Abstract
The utility model relates to a pipe connecting flange sealing surface structure of titanium steel or zirconium steel composite board equipment, which comprises a steel flange (1) and a titanium or zirconium liner pipe (2), wherein the liner pipe (2) is stuck in a flange hole of the flange (1), and one end of the liner pipe (2) extends out of the flange hole of the steel flange (1). The utility model is characterized in that the one of the liner pipe (2), which extends out of the flange (1), is sleeved with a titanium steel or zirconium steel composite board sealing ring (3), a steel base plate (4) of the titanium steel or zirconium steel composite board sealing ring (3) is welded with the end surface of the flange (1), and a titanium or zirconium composite layer (5) of the titanium steel or zirconium steel composite board sealing ring (3) is welded with the end surface of the liner pipe (2). In the utility model, an explosive composite board is used as a sealing ring, the steel base material of the composite board is welded with the steel end surface of the flange, the connection strength of the steel base material and the steel end surface is enhanced, simultaneously, the problem of end surface leakage of the sealing ring is solved through adding a gasket, and the corrosion of leakage on the end surface of the flange can be effectively delayed.
Description
Technical field
The utility model relates to a kind of corrosion-resistant titanium steel or zirconium clad steel plate equipment, especially corrosion-resistant reacting cylinder body pipe connecting flange structure, specifically a kind of titanium steel or the zirconium clad steel plate equipment nozzle flange gasket face (surface) structure used of chemical industry with the explosive clad plate preparation.
Background technique
At present, on the basis of satisfying device security and corrosion resisting property,, in chemical industry, be extensive use of the material of the explosive clad plate of corrosion resistant metal and steel as reactor, reactor, storage tank in order to improve the Economy of equipment.
On all kinds of reaction vessels, use pipe connecting flange in a large number, and must add titanium material or zirconium material bushing pipe in the pipe connecting flange of titanium steel or zirconium steel explosive clad plate, the end face of flange uses titanium material or zirconium material as end face sealing ring 7 usually, since titanium material or zirconium material can not be directly and the steel end face of flange be weldingly connected, adopt the method for silver brazing that titanium material or zirconium material seal ring are welded on the end face of flange during way therefore commonly used, as shown in Figure 1, because the join strength of silver brazing is not high, therefore be easy to damage in using and come off, influence the sealability of sealing surface, titanium material or zirconium material seal ring only rely on inboard bushing pipe and are weldingly connected, not only intensity is not high, and when taking place to leak, can directly produce corrosion to end face of flange, influence the working life of flange.
Summary of the invention
The purpose of this utility model is when adopting silver brazing to connect at the corrosion-resistant seal ring on titanium steel or the zirconium clad steel plate equipment pipe connecting flange, the problem that join strength is not high, design a kind of steel and steel are weldingly connected, the join strength height that adopts, the titanium steel of good seal performance or zirconium clad steel plate equipment nozzle flange gasket face (surface) structure.
The technical solution of the utility model is:
A kind of titanium steel or zirconium clad steel plate equipment nozzle flange gasket face (surface) structure, comprise steel flange 1 and titanium material or zirconium material bushing pipe 2, described bushing pipe 2 is mounted in the flange hole of flange 1, one end of bushing pipe 2 stretches out the flange hole of steel flange 1, it is characterized in that bushing pipe 2 stretches out is set with titanium steel or zirconium clad steel plate seal ring 3 on flange 1 one ends, the steel substrate 4 of titanium steel or zirconium clad steel plate seal ring 3 is weldingly connected with the end face of flange 1, and the multiple layer 5 of the titanium of described titanium steel or zirconium clad steel plate seal ring 3 or zirconium is weldingly connected with the end face of described bushing pipe 2.
Add titanium material or zirconium material gasket ring 6 between described titanium steel or zirconium clad steel plate seal ring 3 and the bushing pipe 2, described gasket ring 6 all is weldingly connected with the place, mating face of bushing pipe 2 and titanium or the multiple layer 5 of zirconium.
The beneficial effects of the utility model:
The utility model with explosive clad plate as seal ring, utilize the steel substrate of composite sheet and the steel end face of flange to be weldingly connected, both join strengths have been solved, solved the problem of the face leakage of seal ring simultaneously by the measure that increases pad, can delay the corrosion of effusion greatly end face of flange.
Description of drawings
Fig. 1 is the structural representation of existing flange facing.
Fig. 2 is a structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
As shown in Figure 2.
A kind of titanium steel or zirconium clad steel plate equipment nozzle flange gasket face (surface) structure, comprise steel flange 1 and titanium material or zirconium material bushing pipe 2, described bushing pipe 2 is mounted in the flange hole of flange 1, one end of bushing pipe 2 stretches out the flange hole of steel flange 1, bushing pipe 2 stretches out and is set with titanium steel or zirconium clad steel plate seal ring 3 on flange 1 one ends, the steel substrate 4 of titanium steel or zirconium clad steel plate seal ring 3 is weldingly connected with the end face of flange 1, as Fig. 2, because both are the steel welding, therefore weld strength is very high, overcome the strength problem that employing silver brazing shown in Figure 1 is brought, the multiple layer 5 of the titanium of described titanium steel or zirconium clad steel plate seal ring 3 or zirconium is weldingly connected with the end face of described bushing pipe 2.In addition, in order to prevent that effusion from directly producing corrosion to end face of flange, delay the corrosion of effusion to end face of flange, but during concrete enforcement also the structural feature at reference composite plate junction plane place between titanium steel or zirconium clad steel plate seal ring 3 and bushing pipe 2, install titanium material or zirconium material gasket ring 6 additional, described gasket ring 6 is located all to be weldingly connected with the mating face of bushing pipe 2 and titanium or the multiple layer 5 of zirconium.
As seen from Figure 2, if bushing pipe 2 leaks with the weld of seal ring 3, leakage then at first produces corrosion to the steel substrate 4 of seal ring, can directly not produce corrosion to flange, this just can win the necessary time for maintenance, simultaneously, because the junction plane place of seal ring and flange is the welding of same material, therefore join strength is guaranteed, has fundamentally overcome the existing defective of silver brazing shown in Figure 1.
The utility model does not relate to the part prior art that maybe can adopt all same as the prior art to be realized.
