NZDF-drilling with a one-way valve where the Seoul-Overview:
NZDF-drilling with a one-way valve where the Seoul-oil drilling mud to control the device, it can automatic control and regulate the flow of mud pump pressure cycle. To overcome the existing drilling portfolio gate for the existence of the manual switch is difficult and wearing parts misoperation defects. NZDF spent type drilling where the Seoul-style one-way valve, easy to use, highly automated, long life, safe and reliable. National patent in 2092, is the ideal domestic drilling mud pipeline control devices.
Installation and using:
NZDF spent type drilling where the Seoul-style one-way valve with high-pressure valve components, such as high-pressure pipe sinks, using as a whole was being lifted, the whole installation method, the entire group has two input gate and a high-voltage output, a low-voltage output I, when used with the corresponding import and export pipeline to connect, balanced system as a whole, solid, you can use the seal.
1, before the use of one-way check valve is installed in Seoul and where the ring.
2, regular one-way check valve seals and found that the replacement of damaged in a timely manner.
3, flow control valve to open in a regular state to prevent the use of time not open.
Technical indicators:
