- Q: Is the ball valve installed in a direction?
- Valve installation generally no direction required, any end of the valve can be mounted on the upper end. If the valve marked the direction, then it should be installed in the direction of tagging installed.
- Q: What is the difference between floating and fixed ball valves?
- Fixed ball valve is the ball with the lower stem fixed, pressure will not produce movement, therefore, in the design, two sealing ring must have sufficient preload to ensure that the valve seat and sphere seal, is a two sided forced seal. Thrust or sliding bearings are usually provided on the upper and lower stems of the ball.
- Q: Is the stainless steel ball valve forged steel ball? Which one is suitable for the gas pipeline? (FAQ
- This does not mean cast steel can not be used. Cast steel is also acceptable because all the check valves and control valves of natural gas lines are cast. But the casting process has a high probability of defects.
- Q: How much pressure DN65 ball valve?
- DN65 represents the nominal diameter of the valve, which is known as "2 and a half inches" of the ball valve!How big is the pressure? The pressure is expressed in PN, and the pressure levels are divided into: PN0.6, PN1.0, PN1.6, PN2.0, PN2.5, etc.
- 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.
- Q: And the cut-off valve is not the general name of gate valve and butterfly valve?What are the signs of differentiation?How about the use?
- When the valve is opened, the opening height of the valve is 25% to 30% of the nominal diameter, the flow has reached the maximum, which means that the valve has reached full open position, so the opening position of the stop valve should be determined by the stroke of the discThe cut-off valve has the following advantages:The utility model has the advantages of simple structure and convenient manufacture and maintenanceSmall travel time, short opening and closing timeGood sealing, friction between the sealing surface of small, long lifeThe disadvantages of the cut-off valve are as follows:The resistance of fluid is large, and the force required for opening and closing is largerNot suitable for medium with particle, viscosity and easy cokingPoor regulation performanceType valve stem according to the position of divided threaded screw type, internal thread. Divided by the flow of media, there are straight through, DC type and angle type. Divided by the form of valve seal, a packing seal bellows seal valves and valve.The installation and maintenance of the cut-off valve shall pay attention to the following matters:The stop valve operated by the handwheel and handle can be installed in any position of the pipeHand wheel, handle and steering mechanism are not allowed to be used for liftingThe flow direction of the medium shall be in accordance with the arrow shown in the valve body
- 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?
- First, 170psi pressure is not great, not excessive extrusion and rupture of polyethylene, but there will be stress relaxation phenomenon, is a long time there will be some loose, suggest you nut and pipe with tight mechanical connection is good, the data has not been studied, can only give you a suggestion: 24-48 hours after the installation is complete then a proper tight.
- Q: Ball valve Q41f and Q11f difference, whether universal?
- Generic. The Q41F 4 stands for flanged connections, and the Q11F 1 represents the internally ribbed pipe
- Q: What type of ball valve is Q17F-10T?
- Q17F-10T is copper and copper alloy internal thread, L type three way ball valve, is fixed ball
- Q: DN20 pressure 6000PSI, one piece of thread on the threaded, full diameter ball valve body length and flow hole to how much?
- 1, the valve body and the valve cover as a whole bear cavity, must meet the design manual on the minimum wall thickness requirements, at the same time to add corrosion allowance, at the same time calculation, large value as the wall thickness of 2, then according to the height of gate valve diameter, to ensure that the valve in the fully open under the condition, ensure the seal and the valve cover seal gate, so that we can determine the height of
