Q:What valve is z45w gate valve?
Z = gate valve4 = connection: flange5 = structure form: dark rod typeW = sealing surface material: same as valve bodyDetails: JB/T308-2004 valve model preparation methods
Q:What is gate valve (with force transfer joint)?
Double flange loose dowel joint is composed of telescopic joint and pipe flange, screw force transmission component, it can transfer the pressure thrust of the connecting piece (blind plate force) and error compensation line, cannot absorb axial displacement. Broad water supply, I hope to help you!
Q: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.
Q:What are the types and product categories of knife gate valves?
Types and classification of knife gate valves:PZ73H, PZ73F, PZ73Y manual knife gate valve: manual drive, clamp connections, rod parallel rigid single gate and valve seat sealing surface is made of hard alloy, Teflon or stainless steel body processing, nominal pressure.2PN10~16, the valve body material for carbon steel (PZ73H-10C/16C), stainless steel (PZ73F-10P/16P PZ73Y-10P/16P), with the function of slag gate valve.
Q:Which is the most expensive, check valve and gate valve?
In the case of DN50 Z15T-16 DN50: screw valve 46.200 thread copper bar gate valve Z15T-16 DN50 52 Z45F-16 DN50 97 flange valve flange valve rod Z44T-10 DN50 169 Z45T-116 DN50 flange valve dark bar 173 thread swing check valves DN50 52.090 thread straight type check valve DN50 57.280 flange screw check H44T DN50 129 flange valve lift check valve H41T-16 DN50 124
Q:How about the model of stainless steel gate valve?
Stainless steel gate valve is divided into 304 stainless steel gate valve, 316 stainless steel gate valve, 321 stainless steel gate valve. The expression is: Z41H-16P.
Q:What does the gate valve SZ45X-1.0 stand for?
Z- stands for gate valves, 4 for flange connections, 5 for wedge wedge single gate, X for rubber seals, and 1.0- for PN1.0MP
Q:What are the structural differences between parallel and wedge valves?
The advantages of dual gate plate is sealed and angle precision low temperature is not easy to make the wedge gate, the abrasion of the sealing surface and shim.The disadvantage is that the structure is complex, easy to stick in the dry medium, mainly the upper and lower baffles. After years of corrosion, the gate is easy to fall off. Although the single gate is sealed and angle accuracy requirements are relatively high, difficult processing and temperature change may make the gate wedge and other shortcomings, but has the advantages of simple structure, reliable use, especially to the flexible gate, can produce the micro elastic deformation to compensate for the deviation between the sealing surface angle processing, which is widely used at present.For more information about valves, please keep an eye on the valve knowledge section.
Q:Why does the fire hydrant box in the air defense area need to be added with gate valves?
Code for design of basement for civil air defence GB50038The installation and installation of the protective valve on the water supply line of the 6.2.13 air defense basement shall comply with the following requirements:OneWhen the water supply pipe from the entrance into, should be set up in the inner protective sealing door;
Q:What does gate valve Z41H-40 mean?
Z - that means gate valve (the initial letter of Zha)4---- is the connection form, which means flange connection1---- form of structure, which means Plain Bar wedge type rigid single gate valveH---- sealing surface overlaying ferrous carbide (initial letter of alloy steel He)40---- nominal pressure is 40 kg, or 4.0MPa, that is, PN10 at 250 degrees Celsius, the maximum working pressure is 40 kgThe material is cast carbon steel
