Description
Technical field
The utility model relates to a kind of valve valve that has smooth seal face, specifically a kind of Totally-enclosed large differential pressure open-close glasses valve that separates or compress by valve body moving handle sealing surface of seat.
Background technique
In the big-and-middle-sized gas pipeline of iron and steel and metallurgical class enterprise, all be to adopt the two-stage valve to turn-off ducted coal gas medium at present.The prime valve generally is to use the dish valve, and back step valve gate open often is to use glasses valve.The dish valve of prime can be with to press and open and close, but its poor sealing performance; The glasses valve of back level can not be with to press and open and close, but its good seal performance.So, normal use for gas pipeline, prevent gas leakage, have to adopt the two-stage valve: the pressure difference after reducing with prime dish valve in the gas pipe line of level glasses valve front end and back end, realize the shutoff fully and the sealing of gas pipeline with back level glasses valve.The repeating of this two-stage valve is provided with, and not only improved the buying and the user cost of valve, strengthened the area and the cost of valve operation platform, but also increased the valve integrated operation time of big-and-middle-sized gas pipeline break-make, reduced work efficiency.
The model utility content
The purpose of this utility model just provides a kind of prime shut-off valve that need not be provided with just can safely, successfully implement the Totally-enclosed large differential pressure open-close glasses valve that band is pressed the keying operation.
The utility model is achieved in that the structure based on totally-enclosed horizontal lens valve, be connected to the moving valve of deciding valve body and band bellows in the front end and back end of main valve case, be connected to secondary clack box in the both sides of main valve case, the valve plate that has through hole circle and blind hole circle is being decided between valve body and the moving valve, valve plate is suspended on the guide rail that is fixed in the main valve box top by some hanging wheels of its top cross-under, on main valve case and moving valve, valve plate is installed and compresses tripping-gear, end face at main valve case and valve plate is equipped with valve plate transposition transverse-moving mechanism, and institute's improvements are to have set up valve plate pressure-bearing translation mechanism on the main valve case.
Utilize this valve plate pressure-bearing translation mechanism, just can cooperate valve plate on the glasses valve to compress the control procedure of tripping-gear, valve plate is implemented along the driven in translation of active, the big distance of its plate face vertical line direction.Utilize the effect of this pressure-bearing translation mechanism, just can overcome the immense pressure that the coal gas medium comes source in the pipeline, make valve plate plate face vertical line direction along valve plate in the valve seat space of two valve bodies carry out translation, thereby make blind hole circle or the valve seat on through hole circle and the valve body on the valve plate realize breaking away from smoothly.Because being suspended on the valve plate of deciding between valve body and the moving valve also will carry out horizontal transposition and move between two secondary clack boxes of main valve case and its both sides, therefore, should utilize valve plate pressure-bearing translation mechanism to the big pressure reduction driven in translation of valve plate enforcement along the plate face vertical line direction of valve plate, also mobile otherwise influence the normal laterally transposition of valve plate.
For this reason, a kind of implementation of valve plate pressure-bearing translation mechanism is: based on the existing pushing-pulling-plate that is fixedly welded on the moving valve, upper and lower edge at pushing-pulling-plate is connected to the transverse slat that stretches to the valve plate direction respectively, is connected to some vertical shafts on two transverse slats respectively, socket roller on the vertical shaft; Be connected to gusset and following gusset on the upper and lower frame of valve plate respectively, the transverse slat face of upper and lower gusset strides across roller, and the riser face of upper and lower gusset is between pushing-pulling-plate and roller.
This valve plate pressure-bearing translation mechanism is to have designed a valve plate to force pulling mechanism between moving valve and valve plate, this mechanism compresses tripping-gear by valve plate and utilizes the pull back power of moving valve of pushing-pulling-plate, in the process that the moving valve front end is pulled back, utilization is connected on the pushing-pulling-plate, on on the pair of rollers valve plate on the lower cross plate, the effect of the riser face of following gusset and whole pulling valve plate, make it to be overcome the pressure that coal gas medium in the pipeline comes source, side to moving valve produces integral translation, thereby blind hole circle or through hole circle on the valve plate are broken away from smoothly with the valve seat of deciding on the valve body.Though in the process of pulling valve plate, roller in the valve plate pressure-bearing translation mechanism is bearing the immense pressure of coal gas medium to valve plate all the time, but because the two is to realize being in contact with one another along inner plane by the wheel face and the upright of upper and lower gusset of roller, this is a kind of rolling contact, therefore, this contact horizontal transposition that can not influence valve plate is moved.When valve plate laterally replaces mobile end, valve plate when compressing tripping-gear and compressing operation, valve seat on the moving valve can promote valve plate to deciding valve body one side translation return, and through hole circle or the blind hole circle after the transposition is pressed between the valve seat of two valve bodies on the valve plate thereby make.
Second kind of implementation of valve plate pressure-bearing translation mechanism is: deciding socket one movable deckle board on the valve body, be connected to the transverse slat that stretches to the valve plate direction respectively on the upper and lower limit of movable deckle board, be connected to some vertical shafts respectively on two transverse slats, socket roller on the vertical shaft; Be connected to gusset and following gusset on the upper and lower frame of valve plate respectively, the transverse slat face of upper and lower gusset strides across roller, and the riser face of upper and lower gusset is between movable deckle board and roller; Four jiaos at movable deckle board are connected to pull bar respectively, and the outer end of pull bar joins with the linkage driving mechanism that is fixed on the main valve case.
This valve plate pressure-bearing translation mechanism is to have designed valve plate to force push-pull mechanism in the main valve case, and this mechanism need be equipped with one and overlap independently that linkage driving mechanism drives on the main valve case.Compress after tripping-gear pulls back the valve seat of moving valve and unclamp valve plate at valve plate, utilize this linkage driving mechanism that movable deckle board is applied active force, can according to MEDIA FLOW to, make the roller on the upper and lower transverse slat that is connected on movable deckle board, head on the upper and lower frame of valve plate and push away valve plate directly, or hook upper and lower gusset and the valve plate of pulling back.Like this, just can make valve plate overcome the immense pressure that the coal gas medium comes source in the pipeline, in the slit, valve seat space of two valve bodies, produce whole translation, thereby blind hole circle on the valve plate or the valve seat on a through hole circle and the side valve body are broken away from smoothly.Although promoting or spurring in the process of valve plate, roller on the movable deckle board is bearing the pressure of coal gas medium to valve plate all the time, but because the two is to realize being in contact with one another along inner plane by the wheel face of roller and the upper and lower frame or the upright of upper and lower gusset of valve plate, this is a kind of rolling contact equally, equally also can not influence valve plate and carry out horizontal the moving that evolution is done.Compress before tripping-gear compresses operation at laterally replace mobile end, valve plate of valve plate, control linkage driving mechanism, reverse direction actuation activity deckle board can make the valve plate integral inverted to the translation return.Afterwards, control valve plate again and compress tripping-gear, through hole circle or blind hole circle after replacing on the valve plate are pressed between the valve seat of two valve bodies.
Use this Totally-enclosed large differential pressure open-close glasses valve, in gas pipeline, keeping under the situation of normal medium working pressure, need not be poor by the pressure medium that the prime shut-off valve reduces before and after the glasses valve valve plate, utilize valve plate pressure-bearing translation mechanism just can realize the smooth disengaging or stable applying of valve plate, and the valve plate integral translation of big distance, and under the valve plate artesian condition, still the horizontal transposition that can successfully realize valve plate is moved, and has realized the smooth keying of glasses valve under big differential pressure conditions thus.And the full-closed structure of major and minor clack box has also been avoided the gas leakage in the valve opening and closing process.Like this,, just can realize that has realized installing single glasses valve thus on large-scale gas pipeline may to the blocking-up fully of the coal gas medium in the large-scale gas pipeline and open-minded by single glasses valve is set.Adopt this structure, on large-scale gas pipeline, just a glasses valve can only be set, and the prime shut-off valve need not be installed again or take other step-down measure, can reduce the construction area that quantity and valve operation platform are set of valve thus, valve purchase cost and operating platform cost have correspondingly also just been reduced, and single valve setting on the gas pipeline, also must shorten the integral valve door operation time of opening or turn-offing gas pipeline, improve work efficiency, improved the utilization efficiency and the benefit of glasses valve.
Because the full-closed structure of this novel glasses valve, making in the unlatching of glasses valve or closing does not have again the excessive situation of coal gas medium to take place in the closed procedure, improved the safety reliability of valve operation thus, ensure execute-in-place workman's personal safety, realized safety, the reliable operation of glasses valve.Simultaneously, owing to there is not coal gas excessive, also help environmental protection.

Among Fig. 2, in guide rail 13, guide rail 13 is fixed in the top of main valve case 3 at hanging wheel 14 supports of cross-under on the valve plate 11, and the two ends of guide rail are overhanging, penetrates the top in the secondary clack box 1.Valve plate in the utility model glasses valve compresses tripping-gear and is made up of linkage driving mechanism 2, pull bar 19 and pushing-pulling-plate 7.Linkage driving mechanism 2 is fixed on an end of main valve case 3, and join with it four or eight pull bars 19 penetrate main valve case 3 respectively, is connected on the corner of pushing-pulling-plate 7, and pushing-pulling-plate 7 is welded on the moving valve 5 between bellows and the valve seat.
Valve plate transposition transverse-moving mechanism in this novel glasses valve includes deceleration mechanism 12, sprocket wheel and plane rigid link chain 27.Deceleration mechanism 12 is fixed on the top (Fig. 1) of main valve case 3, and sprocket wheel is connected on the output shaft of deceleration mechanism 12, and is meshed with the planar rigidity chain 27 of valve plate end face.Under the drive of deceleration mechanism 12, sprocket wheel is stirred planar rigidity chain 27, and it is mobile that valve plate 11 is laterally replaced between main valve case 3 and secondary clack box 1.
As shown in Figure 2, valve plate pressure-bearing translation mechanism in this novel glasses valve is to be welded with the transverse slat 8 that stretches to the valve plate direction on upper edge that is welded in the pushing-pulling-plate 7 on the moving valve 5 and lower edge respectively, on transverse slat 8, be connected to some vertical shafts that are in line and arrange, on vertical shaft, be socketed with roller 9,17; Be welded with gusset 10 on the upper frame of valve plate 11, the transverse slat face of last gusset 10 strides across roller 9, and the lower edge of its riser face is between pushing-pulling-plate 7 and roller 9.Be welded with gusset 16 down on the lower frame of valve plate 11, the transverse slat face of following gusset 16 strides across roller 17, and the lower edge of its riser face is between pushing-pulling-plate 7 and roller 17.Also the retraction assembly of being made up of transverse slat, vertical shaft and roller directly can be fixed on the valve body of the moving valve 5 between bellows and the valve seat.This is a kind of valve plate pressure-bearing translation mechanism of pulling type.
When valve plate 11 is compressed by the sealing surface of seat of two valve bodies, the roller external diameter that is positioned at pushing-pulling-plate 7 upper and lower end should maintain a certain distance with the facade edge of upper and lower gusset, and the valve seat 5a that this distance should be a moving valve 5 compresses valve plate and be totally released half of institute's displacement distance fully.Like this, compress tripping-gear action at valve plate, with valve plate from be pressed to the process of unclamping, the valve seat 5a of moving valve 5 is pulled back by pushing-pulling-plate 7 earlier, the half of waiting to pull back, and the upper and lower two row's rollers on the pushing-pulling-plate 7 promptly contact and are adjacent to along inner face with the upright of the upper and lower gusset of valve plate.In the process that valve seat 5a is continued to pull back, the upper and lower two row's rollers on the pushing-pulling-plate 7 make it along with the valve seat 5a of moving valve is whole in the lump to left just by upper and lower gusset pulling valve plate 11.Continue it, valve plate can be separated with the valve seat 15a that decides on the valve body 15.Can make thus to keep the spacing that equates substantially between the valve seat on valve plate and two valve bodies, laterally replace at valve plate and just can not touch mutually when mobile or rub mutually with the valve seat on both sides.At this moment, the coal gas medium in the pipeline of valve both sides connects by the inner chamber of main valve case 3, and the pressure medium difference before and after the valve plate declines to a great extent thereupon, after this can carry out the horizontal ex-situ operations of valve plate.Carry out in the laterally transposition process at valve plate, upper and lower two row's rollers 9,17 on the pushing-pulling-plate 7 are straining at valve plate 11 all the time, overcoming the left pushing force of coal gas medium, and because the two is the contact matching of wheel and face, therefore the horizontal transposition that makes valve plate 11 be able to smoothly, stably carry out in the major and minor clack box is moved.After transposition finishes, valve plate compresses the tripping-gear reverse operation, the valve seat 5a of moving valve is moved to right, valve plate 11 can be in company with moving to right (when valve base chamber is the blind hole circle) under the pressure of coal gas medium, perhaps the valve seat 5a of passive valve body promotes to move to right (when valve base chamber is the through hole circle), till being compressed once more by the valve seat of two valve bodies.
Make valve plate 11 in company with in the process that moves to right at the above-mentioned pressure compression blind hole circle that passes through the coal gas medium, upper and lower two row's rollers 9,17 on the pushing-pulling-plate 7 are straining at valve plate 11 all the time, valve plate blind hole circle is fitted on the valve seat of deciding valve body reposefully, has prevented the generation of " pneumatic hammer " phenomenon and the pipe vibration that causes thus.
For making the valve plate walking that can laterally replace reposefully, on the basis of said structure, this novel glasses valve also is connected to the spacing guide mechanism 18 of front end tape guide wheel on main valve case 3.This guide mechanism is to connect vertical shaft between two flat boards, and cross-under upper saw pulley on the axle, upper saw pulley point to the riser face of gusset 10 and following gusset 16 respectively.So just can be in valve plate 11 laterally replaces mobile process, the upright spacing guide mechanism of a cover that increased along the outside at upper and lower gusset, under the synergy of this spacing guide mechanism, the horizontal transposition of valve plate 11 is moved will be smooth more, stable, reliable.This spacing guide mechanism also can play certain position limitation protection effect to the left-hand translation of valve plate, makes it avoid producing collision with the valve seat 5a of moving valve.
Use the glasses valve in the present embodiment, also can change MEDIA FLOW to, promptly the coal gas medium is to enter glasses valve from an end of deciding valve body 15.In this case, require the rigidity of spacing guide mechanism 18 to improve, quantity increases, and is that upper and lower two rows are provided with.When valve plate 11 is blind hole circles when being in the valve seat neutral position of two valve bodies, valve plate is to left if desired, and along with moving to left of the valve seat 5a of moving valve 5, valve plate 11 can move to left under the effect of pressure medium simultaneously.When valve seat 5a moves left to a half of total amount of movement, last gusset 10 on the valve plate and following gusset 16 just are close to spacing guide mechanism 18 respectively.At this moment, valve seat 5a continues to move to left, and it is motionless that valve plate then keeps.Realize the left of valve plate thus.Valve plate is when right translation if desired, and valve seat 5a moves right earlier, after treating to fit with the blind hole circle, promotes valve plate 11 and is overcoming the pressure that medium comes source and continue to move to right, till valve plate is compressed.Realize the right translation of valve plate thus.
Embodiment 2:
As shown in Figure 3, the basic structure of present embodiment and embodiment's 1 is identical, and just valve plate pressure-bearing translation mechanism is different.Valve plate pressure-bearing translation mechanism in the present embodiment is to decide socket one movable deckle board 23 on the valve body 15, be connected to the transverse slat 8 that stretches to the valve plate direction respectively on the upper and lower limit of movable deckle board, be connected to some vertical shafts respectively on two transverse slats, and the socket roller 9,17 on the vertical shaft; Be connected to gusset 10 and following gusset 16 on the upper and lower frame of valve plate 11 respectively, the transverse slat face of upper and lower gusset strides across roller 9,17; The riser face of last gusset 10 is between movable deckle board 23 and roller 9, and the riser face of following gusset 16 is between movable deckle board 23 and roller 17; Four jiaos at movable deckle board 23 are connected to pull bar 24 respectively, and the other end of pull bar joins with the linkage driving mechanism 20 that is fixed on the main valve case 3.The electronic linkage driving mechanism that this linkage driving mechanism can adopt existing valve plate to compress to use on the tripping-gear also can adopt by the linkage driving structural type by the sprocket wheel chain transmission such as cylinder, oil hydraulic cylinder, Electrohydraulic push rod, electric pushrod.This is a kind of valve plate pressure-bearing translation mechanism of self-powered, push-and-pull convolution, and its advantage is the restriction that is suitable for bigbore glasses valve and does not have installation direction.
If this glasses valve be moving valve 5 with medium come to gas pipe line join, be that the piped gas medium is to flow to the right from the left side of Fig. 3, so, valve plate compress tripping-gear action, by pushing-pulling-plate 7 with the valve seat 5a of moving valve after valve plate draws back, valve plate forwards releasing orientation to from impaction state.Control linkage driving mechanism 20 this moment, four pull bars 24 (latus rectum according to glasses valve can be established more) the promotion activity deckle board 23 that joins is with it moved to left, upper and lower two row's rollers 9,17 on the movable deckle board promptly promote valve plate 11, and the pressure that overcomes the piped gas medium is to left.Its translation distance should be the valve seat 5a of moving valve by impaction state half to releasing orientation institute displacement distance.Stability when moving for strengthening movable deckle board can be provided with some support rollers below movable deckle board 23.Through hole circle on valve plate 11 or blind hole circle are pushed away after the valve seat 15a that decides valve body 15, can carry out the horizontal transposition of valve plate and move.In this process, upper and lower two row's rollers 9,17 on the movable deckle board head on valve plate 11 all the time, overcoming the left pushing force of coal gas medium, and be equally because therefore the contact matching of wheel and face makes valve plate 11 be able to smoothly, stably laterally replace in major and minor clack box mobile.So, the guide function of the valve plate pressure-bearing translation mechanism in present embodiment when also laterally transposition is mobile with valve plate.After valve plate replaces traversing end, controlling linkage driving mechanism 20 moves to right movable deckle board 23, at this moment, upper and lower two row's rollers, 9,17 pulling valve plates 11 are in company with moving to right (when valve base chamber is the through hole circle), or under the pressure of coal gas medium (when valve base chamber is the blind hole circle), valve plate 11 in company with move to right (be at this moment roller prop up head on valve plate together return to remove move to right), till the through hole circle on the valve plate or blind hole circle and the stable applying of the valve seat 15a that decide valve body.At last, start valve plate and compress tripping-gear, the valve seat of two valve bodies compresses valve plate 11 once more.
If this glasses valve be decide valve body 15 and medium come to gas pipe line join, be that the piped gas medium is to flow to the left from the right side of Fig. 3, so, valve plate compress tripping-gear action, by pushing-pulling-plate 7 with the valve seat 5a of moving valve after valve plate draws back, valve plate forwards releasing orientation to from impaction state.Control linkage driving mechanism 20 this moment, and movable deckle board 23 is moved to left.If be that through hole circle on the valve plate is relative with valve seat at this moment, the upper and lower two row's rollers 9,17 on the then movable deckle board 23 promptly promote the upper and lower frame of valve plate 11, and valve plate integral body is moved to left; If be that blind hole circle on the valve plate is relative with valve seat at this moment, then valve plate 11 is subjected to the immense pressure of piped gas medium and produces the tendency that moves to left, and the upper and lower gusset on the valve plate frame 10,16 hooks the upper and lower two row's rollers 9,17 on the movable deckle board 23 immediately.When movable deckle board 23 moves to left, as letting kite fly away, when overcoming the piped gas pressure medium that valve plate bears, make valve plate 11 integral translation left.Stop after the certain distance that moves to left, at this moment, the valve plate both sides are equidistant substantially with the sealing surface of seat maintenance of two valve bodies respectively.After this can carry out the valve plate move operation that laterally replaces.Replace after the traversing end, can oppositely control linkage driving mechanism 20, make movable deckle board 23 drive valve plate 11, the pressure that overcomes the piped gas medium moves to right, and valve seat 15a final and that decide on the valve body steadily fits.At last, start valve plate and compress the tripping-gear counteragent, the valve seat of two valve bodies compresses valve plate 11 once more.Finish the keying operation of glasses valve thus.
