Fig. 6 is the axial sectional view of main body.
In the accompanying drawings, identical parts use identical reference character.Accompanying drawing is not according to the scale of reality.
Embodiment
To combine accompanying drawing that the utility model is described further below.
Fig. 1 has clearly illustrated the erection drawing of gland type joint 10 that is used to connect fluid line and reaction pipe according to the utility model.Joint 10 comprises main body 1.This main body 1 comprises and is used for forming first end 11 that is connected with the fluid line (not shown), and is used for forming second end 7 that is connected with end cap 4.Be provided with the inner chamber 6 that runs through main body in the inside of main body 1.The fluid line and first end are preferably and are tightly connected, and for example FERRULETYPE connects, thereby can fluid, the for example reaction gas from the fluid pipeline be input in the inner chamber 6.
End cap 4 (as shown in Figure 3) for example can be provided with internal thread, is used for outside thread on second end 7 with main body 1 and forms and engage, and black box is pressed in the inner chamber 6.End cap 4 is preferably six square nuts.In addition, end cap 4 is equipped with through hole with black box, makes reaction pipe 5 therefrom to pass and to extend in the cavity 6.Fig. 2 shows reaction pipe 5, and it is rigidity roughly normally.
Black box according to the utility model comprises elastic washer 2 and rigidity packing ring 3.Wherein, elastic washer 2 bears against on the first step 13 (more being clearly shown that like Fig. 6) in the inner chamber 6.One end of rigidity packing ring 3 and elastic washer 2 adjacency, the other end and end cap 4 adjacency.Elastic washer 2 is preferably processed by teflon.Rigidity packing ring 3 is preferably processed by stainless steel.In a preferred embodiment, adopt Austenitic Stainless Steel to process rigidity packing ring 3, adopt teflon to process elastic washer 2 simultaneously.Understand needs that the quantity of elastic washer 2 and rigidity packing ring 3 can be as the case may be and suitably selecting in addition easily.
In operation, fluid line is engaged with first end 11 of gland type joint 10.Then reaction pipe 5 is inserted in the inner chamber 6, is inserted in elastic washer 2 and rigidity packing ring 3 afterwards successively.Compress rigidity packing ring 3 through end cap 4 at last.Inwardly move to force rigidity packing ring 3 through turn-knob end cap 4; Just can make rigid pad circle 3 extruding elastic washers 2; And then make elastic washer 2 produce deformation, and cause the external diameter of its internal diameter and reaction pipe 5 to closely cooperate, the internal diameter of the appropriate section of its external diameter and inner chamber 6 closely cooperates simultaneously.Thus, formed good seal action at elastic washer 2 places.Like this, can outwards not reveal by the fluid that fluid line provided, and can only enter into reaction pipe 5 to react.When needs take out reaction pipe 5, can outwards unscrew end cap 4, thereby eliminate the active force that rigidity packing ring packing ring 3 puts on the elastic washer 2.This moment, elastic washer 2 resiled.In this case, reaction pipe 5 can separate with black box, so can successfully take out reaction pipe 5.
Have the gland type joint 10 of this novel black box through use, extraordinary sealing effect can be provided.Through experimental verification, in the gland type joint 10 according to the utility model, its high pressure resistant air pressure can reach 3 MPas, and high temperature resistant temperature can reach 100 degrees centigrade, and the pulse vibratory test can reach ten million circulation, reveals test air pressure and is not less than 2.2 MPas.Simultaneously, reaction pipe also can load and unload freely.
As shown in Figure 1, according to a preferred embodiment of the utility model, first step 13 has the inner conical inclined-plane, and the first end 21 of adjacent elastic washer 2 has external conical shape inclined-plane (as shown in Figure 5).This design has improved the sealing between elastic washer 2 and the first step 13.Alternatively, as shown in Figure 5, the opposite second end 22 of elastic washer 2 also has the external conical shape inclined-plane, is used for inner conical inclined-plane on the adjacent first end 31 with rigidity packing ring 3 and forms and cooperate (as shown in Figure 4).So just further improved the compressional deformation ability of elastic washer 2, made it under less power extruding, produce bigger deformation, thereby produce better being sealed and matched.
Preferably, the external diameter of the internal diameter of elastic washer 2 and reaction pipe 5 is suitable.Simultaneously, the internal diameter of the appropriate section of the external diameter of preferred elastomeric packing ring 2 and inner chamber 6 is suitable.Term " suitable " means between two parts no gap or has only very little gap.As above optimal way makes elastic washer 2 under small deformation, just can produce good sealing effect, has not only strengthened sealing, can also slow down elastic washer 2 loss in use.
Inner chamber 6 also can be provided with second step 12, and it is used for the end of breasting reaction pipe 5 between first end 11 and first step 13 of main body 1.So just, can play the effect of reaction pipe location in operation.
As shown in Figure 4, the second end of rigidity packing ring 3 has plane type flange 32, and this flange 32 for example can be contained in the locating slot 41 in the inner chamber of end cap 4, thereby can bear the active force that is applied by end cap 4, and and then this power is passed to elastic washer 2.
Gland type joint according to the utility model can be widely used in the pipeline connection of any fluid-solid reaction device.It is particularly useful for the gas-solid phase reaction device, for example in the micro anti-evaluation device of evaluate catalysts performance.At this moment, fluid line is used to provide gas, loading catalyst and reacting in reaction pipe.
Above reference preferred embodiment the utility model is described, but the protection domain of the utility model is not restricted to this, all technological schemes in any scope that falls into claim are all in the protection domain of the utility model.Under the situation of the scope that does not break away from the utility model, can carry out various improvement and can replace parts wherein it with equivalent.Especially, only otherwise have structural hazard, each item technical characteristics of being mentioned among each embodiment all can combine by any-mode.
