Q:Can the soft seal gate valve reach 25 kg?
Soft seal butterfly valve seal is good, but can only withstand up to 16 pressure, or the plastic can not stand. A short period of time is OK, and it's also related to the workmanship and quality of the factory. The quality is poor.
Q:What's the difference between open rod gate and dark rod gate valve?
3, dark rod valve is located inside of the body, in the process of opening and closing, stem only rotation move, the gate in the valve body lifting; the valve stem rod driven gate valve with the valve stem of the lifting drive thread in the external body, according to the direction of movement of the stem and the position of judge the gate opening and closing and position;
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.com/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 type of flange does it fit with the gate valve?
According to the welding plate flange, flange material selection of piping material.
Q:What are the advantages and disadvantages of flat gate valves?
The advantage of flat gate valve is that the flow resistance is small, and the flow resistance is similar to the flow resistance of short valve. The flat gate valve with guide hole is installed on the pipeline and can be directly cleaned with the cleaner. As the gate is sliding on the two seat surface, the flat gate valve can be applied to the medium with suspended particles, and the sealing surface of the flat gate valve is actually positioned automatically. The seat seal surface is not subject to thermal deformation of the valve body. Moreover, even if the valve is closed in cold condition, the thermal elongation of the stem will not cause the seal to be subjected to overload. The length of the structure is much shorter than that of the ball valve, and it is easier to start. Light plate gate valve is more refined, but the effect is exactly the same.The disadvantage of flat gate valve is that when the medium pressure is low, the sealing force of the metal sealing surface is insufficient, so as to achieve satisfactory sealing. On the contrary, when the medium pressure is high, if the sealing surface is not lubricated by the system media or foreign media, often opening and closing may cause the sealing surface to wear too much. Another disadvantage is that the circular motion of the circular gate in the circular flow, only when it is at the valve closed position of 50%, this valve is more sensitive to flow control. Moreover, the gate will produce severe vibration when it breaks the high-speed and dense medium flow. The valve seat can also be throttled if the seat is made of a V - shaped opening and is tightly oriented to the gate.
Q:What are the features and uses of the gate valve?
1) advantages: sealing performance than the cut-off valve, the fluid resistance is small, open and close more effort, full sealing surface by the erosion of media, media flows from the restrictions, with double flow, small structure length, wide application range. 2) disadvantages: high size, open need a certain space, opening and closing time is long, in the opening and closing, the sealing surface is easy to erode and scratch, and the two sealing pairs bring difficulties to the processing and maintenance.3) use: gate valve is generally used in the caliber of DN15-1800mm pipes and equipment, and its dosage is great, mainly cutting off function, not allowed to throttle.
Q:What is the Z15T-16C letter of the gate valve?
The Z class code indicates the type of gate valve, gate valve is the first letter of the alphabet. The gate is manual driving mode, 1 said the connection form of gate valve for connecting thread, 5 represents the structure form of gate valve for rigid single gate, T gate said lining material of copper alloy, 16 PN1.6MPa nominal pressure valve. C said the valve body material is carbon steel.
Q:What is the difference between the copper gate valve and the ordinary material gate valve?!
The copper gate valve is made of copper alloy, and the common materials are made of stainless steel, cast steel, cast iron, and so on. Now there are new types of ceramic gate valves. Different properties of the gate valve performance, processing technology, service life, applicable occasions are a certain difference. Copper gate valves should be used for fire end water outlet installations as well as other occasions with special requirements.
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:What does gate valve do?
Gate valve structure, upstairs said about the same, but it can only rough adjustment flow, you may drive it to 30%, he will flow through 65% traffic, you can drive him to 70%, he also flow through 75% traffic. However, the fluctuation is small and can be used for rough adjustment of flow. What's more, half open and half closed are some of the effects on their life span.
