Description
Technical field
The utility model belongs to valve field, relates to a kind of backwater Filtering ball valve.
Background technique
General ball valve comprises two ends and is respectively the valve body of feed-water end and waterexit end and is arranged at valve body inner spherical core, and feed-water end and waterexit end lay respectively at the both sides of ball core, and ball core is connected with the valve rod in switch knob and is used for closing or opening water route.But when opening water route, the impurity in the current in pipeline and iron filings can flow to waterexit end along with current from feed-water end, and by daily life drink, certain harm can be caused to human body, and too much impurity due to long-term blocking can block pipeline.
Therefore, in order to the improvement to the problems referred to above, filter screen is provided with between the feed-water end of existing ball valve in valve body and waterexit end, foreign material or larger particle is made not to enter waterexit end, but because iron filings slightly little in water effectively can not filter iron filings at common filter screen, and the outflow of iron filings can cause certain harm to human body, and also can the impeller in water pump closely be caused damage.
Summary of the invention
The purpose of this utility model is the problems referred to above existed for prior art, proposes the backwater Filtering ball valve of the simple iron shaving adsorption apparatus of a kind of structure.
The purpose of this utility model realizes by following technical proposal:
A kind of backwater Filtering ball valve, comprise two ends and be respectively the valve body of feed-water end and waterexit end and the ball core be arranged in valve body and valve rod, described feed-water end and waterexit end lay respectively at the both sides of ball core and formed water cavity between the inherent waterexit end of valve body and ball core, it is characterized in that, described valve body sidepiece is provided with the screen pipe be connected with the water cavity excessively of valve body and the connecting tube be connected with the waterexit end of valve body, the end of described connecting tube is connected with the sidepiece of screen pipe, the water cavity of crossing of described valve body is connected by screen pipe and connecting tube with waterexit end, filter screen is provided with in described screen pipe, the end of described screen pipe is bolted with pressure cap, described pressure cap inside bottom is fixed with magnet.
When connecting pipeline and having current to flow into, open switch knob, the valve rod connected in switch knob drives ball core in opened condition, flowing water flows into through feed-water end and flows out through waterexit end by flowing to connecting tube after the filter screen filtration crossing in the screen pipe that is connected of water cavity of valve body again, because some less iron filings can flow in valve body along with current, therefore, the magnet that the iron filings carried when current lead to filter screen can be arranged in pressure cap adsorbed, the blocking of pipeline can be prevented, and effectively avoid the harm that in current, iron filings bring to human body.When closing switch handle, the valve rod connected in switch knob drives ball core to be closed state, current will be blocked in feed-water end port, pressure cap on the screen pipe be arranged in valve body sidepiece cavity can be backed out, other impurity in cleaned filter screen, and the iron filings that the magnet in pressure cap adsorbs are cleared up.Achieve easy to operate, and cleaning iron filings and other impurity effective.
In above-mentioned backwater Filtering ball valve, described screen pipe has the annular convex shoulder of protrusion near the above-mentioned one end madial wall crossing water cavity, the madial wall of described pressure cap has shoulder block, and one end of described filter screen is resisted against on annular convex shoulder, and the other end is resisted against on the shoulder block of pressure cap.
When tightening pressure cap, filter screen can be clamped and isolate screen pipe and connecting tube, avoids the impurity in flowing water directly to enter waterexit end, can impurity effectively in isolated water.
In above-mentioned backwater Filtering ball valve, described feed-water end port threads is connected with bonnet, and this bonnet is connected with union away from the threaded one end of above-mentioned feed-water end.
When there being current to flow out in pipeline, fast the feed-water end being connected with bonnet being communicated with by union, and controlling current by switch knob, by connecting fast, can clear up ducted impurity.
In above-mentioned backwater Filtering ball valve, described magnet is that the hydropexis of flat blend compounds is in pressure cap inside bottom.Because the iron filings in current flow to the waterexit end communicated with connecting tube after the filter screen filtration in chimney filter, when being adsorbed through the pressure cap with magnet, can effectively clear up iron filings in water.
Compared with prior art, this backwater Filtering ball valve has the following advantages:
1, when connecting pipeline and having current to flow into, open switch knob, flowing water flows into through feed-water end and flows out through waterexit end by flowing to connecting tube after the filter screen filtration crossing in the screen pipe that is connected of water cavity of valve body again, iron filings entrained in current can by the magnet inside pressure cap, and filter screen can filter other impurity in water.
2, when closing switch handle, pressure cap and filter screen can be taken off and clear up, achieve easy to operate and absorption iron filings good impurity removing effect.
3, when there being current to flow out in pipeline, fast the feed-water end being connected with bonnet being communicated with by union, and controlling current by switch knob, by connecting fast, can clear up ducted impurity.
