Abstract
The utility model discloses a cylindrical right-side opening self-closing slap door valve; a valve body is arranged in front of a rear flange; a front flange is arranged in front of the valve body; a water seal is arranged in front of the front flange; a slap door is arranged in front of the water seal; a hinge chain is arranged on the right side of the front surface of the front flange; the slap door is mounted on the hinge chain; 12 screw bolt holes with equal distances are arranged on the rear flange; the technical keys of the utility model include that the slap door is designed to be a floating box; the hinge chain on the right side of the front flange of the valve body is arranged uprightly; the screw bolt holes 7 on the rear flange are moved to the right in 5 degrees, making the central line as the reference; thereby, after the cylindrical right-side opening self-closing slap door valve is opened, the horizontal component force of the self-weight of the slap door is used as the power to realize the purpose of reducing the opening resistance of the slap door and automatic closing.
Description
Technical field
The utility model discloses the self-closing flap valve valve of a kind of cylinder type right side open type.
Background technique
At present, what the cutout facility of home and abroad irrigation and drainage pumping station generally used is suspension type flap valve valve, and this flap valve valve exists opening angle little, and resistance to water-flow is big, the many and only cutout of energy loss, defective such as do not control flood.Up to the present, on market, also do not see the self-closing flap valve valve of a kind of cylinder type right side open type as yet.
Summary of the invention
The purpose of this utility model provides that a kind of opening angle is big, and resistance to water-flow is little, not only stops but also control flood, and can save the self-closing flap valve valve of cylinder type right side open type of a large amount of energy and manpower and materials.
The technical solution of the utility model is as follows: open type self-closing flap valve valve in a kind of cylinder type right side comprises rear flange, valve body, forward flange, water seal, flap valve, hinge and 12 equidistant bolts hole etc.Wherein, be provided with valve body, be provided with forward flange in the valve body front in the rear flange front, be provided with water seal in the forward flange front, be provided with flap valve, be provided with hinge on the right, forward flange front in the water seal front, flap valve is installed on the hinge, is provided with 12 equidistant bolts hole on rear flange.
Key technology of the present utility model is that flap valve is made floating box type, the hinge on the right, forward flange front is vertically arranged, bolt hole 7 on the rear flange is a benchmark with the center line, all displacement to the right is 5 °, like this, the utility model can utilize the deadweight horizontal component of flap valve to be used as power after installing, the purpose that reaches the opening resistance that reduces flap valve and close door automatically.
