Description
Technical field
The utility model relates to valve, particularly relates to change-over valve.
Background technique
Stop valve, also known as pipe valve valve, belongs to forced seal formula valve, so when valve closing, must apply pressure, do not leak with forced seal face to flap.When medium is by when entering valve below flap, the resistance overcome required for steering force, be the frictional force of valve rod and filler and the thrust produced by the pressure of medium, the power of the force rate valve opening door of closing valve is large, so the diameter of valve rod wants large, otherwise the fault of valve rod bending can be there is.The open-shut device of stop valve is the flap of stopper, and sealing surface is plane or tilted conical surface, and flap is along the center line moving linearly of valve seat.The forms of motion of valve rod, (adopted name: dark bar), also has lifting rotation rod-type to can be used for controlling the flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.Therefore, such stop valve valve that dams is suitable as and cuts off or regulate and throttling use very much.Valve rod due to such valve open or shutoff stroke relatively short, and there is cutting function very reliably, again due to the change of valve seat port and the stroke direct proportionality of flap, be very suitable for the adjustment to flow.A lot of regions fighting terminal water supply pressure is lower at present, and fire-fighting water often range is inadequate, and lift is shorter, is difficult to play larger effect when there is the condition of a disaster.
Model utility content
The technical problems to be solved in the utility model is that existing fighting terminal water supply pressure is lower, fighting terminal water and urbanite water consumption is combined by stop valve for this reason, provides a kind of two-bit triplet commutation stop valve.
The technical solution of the utility model is: two-bit triplet commutation stop valve, it comprises intake pipe, described intake pipe is communicated with the first outlet conduit and the second outlet conduit respectively, the first connecting port that described intake pipe and the first outlet conduit connectivity part are formed and the second concentric same footpath of connecting port that intake pipe is formed with the second outlet conduit connectivity part, described second outlet conduit is also provided with the bypass duct with the first connecting port and the concentric same footpath of the second connecting port, the valve rod that in described bypass duct, adaptive oriented intake pipe extends, described valve stem end is connected with the flap that can move linearly between the first connecting port and the second connecting port, described flap external diameter and the first connecting port and the second connecting port suitable.
The actuator of actuating valve lobe movement is provided with outside bypass duct described in such scheme.
The beneficial effects of the utility model are using the first outlet conduit as resident living water pipeline, and the second outlet conduit is as fire-fighting water pipeline, and flap is between the first connecting port and the second connecting port at ordinary times, make resident and fire protection pipeline all have water to use.When the condition of a disaster fire-fighting water hydraulic pressure occurring being not enough, flap is urged to the first connecting port by actuator, and between intake pipe and the first outlet conduit, path is truncated, and intake pipe is communicated with formation path with the second outlet conduit, ensures that fighting terminal supplies water with all strength.
