The model utility content
The purpose of this utility model is to provide a kind of SF6 gaseous state monitoring air chamber connection set that makes things convenient for installation, good airproof performance and can avoid the rigidity contact to damage, and solves the shortcoming that prior art exists.
The utility model adopts following technological scheme to realize:
A kind of SF6 gaseous state monitoring air chamber connection set, this air chamber connection set links to each other with the inflation inlet that the SF6 gaseous state detects air chamber, it is characterized in that, described air chamber connection set is four-way shape, one of them passage is the Self-sealing valve suction port, in the air chamber connection set body spring thimble mechanism is set, described spring thimble mechanism is used for carrying out bidirectional flexible with the thimble of the inflation inlet of air chamber and contacts.
Further, described spring thimble mechanism comprises elastic collar, movable thimble, Returnning spring and spring seat, described elastic collar is installed in the opening inboard of Self-sealing valve suction port, described movable thimble passes spring seat and elastic collar successively, also have a circle spacing preiection on the middle part outer circumferential face of movable thimble, wear between described spacing preiection and the spring seat and be connected with Returnning spring.
Further, have groove on the surface of contact of described spacing preiection and air chamber connection set inner body wall, be provided with the first seal ring in the described groove.
Further, also comprise second and third, four seal rings, described the second seal ring is installed in the groove of air chamber connection set body front end, described third and fourth seal ring is installed in the inflation inlet inwall of air chamber connection set.
The useful technique effect that the utility model possesses is: be provided with spring thimble mechanism in the Self-sealing valve suction port of air chamber connection set, so that thimble has certain mobility, subdued the error of the fixed thimble that processing, assembling etc. cause, and can eliminate well owing to the long-time on-the-spot damage that causes primary equipment inflation inlet Self-sealing valve of installing; A plurality of seal rings guarantee that installation process substantially without the SF6 leakage, guarantees the reliable sealing of sealing in this joint of equipment run duration; Handsome in appearance, the on-the-spot safe ready of installing.
Description of drawings
Fig. 1 is the front view of the utility model air chamber connection set.
Fig. 2 is the left view of the utility model air chamber connection set.
Fig. 3 is that (analysing and observe) figure is amplified in the part of the Self-sealing valve of the utility model air chamber connection set.
Embodiment
By following description to embodiment; to more help public understanding the utility model; but can't the specific embodiment that the claimant is given be considered as the restriction to technical solutions of the utility model, any definition to parts or technical characteristics change and/or to overall structure do form and immaterial conversion all should be considered as the protection domain that the technical solution of the utility model limits.
As depicted in figs. 1 and 2, this air chamber connection set links to each other with the inflation inlet that the SF6 gaseous state detects air chamber, the air chamber connection set is four-way shape, four passages connect respectively dew point transmitter IV, pressure transmitter V, Self-sealing valve suction port II and Self-sealing valve relief opening III (reservation inflation inlet), whole air chamber is in design, all whole consideration is carried out in sealing in processing and the factory inspection process, thereby except the Self-sealing valve suction port, other joint can both guarantee good sealing effect, and air chamber and air chamber connection set joint encapsulation process have just become the emphasis of SF6 air chamber design.In the air chamber connection set body spring thimble mechanism is set, spring thimble mechanism is used for carrying out bidirectional flexible with the thimble of the inflation inlet of air chamber and contacts, the bidirectional flexible contact can be eliminated well owing to the long-time on-the-spot damage that causes primary equipment inflation inlet Self-sealing valve of installing, thereby guarantees the safety of primary equipment.
As shown in Figure 3, spring thimble mechanism comprises elastic collar 3, movable thimble 6, Returnning spring 5 and spring seat 4, elastic collar 3 is installed in the opening inboard of Self-sealing valve suction port, movable thimble 6 passes spring seat 4 and elastic collar 3 successively, also have a circle spacing preiection 11 on the middle part outer circumferential face of movable thimble 6, wear between spacing preiection 11 and the spring seat 4 and be connected with Returnning spring 5.Because Returnning spring 5 is be socketed in movable thimble 6 outer circumferential, therefore so that movable thimble 6 has certain mobility, subdued the error of the fixed thimble that processing, assembling etc. cause, and can eliminate well owing to the long-time on-the-spot damage that causes primary equipment inflation inlet Self-sealing valve of installing.Have groove on the surface of contact of spacing preiection 11 and air chamber connection set body 2 inwalls, be provided with the first seal ring 7 in the groove, the second seal ring 1 is installed in the groove of air chamber connection set front end, and the 3rd seal ring 8 and the 4th seal ring 9 are installed in the inflation inlet inwall of air chamber connection set.Adopt double seal between the suction port of air chamber connection set and the inflation inlet, circumferential O shape the first seal ring 7, the 3rd seal ring 8 and the 4th seal ring 9 guarantee that safety is without gas leakage in the installation process, and O shape second seal ring 1 of end face has excellent sealing reliability; Circumferential seal circle and end-face seal ring acting in conjunction can improve the device security performance greatly.Need to tighten mounting nuts 10 for on-the-spot, the movable thimble 6 of this Self-sealing valve structure just can realize that bidirectional flexible contacts with the thimble of apparatus body, can eliminate well owing to the long-time on-the-spot damage that causes primary equipment inflation inlet Self-sealing valve of installing, thus the safety of the equipment of assurance.
