Q:The difference between the directly buried gate and the flange valve and butterfly valve
Buried gate also called buried gate valve, valve can be directly buried underground, built without manhole, reduce road excavation area; small well maintained road and beautiful room can reduce the difficulty of construction, reduce project cost. The directly buried soft sealing gate valve is divided into two types: telescopic type and fine fixing type, wherein, the telescopic type is divided into metal type and plastic type. In the process of construction, the telescopic type can be adjusted arbitrarily according to the distance between the buried depth of the valve and the ground, and the micro adjustment can be adjusted on the spot. The directly buried gate valve has the advantages of long-term use, no leakage, no maintenance, etc., and can effectively avoid other people switching the valve and stealing the manhole cover at will.Flange gate valve is connected to the flange gate valve, this connection is the most common way.
Q:The difference between butterfly valve d71x_10s and d341s-10
Before distinguishing between the two, you must first read the identification of the valve type:D stands for butterfly valves,3 means that the worm gear is connected and the drive does not indicate the handle7 and 4 indicate pipe to clamp connection, pipe flange connection, respectively1 means single eccentric, that is, the stem is not in the center of the butterfly plateThe former S indicates the material name of the valve body - plastic, X means sealing and the lining material is rubberThe latter S indicates the sealing lining material code ---- plastic, and the valve body is cast iron.10 means stress.
Q:How to use the fire butterfly valve properly?
Clamp and groove type and signal butterfly valve, the first two have what requirements of installation, the operating handle can rotate to open and close the valve installation, signal wiring, mouth down, to prevent water and caused a short circuit three line grounding and alarm line for leakage protection and monitoring of the valve open or closed, general are in line with the alarm valve or flow indicator matched with water, indicating the spacing of not less than 300mm, no other special requirements
Q:Electric butterfly valve (not take the lead) what do you mean?
Electric butterfly valve, as its name implies, consists of an electric actuator and butterfly valve, and the customer does not take the lead, that is, without the electric actuator, only the butterfly valve can be provided.
Q:Check valve; flexible joint `; installation order of electric butterfly valve
Connect the Songjiang rubber joint from the pump outlet. Check the 1 valve
Q:Fire, the signal butterfly valve flange connection or welding?
Fire signal butterfly valve is generally used to clamp type connection more, the clip type butterfly valve body is without flange, that is to say, with two flanges on the pipe, then screw the butterfly valve. Followed by the butterfly valve itself with flanges, and then the pipe flange with screws connected, this is the flange connection. Fire welding less use, pressure is not high!
Q:What does the butterfly valve D361H - 25C DN350 mean?
Welded turbine butterfly valve, hard seal, material: cast steel, pressure 25KG, caliber 350MM
Q:butterfly valves d7a1x5
D71x-1.6? Or D371X-1.6, do you need butterfly valves for production or butterfly valves? The question perplexed us all.
Q:What does the butterfly valve model d344h, d345h, d346h, d347h mean?
According to the international standard of the letters and numbers apart to explain D344H D is a unit of butterfly valve, two unit 3 is driving mode: turbine, three unit 4 connection: flange connection, four unit 4 Structure: seal type linkage, five unit H sealing material: Cr13 stainless steelD345H compare yourself to the above. Unit 5 four is a sealed, single eccentric structureD346H four unit 6 is an unsealed center vertical plateD347H four unit 7 is unsealed double eccentricIn general, there is only one difference between them: the structural form is different!
Q:Butterfly valve D71X-1.6C, DN50, there is no difference between C and no C? What do you mean by "concrete"?
The C indicates that the material is carbon steel and does not indicate cast iron (generally omitted)
