This first leakage preventing mechanism 6 and second leakage preventing mechanism, 7 structures are to be left and right sides mirror image symmetry shape; And it is airtight in opposite directions about being by being butted on valve ball 4 outer circumferential face left and right sides; And by being butted on 32 of this seat body 31 and side covers, and can prevent that liquid from leaking in the ball-and-socket 310 from perforation 40, and this valve ball 4 mechanism 5 that can be open and close is driven; And be communicated in the conduction position of 320 of through holes at one with its perforation 40, and one changes between the closed position of 320 of through holes with its outer circumferential face sealing block resistance.Be convenient explanation, below only describe with regard to the detailed structure of first leakage preventing mechanism 6.
This first leakage preventing mechanism 6 comprises that airtight the leaning on toward right limit by the ring-type that is butted on these valve ball 4 outer circumferential faces and is communicated with ball-and-socket 310 first ball seat 61, one of turning right is butted on this first ball seat 61 and radially leans on the ring-type first leakproof pad 62 that is butted on seat body 31 inner edges, one to lean on ring-type first back of the body ring 63 that is butted on this first leakproof pad 62 toward right limit outward, and an elastic top be butted on the left of side cover 32 and this first carry on the back ring-type first disk spring 64 that encircles between 63 left surfaces.
It all is to be processed by the metallic material that can bear high temperature that this first ball seat 61, the first leakproof pad 62, first are carried on the back ring 63 and first disk spring 64, be difficult for producing thermal distortion, but employed metallic material does not exceed with identical.
This first ball seat 61 has a ring-type first pedestal portion 611, and one from the first pedestal portion, 611 outer circumferential face left borders radially ring-type first retaining of projection outward lean on portion 612.The first leakproof pad 62 is to lean on toward right limit to be butted on first retaining and to lean on portion's 612 left surfaces, and has one and lean on toward right limit and to be butted on first back of the body ring 63, and pushes inclined-plane 621 by the ring-type first of directly yearning for the tilt extension from left to right gradually.
First back of the body ring 63 comprises the spacing ring-type first ring body portion 631 that is butted on these first pedestal portion, 611 outer circumferential faces, of leaning on from the turn left ring-type first spacing ring portion 633 of projection of the first ring body portion, 631 left surface outer rim one, reaches one from the turn right projection and rely on the ring-type first pushing tow ring portion 634 of this first leakproof pad 62 of the first ring body portion, 631 right flanks.This first pushing tow ring portion 634 have one by from left to right gradually the footpath yearn for tilt and extend, and corresponding rely on outward this first push inclined-plane 621 the first pushing tow inclined-plane 635.
The element structure of this second leakage preventing mechanism 7 is entirely identical to first leakage preventing mechanism 6, comprises a ring-type second ball seat 71, ring-type second leakproof pad 72, ring-type second back of the body ring 73, and ring-type second disk spring 74.And it all is to be processed by metallic material that this second ball seat 71, the second leakproof pad 72, second are carried on the back ring 73 and second disk spring 74.
When ball valve of the present invention uses; First disk spring 64 and second disk spring 74 be elasticity pushing tow first back of the body ring 63 and second back of the body ring 73, the first leakproof pad 62 and the second leakproof pad 72 in opposite directions; And first ball seat 61 and second ball seat 71; Make first ball seat 61 and second ball seat 71 airtight by being butted on valve ball 4 outer circumferential faces; And by about the quilt first of the pushing tow back of the body ring 63 and second back of the body ring 73 in opposite directions, and the first pushing tow inclined-plane 635 of first back of the body ring 63 encircles 73 the second pushing tow inclined-plane 735 with second quilt, radially first of the pushing tow first leakproof pad 62 pushes second of the inclined-plane 621 and the second leakproof pad 72 and pushes inclined-plane 721 outward in opposite directions; Force the first leakproof pad 62 and the second leakproof pad 72 airtight by being butted on ball-and-socket 310 inner edges, and reach the sealed against leakage function with its outer circumferential face.
When valve ball 4 is switched to conduction position, when making its perforation 40 be communicated in 320 of through holes, can make liquid from the right side side cover 32 turn left through, and flow into left side side cover 32.When this valve ball 4 was switched to this closed position, valve ball 4 was airtight by being butted on first ball seat 61 and second ball seat 71 with its outer circumferential face, and the sealing block resistance is in 320 of through holes, and then the conveying of stop liquid.
Like Fig. 4, shown in 5; When valve ball 4 is positioned at closed position; Or with the local block resistance of its outer circumferential face in 320 of through holes; And when being local on state, the high pressure-temperature fluid in the conveying can directly be turned left and impacted this valve ball 4 and be exposed to outer circumferential face position, through hole 320 place, pushes first ball seat 61 to and valve ball 4 turned left.At this moment, this first leakproof pad 62 and first back of the body ring 63 are to be in by this first ball seat 61 and this first dish-shaped shell fragment 64 state of supporting of elastic clip in opposite directions, compel to be butted on valve ball 4 outer circumferential faces so first ball seat 61 is still airtight.At this moment; Leaned on turn left the relatively first leakproof pad 52 of pushing tow of portion 612 by first retaining of first ball seat 61, also can be by the first pushing tow inclined-plane 635 of this first back of the body ring 63 pushing tow outward relatively radially, and still urgent by being butted on ball-and-socket 310 inner edges; So first leakage preventing mechanism 6 is except still possessing the drip-preventing function; Also can to valve ball 4 elastic buffer function be provided, and one prevents the turn right limit function of over-deflection of valve ball 4 simultaneously by the elastic force of this first belleville spring 64.
In this simultaneously, second disk spring 74 of second leakage preventing mechanism 7 elasticity pushing tow second back of the body ring 73, the second leakproof pad 72 and second ball seat 71 of also can turning left makes second ball seat 71 urgent in valve ball 4 outer circumferential faces, makes second leakage preventing mechanism 7 possess drip-preventing function equally.
In addition, by the cushion that 6 pairs of valve balls 4 of first leakage preventing mechanism provide, can make be open and close mechanism 5 of valve ball 4 drive and pivot; And the self closing position is switched in the process of conduction position; Valve ball 4 is unlikely to turn left excessively urgent by being butted on first ball seat 61, and is difficult to turned, and makes ball valve of the present invention arrange in pairs or groups an automatic equipment when driving this opening/closing mechanism 5; Can reduce automatic equipment to these opening/closing mechanism 5 required strength that apply, so can select the lower automatic equipment of power for use.
In addition, mandatory declaration be because this ball valve is when using; Main pressure bearing person is first leakage preventing mechanism 6 of forward side that is positioned at the liquid of conveying, so when implementing, second leakage preventing mechanism 7 is not necessity valve ball 4 is provided cushion; So the structural design of second leakage preventing mechanism 7 can not need adopt the design of first leakage preventing mechanism 6; As long as integrated member all must be the refractory metal material, and can turn left and compel to be butted on valve ball 4 outer circumferential faces and seat body 31 inner edges, and reach the function of airtight leakproof.
Take a broad view of above-mentioned; Leakage preventing mechanism 6,7 through metal material is airtight compels to be butted on the structural design of 4 of side cover 32 and valve balls, when the liquid that makes ball valve of the present invention be applied to HTHP is carried, is difficult for producing because of high temperature deformation liquid leakage or interior leakage phenomenon; And the cushion function that can be provided by first leakage preventing mechanism 6 of the forward side of the highly pressurised liquid that is positioned at conveying; Effectively avoid excessively urgent the leaning on of valve ball 4 to be butted on first ball seat 61, and the resistance can reduce valve ball 4 quilts and turn the time make valve ball 4 be easy to turned; And conveniently drive with the automation equipment of hanging down power, quite convenient and practical.
