Abstract
A leakproof double-layered protection structure for the adapter sealing ring of zirconium steel compound plate equipment comprises a steel adapter (1), a zirconium liner tube (2) and a zirconium sealing ring (3). The liner tube (2) is positioned in the adapter (1), and the sealing ring (3) is welded with the adapter (1) and the end surface of the liner tube (2) respectively. The protection structure is characterized in that a zirconium cover plate (4) is welded on the inner ring surfaces of the sealing ring (3) and of the liner tube (2); one end of the cover plate (4) is welded with the inner ring surface of the sealing ring (3), and the other end thereof is welded with the inner end surface of the liner tube (2); and a radial leak detection hole (5) is formed on the sealing ring (3) and is directly communicated with the bonding surface of the cover plate (4) and the sealing ring (3). The protection structure can prolong the service life of the adapter and can play an important role on stable production.
Description
Technical field
The utility model relates to a kind of Clad Steel Plate chemical industry operative installations, the adapter seal ring anti-leak protection structure of using always in especially a kind of Clad Steel Plate chemical industry equipment, and specifically a kind of zirconium clad steel plate equipment is taken over seal ring anti-leak double shielding structure.
Background technique
At present, in order to improve the corrosion resisting property of chemical industry equipment, reduce the cost of raw material, in chemical industry, the general higher metal composite panel manufacturing apparatus housing of usability price ratio, make the requirement of strength that parent metal guarantees equipment by the lower carbon steel of price, guarantee the corrosion resistance requirement of equipment by the specialty metal layer of writing in reply.
It is a kind of common inputoutput unit of linking to each other with apparatus casing of being used for that equipment is taken over, and its material structure is similar to apparatus casing, seals by welding between the seal ring of pipe connecting flange end face and the bushing pipe.Because soldering point is the most perishable and place damaged in the pressure vessels for the chemical industry, in case the joint welding between seal ring and the bushing pipe leaks, corrosive liquid will be taken over body to carbon steel and carry out corrosion and damage, influence the safe handling and the life-span of equipment.And, this still there is not good solution because parking maintenance causes heavy economic losses.
Summary of the invention
The purpose of this utility model is to take over easily the be damaged characteristics of leakage of seal ring and liner adapter weld seam at zirconium clad steel plate equipment; design a kind of joint working life of effectively prolonging; can not only forecast in advance leaking; and in case occur leaking; the body that corrosive liquid also can not taken over carbon steel immediately carries out corrosion and damage, thereby causes the composite board equipment of parking maintenance to take over seal ring anti-leak double shielding structure.
The technical solution of the utility model is:
A kind of zirconium clad steel plate equipment is taken over seal ring anti-leak double shielding structure, comprise steel adapter 1, zirconium bushing pipe 2 and zirconium seal ring 3, described bushing pipe 2 is arranged in takes over 1, seal ring 3 respectively with take over 1 and the end face of bushing pipe 2 be weldingly connected, it is characterized in that being welded with zirconium cover plate 4 on the inner ring surface of seal ring 3 and bushing pipe 2, one end of cover plate 4 and the inner ring surface of seal ring 3 are weldingly connected, and the interior edge face of the other end and bushing pipe 2 is weldingly connected; On described seal ring 3, also offer radially leak hunting aperture 5, these leak hunting aperture 5 straight-through cover plates 4 and seal ring 3 junction planes.
Be provided with zirconium backing plate 6 in adapter 1 and end, bushing pipe 2 mating face.
The beneficial effects of the utility model:
The utility model is taken over easily the be damaged characteristics of leakage of seal ring and liner adapter weld seam at zirconium clad steel plate equipment; adopt the double shielding structure; can prolong the connection lifetime between seal ring and the bushing pipe greatly; if cover plate corrosion leakage; can predict in advance by leak hunting aperture; for next step takes measures to gain time, and can not influence the normal operation of equipment.
The utility model is simple in structure, easy construction.
Description of drawings
Fig. 1 is the structural representation that adapter seal ring of the present utility model is connected with bushing pipe.
Fig. 2 is the local enlarged diagram of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 1, 2.
A kind of zirconium clad steel plate equipment is taken over seal ring anti-leak double shielding structure; comprise steel adapter 1, zirconium bushing pipe 2 and zirconium seal ring 3; described zirconium bushing pipe 2 is arranged in steel and takes over 1; zirconium seal ring 3 respectively with take over 1 and the end face of bushing pipe 2 be weldingly connected; it is characterized in that being welded with zirconium cover plate 4 on the inner ring surface of seal ring 3 and bushing pipe 2; the inner ring surface of the upper end of cover plate 4 and seal ring 3 is weldingly connected, and the interior edge face of lower end and bushing pipe 2 is weldingly connected.For the ease of weld job, prevent distortion, be provided with backing plate 6 in adapter 1 and end, bushing pipe 2 mating face, as shown in Figure 2.On described seal ring 3, also offer radially leak hunting aperture 5, these leak hunting aperture 5 straight-through cover plates 4 and seal ring 3 junction planes.In addition, when specifically implementing, for the ease of the corrosion leakage situation of observation bushing pipe, thereby whether judgment device needs parking maintenance immediately, also corresponding leak hunting aperture can be set on the pipe shaft of adapter 1, as Fig. 1
From Fig. 1,2, can find out; because the soldering point of bushing pipe and seal ring is covered by cover plate; therefore; even the corrosion due to welding seepage occurs; the solder joint that so at first occurs destroying also is the solder joint between cover plate and seal ring or the bushing pipe; at this moment; corrosive liquid can infiltrate along the junction plane of cover plate and bushing pipe or cover plate and seal ring in the leak hunting aperture 5; operator can in time find; owing to also have one deck protection; this moment, dispense with parking was taken measures after can waiting this manufacturing process to finish again, this shows that the utility model is significant for the steady production flow process.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
Claims (2)
