Description
Technical field
The invention belongs to water-saving irrigation hydraulic engineering field, be specifically related to a kind of platform float type bottom valve device.
Background technology
Centrifugal pump is the fluid delivery device that water-saving irrigation project is most commonly used, its start work time, pump housing inner chamber with enter
Water must be filled in waterpipe, impeller just can be made to produce enough centrifugal force, water is exported.If pump housing inner chamber and inlet channel
Having air, the gas in inlet channel mixes with water, and the impeller surface at high-speed cruising produces cavitation, causes water pump to damage.Institute
With, centrifugal pump is before activation, it should be ensured that must fill water in pump housing inner chamber and inlet channel and restart.For avoiding each centrifugal pump
It is required for before startup pouring water in pump housing inner chamber and inlet channel and consuming substantial amounts of manpower, it is necessary at water inlet pipe mouth, be installed the end
Valve.Bottom valve, the one of check-valves, play the water backflow prevented in pump, keep water level in pump to be in the effect of the state of filling, typically
It is arranged on the end of inlet channel.
Because being affected by microorganism in water source, algae, impurity etc., cause filter screen part to silt up, bottom valve poorly sealed, go out
The phenomenon now leaked；Or because bottom valve encapsulant is aging, poorly sealed, the phenomenon leaked occurs, leads to centrifugal pump discharge opeing
Amount minimizing does not even absorb water.There is this situation in centrifugal pump, it is necessary to shuts down, bottom valve is taken out from water, overhauls or change, and
Clean filter screen.Owing to bottom valve is under water, the farmland that particularly irrigation water capacity is big, pond liquid level declines fast, for ensureing water inlet
Mouth is under liquid level for a long time, it is necessary to add the underwater penetration of steamer connection.If bottom valve needs maintenance, filter screen to need to clean, it is necessary to
The water inlet pipe going deep into pond is pulled down, bottom valve could be taken out, due to the dismounting of Heavy Weight, water inlet pipe and bottom valve and reinstall
Wasting time and energy, maintenance cost is high.
Water borne type bottom valve is arranged on bottom valve on the water surface, although maintenance is convenient, but the loss of flood peak is big.Accordingly, it would be desirable to improve
Existing submersible bottom valve device solves the maintenance issue of bottom valve.
Summary of the invention
It is an object of the invention to disclose a kind of convenient disassembly, staff can stand at the bottom of the platform float type overhauled on platform
Valve gear.
The technical scheme is that on the basis of conventional centrifugal pump submersible bottom valve installation method, bottom valve with
One joint flexible pipe is set on the pipeline between centrifugal pump；Tie up the flange above bottom valve with rope or iron chains again and a buoyancy aid connects
Connect.
Described flexible pipe, is to have certain elasticity, it is possible to the flexible pipe of alternating bending, can be rubber tube or plastic cement
Flexible pipe, such as fabric enhancement mode rubber tube, PVC steel wire tube etc..Overhaul and improve sealing, flexible pipe and water inlet pipe for convenience
Use the connected mode of flange screw thread.
Buoyancy aid, i.e. floats on the object of liquid surface, as long as the buoyancy of its generation submerged in water can afford to drag fills
The water inlet pipe of water and bottom valve, there is certain corrosion resistance, can use.Available commercially available hollow plastic ball shape thing, box like thing,
Tub or their multiple compositionss are as buoyancy aid.But some water-saving irrigation projects are in mountain area, and buoyancy aid raw material is not easy
Buy.Therefore, buoyancy aid of the present invention, is to be passed through by several pvc pipes, multiple tee pipe fitting, multiple pipe cap and multiple flange
Bonding and flange screw thread the mode of glue assembles, it is desirable to mounted tubing and pipe fitting are substantially in a plane, knot
Structure is symmetrical or near symmetrical, and people can steadily stand on the buoyancy aid being placed on the water surface.
The platform float type bottom valve device operation principle of the present invention is: buoyancy aid is by about buoyancy, and the buoyancy of generation can
Holding up water inlet pipe and bottom valve, when field irrigation, water level in water pool constantly declines, and when water feeder pumps into water, water level in water pool is continuous
Rising, under the effect of buoyancy aid and flexible pipe, bottom valve can upper and lower swing, and bottom valve has been at below liquid level (unless tank water
Position is the lowest or water is drained), bottom valve keeps constant (so bottom valve need not go deep into very much in liquid level) with the distance of pond liquid level.Work as the end
Valve breaks down when needing maintenance, and staff can go to buoyancy aid along water inlet pipe from bank, pond, it is only necessary to bottom valve and
The flange that water inlet pipe connects is pulled down, and the most easily takes off bottom valve.The installation of bottom valve is the most very convenient.

Detailed description of the invention
Embodiment
As shown in Figure 2, Figure 3 and Figure 4, on the pipeline between bottom valve 2 and centrifugal pump, install by the way of flange screw thread
One joint rubber flexible pipe 3；One of iron chains 4 is buckled on the flange being connected with bottom valve 2, and the other end of iron chains 4 is buckled in the method for buoyancy aid 1
Lan Shang, constitutes platform float type bottom valve device.
The assemble method of buoyancy aid 1 as it is shown on figure 3, pvc pipe, tee pipe fitting, pipe cap and flange are all PVC material, therefore it
Method of attachment between is carried out according to the connected mode of PVC, pipe fitting, and PVC connection member all uses the side that glue is bonding
Formula, uses the connected mode of screw thread between flange plate, rubber sheet gasket to be placed between flange plate, improves the airtight of linkage interface
Property.All of tubing should align as far as possible and be in approximately the same plane after installation process and installation with pipe fitting, the most attractive in appearance,
The platform formed is steady again, and personnel conveniently carry out the work on platform.
Compared with conventional submersible bottom valve device (see figure 1), the platform float type bottom valve device of the present invention need not handle
Bottom valve gos deep into the position that pond liquid level is the deepest.The buoyancy that the platform float type bottom valve device of the present invention utilizes buoyancy aid to produce holds up.
Above example is the preferred version of the present invention, and unrestricted.In the know-why of the present invention, can to more than
Technical scheme described in embodiment is modified, or replaces portion of techniques feature therein on an equal basis, these amendment or
Displacement, both falls within technical scheme scope.
