What does the check valve VHRS63CB010 250 mean?

Here are some of the well-known brands recognized in the valve industry, which are widely recognized and have a high reputation. While rankings may vary depending on time and market conditions, the following brands are generally considered to be among the top brands in the valve industry:

The following influential first-line brands of water system valves and industrial valves can be used as a reference, but for reference only: Suzhou Neway Valve, Shanghai Guanlong Valve, Shanghai Qizhong Valve, Sanhua, Su Yan, Shentong, Su Valve, Nanfang, Jiang.

First, the word Yao. The above manufacturers are only estimates and references, and the specific situation may vary or fluctuate at any time due to changes in a series of factors such as changes in the market, the size of the competition pattern, and the stability of product quality. As an indispensable key device in industrial production and civil facilities, the quality and reputation of the valve brand directly affect the satisfaction and trust of users.

These brands are known in the valve industry for their innovative technology, high-quality products and reliability. It is important to note that the market and industry are evolving rapidly, and different rankings may vary depending on time and region. For the most up-to-date ranking information, it is recommended to refer to industry reports, professional organizations or market research data for more detailed and accurate information.

According to the valve code of Ningbo Engineering Company.

v valve. h Check valve.

r flange rf

s Bolt-on bonnet, swing-on check valve.

63 pressure grade CL300

CB Body Material ASTM A216

01 Trim Sealing surface material API 1 13Cr 13Cr

This is the pressure level of the valve, which is 16kg, and is used for pipeline equipment where the pipe pressure is less than this pressure.

b AC arc welding power supply, x represents the descending characteristic, 250 means the maximum welding current output is 250 amperes, and 1 represents the moving core type. It's absolutely professional.

B Table AC x Table Drop Characteristics 1 Moving Iron 250 Maximum Welding Current.

Not really.

Taking model aircraft motors as an example, China's model brushless motors are roughly divided into 3 series:

A series - inside the brushless motor in the inner rotor slot (stator winding surrounding.

It is contained on a slotted silicon steel sheet, and the rotor magnet rotates inside the motor).

B series - internal rotor brushless motor (stator winding silicon steel sheet without slots, rotor magnet rotates inside the motor).

C series - external rotor brushless motor (the stator is a frame composed of windings and silicon steel sheets, and the rotor magnet rotates outside the motor).

For example, the C3525 12 model motor means that the outer diameter of the motor is 35mm, the length of the magnet or shell is 25mm, and 12 means that the coil winding is 12 turns.

B series motors generally have some special marks added by manufacturers, such as BL3674 8, the outer diameter of this motor is 36mm, the length of the magnet or shell is 74mm, 8 means that the coil winding is 8 turns, BL indicates the inner rotor lengthened brushless motor, if it is BH, there are two meanings, one is to represent the high-voltage brushless internal rotor motor, and the other is to represent the extended internal rotor brushless motor.

There is a standard for motor models, such as YKS5601-2 6KV 1600KW, Y is the first letter of the Chinese Pinyin of the word "different" in asynchronous, K refers to the first letter of the primary cooling medium back to the "empty" character in the air to answer the first letter of Hanyu Pinyin, and S refers to the first letter of the "water" character of the secondary cooling medium for water. 560 refers to the center height of 560mm, the 1 after 560 refers to the length of the No. 1 core (generally a center height motor usually has 3 4 different core lengths), -2 means that the motor is a 2-pole motor.

For more information, please refer to GB T 4831 "Motor Product Model Preparation Method".

GBT 10405-2001 "Nomenclature for Control Motor Models".

The meaning of the representation is some of the main parameters of the motor, based on the preferences of each engineer, he suddenly remembered a certain number or letter, then it is necessary to replace a certain meaning, look at the selection manual of each manufacturer.

In this model KK25F55TI, the first K - freezer refrigerator, the second K - ultra-thick insulation layer (usually refers to the cold room), 25 - volume**, representing 250 liters, F-zero degree preservation, the first 5 - door code, the second 5 intelligent mode, TI means domestic production.

KK22F, 218 liters.

KK25F, 250 liters.

The difference between KK28F and 280L is the volume.

IS - Single-stage single-suction centrifugal pump.

65 = inhalation.

Mouth diameter, unit: mm

40 = discharge port diameter, unit: mm

250 = nominal diameter of impeller, unit: mm

These are the main attribute parameters that describe centrifugal pumps, in fact, there are IS65-40-250 accurate writing and the last letters A, B, C, etc. For example, IS80-65-160a These word counts are represented separately.

One, two, three cuts.

65 = suction port diameter, unit: mm

40 = discharge port diameter, unit: mm

250 = nominal diameter of impeller, unit: mm

IS horizontal single-stage pumps.

65 imports. 40 exports.

250 impeller diameter.

This should be a kind of pinch check valve, X (seal) means rubber, in fact, H also means sealing material, X rubber and H alloy steel seal each other.

X stands for sealing material.

ZF manufacturer self number 300 caliber x rubber PN 10 pressure 10kg

The first H stands for slow closing, the second H stands for check valve, X stands for the sealing surface is rubber, P stands for the butterfly plate is stainless steel, and Q stands for ductile iron.

I don't know which manufacturer's valve you are talking about, but in general, many models are set by the manufacturer according to the specifications of their own products.
