Q:Butterfly micro stop type check valve HH46XP-10Q, what does the letter mean?
The first H stands for slow closing, the second H represents the check valve, the X represents the sealing surface, and the rubber, the P represents the butterfly plate, and the stainless steel Q represents the ductile iron.
Q:What is the air pipe check valve?
One-way valve, one-way flow, to prevent negative pressure reflux.
Q:The difference between check valve and check valve
The same thing, called, is based on the difference in the use of the actionFor example, overflow valve and safety valve, back pressure valve, are the same thing, are in the one-way valve behind the increase of back pressure spring
Q:What kind of valve does the check valve belong to?
1. check valves are automatic valves;2., if the valve is cast iron, can be cast iron valves; if the valve is cast steel, can be cast steel valves; of course, can also beIn copper valves, stainless steel valves,,,,,,,3., if used in steam, can belong to the steam valve
Q:I also calculate each pump check valve and gate valve?
The pump adapter itself does not include the gate valve and the check valve! Only when a group called pump adapter will include adapter, gate valve and check valve!If the pump adapter in the list of units for the group then all included and work content in clear note on the contents.If you do it alone, write out no items!
Q:Why is the intelligent water meter equipped with a check valve, still can not prevent the water meter idling?
2.3 installation methods and installation quality2.3.1 since the water meter is now out of the door, most of the units are all concentrated in one box and installed on the first floor. Taking into account the freezing cold winter and the meter, with 6 or 12 meter with a diameter of 40mm- 50mm diameter pipe, tables and small spacing and straight sections set aside less water, this will also affect the normal water metering, causing water rotation.2.3.2 installation quality, pipeline projects are basically buried in the ground or in the wall, is a hidden project. National construction standard pipe provides various pipe pipeline construction installation requirements, construction process, acceptance criteria and matters needing attention, but in the construction site, some managers do not according to the requirements of the code construction, more or less there are some quality problems caused by pipeline.
Q:What is the structure of the check valve of the screw air compressor?
Work process: air pre filter, and then through the air filter and the air inlet controller into the mixing chamber and the compression screw lubricating oil, continuous linear by asymmetric rotor two, compression. The compressed oil and gas mixture enters the tank and the separation system for three levels of separation (centrifugal, self weight, and fine separation). The separated compressed air is discharged after the cooler is cooled, and a reliable pressure switch system controls the exhaust pressure. When the machine is running, the screw compressor run oil system by pressure difference automatic circulation, without pump. When starting, the minimum pressure valve is closed to ensure the minimum pressure required for the lubrication oil circulation. In addition to lubrication, the oil also acts as sealing, cooling and reducing noise. High efficiency oil and gas separator and high efficiency cooler ensure high quality compressed air.
Q:What does the swing check valve "h44h-16" mean?
H44h-16 is the type of swing check valve, respectively: H check valve, 4 flange, 4 swing type H alloy steel, sealing 16 kg pressure
Q:What is the HH44X-16 H of the double acting slow closing check valve? Can you explain it in detail?
2, micro resistance, slow closing check valve, also known as check valve, its role is to prevent the medium back in the pipeline. The opening and closing parts depend on the flow of the medium and the power is turned on or off by itself. The valve that prevents the backflow of the medium is called a check valve. Check valves belong to the automatic valve, mainly used for one-way flow of media channels, allowing only medium to flow in one direction, to prevent accidents. Suitable for cleaning medium, not suitable for medium containing solid particles and viscosity.
Q:What is the function of the check valve?
1. Check valve function: prevent backflow of medium, prevent pump and drive motor reverse, and discharge of container medium.2, check valve refers to rely on the flow of the media itself and automatically open and close the valve, used to prevent the media back of the valve, also known as check valve, one-way valve, counter flow valve, and back pressure valve. The check valve belongs to an automatic valve.3, check valve according to the structure of the division, can be divided into lift check valve, swing check valve and butterfly check valve three:Lift check valve is divided into two types of vertical and horizontal.Swing check valve is divided into single, double valve and multi flap type of three.Butterfly check valve is straight through type.The above types of check valves can be classified into thread connection, flange connection, welding connection and clamp connection in connection forms of four kinds.4, check valve (Check, Valve) installation should pay attention to the following mattersA do not allow the check valve to bear weight in the line, and the large check valve shall be independently supported so as not to be affected by the pressure generated by the piping system.B, when installing, pay attention to the direction of the flow of medium should be in accordance with the direction of the body marked arrow.C and vertical vertical check valves shall be installed on the vertical pipe.D and lift type horizontal check valves shall be installed on horizontal pipes.
We mainly produce various check valves (for example,single disc swing check valve,double disc swing check valve,ball check valve,lift check valve, butterfly valves,diaphragm valves ,ball valves and so on). Our products are widely used in municipal water and wastewater ,oil,chemical, food and other fields.Our entire valves are designed and manufactured according to ANSI (ASME), DIN, BS, JIS and other standard. Also, we ensure the best quality for customers, and our strict quality assurances systems are conducted throughout the entire production at the standard of ISO9001:2008 and CE.
