Description
Technical field
The present invention relates to transmitter, relate in particular to a kind of cleaning that is used for land and transferring oil under water, feed channel, isolate different fluid and coating corrosion-resistant Pigging object emitter.
Background technique
Pigging object emitter as a kind of device that is used for controlling the Pigging object emission of ball-type, column type and other structure be widely used in fluid pipelines such as transferring oil, gas cleaning, isolate different fluid and apply anticorrosion etc.Pigging object emitter is divided into single Pigging object emission and the emission of many Pigging objects, can also be divided into land emission and emission under water.
As shown in Figure 1, be used for land Pigging object emitter, comprise: quick operating valve 21, storage tube 20, diffuse valve 22, pressure gauge 23, bus emission valve 25, cross ball indicator 26, bus by-pass valve 27, transmitter by-pass valve 24, pipeline etc. for existing.
As shown in Figure 1, existing Pigging object emitter working procedure: 1, just begun transmitter and pressurizeed and be full of fluid, bus emission valve 25, bus by-pass valve 27, transmitter by-pass valve 24 are opened, and diffuse valve 22 and close; 2, close closed bus emission valve 25 and transmitter by-pass valve 24, open and diffuse valve 22, the transmitter internal pressure of releasing drops to external pressure, when 3, confirming transmitter emptying fully (container does not have interior pressure), open quick operating valve 21, spherical pig is put into transmitter and it is pushed into reducer, make it form (the X point place that closely cooperates at this place and pipeline, diffuse valve 22 and still be in opening state), correctly close the quick operating valve 21 of transmitter; 4, slowly open transmitter by-pass valve 24, purge transmitter (diffusing valve does not close for 22 this moments), close after purging finishes and diffuse valve 22; Continue to open transmitter by-pass valve 24, boost, close transmitter by-pass valve 24 after reaching certain pressure to transmitter; 5, open bus emission valve 25 earlier, open transmitter by-pass valve 24 then, prepare the emission spherical pig; 6, part is closed closed bus by-pass valve 27 to increase the fluid by transmitter by-pass valve 24, continuation pass closed bus by-pass valve 27 is launched up to spherical pig and enters main pipe, and crossed the ball indicator and detected, 7, enter main pipe when spherical pig leaves transmitter, standard-sized sheet bus by-pass valve 27.Through above-mentioned complex operations, finish cleaning, isolate different fluid and apply anticorrosion process pipeline.
Existing Pigging object emitter complex structure, complex operation.Because the valve and the instrument that connect are more, occur easily leaking, be difficult to guarantee sealing when being used for deep water, if damage, need to stop production and integral replacing.When launching under water, especially deep water emission needs to adopt the underwater robot operation, and difficulty is bigger.And the transmitter that is used for has under water also increased complicated long-range electrichydraulic control pipeline in addition, and the validity of control and the sealing of pipeline are difficult to guarantee that pigging process need stop production, and diffuse valve and pressure gauge in case damage, and are difficult to change, and can only launch the ball-type Pigging object.

The thickness of described cover plate is 1/3～1/2 of fast rotational pin length.
The lower end of described fast rotational pin is provided with and is connected with one
The shape latch.
The diameter of described fast rotational pin is greater than 20 millimeters.
The height of described standpipe is the diameter of oil transportation, feed channel.
Distance between described several key seat tapped holes is greater than the length or the diameter of Pigging object.
The invention has the beneficial effects as follows: its structure and operating process are simple, reduced quick operating valve, diffuse valve, pressure gauge and appurtenances thereof.Can carry out pipeline and clean in the production process that does not stop production, not influence ordinary production, damaging appears in parts changes conveniently, can also launch the Pigging object of ball-type, column type and other structural type; Reduced the possibility of leaking simultaneously under water, equipment cost is obviously reduced, Applicable scope comprises deep water and super deep water under water from land expanding to.
