Carry out the pressure test and leak test, and the installation can only be carried out after passing the test. The installation method is flange connection. Pay attention to the following points when installing various valves:

(1) Butterfly valve installation

a) When installing the butterfly valve, pay attention to the direction, the direction of medium flow is consistent with the direction of the arrow shown on the valve body.

b) When installing the butterfly valve, the valve plate stops at the closed but not tightly closed position or according to the requirements of the supplier, the hand wheel is easy to operate, and the opening position is determined according to the rotation angle of the valve plate.

c) The weight of the butterfly valve cannot act on the pipeline.

d) The gaskets used in disc valve flanges are of qualified quality and do not add double gaskets or partial gaskets.

e) The welding of the flange meets the relevant welding requirements.

f) After the installed disc valve is installed, set a solid foundation according to the design requirements.

(2) Check valve installation

Check valves should be products from regular manufacturers with certificates of conformity. After the equipment enters the site, the impurities in the valve body should be removed, and the installation can only be carried out after passing the water seal test.

a) For the installation of water pumps, select products from regular manufacturers with certificates of conformity.

b) Installation in the equipment room: automatic cleaning filters, ultraviolet sterilizers and other equipment and materials are selected from regular manufacturers, with certificates of conformity, and constructed and assembled according to the requirements of the manufacturer.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not intended to limit it; although the application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: It is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the various embodiments of the application. scope.
