The specific embodiment
Following according to Fig. 2～Fig. 4, a kind of preferred forms of the present invention is described.
Figure 1 shows that a closure member representing the prior art state of development.As can be seen, closure member has a closure body 1, wherein is provided with passage 1.1, and this passage seals with a fuse element 2.Fuse element is a kind of melting welding scolder, is placed in the passage 1.1 in the whole section scope of passage 1.1, and shows very big thickness.
In Fig. 4 a and Fig. 4 b, also show in addition and be installed in a kind of closure member of representing the prior art state of development that uses in the fluid coupling.A kind of like this closure member in the fluid coupling has certain starting to lag behind, and causes the about 50K of working medium overtemperature, and overtemperature is relevant with the firing rate of working medium.This means that the temperature of fluid coupling working medium is approximately than the high about 50K of the temperature rating of melting welding scolder.
Figure 2 shows that according to closure member of the present invention, is the installation site scheme drawing before throwing off shown in Fig. 2 a, is the view of finishing after the disengagement shown in Fig. 2 b.
Closure body 1 has a matrix 6, and this matrix is provided with an opening 6.1.Opening 6.1 is got the form of cylindrical bore, and it is placed into as blind hole or as unfair hole.Insert a sleeve 3 in the end that this blind hole is open.End on the blind hole opposite is the water conservancy diversion through hole that opening 6.1 and external environment condition are connected.
Sleeve 3 has a columniform through hole 3.1, this through hole and opening 6.1 coaxial alignments.In addition, sleeve 3 also has a support member 3.4, utilizes these support member 3.4 sleeves 3 to insert opening 6.1 at positive diameter in greater than the depression of opening 6.1.In Fig. 5, can clearly be seen that, between matrix 6 and support member 3.4, inserted a sealing member 7 that is designed to O-ring seals.At the another side of support member, matrix 6 is crimping to the inside, thereby produces the edge (seeing arrow) of a contraction, and sleeve is fastened in the matrix 6.
In sleeve 3, inserted a bolt 4, that is to say that the neighboring 4.1 of bolt 4 is opposed with the inside circumference 3.2 of sleeve 3.Insert a fuse element 2 made from the melting welding scolder between neighboring 4.1 and inside circumference 3.2, before reaching fusion temperature, sleeve 3 interconnects (installation site) with bolt 4.
In the installation site, closure member is that liquid is close.Sleeve 3 is by means of sealing member 7 and matrix 6 sealing and thermal insulations, and the liquid of bolt 4 close also be to be welded together by fuse element 2 and sleeve 3.Surpass when predesignating the range of temperatures value, the fuse element fusing disconnects being connected with a joggle between bolt 4 and the sleeve 3.Like this, for example because the superpressure of the cavity inside that is closed, bolt 4 may release sleeve 3, and move in the cavity 6.1 in the matrix 6 (finish disengagement after state) fully.In this state, in the head scope of matrix 6, there is one to pass through closure member, water conservancy diversion through through hole 6.2 connects, as shown in the figure, this head scope is designed to blind bolt, enters the inner space of the cavity that originally was closed by the cylindrical hole 3.1 in opening in the matrix 6 6.1 and the sleeve 3.
Like this, bolt 4 just has been added a bolt head 4.4, and it protrudes from the neighboring 4.1 of bolt 4, is positioned at the end face of sleeve 3, for bolt 4 has been preset a Way out 5.
As shown in Figure 5, in a preferable version, between bolt head 4.4 and that part, inserted a pressure spring 9 in the face of the opening 6.1 in the matrix 6.When 2 fusings of the fuse element between bolt 4 and sleeve 3, this pressure spring pushes in the cavity 6.1 ejecting fully the through hole 3.1 of bolt 4 in sleeve 3.Obviously, also can use another pressure element to replace pressure spring, can add or replace a pulling force component in addition, for example be fixed in the matrix 6 and on the bolt 4, allow pulling force affact on the bolt along Way out 5.According to the version shown in Fig. 5, bolt 4 is solid cylinders, and the cavity 6.1 that holds pressure spring 9 communicates with external environment through a boring, therefore, under disengaged condition, medium can flow out (being right-to-left stream) in Fig. 5 from original osed top chamber.
In Fig. 5, represent, bolt more than center line, be in disengaged condition and at center line with the next installation site that is in.Corresponding therewith, pressure spring 9 is in relaxed state basically more than center line, and at center line with the next state of tightening that is in fully.Matrix 6 is designed to the locking bolt, and as shown in the figure, it is furnished with outside thread 6.3, so that screw in inclosure.Corresponding therewith, matrix also can have one outer-hexagonal edge or interior hexagonal edge in its head scope, so that make the bolt up instrument.
As shown in Fig. 2 and Fig. 3, bolt 4 has a blind hole 4.2, allows it almost completely pass and only do not pass leak free bottom range.The leg of hollow bolt 4 is thinner, can very fast heating, therefore can be transmitted to the melting welding scolder to the heat in bottom range rapidly.For this reason, the copper that bolt 4 the most handy thermal conduction ratinies are high becomes.This requirement is equally applicable to sleeve 3, promptly preferably is made of copper thin walled cylinder body, so that the outside, for example needs heat in sealed hollow 10 peripheral extent to be close to and is sent to the melting welding scolder without delay.Because sleeve 3 plays a role in insulation to matrix 6 by means of sealing member 7 heatings, so have only heat seldom to be transmitted to matrix 6 from sleeve 3, in other words, sleeve can not cooled off by matrix.Therefore, the disengagement time is very short.
No matter be that sleeve or bolt can be made with tinned copper.It shown in Fig. 3 the intermediateness of making according to closure member of the present invention.According to the optimum process method of corresponding manufacturing closure member, at first make end sealing and the unlimited hollow body of the other end to sleeve 3, make cylinder block in other words, establish a blind hole, keep a tube end 3.3.
Sleeve 3 is vertical basically, allows a unlimited end up, and osed top one end (the tube end 3.3) down.The melting welding scolder is placed in the cavity, that is to say in the blind hole that places sleeve, forming a melting welding scolder cylinder 2.1 at the bottom of the tube on 3.3.And then, bolt 4 is inserted in the cavity, that is to say to be inserted in the blind hole, guarantee that its osed top end face is immersed in the melting welding scolder cylinder 2.1.The volume of the melting welding scolder that the immersion of bolt 4 is partly discharged is discharged from and changes over to the intermediate space between bolt 4 and the sleeve 3, that is to say, changes between the inside circumference 3.2 of the neighboring 4.1 of bolt and sleeve.At this place, the melting welding scolder is connected with a joggle bolt 4 and sleeve 3 by solid welding, and they are sealed mutually.As a supplement or alternative scheme, also can be in the front, for example between the end face of the sleeve 3 on the bolt head 4.4 of bolt 4 and opposite, seal.
And then, the tube end 3.3 of sleeve 3, separated, for example separate with mach method.Like this, formed through hole 3.1 in sleeve, under disengaged condition not, this through hole is with bolt 4 sealings.
As shown in Figure 3, sleeve 3 can have a support member 3.4, generates when being connected with a joggle between bolt 4 and sleeve 3, and sleeve 3 utilizes support member 3.4 to be fixed in the instrument 8.As mentioned above, support member 3.4 also is used for sleeve 3 and matrix 6 are sealed simultaneously.
The a spot of melting welding scolder of a design-calculated closure member needs in illustrated embodiment, needs 105mm approximately according to the present invention
3The melting welding scolder.
A kind of fluid coupling has been shown among Fig. 4 C, in its housing, has used closure member mentioned above.Plunging joint has a working space 20, need to be equivalent to leak free cavity 10.Working space is surrounded by the plunging joint shell directly or indirectly, and wherein, shell bears the pressure of plunging joint working medium.Owing to be designed to the packing into of closure member of blind bolt as shown in the figure, closure member makes the load of working medium enter through hole on the closure shell in the front, and the temperature of working medium is sent to closure member.Working medium surpasses when predesignating ultimate temperature, the melting welding solder fusing in the closure member, closure member insert wherein opening almost its whole transversal and scope in (except the leg of matrix) open wide, thereby working medium flows out from plunging joint.
A kind of better simply enforcement pattern of closure member can be saved the sleeve 3 shown in Fig. 2 to Fig. 4 according to the present invention, allows bolt 4 closure body 1 of directly packing in a through hole.In this case, fuse element 2 directly is connected bolt 4 with closure body 1, that is fuse element 2 is placed between the inside circumference of the neighboring of bolt 4 and closure body 1 through hole with the shape that forms a ring.In this enforcement pattern, material as bolt preferably adopts a kind of like this material, it can be welding in the melting welding scolder in the closure body 1 reliably by fuse element on the one hand, can send the end face that the hot-fluid of big heat starts from it to the melting welding scolder again simultaneously on the other hand.According to a kind of special enforcement pattern, bolt 4 can adopt a kind of material softening under the disengagement temperature of closure member.But,, particularly place the melting welding scolder of periphery throwing off mechanical connection between bolt and the closure body by fusing under the temperature of predesignating for throwing off a bit being that function plays a decisive role reliably.
In order to compare with implementing pattern shown in Fig. 2, finish and throw off the medium that the back forms and can obtain a bigger fluid section, when design, preferably allow the through hole in the sleeve 3 that a bigger section is arranged.Through hole in the sleeve 2 preferably has 7.5mm or bigger diameter, and the diameter of 7.8mm is particularly arranged, and can form a half-way house preferably between size and the minimum fluid openings in packing into of maximum like this.In order to allow fuse element 2, particularly the melting welding scolder as much as possible more in depth enters the inner space, for example enters fluid coupling, and whole closure member will have the length that is equal to or greater than 29mm.
