Abstract
The utility model discloses the dual bellows differential gauges that a kind of hermatic door is top suspension, including cabinet and hermatic door, it is hinged at the top of hermatic door and cabinet；And it is additionally provided between hermatic door and cabinet, the locking device for being locked at hermatic door after hermatic door is closed on cabinet.The purpose of this utility model is that: for existing dual bellows differential gauges flat-open type hermatic door there are illusive problem, the dual bellows differential gauges that a kind of hermatic door is top suspension are provided.The hermatic door of the dual bellows differential gauges is top suspension door, compared to more firm characteristic.
Description
Technical field
The utility model belongs to dual bellows differential gauges technical field.It is top suspension in particular it relates to a kind of hermatic door
Dual bellows differential gauges.
Background technique
Dual bellows differential gauges are the pressure instrumentations of pressure difference at a kind of two differences of measurement.Due to bi-bellow differential pressure
Meter has many advantages, such as that structure is simple, cheap, is widely used by industries such as petroleum, chemical industry, metallurgy, electric power and light industry,
It is most widely used in petroleum gas delivering pipe net field.Currently, dual bellows differential gauges are using cabinet and the knot of hermatic door
Structure, inside it by instrument installation, to achieve the purpose that protect instrument.The hermatic door of existing dual bellows differential gauges
For vertical hinged door.Hermatic door is mounted on the side of cabinet by hinge, constitutes the door that (left outside open or right external-open) is opened outward, and
It is fixed on another side of cabinet by locking device, closes hermatic door tight.
However, existing hermatic door can not be closed tight closely.It traces it to its cause, on the one hand, in frequent routine switch gate process
Middle locking device usually fails；On the other hand, since flat-open type hermatic door is lateral unlatching, after locking device failure, hermatic door
There is no any device that can maintain sealing.Hermatic door, which can not be closed tight, will lead to problems, firstly, in wet environments such as fields
Under, recording card is easy moisture damage deformation, can not accurately record production history.Secondly, under strong wind meteorological condition,
The recording card of box house cannot be close to panel, will also result in recording card inaccuracy.
Utility model content
The purpose of this utility model is that: for the flat-open type hermatic doors of existing dual bellows differential gauges, there are illusive
Problem provides the dual bellows differential gauges that a kind of hermatic door is top suspension.The hermatic door of the dual bellows differential gauges is top suspension
Door, compared to more firm characteristic.
To achieve the goals above, the technical solution adopted in the utility model are as follows:
A kind of hermatic door is the dual bellows differential gauges of top suspension, including cabinet and hermatic door, the top of hermatic door and cabinet
Portion is hinged；And be additionally provided between hermatic door and cabinet, for hermatic door to be locked at cabinet after hermatic door is closed
Locking device.Hermatic door is designed as top suspension by this programme, optimizes the switch direction of hermatic door, can be effectively poor to bi-bellow
The internal related delicate metering component of pressure meter, recording card are protected.And device is locked, it can achieve the mesh of dual-seal
's.Even if locking device failure or operator forget to close tight, due to the peculiar structure of top suspension hermatic door, its own self weight is
It can be achieved to be automatically closed, and then achieve the purpose that dual-seal.
Preferably, projecting top-hung window wind brace is installed between hermatic door and cabinet.It is being replaced convenient for instrument operation personnel
When recording card, the operation of hermatic door is opened.
Preferably, the periphery of hermatic door is provided with bound edge, and bound edge is enclosed in the outer of cabinet after hermatic door closing
Side.Bound edge further functions as the effect of sealing.
Preferably, hermatic door uses transparent plastics material.Instrument operating condition is observed convenient for instrument operation personnel,
Reduce the switching frequency of hermatic door.
Preferably, gasket is provided between bound edge and cabinet, gasket makes bound edge and cabinet compression fit.It is close
Packing can prevent rainwater etc. from entering in cabinet.
Preferably, gasket uses rubber material.Rubber material processing technology thereof is at low cost, and material cost
It is low, and there is preferable sealing effect.
Preferably, locking device includes the U-shaped spring leaf that side outside the enclosure is arranged, and is arranged on hermatic door
Card slot；U-shaped spring leaf is mutually matched with card slot after closing hermatic door.It is cooperated by card slot and spring leaf, makes hermatic door
It is easy to operate with cabinet automatically lock.
In conclusion by adopting the above-described technical solution, compared with the prior art, the beneficial effects of the utility model
Be: hermatic door is designed as top suspension by the utility model, optimizes the switch direction of hermatic door, can be effectively to dual bellows differential gauges
The protection of internal correlation delicate metering component, recording card.So that it is guaranteed that oil gas adopts the accuracy of defeated metering, instrument is also increased
Durability.Whether normally there is great importance to the production status and the defeated system of pipe that judge oil/gas well, is also oil/gas well
Lower step development plan establishment provides reference role.
Detailed description of the invention
Fig. 1 is the closed state structural schematic diagram of embodiment.
Fig. 2 is the open state structural schematic diagram of embodiment.
Specific embodiment
