Abstract

An anti release jam leakage device mainly comprises a valve body, an anti release jam leakage switch and a buoy. The switch is connected with a lower part edge of the valve body through a gemel and the buoy is hinged with the other end of the switch. The utility model has advantages of simple structure, low manufacturing costs, good sealability, anti aging and corrosion protection.

Description

A kind of anti-leak stopping device of letting out

The utility model relates to a kind of anti-leak stopping device of letting out of appearance foreign matter obstruction of town dweller's common sewer.

At present, employed anti-effect and poor reliability of letting out the device for plugging majority owing to complex structure, sealing difference or use, and fail widely to popularize.

The purpose of this utility model is to provide a kind of use reliable, simple in structure, has good airproof performance, the anti-leak stopping device of letting out of anti-aging, erosion-resisting sewer.

For achieving the above object, the scheme that the utility model adopts is, provide mainly by valve body 1, the counter anti-leak stopping device of letting out of letting out leak stopping switch 6 and buoy 8 compositions, valve body 1 is made up of with inner core 4 outer core 3, roughness according to the sewer inwall adopts anticorrosive, anti-aging, have elastomeric rubber and be made into the counter outer core 3 of letting out leak stopping device valve body 1, and process the protruding circle 2 of a plurality of annulars at its outer wall, to increase the sealing and the rate of tension of itself and sewer, to reach the purpose of anti-back-pressure, the inner core 4 of valve body 1 adopts plastic pipe to make, the lower end of inner core 4 is made into counter and lets out the half round post that leak stopping switch 6 matches, so that normal draining, to have elastomeric outer core 3 at last and be pressed into an integral body formation valve body 1 with inner core 4 sprays, counter let out leak stopping switch 6 be one the band convex edge half round post, and be connected to the lower edge of valve body 1 by hinge, state when it is sagging at ordinary times matches with the shape of sewer tube wall, to reduce taking to the sewer space, be convenient to normal draining, simultaneously also be hinged with a half-cylindrical buoy 8 below the leak stopping switch 6 counter letting out, state when it is sagging at ordinary times also matches with the shape of sewer tube wall, to reduce taking to the sewer space, this come-up when water blockoff is so that close in advance, instead lets out leak stopping switch 6 and buoy 8 all can be around pin joint 5 separately, 7 rotate up and down.

The utlity model has following advantage:

1, simple in structure, cost of manufacture is low;

2, has elastomeric rubber owing to having adopted, so good airproof performance;

3, employed material has advantages such as anti-aging, erosion-resisting function.

Below in conjunction with accompanying drawing the utility model is further described:

During making, roughness at cast iron and plastics sewer inwall is big, friction factor is big, characteristics such as closely connected property difference, adopt anticorrosive, anti-aging, have elastomeric rubber and be made into the counter outer core 3 of letting out leak stopping device valve body 1, and process the protruding circle 2 of a plurality of annulars at its outer wall, preferably make the protruding circle 2 more than 3, to increase the sealing and the rate of tension of itself and sewer, to reach the purpose of anti-back-pressure, the inner core 4 of valve body 1 adopts plastic pipe to make, so that normal draining, the lower end of inner core 4 makes with counter and lets out the shape that leak stopping switch 6 matches, to have elastomeric outer core 3 at last and be pressed into an integral body formation valve body 1 with inner core 4 sprays, instead let out leak stopping switch 6 is connected to valve body 1 by hinge lower edge, can rotate up and down around its pin joint 5, with counter let out leak stopping switch 6 be made into one the band convex edge half round post, state when it is sagging at ordinary times matches with the shape of sewer tube wall, to reduce taking to the sewer space, simultaneously also be hinged with a half-cylindrical buoy 8 below the leak stopping switch 6 counter letting out, this buoy 8 can rotate up and down around itself and the counter pin joint 7 of letting out leak stopping switch 6, state when it is sagging at ordinary times also matches with the shape of sewer tube wall, to reduce taking to the sewer space, these buoy 8 come-ups close it with the anti-leak stopping switch 6 of letting out of jack-up in advance when water blockoff, instead when using at ordinary times let out leak stopping switch 6 and buoy 8 all keeps hang, and paste mutually with the sewer tube wall, be convenient to normal draining.

During use, owing to instead when using at ordinary times let out leak stopping switch 6 and buoy 8 all keeps hang, and paste mutually with the sewer tube wall, simultaneously because anti-shape of letting out leak stopping switch 6 and buoy 8 hangs matches with the sewer tube wall, subsides mutually, so it is very little to take the space of sewer, can not adhere to foreign matter, can not influence normal draining, when the beginning water blockoff, water rises buoy 8, let out leak stopping switch 6 so that it is closed in advance thereby jack-up is counter, to reach anti-purpose of letting out leak stopping.To scurry on the sewer stink in order preventing simultaneously, can also to place an independent ball on valve body of the present utility model 1 top, be used, effect is better.

Claims

1, a kind of anti-leak stopping device of letting out, mainly by valve body, instead let out the leak stopping switch and buoy is formed, instead let out the leak stopping switch is connected to valve body by hinge lower edge; buoy is articulated in the counter other end of letting out the leak stopping switch; it is characterized in that: valve body is made up of outer core and the inner core of pressing or pouring into an integral body by spray, and the outer wall of outer core has been made into a plurality of annular bead, and inner core employing plastic pipe makes; so that normally draining, the lower end of inner core is made into counter and lets out the half round post that the leak stopping switch matches;

2, the anti-leak stopping device of letting out as claimed in claim 1 is characterized in that: the described anti-half round post that the leak stopping switch is a band convex edge of letting out, and the state when it is sagging at ordinary times matches with the shape of sewer tube wall, to reduce taking the sewer space;

3, the anti-leak stopping device of letting out as claimed in claim 1 or 2, it is characterized in that: buoy be one half-cylindrical and be hinged be connected to counter let out the leak stopping switch other end below, this buoy can rotate around itself and the counter pin joint of letting out the leak stopping switch, state when it is sagging at ordinary times also matches with the shape of sewer tube wall, reducing to the taking of sewer space, this buoy come-up when water blockoff so that the anti-leak stopping switch of letting out close in advance.
