- Q: Electric ball valve installation need to pay attention to what?
- 3, valve installation should be detailed understanding of its performance and features; 4, valve installation space to ensure the ease of use, maintenance and repair simple. 5, in order to avoid loose screws, bolts of leakage, before use each fastening screws; 6, in the use of the process should pay attention to the use of medium pressure valve, such as temperature, so as to avoid damage to the valve; 7, such as the valve opening and closing in, should identify the reasons, troubleshooting, no knock, smashing etc. method of forced opening and closing.
- Q: What's the difference between angle valve and ball valve?
- Ball valve, as its name suggests, is the shape of a ball valve, water from the hole in the middle of the ball out, usually the handle to control the opening and closing. But the ball valve can only be switched on and off, and can not adjust the flow. To put it plainly, you take it half open and half closed, and its flow is not about 50%, and fluctuates greatly. In addition, if the ball valve will be half closed, it will damage the ball valve, greatly shorten its life. Ball valve is mainly used for heating hot and cold water inlet pipe.
- Q: What's the diameter of the 4 point ball valve?
- 4 points is 0.4 inches, 1 inches =25.4 mm.Then the 4 point ball valve diameter is 10.16mm.
- Q: DN15 ball valve with a bit of outer wire
- Outside the wire of 1/2, which is DN15, the wire wire twisted together just bite
- Q: PPR ball valve diameter is 3 cm, what is the specifications?
- Closer to the national standard, the size should be 32 (phi 32)
- 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: What are the differences and advantages between O ball valve and V ball valve?
- 5, high reliability1, the ball and valve seat a pair of sealing pairs, there will be no abrasions, rapid friction and other failures;2, stem into the built-in type, to eliminate the stem under the action of fluid pressure may be caused by the packing gland release flying accident hidden trouble;3 、 adopt antistatic and fireproof structure ball valve, which can be used to transport petroleum, natural gas and gas pipelinesV type ball valve structure of a right angle turn, can achieve flow regulation, according to the V type angle V type sphere, realize different proportions, V type ball valve and valve actuator and positioner supporting the use, the ratio can be adjusted V type valve adjustment for a variety of occasions, with a rated flow coefficient large, adjustable ratio, good sealing effect, regulate the performance of zero sensitivity, small size, can be vertical horizontal installation. For control of gas, steam and liquid medium.V type ball valve for rotary type rectangular structure by V type valve, pneumatic actuator, positioner and other accessories; there is a similar more than 100 of the inherent flow characteristics; dual bearing structure, the starting torque is small, with excellent sensitivity and speed sensors, the shear capacity of strong.
- 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: Hello, I would like to ask the household tap water valve selection of stainless steel ball valve or brass ball valve is better, thank you
- I have used two kinds, but stainless steel gate valve is better. Note that it must be made of stainless steel 304. I bought more than 300 yuan a gate valve. Total valve, no way to save money.
- Q: What's a twin hot melt ball valve?
- The ball valve is defined with the ppR/PE hot melt plastic pipe connected with the ball valve hot melt connection, ordinary ball valves generally use the threaded connection or flange connection. Double hot melt ball valve is both ends of the hot melt way to connect the ball valve
