How do I remove an old spool? How to disassemble the ball valve spool

Close the main water valve first, then put a red and blue mark of about 8 mm on the faucet handle, buckle it down, loosen the fixing screw counterclockwise with a flathead screwdriver, take off the handle, use a live wrench to disassemble the valve core of the faucet, use a wrench to open the upper part of the gland, and take out the ceramic valve core inside. Method 2: Close the main water valve first, you can use a screwdriver to insert under the handle of the faucet, pry left and right, pry it on the side, take it slowly, and the force is even and stable, so that you can remove the valve core.

Method 3: Close the main water valve first, unscrew the blue cover on the right handle, loosen the screws inside with a Phillips screwdriver, take off the handle, and the valve core will be exposed, and then use a movable wrench to unscrew the valve core. How do I replace the faucet spool with a new one?

After removing the spool, you will see a blue rubber ring on the bottom of the spool. It is generally customary to have a red rubber at the bottom of the left spool, while a blue rubber on the right spool. Therefore, when changing the valve core on the right, it is still necessary to use the blue rubber valve core, after the valve core is installed, the handle is plugged in, and the direction of the handwheel is adjusted.

Attach the screws and close the blue cap on the right, so that the new spool is replaced. The "simple method" of the faucet core identification 1: open and close the faucet handle, feel it with your hands, and whether there is a feeling of obstruction in the middle of the switch up and down!

If it is blocked, it means that it is not good) 2: Make the spool switch half as large and stop. And then hit into place!

Compare with the feeling, the upper half and the lower half feel are not the same! (Only a slightly high-grade spool can do this) 3: When the spool is left and right (adjusting the heat and cold)!

Use the above method first) and then look at the weight, a good valve core is "idling" when it is around, that is, it feels very light! 4: Use the index finger and middle finger to gently grip the faucet handle up and down and move it gently to see if it is flexible and not loose, whether there is a blocking feel, whether there is an oil damping feel, such as flexible and not loose, no blocking feel and a heavy oil damping feel can be bought!

The valve core is the valve part of the valve body with the help of its movement to achieve the basic function of direction control, pressure control or flow control. When rotating the rotating core, the fork at the lower end of the rotating core drives the driving valve plate to rotate, so that the water outlet through hole on the moving valve plate and the water inlet through hole on the static valve plate correspond to each other, and finally the water flows out from the through hole on the rotating core, and this design is widely used at the faucet water outlet. According to the mode of movement, it is divided into rotary type °) and translational type (radial and facing).

According to the shape, it can be generally divided into spherical (ball valve), conical (plug), round cake (butterfly valve and gate valve), round cap type (globe valve and check valve), cylindrical (reversing valve). Generally, it is mainly bronze or stainless steel, but there are also plastics, nylon, ceramics, glass, etc. The spool in a pressure reducing valve is one of the main components to achieve pressure control.

Method: Slowly knock the hole of the wall tile with a flathead screwdriver, unscrew the decorative cover counterclockwise, unscrew the bolt with a Phillips screwdriver, pull out the handle, and rotate the decorative cover counterclockwise.

The valve body is one of the main components in the valve; There are different methods of mechanical manufacturing depending on the pressure class. For example: casting, forging, etc.

The definition of "valve" is a device used to control the direction, pressure, and flow of fluid in a fluid system. A valve is a device that allows the flow of media (liquids, gases, powders) in pipes and equipment to flow or stop, and controls its flow.

The material of the valve body is different according to different process media.

Commonly used materials are: cast iron, cast steel, stainless steel, carbon steel, plastic, copper, etc.

Bodies of medium and low pressure specifications are usually produced using a casting process.

The body of the medium and high pressure specification is produced by forging process.

Together with the spool and seat seals, the seal is formed and can effectively withstand the pressure of the medium.

The above information refers to the encyclopedia - valve body

Method: 1. Disassemble the four bolts.

2. After the bolt is removed, the connecting pieces of the flanges on both sides are detached.

3. The valve seat sealing rings on both sides of the valve body can be deducted when the valve core is open.

4. Pull up the two cards of the buckle so that they no longer restrict the rotation of the nut.

5. Remove the parts on the stem.

6. Turn the valve core to the closed state before it can be taken out from the inside of the valve body.

7. Take out the valve body from the inside of the valve stem.

It depends on whether it's a bright or dark one! Generally, it is not difficult to disassemble, that is, after the sealing system of the shaft is removed first, the valve plate and valve shaft can be raised!

According to the connection form of the valve for the pipeline of a variety of connection forms, the most important of which are threaded, flanged and welded connections.

1.Threaded connection: This connection is usually the end of the valve inlet and outlet is machined into a cone or straight pipe thread, so that it is screwed into the threaded joint or pipe of the cone pipe.

Because of the potential for large leaking channels in such connections, sealants, sealing tapes, or fillers can be used to plug these channels. If the material of the valve body can be welded, seal welding can also be carried out after the threaded connection. If the material of the connecting parts is allowed to be welded, but the coefficient of expansion varies greatly, or the operating temperature varies widely, the threaded connection must be sealed welded.

The valves with threaded connection are mainly valves with a nominal diameter of less than 50mm. If the nominal diameter size is too large, it is very difficult to install and seal the connection. To facilitate the installation and removal of threaded valves, fittings can be used in the appropriate location of the piping system.

Valves with a nominal diameter of less than 50 mm can use a pipe sleeve as a pipe joint, and the thread of the pipe sleeve joint connects the two parts of the connection together.

2.Flange connection: The valve with flange connection is easy to install and disassemble.

However, it is heavier than the threaded connection, and the corresponding ** is also relatively high. Therefore, it can be applied to pipe connections with various diameters and pressures. However, when the temperature exceeds 350 °C, the load on the bolt is significantly reduced due to the creep relaxation of the bolts, gaskets and flanges, which may cause leaks in flange connections that are stressed a lot.

3.Welded connections: These connections are suitable for a wide range of pressures and temperatures and are more reliable than flanged connections when used in harsh conditions.

However, it is difficult to remove and reinstall welded valves, so their use is limited to applications where they usually operate reliably for long periods of time, or where the conditions of use are harsh and the temperatures are high. Such as thermal power stations, nuclear energy projects, ethylene projects on the pipeline.

1.Take the bonnet and spring.

2.Remove the shaft core, diaphragm, piston, etc., without damaging the diaphragm.

3.After taking out the above items, check whether the diaphragm and ring are damaged; If there is no damage, please do not divide the internal parts by yourself.

4.If you find that the diaphragm or ring is damaged, please loosen the nut on the shaft core, decompose the diaphragm or ring one by one, and replace it with a new diaphragm or ring after removal.

5.Inspect in detail whether there is any damage to the valve seat and shaft core inside the main valve, and clean it out if there are other debris inside the main valve.

6.Close the front and rear gate valves of the main valve first.

7.Loosen the piping fitting screws on the main bonnet to release the pressure in the valve.

8.Remove all screws, including the nuts that control the necessary copper tubing in the line.

9.In reverse order, the replaced parts are combined and installed with the main valve, and the valve can not be jammed.

What are you talking about upstairs? . . You are dismantling the water conservancy valve, and your gate valve will make me a spring and diaphragm for me to see. If you know a little bit of fur, you dare to come out. . . It's also a recommended answer.。。。 Sick.
