Introduction of this Kind of control butterfly valve

control butterfly valve

Brief Introduction

This control butterfly valve is suitable on system such as petroleum, chemical industry, foodstuff, medicine, papermaking, water and electricity, shipping, plumbing, the smelting and sources of energy etc., and can be used as adjusting and daming equipmrnt on gas, liquid, semifluid as well as solid powder pipes and power lines and the container of many kinds of corrosiveness and non-corrosiveness. Especially extensively being used in  the fire protection system of high building and other pipe system which needs to show the switch state.

Feartures

1. Diversity in  size and light in weight. Easy installation and mintenance.  This control butterfly valve can be

mounted wherever needed.

2. Simple and compact construction,quick 90 degrees on-off operation.

3. Miniminzed operating torque, energy saving.

4. Flow curve tending to straight line. Excellent regulation performance.

5. Long service life. Standing the test of tens of thousands opening/closing perations.

6. Bubbles-tight  sealing with no leakage under the pressure test.

7. Wide selection of materials, applicable for various medium.

8. Gate valve, butterfly valve, globle valve, cock, glue pipe valve and diaphragm valve altogether, especially reaching and need show in the pipes and power lines system of valve switch state  at high layer of valve switch state at high layer of building fire protection  system, this control butterfly valve is all available.

Overall & Connection Dimensions

 Guide to control butterfly valve Selection

control butterfly valve model prepared by seven unit, its meaning is as follows: nominal pressure code of valve with Arabic numerals, its value is 10MPa pressure value for the valve of the power plant industry, mediated quality high temperature exceeds 530 centigrade, its value is 10MPa pressure valve.

Material of Main Parts

Failures that Can Occur and Methods to Eliminate

Failure Phenomenon

Sealing Surface Leakage

Reason:       1. control butterfly valve 's ring folder with debris.

                           2. pneumatic steel butterfly valve 's sealed closed position consistent errors.

                           3. Export equipped with flange bolts are uneven force or compression.

                           4. The pressure test of the control butterfly valve is incorrect.

Elimination:  1. Elimination of impurities, cleaning the control butterfly valve cavity.

                           2. Adjust the worm gear or  electric actuator, such as implementing agencies limit screw is reached the pressure                                reduce valve closed position is correct.

                           3. Check mating flange plane and bolt champing force should be evenly pressed.

                           4. Put pressure on the direction of the arrow.

control butterfly valve at Both Ends of the Surface Leak

Reason:       1. On both sides of gasket failure.

                           2. Uneven cargo pipe flange clamping force is not pressed.

Elimination:   1. Replace the gasket.

                           2. The compression flange bolts (evenly).

Method of Operation

1. control butterfly valve : handle out of the pipe into a parallel position, the pressure reduce valve in the open position,     90 centigrade angle, the valve in the closed position. Clockwise rotation of the handle is off the pressure             reduce valves, and counterclockwise rotation of the handle to open the valve.                      

2. The control butterfly valve of the worm gear: accordign to the part of the valve is installed indicating device 

    identification, clockwise rotation of the handwheel off valve counterclockwise rotation of the handwheel to open the pressure

    reduce valve.

3. Pneumatic, electric, electro-hydraulic linkage operation, in accordance with the drive manual.

Installation & Maintenance

Installation Note of the control butterfly valve

1. Prior to installation should check the control butterfly valve specifications, pressure, temperature, corrosion resistance and meet the requirements. Should check the valve's part is damaged or loose.

2. This kind of
