Butterfly Valve

1. Brief Introduction

Soft Seal butterfly valve is my company under current domestic FGD system design products.

To meet the limestone and gypsum slurry grout corrosion, and the calve stem plate using a special corrosion-resistant alloys, high-valve seat wear rubber meet the large number of suspended particles in the liquid on the valve seat erosion. Therefore products with high wear-resistance and anti-corrosion of high. The product is designed to address user requirements, targeted and high reliability. Suitable Mediums: Lime cream, sulfur dioxide, lime slurry paste, process water and other corrosive media.

Q: What are the valves at home?: Valve used in the family is commonly used, the following are several:On the water pipe are: total table of the ball valve (32mm), in charge of the (25mm), as well as for the toilet, washbasin, water heater angle valve (20mm).Other commonly used gas pipelines, valves, pressure reducing valves and the like.

Q: What valve should be used to test the water valve?: Switch and multi way valve in the pipeline not only can flow, and flow diversion, flexible control of the medium, but also to turn off any channel to the other two channels. This kind of valve should be installed horizontally in the pipeline. Classification of ball valve: pneumatic ball valve, electric ball valve, manual ball valve.

Q: What does the valve "4" mean?: This is an inch inch size, 4 inches =1/2 = 25.4mm = 12mm

Q: What valves are needed on the construction site?: Depends on the actual size of the required diameter, how much work pressure, and then choose the right valve. Commonly used PVC, cast aluminum, cast iron; PVC cheap, commonly used in small diameter pipe, cast aluminum, cast iron is relatively expensive, high pressure.

Q: What is the choice of pneumatic valve or electric valve for ultrafiltration inlet control valve?: The difference between the three is as follows: pneumatic valve]: driven by compressed air valve. Operation principle: the pneumatic control valve is composed of actuating mechanism and regulating mechanism. The actuating mechanism is a thrust component of the regulating valve, which generates the corresponding thrust according to the pressure of the control signal, and drives the regulating mechanism to move. The valve body is the regulating component of the pneumatic control valve. It contacts the regulating medium directly and regulates the flow of the fluid. [hydraulic valve]: the use of oil and other liquid pressure driven valve. The working principle of the hydraulic valve control valve pressure control valve flow control valve control valve control valve to control the direction of hydraulic system oil flow direction or liquid flow through the valve two, the working principle of the valve core and the valve body and valve off valve two-way hydraulic lock check valve to make oil movement off or on, changing the direction of the oil flow, so as to realize the hydraulic actuator and its driving mechanism of starting and stopping or changing the direction of movement. [electric valve]: with electric actuators to control the valve, so as to achieve the valve opening and closing. The utility model can be divided into two parts, the upper part of which is an electric executor, and the lower half of which is a valve. Also called air conditioning valve. The electric valve is usually connected by the electric actuator and the valve, and it becomes an electric valve after installation and debugging. The electric valve uses the electric energy as the power to switch on the electric actuator to drive the valve and realize the valve switching and regulating action. So as to achieve the purpose of switching or regulating the pipeline medium.

Q: What kind of valve is it? How do you see the status of the switch?: Globe valve, not ball valveClockwise (Bell) needle to reduce the flow to the end of the shutdown, the counter clockwise to open. You can turn the multi circle plate will also lift up and down. The spindle, to the top is open, down to the edge off.The ball valve has a strip handle, the line is connected, and the cross is turned off

Q: What does 1/2 mean in valve specification?: 1/2 inches mean, converted to metric unit is 15mm, belong to small caliber, if the valve specifications, that is, the pipe diameter is 15

Q: Automatic exhaust valve installed in the pipe before and after the installation of other valves need to press it?: In general, the exhaust valve (large diameter) and a maintenance valve, normally open,

Q: What is a heavy body valve?: You should be asking what a heavy-duty valve is.This is only in the ordinary gate valve and cut-off valve on the distinction. Nowadays, ordinary gate valves and cut-off valves are divided into heavy-duty ones. Medium and light three kinds ~!

Q: How does the valve open?: Turn the valve counterclockwise, turn clockwise, or turn left, right and leftYou turn the valve to the left.
