Abstract
The present invention relates to safety valve for industrial steam boiler. On the boiler body, one hole of 12 mm diameter is formed, one middle part of the same material with the boiler body and 8 mm diameter is set, and the 2 mm wide gap around the middle part is filled with copper material through welding. The copper material has relatively lower melting point and in case of overhigh temperature, the welding gap material will melt and fall off to release pressure from the boiler. The easy to melt valve is well combined with the boiler body and is compatible to the boiler body.
Description
Technical field
The present invention relates to safety valve for industrial steam boiler.
Background technology
The Industrial Boiler Relief Valve of prior art all be with the fusible material riveting on boiler body, it and boiler body are always incoherent on the gold picture, also do not involve mutually when cold and hot harmomegathus.
Summary of the invention
In order to address the above problem, the purpose of this invention is to provide a kind of steam boiler safety valve that combines with furnace binding on as level at gold.
In order to achieve the above object, steam boiler safety valve provided by the invention is the hole of opening one 12 mm dia on body of heater, and identical with the body of heater material in one of the central placement in hole, diameter is 8 millimeters a intermediate, the border of intermediate is 2 millimeters a seam, and this seam is full with the copper material weldering.
Just combined as level upper furnace body structure and meltable valve at gold like this.
Description of drawings
Fig. 1 is the cutaway view of steam boiler safety valve.
The specific embodiment
As shown in Figure 1, on body of heater 1, open the hole of one 12 mm dia, one of central placement in the hole is identical with the body of heater material, diameter is 8 millimeters a intermediate 3, and the border of intermediate is 2 millimeters a seam 2, and this seam is full with the copper material weldering, when stove body temperature surpasses the fusing point of weld seam fusible material, the fusing of weld seam fusible material, weld seam fusible material and intermediate all come off from body of heater, and play the effect of pressure release.Like this gold as level on, furnace binding and meltable valve have just combined, and have produced good coherence between body of heater and the meltable valve, have just produced mutually to involve when cold and hot harmomegathus, can be when cold and hot harmomegathus the loosening phenomenon of recurring structure.
