Abstract
The utility model relates to a kind of energy-saving side-turning type flap valve multiple field sealing devices, including buffer unit ontology and fixing screws, left silencing cavity is set on the left of buffer unit ontology, right silencing cavity is set on the right side of buffer unit ontology, elastic sealing strip is arranged in the right silencing cavity upper right corner, it is intermediate silencing cavity among buffer unit ontology, mounting hole is set below intermediate silencing cavity, fixing screws pass through mounting hole and connect buffer unit ontology with flap valve seat front end flange, and buffer unit body upper surface is arc contact surface.When the utility model is installed on flap valve seat forward flange, when door-slapping cover is fallen after rise when water pump is shut down, it is in soft landing shape, buffer function can be effectively acted as, reduce impact force when door-slapping cover is fallen after rise；When flap valve is closed, the through-hole and upper right corner elastic sealing strip of two sides of left and right are set, under the action of flap valve self weight and static pressure, complementary shape is sealed, and sealing effect is good.
Description
Technical field
The flap valve used the utility model relates to irrigate drainage pumping stations water outlet end, specifically one kind are installed on section
Sealing device on energy type side-turning type flap valve seat.
Background technique
In recent years, cutout (sealing) device of the domestic row of filling gargoyle of pumping station end, has greatly design, installation to make
With energy-saving side-turning type flap valve, and its bore increasingly becomes big；The impact force problem that water pump shuts down when flap valve is fallen after rise causes use
Family and insider (R&D institution, flap valve manufacturer etc.) extensive concern.In recent years, larger caliber flap valve impact force problem is coped with
Measure: the overwhelming majority use hydraulic slow closing device.But technique is applied for many years, and there are the following problems:
1. Leakage: above-mentioned flap valve is mostly that submerged goes out to flow, and hydraulic damping device is run under water throughout the year, and to be answered
To various medium waters (silt water, sewage), oil leak not can avoid.
2. card resistance problem: since flap valve is run under water for a long time, ring wear water inlet is can hardly be avoided into foreign matter.It is equipped with
The generally existing card resistance problem of the flap valve of hydraulic slow closing device, is particularly acute within the border in Yellow River basin.Some users simply remove this
Slow closing device not only causes the waste of resource.And affect the normal use of flap valve.
Summary of the invention
The utility model is in view of the above-mentioned problems, a kind of energy-saving side-turning type flap valve multiple field sealing device, including buffering fill
Ontology and fixing screws are set, left silencing cavity is set on the left of the buffer unit ontology, setting is right on the right side of the buffer unit ontology
Elastic sealing strip is arranged in silencing cavity, the right silencing cavity upper right corner, is intermediate silencing cavity among the buffer unit ontology, described
Mounting hole is set below intermediate silencing cavity, and the fixing screws pass through the mounting hole for the buffer unit ontology and flap valve seat
Front end flange connection, the buffer unit body upper surface are arc contact surface.
It is further improved as the utility model, the buffer unit ontology is made of nitrile rubber.
It is further improved as the utility model, pressing plate is set between the fixing screws and the buffer unit ontology.
It is further improved as the utility model, the pressing plate and the fixing screws are made of stainless steel material.
It is further improved as the utility model, buffer unit ontology bottom surface is circular arc concave surface, with the flap valve seat
Forward flange surface forms damping chamber.
The utility model compared with prior art, has the advantages that
1, the utility model is simple and reasonable, safe and reliable, occupies little space.
It 2, is in soft landing shape when water pump is shut down, door-slapping cover is fallen after rise when the utility model is installed on flap valve seat forward flange,
Buffer function can be effectively acted as, impact force when door-slapping cover is fallen after rise is reduced；When flap valve is closed, the logical of two sides of left and right is set
The mobilizable sealing strip in hole and the upper right corner, under the action of flap valve self weight and static pressure, complementary shape is sealed, and sealing effect is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing:
It include: buffer unit ontology 1 in Fig. 1, right silencing cavity 2, left silencing cavity 3, pressing plate 4, fixing screws 5, before flap valve seat
End flanges 6, elastic sealing strip 7, damping chamber 8, left arc contact surface 11, right arc contact surface 12, intermediate silencing cavity 9, mounting hole
10 etc..
The utility model as shown in Figure 1 is a kind of energy-saving side-turning type flap valve multiple field sealing device, including by butyronitrile rubber
Buffer unit ontology 1 made of glue, left silencing cavity 3 is arranged on the left of buffer unit ontology 1, and right silencing cavity 2, right noise reduction is arranged in right side
Elastic sealing strip 7 is arranged in 2 upper right corner of chamber, is intermediate silencing cavity 9 among buffer unit ontology 1, peace is arranged below intermediate silencing cavity 9
Fill hole 10, fixing screws 5 pass through mounting hole 10 buffer unit ontology 1 is connect with flap valve seat front end flange 6, fixing screws 5 and
Pressing plate 4 is set between buffer unit ontology 1, and pressing plate 4 and fixing screws 5 are made of stainless steel material.1 bottom surface of buffer unit ontology
For circular arc concave surface, damping chamber 8 is formed with 6 surface of flap valve seat front end flange.1 upper left surface of buffer unit ontology is the contact of left arc
Face 11,1 right upper of buffer unit ontology are right arc contact surface 12.
The course of work of the utility model is as follows: flap valve right silencing cavity 2 when being closed, and left silencing cavity 3, subtracts intermediate silencing cavity 9
Shake chamber 8 can play buffering, sound deadening, and left arc contact surface 11, right arc contact surface 12 can increase contact when flap valve closure
Area can significantly reduce impact force when flap valve is fallen after rise, extend the service life of flap valve, and after flap valve is closed, elasticity is close
Flexible deformation under the action of static pressure of strip of paper used for sealing 7 is tilted to the left and can inhale the leakproofness for being attached to increase flap valve in door-slapping cover side.
