Q:O ball as general regulation of opening extent

Hard seal can be adjusted, soft sealed, please be careful.The opening 0~90 curve is getting faster and faster

Q:Electric ball valve installation need to pay attention to what?

High valve valve installation tips using general notes 1, the single pole light to put Ji GUI lice before installing the valve should be cleaning the dust inside the pipe with stiff, welding slag and other impurities; connected with the valve connection standard standards 2, pipeline, operating conditions and valve performance.

Q:Stainless steel ball valve, Q11F-10P, 16P, 11F, what does that mean?

The first 1 that connect the second ball, 1 straight through valve, F PTFE sealing.

Q:What q25r-j159 BB-F-TE-NB represents American Standard ball?

Each letter has different meanings. Such as model, connection mode, material, driving mode, etc.%021 $3461#$%9331^^ hope Shanghai Yiling valve to help you answer

Q:What does "DN25 Q41F46-16C" mean?

DN is nominal diameter, nominal diameter (or nominal diameter), that is, all kinds of pipe and pipe accessories of general diameter of 25 mm

Q:The working principle of the track type ball valve

With its unique structure, the spool rotation separation open, new technology design of mechanical seal pressure, is the most prominent advantages of the sealing surface does not produce friction, long service life, low operation torque, even if the medium water content of solid particles, sediment, short fiber and other impurities, high concentration fluid flushing sealing condition of body harsh, can maintain good sealing, to ensure the engineering equipment maintenance period in the safe and reliable operation.

Q:What does "ball valve" Q41F-10P mean?

Q valve (Qiu represents the first letter of the alphabet), 4 representative flange, second representative is 1 ball valve floating ball (ball valve floating ball and fixed ball, 7 ball, F fixed on behalf of) on behalf of PTFE- PTFE seal (PTFE PTFE), representing 10 of the nominal pressure valve is 10 kg (1.0Mpa), P represents the valve body material is 304 stainless steel.Soft sealing stainless steel flanged ball valve

Q:For the master enlighten Q47 ball seat spring hole number is determined by how

Calculate each spring force, multiplied by the number. According to the manual valve design must be greater than the pressure, pressure ratio must be large than the material allowable pressure on the line. (emphasize that here because the production process of the spring, has value of many uncertain factors, so the actual production of the spring and you cannot calculate out the same, so please choose when to consider).

Q:PE pipe size diameter 3/8, diameter 1/4, material: low density polyethylene, pressure 170psi;Valve material: copper, and PE pipe connection interface with lock nut.Is this connection reliable? Will the pipe break due to excessive compression? Are there any requirements for the size of the joint and the size of the nut?

After the impact, for a period of time, PE pipe cracking phenomenon, this is what causes? This is connected to the tap water.Chasing the answerWhere is it cracked?!

Q:Maintenance of PPR pipe ball valve is live or hot melt?

CharacteristicFirst, wear-resisting; because the hard sealing ball valve spool is alloy steel spray welding, sealing ring is alloy steel surfacing, so hard sealing ball valve in the switch will not cause too much wear and tear. (its coefficient of hardness is 65-70)Two, good sealing performance; because the hard sealing ball valve sealing is artificial grinding, until the valve core and the sealing ring completely in conformity with the use. So his sealing performance is reliable.Three, switch light; because the hard sealing ball valve sealing ring at the bottom of the spring, so that the sealing ring and valve tightly held together, so when the outside force exceeds the preload of the spring, the switch is very light.Four, long service life: has been widely used in petroleum, chemical, power generation, paper making, atomic energy, aviation, rockets and other departments, as well as people's daily life.
