Abstract
The utility model discloses a low temperature high pressure silent type check valve, including the check valve body, check valve body left end sets up the inlet pipe, and the right -hand member sets up the discharging pipe, the middle gas -tight silo that is, and gas -tight silo and inlet pipe and discharging pipe UNICOM set up sealed lid in the middle of the gas -tight silo top, set up the cylinder in the middle of the sealed lid bottom, and the valve clack is connected to the cylinder bottom, and the valve clack is cavity, and the bottom area is greater than the cross sectional area of inlet pipe, the inside cooling gel that sets up of valve clack, the utility model discloses a low temperature high pressure silent type check valve, the inside cooling gel that sets up of valve clack, avoid the in -process at material transport effectively, the material temperature who leads to because of the high pressure rises, when transporting the lower material of temperature simultaneously, can effectively keep and reduce material temperature, it influences the quality to avoid material temperature to rise, the valve clack bottom surface is great with the inlet pipe contact, the material is cooled down in making the inlet pipe easily, when the top temperature is low than the bottom temperature in the valve clack simultaneously, the cooling gel can be displaced from top to bottom in the valve clack, there is better cooling effect.
Description
Technical field
The utility model belongs to pipeline valve field and in particular to a kind of cryogenic high pressure Silent check valve.
Background technology
Pipeline widely, would generally arrange different in the use of transmission material on pipeline according to the difference of material
Valve, valve can play the effect adjusting mass flow, and ensure that the safety of pipeline transportation, is adjusted according to actual conditions
Length of tubing behaviour in service.
As long as check-valves uses during needing the unidirectional transport of material.High-pressure check valve in use, material
Pressure the thrust producing upwards is acted on flap, when material thrust be more than flap gravity when, valve is opened.When discharge nozzle thing
When the power that material pressure acts on flap adds that flap self gravitation acts on the power on flap more than charging pipe pressure, valve closes
Close, stop medium from flowing backwards.But easily heat up under high-pressure situations, material has rotten possibility, particularly harmful influence transports more
Dangerous.
Utility model content
For solving the above problems, the utility model discloses a kind of cryogenic high pressure Silent check valve.
A kind of cryogenic high pressure Silent check valve, including non-return valve body, non-return valve body left end arranges feed pipe, right-hand member
Setting discharge nozzle, middle is gas-tight silo, gas-tight silo and feed pipe and discharge nozzle UNICOM, and gas-tight silo crown center arranges closure,
Closure bottom middle setting cylinder, cylinder bottom connects flap, and flap is hollow, and bottom area is more than the section face of feed pipe
Long-pending, setting cooling gel inside flap.
As a kind of improvement of the present utility model, feed pipe is connected with gas-tight silo less than discharge nozzle with gas-tight silo connecting portion
Position.
As a kind of improvement of the present utility model, flap top side detachable.
As a kind of improvement of the present utility model, flap section is trapezoidal, and bottom surface cross-sectional length is longer than upper bottom surface.
The beneficial effects of the utility model are：
A kind of cryogenic high pressure Silent check valve of the present utility model, inside flap, setting cooling gel, is effectively prevented from
During material transportation, because the temperature of charge that high pressure leads to rises, simultaneously during the relatively low material of transport temperature, can effectively keep
With reduce temperature of charge, it is to avoid temperature of charge rises impact quality, and flap bottom surface contacts larger with feed pipe, easily makes feed pipe
Middle material cooling, when flap inner top temperature is low compared with bottom temp simultaneously, cooling gel can be replaced in flap up and down, has relatively
Good cooling effect.
Brief description
Fig. 1 is structural representation of the present utility model.
Reference numerals list：
1. non-return valve body, 2. feed pipe, 3. discharge nozzle, 4. gas-tight silo, 5. closure, 6. cylinder, 7. flap, 8. cool down
Gel.
Specific embodiment
With reference to the accompanying drawings and detailed description, it is further elucidated with the utility model it should be understood that following specific embodiment party
Formula is merely to illustrate the utility model rather than limits scope of the present utility model.It should be noted that making in describing below
Word "front", "rear", "left", "right", "up" and "down" refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively
Be directed towards or the direction away from particular elements geometric center.
As illustrated, a kind of cryogenic high pressure Silent check valve, including non-return valve body 1, non-return valve body 1 left end is arranged
Feed pipe 2, right-hand member arranges discharge nozzle 3, and middle is gas-tight silo 4, gas-tight silo 4 and feed pipe 2 and discharge nozzle 3 UNICOM, and gas-tight silo 4 pushes up
Portion's middle setting closure 5, closure 5 bottom middle setting cylinder 6, cylinder 6 bottom connects flap 7, and flap 7 is hollow, bottom
Portion's area is more than the area of section of feed pipe 2, the internal setting cooling gel 8 of flap 7, the internal setting cooling gel 8 of flap 7, has
Avoid to effect during material transportation, because the temperature of charge that high pressure leads to rises, simultaneously during the relatively low material of transport temperature, can
Effectively keep and reduce temperature of charge, it is to avoid temperature of charge rises impact quality.
As illustrated, feed pipe 2 and gas-tight silo 4 connecting portion are less than discharge nozzle 3 makes discharge nozzle with gas-tight silo 4 connecting portion
Material in 3 can not flow back, and during feed back in discharge nozzle 3, acts on the power on flap 7 when discharge nozzle 3 material pressure
When acting on the power on flap 7 plus flap 7 self gravitation more than feed pipe 2 pressure, valve closing, stop medium from flowing backwards.
As illustrated, flap 7 top side detachable, when cooling gel 8 is lost or temperature is too high, can with dismounting and change,
Or when non-return valve body 1 is stopped using, cooling gel 8 can be reclaimed, more environmentally-friendly, the restriction of use is reduced.
As illustrated, flap 7 section is trapezoidal, bottom surface cross-sectional length is longer than upper bottom surface, flap 7 bottom surface and feed pipe 2
Contact is larger, easily makes material cooling in feed pipe 2, when flap 7 inner top temperature is low compared with bottom temp simultaneously, cooling gel 8
Can replace up and down in flap 7, have preferable cooling effect.
Technological means disclosed in the utility model scheme is not limited only to the technological means disclosed in above-mentioned embodiment, also
Including by the formed technical scheme of above technical characteristic any combination.
