Product Description:

1.Technical Date:

Size: DN40-DN1200

Nominal Pressure: PN10/PN16

Operation Temperature: ≤200°C

Suitable Medium: Water,Steam.

2.Feature

This valve is a valve with special functions, has good flow characteristic, reasonable distribution of flow, implementation flow quantitatively, effectively solve the heating (air conditioning) room temperature is uneven and problems that exist in the system.

As set in the valve opening degree of instructions, opening the lock and a small valve used for flow measurement of pressure, so as long as in the selection and the user entry fitted with appropriate specifications of the balance valve, special and intelligent instrument for the disposable lock after debugging, the system of the total water flow control in a reasonable scope, thus overcome the "big flow rate, small temperature difference" unreasonable phenomenon. This product is the ideal product in the heating system, high medium temperature is 200 ℃.

Q:Signal butterfly valve installation or other valve installation
The installation of the signal valve is in accordance with GB50261-2005The 5.4.6 signal valve shall be installed on the pipe in front of the flow indicator, and shall not be less than 300mm from the flow indicator.The other valve control valve installation, specification, type and location of installation shall comply with the design requirements, the installation direction should be correct, control valve should be clean, no blockage, no leakage; the main control valve should be added headstock logo, the control valve cover shall be provided to indicate position of the mark in the position.1. The installation of the exhaust valve shall be carried out after the pressure test and the flushing of the system pipe. The exhaust valve shall be installed at the top of the water distribution dry pipe and the end of the distribution pipe, and no leakage shall be ensured.2, the valve flow direction should be consistent with the direction of flow in the water supply pipe, water inlet side of the filter is installed, and should be installed in the control valve; the adjustable valve should be installed horizontally, the valve cover should be upward; the proportional valve should be installed vertically: when the level of installation, the valve orifice hole single breath we should double down, breathing valve whose orifice should be in a horizontal position.3 other control valve should be installed to keep a certain distance, to facilitate maintenance and management, installation of multifunctional pump control valve itself with pressure gauge, pressure gauge should be installed in the adjacent parts; import should be prevented in the back before the installation or use of the filter with filter backflow preventer, backflow preventer at both ends the valve should be installed separately, and at least one end of the flexible joint should be installed;
Q:How about leaking water pipe valve?
1, if it is household valveA, the valve and pipe connections at the leakage, in the connection, do not rub tape (the best counter clockwise direction, so that when the valve is connected, the more twisted the more tight) ;B, if the valve itself in the leak, there are ways, it is necessary to open the valve, in which to add sealed or O ring, but it is recommended to replace a more convenient.2, if it is industrial valvesA, industrial valves leaking, if not the valve itself in the leak, then in the valve and pipe connections to join the sealing ring,B, if the valve itself is leaking, it is best to return to the manufacturer for maintenance, if not convenient, then only the manufacturers to come here for maintenance.
Q:What courses in the University involve valves?
Fluid mechanics, "material mechanics", "mechanical design" and other courses on the design of the valve are helpful.
Q:What's the valve specification DN20?
Valve specification DN20 is 6.The inches in the valve refer to inches, 1 inches =25.4mm, and 1 inches =7.62 cents.The corresponding relation between inch and DN and mm is:4 is divided into corresponding caliber DN15, that is, diameter 15mm;6 is divided into corresponding caliber DN20, that is, diameter 20mm;1 inches for the corresponding caliber DN25, that is, diameter 25mm;1.2 inches for the corresponding caliber DN32, that is, diameter 32mm;1.5 inches for the corresponding caliber DN40, that is, diameter 40mm;2 inches for the corresponding caliber DN50, that is, diameter 50mm;2.5 inches for the corresponding caliber DN65, that is, diameter 65mm;3 inches for the corresponding caliber DN80, that is, diameter 80mm;4 inches for the corresponding caliber DN100, that is, diameter 100mm;5 inches for the corresponding caliber DN125, that is, diameter 125mm;6 inches for the corresponding caliber DN150, that is, diameter 150mm;8 inches for the corresponding caliber DN200, that is, diameter 200mm;10 inches for the corresponding caliber DN250, that is, diameter 250mm.
Q:What do you mean by the 16 bit coding of the valve type?
What kind of coding do you mean? Valve type? Stress? Do you have these?Profit ZF43Y-250C-DN50.. Do you mean this one? ZF43Y valve type. Flat gate valve250C. Refers to the 250 pressure, C is carbon steel, DN50 refers to the caliber of the valve specificationsI hope you mean this one
Q:What is the term "Z41H-16C" on the line?
The ram of the Z41H-16C is linear with the stem, called (also known as the bar gate valve). Usually there is a trapezoidal thread on the lifter. The rotating motion is changed into a straight line through the nut at the top of the valve and the guide groove on the valve body. That is to say, the operating torque is changed into the operating thrust.
Q:Symbols for all types of valves
In addition to the throttle valve (L) valve (H) valve (U) valve (Y) of the four types of valves, the other is according to the first letter of the easy to remember the four valve but also second word the first letter and the other valve is repeated with the first letter of a very good record I was just valve knowledge I hope to help you!
Q:How to open the gas valve with drawings
1, according to the routine, now the handle position shows that the valve is open.2, if the handle rotated 90 degrees, the gas pipeline gas has no change, should be the stem slipped, can not drive the valve ball rotation. Try rotating several times. If it still doesn't work, ask a professional to check it out.
Q:What are the definitions of internal, external and leakage valves?
Outside leakage generally refers to the valve and connecting flange or threaded connection between the seal and guide...
Q:What does the 4 point valve mean?
That is not clear, American Standard or GB, or what other
