Description
Technical field
The present invention relates to valve, more particularly to a kind of combined type check-valves.
Background technology
Valve is that one or more opening or passage are blocked come open and close or partly using a movable part, makes liquid
Stream, air stream or other air-flows or a large amount of bulk materials can flow out, block or a kind of adjusted device.Check-valves refers to
Flowed in itself by medium and automatic open and close flap, for preventing the valve of medium refluence.Check-valves belongs to a kind of automatic valve
Door, more installed in pump outlet, its main function is to prevent medium from flowing backwards, prevent pump and drive motor from inverting.Check-valves
Mainly it is made up of valve body, flap, bonnet, valve shaft.At present, the check-valves pattern of in the market is various, but debris is stuck in the medium
When at flap, flap can not normal switching-off, non-return defective valve is required for shutdown to tear maintenance of valve open.
The content of the invention
It is an object of the invention to provide one kind it is simple in construction, cheap, separation of solid and liquid can be realized, band can be realized again
It is pressed in the combined type check-valves that line is removed contamination.
In order to solve the above technical problems, combined type check-valves of the present invention, including threeway main body, set in threeway main body
There is horizontal water inflow pipe, the outlet pipe that tilts upward and blow-off pipe vertically downward；Check valve body is provided with outlet pipe, flap is set
In in check valve body, the water inlet end of flap is through the affixed garbage barrier net of bolt；Arc seal plate is provided with blow-off pipe, sealing is flat
One end of plate is connected with 1# handwheels provided with sealing voussoir, the other end of seal plate；Bottom is domed section of dirty basket positioned at close
Seal on flat board, cut dirty basket bottom and be evenly equipped with several holes；Seal plate be located at lowering or hoisting gear on, lowering or hoisting gear include elevating lever and
It is caught platform, one end of elevating lever and platform of being caught are connected, and the other end and 2# handwheels of elevating lever are affixed, the top for platform of being caught
For arc, elevating lever passes through the bottom of bottom, and bottom is connected with blow-off pipe through U-clamp；Bottom is provided with relief valve.
As a further improvement on the present invention, the angle of water inlet pipe and outlet pipe takes 90 °~150 °.
As a preference of the present invention, the height for cutting dirty basket is more than 2 times of seal plate thickness less than the 4 of seal plate thickness
Times；Cut dirty basket internal diameter C and be more than blow-off pipe import internal diameter A less than blow-off pipe exit inside diameter B.
During normal work, cut dirty basket bottom and fall in seal plate, seal plate is closed.Start water pump, be situated between
Matter flows to the debris in check-valves, medium because of the stop of garbage barrier net from water inlet through garbage barrier net, it is impossible to enter check-valves.Due to going out
Water pipe is tilted upward, media impingement tube wall and garbage barrier net, and flow velocity weakens, and the debris in medium under the low speed, can be all because conducting oneself with dignity
Fall and cutting in dirty basket.When needing to remove contamination, seal plate is opened, dirty basket is cut and falls on lowering or hoisting gear, operate lowering or hoisting gear, will cut
Dirty basket position is dropped to below seal plate, turns off plate seal.Open after the relief valve pressure release on lowering or hoisting gear, no pressure,
Pull down lowering or hoisting gear, the debris that cleaning is cut in dirty basket.After the completion of cleaning work, the clean dirty basket that cuts is placed on lowering or hoisting gear,
By lowering or hoisting gear integral installation on the bottom blow-down pipe of threeway main body, relief valve is closed, seal plate is opened, risen dirty basket is cut
To top, seal plate is closed, the arc surface of flat board end is in contact with cutting dirty basket, and with the closing of seal plate, sealing is flat
Plate, which can push, cuts dirty basket rising, until flat board is completely closed, online completion of removing contamination with pressure.
Beneficial effects of the present invention in summary：The design that outlet pipe is tilted upward, it is possible to decrease flow velocity, falls beneficial to debris
Under, delivery port is provided with the design of garbage barrier net with holes, and debris can be prevented to enter non-return valve insertion；Threeway bottom part body blow-off pipe is cut
Dirty basket, cuts a dirty basket bottom and is evenly equipped with several holes, refuse collecting is conducive to beneficial to separation of solid and liquid, cut dirty basket lower seal flat board and
The design of lowering or hoisting gear, can be achieved line again with pressure and removes contamination；It is spherical, the platform top of being caught on lowering or hoisting gear to cut dirty basket bottom
It is cambered surface with seal plate upper end, when the platform on elevating mechanism rises to certain altitude, closes seal plate, sealing is flat
Plate cambered surface is that spherical crown is in contact with cutting dirty basket bottom, and section dirty basket can be promoted up, meanwhile, 2 times more than seal plate thickness are small
In 4 times of seal plate thickness, dirty basket internal diameter C is cut equal more than the design that blow-off pipe import internal diameter A is less than blow-off pipe exit inside diameter B
Up and down motion to cut dirty basket, which rises, to provide safeguard.It can be seen that the combined type check valve structure of use above-mentioned technical proposal is simple, cost
It is cheap, separation of solid and liquid can be realized, can realize and with pressure remove contamination online again.
