Q:What gate DH10016, AM
The first Z represents the gate valve (the initial consonant of the Chinese phonetic alphabet for the gate); the second 2 represents the drive mode of the valve, that is, electro hydraulic drive.
Q:Gate valve, butterfly valve, ball valve advantages and disadvantages? What are the usual valves?
Steam traps: in steam, compressed air and other media, there will be some condensation water formation, in order to ensure the efficiency and safety of the device operation, should be timely discharge of these useless and harmful to the media, to ensure the consumption and use of the device. It has the following functions: 1. It can quickly eliminate the condensed water; prevent leakage of steam; remove air and other non condensable gases.Pressure reducing valve: by adjusting the inlet pressure to a certain outlet pressure, and rely on the energy of the medium itself, so that the outlet pressure automatically maintain a stable valve.Check valve: also known as reverse flow valve, check valve, back pressure valve and one-way valve. The valves are automatically driven and closed by the flow of the medium itself, belonging to an automatic valve. The check valve is used for piping system, the main function is to prevent the backflow of medium, prevent the reverse of pump and drive motor, and release the container medium. The check valve can also be used to provide a supply to the auxiliary system where the pressure may rise above the system pressure. It can be divided into swing type (rotating by gravity center) and lifting type (moving along the axis).
Q:About fire valve is gate valve or butterfly valve problems?
Disease is generally in accordance with the design requirements, regardless of the butterfly or tie hair to meet the requirements, are two-way valve.
Q:Z41T one 10 gate valve and Z44T one, 10 gate valve difference
Z41T one, 10 is single gate, Z44T one, 10 is double gateAccording to the provisions of the JB/T 308-2004 valve type programming method:Z== gate valve4== connection: flange type1== structure: Rigid single gate4== structure: Rigid double gateT== sealing surface material: copper alloy10== pressure rating: 1.0MPa
Q:Valve flange drawing n- up to what
A bolt hole used to indicate a flangeThe value of N indicates the number of bolt holesUp to the numerical representation of bolt hole size
Q:Does the tap belong to a stop valve or a gate valve?
When the valve is installed, the medium can enter from the bottom of the valve core and enter the two way from the top. Medium from the spool into the advantages of the valve closed when the packing is not under pressure, can extend the service life of the packing, and can be pressure in front of the valve in the case of replacement of packing work. Medium from the spool into the bottom of the shortcomings of the valve driving torque is larger, about 1.05~1.08 times above the entrance, the stem by the axial force of large, easy to bend the stem. To this end, the media from below to enter the way, generally only applicable to small caliber manual stop valve, to the valve closed, the media acting on the spool of force is not greater than 350kg limit. Electric cut-off valve is generally used to enter the media from the top way. The disadvantage of the medium entering from the top is just the opposite of the way it is entered below.Compared with the gate valve, the utility model has the advantages of simple structure, good sealing performance, and convenient manufacture and maintenance. The disadvantage is that the liquid resistance is large, and the opening and closing force is large. Gate and globe valves are fully open closed type valve, cut off or connected as the medium use, not as a control valve.The range of application of stop valves and gate valves is determined by their characteristics. In the smaller passages, the cut-off valve is used when required for better shutoff; in the steam pipe and the large diameter water supply pipe, the gate valve is generally used because of less fluid resistance.
Q:Why is gate valve or butterfly valve used for water pump?
General pressure is small, use the butterfly valve, when the pressure is big, use the gate valve. The two main function of the valve is to adjust the flow and easy to overhaul.Zibo Boshan new Duke water supply equipment
Q:Why the valve can only be fully open and fully closed valve can adjust the flow?
Valve, if adjusted, it is easy to wash the sealing surface, resulting in sealing surface damage.
Q:Pump adapter generally includes what accessories?
There is integration now.Pump adapter SQ100. All contain.
Q:Gate valve z45h-10dn250 length of the body?
Z45h-10dn250 body length L=330mm, this valve is hidden bar, elastic seat, sealing gate valve, gate lining, lining fluorine, belong to soft seal
