FAQ

Here, the original water leakage, has not been closed, recently closed for other places, twisted two times, and now it is so,Ball valve leakage of this place, how do? Here, the original water leakage, has not been closed, recently closed for other places, twisted two times, and now it is the case, how can I ask?

It may be there when rust, so the Water Leakage, move it off slowly, rust, water Heicha out.

What's the meaning of the double ball valve in the double ball valve?

By means of "union", the "live" means that the two ends of the valve are connected by a live joint

Open the pressure relief valve core hole with what

Attention to maintenance methods of eccentric hemisphere valve:1, eccentric hemisphere valve in the closed state, there is still pressure fluid inside the valve body.2 、 before repair, release the line pressure and make the valve in the open position.3. New parts should be cleaned before assembly.4. Remove the actuating mechanism from the support before servicing.5, non-metallic parts cleaning should be immediately removed from the cleaning agent, not long immersion.6, need to be cleaned by washing the wall after volatile cleaning agent (cleaning agent can not dip silk rub) for assembly, but not for a long time on hold, otherwise it will rust, dust pollution.

The hot water pipe ball valve what brand alone?

The rn angle valves are generally new home decoration essential water heating accessories, and play the role of a beautiful.

Daily maintenance of ball valve

The new parts need to be cleaned before assemblingThe assembly should have metal fragments, fiber, fat is not allowed (except the requirement to use) dust and other impurities, foreign matter contamination, adhesion or remain in part into the cavity on the surface or, if the packing is micro discharge, to lock the stem nut.Note: do not lock too tight, usually lock 1/4 circle to 1 laps, the leak will stop.(A) disassemblyMake the valve in a half open position, flush and remove dangerous substances that may exist inside and outside the valve body.Close the ball valve, remove the connecting bolts and nuts on both sides of the flange, and then remove the valve completely from the line.In order to remove the drive - actuator, a connecting bracket, lock washer, stem nut, butterfly spring, glam, wear plates, valve stem packing.Remove the body cap connecting bolts and nuts, separate the valve cover from the valve body and take off the valve cover washer.Make sure the ball is in the "off" position, which can be easily removed from the valve body and then removed from the valve seat.A hole in the body downward nudge stem until completely removed, and then remove the packing ring and the O.Caution: Please operate carefully to avoid galling, stem surfaces and body packing box seals.B) reassembleCleaning and inspection of the parts removed, it is strongly recommended to use spare parts package replacement valve seat and valve cover, gaskets and other seals.Assemble in reverse order of disassembly.Cross the locking flange bolts with the specified torque.Lock the stem nut with the specified torque.

What's English for ball valves?

Check valve/ball vavle/globe valve (ball valve), there are three kinds of translation, see which you preferFast stainless steel ball valve, ball valve is evolved from the plug valve. It has the same rotation, 90 degrees lifting action, and the difference is that the cock body is a sphere and has a circular through hole or passage through its axis. The ratio of the sphere to the channel opening should be this, i.e., when the ball rotates 90 degrees, the spherical surface should be fully presented at the inlet and outlet, thus truncating the flow. The ball valve only needs to rotate 90 degrees of operation and very small turning moment can close tight. Full equality of the valve cavity for the media to provide a small resistance, through the flow channel. It is generally believed that the ball valve is suitable for direct opening and closing, but the development of the ball valve has been designed to make it throttling and controlling the flow.

What's the advantage of using an electric ball valve?

Shanghai power code solenoid valve on the official website introduced the benefits of four point electric ball valve, 1. for two cutting, adjusting the occasion. 2., electric ball valve can be achieved on the petroleum, chemical, paper, metallurgy, sewage treatment, oil tanks and other transport pipeline cutting off the medium and circulation. 3., good sealing performance, large flow capacity, convenient handling and maintenance, small flow resistance, reliable sealing, and even cut off. 4. 、 electric valve is small, light weight, big thrust, powerful function, servo amplifier built-in, easy to operate, high reliability.

What is the difference between ball valve and plug valve?

Plug valves are closed or plunger shaped rotary valve, through the rotation of 90 degrees to make the valve plug on the mouth of the channel with the valve on the mouth of the same or separated, to achieve a valve opening or closing. Plug valve plug shape can be cylindrical or conical. In the cylindrical valve plug, the channel is generally rectangular; in the tapered valve plug, the channel is trapezoidal. These shapes make the structure of the plug valve lighter, but at the same time a certain loss. Plug valves are most suitable for cutting and turning on the medium and for shunting applications, but in accordance with the applicable nature and sealing surface erosion resistance, sometimes also used for throttling. As the plug seal between the movement with a wipe action, while fully open, you can completely prevent the contact with the flow medium, it is usually also used for suspension with particles of media. Another important feature of the plug valve, it is easy to adapt to multi-channel structure, so that a valve can get two, three, or even four different flow channels. This simplifies the design of the piping system, reduces the amount of valve used, and some connecting fittings needed in the equipment.Plug valves use:Plug valves are widely used in oil production, transportation and refining equipment, but also widely used in petroleum, chemical, chemical, gas, liquefied petroleum gas, HVAC and general industries.
