Description
Technical field
The utility model relates to industrial valve technical field, is specifically related to a kind of butterfly valve of high sealing performance.
Background technique
Due to valve often keying can cause between valve rod and valve body fitting surface wearing and tearing to cause matching gap excessive, under internal pressure effect, fluid flows to filler chamber by gap, accelerate filler aging and flow out filler chamber, cause and leak, secondly, the long-term pressurized of seal ring on valve plate and be subject to washing away change after damaging inconvenient.
Model utility content
For the deficiencies in the prior art, the utility model provides a kind of butterfly valve of good airproof performance.
To achieve these goals, the utility model solves the technological scheme that its technical problem adopts: a kind of butterfly valve, comprise valve body, valve rod, butterfly plate, operation equipment, butterfly plate plate face is arranged on the passage central authorities of valve body perpendicular to the passage axis of valve body and rotation, butterfly plate is in transmission connection by valve rod and operation equipment, described valve rod hypomere portion is provided with sliding sleeve and is socketed in valve body bottom, valve rod underpart is socketed with thrust ring or thrust bearing, valve body bottom is by bottom seamless welding, described valve rod epimere position is also provided with sliding sleeve, and be socketed in valve body top, valve body top offers filler chamber around along valve rod, the in-built filler that fills up of filler chamber, filler chamber's oral area compresses by packing press ring, the madial wall of packing press ring, outer side wall coordinates with valve rod and filler chamber's inwall respectively, and between fitting surface, be provided with some seal rings, the butterfly plate one side outward edge that described valve rod stage casing is fixedly connected with is socketed with butterfly plate seal ring, butterfly plate seal ring closely connects by screw and trim ring.
Furtherly, the cylindric sliding sleeve that described sliding sleeve is hollow, is Cu alloy material.
The shaftgear of operation equipment and motor is in transmission connection, and motor is electrically connected with controller, and controller is electrically connected with remote server by wireless, works by remote server control controller.Can pass through telecontrol, be applicable to inconvenient field control, intelligent degree improves.
Controller is also electrically connected with Internet of Things, by the remote terminal control controller of Internet of Things.Butterfly plate is wrapped with anticorrosive PTFE layer, is compounded with anticorrosive PTFE layer in the passage of valve body.Can implement to control by Internet of things system and other intellectualizing system like this.
Operation equipment is that handwheel and worm gear, worm component are in transmission connection, and is flexibly connected between handwheel and worm screw.Handwheel can be taken off, prevent inoperative personnel operation, there is anti-theft feature simultaneously.
The side that butterfly plate is positioned at valve inleting water mouth is provided with the low spherical surface of middle high surrounding.Can reduce the impact force of current.
Butterfly plate seal ring is made up of soft T V-shaped ring both sides multilayer stainless steel sheets.Adopt hard seal wear-resistant good.
Butterfly plate is double layer construction, and in double layer construction, is provided with elastic interlayer.Can reduce current cause each element on valve body damage to the impact of valve plate.
Also comprise valve seals, the cross section of valve seals is inverted trapezoidal, and the groove that seal ring is installed on valve body is accordingly also inverted trapezoidal.Like this, in installation and using process, seal ring difficult drop-off.
The beneficial effects of the utility model: this butterfly valve integral sealing is good, rational in infrastructure, can not produce friction gap affects sealability between valve rod and valve body.
