Turbine hydraulic control butterfly valve and a full range of series products
Need for the realization of the water turbine automatic control program and installation, general the full set of turbine inlet valve under the condition of complete sets of products should be composed of the following parts
 

1. before the valve spool 2. manual valve repair 3. bypass the slip joint 4. electric by-pass valve 5. the main valve  6. differential pressure controller 7. the main valve slip joint 8.exhaust valve  9.pressure gauge 10.After the valve spool 11.manhole 12.drain valve

一、Component function that

1, before and after the valve spool valve (figure 1, 10) by the inlet butterfly valve and the function of the upstream and downstream pressure steel pipe connections and two pieces of flanged short tubes, generally after the valve spool with access door and by-pass pipe exports, air valve, drain valve and differential pressure controller interface; Before the valve spool with by-pass pipe inlet interface. I plant general according to the requirement of the contract to design and provide the corresponding parts.

2, the main valve slip joint (figure 7) is suitable for work for - 10 ~ 80 ℃ temperature of the liquid pipe, the length of main effect is within a certain range can be adjusted valve and pipeline connection, is a necessary equipment of pipeline installation.

Expansion joints by the flat flange, sealing ring, clamp, and shorten the pipe and the corresponding connection of two double, nuts and other components, through the expansion of the telescopic pipe can be adjusted the largest structure size and minimum structure size of the slip joint. For the valve installation, maintenance, replacement, etc bring great convenience.

3, by-pass system (shown in figure 2, 3, 4) generally installed on the by-pass pipe, main effect is truncated or connecting medium, including manual by-pass valve and electric each a by-pass valve, the main valve opens before pressing.

4, air valve (figure 8) in the main effect is when the volute and inlet valve after pressure steel pipe water filling, discharge the air, so as not to run with the volute and steel tube within a large number of air and cause cavitation phenomenon.

5, drain valve (figure 12), can eliminate accumulated before the spiral case of water when maintenance. General drain valve gate valve, butterfly valve, ball valve.

6, differential pressure controller (figure 6) in the main effect is when the need to fill valve opens, test for a flat on the inlet valve, the downstream pressure.

7, pressure gauge (figure 9), used for observation before and after the valve pressure.

8, into the manhole (11), maintenance people can from the door to enter.
