Description
Technical field
The utility model is related to liquefied petroleum gas steel cylinder pipeline technical fields more particularly to a kind of cylinder water pressure experiment to note
Water pipe position detecting device.
Background technology
" the intelligent quick detection line of the rotating disc type liquefied petroleum gas steel cylinder water pressure test " model machine of my company's exploitation, 2015
Through domestic pharmaceutical industry expert appraisal be international most advanced level, domestic initiation.It is the problem of discovery in Curve guide impeller：Steel occurs once in a while
Before bottle runs to lower bottle position, the water in bottle not yet empties, and therefore, water injection pipe cannot be promoted, and at this moment turntable should stop back at once
Turn, mechanical accident otherwise can occur.
Utility model content
The purpose of the utility model is to overcome the deficiency of above-mentioned technology, and provide a kind of cylinder water pressure experiment water injection pipe position
Put detection device.
The utility model to achieve the above object, using following technical scheme：
A kind of cylinder water pressure experiment water injection pipe position detecting device, it is characterised in that：Including dead man formula travel switch, position
Detect cylinder, air operated reversing valve, pneumatic pilot-valve；Position detection cylinder is mounted on the inside of turntable, position detection cylinder and note
Water pipe lifting cylinder corresponds, and quantity is equal, and position detection cylinder is with water injection pipe lifting cylinder as the revolution of turntable is done together
Step movement；Dead man formula travel switch is installed on the ground, and installation site is in the previous station of lower bottle position；Position detection cylinder with
Water injection pipe lifting cylinder is connected in parallel in same pneumatic circuit and successively with the air operated reversing valve and pneumatic pilot-valve and is connected.
The beneficial effects of the utility model are:It compared with the prior art, is verified by field experiment, when steel cylinder is run to down
During the bottle previous station of station, since draining is not yet completed, water injection pipe does not rise, and position detection cylinder has been stirred stroke and opened
It closes, sends instruction, turntable stops immediately.So detection method and device are mounted on " intelligent rotating disc type liquefied petroleum gas steel cylinder
In the quick detection line of the water pressure test ", the normal operation of turntable has been efficiently controlled, has improved the security reliability of equipment.
Description of the drawings
Fig. 1 is the schematic diagram of the utility model；
Fig. 2 is the top view of the utility model turntable.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment of the present utility model is described in detail in preferred embodiment.
It should be noted that when element is referred to as " being fixedly arranged on " another element, it can be directly on another element
Or there may also be elements placed in the middle.When an element is considered as " connection " another element, it can be directly connected to
To another element or it may be simultaneously present centering elements.Term as used herein " vertical ", " horizontal ", " left side ",
" right side " and similar statement are for illustrative purposes only.
Unless otherwise defined, all of technologies and scientific terms used here by the article is led with belonging to the technology of the utility model
The normally understood meaning of technical staff in domain is identical.It is simply in the term used in the description of the utility model herein
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term as used herein " and/or " include
The arbitrary and all combination of one or more relevant Listed Items.The utility model is described in detail below in conjunction with the accompanying drawings
Concrete operating principle.
As depicted in figs. 1 and 2, a kind of cylinder water pressure experiment water injection pipe position detecting device, by position detection cylinder 3, is pulled out
Rod-type travel switch 2, air operated reversing valve 6 and pneumatic pilot-valve 7 form.
Position detection cylinder 3 is mounted on the inside of turntable 1, and the lifting cylinder 5 of it and water injection pipe corresponds, quantity phase
Deng position detection cylinder is with water injection pipe lifting cylinder as the revolution of turntable 1 is synchronized with the movement.Dead man formula travel switch 2 is installed
On the ground, installation site is in the previous station of lower bottle position.
Position detection cylinder 3 is connected in parallel on water injection pipe lifting cylinder 5 in same pneumatic circuit, at pneumatically commutation main valve 6
When shown position, simultaneously into two cylinder lower parts, cylinder rod rises compressed air simultaneously；When pneumatically commutation main valve 6 is first
Under the effect of pilot valve 7 during commutation, simultaneously into the lower part of two cylinders, cylinder rod stretches out compressed air simultaneously.Position detection cylinder
Synchronous operation is remained with water injection pipe lifting cylinder.In short, location status and the water filling of the cylinder rod of position detection cylinder
The location status of the cylinder rod of pipe lifting cylinder is consistent.
Before steel cylinder 8 runs to lower bottle position, if water in bottle not yet empties, water injection pipe 4 is still located in steel cylinder, and position is examined at this time
The cylinder rod for surveying cylinder 3 is in extended position, it will stir travel switch and send signal, and turntable is made to stop revolution, avoids machinery
Accident occurs.Judge to note using the cylinder rod and the signal that dead man formula travel switch relative position relation is sent of position detection cylinder
The location of water pipe, to determine whether turntable needs to stop at once.
The present apparatus possesses intelligent function, mechanical accident can occur to avoid accidental.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the scope of protection of the utility model.
