Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
The embodiment of the electric flange type butterfly valve is as follows:
referring to fig. 1-5, an electric flange type butterfly valve includes a valve body 1, an anti-drop chute is disposed on an inner wall of the valve body 1, an electric actuator 2 is installed on a top of the valve body 1, a valve 3 is installed inside the valve body 1, a supporting tube 4 is inserted into a right side of the valve body 1, anti-drop blocks are disposed on outer sides of the supporting tube 4 and a driving tube 7, and the anti-drop blocks are slidably connected in the anti-drop chute to prevent the supporting tube 4 and the driving tube 7 from being separated from the valve body 1.
Pull out stay tube 4 from valve body 1, then peg graft stay tube 4 in the connecting tube, stay tube 4 makes the preliminary high-speed joint of electronic flange formula butterfly valve, need not to continue to lift this moment, can carry out flange joint, simple to operate.
The left side of valve body 1 is pegged graft and is had drive tube 7, the right side fixedly connected with reset spring 8 of drive tube 7, the back fixedly connected with piston rod 9 of drive tube 7, six groups are no less than to piston rod 9, and piston rod 9 sliding connection is in storage hole 5, storage hole 5 has been seted up to the inner wall of valve body 1, storage hole 5 is no less than six groups, and the cross section of the half section in the left side of storage hole 5 is the semicircle, the cross section of the half section in the right side is the whole circle, when not influencing drive tube 7 gliding, can save liquid, orifice 6 has been seted up on storage hole 5's right side, orifice 6's radius is less than storage hole 5, and form certain contained angle between orifice 6 and the storage hole 5, and to the inside slope of valve body 1, make liquid can spout on valve 3 edges, and then wash valve 3.
Rivers promote the relative valve body 1 of drive tube 7 and move left, drive tube 7 drives piston rod 9 and slides, piston rod 9 makes storage hole 5 breathe in, inhale liquid in the storage hole 5, when valve 3 need be closed, rivers reduce, drive tube 7 resets under reset spring 8's effect, drive tube 7 drives piston rod 9 and resets, the liquid of the storage in storage hole 5 is extruded through orifice 6 to piston rod 9, orifice 6 washes the sealed edge of valve 3, thereby prevent that mud or solid medium from blockking that valve 3 from closing.
