What is the difference between the model z81x-16q and z81x-16c of the groove gate valve?
Not 16qIs 16p, the former body is stainless steel, and the latter body is carbon steel
What's the difference between the knife gate valve and the stop valve?
Standard light valve professionals to answer for you, gate valve refers to the closure of parts (gate) along the central line of the vertical direction of moving valve. The gate valve is mainly used for cutting in the pipeline. The valve is a valve with a very wide, cutting device general caliber DN = 50mm use it, sometimes a small diameter cutting device also use valve, gate valve has the following advantages:Fluid resistance is small.
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.

The valve safety valve check valve + + + = exposed part of a water pump adapter? Five
As everyone knows, the water pump adapter includes: gate valve, check valve, safety valve, the water outlet pipe and a combination of exposure. If it is a wall type, it should also include a decorative board. If the model is relatively simple and portable pump, pump adapter classification: SQS old ground fire pump adapter, SQD new type of pump adapter, SQB wall type water pump adapter. You can use Baidu Search: Shanghai Huanyao pump adapter

The legend of gate valve and stop 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.
