Zhejiang Baolun heating calorimeter sensor locking temperature measuring copper ball valve

Zhejiang Baolun valve professional production product name: forged brass temperature measuring ball valve series
Technical specification: 1
Nominal pressure: 1
6Mpa; 2
Working medium: water, oil and steam; 3
Operating temperature: -20 ℃ ≤ t≤ 120℃； 4
The test pressure shall comply with iso5208 standard; 5
Cylindrical pipe thread conforms to iso228 standard; 6
Valve material: Brass
Precautions for ball valve maintenance:
1
When the ball valve is closed, there is still pressurized fluid inside the valve body
2
Before maintenance, relieve the pipeline pressure and make the position of Da Kai at the ball valve
Before maintenance, disconnect Kai power or air supply
3
Disconnect the actuator from the bracket before maintenance
4
It is necessary to find out that the upstream and downstream pipelines of the ball valve have been relieved of pressure before disassembly and disassembly
5
During disassembly and reassembly, care must be taken to prevent damage to the sealing surface of parts, especially non-metallic parts
Special tools should be used when taking out O-rings
6
During assembly, the bolts on the flange must be tightened symmetrically, gradually and evenly
7
The cleaning agent shall be compatible with the rubber parts, plastic parts, metal parts and working medium (such as gas) in the ball valve
When the working medium is gas, metal parts can be cleaned with (gb484-89)
Clean non-metallic parts with pure Shui or alcohol
8
The individual parts disassembled can be cleaned XI by immersion
Metal parts that still have non-metallic parts that have not been decomposed can be scrubbed with clean, fine silk cloth impregnated with detergent (to avoid fiber falling off and adhering to the parts)
All grease, dirt, accumulated glue, dust, etc
adhered to the wall surface shall be removed during Xi cleaning
9
The non-metallic parts shall be taken out from the cleaning agent immediately after cleaning Xi, and shall not be soaked for a long time
10
After Xi cleaning, it is necessary to wait for the wall surface to be cleaned to volatilize (it can be wiped with silk cloth not soaked with Xi cleaning agent), but it shall not be put aside for a long time, otherwise it will rust and be polluted by dust
11
New parts shall also be cleaned before assembly
12
Lubricate with grease
The lubricating grease shall be compatible with the metal materials, rubber parts, plastic parts and working medium of the ball valve
When the working medium is gas, for example, special 221 grease can be used
Apply a thin layer of grease on the surface of the seal installation groove, on the rubber seal, and on the sealing surface and friction surface of the valve rod
13
During assembly, it is not allowed to have metal debris, fiber, grease (except for specified use), dust, other impurities, foreign matters and other pollution, adhesion or stay on the surface of parts or enter the inner cavity
