- Q: What are the differences between the pneumatic ball valve and the pneumatic angle seat valve?
- Features of pneumatic angle seat valve:1 、 visual position indication: it can be connected with limit switch or emergency manual device.2 、 easy to install: pneumatic head can rotate 360 degrees. One or two limit switches can be easily installed.3 、 advanced pneumatic controller: thickened engineering plastic shell, safe and reliable. Low wear piston structure with large capacity and low consumption. Self lubrication of internal components, maintenance free.4, with a variety of control methods: normally open, normally closed, double action.5. Require smaller pneumatic actuators: when the fluid flows over the stem, a smaller control head is optional.6, easy to connect: MAMUR standard connection, embedded metal connector.7, long-life Guide: Lease stem shaped Teflon (PTEE) sealed to avoid the import of stolen goods. Self lubrication, maintenance free. The stem is specially treated to ensure optimum fixation and automatically correct position.8. Without water hammer, the water hammer (water shock force) is absorbed when the fluid flows into the bottom of the valve stem.9, advanced valve body: flow is larger than ordinary angle block 30%, smaller size, better fluid flow pattern. 316 stainless steel body, Teflon seals, high temperature resistance, corrosion resistance. Life as high as seven million times
- Q: Heating live catch valve DN15 straight DN15 angle what does that mean?
- As shown in the figure: straight DN15 is: straight through both ends, such as diameter of 15mm, angle DN15 is: bifurcated end nominal diameter 15mm.
- Q: How does ball valve indicate?
- Valve type designation method is standard, the landlord himself to check the JB/T308 standard, Baidu library some, and is free to download:JB/T 308-2004 valve type method of preparation clear Edition
- 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: Advantages of track ball valves
- 1., the fluid resistance is small, and the coefficient of resistance is the same length as the pipe section. 2., simple structure, small size, light weight. 3., close and reliable, at present the ball valve sealing surface materials widely used plastic, good sealing, vacuum system has also been widely used. 4 easy operation, open and close rapidly, from fully open to fully closed as long as 90 degree rotation, facilitate remote control. 5., maintenance is convenient, ball valve structure is simple, the sealing ring is generally active, disassembly and replacement are more convenient. 6. in full open or full closed, the ball and valve seat sealing surface and dielectric isolation, the media through, it will not cause erosion of the valve sealing surface. 7., a wide range of applications, from small diameter to a few millimeters, large to several meters, from high vacuum, high pressure can be applied.
- Q: Why is there a water or oil in the new ball valve?
- The test has leaked;Pressure test, lubrication ah!
- Q: Daily maintenance of ball valve
- Longer service life and maintenance free period will depend on several factors: normal working conditions, maintaining a consistent temperature / pressure ratio, and reasonable corrosion dataBall valve in the closed state, there is still pressure fluid inside the valve bodyRemove the line pressure before servicing and leave the valve in the open positionDisconnect the power or air supply before servicingBefore the maintenance, remove the actuating mechanism from the bracketMust be found on the ball valve, the downstream pipeline has been removable pressure, in order to disassemble, disassemble operationIt is important to be careful not to damage the sealing surfaces of the parts, especially non-metallic parts, to remove the O rings. Use special tools when taking apart and re assemblingWhen assembling, the bolts on the flange must be symmetrical and tightened gradually and evenlyThe cleaning agent should be compatible with rubber, plastic, metal parts and working medium (such as gas) in the ball valve. When the working medium is gas, the metal parts can be cleaned by using gasoline (GB484-89). Non metallic parts are cleaned with pure water or alcoholThe non-metallic parts should be removed from the cleaning agent immediately after cleaning and should not be soaked for a long timeNeed 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: 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?
- Ball valve is 90 degrees switch, you may put the handle of the wrong position, change 90 degrees, try it
- Q: Structure design principle of fire ball valve
- The purpose of fire protection structure design of valve seat is:(1) effective guarantee in the fire accident, the upstream pressure medium as little as possible into the body cavity through the valve seat, thereby causing internal leakage and leakage. Ensure that fire accidents are not expanded by fire before the firemen arrive at the scene of the accident. After the firemen arrive at the scene, fire equipment can be used to quickly suppress the fire and eliminate fire accidents.(2) to make the structure of the product meets API6D specifications. Fire proof can be obtained through fire test.Fireproof design of valve seat:Set graphite in metal fire valve seat and valve body sealing rings; sealing set fireproof metal in the metal valve seat and ball room. The structure is shown in Figures 1 and 2.
- Q: Home tap water valve (ball valve) half open or well open, open half is not love rust live?
- The valve should be fully open the valve open the key is not half open it love rusted because the material inside is processed in general but you will not rust after scouring the semi open water surface changes so that it may be rusty (see you what material is the core surface treatment not original) and this makes serious at bad seat valve sealing effect was lostIn fact, it is necessary to use special control valve to control flow size ~!
