Z41 doesn't need to be talked about.

The W and T here refer to the sealing surface or lining material, and W refers to the sealing surface as the material of the valve itself.

t The sealing surface is copper alloy.

z represents the type class code of the gate valve, which is the first letter of the gate valve pinyin. The belonging of the gate valve adopts the manual drive mode, 1 indicates that the connection form of the gate valve is an internal threaded connection, 5 represents the structural form of the gate valve is a single gate plate, T represents that the lining material of the gate valve is copper alloy, 16 represents the nominal pressure of the gate valve, and C represents the valve body material of the gate valve is carbon steel.

The gate valve is a gate plate with opening and closing parts, the direction of movement of the gate plate is perpendicular to the direction of the fluid, and the gate valve can only be fully opened and closed, and cannot be adjusted and throttled. The gate valve is sealed by the contact between the valve seat and the ram, and usually the sealing surface will be surfacing with metal materials to increase wear resistance, such as surfacing Sila 1Cr13, STL6, stainless steel, etc. The gate has a rigid gate and an elastic gate, and according to the different gates, the gate valves are divided into rigid gate valves and elastic gate valves.

Hello dear, DZ41H-16C is a self-locking isolation gate valve. Its main features are: Type:

Double door partition Dan off the valve. Material: ductile iron shell, ultra-low temperature carbon steel valve.

Working pressure: PN16. Operating Temperature:

20°c~180°c。Connection Type: Threaded, Welded.

Control mode: manual control. Applicable Scenarios:

Pressurized equipment, water treatment systems, etc. Isolation effect: Prevent the fluid at both ends from leaking from each other.

Model Marking Description: dz: stands for Dezhi brand 41:

The representative diameter is 41mmh: on behalf of PN16 gas collector pipe fitting 16: on behalf of PN16 pressure level C:

In general, DZ41H-16C is a gas collection self-locking isolation gate valve, which is mainly used in water treatment systems and pressurized valves, and is used for the isolation and shut-off of fluids on the upper and lower sides of the valve. The key configuration of the punch shirt is: ductile iron shell, ultra-low temperature steel valve thread or welded connection, manual operation, I am glad to answer for you, I hope to help you.

Summary. Possible causes: debris or poor meshing between the stem and the stem nut, separation of the stem and disc, corrosion of the stem and stem nut, excessive force on the disc and pressure of the packing material.

2) Treatment method: Lubricate the valve stem and valve stem nut frequently and remove debris; The valve stem is separated from the valve disc and should be disassembled and overhauled; When the disc is stressed too much, the valve is opened when the pressure is reduced.

What does the gate valve Z561Y model mean.

For you to inquire: z== gate valve 5== drive Dan opening mode: bevel gear 6== connection form: welded type 1== structural form: rigid Sun Yi single ram y== sealing surface material: hard clamping Kai Sui gold.

Now the valve can't be opened, and the handwheel opens easily, but the ram does not move.

Possible causes of original volt regression: debris or poor meshing between the stem and the stem nut, separation of the stem and disc, corrosion of the stem and stem nut, excessive force of the disc and packing pressure. (2) Solution:

Lubricate the stem and stem nut frequently and remove debris; The valve stem is separated from the valve disc and should be disassembled and overhauled; When the valve disc is stressed too much, the valve will be opened after the pressure is lowered.

Summary. It should be that the valve plate is bitten, the reason may be that a foreign object has been trapped between the valve plate and the valve housing, or it has not been rusted for a long time.

If the stem is a screw, you can try turning the handwheel with an extension rod. If you really can't do it, you have to remove the valve and check it.

What does the gate valve Z561Y model mean.

Gate valve Z561Y model, 5 is bevel gear transmission according to the provisions of the "JB T 308-2004 valve model preparation method of the world": Z== gate valve 5== drive mode: bevel gear 6== connection form:

Pick-up welded type 1== Structural form: Gangchun reversible single ram y== Sealing surface material: cemented carbide.

Thank you for your understanding. Now the valve can't be opened, the handwheel can easily rotate, but the ram and lead screw don't move!

What is the reason, please.

You know. It should be that the valve plate is bitten to death, and the original Huai waiter may have a foreign object sandwiched between the valve plate and Lu Ming's valve shell, or it has not been rusted for a long time. If the stem is a screw, you can try it with an extension rod to turn the handwheel.

If you really can't do it, you have to remove the valve and check it.
