Description
Technical field
The utility model belongs to plumbing valve field, is related to a kind of floating box type flap valve.
Background technology
Flap valve is mounted in a kind of check valve at rivers seashore side or supply and drain water system pipe water outlet, and it is by flap valve
Pressure difference inside and outside lid realizes unlatching and the closure of door-slapping cover, and when tidewater is higher than water level in pipe, flap valve can be automatically switched off, resistance
Exhausted tidewater enters pipeline, prevents sea, river, river from pouring in down a chimney.When tidewater debarks under wind-force effect, water on the bank can pass through flap valve again
Flow into rivers.
Current flap valve construction is made up of door-slapping cover, flap valve seat, is in 3~5 ° of inclination angles in vertical elevation, is beneficial to flap valve and is existed
Tight closing under Action of Gravity Field.Reality when using, when tidewater, unrestrained impulsive force are larger, and shock height be under flap valve along when,
Flap valve can be opened by tidewater, be poured in down a chimney into a part of tidewater.At present, mostly end socket on the market it is ellipse head or dome head,
Profile unsightly and is behaved dumb and not sturdy and durable enough.
Utility model content
Above-mentioned in order to solve the problems, such as, the utility model provides a kind of floating box type flap valve, flap valve simple structure, beautiful outline form
See, the sound construction of door-slapping cover, impact resistance is durable in use, flap valve opens convenient, and sealing is tight.
To achieve the above object, the technical scheme that the utility model is used is as follows：
A kind of floating box type flap valve, including flap valve seat and with flap valve seat by the rotational pin door-slapping cover that is connected of rotation, institute
The bottom border for stating flap valve seat is welded with ring flange, and the delivery port end face circumference inner ring of the flap valve seat is provided with sealing ring, described
The inner surface of door-slapping cover be welded with " ten " font or " well " font reinforcement.
Used as restriction of the present utility model, the door-slapping cover is shaped as arch.
Floating box type flap valve provided by the utility model, simple structure, good appearance, flap valve interior surface is provided with reinforcement
The sound construction of door-slapping cover afterwards, impact resistance is durable in use, and flap valve opens convenient, and sealing is tight.
The utility model is used in installed in the pipe end needed to river sea draining.
Brief description of the drawings
Fig. 1 the utility model embodiment floating box type flap valve along vertical central axis direction sectional side elevation；
Fig. 2 is the inner surface structure schematic diagram of door-slapping cover in Fig. 1；
In figure：1- flap valves seat, 2- door-slapping covers, 3- reinforcements, 4- sealing rings, 5- ring flanges, 6- rotational pins.
Specific embodiment
A kind of floating box type flap valve of embodiment
The present embodiment is a kind of floating box type flap valve, as shown in figure 1, it includes flap valve seat 1 and the flap valve being hinged with flap valve seat 1
Lid 2, i.e.,：Door-slapping cover 2 is rotated by the rotational pin 6 of stainless steel with flap valve seat 1 and is connected（On the basis of the direction shown in Fig. 1,
Rotational pin 6 is rotated upwardly and downwardly, so as to realize the opening of door-slapping cover 2 and close）.In order to be connected with drainage pipeline, the bottom of flap valve seat 1
Border is welded with ring flange 5, by the connection of ring flange 5 and drainage pipeline.
Actual when using, the direction shown in the flap valve with Fig. 1 of the present embodiment is as horizontal plane, flap valve turns clockwise
After 90 °, ring flange 5 is connected with drainage pipeline and can be used.When tidewater, sea beat power are larger, and shock height is in and claps
Under door along when, flap valve can be opened by tidewater, be poured in down a chimney into a part of tidewater, in order to prevent the generation of the phenomenon, the water outlet of flap valve seat 1
Mouth end face circumference inner ring is provided with sealing ring 4, and sealing ring 4 is ethylene propylene diene rubber, and sealing ring 4 can be such that door-slapping cover 2 seals tightly.
In order to strengthen the strength and stability of door-slapping cover 2, door-slapping cover 2 is shaped as arch, the inner surface welding of door-slapping cover 2
There is " ten " font reinforcement 3, " ten " the font reinforcement 3 in the present embodiment is located at the centre of the inner surface of door-slapping cover 2, such as
Shown in Fig. 2, it is of course also possible to change the setting form of reinforcement 3 according to the actual needs, such as reinforcement 3 can be set to " well "
Font.
After installing flap valve, when pipeline has water, due to the percussion of current, the door-slapping cover 2 of flap valve is automatically opened up, by water
Enter river marine, after draining, door-slapping cover 2 is automatically switched off in the presence of deadweight, realize the check of flow passage one-way unlatching and break
The effect of stream.
The structure of the floating box type flap valve not described in the present embodiment uses prior art.
Above-described embodiment, is only preferred embodiment of the present utility model, is not its that made to the utility model
The restriction of its form, any those skilled in the art are changed or are changed possibly also with above-mentioned technology contents as enlightenment
Type is the Equivalent embodiments of equivalent variations.In every case it is the technical spirit without departing from the utility model claim, implements to more than
Simple modification, equivalent variations and remodeling done by example, still fall within the utility model protective scope of the claims.
