Description
Technical field
The utility model relates to a kind of float valve, particularly a kind of float valve of controlling the water container water level.
Background technique
Float valve is the vitals of water container water level control, and its quality is directly connected to the speed of water and whether can produces the phenomenon of metalling run out; Domestic for this reason many entity and individual have carried out many improvement preferably to float valve, and declared many patents, but understood, still existed under the condition of identical bore from existing public technology, poor sealing performance when water-outlet quantity is big, water-outlet quantity is with regard to little problem during good airproof performance.Therefore, it is big to develop a kind of not only water-outlet quantity, and the float valve of good seal performance, is extremely urgent problem.
Summary of the invention
For overcoming the above-mentioned disadvantage that existing float valve exists, problem to be solved in the utility model provide a kind of simple and compact for structure, easy for installation, water-outlet quantity big, the piston type large flow ball float valve of good seal performance, long service life.The technological scheme that its technical problem that solves the utility model adopts comprises valve body, valve gap, lever, ball float, valve gap is fixed on the valve body, ball float and lever are fixed, valve body is provided with water intake and main water outlet, be provided with piston and spring in the chamber of described valve body, piston is provided with piston packing ring, on the valve body of water inlet oral-lateral, be provided with step, piston is provided with the seal ring that cooperates with step, piston end face is provided with into water aperture, valve gap is provided with the ostium excurrens that communicates with valve chamber and pays the mouth of a river, the center hole of valve gap is provided with mobilizable slide block, and slide block is provided with the seal washer that cooperates with ostium excurrens, is hinged with rocking arm on the valve gap; an end and the lever of rocking arm are fixed, and the other end is arranged on the pilot hole of slide block.
For the ease of pistons work guiding and big flow water outlet, be fixed with empennage on the described piston end face.
In order to prevent that impurity from stopping up the water inlet aperture, the water inlet aperture of described piston is provided with filter screen.
In order to adapt to the needs that different water containers are installed, the threaded coupling of described valve body is provided with set screw nut.
After adopting said structure, during this float valve work, because the suffered pressure difference in piston two ends, piston is pushed open by hydraulic pressure, and straight-through between water intake and the main water outlet, it is little to go out water resistance, also have a small gangs of water to flow in addition from the water inlet aperture of piston, flow out from the mouth of a river of paying of valve gap, therefore, water flow maximum under the condition of identical bore; Behind the water container filling up water, ball float is held up and is driven rocking arm promotion slide block and shut ostium excurrens, the inboard pressure that produces of piston, add the effect of spring force, promote piston reset and block current, because the sealing surface of piston inner seal ring is greater than the piston sealing surface of intaking, the piston back pressure is all the time greater than the pressure of current to piston, so dead no matter hydraulic pressure has much pistons reliably current to be closed; Have advantages such as compact structure is reasonable, easy for installation, water-outlet quantity big, good seal performance, long service life.
