Since it can't be screwed, you should knock it a few times first (it doesn't hurt to knock more), then apply some engine oil, and then knock, don't be in a hurry to screw it after applying the oil, wait for a period of time and then twist it, and then it will be troublesome, and you can connect the faucet and the connected section of the water pipe together.

My understanding:

1.First of all, the shut-off valve +J41H-16C DN20 is the same.

But there is one more A105, first of all, let's understand A105

A105 is the American ASTM standard number, and A stands for ordinary carbon steel. Standard name: carbon steel forgings for pipeline components.

Because this standard only stipulates one carbon steel forging, A105 is also a forging carbon steel grade. A105 is also a material code, which belongs to special steel and is a kind of cold-forged steel. A105 is a mild steel forging, similar to 20 steel.

There are two standards, one is the American standard "ASTM A105 A105M carbon steel forgings for pipe components", and the other is the Chinese standard "GB T12228-2006 General Valve - Technical Conditions for Carbon Steel Forgings".

Material Grade: A105 Standard: ASTM A105 Carbon Steel Forgings for Pipe ComponentsCountry/Region:

After reading the introduction of A105, it is not difficult to see that the former has special requirements for the material of the valve body.

The needle valve has beautiful appearance, good sealing performance, high pressure resistance, and easy disassembly, assembly and maintenance.

J24W Needle Valve Installation Precautions.

1. The installation position, height, and inlet and outlet directions must meet the design requirements, and it should be noted that the direction of the medium flow should be consistent with the direction of the arrow marked by the valve body, and the connection should be firm and tight.

2. The visual inspection must be carried out before the valve is installed, and the nameplate of the valve should comply with the provisions of the current national standard "General Valve Mark" GB 12220. For valves with working pressure greater than MPA and shut-off on the main pipe, strength and tightness performance tests should be carried out before installation, and they should be used only after they are qualified. During the strength test, the test pressure is times of the nominal pressure, the duration is not less than 5min, and the valve housing and packing should be qualified without leakage.

During the tightness test, the test pressure is multiple of the nominal pressure; The duration of the test meets the requirements of GB 50243.

Shanghai, Yiling valve. Let's ask the landlord himself.
