The counterclockwise rotation of the valve is on.

In general, counterclockwise is on, and clockwise is off.

Generally, it is closed clockwise and turned counterclockwise.

The opening and closing directions of all valves are: looking down at the valve handwheel, clockwise for closing, counterclockwise for open.

The heating valve is open in which direction.

In general, all kinds of valves areClockwiseYes off, counterclockwise is on, there will be special marks in special cases. The switch is generally in the shape of a handle, the handle and the valve are fully open in the same direction, if there is a hand wheel, rotate to the direction of the right thumb is open, and vice versa. The handle is open along the pipe, and the handle is closed at 90 degrees from the pipe.

The manual valve is the most widely used valve, and its handwheel or handle is designed according to ordinary manpower, taking into account the strength of the sealing surface and the necessary closing force. Therefore, long levers or long boards cannot be used.

Hands to move. Some people are accustomed to using wrenches, and should pay strict attention not to use too much force, otherwise it is easy to damage the sealing surface.

Precautions when operating the valve.

1. For the manual door of each water drain in the thermal system, it should be tightened again half an hour after the operation is completed to eliminate thermal expansion and contraction.

caused by the valve clearance.

2. For the setting there is.

The operation sequence of the valve of the thermal pipeline of the primary and secondary doors is as follows: when opening, the door should be opened once and then the secondary door; When closing, the door should be closed twice and then again.

3. For the operation of the gate valve, it can only be fully closed or fully opened, and the half-open and half-closed state is not allowed to reduce the blowing damage to the valve.

The valve is generally closed clockwise and opened counterclockwise, that is, the valve is closed in the direction of the arrow pointing to S, and the valve is opened in the direction of O. where s stands for shut=off and o stands for open=on.

If there is a handwheel, rotating it in the direction of the right thumb is on, and vice versa.

The valve switch direction is generally closed clockwise, and it will be marked in special cases.

Under normal circumstances, all kinds of valves are clockwise is closed, counterclockwise is open. In special cases, there will be a special marked switch. Generally, it is in the shape of a handle, and if the handle and valve are in the same direction, they are fully open.

If there is a hand wheel, it is open to rotate in the direction of the right thumb, and vice versa, and if there is a handle, it is open along the pipe, and the handle is closed at 90 degrees from the pipe.

valves

Valve is a mechanical device that controls the flow, direction, pressure, temperature, etc. of the flowing fluid medium, and the valve is the basic component of the pipeline system. Valve fittings are technically the same as pumps and are often discussed as a separate category. The valve can be operated manually or with a handwheel, handle or pedal, and can also be controlled to change the pressure of the fluid medium.

Temperature and flow rate variations. Valves can be used to perform continuous or repetitive operation on these changes, such as safety valves installed in hot water systems or steamer boilers. In more complex control systems, automatic control valves are used as needed to regulate the changing set points of flow through the pipes based on external inputs.

The automatic control valve does not need to be operated manually, according to its input and settings, so that the valve can accurately control the requirements of the fluid medium. According to the material, the valve is also divided into cast iron valve, cast steel valve, stainless steel valve, chromium-molybdenum steel valve, chromium-molybdenum vanadium steel valve, duplex steel valve, plastic valve, non-standard customized and other valve materials.

In general, clockwise is off, counterclockwise is on.

Except for special requirements, the valves are clockwise is closed, counterclockwise is open, whether it is a faucet or a valve, round or with a handle, except for the double open, most of them are like this.

The design of closing the valve clockwise is more convenient, and the switch will generally be turned right to close the valve.

1. In which direction is the water pipe openUsually, the counterclockwise direction of the water pipe switch is open, and the clockwise direction is closed. If you can't turn the switch, you can look at the letters or markings on the switch to determine the direction. The O or Open end is open, the S or Shut Stop end is the Shut Pure.

The valves of the water pipes are the same, they all open counterclockwise and close clockwise.

Second, how to switch the direction of the main gate of the water pipe Generally speaking, the sluice used by many families is divided into two types. The first one is the ball valve. When the wrench of the ball valve is perpendicular to the water pipe, it means that the main gate of the water pipe is closed.

After twisting in the positive direction, the main gate of the water pipe is opened; The other is the gate valve, which rotates clockwise to indicate that the gate valve is closed. A counterclockwise rotation of the gate valve indicates that it is open. Regardless of the type of main gate, be careful not to over-tighten it during the tightening process to avoid the spool falling.

3. What should I do if the faucet rusts and can't be screwed.

1. Buy bolt loosening fluid, spray it for 2 minutes and then unscrew it. If it is not loose, you can use a hammer and other gentle taps a few times or dripping oil before twisting.

2. You can soak it in kerosene (kerosene perspective is very strong), and then pull it back and forth until it is loose before it can be removed.

3. Pour some boiling water on the faucet, then pour some gasoline on the faucet, and loosen it with pliers every 1 hour and wait for it to loosen.

The sluice valve is generally opened in a clockwise direction.

Generally, it is opened in a clockwise direction, and if there is an OFF and Lazhao ON logo on the sluice, it can be operated according to the direction of the sign, and the operation in the direction of ON is open. Because the sluice gate is not used often, it may rust after a long time, and if the user cannot open the sluice clockwise, it is necessary to remove the rust before opening the sluice.

Normal to the right is open, to the left is closed, the valve is usually closed clockwise, open counterclockwise, that is, along the arrow pointing to the direction of S is closed, along the arrow pointing to the direction of O is open, where S is shut, is also closed, O stands for open, is also open, if equipped with a hand wheel, then to the right thumb to rotate is open, and vice versa is closed.

Maintenance of sluice valves

In the process of use, the sluice gate needs to be cleaned frequently to ensure that the surface is clean and avoid affecting the use, and at the same time, it is also necessary to operate the sluice gate frequently to avoid the sluice gate not to appear rusty branches for a long time, and finally affect the opening and closing.

In the process of use, the sluice gate needs to be maintained regularly, and the specific maintenance method is to drip lubricating oil, which can effectively avoid rust on the sluice, and the operation of the wheel rental switch will be more flexible. The sluice gate is the main gate of the waterway in the house, and the safety must be ensured during use, if the failure is caused by special reasons, it is recommended not to repair it yourself, but immediately contact the property or water company to deal with it, so as not to expand the failure.
