Ramsbottom Safety Valve - Components & Assembly · 模型 50597
It is a boiler mounting and a safety device which protects the boiler against building-up of excess pressure. The spring used in the safety valve is set to act when the steam pressure exceeds the set value and allows the steam to escape. Thus, only the permissible value of steam pressure is allowed inside the boiler. It consists of housing with two valve chests. The valve seats are screwed into the housing and valves are located in the valve seats. The eye bolt is fastened to the bridge of the housing, by means of washer and both the nuts. Pivot is pinned to the lever and it is placed over the valves and held in position by safety links and spring. The safety links are fixed at one end to the lever and the other end to the eye bolt by pins and split pins. The required rigidity is provided to this assembly by fixing the spring between the eye bolt and the lever (holes are provided in the lever and eye bolt for this purpose). When the set value of the pressure exceeds in the boiler, the lever moves and allows the valves to get lifted from the seats concerned. The movement of the lever is permitted due to the slot provided centrally in it and returns to the original position due to spring action. In Ramsbottom safety valve, spring load is used to lift the valves, when excess pressure of steam is built-up. It is mostly used in a locomotive boiler. Whenever steam pressure exceeds the designed value of the spring force, the excess pressure lifts the valves, allowing steam to escape till the pressure decreases to the permissible value.* - The model has been created on Siemens NX. - The constraints have been created by aligning CSYS to CSYS as interfaces. - Also, the screw threads have been created by using WAVE Geometry Linker. - All the components are in STL Format for 3D Printing Process. *Narayana K.L., Machine Drawing 3rd Edition
