- Q:DN80/DN100/DN125 how big is the outer diameter of the ball valve flange?
- The outer diameter of the ball valve depends on what kind of flange you useAt present, the domestic commonly used flanges are marked with JB/T (formerly mechanical industry standard), GB/T (GB), HG (Ministry of chemical industry).
- Q:Pneumatic two stage ball valve principle
- Two section type pneumatic ball valve, pneumatic piston two stage shut-off valve to achieve a two step or two step off the action of the cut-off valve is a special pneumatic valve, provides 0 degrees, 45 degrees, 90 degrees or 0 degrees, 90 degrees, three operating mode 180 degrees.
- Q:How can the eccentric hemisphere valve be repaired? What are the things you should pay attention to when installing?
- Standard light valve professionals to answer for you, eccentric semi spherical valve installation methods and precautions:1. Check the cleanliness of the inner cavity of the valve before installation. Make sure the parts are perfect and no foreign objects can be installed.2, ball drive device breaking up, moving and electric way two, can be installed according to user needs, valve installation before test, start and shut two times. When after a period of time, there is a leak valve, adjustable manual and electric driving device for limiting the fastening bolt due to eccentric structure, can compensate for the wear, you must read the "manual and electric drive manual adjustment".3, eccentric axis and valve seat sealing adjustment, must be experienced personnel can be carried out.
- Q:What does "2P" ball valve mean?
- The left valve body and the right valve body consist of two parts.
- Q:Ball valve use?
- The utility model has the action of rotating 90 degrees, and the cock body is a sphere, and has a round through hole or a passage through its axis.
- Q:Three electric ball valve type T and type L what is the difference?
- Electric three way ball valve is a kind of valve, can be divided into L and T type.The T type can cause three orthogonal pipes to connect with each other and cut off third channels, thus diverting and merging the channels.Two pipeline L three ball type valve can only be connected mutually orthogonal, communicating with each other while maintaining the third pipeline, only as a distribution function.Type T and L type reversing diagrams are as follows:Turn left and turn right |
- Q:One stainless steel ball, two pieces, three pieces of difference, use
- Structural features of two piece ball valve:1, opening and closing without friction. This function completely solve the traditional valve because of the friction between the sealing surface and affect the sealing problem.2, top structure. The valve installed on the pipeline can be directly checked and maintained, which can effectively reduce the device parking and reduce the cost.3, single seat design. The utility model eliminates the problem that the medium of the valve in the valve is influenced by the abnormal voltage increase.4 、 low torque design. Special structural design of the valve stem, with only a small hand, the valve can easily open and close.5 wedge sealing structure. Valve is provided by the mechanical force of the valve stem, the ball wedge to the seat and seal, so that the valve sealing is not affected by changes in pipe pressure, in a variety of conditions, sealing performance has a reliable guarantee.6. Self-cleaning structure of sealing surface. When the ball roll off the seat when the fluid in the pipeline along the sealing surface of the sphere into 360 degrees evenly through, not only eliminates the high speed fluid on the seat of local scour, also washed away the sediment on the sealing face, achieve the purpose of cleaning.
- Q:What is the nominal pressure 1.6p of a ball valve?
- Nominal pressure: reference value relating to the pressure resistance of a piping system. For ease of use, usually the priority of the R10 series is taken. Nominal pressure refers to the pipe in the two temperature (20 degrees Celsius) when the water delivery pressure. If the water temperature is between 25 and -45 degrees, the coefficient of temperature drop should be adjusted to correct the working pressure.
- Q:Structure design principle of fire ball valve
- The fire ball is fixed ball structure, the upper end of the main seal seal, the seal has the function of DBB, in good condition, the valve in the fully open or fully closed state, the cavity in the outfall or vent to observe the upstream seat leaks. Pipeline ball valve in normal use, the middle chamber without pressure. In the case of fire accidents, a reasonable design of the fire protection structure of the valve seat can slow down the progress of the upstream pressure medium into the middle cavity, and avoid the leakage and leakage of the medium caused by the boosting of the middle cavity. The valve seat with good fire protection design is an active measure to ensure the safety and fire resistance of the pipeline ball valve.The fireproof structure design, the design of the seat structure fire is the key, the seat of the fire performance is good, in the fire accident condition, fire structure design of the pressure between the body and the stem structure, reduce the fire around the body.
- Q:What's the difference between air valves, butterfly valves and ball valves?
- On the pipeline, mainly from cutting and throttling.Butterfly valve headstock is a disc shaped disc, in the valve body around its own axis of rotation, so as to achieve the purpose of opening or closing or regulation.Ball valve: opening and closing parts (sphere) driven by the stem, and around the square ball valve for the axis of the rotating valve.Shanghai Guardian valve, all types of valves are industry-leading.
