Fig. 1 is the half sectional view of high voltage-resistant bi-directional rotating seal ring peculiar to vessel in prior art;
Fig. 2 is the half sectional view of high voltage-resistant bi-directional rotating seal ring peculiar to vessel of the present utility model.
In figure, 21 is metal shell, and 22 is PTFE lip-type packing, 23 be original support ring 23,24 is original O RunddichtringO, and b is metal frame, a is original sealing lip, and 1 is shell, and 2 is end cap, 3 is the first support ring, and 4 is the second support ring, and 5 is spring, 6 is sealing lip, and 7 is an O RunddichtringO, and 8 is the 2nd O RunddichtringO, 9 is rectangular seal, and 10 is the first fastening piece, and 11 is the second fastening piece.
Embodiment
In order to understand the utility model better, below in conjunction with specific embodiment, the utility model is explained in detail.But, obviously can carry out different modification and remodeling to the utility model and not exceed the wider spirit and scope of the utility model of appended claims.Therefore, following examples have exemplary and hard-core implication.
Embodiment:
A kind of high voltage-resistant bi-directional rotating seal ring peculiar to vessel, it is combined type packing ring, namely sealing circle is by the shell 1 of metal, end cap 2, first support ring 3, second support ring 4 and the O RunddichtringO 7 with the shaping sealing lip 6 of the PTFE turning of spring 5 and other auxiliary seals, 2nd O RunddichtringO 8, rectangular seal 9 and the first fastening piece 10, second fastening piece 11 forms, its medi-spring 5 is arranged on the shaping sealing lip of PTFE turning 6, one O RunddichtringO 7 is arranged on metal shell 1, 2nd O RunddichtringO 8 is arranged on the second support ring 4, then by sealing lip 6, first support ring 3, second support ring 4 and rectangular seal 9 are according to after in Fig. 2, order loads the shell 1 of metal, the first fastening piece 10 and the second fastening piece 11 is used to be carried out being connected with the shell 1 of metal by end cap 2 and fastening.
The sealing lip 6 that in Fig. 2, three PTFE turning is shaping is divided into two groups by different direction, seals respectively, realize the main dynamic bidirectional rotary seal function of seal ring to the sealing medium on both sides; Two the O RunddichtringOs 7 being arranged on shell 1 outside of metal realize the static sealing between two-way sealing ring and apparatus casing; The 2nd O RunddichtringO 8 in Fig. 2 and three rectangular seals 9 realize between three sealing lips 6 and the first support ring 3, second support ring 4, end cap 2 respectively, and second static sealing between support ring 4 and the shell 1 of metal, guarantee the auxiliary static sealing between the inner various piece of bidirectional rotation seal ring.The major metal component of combined seal ring: the sealing lip 6 of the shell 1 of metal, end cap 2, first support ring 3, second support ring 4 and PTFE material adopts turning moulding process.Rubber components: an O RunddichtringO 7, the 2nd O RunddichtringO 8, rectangular seal 9 adopt mold cure moulding process.
High voltage-resistant bi-directional rotating seal ring peculiar to vessel of the present utility model, it adopts knockdown ring structure, after seal ring uses a period of time, need to change wherein some wearing and tearing or ageing component, especially sealing lip 6, after the Renewal process of seal ring of the present utility model only needs seal ring entirety to take out, dismantle the first fastening piece 10 and sealing lip 6 can take out by the second fastening piece 11.And other metal support component are after having changed sealing lip 6, still can continue after having reconfigured according to Fig. 2 order to use.Significantly reduce unnecessary waste.The seal ring of new structure is without also no longer needing the special press tool made for metal frame b impact briquetting in original metal frame b therefore production process simultaneously, and the combination tool that original sealing lip a and metal frame b combines, thus it also greatly reduce the correlative charges of research and development of products and manufacture.
