(installation process example)
Describe connected element according to embodiment of the present disclosure below in conjunction with Figure 13 and be installed in example such as the process in the equipment of fluid level transmitter or pressure remote transmission device.
As shown in Figure 13, for example by welding B capillary tube 6 is installed hermetically in the matrix shown in Fig. 3 and Fig. 41, the other end of capillary tube 6 is connected to other functional units 5 in fluid level transmitter or the pressure remote transmission device by welding A.In addition, for example the mounting flange shown in Fig. 3 and Fig. 42 just was enclosed on the capillary tube 6 before capillary tube 6 is soldered to matrix 1 and other functional units 5, and in such as installation processes such as welding, can be free to slide at capillary tube 6, till being inserted into matrix 1 in the mounting flange 2.In the process that matrix 1 is inserted in the mounting flange 2, can earlier connected element 4 be enclosed within first groove 11 on the matrix 1, the matrix 1 that will have connected element 4 subsequently is inserted in the mounting flange 2, and it is not shown to make that connected element 4 is accommodated among first groove, 11 formed annulus 3(Figure 13 of second groove 21 of mounting flange 2 and matrix 1) in, break away from and damage equipment or injury personnel mutually to prevent mounting flange 2 and matrix 1.Certainly, in this process, need the opening size of connected element 4 greater than the diameter of capillary tube 6.Because the diameter of capillary tube 6 is very little usually, so this requirement is easy to reach.
The installation process of existing V-arrangement collar is described below with reference to Fig. 2 A and 2B as a comparison.
As shown in Fig. 2 A, existing V-arrangement collar seals, and as shown in Fig. 2 B, by making the V-arrangement collar have elasticity at a series of elastic components with opening of thin-walled processing.In the process shown in Figure 13, also can use the V-arrangement collar as connected element.Wherein, the V-arrangement collar just was enclosed on the capillary tube 6 before capillary tube 6 is soldered to matrix 1 and other functional units 5 with mounting flange 2, and was free to slide at capillary tube 6, till being inserted into matrix 1 in the mounting flange 2.
Because the wall portion of the elastic component of composition V-arrangement collar is thinner, so the V-arrangement collar damages in the process that is free to slide easily.In case the V-arrangement collar damages, then owing to the close-shaped and feasible V-arrangement collar that can't more renew in the welding that keeps capillary tube 6 and miscellaneous part of V-arrangement collar, this is to installing and using and caused very big inconvenience.
And under the situation that the connected element that provides according to embodiment of the present disclosure is provided, because connected element has opening, can in installation process, be enclosed within any time on the capillary tube 6, therefore can not cause above-described inconvenience.
In addition, the structure of the connected element that provides according to embodiment of the present disclosure is more durable than V-arrangement collar, and cost is cheaper simultaneously.
Describe the structure of traditional snap ring below with reference to Fig. 1, and explanation is according to the embodiment's of the present disclosure connected element advantage than traditional snap ring.
Traditional snap ring of the circle shown in Fig. 1 is used for being accommodated in the annulus of the ring that second groove by first groove of circle and circle forms when first element is connected to second element.When the traditional snap ring shown in Fig. 1 is accommodated in the annulus of ring, the inboard of snap ring contacts the face in first groove in each position, and the outside of snap ring contacts the face in second groove in each position, breaks away from mutually to prevent first element and second element.
Therefore, it is directly much bigger that the line of traditional snap ring footpath (that is, forming the thickness of the material of snap ring) wants the line of the connected element that beguine provides according to embodiment of the present disclosure.For example, the line of the connected element that provides according to embodiment of the present disclosure footpath can only be same use traditional snap ring the line footpath about 1/5.
Therefore, than traditional snap ring, on the one hand, only need can hold the connected element that provides according to embodiment of the present disclosure at first element and the more shallow annular slot of second element formation, for example, the degree of depth of the needed annular slot of connected element that provides according to embodiment of the present disclosure can only be 1/3 of the traditional needed degree of depth of snap ring.
On the other hand, the connected element that provides according to embodiment of the present disclosure is easier to be destroyed wittingly where necessary, even make after first element is connected to second element, also can first element be separated with second element by destroying connected element wittingly, with keep in repair, suitable processing such as replacing.
Specifically, for example in the embodiment of the present disclosure shown in Fig. 3 and Fig. 4, the intensity of connected element 4 can be configured to, when connected element 4 is contained in the annulus 3, if at the active force that between matrix 1 and mounting flange 2, applies along the axial direction of annulus 3 between matrix 1 and the mounting flange 2 less than predetermined threshold, then connected element 4 does not break away from from annulus 3, thereby keeps the annexation between matrix 1 and the mounting flange 2.And, the intensity of connected element 4 can also be configured to, when aforementioned active force during more than or equal to predetermined threshold, namely, when attempting by the destruction of having a mind to matrix 1 to be separated with mounting flange 2, connected element 4 lost efficacy owing to being destroyed by the shearing stress of first groove 11 and 21 generations of second groove, thereby matrix 1 and mounting flange 2 can be by separated from one another under situation about not being destroyed.
This predetermined threshold can be for example value between the scope of 200 to 1200 pounds, the preferably value between the scope of 300 to 600 pounds (LB).Yet this predetermined threshold is not limited thereto, and those of ordinary skills also can be chosen as other suitable values with predetermined threshold according to actual conditions.
It will be understood by those skilled in the art that can be by changing connected element modes such as line footpath, sectional shape dispose the intensity of connected element 4.
And for for example traditional snap ring shown in Fig. 1, because its line footpath beguine is a lot of greatly according to embodiment's of the present disclosure connected element, so when first element is separated with second element, it is also greatly very most to destroy the required shearing stress that applies of traditional snap ring, this cause easily with first element with damage first element or second element when second element separates.And it is little a lot of according to connected element required power that applies when destroyed of embodiment of the present disclosure, make and to have reduced to a great extent with first element and the possibility of damaging first element or second element when second element separates, can guarantee with first element with do not damage first element and second element when second element separates.
