[embodiment 1]
Expression embodiment's 1 the integrated panel and the linkage structure of fluid device in Fig. 1, Fig. 2.The linkage structure of this integrated panel and fluid device is the single current road type structures that a kind of integrated panel 1 of the fluid course 3,4 that is formed with a pair of pipe shape by inside and the valve (open and close valve, stop valve etc.) that carries across cyclic sealing gasket G on the upper surface 1a of this integrated panel 1 are 2 that constitute, share longitudinal axis P.That is, be used for adopting identical structure each other to row's a pair of linkage structure.
As shown in Figure 1 and Figure 2, the structure of integrated panel 1 is, the inside of the sheet material of making at fluororesin such as PFA or PTFE (perhaps bulk) 5 is formed with the supply side fluid course 3,4 by vertical runner 3a, the 4a of the trend up and down that is opened on panel upper surface 1a and horizontal crossing current road 3b, a pair of pipe shape that 4b constitutes.The part of giving current drainage body runner 3,4 openings in this integrated panel 1 is called first fluid gives row's oral area 1A, then give among row's oral area 1A at this first fluid, vertical runner 3a, the 4a of pipe shape form the runner with axis P respectively.In addition, give row's oral area 1A at first fluid, the external diameter one side part that is opened on each fluid course 3,4 of its upper-end surface is formed with the first hermetic terminal t21 and the second hermetic terminal t22 down down respectively, they form with axis P is the ring-type at center, and has outstanding upward inside and outside circular protrusion 21.
As shown in Figure 1 and Figure 2, valve (example of fluid device) 2 has fluororesin clack boxes 6 that make, that above-below direction view shape is rounded such as PFA or PTFE, the underpart of this clack box 6 forms second fluid and gives row's oral area 2A, and this second fluid has for row's oral area 2A: with from the outstanding downwards state of bottom surface 6a vertically the pipe shape of configuration supply side fluid course 7 with laterally separating and the discharge side liquid runner 8 of the pipe shape that the state of opening vertically disposes at this supply side fluid course 7 to the side.That is, give row's oral area 2A at this second fluid, the supply side fluid course 7,8 of pipe shape forms the runner with axis P respectively.Promptly, lower end at clack box 6, outstanding downwards formation of mounting flange 9 of a pair of fluororesin of being made by PFA or PTFE or other materials with pair of bolts penetration hole 9a forms each mounting flange 9 by the 9A of pipe portion with flange part (export-oriented flange) 9B and fluid course 7,8.The mounting flange 9 of supply side is formed on the last first hermetic terminal t11 with outstanding circular protrusion 11 downwards, and the mounting flange 9 of discharging side is formed on the last second hermetic terminal t12 with outstanding upward circular protrusion 11.
A pair of sealing gasket G is mutually the same, is that example illustrates its structure with the sealing gasket G of supply side.Sealing gasket G is made by fluororesin such as PFA or PTFE, it comprises: the corresponding fluid course of the fluid up and down of supply side being given row's oral area 1A, 2A---promptly vertical runner 3a and supply side fluid course 7 are interconnected and the tubular fluid path W1 that forms, and partly form in external diameter one side of fluid path W1, and respectively be formed on first and second fluid give on the end face of row's oral area 1A, 2A on the first hermetic terminal t11 circular protrusion 11 and on a pair of annular slot 51,51 up and down of circular protrusion 21 tablings of the second hermetic terminal t12.
Promptly, the section shape of sealing gasket G is, inner circle wall 54 and periphery wall 55 that it comprises a pair of up and down annular slot 51,51 and is used to form these annular slots 51,51, simultaneously, the degree of depth of annular slot 51,51 up and down and width are symmetrical up and down in the same manner, and internal and external peripheral wall 54,55 also is bilateral symmetry, be line symmetry (the proximal line symmetry gets final product) with respect to the vertical center Z of the axis P direction of giving row's oral area 1A, 2A along first and second fluid and with these two lines of horizontal center line X that are somebody's turn to do vertical center line Z quadrature, form the shape of approximate H shape.The upper and lower end parts of inner circle wall 54 forms taper inner peripheral surface 52a, the 52a of upper and lower end parts to tilt the closer to the broad more shape extroversion of front end that inner peripheral surface 54a is fluid path W1, simultaneously, the upper and lower end parts of periphery wall 55 also forms upper and lower end parts interior taper outer circumferential face 53a, the 53a to inclination of outer circumferential face 55a.
The first fluid of integrated panel 1 give second fluid of the circular protrusion 21 of the following first hermetic terminal t21 of row's oral area 1A and valve 2 give row's oral area 2A on the interior external diameter both sides of circular protrusion 11 among the first hermetic terminal t11, be formed with ring-type push projection (example of ring-type pressing part) 12,13,22,23, this ring- type push projection 12,13,22,23 stops the annular slot 51 that is used to form among the sealing gasket G and gives prominence to the chimeric generation dilatating and deformable of the internal and external peripheral wall end 52,53 of formation because of annular slot 51 and circular protrusion 52 along axis P direction.
Below at sealing gasket G and last first hermetic terminal t11 explanation and the relevant structure of above-mentioned ring-type push projection.Inside and outside ring- type push projection 12,13 is symmetrical, this ring- type push projection 12,13 forms the circular protrusion of the preceding narrow shape of taper outer circumferential face 12a that lateral circle surface with circular protrusion one side tilts and taper inner peripheral surface 13a so that the paddy portion 14,15 that is surrounded by this ring- type push projection 12,13 and circular protrusion 11 present in narrow shape (top is contraction-like).That is, the last first hermetic terminal t11 is circular protrusion 11 and the ring- type push projection 12,13 of inside and outside both sides formation and the general name of paddy portion 14,15.
The internal and external peripheral wall 54 of sealing gasket G, the structure of 55 upper end portion is, it comprises respectively and ring-type push projection 12, taper inner peripheral surface 52a that 13 taper outer circumferential face 12a contacts with taper inner peripheral surface 13a and taper outer circumferential face 53a, and comprise and freely to enter 14, the annular seal projection of 15 preceding narrow shape (example of perisporium end) 52,53, under jointing state (with reference to Fig. 1), internal and external peripheral wall 54,55 upper end portion---be annular seal projection 52,53 enter corresponding paddy portion 14,15, the taper inner peripheral surface 52a of the taper outer circumferential face 12a of the last first hermetic terminal t11 and sealing gasket G is crimped, and the taper outer circumferential face 53a of the taper inner peripheral surface 13a of the last first hermetic terminal t11 and sealing gasket G also is crimped.
Then, in the upper end portion of sealing gasket G, utilize annular slot 51 and inside and outside annular seal projection 52,53 thereof to form and go up sealed department g11, and similarly form the lower seal g12 of portion in the underpart.Last sealed department g11 and the last first hermetic terminal t11 are chimeric and form chimeric sealed department 10, and the g12 of lower seal portion is chimeric and form chimeric sealed department 10 with the second hermetic terminal t21 down.
Describe the embedded structure of chimeric sealed department 10 below in detail at the last sealed department g11 of last first hermetic terminal t11 and sealing gasket G.As Fig. 2, shown in Figure 3, inside and outside paddy portion 14,15 and inside and outside annular seal projection 52,53 are mutually symmetrical respectively, be set at the relation of α °＜β ° between diagonal angle β ° of angle α ° of inside and outside paddy portion 14,15 integral body and inside and outside annular seal projection 52,53 integral body, the α that preferably is set at °+(20～40 °)=β ° such relation.Utilize this structure can obtain following advantage, promptly, under the chimeric mutually jointing state (aftermentioned) of circular protrusion 11 on the last first hermetic terminal t11 and annular slot 51, upper inner ring shape push projection 12 and upper inner ring shape sealing projection 52 is rendered as the state (with reference to the dummy line of Fig. 3) that its taper outer circumferential face 12a and taper inner peripheral surface 52a partly are crimped in internal diameter one side, play the effect of the S2 of secondary seal portion, stop the fluid that passes fluid course W1 to infiltrate between these inside and outside taper side face 12a, 52a.
Promptly, holding means 1 (aftermentioned) moves etc. to be drawn for row's oral area 2A for the row oral area 1A and second fluid first fluid to lean on mutually across sealing gasket G, thereby make first fluid give the annular slot 51 of the other end of the annular slot 51 of an end of the circular protrusion 11 of row oral area 1A and sealing gasket G and circular protrusion 21 that second fluid is given row's oral area 2A and sealing gasket G chimeric respectively, form chimeric sealed department 10; And, the formed ring- type push projection 12,13,22,23 of interior outside diameter that first and second fluid is given the circular protrusion 11,21 on the end face of row's oral area 1A, 2A be used to form on the sealing gasket G annular slot 51 and to inside and outside annular seal projection 52,53 butts of the outstanding formation of axial direction, constitute a kind of jointing state that has formed the anti-locking apparatus Y of scalable distortion, to suppress or to stop the chimeric dilatating and deformable that take place of inside and outside annular seal projection 52,53 because of annular slot 51 and circular protrusion 11,21.
The anti-locking apparatus Y of scalable distortion comes down to be made of taper outer circumferential face 12a, 22a, taper inner peripheral surface 13a, the 23a of each ring- type push projection 12,13,22,23, the butt (crimping) of (outward) side face 52a, 53a and these taper outer circumferential faces and inner peripheral surface 12a, 22a, 13a, 23a in the taper by corresponding sealing gasket G can produce each annular seal projection 52,53 and attempt component to the distortion of the close direction of annular slot 51 1 sides.That is, interior annular seal projection 52 is subjected to the compressing to external diameter one side, and outer ring-like sealing projection 53 is subjected to the compressing to internal diameter one side, and therefore, annular slot 51 narrows down, and has promptly produced to make circular protrusion 11,21 to radially fastening effect.In this case, each annular seal projection 52,53 is strong more the closer to the component effect that front end one side is subjected to, and therefore, circular protrusion 11,21 is strong more the closer to the compressing that root one side (front end one side of annular seal projection 52,53) is subjected to.
Therefore, even fluid is crossed the S2 of secondary seal portion and is arrived the S1 of once sealing portion, these fluids also can be sealed at the inlet position of chimeric sealed department 10, and can not infiltrate chimeric sealed department 10 the depths, be the deep inside of telescoping groove 51, its advantage is, the inside of telescoping groove 51 is not easy the purity or the proterties of the fluid that passes through after residual influence the because of fluid or mixture, foreign matter etc.
In addition, be set at the relation of d1＞d2 between the width d1 of last circular protrusion 11 and the width d2 of last annular slot 51, be preferably set to d1 * such relation of (0.6～0.8)=d2.In addition, be set at the relation of h1＜h2 between the degree of depth h2 of the outstanding length h1 of last circular protrusion 11 and last annular slot 51.Utilize these structures, its advantage is, last circular protrusion 11 and last annular slot 51, specifically be that inside and outside two lateral circle surfaces of going up circular protrusion 11 are suppressed with the corresponding interior outside circumference that goes up annular slot 51 and connect, formed the S1 of once sealing portion of the sealability excellence of performance prevention fluid leakage, meanwhile, the taper outer circumferential face 12a of upper inner ring shape push projection 12 is bound to contact with the taper inner peripheral surface 52a of upper inner ring shape sealing projection 52, thereby has formed the above-mentioned secondary seal S2 of portion well.
About chimeric sealed department 10, as shown in Figure 3, for the S of once sealing portion 1 that makes internal diameter one side works effectively,, then preferably be set at and make R1＜R2 establishment if will be expressed as R1, R2 with respect to the radius of axis P separately with respect to circular protrusion 11 (21) and annular slot 51.In addition, except the relation of h1＞h3 shown in Figure 3, also can be the relation of h1=h3 or h1＜h3 along the relation of the outstanding length h1 of the height h3 of the axis P direction of ring-type push projection 12,22 (13,23) and circular protrusion 11 (21).
In addition, the front end of inboard ring-type push projection 12 and the front end of annular seal projection 52,53 form the cutting shape that is unlikely to constitute the needle point fillet, i.e. inclined cutting face 12b and cutting face 52b, 53b.Utilize these structures, even a little dilatating and deformable has taken place in fluid course W1 one side in the front end of upper inner ring shape push projection 12, because of its be originally the cutting after shape, so only can form the very big section of opening midway at fluid course W1 is leg-of-mutton depression, the fluid that is present in this recess is easy to spill out, and can not produce hydrops in fact.And, the angle of release of this depression, be that the angle of inclined cutting face 12b and taper inner peripheral surface 52a is enough big, also avoided the hydrops that produces because of surface tension.In addition, the chamfered edge shape 11a of portion through chamfered edge processing has been adopted in interior all bights of circular protrusion 11 front ends and periphery bight, and therefore, being pressed in the annular slot 51 of narrower in width moved and can successfully be carried out, and can not cut to pieces and pull.
In addition, shown in Figure 13 (a), make circular protrusion 11 form section after the chamfered edge formation 11a of portion in interior all bights of circular protrusion 11 front ends and periphery bight strengthened clearly, thereby form the structure that circular protrusion 11,21 enters annular slot 51 easily the closer to the thin more shape of front end.If adopt this structure, even with the suitable state of expecting a little having taken place for row's oral area 1A, 2A and the relative position of sealing gasket G when assembling, departs from first, second fluid, inside that taper is planar or the outside chamfered edge shape 11a of portion can play guiding function, and circular protrusion 11,21 is entered in the annular slot 51 effectively.Chimeric sealed department 10 in this case is with regard to becoming by the embedding part on the top of the root of circular protrusion 11,21 and annular slot 51 and the structure that forms.
In addition, shown in Figure 13 (b), also the chamfered edge shape 11a of portion further can be strengthened, make the inside and outside lateral circle surfaces of circular protrusion 11,21 become the tapered side side face 11a of whole inclinations, thereby form extreme the closer to the thin more shape and structure of front end.In this case, circular protrusion 11, the 21 easier annular slots 51 that enter, following advantage is also arranged simultaneously, promptly produced circular protrusion 11,21 with the wide wedge effect of annular slot 51 supports, the position, top of annular slot 51 is crimped on the line way of contact or with minimum area with the root of circular protrusion 11,21, can realize sealing function more effectively.
The global shape of the ring-type push projection 13 in the outside is different with inboard ring-type push projection 12, with the consecutive state of taper inner peripheral surface 13a of ring-type push projection 13 under, existence is used to form perimembranous 9b in the lower end of underpart of clack box 6.In addition, down the global shape of the first hermetic terminal t21 is also different with inboard ring-type push projection 22, with the consecutive state of taper inner peripheral surface 23a of ring-type push projection 23 under, existence is used to form perimembranous 5b in the upper end of upper end portion of sheet material 5. Perimembranous 5b, 9b performance guidance function when the g11 of upper-lower seal portion, g12 with sealing gasket G are embedded into up and down among the first hermetic terminal t11, the t21 in these upper and lower end also can be brought into play the function of the dilatating and deformable of the periphery wall 55 that stops sealing gasket G simultaneously with taper inner peripheral surface 13a, 23a.
In addition, shown in the dummy line of Fig. 6, if will on the periphery wall 55 of sealing gasket G, form as one by the dismounting flange 1f of laterally projecting ring-type, then its advantage is, when give row's oral area 1A, 2A from first or second fluid, extracting sealing gasket G, pull flange 1f with instrument or finger, just can remove at an easy rate.In this case, the thickness setting of dismounting flange 1f is to give the littler value in gap of arranging between oral area 1A, the 2A than first and second fluid under the jointing state.
Be described in further detail chimeric sealed department 10.As Fig. 2, shown in Figure 3, the angle of release of taper side face 12a, the 13a of ring-type push projection 12,13 (angle of release of paddy portion 14,15) D is set at the value (50 °≤D °≤70 °) in 50～70 degree, simultaneously, the wedge angle E of taper side face 52a, the 53a of annular seal projection (perisporium end) 52,53 is set at the value (60 °≤D °≤80 °) in 60～80 degree.In addition, angle of release D and wedge angle E are set at, and equal wedge angle E i.e. [D °+(10～20 °)=E °] after angle of release D adds.Better value is, angle of release D is set at 69～71 degree (D °=70 ± 1 °), and wedge angle E is set at 79～81 degree (E °=80 ± 1 °), and wedge angle E equals angle of release D+9～11 degree (E °-D °=10 ± 1 °).
In addition, the Cutting angle Ds of the inclined cutting face 12b of ring-type push projection 12 is set at 49～51 degree (Ds=50 ° ± 1 °), and the inclination angle Es of front end cutting face 52b, the 53b of perisporium end 52,53 is set at 124～126 degree (Es °=125 ° ± 1 °).By such angular setting, taper outer circumferential face 12a and taper inner peripheral surface 52a butt under the line contact condition of ring-type, the S2 of secondary seal portion performance sealing lip effect.In addition, between taper inner peripheral surface 13a and the taper outer circumferential face 53a also external diameter one side end at them produce seal action.In addition, though its diagram is omitted, under the situation that does not have perimembranous 9b in the lower end (under the symmetrical situation of section shape of the embedding part of sealing gasket G in integrated panel or the fluid device), also be formed with identical inclined cutting face in the ring-type push projection 13 in the outside, produce above-mentioned sealing lip effect with inclined cutting face 12b.
That is above-mentioned annular seal projection (perisporium end) 52,, 53 taper side face 52a, 53a (taper inner peripheral surface 52a, taper outer circumferential face 53a) draw the direction of leaning on mutually for row's oral area 2A for row oral area 1A and above-mentioned second fluid with respect to above-mentioned first fluid---promptly draw wedge angle E to be set at above-mentioned ring-type push projection 12 by direction, the taper side face 12a of circular protrusion 11 1 sides in 13,13a (taper outer circumferential face 12a, taper inner peripheral surface 13a) draw angle of release D to go up the value that increases by 10～20 degree and obtain with respect to above-mentioned by direction, preferably add about 10 degree or 10 degree and the value that obtains.In addition, above-mentioned wedge angle E is set at about 60～80 degree, preferred 80 degree or 80 degree.
Adopt this advantage that wedge angle E and angle of release D are set near the structure of the obtuse angle values of 90 degree to be, ring- type push projection 12,13 is drawing overhang by direction (axially) less than its radial width, intensity and rigidity have relatively been improved, both limit the expansion of annular seal projection 52,53, and can more effectively suppress himself (ring-type push projection 12,13) dilatating and deformable diametrically again.In addition, can reduce the taper side face 52a, the 53a that produce to the insertion of paddy portion 14,15 because of annular seal projection 52,53 with ring- type push projection 12,13 to the component that radially struts, this also can suppress ring- type push projection 12,13 dilatating and deformable diametrically.
The following describes holding means I.As Fig. 2, shown in Figure 3, the first fluid of integrated panel 1 draws for row's oral area 2A mutually for second fluid of row oral area 1A and valve 2 and leans on across sealing gasket G, meanwhile, utilize this to draw and make first fluid give the last sealed department g11 and second fluid of the last first hermetic terminal t11 of row oral area 1A and sealing gasket G chimeric respectively, form each chimeric sealed department 10 to the g12 of lower seal portion of following first hermetic terminal t21 that arranges oral area 2A and sealing gasket G by effect; The structure of holding means I is used to keep above-mentioned this jointing state.That is second fluid is chimeric respectively to the annular slot 51 of the downside of the circular protrusion 21 of arranging oral area 1A and sealing gasket G to the annular slot 51 and the first fluid of the upside of the circular protrusion 11 of arranging oral area 2A and sealing gasket G.
The concrete structure of holding means I is, it is formed on first fluid and constitutes for the nut portions 67,67 on the row oral area 1A (sheet material 5) for the pair of bolts 66 among the bolt-through hole 9a of flange part 9B of row's oral area 2A by being inserted into second fluid with corresponding with pair of bolts penetration hole 9a, 9a, this holding means I has and draws by function, by bolt 66 is screwed in and fastening operation with nut portions 67, valve 2 drawn to integrated panel 1 lean on, and can keep this drawing by state.In addition, in that taking place, aging or creep causes to deal with by clamp stud 66, thereby keeping excellent sealing performance under the situation that the crimp force of each chimeric sealed department 10 descends.

Therefore, even fluid is crossed the S2 of secondary seal portion and is arrived the S1 of once sealing portion, these fluids also can be sealed by the inlet position of chimeric sealed department 10, and can not infiltrate chimeric sealed department 10 the depths, be the deep inside of telescoping groove 51,61, its advantage is, the inside of telescoping groove 51,61 is not easy the purity or the proterties of the fluid that passes through after residual influence the because of fluid or mixture, foreign matter etc.
In addition, be set at the relation of d1＞d2 between the width d1 of last circular protrusion 11 and the width d2 of last annular slot 51, preferably be set at d1 * such relation of (0.75～0.85)=d2.In addition, be set at the relation of h1＜h2 between the degree of depth h2 of the outstanding length h1 of last circular protrusion 11 and last annular slot 51.Utilize these structures, its advantage is, last circular protrusion 11 and last annular slot 51, specifically be that inside and outside two lateral circle surfaces of going up circular protrusion 11 are suppressed with the corresponding interior outside circumference that goes up annular slot 51 and connect, formed the S1 of once sealing portion of the sealability excellence of performance prevention fluid leakage, meanwhile, the taper inner peripheral surface 52a of the taper outer circumferential face 12a of upper inner ring shape push projection 12 and upper inner ring shape sealing projection 52 butt that is bound to has formed the good above-mentioned secondary seal S2 of portion thus.In addition, can down between circular protrusion 21 and the following annular slot 51, the annular slot 61 of the second sealing gasket G2 and also make such relation establishment between the shape projection 31,41 of ring up and down.
About chimeric sealed department 10, as shown in figure 16, for make internal diameter one side and external diameter one side each S1 of once sealing portion work effectively, if circular protrusion 11,31 (21,41) and annular slot 51 (61) are expressed as R1, R3, R2, R4 with respect to the radius of axis P separately, then preferably are set at and make R1＜R2 and R3＞R4 establishment.In addition, except the relation of h1＞h3 shown in Figure 16, also can be the relation of h1=h3 or h1＜h3 along the relation of the outstanding length h1 of the height h3 of the axis P direction of ring-type push projection 12,22 (13,23,32,42,3,43) and circular protrusion 11 (21,31,41).
In addition, the front end of the front end of ring- type push projection 12,13 and annular seal projection 52,53 forms the cutting shape that is unlikely to constitute the needle point fillet, i.e. inclined cutting face 12b, 13b and cutting face 52b, 53b.Utilize these structures, even a little dilatating and deformable has taken place in fluid course W1 one side in the front end of upper inner ring shape push projection 12, because of its be originally the cutting after shape, so only can form the very big section of opening midway at fluid course W1 is leg-of-mutton depression, the fluid that is present in this recess is easy to spill out, and can not produce hydrops in fact.And, the angle of release of this depression, be that the angle of inclined cutting face 12b and taper inner peripheral surface 52a is enough big, also avoided the hydrops that produces because of surface tension.In addition, the interior angle of circular protrusion 11 front ends and exterior angle have adopted the shape 11a after chamfered edge processing, therefore, being pressed into mobile can successfully carrying out to the annular slot 51 of narrower in width in, can not cut to pieces and fault such as pull.
In addition, shown in Figure 23 (a), make circular protrusion 11 form section after the chamfered edge shape 11a of portion in interior all bights of circular protrusion 11 front ends and periphery bight strengthened clearly, thereby form the structure that circular protrusion 11 enters annular slot 51 easily the closer to the thin more shape of front end.If adopt this structure, even with the suitable state of expecting a little having taken place for row's oral area 1A, 2A and the relative position of the first sealing gasket G1 when assembling, departs from first, second fluid, taper side face inside or the outside chamfered edge shape 11a of portion can play guiding function, and circular protrusion 11 is entered in the annular slot 51 effectively.Chimeric sealed department 10 in this case (S1 of once sealing portion) is with regard to becoming by the embedding part on the top of the root of circular protrusion 11 and annular slot 51 and the structure that forms.Other circular protrusion 31,21,41 and the second sealing gasket G2 in also can form this structure equally.
In addition, shown in Figure 23 (b), also the chamfered edge shape 11a of portion further can be strengthened, make the interior outside circumference of circular protrusion 11 become the tapered side side face 11a of whole inclinations, thereby form extreme the closer to the thin more shape and structure of front end.In this case, the circular protrusion 11 easier annular slots 51 that enter, following advantage is also arranged simultaneously, promptly produced circular protrusion 11 with the wide wedge effect of annular slot 51 supports, the position, top of annular slot 51 is crimped on the line way of contact or with minimum area with the root of circular protrusion 11, can realize sealing function more effectively.Other circular protrusion 31,21,41 and the second sealing gasket G2 in also can form this structure equally.
Be described in further detail chimeric sealed department 10.As Figure 15, shown in Figure 16, the angle of release of taper side face 12a, the 13a of the circular protrusion side of ring-type push projection 12,13 (angle of release of paddy portion 14,15) D is set at the value (50 °≤D °≤70 °) in 50～70 degree, and the wedge angle E of taper side face 52a, the 53a of annular seal projection 52,53 is set at value in 60～80 degree (60 °≤D °≤80 °).In addition, angle of release D and wedge angle E are set at, and angle of release D adds behind 10～20 degree that the value that obtains equals wedge angle E i.e. [D °+(10～20 °)=E °].Better value is, angle of release D is set at 69～71 degree (D °=70 ± 1 °), and wedge angle E is set at 79～81 degree (E °=80 ± 1 °), and wedge angle E is set at angle of release D+9～11 degree (E °-D °=10 ± 1 °).
In addition, the Cutting angle Ds of inclined cutting face 12b, the 13b of ring- type push projection 12,13 is set at 49～51 degree (Ds °=50 ° ± 1 °), and the inclination angle Es of front end cutting face 52b, the 53b of perisporium end 52,53 is set at 124～126 degree (Es °=125 ° ± 1 °).By such angular setting, taper outer circumferential face 12a and taper inner peripheral surface 52a and taper inner peripheral surface 13a and taper outer circumferential face 53a be butt under the line contact condition of ring-type respectively, the S2 of secondary seal portion performance sealing lip effect.
That is, taper side face 52a, the 53a of above-mentioned annular seal projection (perisporium end) 52,53 (taper inner peripheral surface 52a, taper outer circumferential face 53a) draw the direction of leaning on for row's oral area 2A for row oral area 1A and above-mentioned second fluid with respect to above-mentioned first fluid mutually---promptly draw taper side face 12a, the 13a (taper outer circumferential face 12a, taper inner peripheral surface 13a) that are set at circular protrusion 11 1 sides in above-mentioned ring- type push projection 12,13 by the wedge angle E of direction with respect to above-mentionedly drawing angle of release D by direction to go up to increase by 10～20 degree, preferably increasing the value that obtains about 10 degree or 10 degree.In addition, above-mentioned wedge angle E is set at 60～80 degree, is preferably set to about 80 degree or 80 degree.
Adopt this advantage that wedge angle E and angle of release D are set near the structure of the obtuse angle values of 90 degree to be, ring- type push projection 12,13 is drawing overhang by direction (axially) less than its radial width, intensity and rigidity have relatively been improved, both limit the expansion of annular seal projection 52,53, and can more effectively suppress himself (ring-type push projection 12,13) dilatating and deformable diametrically again.In addition, can reduce the taper side face 52a, the 53a that produce to the insertion of paddy portion 14,15 because of annular seal projection 52,53 with ring- type push projection 12,13 to the component that radially struts, this also can suppress ring- type push projection 12,13 dilatating and deformable diametrically.
The structure of above-mentioned chimeric sealed department 10 also forms according to the same manner in the downside of the first sealing gasket G1 and the second sealing gasket G2, marks corresponding reference character for corresponding position.Though the second sealing gasket G2 bore difference, its section shape and the first sealing gasket G1 are identical.But, give last second hermetic terminal t12 and the following second hermetic terminal t22 of row's oral area 1A, 2A about first and second fluid, because its, there was not fluid course in side outer Monday, so shape is slightly different with last first hermetic terminal t11 and time second hermetic terminal t21 respectively.
That is, about the last second hermetic terminal t12, its difference is, with the consecutive state of taper inner peripheral surface 33a of ring-type push projection 33 under exist perimembranous 6b in the lower end of the underpart that is used to form clack box 6.Performance guidance function when perimembranous 6b sealed department g21 on the second sealing gasket G2 is fitted among the second hermetic terminal t12 in this lower end, simultaneously, also can bring into play the function of the dilatating and deformable of the periphery wall 65 that stops the second sealing gasket G2 with taper inner peripheral surface 33a.In addition, about the following second hermetic terminal t22, its difference is, outer Monday of the ring-type push projection 43 in the outside side continued presence sheet material 5; The g22 of lower seal portion and the following second hermetic terminal t22 are being carried out when chimeric, stoping the action effect of dilatating and deformable of outer ring-like sealing projection 63 of the g22 of lower seal portion of the second sealing gasket G2 to be strengthened by taper inner peripheral surface 43a.
On the other hand, among first and second sealing gasket G1, the G2, all there are the intermediate seal pad of fluid course 7,8 in its internal diameter and outside diameter under jointing state---and promptly the first sealing gasket G1 forms following state, be that its peripheral position is the wall that outer circumferential face 55a becomes the fluid path W2 that is used to form ring-type, this fluid path W2 will be positioned at the first fluid of external diameter one side of the first sealing gasket G1 and be communicated with for the annular fluid runner 8 of row's oral area 2A for the annular fluid runner 4a of row's oral area 1A and second fluid.If make both double as of inner and outer circumferential surfaces 54a, 55a of the first sealing gasket G1 be used to form the wall of fluid course W1, W2 in this manner, then " thickness of the first sealing gasket G1 "=" annular fluid runner 3a, 7 and tubular fluid runner 4a, 8 interval ", first and second fluid is given the further miniaturization of joint of row's oral area 1A, 2A.
In addition, shown in the dummy line of Figure 14, if will on the periphery wall 65 of the second sealing gasket G2, form as one by the dismounting flange 1f of laterally projecting ring-type, then its advantage is, when give row's oral area 1A, 2A from first or second fluid, extracting the second sealing gasket G2, pull flange 1f with instrument or finger, just can be at an easy rate with its dismounting.In this case, the thickness setting of dismounting flange 1f is to give the littler value in gap of arranging between oral area 1A, the 2A than first and second fluid under the jointing state.
The following describes holding means I.As Figure 15, shown in Figure 16, the structure of holding means I is, it is used to keep following this jointing state, promptly, the first fluid of integrated panel 1 gives row's oral area 2A across first and second sealing gasket G1 for second fluid of row oral area 1A and valve 2, G2 draws mutually and leans on, meanwhile, utilizing this to draw by effect makes first fluid give the last first hermetic terminal t11 and the last second hermetic terminal t12 and first and second sealing gasket G1 of row's oral area 1A, the last sealed department g11 of G2, g21, and second fluid give following first and the second hermetic terminal t21 down of row's oral area 2A, t22, first and second sealing gasket G1, the g12 of lower seal portion of G2, g22 is chimeric respectively, forms each chimeric sealed department 10.That is, second fluid is chimeric respectively to the annular slot 51,61 of the downside of the circular protrusion 21,41 of arranging oral area 1A and first and second sealing gasket G1, G2 to the annular slot 51,61 and the first fluid of the upside of the circular protrusion 11,31 of arranging oral area 2A and first and second sealing gasket G1, G2.
The concrete structure of holding means I is, it is formed on first fluid and constitutes for the nut portions 67,67 on the row oral area 1A (sheet material 5) for the pair of bolts 66 among the bolt-through hole 9a of mounting flange portion 9 of row's oral area 2A by being inserted into second fluid with corresponding with pair of bolts penetration hole 9a, 9a, it has and draws by function, by bolt 66 is screwed in and fastening operation with nut portions 67, valve 2 drawn to integrated panel 1 lean on, and can keep this drawing by state.In addition, in that taking place, aging or creep causes to deal with by clamp stud 66, thereby keeping excellent sealing performance under the situation that the crimp force of each chimeric sealed department 10 descends.
