Abstract
The invention discloses a lip-shaped welding ring on a gasification furnace. The lip-shaped welding ring comprises a pair of butted lip-shaped welding ring bodies, wherein two butted pressure testing bosses are formed outside grooves on the outer circumferences of the lip-shaped welding ring bodies. The lip-shaped welding ring has the advantages that the pressure testing bosses are formed outside the grooves on the outer circumferences of the lip-shaped welding ring bodies, the gasification furnace can be subjected to pressure testing only by welding the pressure testing bosses on the two lip-shaped welding ring bodies, and the pressure testing bosses are directly removed after the gasification furnace are subjected to pressure testing, so that the manufacturing cost is greatly reduced, and the manufacturing efficiency is greatly improved.
Description
Technical field
The present invention relates to for the lip weld-ring on the vapourizing furnace.
Background technology
Be provided with a pair of sealing usefulness, mutual involutory lip weld-ring 1 on the vapourizing furnace, because therefore its shape approximation Ω is also referred to as the Ω weld-ring, can be referring to Fig. 1.Vapourizing furnace is when pressure testing, need first groove 2 places of two lip weld-rings 1 to be welded, then carry out the vapourizing furnace pressure testing, after pressure testing is finished the weld seam between two lip weld-rings 1 is excluded, two lip weld-rings 1 are separated from each other, carry out again lining construction, the internal installation of vapourizing furnace.Yet two lip weld-rings 1 are separately needed use carbon arc air gouging, and the shape of excluding groove 2 original behind the weld seam just can't guarantee, needs the repair welding reconditioning, wastes a large amount of man-hours, and cost of manufacture is high, and production efficiency is low.
Summary of the invention
The technical issues that need to address of the present invention are: provide a kind of simple in structure, what can greatly reduce production costs and increase work efficiency be used for lip weld-ring on the vapourizing furnace.
For addressing the above problem, the technical solution used in the present invention is: the lip weld-ring on the vapourizing furnace, comprise a pair of mutually involutory lip weld-ring body, the groove at each lip weld-ring body excircle place is outside equipped with the pressure testing boss, and the pressure testing boss on two lip weld-rings is also mutually involutory.
Beneficial effect of the present invention: owing to outside the groove at lip weld-ring body excircle place, being provided with the pressure testing boss, when vapourizing furnace needs pressure testing, only need the pressure testing boss on two lip weld-ring bodies is welded, after finishing, pressure testing directly the pressure testing boss is excluded, so not only greatly reduce cost of manufacture, also greatly improved production efficiency.
Description of drawings
Fig. 1 is the structural representation of the lip weld-ring described in the background technology.
Fig. 2 is the structural representation for the lip weld-ring on the vapourizing furnace of the present invention.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing and optimum embodiment.
As shown in Figure 2, be used for the lip weld-ring on the vapourizing furnace, comprise a pair of mutually involutory lip weld-ring body 1, the pressure testing boss 2 that the groove at each lip weld-ring body 1 excircle place is outside equipped with on 2, two lip weld-rings of pressure testing boss body 1 is also mutually involutory.
Using method is as follows: during the vapourizing furnace pressure testing that pressure testing boss 2 welding on two lip weld-ring bodies 1 are involutory, then carry out pressure testing.After pressure testing is complete, pressure testing boss 2 on the two lip weld-ring bodies 1 is directly excluded, and the mill of the groove Lve Zuo Xiu on two lip weld-ring body 1 excircles is got final product, so not only guaranteed original groove shape, greatly reduce cost of manufacture, also greatly improved production efficiency.
Claims (1)
1. be used for the lip weld-ring on the vapourizing furnace, comprise a pair of mutually involutory lip weld-ring body, it is characterized in that: the groove at each lip weld-ring body excircle place is outside equipped with the pressure testing boss, and the pressure testing boss on two lip weld-ring bodies is also mutually involutory.
