Owing to adopt the integral structure of above-mentioned switching ball, safety check and pressure regulator valve, can prevent aqueous reflux, and make the pressure at valve export place keep constant relatively, prevent valve after watering equipment destroyed by high pressure, thereby guaranteed the safety of watering equipment behind the valve effectively.
Described ball valve can be fixed in the water inlet of described valve body by clamping nut; Its effect is that the operation ball valve is reliable and stable.Corresponding to the ball valve position, the valve body bottom opening disposes blocking cap, so that the water of emptying the inside.
Described pressure regulator valve preferably includes a Safety valve body, and a side mouth of an end of this Safety valve body and described valve body is tightly connected; Described safety lever is arranged on the other end of described Safety valve body; This safety lever device is provided with an emergency valve seat between a side of sealing base and the interior hole end surface of described Safety valve body in a gasket base; Described Safety valve body opposite side is provided with an endoporus conical surface, and described safety check is arranged between this hole conical surface and the described ball valve; Described safety check is connected with described water outlet.Described Safety valve body bottom is provided with discharge opening.
Its function of above structure is that water can be discharged from the discharge opening of pressure regulator valve when the pressure that water intake pressure is set greater than pressure regulator valve, to reduce the pressure in the pipeline, guarantees the safety of watering equipment behind the valve.
Described Safety valve body outside can dispose a shell, and an end of this shell is connected with the end face of described valve body.Its effect is to make the pressure regulator valve stable operation.
Described safety lever can place the pressure regulating spring of band spring seat, and the other end of this spring contacts with gasket base; Described spring seat interior edge face and described Safety valve body interior edge face are tightly connected.
As further improvement of the utility model, the outer end of described safety lever is connected with the pressure regulator valve cap of band jump ring.Regulating the setting pressure of pressure regulator valve easily,
The utility model adopts the integrated design of ball valve, safety check and pressure regulator valve, compared with prior art, its advantage is that it is simple in structure, and can regulate gets the pressure at valve export place, and can keep constant relatively, destroyed by high pressure with watering equipment after preventing valve; In addition, can also prevent aqueous reflux; Thereby stability in use and reliability are better.
