Abstract
The utility model discloses a kind of safety valve pipe joint stiffening device, comprise safety valve pipe joint, chuck mode safety valve fixing device, it is characterized in that safety valve pipe joint is provided with chuck mode safety valve fixing device.The moment that it produces while making safety valve pipe joint can bear safety valve steam discharge, manufacture mounting process is simple and convenient, compact structure, the torque tubes joint having produced because of discharge counter-force while having overcome safety valve steam discharge fractures and has to increase in setting safety valves support to offset moment, has also avoided using clumsy thick walled tube joint to cause the problems of welded quality such as not weld penetration, slag inclusion, pore.
Description
Technical field
The utility model relates to a kind of safety valve pipe joint stiffening device, relates to particularly boiler shell, header and pressurized container pipe joint.
Background technique
Boiler shell, header and pressurized container be the rising along with pressure rating with safety valve pipe joint, the requirement of strength of pipe joint is just higher, in order to increase the counter-force producing when pipe joint bears safety valve exhaust, in the time manufacturing and designing, often adopt the mode of thickening safety valve pipe joint wall thickness and installing safety valve support additional.Although this measure also can reach the object of safe handling safety valve, but manufacturing inspection complex process, and easily there are quality problems in thick walled tube joint welding, as welding process built-up welding causes repeatedly welding Interlaminar Crack, pore, slag inclusion, postwelding has internal stress residue affects the working life of pipe joint in member, it is attractive in appearance etc. that simultaneously postwelding has the macroscopic deformation impact of component partial, the safety valve support increasing separately in addition need to take very large space, manufacturing and installing also needs to consume a large amount of man power and materials, economical not.The scheme of easy economy and use a kind of safety valve pipe joint stiffening device.
Summary of the invention
The purpose of this utility model is to provide a kind of safety valve pipe joint stiffening device, it is in a chuck mode safety valve fixing device of the outside increase of common pipe joint, this safety valve pipe joint stiffening device, the counter-force that it produces can bear preferably safety valve steam discharge time; While this kind of safety valve pipe joint stiffening device also adapts to have very much the pressurized container connecting tube of horizontal thrust.
The utility model is achieved like this.It comprises pressure-vessel, safety valve pipe joint, chuck mode safety valve fixing device, safety valve, the top of safety valve pipe joint is provided with safety valve, the bottom of safety valve pipe joint connects pressure-vessel, the surrounding that it is characterized in that safety valve pipe joint is furnished with chuck mode safety valve fixing device, and chuck mode safety valve fixing device is connected on pressure-vessel.
Between described chuck mode safety valve fixing device and pressure-vessel, adopt traditional weld seam Placement, between chuck mode safety valve fixing device and safety valve pipe joint, do not weld.
Between described safety valve pipe joint and pressure-vessel, adopt weld seam to be connected.
Described pressure-vessel is boiler shell or header or pressurized container.
Technique effect of the present utility model is: substitute heavy wall safety valve pipe joint and safety valve support by safety valve pipe joint stiffening device, the moment that it produces while making safety valve pipe joint can bear safety valve steam discharge, manufacture mounting process is simple and convenient, compact structure, the torque tubes joint having produced because of discharge counter-force while having overcome safety valve steam discharge fractures and has to increase in setting safety valves support to offset moment, also avoided using clumsy thick walled tube joint to cause not weld penetration, slag inclusion, the problems of welded quality such as pore, , save the shared space of safety valve support and manufactured and designed installation cost, save the steel consumption of safety valve pipe joint, beautify the profile of safety valve pipe joint, increase the competitiveness of product in market, also strengthened the versatility of safety valve pipe joint and other pipe joints simultaneously.
