Abstract
The utility model discloses a dust unloading ball valve, which comprises a valve body, a valve seat, a ball body and a valve rod, wherein the valve body is an integrated structure, and the inner and the outer sides in a sealing surface of the valve seat are provided with a G-shaped mortar removing device. The dust unloading ball valve has simple structure, convenient installation, and safety and reliability.
Description
Technical field
The utility model relates to a kind of ball valve, the key equipment of specifically a kind of metallurgy high furnace dust pelletizing system, thermoelectric blast furnace dedusting system etc., Unloading ball valve.
Background technique
Existing Unloading ball valve is because foreign material such as grey matter are infected with spheroid, causes poorly sealedly, or sealing surface of seat and sphere be because of the foreign material deposition blocks, and causes Unloading ball valve relatively to be lacked working life and often causes damping down, stopping production.
The model utility content
The purpose of this utility model is for providing a kind of installation simply, and is easy to operate, the Unloading ball valve of long service life.
The technological scheme that realizes the foregoing invention purpose is as follows:
A kind of Unloading ball valve comprises valve body, valve seat, spheroid and valve rod, and wherein said valve body is a monolithic construction, and the inside and outside both sides of the sealing surface of described valve seat are provided with G shape and remove Mortaring device.
Described spheroid is a hemisphere, and described hemispheroidal ball mouth edge is edge of a knife structure.
Be equipped with helical spring or belleville spring between the behind of described valve seat and the valve seat end cap.
Be connected for maze-type structure between described valve seat and the valve body.
Described valve rod is provided with the anti-mechanism that blows out, and describedly anti-ly blow out mechanism and comprise the snap ring of being located on the valve rod, the filler end cap of snap ring top, the gland of the filler of the charge end side of covering and filler top, described gland is connected with valve body by bolt.
Described valve rod is provided with anti-fouler, and described anti-fouler is for having the greasing hole of sensible valve rod on valve body, and described greasing hole is provided with grease pouring valve.
The utlity model has install simple, easy to operate, long service life, characteristics such as safe and reliable.
Description of drawings
Fig. 1 cuts open figure for structure of the present utility model;
Fig. 2 is the A portion enlarged view of Fig. 1;
Fig. 3 is the enlarged view of the B portion of Fig. 1;
Fig. 4 is the anti-enlarged view that blows out portion of mechanism of Fig. 1.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of Unloading ball valve comprises valve body 1, valve seat 2, spheroid 3 and valve rod 4, and wherein said valve body 1 is a monolithic construction, and the inside and outside both sides of the sealing surface of described valve seat are provided with G shape and remove Mortaring device 10.
This removes Mortaring device and act as: both sides are provided with G shape and remove Mortaring device inside and outside the sealing surface of valve seat, when valve opening and closing, can strike off the foul 11 that is bonded on the ball seal face automatically, the cleaning that keeps the ball seal face, assurance spheroid and valve seat are well fitted, and make valve have excellent sealing performance all the time.
Described spheroid is a hemisphere, and described hemispheroidal ball mouth edge is edge of a knife structure.
This edge of a knife structure also can be wiped the booty of sealing surface of seat simultaneously off, removes Mortaring device with G shape, can strike off the bonding foul mutually automatically so sealing surface of seat and sphere can the foreign material deposition not block.
Be equipped with helical spring or belleville spring 12 between the behind of described valve seat and the valve seat end cap.
Be connected for maze-type structure between described valve seat 2 and the valve body 1.Have two road seal rings 13,14 like this between valve body and the valve seat at least, impurity etc. can not enter in the spring like this, effectively improves spring life, and spring plays key and does usefulness in the middle of valve, effectively protect spring, also just improves life of valve.
Described valve rod is provided with the anti-mechanism that blows out, and describedly anti-ly blow out mechanism and comprise the snap ring of being located on the valve rod 6, the filler end cap 7 of snap ring top, the gland 9 of the filler 8 of the charge end side of covering and filler top, described gland is connected with valve body by bolt.So not can along with the increase of pressing more valve rod rise and blow out.
Described valve rod is provided with anti-fouler, and described anti-fouler is for having the greasing hole of sensible valve rod on valve body, and described greasing hole is provided with grease pouring valve 15.Increased grease pouring valve, thus the anti-dirt of greasing.
