Embodiment Construction

[0017] The present invention will be described in further detail below.

[0018] A valve cleaning method, comprising the following steps:

[0019] Step 1: Prior to assembly, each internal valve part needs to be thoroughly cleaned in a TCE tank and then dried in a hot air or nitrogen drying area. The inside of the valve body needs to be wiped clean with a cloth;

[0020] Step 2: Wear talc-free polyethylene gloves when assembling the valve, and perform it in a dust-free workshop of grade 100,000 or an equivalent particle-free surface; use clean and grease-free tools during assembly; all gasket surfaces must be Scrub with methanol;

[0021] Step 3: Nitrogen leak detection for the assembled valve; paint, and visually check whether the inside of the valve is clean after painting.

[0022] Step 4: Packaging

[0023] a) Before putting the valve cover on the valve, wipe the flange surface with methanol again to ensure that these surfaces are clean;

[0024] b) Each assembled term...

Abstract

The invention discloses a valve cleaning method. Before assembly, each inside valve component needs to be thoroughly cleaned in a TCB tank, than each inside valve component is dried in a hot air or nitrogen drying area; the inside of a valve body needs to be wiped clean by wiping cloth; when a valve is assembled, polyethylene gloves without talcum powder need to be worn; in assembly, a clean grease-free tool is used; in assembly, surfaces of all spacers are scrubbed by methanol; nitrogen leakage detecting is conducted on an assembled valve; painting is conducted, and whether the inside of the valve is clean or not is visually inspected after the painting; packaging is conducted.

Description

technical field [0001] The invention relates to a cleaning method, in particular to a valve cleaning method. Background technique [0002] At present, valves are used in the pipelines of various chemical plants. During the long-term use of the valves, due to the presence of various chemical impurities in the pipelines in the solution, dirt is easily generated inside the valves, and these dirts greatly affect the use of the valves. Therefore, how to better clean the valve has very practical significance. Contents of the invention [0003] Aiming at the above problems, the present invention provides a very effective and fast valve cleaning method. [0004] In order to solve the above problems the present invention provides a valve cleaning method, comprising the following steps: [0005] Step 1: Prior to assembly, each internal valve part needs to be thoroughly cleaned in a TCE tank and then dried in a hot air or nitrogen drying area. The inside of the valve body needs to...
