For technical characteristics of the present invention, object and effect being had more clearly, understand, now contrast accompanying drawing explanation the specific embodiment of the present invention.
The invention provides a kind of valve assembly, although this double seated valve of sentencing " push-to-open " type is described disclosed specific embodiment, but disclosed valve assembly is also equally applicable to the valve of other types and structure, as " push-to-close " type double seated valve.The present invention is not limited to the valve of particular type, and disclosed valve arrangement is also applicable to many dissimilar media.
The valve seat that valve assembly provided by the present invention comprises a valve body as shown in Figure 1, be arranged on body cavity with one can relative described valve seat motion valve plug, moving up and down of the relative valve seat of valve plug can limit valve different open positions (standard-sized sheet, portion separately or claim half-open, close).
In such double seated valve, the first valve seat and the second valve seat longitudinally arrange, valve plug has one first contacting part and one second contacting part, the first contacting part can contact with the first valve seat and form sealing, the second contacting part has an annular projection, deformable after projection and described the second valve seat extruding, the second contacting part can be touched and be formed sealing by the projection after described distortion and described second valve seated connection.
When the first contacting part contacts with the first valve seat, form sealing, meanwhile, projection and second valve seated connection that the second contacting part passes through after distortion touch while forming sealing, just define the closed position of valve.
When the relative valve seat motion of valve plug, thereby the first contacting part and the first valve seat disengage, and meanwhile, after the projection after the second contacting part distortion also disengages with the second valve seat, just define valve by the different conditions partially opening to standard-sized sheet.
Meanwhile, valve body also has one for preventing the blocked part of valve plug rotation on chamber within it, thereby realizes better sealing effect.
As shown in Fig. 2 A, 2B and Fig. 3, valve body 1 has the first valve seat 11 and the second valve seat 12 longitudinally arranging.
In partial enlarged drawing as shown in Figure 2 A and 2B, the first valve seat 11 has first inclined-plane 111, also there is a restriction face 17, the first inclined-plane 111 can contact with valve plug (not shown), when contact, form a sealing, and restriction face 17 can define an opening with together with the restriction face (not shown) of offside, this opening and valve plug (not shown) can together with limit the different flow of medium.
In the partial enlarged drawing of the second valve seat 12 as shown in Figure 3, the second valve seat 12 also has second inclined-plane 122 and holds face 123, the second inclined-plane 122 can contact with valve plug (not shown), when contact, form a sealing, and hold face 123 can with together with the plane (not shown) of offside, define an opening and hold valve plug, valve plug and this hold the mode with Spielpassung between face 123 and are placed in valve body 1.
In valve plug 2 as shown in Fig. 4 A and 4B, valve plug 2 has two lugs that are oppositely arranged 29 in its bottom one side, lug 29 is outwards outstanding along direction perpendicular to axial direction, and extend along the direction with parallel to an axis, between two lugs 29, form a draw-in groove 290, at the top of valve plug 2, offer 2 openings 28, in the time of in being placed on valve body (not shown), medium can flow into valve plug 2 inside from opening 28.
In the partial enlarged drawing of valve plug 2 as shown in Figure 5, valve plug 2 has a distal face 24 and a fitting surface 23, it between distal face 24 and fitting surface 23, is the second contacting part 22 of valve plug 2, the second position of contacting part 22 in valve body can be designed to contact with the second valve seat 12, to form lower seal.
The second contacting part 22 can be particularly second surface of contact 222 with annular projection 20, in order to realize projection 20 and the deformable object of the second valve seat 12 extruding, projection 20 can be chosen as to hardness lower than the material of valve seat 12 hardness, such as valve seat 12 is cast iron, and projection 20 is bronze material, because bronze hardness is lower than cast iron, when valve plug 2 is applied to certain pressure, while making the projection 20 of bronze material and the valve seat of cast iron materials 12 that extruding occur, can there is trickle plastic deformation in the projection 20 of bronze material, projection after distortion just can form a surface of contact adapting with compressive plane, 12 of surface of contact and the second valve seats just can form reasonable sealing effect.
This projection 20 can be a right angle boss, and this right angle boss has a horizontal plane 203 and a vertical surface 202, and when applying certain pressure, the square edge that horizontal plane 203 and vertical surface are 202 can push with valve seat 12, is easier to distortion.
In another partial enlarged drawing of valve plug 2 as shown in Figure 6, valve plug 2 has first contacting part 21 that connects fitting surface 23 and restriction face 27.The first contacting part 21 can be particularly first surface of contact 211, the first position of contacting part 21 in valve body can be designed to contact with the first valve seat 11, especially, by the first surface of contact 211, with the form firmly contacting, form top seal with the first valve seat 11, for this reason, the first surface of contact 211 can be substantially parallel with the first inclined-plane of the first valve seat 11, after two substantially parallel face contacts, form a sealing surface, thereby guarantee when closed position, the dielectric leakage flow control of this first surface of contact 211 is in desired scope.
Fig. 7 A and 7B draw on valve plug, the schematic diagram while making valve body in the closed position.In the figure, valve rod 3 stretches into body cavity 16 by the upper opening 14 of valve body 1, and one end connects valve plug 2, and the other end connects final controlling element (not shown) by bindiny mechanism 4.
When final controlling element upwards pulls valve plug 2 when static by bindiny mechanism 4 band ovable valve stems 3, valve is in closed condition (as shown in Fig. 7 A and 7B), when final controlling element pushes valve plug 2 downwards by bindiny mechanism's 4 band ovable valve stems 3, valve is in opening state (as shown in figure 11).
By means of Fig. 8 A, 8B, 9A, 9B, illustrate that valve is when the closed condition now, the relative position of valve plug 2 and valve body 1.
As shown in Fig. 8 A and 9A, when valve is during in closed condition, the medium circulation limiting between face 17 and valve plug restriction face 27 at valve body is blocked, and the medium flowing down from valve plug opening 28 is also because the second contacting part 22 contacts with the sealing of the second valve seat 12, thereby the circulation of blocking-up medium, realizes closing of valve.
As shown in Figure 8 B, owing to existing between the first contacting part 21 of valve plug 2 and valve body the first valve seat 11, firmly contact sealing, particularly, because valve plug the first contacting part 21 has first surface of contact 211 substantially parallel with the first inclined-plane 111 of the first valve seat 11, the hard contact of two faces just forms a sealing surface, and the effect of sealing is that the medium leakage flow limiting between face 17 and valve plug restriction face 27 at valve body is controlled in desired scope.
As shown in Figure 9 B, boss on valve plug the second surface of contact 222 is because material hardness is lower, be easy to extrusion, so form afterwards a boss 20 ' after distortion in extruding, this boss 20 ', due to the second inclined-plane 122 extruding with the second valve seat 12, is close to the boss surface of contact 200 parallel with the second inclined-plane 122 so formed one.By means of this boss surface of contact 200, can realize the sealing of valve plug 2 and the second valve seat 12 just, make medium reveal flow and be controlled in desired scope.
Because needing relative valve seat (11,12), valve plug 2 moves up and down, so can adopt Spielpassung at valve plug fitting surface 23 and the second valve seat between the one side (holding face 123) near valve plug.No matter valve plug need to move upward or move downward, all can be more for convenience.
And rotate in valve body 1 inside for fear of valve plug 2, affect sealing effect, valve plug 2 has at least one pair of lug being oppositely arranged 29, between lug 29, form a draw-in groove 290, as shown in Figure 10 A and Figure 10 B, valve body 1 has a 19， blocked part, blocked part 19 adapting with draw-in groove 290 positions and can stretch at least partly in draw-in groove 290, prevent that valve plug 2 from rotating in the interior appearance of valve body 1, thereby have influence on sealing effect.
Blocked part 19 can be set to the various forms such as projection, boss, in addition, in order to realize, avoid valve plug 2 in valve body 1 inner rotation, can also carry out other designs, such as blocked part 19 is designed to a groove, valve plug 2 arranges the protuberance that can embed this groove in relevant position, the cooperation of dependence groove and protuberance realizes avoids effect in relative rotation.
As Figure 11 shows the schematic diagram of valve when the half-open position, with reference to the partial enlarged drawing shown in figure 12A and Figure 12 B, when the relative valve seat (11 of valve plug 2, 12) while moving downward, owing to disengaging between the first contacting part 21 of valve plug 2 and valve body the first valve seat 11, particularly, because the first inclined-plane 111 of the first surface of contact 211 on valve plug the first contacting part 21 and the first valve seat 11 disengages, the sealing surface originally forming by hard contact between two faces has not just existed yet, the medium limiting between face 17 and valve plug restriction face 27 at valve body can be taken advantage of a situation and flow down, media implementation connects.And distortion after boss 20 ' also can disengage with the second inclined-plane 122 of the second valve seat 12, valve plug 2 moves downward along fitting surface 23.
Describe how the valve plug in the embodiment of the present invention is fit into the process in valve body now.
Valve plug is stretched in valve body 1 inner chamber 16 by valve body 1 lower openings 18 shown in Fig. 1, the blocked part 19 of valve body can be stretched in the draw-in groove of valve plug lug formation.
The projection concrete construction of valve plug is that, when valve plug is stretched in valve body, in the situation that not applying external force, when projection contacts with the second inclined-plane, the first inclined-plane and the first surface of contact exist certain interval.At this moment, by applying certain external force, projection just can be pushed with the second inclined-plane, because the material hardness of projection is less than the second inclined-plane, so projection can deform, produce a boss surface of contact that can adapt with the second inclined-plane, and then form sealing surface between boss surface of contact and the second inclined-plane, and correspondingly, the gap between the first inclined-plane and the first surface of contact also can be decreased to minimum level significantly, until realize a kind of sealing effect of good hard contact between the two.So far, just valve plug is mounted in valve body.
Be understandable that, as shown in figure 13, the externally applied forces KN of institute should increase along with the diameter of valve plug and strengthen, that is to say, if the aperture DN of valve body is large, valve plug diameter also can correspondingly strengthen, to valve plug externally applied forces, KN also should strengthen, so that the annular projection on valve plug produces distortion.
Owing to being just provided with annular projection on valve plug, and use the mode of extruding to form the sealing effect of valve plug and valve seat, so without valve plug is carried out to accurate machining, so that it possesses the contact shape adapting with valve seat.Meanwhile, also without valve seat being carried out to the operations such as grinding, only need push valve plug just can realize sealing effect good between valve plug and valve body, has saved processing cost.
Be to be understood that, although this specification is described according to each embodiment, but not each embodiment only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, technological scheme in each embodiment also can, through appropriately combined, form other mode of executions that it will be appreciated by those skilled in the art that.
The foregoing is only the schematic embodiment of the present invention, not in order to limit scope of the present invention.Any those skilled in the art, not departing from equivalent variations, modification and the combination of doing under the prerequisite of design of the present invention and principle, all should belong to the scope of protection of the invention.
