Description
Technical field
The invention belongs to machinery manufacturing technology field, relate to a kind of reticulated rlatelet, especially relate to a kind of Compressor Valve reticulated rlatelet.
Background technique
At present, piston compressor is widely used in industrial production, and its stability run is particularly important.Air valve is one of critical component of piston compressor, usually be arranged on compresser cylinder for controlling the turnover of gas, the stuctures and properties of air valve has a great impact the air displacement of piston compressor, power consumpiton and reliability tool, is usually compared to " heart " of piston compressor by people.Now, for the air valve normally self-acting valve of piston compressor, its opening and closing decide primarily of the pressure difference of cylinder and valve intracavity gas.As everyone knows, the core component of air valve generally includes valve seat, valve block, spring and lift limiter, and wherein, valve seat has the gas channel that can be covered by valve block, be the passage with valve block one Lock air inlet (or exhaust), and bear the part of cylinder external and internal pressure difference; Valve block is used for opening or closing valve base channel, usually makes sheet, ring-type or netted; Spring promotes valve block when being and closing and falls to the element of valve seat, and suppresses valve block to clash into lift limiter when opening; Lift limiter is the element of restriction lift of valve plate.
The existing reticulated rlatelet for the netted air valve of piston compressor, because its shape is more complicated, working procedure stress is complicated, easy generation stress is concentrated, for solving the problem, buffer substrate tablet and buffer substrate tablet spring are generally set, in order to the amplitude of the striking speed and rolling motion that significantly reduce valve block and lift limiter, improve the valve block life-span.In addition, arrange buffer substrate tablet spring to also help air valve and close in time.
Application number be 201320473648.1 Chinese utility model patent disclose a kind of Valves, comprise valve plug, valve block, spring, circle, valve block pad, bolt, nut, buffer substrate tablet and guide card, from valve block, the second ring that buffer substrate tablet center is counted, radial connecting sheet is cut off, and by thin for two of valve block cut-off part semi-ring millings, make air valve operationally, valve block and buffer substrate tablet can obtain necessary elasticity, ensure the parallel motion up and down of valve block energy, valve block, the motion of buffer substrate tablet does not need guide pad just can well lead, avoid the friction between guide pad and valve block existed in ring valve.The deficiency that this technological scheme exists is: because valve block standing part and elastic part occupy certain area, therefore air valve area utilization is low; Because two semi-ring millings of valve block cut-off part are thin, easy-rupturing herein, thus cause fragment to fall into cylinder jeopardizing compressor operating.Meanwhile, valve block structure is comparatively complicated, and air valve part is many, processing difficulties, and cost is high, and valve block is fragile, causes compressor operating rate low, poor reliability, and the air valve that can not be applicable to high pressure, minor diameter.
Application number be 201310356697.1 Chinese invention patent disclose a kind of Valves for piston compressor reducing limiter thickness and then reduce air valve clearance volume, comprise valve seat, limiter and valve block, described valve seat and limiter cooperatively interact installation, described valve block is arranged between valve seat and limiter, also comprise spring sheet, described spring sheet comprises body and elastic arm; One end of described elastic arm is fixedly connected on body, and the other end is warpage shape relative to body; Described spring sheet is arranged between valve block and limiter, and the warp direction of elastic arm is towards valve block.This technological scheme is mainly based on the architecture advances to spring sheet, and the beneficial effect that can reach is exactly to save traditional spring fitting groove, thus reduces thickness, reduces the clearance of air valve.But at present, the improvement for reticulated rlatelet self structure is then relatively less.
