What should I do if the water pipe valve is slippery? What to do with the slippery screws of the wat

The solution of the sliding wire of the water pipe valve:

1. Shock: For rusty screws, do not use a wrench.

Tighten vigorously to avoid the six corners of the screw, the screw.

or a broken wrench screw. At this time, gently shake the handle of the wrench with a hammer, and the generally rusty screws can be shaken off.

2. Knock: Tap the edge of the square hammer to loosen the rusty nut easily. For example, the fixing bolt nuts at both ends of a bicycle pedal can be grabbed according to the thickness of the pedal and the metal structure.

The cast iron nut can be slightly larger, and the plastic should be gently tapped. If that still doesn't work, you can easily remove the nut by tapping it in the circumferential direction with a hammer.

3. Burning: Some screws are very rusty, and the above method still doesn't work, you can use "fire". Bake the screws and nuts thoroughly with a gas welding flame and then drop a little oil on the red screws and nuts.

The function of the heating screw is to expand the screw by heating. The function of the oil droplets is to make the screw shrink rapidly when it is cold, so that the gap between the screw and the nut increases, and when the oil flows in, the nut can be unscrewed. However, if there is plastic equipment nearby, use it with care.

4. Punching: Some parts of the top of the screw are corroded and deformed, which cannot be removed by wrenches and wire clamps, and the impact method can be used. First, use a hammer and a flat-bottomed screwdriver.

Hit the V-shaped groove on the top of the screw vertically. Then, adjust the angle of the punching cone and impact it in the direction of the screw. Once the screws are loosened, they can be unscrewed with tongs. The "one" or "ten" screw slide can also be screwed out in this way with the wire cutter.

5. Welding: It is not uncommon to break the screws when disassembling the equipment. Break the screws at the top, and generally do not use an electric drill.

Because the slightest mistake will break the wire hole. A better way is to weld a long piece of iron to a broken wire. Block of iron.

The cross-section is determined by the diameter of the screw. Once the iron is firmly welded, quickly drip oil onto the weld, saturating the nut. After cooling, the other end of the iron block is struck back and forth horizontally with a small iron cone. When the screw is loose, the wire can be broken by rotating the iron block.

Solution: 1. Use a hard object to get stuck on the edge of the slippery wire, and then use the corresponding screwdriver to slowly unscrew it, and the corresponding clip should also be slowly upwards accordingly, so that's it!

2. In daily life, there will always be contact with screws from time to time, such as bicycles, electric fans, hair dryers and other appliances. However, if the days go by, the screws (nuts) tend to rust, and sometimes they cannot be opened even if they are twisted with a wrench. What should I do?

Shock: For rusty screws, do not use a wrench to screw hard, in case you slip the six edges and corners of the screw, break the screw or break the wrench. At this time, you can use a hammer to gently shake the handle of the wrench, and the screws that are generally rusted can be vibrated and unscrewed.

Knock: Use the edge of the square-topped hammer to knock the rusted nut, which can easily loosen the nut. For example, the nuts that fix the bolts at both ends of the pedals of a bicycle can be struck with force according to the thickness of the pedal and the metal structure.

The nut at the cast iron can be used with a slightly larger force, and the plastic part should be gently beaten. If that doesn't work, you can easily remove the nut by tapping it in a circular motion with a hammer.

Burning: Some screws are very seriously corroded, and the above methods still do not work, so you can use "fire attack". Use a gas welding oxidation flame to grill the screws and nuts thoroughly, and then drip a trace of oil on the red-hot screws.

The purpose of heating the screw is to make the screw expand when heated. The purpose of dripping oil is to make the screw shrink quickly when cold, increase the gap between the screw and the nut, and the nut can be unscrewed after the oil flows in. However, if there are plastic devices nearby, use this method with caution.

Punching: The top of the screw of some devices is corroded and out of shape, and cannot be discharged with a wrench or wire cutter, which can be used by impact method. First, use a hammer and a top-level flat cone to impact a V-shaped groove in the vertical direction of the top of the screw, and then, adjust the angle of the punching cone and impact it in the direction of the screw, see Figure 2.

Once loosened, the screws can be screwed out with a wire cutter. When the "one" or "ten" screw sliding, this method can also be used to screw out the screw in combination with the wire cutter.

Soldering: When disassembling a device, it is not uncommon to unscrew the screws. For the screws with broken tops, electric drills are generally not used, because the slightest carelessness will drill the wire holes.

After the iron is firmly welded, oil is quickly dripped into the solder joint to soak the nut. After cooling, use a small iron cone to knock the other end of the iron back and forth in the horizontal direction, and when the screw is loose, rotate the iron to unscrew out the broken wire.

There are many ways to disassemble corroded screws, such as "oil arch", adding loosening agent, etc., as long as you are good at summarizing and using your brain, I think there is no "silk lump" that cannot be removed. ”

The easiest way to slip the nut is to abandon the "stubborn" screw, use a small electric drill or other tool to knock the nut off, remove the shell, use tweezers or nail clippers to remove the remaining screws, and replace the new screws.

It is best to replace it with a new one directly, as the slippery wire will cause the sealing strength of the interface to be insufficient and will leak.

If the pressure strength is not high, the tape can also be wrapped, and it can also be leak-proof.

If the pressure is high, it is recommended to change it directly!

Hope it helps!

Replace the valve, or buy the same valve and replace the spool.

Try to re-wrap some tape, but if it doesn't work, you can only replace it with a new one.

Pumping hoses appear in many places in our lives, and provide a lot of help for our lives, but are you familiar with pumping hoses? In fact, the pumping hose is often in contact with in daily life, a good pumping hose can make our life more convenient, so many defeated friends will buy a big brand of pumping hose, next, follow the introduction, let's get to know it together. So, what are the characteristics of a pumping hose?

What are the characteristics of a pumping hose.

1. Flexibility between pitches.

2. It has good elasticity, no blockage and stiffness.

3. Light weight and good caliber consistency.

4. Good flexibility, repetitive bending and flexibility.

5. Good corrosion resistance and high temperature resistance.

6. Anti-rat bite, good wear resistance, to prevent internal wires from being worn.

7. Strong bending resistance, tensile resistance and side pressure resistance.

8. Soft and smooth, easy to thread, install and position.

Pumping hose fitting steps.

1. First of all, confirm that the pipe is leaking and dripping. You can use a dry rag and dry one of the hoses first, the main surface is free of water. Then I will go and see later, if there is still water, it means that there is something wrong with this root; If there is no water, there is something wrong with the other one.

2. If the inlet pipe of the faucet is broken. Let's choose this kind of pipe. One end is big, the other end is small, and the small end is to be screwed into the faucet.

3. Then remove the faucet. The faucet is generally fixed to the sink or basin with screws, find the fixed nut, press it and it's OK. Then you can loosely unscrew the other end of the broken hose.

How to choose a pumping hose.

Aging resistance, superheated water resistance: EPDM has excellent weather resistance, ozone resistance, acid and alkali resistance, etc., and after 125 subheated water immersion for 15 months, the mechanical properties change very little, and the volume expansion rate is only. Since hot water needs to flow through the shower for a long time, EPDM is the best material for the hose.

Elasticity: The second is elasticity, we all know that when using hand showers, we need to stretch constantly to rinse the body, and EPDM molecular chains can maintain flexibility in a wide range, and can still be maintained in low positions, so this is one of the main reasons why designers choose EPDM.

Use a hard object to stick on the edge of the slippery wire, and then use the corresponding screwdriver to slowly unscrew it, and the corresponding clip should also be slowly upwards accordingly, so that's it!

In the threaded connection, the threaded connection cannot be snapped due to excessive force or other reasons that cause the thread to wear the thread, and the threaded connection cannot be tightened. From the perspective of physics, there are several reasons for the analysis of the "slippery silk" of the screwing wire: first, the force is too strong or too biased; Second, the wear of the device is too large; The third is that the quality of the material is too poor.

The difference between the British screws and the American screws is that the grinding angle of the British screws is 55 degrees, while the grinding angle of the American screws is 60 degrees, these two standard screws can be used most of the time, but the screws of 1 2 specifications cannot, because the standard thread of the British 1 2 is 1 2-12 teeth, and the American is 1 2-13 teeth.

Screw slip wire is the situation that the threaded connection cannot be snapped together and the threaded connection cannot be tightened due to excessive force or other reasons caused by the wear of the threaded thread.

Workaround:1. Use a hard object to get stuck on the edge of the slippery wire, and then use the corresponding screwdriver to slowly unscrew it;

2. Use gas welding oxidation flame to fully grill the screws and nuts, and then drip a trace of oil on the red-hot screws, and the purpose of heating the screws is to make the screws expand by heating. The purpose of dripping oil is to make the screw shrink quickly when cold, increase the gap between the screw and the nut, and the nut can be unscrewed after the oil flows in. However, if there are plastic devices nearby, use this method with caution.

3. Use the edge of the square-topped hammer to knock the rusted nut, which is easy to loosen the nut.

Hello dear! Is the valve spool slippery? 1.

The valve slide wire can be stuck on the edge of the slide with a hard object, and then slowly unscrewed with the corresponding driver, and the corresponding clip should be slowly upwards accordingly. However, it is best to install a new shut-off valve directly with the slag, as the slippery wire will cause the sealing strength of the interface to be insufficient and the water will not stop. Water pipe valves are forcibly sealed valves, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak.

2.When the medium enters the valve from the bottom of the valve disc, the resistance that needs to be overcome by the operating force is the friction between the valve stem and the packing material and the thrust generated by the pressure of the medium, and the force of closing the valve is greater than the force of opening the valve, so the straight diameter of the valve stem should be larger, otherwise the failure of the top bend of the valve stem will occur.
