The annexation of working principle and each parts: be described as follows with reference to Fig. 1, Fig. 2 and Fig. 3:
One. parts annexation
The valve of this model utility is coal dust operating mode Special wear-resistant ball valve, comprises valve body 1 for upper dress formula structure, carries secondary valve gap 2, main valve lid 5 and spool 11; Hex head bolt 4 and spring washer 3 (playing retaining effect) link together major and minor valve gap (2,5) and valve body 1; O grommet type seal circle 6 makes to reach seal action between valve body and major-minor valve body; Valve seat lasso 7 prevents valve seat from entering coal dust behind, and such valve seat there will not be and spool locking phenomenon; Butterfly spring 8 plays valve seat and spool pretension seal action; O type valve seat insert 9 prevents coal dust from entering valve seat 10 butterfly spring chamber 8 behind from valve body chamber 1.Valve seat 10 is held spool tightly and is sealed under the effect of butterfly spring 8; Spool 11 is core components of valve, U-shaped structure, and spool in the on-state, makes medium in valve pocket, hold vortex type flowing, washes away the precipitation coal dust in valve pocket, make spool can not be subject to the long-term coal dust precipitated stuck; The structure of O RunddichtringO 12 is with valve seat insert 9; Bearing (13,14) is fixed on spool in the groove of valve body and valve gap, makes spool in switching process, play good lubrication, increases working life, reduces open and close torque; Valve gap 15, after internals assembling, valve gap is loaded by upper valve shaft, is tightened by bolt 16 and valve body; Lower filler 17, middle filler 18, upper filler 19 is T-type structure, and after itself and filler pressing sleeve 20 gland load, top loads No. 21 butterfly springs, and this structural type makes filler be in Pre strained state always, reaches better sealing effect.Conventional construction is by bolt tightening Gland, and under Long-Time Service state, filler easily leaks.
Butterfly spring gland 22 is tightened on valve gap by bolt 23.Bolt 24 is fixed on support 26 on butterfly spring gland.Valve rod 25 connecting sleeve is connected between valve rod and final controlling element 29; Link (27,28) makes support and final controlling element link together.
Two. working principle
This valve solves the long-term in use coal dust of pipeline by special structure and is deposited in the phenomenon of stuck spool in valve pocket.
Valve opening and closing is that final controlling element 90 ° of turning handle power are conducted to valve rod, then conducts to spool by valve rod, makes spool hold 90 ° of reciprocating rotations to realize switch.Valve is when closing, and final controlling element rotates clockwise, by valve rod band movable valve plug.During valve opening, final controlling element rotates counterclockwise, by valve rod band movable valve plug.During valve open work, due to spool special construction, spool outlet is facing to valve pocket sidewall, and formation vorticity in media flow to valve pocket, makes coal dust medium can not be deposited in phenomenon in valve pocket because of long-term work.
The utility model also can have other various embodiments; when not deviating from the utility model spirit and essence thereof; those of ordinary skill in the art are when making various corresponding change and distortion according to the utility model, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the utility model.
These are only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
