Abstract
The utility model provides a check valve with an elastic convex plug, which is characterized in that an elastic valve clack formed by one-time compression moulding is arranged on an elastic plane, and the elastic valve clack can be opened and is provided with narrow slit in the middle; When liquid flows from a positive direction, the narrow slit on the valve clack is opened; when the liquid flows in an opposite direction, the valve clack is closed due to the pressure of the liquid, making the liquid only flow in single direction. The utility model can be widely used in equipment with corrosive liquid.
Description
The utility model belongs to the improvement to one-way cock in the liquid capacity-changing mechanical.
In the process that transports liquid, gas, be unable to do without various types of valves and various pump, wherein the using scope of one-way valve is also very extensive.General one-way valve all adopts the mechanical type one-way valve, because the mechanical type one-way valve will have spring to oppress pellet shot from a slingshot or thimble constitutes one-way valve, so when conveying was corrosive liquid, the spring of one-way valve and pellet shot from a slingshot can very fast corrosion, cause the valve subscription rate.And required precision height during the manufacturing of mechanical type one-way valve, during work because the impact noise of pellet shot from a slingshot is also bigger.
The purpose of this utility model is at above deficiency, provides a kind of simple in structure, and valve opening and closing speed is fast, low noise and corrosion resistant one-way valve.
Technological points of the present utility model is, is shaped on the elasticity convex flap that has narrow slit in the middle of on an elastic plate.Two lobes of elasticity convex flap can be opened closed.In order to increase elasticity, the behind of elasticity convex flap is a groove.
Fig. 1 is the schematic representation of elasticity convex plug one-way valve under closed state
Fig. 2 is the schematic representation of elasticity convex plug one-way valve under opening state
Fig. 3 is that elasticity convex plug one-way valve A-A is to sectional view
As an embodiment of the present utility model as shown in the figure; Wherein (1) is elastic plate, and (2) are the middle elasticity convex flaps that has narrow slit (3) on the elastic plate, and (4) are elasticity convex flap grooves behind, and (5) are supports.When liquid when behind groove flows through flap from elasticity convex flap, the flowing pressure of liquid is washed elasticity convex flap open, and liquid passes through.If when groove direction flowed, because the pressure of liquid is the flap closure, along with the increase of pressure, flap was closed tighter, and liquid can not be flow through from elasticity convex flap for liquid.In order to increase the intensity of flap, in elasticity convex flap groove behind, a support with holes that matches with the groove body is housed.Support can be by the strong nylon formula engineering plastics die forming of corrosion resistance.Elasticity convex flap can be two halves, also can be multi-petal shape.
The utility model is simple in structure, when being used for corrosive liquids of different nature, can select other elastomeric material once die stamping forming of rubber type of different materials.
