, water in water tank flows out and rinses bedpan, has rinsed late gate and has closed, and water is entered by water intaking valve until the water in water tank reaches certain water level:

In use, because always have some impurity in water, through the longer time, the surface of water discharging valve can be accumulated some dirts, thereby affects the normal use of valve, thereby cause valve to leak, affects the normal use of flush toilet.

Summary of the invention

the present inventionsolve technical problem be to providethe structure of a valve , canin use reduce the generation of dirt, and the seal of the raising valve when having dirt, seepy question solved .

the invention discloses and there is adaptive abilityvalve structure, comprising: one hascurved surface 's, smooth surface, there is certain elasticity parts, one has smooth surface interfaceparts ; Shouldthere is curved surface parts withhave smooth surfaceinterface 'sparts engage, under certain pressure, these parts can be with smooth interface close contact also can prevent the fluid interface of flowing through.

The present invention has the certain flexible parts of having of curved surface by employing, the dirt at energy docking port unit interface place plays certain self-cleaning effect, the dirt of contact position that also can be when contacting with interface unit on curved surface has certain self-cleaning effect, and in the situation that having certain dirt, utilize its elasticity guarantee under certain pressure can with interface unit close proximity, solve parts in use may producethereby dirt cause the problem of poor sealing between the two.

The specific embodiment

The water discharging valve of flush toilet of take is example, when toilet need to be washed by water, valve open, the water in water tank flows out and rinses bedpan, rinsed late gate and closed, water is entered by water intaking valve until the water in water tank reaches certain water level: it is to guarantee not having water to spill from valve that valve closes.

In existing valve mechanism, the contact surface of the upper member of the valve being in contact with one another is plane, while having dirt on the surface of water discharging valve, can not form close contact with the surface of lower member, thereby cause valve to leak, affects the normal use of flush toilet.The present invention, by adopting new valve mechanism, can play certain self-cleaning effect to dirt, and in the situation that having certain dirt, upper member can with lower member close proximity, solve parts in use may producethereby dirt cause between the two the problem of poor sealing.

Fig. 1 is the partial cross section schematic diagram of first valve using now, and wherein lower member 1 and upper member 2 form valve, and pull-up upper member 2 during valve open, puts down upper member 2 during valve closing, make upper member 2 and lower member 1 close contact.Wherein upper member 2 can have at least a square part to be positioned at bottom, and the part of the parts 2 that parts 1 and parts 2 directly contact is planes.

Fig. 2 is the partial cross section schematic diagram of second valve using now, and wherein lower member 1 and upper member 2 form valve, and pull-up upper member 2 during valve open, puts down upper member 2 during valve closing, make upper member 2 and lower member 1 close contact.Wherein upper member 2 can have at least the part of an arc to be positioned at bottom, and the part of the parts 2 that parts 1 and parts 2 directly contact is planes.

Fig. 3 is the schematic diagram that dirt produces, and wherein lower member 1 and upper member 2 form valve, and when valve open, owing to there being certain impurity in water, long-time use can form one deck dirt 3 on the surface of lower member 1 and upper member 2.

Fig. 4 is the schematic diagram that dirt leaks while existing, and wherein lower member 1 and upper member 2 form valves, and when valve closing, due to the existence of dirt 3, lower member 1 and upper member 2 be close contact comprehensively, thereby causes valve to leak.

Fig. 5 is an a kind of pictorial diagram of drainage valve of flush toilet, when the surface that upper-part contacts with lower member exists dirt, will cause valve to leak.

Fig. 6 is the schematic cross-section of the first scheme of the present invention, lower member 1 and upper member 4 form valve, upper member 4 is spheres, the part that during valve closing, upper member 4 contacts with lower member is a curved surface, this spheroid rigidity can not be too high, the modulus of elasticity of its use material will be lower than 20Mpa, and material can be rubber; Parts 1 can be lower member as shown in Figure 5.

Further scheme upper member 4 can be a part of spheroid, as 1/2 ball, or 1/3 ball (not shown).

Further scheme is the surface (not shown) that there is a wedge shape parts 1 inner side, and the roughness of wedge-shaped surface is less than 0.2 millimeter, so further makes upper member 4 and lower member 1 can be easier to close contact.

Fig. 7 be in the first scheme afternoon a parts top view of 1, lower member 1 can be the parts of a circular ring type.

Fig. 8 is the first scheme the close situation of dirt under existing, and because the contact surface of upper member is a sphere, and has certain elasticity, and upper member, under the effect of the pressure of water, can be cleaned the dirt of contact surface, and removes.In the situation that having certain dirt, upper member and lower member energy close contact, prevent that drainage from occurring.

Fig. 9 is the schematic cross-section of first scheme of the present invention, lower member 1 and upper member 5 form valve, upper member 5 is ellipse spheres, the part that during valve closing, upper member 1 contacts with lower member 1 is a curved surface, this spheroid rigidity can not be too high, it uses the modulus of elasticity of material will be lower than 20Mpa, can material rubber material.

Further scheme upper member 5 can be a part of spheroid, as 1/2 ellipsoid, or 1/3 ellipsoid (not shown).

Further scheme is the surface (not shown) that there is a wedge shape parts 1 inner side, and the roughness of wedge-shaped surface is less than 0.2 millimeter, so further makes upper member 5 and lower member 1 can be easier to close contact.

Figure 10 is the schematic cross-section of the third scheme of the present invention, lower member 1 and upper member 6 form valve, upper member 6 is parts with curved surface at least partly, the part that during valve closing, upper member 6 contacts with lower member 1 is a curved surface, these upper member 6 rigidity can not be too high, it uses the modulus of elasticity of material lower than 20Mpa, can adopt elastomeric material.

Further scheme is the surface (not shown) that there is a wedge shape parts 1 inner side, and the roughness of wedge-shaped surface is less than 0.2 millimeter, so further makes upper member 6 and lower member 1 can be easier to close contact.

The valve of above-mentioned three kinds of schemes, at the pressure of liquid during higher than 0.1cm water column,top partswith lower member can close contact also can prevent the fluid interface of flowing through.

by specific embodiment, the present invention is had been described in detail above, but that these not form is right restriction of the present invention.Without departing from the principles of the present invention, those skilled in the art also can do go out many distortion and improvement, these also should be considered as protection scope of the present invention.
