Preferably, the material of this strip can be iron wire or steel wire, the steel wire particularly formed by spring steel, stainless steel.

Preferably, the matrix in above each embodiment of the present disclosure can be the sealing matrix being provided with kapillary.

(installation process example)

The example of the process that the interconnecting piece according to embodiment of the present disclosure is installed in the equipment of such as fluid level transmitter or pressure remote transmission device is described below in conjunction with Figure 13.

As shown in Figure 13, the matrix 1 shown in Fig. 3 and Fig. 4 such as, it is provided with kapillary 6 by welding B sealing, other functional units 5 that the other end of kapillary 6 is connected in fluid level transmitter or pressure remote transmission device by welding A. In addition, the such as mounting flange 2 shown in Fig. 3 and Fig. 4 was just enclosed on kapillary 6 be soldered to matrix 1 and other functional units 5 at kapillary 6 before, and can be free to slide on kapillary 6 in the installation processes such as such as welding, until matrix 1 is inserted in mounting flange 2. Matrix 1 is being inserted in the process in mounting flange 2, can first interconnecting piece 4 be enclosed within the first groove 11 on matrix 1, to be inserted in mounting flange 2 with the matrix 1 of interconnecting piece 4 subsequently, and annulus 3(Figure 13 that the first groove 11 making the 2nd groove 21 and matrix 1 that interconnecting piece 4 is accommodated in mounting flange 2 is formed does not illustrate) in, to prevent mounting flange 2 and matrix 1 depart from and damage equipment or injury mutually. Certainly, in this process, it is necessary to the opening size of interconnecting piece 4 is greater than the diameter of kapillary 6. Owing to the diameter of kapillary 6 is usually very little, therefore this requirement is that appearance is readily accessible.

As a comparison, the installation process of existing V shape collar is described below with reference to Fig. 2 A and 2B.

As shown in Figure 2 A, existing V shape collar is closed, and as shown in Figure 2 B, a series of has the elasticity part of opening and make V shape collar have elasticity by processing on thin-walled. In process shown in fig. 13, it is possible to use V shape collar is as interconnecting piece. Wherein, V shape collar was just enclosed on kapillary 6 be soldered to matrix 1 and other functional units 5 together with mounting flange 2 at kapillary 6 before, and was free to slide on kapillary 6, until being inserted in mounting flange 2 by matrix 1.

Thinner owing to organizing the wall portion of the elasticity part of forming V-shape collar, therefore V shape collar easily damages in the process being free to slide. Once V shape collar damages, then making the V shape collar that more cannot renew while keeping the welding of kapillary 6 and other parts due to the close-shaped of V shape collar, installation and use are caused very big inconvenience by this.

And when the interconnecting piece that use provides according to embodiment of the present disclosure, owing to interconnecting piece has opening, it is possible to be enclosed within any time in installation process on kapillary 6, above-described inconvenience therefore can not be caused.

In addition, the structural rate V shape collar of the interconnecting piece provided according to embodiment of the present disclosure is more durable, and cost is cheaper simultaneously.

Describe the structure of traditional snap ring below with reference to Fig. 1, and the advantage of the interconnecting piece according to embodiment of the present disclosure compared to traditional snap ring is described.

In the annulus of the annular that traditional snap ring of the circle shown in Fig. 1 is formed by the first groove of circle and the 2nd circular groove for being accommodated in when the first element is connected to two element. When the traditional snap ring shown in Fig. 1 is accommodated in the annulus of annular, the inner side of snap ring contacts the face in the first groove in each position, and the outside of snap ring contacts the face in the 2nd groove in each position, to prevent the first element and two element depart from mutually.

Therefore, the wire diameter (that is, forming the thickness of the material of snap ring) of traditional snap ring is more much bigger than the wire diameter of the interconnecting piece provided according to embodiment of the present disclosure. Such as, the wire diameter of the interconnecting piece provided according to embodiment of the present disclosure can be only about the 1/5 of the wire diameter of traditional snap ring of same use.

Therefore, compared to traditional snap ring, on the one hand, only needing to form more shallow endless groove on the first element and two element can hold according to the interconnecting piece that embodiment of the present disclosure provides, such as, the degree of depth of the endless groove required for the interconnecting piece provided according to embodiment of the present disclosure can be only 1/3 of the degree of depth required for traditional snap ring.

On the other hand, it is easier to when necessary be destroyed intentionally according to the interconnecting piece that embodiment of the present disclosure provides, even if making after the first element is connected to two element, by destroying interconnecting piece intentionally, the first element can also be separated with two element, to carry out keeping in repair, the suitable process such as replacing.

Specifically, such as, in shown in figs. 3 and 4 embodiment of the present disclosure, the intensity of interconnecting piece 4 can be configured to, when interconnecting piece 4 is contained in annulus 3, if the reactive force applied between matrix 1 and mounting flange 2 along the axis direction of annulus 3 between matrix 1 and mounting flange 2 is less than predetermined threshold, then interconnecting piece 4 does not depart from from annulus 3, thus maintains the connection relation between matrix 1 and mounting flange 2. And, the intensity of interconnecting piece 4 can also be configured to, when aforementioned reactive force is more than or equal to predetermined threshold, namely, when attempting the destruction by having a mind to and matrix 1 be separated with mounting flange 2, interconnecting piece 4 destroys and lost efficacy due to the shear-stress produced by the first groove 11 and the 2nd groove 21, thus matrix 1 and mounting flange 2 can be separated from one another when destroyed.

This predetermined threshold can be such as value between the scope of 200 to 1200 pounds, it is preferred that the value between the scope of 300 to 600 pounds (LB). But, this predetermined threshold is not limited to this, and predetermined threshold can also be chosen as other suitable values according to practical situation by those of ordinary skill in the art.

It should be understood by one skilled in the art that, it is possible to configured the intensity of interconnecting piece 4 by modes such as the wire diameter of change interconnecting piece, cross-sectional shapes.

And for the such as traditional snap ring shown in Fig. 1, owing to its line diameter ratio is much larger according to the interconnecting piece of embodiment of the present disclosure, so when the first element is separated with two element, destroying the required shear-stress applied of tradition snap ring and also want big very most, this easily causes damaging the first element or two element while being separated with two element by the first element. And power according to interconnecting piece required applying when destroyed of embodiment of the present disclosure is much little, make to reduce the possibility damaging the first element or two element with two element while being separated by the first element to a great extent, it is ensured that while being separated with two element by the first element, do not damage the first element and two element.
