Abstract
The utility model discloses a tee junction bottom valve floating on the water and comprising a valve body, which is characterized in that: a water inlet and a water outlet are arranged on the valve body, and the water inlet and outlet are respectively fixed with a suction pipe and a flange connected to a pump; wherein, at the valve port opposite the water inlet is provided with a sealing valve cap through the flange, and the sealing valve cap is connected with a valve stem guiding pipe of the hollow cylinder shape, and the valve body is provided with a freely falling body with a valve stem that seal and block the valve plate at the water inlet of the valve body, while the upper end of the valve stem is positioned in the guiding pipe. The utility model has the advantages of simple manufacture, low cost and long service life as well as reduction of maintenance load and cost and obvious economic effect. In addition, the utility model has solved the problem that the bottom valve and the armored water suction hose can not be maintained remaining in the water, thus improving the working environment for the maintainers so at to save labor, in doing so not only having reduced the labor intensity, but also greatly improved working efficiency as well as obviously promoting the water discharging efficiency.
Description
Technical field:
The utility model relates to a kind of drainage, relates in particular to a kind of Three way type bottom valve waterborne that is used for pump drainage water.
Background technique:
The dead-weight bottom valve at present domestic in drainage, that pump foot valve adopts cast iron to make more.Its valve body is submerged in the water fully, links to each other with the pump sump end by armored hose or steel pipe.When using the bottom valve of cast iron making, because bottom valve is installed under water, usually cause valve block poorly sealed, water pump suction pipe can't drain into vacuum state, influences water pump and normally starts.And because maintenance inconvenience, bottom valve inside is often stopped up by mortar and the foreign material that a part precipitates, and causes drainage performance to reduce, and stops up when serious, and bottom valve can't be worked.After the bottom valve that cast iron is made damages, must there be several attendant's plunge that bottom valve is together carried away the water surface together with the armouring water suction hose, can carry out maintenance process, therefore this bottom valve is in draining, exist easily leak, fragile, under water maintenance difficulty, poor safety performance, influence shortcoming such as drainage performance, brought inconvenience to real work.
Summary of the invention:
In order to overcome the above-mentioned shortcoming that present pump foot valve exists, the purpose of this utility model provides and a kind ofly can satisfy water pump to the vacuum requirements of drawing water, can prevent from again to leak, overhaul easily, guarantee safety, reduce service worker labor intensity, improve the Three way type bottom valve waterborne of working environment.
The technical solution of the utility model realizes in the following manner:
A kind of Three way type bottom valve waterborne, it comprises water intake, water outlet on valve body, the valve body, on water intake, water outlet, be fixed with respectively and suction sleeve, water pump flange connecting, wherein, connect a sealed valve cap at the valve port relative by flange with water intake, be connected with the stem guiding pipe of an open circles pillar on sealed valve cap, place the valve plate of the freely falling body shutoff valve inleting water mouth of a band valve rod in valve body, the valve rod upper end is positioned at guide pipe.
Be connected with inner convex platform on the inwall of valve body water sucking mouth, valve plate is by contacting the shutoff water intake with the convex table top.
Also logical anti-loosening nut, stationary platen are equipped with the sealing offset plate with its sealing of better realization on the screw rod below the valve plate.
The working principle of this Three way type bottom valve waterborne:
When water pump was opened, the ponding of sump entered in the suction sleeve through suction sleeve lower end filter screen, and the sealing damper of bottom valve waterborne is opened under the centrifugal suction of barometric pressure and water pump, enters water pump, discharges along discharge pipe line.When water pump shut down, bottom valve waterborne relied on the effect of its interior sealing damper deadweight and backwater impulse force, and sealing damper is hurtled down, and the water in blocking-up water pump and the horizontal suction sleeve flows into sump.At this moment become vacuum state in the suction sleeve of bottom valve waterborne bottom, the sump water surface is in the barometric pressure effect, makes to remain in the suction sleeve of bottom valve waterborne bottom to be full of water state.Thereby pour water in the time of must growing water pump before having avoided that water pump is each and starting, the operating time even the operation of vacuum pumping.
Good effect of the present utility model is:
(1), bottom valve waterborne adopts the A3 steel to do, make simple, cost is lower, more sturdy and durable than the bottom valve that cast iron is made, not fragile, the life-span is long.Bottom valve waterborne need not changed after installing, the general replacing seal rubber pad that only needs.Thereby reduced maintenance load and reduced maintenance cost, remarkable in economical benefits.
(2), bottom valve reliable performance waterborne, anti-impact force is strong.Even have a power failure suddenly, in the water gate valve on foreign material influence and the water pump, when the safety check working state is unreliable; also can moment the closing seam flashboard; water pump is played a good protection, make pump housing impeller avoid suffering high pressure water impact, effectively prolonged the working life of water pump.
(3), adopt bottom valve waterborne after, just can avoid bottom valve and armouring water suction hose are carried away the phenomenon that the water surface can overhaul, maintenance man only need one people gets final product.This has not only reduced labor intensity, has also improved work efficiency greatly.
(4), bottom valve Maintenance free personnel underwater work waterborne, disease such as can effectively check the skin infection that contains mordant swallet the attendant is produced, fester.
(5), adopt bottom valve waterborne after, drainage efficiency obviously improves.
(6), bottom valve reliable performance waterborne, starting mode of pump is convenient, has strengthened the emergency repair guarantee of water pump.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
As seen from Figure 1: it comprises on valve body 1, the valve body 1 water intake, water outlet, on water intake, water outlet, be fixed with respectively and suction sleeve, water pump flange connecting 2, wherein, connect a sealed valve cap 3 at the valve port relative by flange with water intake, on sealed valve cap 3, be connected with the stem guiding pipe 4 of an open circles pillar, place the valve plate 9 of the freely falling body shutoff valve inleting water mouth of a band valve rod 5 in valve body, valve rod 5 upper ends are positioned at guide pipe 4.
Be it can also be seen that by Fig. 1: be connected with inner convex platform on the inwall of valve body water sucking mouth, valve plate 9 is by contacting the shutoff water intake with the convex table top.
It can also be seen that by Fig. 1: also sealing offset plate 8 is housed with its sealing of better realization on the valve rod below the valve plate 9 by anti-loosening nut 6, stationary platen 7.
Bottom valve waterborne is installed between horizontal suction sleeve of water pump and the vertical suction sleeve, is positioned on the sump water surface.Use connecting bolt that bottom valve one end waterborne and vertical suction sleeve are connected and fixed, the horizontal suction sleeve of the other end and water pump is connected and fixed, and it is fixing that horizontal suction sleeve must adopt rope to hang.
Enter in the suction sleeve for reducing foreign material, can add a filter screen in the vertical suction sleeve bottom in being sunken to sump.
