Description
Technical field
The present invention relates to butterfly valve Assembling Production technical field, particularly relate to a kind of butterfly valve assembling line.
Background technology
Butterfly valve has that structure is simple, volume is little, lightweight, material consumption is economized, installation dimension is little, the features such as switch is rapid, driving moment is little, for blocking, connecting, regulate the medium in pipeline, simple to operate, there is good fluid handling properties, be widely used in the fields such as oil, coal gas, chemical industry, water treatment at present.Butterfly valve mainly comprises to be with the annular valve of upper and lower valve neck, the round ring seat be inlaid on valve interior wall, circular valve plate and to insert the upper lower valve shaft (twin shaft butterfly valve) on valve plate in lower shaft hole via the axis hole at upper and lower valve neck axis hole, valve seat two ends respectively, or inserts the axis (axis butterfly valve) in lower valve neck axis hole via the axis hole at upper valve neck axis hole, valve seat two ends, valve plate axis hole.During use, its disc valve plate perpendicular to Pipe installing, and centered by valve shaft axle reciprocating rotary between 0 ° ~ 90 °, realize full cut-off standard-sized sheet.
In butterfly valve manufacture process, the part of processing mainly comprises valve body, valve seat, valve plate, valve shaft, axle sleeve, spacing gland, scale arresting disc and drive unit, butterfly valve assembling is mainly included on valve body installs axle sleeve, valve seat, valve plate, valve shaft, then valve plate is closed leveling and carry out pressurization test, axis butterfly valve is also divided into axis to have pin butterfly valve and axis without pin butterfly valve, has pin butterfly valve for axis, after the pin installing fixing valve shaft additional, also secondary seal performance test will be carried out.In current industry, the assembling of the assembling of butterfly valve especially small dimension butterfly valve is still based on manual operations, because the valve seat of butterfly valve and valve body are interference fits, valve plate and valve seat are interference fit, the axis hole of valve shaft and valve seat is interference fit, therefore, certain external force must be applied during each structural member assembling above just can complete, generally when mounted, also assist mallet valve seat, valve plate, valve shaft to be loaded by manpower.Because manual force is lack of standardization, the valve body after installation, valve seat, valve plate axis hole axiality is not only made to be difficult to ensure, and owing to impacting the damage easily causing structural member, affect product quality, and labour intensity is high, labor intensive, man-hour, noise is large, has a strong impact on production environment.In recent years also develop valve seat, shaft installation machine, but the assembling of valve seat, valve shaft is still for separate operaton carries out, in addition, the round transport of assembly parts in each operation, the replacing not only elapsed time but also waste of manpower of frock clamp, reduce production efficiency, improves production cost.
In addition, after mounting, valve plate is in inclination opening state to butterfly valve, before leakage test, by operating personnel, valve plate must be turned to horizontal closed position from obliquity.Current valve plate horizontal closed operation adopts hand-operated valve plate closing pressue device, this valve plate closed pressurizing device adopts manual gear, tooth bar machine driving pressue device, by rotating handwheel, the cylindrical rack engaged with it by gear driven is descending, driving top-pressure part to press down makes valve plate reach closure state, afterwards, then by spring top-pressure part is resetted.Adopt rack and pinion engagement to drive and spring reset frame for movement, easily produce fault, especially need manually to operate in operation, labor intensity of operating staff is large, and waste time and energy, production efficiency is low.
Also need carry out the test of pressure-resistant seal performance according to the pressure of applying working condition and standard-required to the butterfly valve after assembling, determine butterfly valve internal cavity airtight performance.Existing butterfly valve seal performance aircraft, has that to adopt take water as the structure of sealing medium single test valve and single test side cavity, and this structural test efficiency is low, also employing is had to be sealing medium with gas, once test two or more valve simultaneously, once test the structure of both sides cavity simultaneously, apply this structure, butterfly valve and the air leakage pipe of being drawn by its cavity are immersed in water, in water, whether produce bubble by observation air leakage pipe to determine whether to leak, but the shortcoming of this structure is the gas leakage pipe range because drawing, leak gas not obvious, easy generation erroneous judgement, and adopt leaching butterfly valve sink structure, cause complex structure, waste water source, affect environment, in addition, the placement of tested butterfly valve on pressure testing plate is by range estimation location, inaccurate, normally carrying out of impact operation, especially existing test method is still Non-follow control, inefficiency.
In sum, how for the problems referred to above, the equipment of closed, experiments of sealing performance is flattened to existing butterfly valve assembling, valve plate and operation improves, and form continuous working production line, realize high-effect high-quality assembling, improve work situation and become industry concerned issue.
