Description
Technical field
The present invention relates to technical field of valve control, more particularly to a kind of Pneumatic opening device.
Background technology
In industrial production, the control for the flow of fluid requires more and more higher.It is related to all many-sides such as safety in production.
It is with high costs but existing headstock gear often all uses Electromagnetic Control technology, in the non-key link of in general often
Less than universal use；Furthermore Electromagnetic Control technology is high for electric power degree of dependence, once power breakdown or other confessions occur
The unexpected situation of electricity, just postback raw situation about failing immediately by the headstock gear of electromagnetic technique so that production cannot be effective
Ensure.But starter provides power by high-pressure air source, when occurring to power fortuitous event, the pressure of high-pressure air source can be tieed up
Longer time is held, therefore starter has significant advantage.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of Pneumatic opening device.
The present invention is achieved by the following technical solutions：A kind of Pneumatic opening device, including baffle plate, switching cylinder and height
Air pipe, the switching cylinder are connected with baffle plate, it is characterised in that：It is floating also to include air operated reversing valve, the first ball-cock assembly and second
Ball valve, the entrance of first ball-cock assembly and the second ball-cock assembly is connected by signal tracheae with high-pressure air pipe, described pneumatically to change
Connected to the fluid inlet of valve by the tracheae that works with high-pressure air pipe, two fluid issuings of air operated reversing valve are respectively with controlling gas
Two air admission holes connection of cylinder, the control cylinder is double-acting cylinder, and the outlet of the first ball-cock assembly and the second ball-cock assembly passes through
Tracheae is connected with two signal gas interfaces of air operated reversing valve respectively, the push rod of the control cylinder and the commutation hand of switching cylinder
Handle connects, and the installation site of the first ball-cock assembly is higher than the installation site of the second ball-cock assembly.
As further improvement of these options, two air filtration cores are installed on the work tracheae, described in two
Air filtration core is connected in series.
As further improvement of these options, first ball-cock assembly and the second ball-cock assembly are installed by a connecting rod
On base.
The present invention has advantages below compared with prior art：The present invention is simple in construction, using single high-pressure air source conduct
Power source and signal source, it effectively prevent and single provide signal and power using electric power or mixing uses electrical and pneumatic side
For the dependence of electric power in case；The characteristics of continuation that high-pressure air source has simultaneously, can ensure to have time enough to take emergent
Measure, the time that guarantee power supply takes measures when surprisingly occurring are abundant enough.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention.
Embodiment
Embodiments of the invention are elaborated below, the present embodiment is carried out lower premised on technical solution of the present invention
Implement, give detailed embodiment and specific operating process, but protection scope of the present invention is not limited to following implementation
Example.
As shown in figure 1, a kind of Pneumatic opening device, including baffle plate 1, switching cylinder 2 and high-pressure air pipe 6, switching cylinder 2 with
Baffle plate 1 connects, it is characterised in that：Also include air operated reversing valve 4, the first ball-cock assembly 51 and the second ball-cock assembly 52, the first ball-cock assembly
51 and second the entrance of ball-cock assembly 52 connected by tracheae 61 with high-pressure air pipe 6, the fluid inlet of air operated reversing valve 4 passes through work
Make tracheae 7 to connect with high-pressure air pipe 6, two air admission holes of two fluid issuings of air operated reversing valve 4 respectively with controlling cylinder 3 connect
Connect, control cylinder 3 is double-acting cylinder, and the outlet of the first ball-cock assembly 51 and the second ball-cock assembly 52 is by tracheae respectively with pneumatically changing
Connected to two signal gas interfaces of valve 4, the push rod of control cylinder 3 is connected with the reversing handle of switching cylinder 2, the first ball-cock assembly
51 installation site is higher than the installation site of the second ball-cock assembly 52.Baffle plate 1 can easily be realized by the push-and-pull of switching cylinder 2
Action, so as to effective controlled load case.When liquid level is higher than the trigger position of the first ball-cock assembly 51, the first ball-cock assembly 51 is connected to gas
Dynamic reversal valve 4 conveys signal gas, and air operated reversing valve 4 connects corresponding fluids outlet, control cylinder 3 generation action pull switch cylinder
2 reversing handle, the controlling baffle plate 1 of switching cylinder 2 action increase discharge, reduces liquid level, the first ball-cock assembly 51 is closed, pneumatic to turn
It is constant to valve state；When the trigger position of near second ball-cock assembly 52 of liquid level, the second ball-cock assembly 52 connects, to air operated reversing valve
4 conveying signal gas, air operated reversing valve 4 switch another fluid issuing of flow passage, control the steering of the Drawing switch cylinder 2 of cylinder 3
Valve, switching cylinder 2 drive the action of baffle plate 1 to reduce discharge, raise liquid level.Realized by above-mentioned action and keep liquid level all the time
Between trigger position in the first ball-cock assembly 51 and the second ball-cock assembly 52.It is simple and reliable for structure, rely solely on a high pressure gas
Source can be realized as above-mentioned control process.
Two air filtration cores 71 are installed on work tracheae 7, two air filtration cores 71 are connected in series.Device filter core can effectively be prevented
Only the impurity in high pressure gas enters air operated reversing valve 4, prevents that the sensitive reversing degree of air operated reversing valve 4 is impacted, so as to be effectively ensured
Liquid level is in safe altitude all the time.
First ball-cock assembly 51 and the second ball-cock assembly 52 are arranged on base 54 by a connecting rod 53.Pass through a connecting rod 53
By two ball-cock assemblys be arranged on same position on, can so ensure the first ball-cock assembly 51 and the second ball-cock assembly 52 measurement be
The liquid level of same position, prevent when liquid level relief intensity is too big while trigger two situations positioned at the ball-cock assembly of diverse location
Occur.
These are only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and
All any modification, equivalent and improvement made within principle etc., should be included in the scope of the protection.
