Description
Technical field
The utility model belongs to ocean mineral technologies field, and in particular to a kind of riser check-valves, more particularly to it is a kind of
The check-valves of ocean mineral riser.
Background technology
Have become the grand strategy target of world's major power with increasingly exhaustion, the ocean petroleum developing of land resource, it is real
The mineral products promotion of now efficient, low energy consumption deep-sea is of great significance.Ocean riser lower end has elevator pump, top to be linked to mineral
Collecting ship.Due to being the mixture of mineral and seawater in riser, particle size is larger, and riser diameter is be easy to cause greatly
Mineral mixed-liquor return increases the adherence pressure of elevator pump, reduces the pumping efficiency of ocean mineral.Therefore, in order to ensure not block up
The production efficiency that ocean mineral are promoted under the early period of pipe, reduces the pressure of elevator pump, (is compiled in project of national nature science fund project
Number:41372288) under subsidy, great mass of data search, field research and related experiment have been carried out to be studied, utility model
A kind of ocean mineral riser check-valves.
Utility model content
The purpose of this utility model is to provide a kind of ocean mineral riser check-valves, ensures to be promoted under the early period of not plugging
The production efficiency of ocean mineral, reduce the pressure of elevator pump and also it is simple in structure, easy to make, engineering practicability is strong.
The technical solution adopted in the utility model is：A kind of ocean mineral riser check-valves, it is by riser, intercept the puck
Head, counterweight ring, non-return valve blade, blade rotary shaft, fixed ring, stationary grizzly composition；The non-return valve blade can surround
Blade rotary shaft does 360 ° of rotations；The fixed ring and stationary grizzly and lift lever integral solder is integral.
The construction usage method of the utility model：A kind of ocean mineral riser check-valves is promoted in ocean mineral first
It before the installation of pipe check-valves, conscientiously checks whether the internals such as non-return valve insertion and non-return valve blade have dirt attachment, cleans check-valves
Blade and fixed ring and stationary grizzly；Then, check-valves is installed, check-valves installation site can be unrestricted, but is usually mounted to
It is vertical or tilt pipeline, it should be specifically noted that media flow direction, the arrow in regulation media flow direction, installation have been indicated on valve body
Shi Bixu makes medium normal flow direction indicate that direction is consistent with arrow, otherwise will block media flow, check-valves is fixed
Valve body should not be made to bear larger tensile, compressive, bending song or twisting stress afterwards；Then, riser is to pump up mineral and seawater mixed
When closing object, non-return valve blade upward sliding is rotated by 90 ° around blade rotary shaft under water pressure to bulb, blade is blocked, to
Open the channel pumped up；Finally, after pumping, due under the gravity of mixture and the gravity of counterweight ring, only
It returns valve blade to fall after rise to fixed ring and stationary grizzly, to make non-return valve blade close the channel that mineral aggregate is fallen after rise to anti-non-return
Miscarriage life.
The operation principle of the utility model is：A kind of ocean mineral riser check-valves, elevator pump pump up mineral with
When sea water mixing object, when by check-valves, blocked at bulb since the effect non-return valve blade of water pressure slides into, non-return valve disc
Piece automatically opens under effect of water pressure.After pumping hydraulic pressure is reduced to design pressure, non-return valve blade is in counterweight ring and top
At the mixture pressure lower slider to fixed ring and stationary grizzly of mineral and water, and under the action of fixed ring and stationary grizzly only
It returns valve blade to be closed automatically, avoids the reflux of top mixed liquor.
The utility model has the beneficial effects that：A kind of ocean mineral riser check-valves, can not only promote ocean mineral
Production efficiency, reduce the pressure of elevator pump, and it is simple in structure, easy to make, engineering practicability is strong.
Description of the drawings
Fig. 1 is a kind of structural map of ocean mineral riser check-valves of the utility model.
Fig. 2 is a kind of vertical view of ocean mineral riser check-valves of the utility model.
Fig. 3 is a kind of sectional view of ocean mineral riser check-valves of the utility model.
Marginal data：1- risers；2- blocks bulb；3- counterweight rings；4- non-return valve blades；5- blade rotary shafts；6- is solid
Determine ring；7- stationary grizzlies.
Specific implementation mode
The utility model is described further below in conjunction with the accompanying drawings.
As shown in Fig. 1 ~ Fig. 3, a kind of ocean mineral riser check-valves, it by riser 1, block bulb 2, counterweight ring 3,
Non-return valve blade 4, blade rotary shaft 5, fixed ring 6, stationary grizzly 7 form；The non-return valve blade 4 can surround blade and revolve
Shaft 5 does 360 ° of rotations；The fixed ring 6 and stationary grizzly 7 and lift lever integral solder are integral.
In use, first, before the installation of ocean mineral riser check-valves, conscientiously checking non-return valve insertion and non-return valve disc
Whether the internals such as piece 4 have dirt attachment, clean non-return valve blade 4 and fixed ring 6 and stationary grizzly 7；Then, check-valves is installed,
Check-valves installation site can be unrestricted, but is usually mounted to vertical or tilts pipeline, it should be specifically noted that media flow direction, valve
The arrow in regulation media flow direction has been indicated on body.Medium normal flow direction must be made to indicate direction phase with arrow when installation
Unanimously, media flow will otherwise be blocked.After fixing valve body should not bear check-valves, and larger tensile, compressive, bending are bent or distortion is answered
Power.Then, riser 1 is when pumping up mineral and sea water mixing object, and 4 upward sliding of non-return valve blade is to blocking bulb 2, leaf
Piece is rotated by 90 ° around blade rotary shaft 5 under water pressure, to open the channel pumped up；Finally, after pumping,
Since under the gravity of mixture and the gravity of counterweight ring 3, non-return valve blade 4 is fallen after rise to fixed ring 6 and stationary grizzly 7,
To make non-return valve blade 4 close the channel that mineral aggregate is fallen after rise to which anti-backflow generates.
