Suitable for gear operators, electric and pneumatic control actuators.
- Q: What does gate valve Z44T-10-200 code mean?
- The meaning of the model 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 EditionHttp://wenku.baidu /view/5f798850ad02de80d4d84036.htmlZ = gate valve4 = connection: flange4 = structure form: double gateT = sealing surface material: Copper10 = nominal pressure: 1.0MPa, followed by no letters indicate body material: Cast Iron200 = nominal path: DN200
- Q: What is gate valve (with force transfer joint)?
- Flange valve is equipped with a force expansion joints, easy installation
- Q: Why the valve can only be fully open and fully closed valve can adjust the flow?
- You said the cut-off valve is that the spool is rotating rather than vertical movement structure?Theoretically, the flow regulation can be realized by controlling the position (angle or distance), and all of them have mature products.
- Q: What are the common standards for gate valves?
- Is the gate valve opening and closing parts, RAM direction of motion perpendicular to the direction of the fluid, valve can only be fully open and fully closed, can not be adjusted and the throttle. The following common standards for Fujian Biaoguang valve for valve: design specification: JB/T 7746, API602 JB/T 7746, the length of the structure specification / thread socket factory test and inspection of JB/T1751/GB7306, ANSI: B16.11/B2.1: JB/T 9092, API598 pressure temperature: GB/T 9131, ANSI B16.34, MSS GB/T 12220 product ID: SP25 delivery specification: JB/T 7928
- Q: What is the difference between an elastic gate valve and a rigid gate?
- General rigid gate used in the temperature is not too high, the pressure is not too large occasions, flexible gate used in high temperature, high pressure, or relatively high sealing requirements.Valve closed, the sealing surface can only rely on medium pressure to seal, that is to rely on medium pressure to the gate sealing surface pressure to the other side of the seat to ensure the sealing surface seal, which is self sealing. Most of the valve is forced seal, that is, when the valve closes, to rely on external force to force the gate to the seat, in order to ensure the sealing surface sealing.
- 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: What does valve qz45x - 10q mean?
- Crown valve pressWhat does Q stand for? I'm not sure. It's probably made of ductile iron"Z" means "gate valve"4 represents flange connection5 represents the dark bar (1 represents the Ming pole)X stands for rubber seal and soft seal10q stands for 10 pressure
- Q: Which is the most expensive, check valve and gate valve?
- In the case of DN50 Z15T-16 DN50: screw valve 46.200 thread copper bar gate valve Z15T-16 DN50 52 Z45F-16 DN50 97 flange valve flange valve rod Z44T-10 DN50 169 Z45T-116 DN50 flange valve dark bar 173 thread swing check valves DN50 52.090 thread straight type check valve DN50 57.280 flange screw check H44T DN50 129 flange valve lift check valve H41T-16 DN50 124
- Q: Acid resistant alkali valve gate valve
- Fluorine gate valve; material: carbon steel, cast iron; design standards: JB, GB, ANSI, BS, API, ISO, DIN, NFZ, lining valve;
- Q: Why does the centrifugal pump start and stop in the case of closing the gate valve?
- Centrifugal pump to close the gate valve in the case of the start: the centrifugal pump power increases with its flow rate, when the flow is zero (valve closed), the minimum power to operate. Start the valve off from the angle of the motor. If the valve is started, the motor itself to start the current is larger, coupled with the power of the pump is also large, easy to cause the motor over-current trip, serious will burn the motor.
