The advantage: upper assembling type structure easy dismounting, as long as it can all take out the case structure to dismantle the valve gap bolt, the valve body may not descend the pipeline just can keep in repair, on -line maintenance is very convenient.
Description
Technical field
The utility model relates to a kind of dismounting and easy to maintenance, and helix structure action is more smooth and easy lighter, the low torque ball valve of upper dress formula of longer service life.
Background technique
Ball valve is a kind of valve rotated by valve rod drive spherical valve core and around the axis of valve rod.Be mainly used in blocking or connect the medium in pipeline, be widely used in every profession and trade.
Ball valve on existing market mainly contains floating ball ball valve, fixing spherical ball valve, V-arrangement ball valve, and swinging ball valve, also has double panel-type ball valve etc.Floating ball ball valve and fixing spherical ball valve open and close torque are very large, and adapted final controlling element cost is very high, and working life is low.V-arrangement ball valve and swinging ball valve are all one direction shut-off structures, and when double panel-type ball valve opens and closes, spool entirety moves up and down complex structure and is not suitable for for impurity medium.
Summary of the invention
Purpose of design: avoid the deficiency in background technique, designs a kind of dismounting and easy to maintenance, and helix structure action is more smooth and easy lighter, the low torque ball valve of upper dress formula of longer service life.
Design proposal: in order to realize above-mentioned purpose of design, the utility model is in design: the low torque ball valve of dress formula in one, comprise the valve body, valve gap and the spool that are provided with valve seat, the valve body being provided with valve seat installs valve gap, cavity is formed between valve gap and valve body, spool is established, valve gap upper end connection bracket in cavity.
Further, valve gap is built with band spiral chute sliding sleeve.
Further, valve gap central authorities are provided with cylindrical cavity, and cylindrical cavity is built with band spiral chute sliding sleeve, and described support covers on band spiral chute sliding sleeve, and spool is against below band spiral chute sliding sleeve, establishes the roller be mated in the spiral chute of band spiral chute sliding sleeve.
Further, valve rod is through band spiral chute sliding sleeve, valve gap and support, and the valve rod upper end trapezoidal thread through support screws in nut, is connected with final controlling element.
Further, valve gap adopts Flange joint in bolt and valve body.
Further, spool comprises valve rod, conversion block and the spheroid be made up of two hemisphere, spool is arranged in valve body, the spheroid be made up of two hemisphere is formed the through hole that a level is through, valve body have hold spheroid rotate with airtight/open the inner chamber of two ends valve seats outlet, valve rod lower end is fixedly connected with conversion block, two hemisphere upper ends have the first flange supplying the circle of conversion block insertion to lack through hole and raise up around, first flange of two hemisphere is respectively provided with a upper pin, conversion block has two interior skewed slots, on two hemisphere, two upper pins to penetrate in two in skewed slot respectively, conversion block is connected with spheroid upper end, along being provided with both sides second flange under hemisphere, second flange is provided with two lower bearing pins, body base is provided with fork-shaped running shaft, fork-shaped running shaft upper end is a flat body and is provided with two bottom arcs to become two grooves to upper end open, fork-shaped running shaft lower end is circular shaft, fork-shaped running shaft lower end circular shaft is inserted in valve body center hole, under two hemisphere edge the second flange on two lower bearing pins insert fork-shaped running shaft upper recess respectively.
Further, outlet port, described body cavity two ends studs with two valve seats.
Further, conversion block both sides are the scarce flat body of circle, two cover roller and roller shafts are equipped with in arc surface direction, both sides, top, roller is connected on roller shaft, both sides arc surface Spielpassung is in band spiral chute sliding sleeve endoporus, and the roller be located on the arc surface of both sides inserts in the spiral chute of band spiral chute sliding sleeve respectively.
Further, conversion block is provided with two interior skewed slots, and two interior skewed slots corresponding two hemisphere respectively, two upper pins are separately fixed on corresponding hemisphere through interior skewed slot.
The present invention is compared with background technique, and one is upper dress formula structure easy accessibility, as long as valve core structure part can all take out by dismounting valve gap bolt, valve body can not just can keep in repair by underground pipelines, and on-line maintenance is very convenient; Two is that built-in spiral chute is avoided by the dust impurity in environment and corrosive gas matter corrodes, the roller system coefficient of rolling friction coordinated with it reduces, make helix structure action more smooth and easy lighter, longer service life, moreover external structure changes, valve total height reduces, and total height is than identical bore gate valve, and swing type orbit ball valve all reduces; Three be open and close without wearing and tearing: during valve opening, rotate again after ball seal face is separated with sealing surface of seat, go to 90 bottom valve standard-sized sheets, when closing valve, by first spinning ball 90 degree, after putting in place, just make ball seal face and sealing surface of seat closed; Four is low torque operation: because spheroid during open and close and valve seat are without to rub therefore valve rod rotates or axial motion is all very light, can the final controlling element of selection of small moment of torsion, reduces deployment cost; Five is double-valve-seat designs: double-valve-seat double-sealing face adapts to bidirectional fluid medium, ensure that two way sealed is not leaked, improves the using scope of product; Six is self-cleanings: after ball seal face is departed from, and the medium of flowing can flow along sealing surface, is rinsed well by the impurity on sealing surface; Seven is optimal flow characteristic: all-pass is through standard, and crushing stream damages few, improves pipeline system efficiency; Eight is long lifetives: during opening/shutting valve, sealing surface is without friction, reduces the working life that moment of torsion adds various final controlling element; Decrease the wearing and tearing of sealing surface, increase the working life of valve.
