Pneumatic flange pneumatic valve, pneumatic pneumatic pneumatic valve accessories such as pneumatic valve is often easier than pneumatic valve itself to damage, such as flange gaskets, so how to replace the damaged flange gasket?
change the flange gasket needs to follow the following four basic principles, ready to materials and tools, pay attention to the operation steps, to achieve two technical requirements and five points.
( 1) Preparations for
(1) material: butter, cotton yarn, liquid leakage and sealing gasket.
2) tools: wrench, screw whorls.
( 2) Operation steps
(1) remove flange bolts, remove the pneumatic valves or move to let the cat out of the end section. Remove old gasket seal face.
2. Select the appropriate gaskets, a layer of butter evenly on both sides.
(3) the sealing gasket cushion between two flanges, seal face alignment between the flange and bolt hole in the middle, into the bolt, screw nut, even several times diagonal tighten nut. Bolt nut length 2 - 3 it is advisable to pitch. Flange gasket after the installation, should do after work pressure test for qualified without leakage.
( 3) Technical requirements for
(1) should be careful operation, to prevent damage to the flange.
2. When completed, tools for cleaning and maintenance.
( 4) Gasket installation five points
1) choose right: the form of flange, bolts, gaskets, the material, the size should be according to the operating conditions and equipped with the appropriate form of the flange surface structure.
(2) check: finely before installation should carefully check the quality of the flange, bolts, nuts, gaskets, should be no burr, uneven, crack defects, etc. Carefully check the flange, pipe installation, should be unbiased, wrong, wrong hole mouth mouth phenomenon.
3. Have the net: flange sealing surface must be clean, bolt, gaskets shall not be with the impurities, grease, etc.
(4) pack is: in gasket should be one of pipe or tube.
(5) on the well: installation bolt, nut application force uniform, points repeatedly symmetry on tight.
mastering above 2 technology and five points, believe you how to replace the pneumatic flange pneumatic valve, pneumatic flange pneumatic valve flange gasket will have a new understanding, later encountered a similar problem, also it is easier to solve.
