Abstract
The utility model discloses a combined porous plate, which comprises an outer flange and an inner opening ring. The flange and the opening ring are provided with mutually buckled steps. The combined porous plate is characterized in that the two end faces of the flange and the opening ring are fixedly coupled through weld seams. The utility model is firmly connected, has long service life, and is suitable for high-temperature and high-pressure conditions.
Description
Technical field
The utility model relates to a kind of built-up type orifice plate.
Background technology
At present in the technological process of production of the many alumina producers of China, the flow passage components that use in partial container is irritated: orifice plate, bear high temperature about 270 ℃, pressure and receive washing away of solution at the 4Mpa aluminic acid; Existing orifice plate, as shown in Figure 1, comprise the ring flange 4 in the outside, inboard choma 5, ring flange 4 and choma 5 are provided with the step of mutual fastening, ring flange 4 and choma 5 are that two kinds of unlike materials and inlay by shrink-fit are connected, because two kinds of unlike materials are easy to generate stress deformation under high temperature, highly compressed situation, cause ring flange 4 and choma 5 to come off, and influence the work-ing life of product.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of built-up type orifice plate is provided, it have be connected firmly, the advantage of long service life, can be applicable to high temperature, high-pressure working condition.
For achieving the above object, a kind of built-up type orifice plate of the present utility model comprises the ring flange in the outside, inboard choma, and ring flange and choma are provided with the step of mutual fastening, it is characterized in that the both ends of the surface of ring flange and choma all connect firmly by weld seam.
The utility model since ring flange and choma connect firmly by weld seam, have be connected firmly, the advantage of long service life, can be applicable to high temperature, high-pressure working condition.
Description of drawings
Fig. 1 is the front view of existing orifice plate.
Fig. 2 is the front view of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As shown in Figure 2, a kind of built-up type orifice plate of the present utility model comprises the ring flange 1 in the outside, inboard choma 2, and ring flange 1 and choma 2 are provided with the step of mutual fastening, and the both ends of the surface of ring flange 1 and choma 2 all connect firmly by weld seam 3.
The utility model since ring flange 1 and choma 2 connect firmly by weld seam 3, have be connected firmly, the advantage of long service life, can be applicable to high temperature, high-pressure working condition.
