Abstract
The utility model provides a slow change up of high -pressure natural gas pneumatic ball valve closes device, the device include air inlet, gas outlet and solenoid valve, the air inlet is all located on the solenoid valve with the gas outlet, the junction of air inlet tip and solenoid valve is equipped with the buffer substrate tablet, and the air inlet is in the same place with the solenoid valve spiro union, the buffer substrate tablet is the middle circular piece that is equipped with the through -hole. The utility model discloses the air inlet end is equipped with the buffer substrate tablet, and the feeding air stripping supplies a buffer memory environment to reduced the opening speed of valve, the gas outlet remains unchanged simultaneously, and pneumatic ball valve's the speed of closing is not influenced, and simple process moreover makes, the maintenance cost is relatively low.
Description
Technical field
This practicality relates to a kind of high-pressure natural gas pneumatic ball valve slow opening fast shutting device.
Background technique
It has been generally acknowledged that ball valve optimum directly does opening and closing and uses, pneumatic ball valve is that ball valve mixes pneumatic actuator, the execution speed of pneumatic actuator is relatively very fast, the fastest switching speed 0.05 second/time, so be usually pneumatic fast cut-off ball valve yet, to realize controlling on the spot and remote centralized control, do not need scene of going to or high-altitude and jeopardously bring Non-follow control, save manpower and time to a great extent, improve Security simultaneously.
It is tight that pneumatic ball valve only needs the operation of pneumatic actuator source of the gas 90-degree rotation and very little moment of rotation just can close.But the startup ball valve of present stage can not control opening speed, and especially ball valve is in hyperbaric environment, upstream device can be caused to receive impact and damage if opened fast, opening speed can ensure the safety of upstream device slowly.
Summary of the invention
In view of this, the utility model is intended to propose a kind of high-pressure natural gas pneumatic ball valve slow opening fast shutting device, cannot reduce the problem of opening speed with the pneumatic ball valve solving prior art.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of high-pressure natural gas pneumatic ball valve slow opening fast shutting device, device comprises suction port, air outlet and solenoid valve, described suction port and air outlet are all located on solenoid valve, the joint of described gas inlet end structure and solenoid valve is provided with buffer substrate tablet, and suction port and solenoid valve are screwed together, described buffer substrate tablet is the circular piece that centre is provided with through hole.
Further, the through hole in the middle of described buffer substrate tablet is circular, or rectangle and prismatic etc.
Further, be provided with outside thread outside described suction port, described electromagnetic valve entrance is provided with internal thread.
Further, described buffer substrate tablet radius is greater than suction port inner radius, is less than or equal to suction port outer radius.
Relative to prior art, a kind of high-pressure natural gas pneumatic ball valve slow opening fast shutting device described in the utility model, has following advantage:
Suction port end is provided with buffer substrate tablet, feeds gas and provides a cache environment, thus reduce the opening speed of valve, and air outlet remains unchanged simultaneously, and the closing velocity of pneumatic ball valve is unaffected, and technique simply, manufactures, maintenance cost is relatively low.

Embodiment
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As Figure 1-3, a kind of high-pressure natural gas pneumatic ball valve slow opening fast shutting device, device comprises suction port 1, air outlet 4 and solenoid valve 3, described suction port 1 is all located on solenoid valve 3 with air outlet 4, the joint of described suction port 1 end and solenoid valve 3 is provided with buffer substrate tablet, and suction port 1 and solenoid valve 3 are screwed together, described buffer substrate tablet 3 is the middle circular piece being provided with through hole.
Preferably, the through hole in the middle of described buffer substrate tablet 2 is circular, or rectangle, prismatic etc.
Be provided with outside thread outside described suction port 1, described solenoid valve 3 entrance is provided with internal thread.
Described buffer substrate tablet 2 radius is greater than suction port 1 inner radius, is less than or equal to suction port 1 outer radius.
Buffer substrate tablet 2 is placed in suction port 1 end, suction port 1 is by screw thread precession solenoid valve 3, and simultaneous buffering sheet 2 is stuck in the joint of suction port 1 end and solenoid valve 3, if suction pressure is 7bar, flow velocity 15.1m/s, pipe diameter 6mm, with flow 12.3nm before buffer substrate tablet 2
3/ h, when opening diameter is 2mm, with flow 1.36nm after buffer substrate tablet 2
3/ h, its time delay ratio, namely closing the ratio that needed time and opening first close needed time after opening is 9, and even former opening valve time is 1S, is so 9S with opening valve time after buffer substrate tablet 2; When opening diameter is 3mm, with flow 3.08nm after buffer substrate tablet 2
3/ h, its time delay ratio is 4, and even former opening valve time is 1S, is so 4S with opening valve time after buffer substrate tablet 2, achieves the slow opening fast shutting of pneumatic ball valve.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
