Recoil-Resistant Structure
The Structural Strength of the Reaction
When a safety valve operates, it receives a reaction force in the opposite direction to the blowing direction. In the case of a conventional type, the narrow part of the inlet flange is greatly affected (bending moment) and there is a possibility of a catastrophic breakage from that part. In contrast, the improved type has no part that receives the bending moment (meaning the flange itself can be considered a rigid body) so there is no need to worry about the Safety Valve itself being destroyed. In terms of safety, there is no better Safety Valve Structure.
When the Safety Valve is operating, the safety valves have reaction force just opposite to the blow out direction. In the case of the current model, reaction force gives the large effect to the neck of the inlet flange (bending moment). It means, easy to break down from this part. For improved as you can see there’s no effective parts if bending moment. (The flange itself is a firm substance) there’s no need to worry about the Safety Relief Valve breaking from a point of view of safety, this structure is quite safer than current use,
Even in the case of a Jacketed type, the Mounting Flange size does not need to be large.
No need to enlarge the Flange End for the installation of Jacket Type
When the fluid needs to keep warm, a jacket can is welded to the safety valve. In the case of conventional types, the jacket can interferes with the inlet piping bolts and nuts, so the flange size must be larger than the standard. This causes a lot of unnecessary work and increases the equipment costs. In contrast, the improved safety valve has embedded piping bolts, so not only can it completely cover the jacket but it also has very good Thermal Efficiency.
In case of keeping liquid hot, we weld a jacket cover to a safety valve. This jacket cover disturbs the bolts and nuts of the inlet fland end for the distribution pipe. So the flange end size will be larger than standard type. It means ordering new wooden mold, casting becomes heavy, setting flange becomes lager and so on. Many problems will be occurred. Improved flange structure solves these problems distribution bolts are stud type, perfectly covered with jackets, so the thermal effect is much improved.
Easy Maintenance
Easy Maintenance
In the case of conventional types, if we look only at the valve seat installation method, it has a screw-in structure. In this case, special jigs are required for disassembly and assembly, making on-site maintenance impossible and requiring the valve to be returned to the manufacturer. This creates other problems such as cost and time. The improved safety valve uses our proprietary bolt method for valve seat installation, which does not require special jigs and makes on-site maintenance possible.
In the case of installing a seat, the current one is a screwed type so decomposition and assembly are required for the special instrument. It is difficult to do maintenance there. To return the valve or to manufacture it its expense will be costly. Our improved one is very easy to do maintenance there because the special instrument is unnecessary. Our own bolted type is installed in the seat. Easy to decomposition and assemble
Stable, Lightweight and Compact
Stability, Compact, Lightweight
When compared to 12B/JIS20K class, the height is 70mm smaller and the weight is 60kg smaller. Furthermore, the stability when installed is greatly improved.
Comparing 12B JIS20K calss. Height 70mm shorter, weight 60Kg lighter than current model. Stability for installation is much improved.
Easy to Install
Installment becomes easy
If the piping stud bolts are attached first as shown in the diagram above, then when it is time to install the safety valve, the position can be easily determined by inserting the bolts into the holes in the flange to which they are to be attached, allowing piping to be performed quickly.
Referring to the drawing fixed the stud bolts for distribution ahead and then install the safety value, It is very easy to fix it, just these stud bolts into the hole. Also easy to fix position,
