Abstract
The utility model relates to a double clack valve which comprises a valve body and a flap, wherein the flap is connected with a bar of the valve body by a pin bearing, a hole is equipped on the flap, a small flap is covered on the hole, and the small flap is connected with the flap by the pin bearing, with the advantages of auto adjusting saving flow, on the one hand, force of impact on the valve body is small and the using life is long, on the other hand, the fluid receives little resistance, can let fluid of little flow pass by, and can be opened freely without noise and a environment polluting effect.
Description
Technical field
The utility model relates to a kind of dual flap valve.
Background technique
Traditional safety check all is to open valve by the fluid strong wallop, and there is following defective in this principle: 1, the suffered resistance of fluid is very big, if the impact force of fluid is big inadequately, then can't open valve; 2, fluid also produces great impact force to valve body, and attrition is big, and valve body is impaired easily, and working life is shorter; 3, strong wallop is easy to generate noise, befouling environment.
Summary of the invention
The purpose of this utility model is to provide a kind of keying dual flap valve freely.
The utility model is implemented by the following technical programs: this 1 inner chamber of valve is provided with a flap 2, and flap 2 is connected with bearing pin 4 with the internal chamber wall of valve body 1, establishes a little flap 3 on the flap 2 in addition, and little flap 3 is connected with bearing pin 5 with flap.
Compare with conventional check valves, the utlity model has following advantage: 1, dual flap valve is provided with two flaps that vary in size, and can regulate the size of flow automatically; 2, fluid is little to the impact force of valve body, can improve the working life of dual flap valve greatly; 3, the resistance that is subjected to of fluid is little, and the fluid of small flow still can be opened flap automatically; 4, do not have noise, have environment protection effect.
Description of drawings
Accompanying drawing 1 cuts the planing surface structural representation of safety check for a kind of dual lobe formula.
Accompanying drawing 2 cuts the little flap schematic representation of safety check for a kind of dual lobe formula.
Embodiment
Cut shown in the planing surface structural representation of safety check and the little flap schematic representation that 2 one kinds of dual lobe formulas of accompanying drawing are cut safety check as a kind of dual lobe formula of Fig. 1.
A kind of dual flap valve comprises valve body 1, flap 2, wherein, establishes a little flap 3 in addition on flap 2, and little flap 2 is connected with flap 2 bearing pins 3.
A kind of dual flap valve, described little flap can be the round valve sheet, also can be the polygonal valve block, as six rhombuses, rectangle etc.
Claims (2)
1, a kind of dual flap valve comprises valve body, flap, it is characterized in that: offer a through hole on flap, little flap covers in the through hole.
2, a kind of dual flap valve according to claim 1, it is characterized in that: described little flap connects flap with bearing pin.
