Abstract
The utility model discloses a butterfly rotary two-way double-break valve which comprises a valve bonnet, a valve stem, a valve seat, valves, a rotary handle, a screw and sealing rings. Four liquid inlet and outlet holes are respectively formed in the valve bonnet and a valve body, corresponding ports are respectively arranged on the valve bonnet and the valve body, the valve bonnet covers the valve seat and is connected with the valve seat by the screw, a space between the valve bonnet and the valve body is sealed by the corresponding sealing ring, the valve stem is inserted in the valve seat, is sealed by the corresponding sealing ring and can rotate at an optional angle, the two valves are arranged on the valve stem and respectively correspond to two inlet and outlet pipelines, the corresponding sealing rings sleeve the two valves, and the valves are fixed onto the valve stem by the aid of rivets and can be driven by the valve stem to rotate, so that the inlet and outlet holes of the butterfly rotary two-way double-break valve can be simultaneously closed and opened under the control, the rotary handle is arranged at the end, which is positioned on the outside of the valve seat, of the valve stem, is connected with the valve stem by a flat key and can drive the valve stem to rotate. The butterfly rotary two-way double-break valve has the advantages of reasonable structure, convenience in operation, high sensitivity during operation, low cost and the like.
Description
Technical field
The utility model relates to a kind of liquid valve, is specifically applied to feeding pipe and discharge nozzle simultaneously open-minded, the butterfly double on and off valve of simultaneously closing.
Background technique
The valve major part using is at present only applicable to a kind of turnover of medium, and the method that be applied to two or more medium turnover has: the one, adopt valve group, and the 2nd, adopt multiple-way valve. valve group is mainly divided into two valve groups, three valve groups and five valve groups.They are to combine formation with several single valves, and structure is simpler, but too heavy, operation is trouble.Multiple-way valve is by a valve body, has multiple import and export on valve body, and its advantage is can multi-purpose valve, and a valve can replace multiple valves, connects multiple pipelines, and simple in structure, reliable.
Chinese patent CN2514184Y has announced a kind of four-way change-over valve, it comprises valve body, valve rod, butterfly plate, Gland, upper and lower support flange and metal (upper, there are four sealing surfaces at the step of endoceliac four protrusions of valve, form four sealing pairs with butterfly plate sealing surface, six faces of valve body have six flanges, and butterfly plate is contained on valve rod, the valve function that this patent is described is more reasonable, but the defects such as structure is more complicated, and cost is high, poor sealing; Chinese patent CN2563383Y has announced a kind of valve, it comprises four flanged pipes that connect on valve body, valve plate and valve body, valve body is cylindric, in valve body, there is rectangle valve plate, the axle at valve plate center and the dead in line of valve body, the valve function that this patent is described is more reasonable, but its poor sealing, the defects such as complex structure.
Two position four-way valves that use on market now, ubiquity complex process, the defect such as cost is high, poor sealing.
Model utility content
The utility model provides and is applied to feeding pipe and discharge nozzle is simultaneously open-minded, the butterfly double on and off valve of simultaneously closing.For achieving the above object, the utility model provides following technological scheme.
A kind of butterfly rotation double on and off valve, comprise valve gap, valve rod, valve seat, valve, swing handle, screw and seal ring, on described valve gap and described valve body, there are respectively two turnover liquid material holes and corresponding interface, described valve gap covers on described valve seat, described valve rod is inserted in described valve seat, two described valves are housed corresponding respectively at two in-and-out pipe on described valve rod, described valve rod is equipped with a swing handle in one end of the outside of described valve seat.
Butterfly rotation double on and off valve described in the utility model, uses screw attachment, and seals with seal ring between the two between described valve gap and described valve end.
Butterfly rotation double on and off valve described in the utility model, described valve is arranged on described valve rod with rivet, and on valve, cover has stuffing box gland.
Butterfly rotation double on and off valve described in the utility model, connects with flat key between described valve rod and described swing handle.
Adopt the beneficial effect of above technological scheme to be: valve body is box typed structure, compact structure; Valve rod adopts hole shaft clearance to coordinate with valve seat, good seal performance; Its sensitivity of break-make of rotary control valve by valve rod is better.
