Abstract
The invention provides a kind of rock gas pneumatic ball valve switch speed control device, this 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.Suction port end of the present invention is provided with buffer substrate tablet, and feed air lift for a cache environment, reduce the opening speed of valve, air outlet remains unchanged simultaneously, and the closing velocity of pneumatic ball valve is unaffected, and technique simply, manufactures, maintenance cost is relatively low.
Description
Technical field
This practicality relates to a kind of rock gas pneumatic ball valve switch speed control 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 present invention is intended to propose a kind of rock gas pneumatic ball valve switch speed control device, cannot reduce the problem of opening speed with the pneumatic ball valve solving prior art.
For achieving the above object, technological scheme of the present invention is achieved in that
A kind of rock gas pneumatic ball valve switch speed control 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 rock gas pneumatic ball valve switch speed control device of the present invention, 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 present invention and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
A kind of rock gas pneumatic ball valve switch speed control 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 invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
