- Q: 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.
- Q: What are the uses and characteristics of copper ball valves?
- 4, good sealing performance5, the direction of installation is not limited, the flow of media can be arbitrary
- Q: What does "DN PN" mean? DN25 PN18 stands for what is the thickness? With the usual said 4 in charge of what's the relationship?
- Nominal diameter (nominal, diameter), also known as the average diameter (mean, outside, diameter).DN is nominal diameter, nominal diameter (or nominal diameter), that is, all kinds of pipe and pipe accessories of universal caliber. The pipes with the same nominal diameter can be connected with each other, so they are interchangeable. It is not the actual diameter or diameter of the pipe, although its value is close to or equal to the diameter of the pipe.In order to connect the pipe and pipe fittings in a unified way, nominal diameter (also called nominal diameter, nominal diameter) is adopted. For example, welded steel pipes can be divided into thin wall steel pipes, ordinary steel pipes and thickened steel pipes according to their thickness. Its nominal diameter is neither external diameter nor internal diameter, but a nominal size similar to the diameter of the ordinary steel pipe. Each nominal diameter corresponds to an outer diameter, and the inner diameter varies with the thickness. Nominal diameter can be expressed in metric mm, also available in English in. With nominal diameter pipeline accessories, meaning with tube.Nominal outer diameter is expressed by DN, refers to the outer diameter of the pipe. Such as the outer diameter of 32mm PVC-U pipe can be expressed as dn32. The specification of PVC-U pipe for building drainage is indicated by DN (nominal outer diameter) * e (pipe wall thickness) (GB-T, 5836.1-2006).
- Q: What is the ball valve core?
- Ball valve spool is the ball, valve opening and closing parts (sphere) driven by the stem, and around the stem axis rotation. More ball material, carbon steel, forged steel, ceramics and so on.
- Q: For our valve beginners, how intuitive decision is floating ball valve or fixed ball valve?

- Q: The toilet water pipe valve is broken, with a new twist, how are the screw does not move, then they told me to go on to the pipe on the water and then tighten, did as he said, really screwed, but do not know why, please tell the master what is the principle, if it is water without water when the screw does not move, but when the water can twist. What a kink!Is the water valve normal, a pull rod, pulling it back flush, do not rush the kind, the middle is a hollow ball
- I think it should be the water holding gas, connecting device principle, at the bottom of the hand, barometric pressure, and the best you can last map, I'll see
- Q: What is the difference between gas ball valve RQ11F-25P and ordinary stainless steel spike valve Q11F-25P?
- The models are all the same. What's the difference? Q ball valve, 1 internal thread, 1 floating through type, F PTFE sealing, 25=2.5mpa, P stainless steel.
- Q: For example, how many sizes and pressures are used in the two piece?
- A piece of ball valve, the current market pressure of most products below 6.4MPA, two piece ball valve about 12.8MPA products are also common, there are 20MPA, three pieces of ball valves are mostly below 6.4MPA. Know the characteristics and shortcomings of these three kinds of ball valves, you can completely choose according to your own needs.
- Q: Our factory has part of the ball valve in the direction of movement and normal ball valve is the opposite direction: anti clockwise for the turn off, clockwise. Excuse me, what's the reason for this?Excuse me, is this because the valve body installs the reason of the contrary or the reason, the ball valve is thus designed?Are there any positive and negative points when the ball valve is installed?
- Ordinary ball valve is the reverse turn off, the general ball valve without direction requirements. Each kind has the direction request, generally has the arrow or the nameplate explanation on the valve body.
