Referring now to Fig. 1-12,, a connector equipment 50 that shown in the figure medium source 70 is connected with a biological treatment device 90.In Fig. 1, this connector apparatus 50 comprises that a joiner 20 (seeing Figure 13 and 14) and connects valve 10 (seeing Figure 18-21).This connection valve 10 comprises a valve member 40 (seeing Figure 15-17) that is placed in one.
As shown in Figure 1, this valve member 40 comprises an end 112 that is suitable for medium source 70 connections.As shown in Figure 1, this end 112 is shown as an end that barb is housed, to connect a medium source, such as 70.Yet, also can use other interface to reach same effect.
This joiner 20 has an outlet 122, is used for being connected by medium and with a biological treatment device 90 (being such as but not limited to bioreactor).This outlet 122 illustrated in fig. 1 is a health flange (sanitary flange).Yet, can use other interface to reach same effect.
What also illustrate is that joiner 20 is used for making steam lead to one second outlet 124 of a vapour trap or condensation outlet at the disinfecting process of for example the following stated.Be placed with and export a health flange like 122 the flange type at these second outlet, 124 places.Yet can know: 124 places also can use O shape ring in second outlet.
Referring now to Figure 13 and 14,, joiner 20 comprises above-mentioned outlet 122 and 124 and be used to admit an opening 250 that is connected valve 10.Joiner 20 also comprises all flanges 252 that formed by the slit by opening 250, and every flange 252 is formed for holding a hole 22 of all lugs 12 that connect valve 10, will describe in further detail below.
More specifically illustrate as Fig. 5 and 6, connect valve 10 and place joiner 20.Referring now to Figure 18-21,, connects valve 10 formation and be of a size of a passage 260 that can hold valve member 40.The all lugs 12 that connect on the valve 10 engage with all holes 22 (seeing Figure 13) of joiner 20, and will connect valve 10 and remain in the joiner 20.The O shape sealing 14 that is arranged in slit 262 (seeing Figure 18,19 and 21) engages with the internal diameter of joiner 20, seals with the end 16 and the joiner 20 that will connect valve 10.
Referring now to Figure 15-17,, valve member 40 112 130 forms a passage 224 to the end from the end.End 130 is closed when end 112 is opened and is communicated with end 112 fluids.In addition, hole 220 is adjacent to end 130 formation and is communicated with pipeline 224 fluids.
Refer again to Fig. 5 and 6, valve member 40 places and connects valve 10.Place valve member 40 slit 272 and 274 (seeing Figure 16 and 17) O-ring seals 42 with 44 with the internal diameter that is connected valve 10 engage with the external diameter of valve member 40 be connected valve 10 and seal.
In the embodiment shown, a first jaw member 13 is fixed on to be formed at and connects in the valve 10 and surround in the hole 18 (seeing Figure 18 and 19) of a part of valve member 40.First jaw member 13 can be constructed as the U. S. Patent 5052725 of authorizing people such as Meyer is described.The function of first jaw member 13 is that valve member 40 is remained on respect to connecting on valve 10 longitudinal position fixed.
More particularly, can start first jaw member 13, so that valve member 40 is with respect to connecting valve 10 displacement longitudinally between closed position (seeing Fig. 1-6) and open position (seeing Fig. 7-12).For example, at the closed position place shown in Fig. 1-6, the part 15 of first jaw member 13 is arranged in the slit 46 that is formed at valve member 40 so that valve member 40 is held in place.
Can start first jaw member 13 by pressing down lug part 17, this makes valve member 40 indulge the edge to moving to open position with respect to connection valve 10 subsequently.The function that connects the lug 266 (seeing Figure 18) of valve 10 is that first jaw member 13 is biased to closed position.Along with first jaw member 13 is activated, can be by for example on the wings 49 of valve member 40, applying power (promptly promoting) with the valve member 40 that is along the longitudinal movement.When reaching the position of opening fully, the part 15 of first jaw member 13 is arranged in the slit 48 that is formed on valve member 40, thereby valve member 40 is fixing on the throne.
Equally, by pressing lug part 17, just can make valve member 40 be moved back into closed position to start first jaw member 13 and to make valve member 40 vertically get back to closed position by for example on wings 49, applying power (i.e. pulling) subsequently.When reaching a fully closed position, the part 15 of first jaw member 13 is positioned in the slit 46 in the valve member 40 once more, thereby makes valve member 40 be held on the throne.
Shown in an embodiment, the part 15 of first jaw member 13 tilts from ending edge, a guide edge to, thereby valve member 40 can move on to open position and not need to start first jaw member 13 from closed position.This inclined surface by part 15 is finished, this surface as a slope so that first jaw member 13 in slit 46 (see figure 5)s that when closed position moves on to open position, are easier to shift out valve member 40.Yet, (see Figure 11) in case just be contained in the slit 48 fully, thereby the words that do not start first jaw member 13 just are difficult to valve member 40 is moved on to closed position from open position at the ending edge of open position part 15.In another embodiment, can remove the gradient in the part 15 of first jaw member 13, thereby be difficult to valve member 40 is moved on to open position and moves on to closed position from open position from closed position if do not start first jaw member 13.
Referring to Fig. 6 and 12, valve member 40 is slided to be fixed on by all arms 100 that connect valve 10 and connects in the valve 10.All arms 100 can be along the longitudinal movement and comprise and extend all most advanced and sophisticated 102 of the external diameter that inserts the connection valve 10 in the joiner 20 with respect to connecting valve 10.Therefore, when valve member 40 was arranged in joiner 20, the tip 102 of arm 100 contacted with the internal diameter of joiner 20, and radially inwardly biasing of arm 100.In such layout, the inner 104 of arm 100 places a slit 106 that is formed on the valve member 40.All inner 104 are arranged in slit 106, and therefore valve member 40 vertically moves between the end 108 and 110 of slit (seeing Figure 16 and 17) only.Therefore, valve member 40 can not be moved to beyond the complete closed position (see figure 6), because all arms 100 contact with the end of slit 110.
When valve member 40 during in closed position shown in Figure 6 material flow out from the outlet 122 of joiner 20, enter intersection 121 through piping 120, arrive outlet 124 (it also is possible flowing backwards) through piping 222 again.Yet, since the inner end 16 that connects valve 10 against joiner 20 by O-ring seals 14 sealings, and the end 130 of valve member 40 is against connecting valve 10 by O-ring seals 44 sealings, do not have the material can flowing into pipeline 224 and flow to the end 112 of valve member 40.
On the contrary, the end 130 of valve member 40 longitudinally is shifted and enters the pipeline 222 of joiner 20 through intersection 121 when valve member 40 is in open position shown in Figure 12, thereby O-ring seals 44 is engaged in the internal diameter of the pipeline 222 of joiner 20.In addition, because present valve member 40 is sealed in joiner 20 and just in time is adjacent to intersection 121 by O-ring seals 42, therefore the pipeline 224 in the valve member 40 is connected by hole 220 (the seeing Figure 15-17) fluid that is formed in the valve member 40 with intersection 121.
In the topology layout of opening (open configuration) of this valve member 40, material can flow out from the outlet 122 of joiner 20, enter intersection 121 through piping 120, again through being formed on the outlet 112 (refluence also is possible) that hole 220 (seeing Figure 15-17) in the valve member 40 and pipeline 224 arrive valve members 40.Yet, because the end 130 of valve member 40 by the internal diameter sealing of O-ring seals 44 against the pipeline 222 of joiner 20, does not have the material can flowing into pipeline 222 and flow to the end 124 of joiner 20.
In a kind of similar methods, valve member 40 can longitudinally be shifted and get back to the closed position (see figure 6), thereby the fluid that rebulids between pipeline 120 and 222 is communicated with, and cuts off the connection with the pipeline 224 of valve member 40.
