Abstract
The utility model relates to a kind of unidirectional autocontrol valve, comprises valve body, valve gap, valve rod and flap, and described flap is the isosceles trapezoid of standing upside down, and is provided with the isosceles trapezoid valve port coincide with described flap in described valve body; The underpart of described flap is disposed with compressible gasket and seal ring from top to bottom; The top of described flap is provided with diaphragm, and the upper end of described diaphragm is provided with barrier film platen; The liquor inlet of described valve body is provided with the curved channel of first convex recurve, and the liquid outlet of described valve body is provided with first recessed rear convex curved channel; Therefore the utility model makes the opening and closing of valve port can realize gradually opening gradually closing, and reduces the pressure difference opened and closed instantaneously, extends the working life of valve; The curved channel design of liquor inlet and liquid outlet makes the liquor inlet of valve and liquid outlet to keep in liquid, avoids the large pressure difference of opening instantaneously, is more suitable for the control system of ask for something low flow velocity.
Description
Technical field
The utility model belongs to automatic control equipment field, particularly relates to a kind of unidirectional autocontrol valve.
Background technique
One-way control valve mainly plays the effect of a cut-off and conducting to liquid, apply extensive especially in industrial or agricultural and daily life.There is following problem in existing most of one-way control valve, in its valve body valve port cut-off and to open be all moment, cause pressure difference inside and outside valve port very large, to the compressive resistance of valve body itself and anti-impact force requirement higher, valve body is fragile; Time valve port of valve body is closed, liquor inlet has liquid, and liquid outlet is air, and pressure difference is very large, there will be rapid liquid stream when opening instantaneously, when applying in some tank level control systems, and the accuracy of meeting influential system.
Summary of the invention
The technological scheme that the utility model is taked for the technical problem existed in solution known technology is to provide a kind of unidirectional autocontrol valve, comprise valve body, valve gap, valve rod and flap, described flap is the isosceles trapezoid of standing upside down, and is provided with the isosceles trapezoid valve port coincide with described flap in described valve body; The underpart of described flap is disposed with compressible gasket and seal ring from top to bottom; The top of described flap is provided with diaphragm, and the upper end of described diaphragm is provided with barrier film platen; The liquor inlet of described valve body is provided with the curved channel of first convex recurve, and the liquid outlet of described valve body is provided with first recessed rear convex curved channel.
According to a preferred embodiment of the present utility model, the structure of described curved channel is, staggers to be provided with and protrude hemisphere and lower protrusion hemisphere in the upper and lower end face in valve body; The bottom tangent of described upper protrusion hemisphere and lower protrusion hemisphere is in same level, and its centre of sphere spacing is the twice of the width of described valve port.
The utility model can also take following technical measures:
1. in order to strengthen anti-overflow performance and the sealability of whole control valve, be provided with interior ring in described valve gap, this interior ring was around described barrier film platen one week.
2. conveniently control this valve, the top device of described valve gap has control gear.
The advantage that the utility model has and good effect are: because the utility model adopts as above technological scheme, by the isosceles trapezoid that flap design becomes to stand upside down, make the opening and closing of valve port can realize gradually opening gradually closing, reduce the pressure difference opened and closed instantaneously, extend the working life of valve; The curved channel design of liquor inlet and liquid outlet makes the liquor inlet of valve and liquid outlet to keep in liquid, avoids the large pressure difference of opening instantaneously, is more suitable for the control system of ask for something low flow velocity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A sectional view in Fig. 1.
In figure: 10, valve body; 11, liquor inlet; 12, liquid outlet; 13, curved channel; 14, upper protrusion hemisphere; Protrude hemisphere 15 times; 20, valve gap; 21, interior ring; 30, valve rod; 40, flap 50, compressible gasket; 60, seal ring; 70, diaphragm; 80, barrier film platen; 90, control gear.
Embodiment
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 to Fig. 2, the technical solution of the utility model is to provide a kind of unidirectional autocontrol valve, comprise valve body 10, valve gap 20, valve rod 30 and flap 40, described flap 40 is the isosceles trapezoid of standing upside down, and is provided with the isosceles trapezoid valve port coincide with described flap 40 in valve body 10; The underpart of flap 40 is disposed with compressible gasket 50 and seal ring 60 from top to bottom; The top of flap 40 is provided with diaphragm 70, and the upper end of diaphragm 70 is provided with barrier film platen 80; The liquor inlet 11 of described valve body 10 is provided with the curved channel 13 of first convex recurve, and the liquid outlet 12 of valve body 10 is provided with first recessed rear convex curved channel 13.
The structure of curved channel 13 is: stagger to be provided with and protrude hemisphere 14 and lower protrusion hemisphere 15 in the upper and lower end face in valve body 10; The bottom tangent of upper protrusion hemisphere 14 and lower protrusion hemisphere 15 is in same level, and its centre of sphere spacing is the twice of valve port bottom width.
Be provided with interior ring 21 in valve gap 20, this interior ring 21 was around described barrier film platen 80 1 weeks; The top device of valve gap 20 has control gear 90.
Working procedure of the present utility model is:
When Open valve, because flap 40 is the isosceles trapezoid of standing upside down, the unlatching of valve port is made to become large gradually; Curved channel 13 design of liquor inlet 12 and liquid outlet 12 makes the liquor inlet 12 of valve and liquid outlet 12 to keep in liquid, and temporary liquid can first squeeze out by liquid lentamente that flow into from liquor inlet 12, then circulates gradually.
Valve port can be made when throttle down to diminish gradually until close tight.
Above an embodiment of the present utility model has been described in detail, but described content being only preferred embodiment of the present utility model, can not being considered to for limiting practical range of the present utility model.All equalizations done according to the utility model application range change and improve, and still all should belong to patent of the present utility model and contain.
