Description
Technical field
The utility model belongs to fields of measurement, more particularly to a kind of novel spring hook gauge.
Background technology
Existing bourdon gauges, its measuring principle is：Bourdon tube one end is closed, and is freely in free state
End.Row one end is fixed on support, is openend, is thus passed through by measuring pressure.Under the effect of the pressure, the cross section of bourdon tube
The circular change of product occurence tendency, the radius of curvature increase of bourdon tube, causes the displacement of free end, this displacement with by measuring pressure phase
Correspondence, is that free end produces a torque after stress.This power makes gauge pointer deflect by machine driving, so as to measure phase
The pressure answered.In actual use, often occur causes bourdon tube to occur what explosion was hurted sb.'s feelings because input pressure is excessive
Situation, to prevent the generation of such situation, the general watchcase back side is provided with spout hole, when the emergency that bourdon tube bursts
When, internal pressure will outwardly be discharged by spout hole, prevent from causing the explosion of glass panel, while in order to prevent dust etc. from entering
Enter inside table, abrased gear, cause the decline of certainty of measurement, be also provided with plug on spout hole, but plug is not for a long time
When movable, due to the aging influence of burn into, cause to be engaged with spout hole excessively tightly, in the situation that bourdon tube bursts,
Internal pressure is not enough to wash plug open in time, leads dial plate internal pressure off, easily causes glass panel to burst and hurts sb.'s feelings；It is simultaneously existing
Gauge hand is linked to be by faller gill and needle shaft riveting in technology, and faller gill is to need spray painting or electrophoresis, and ambient influnence is very big, just
And faller gill easily falls, also faller gill is the very thin of iron sheet, easy bouncing pilotage.Aperture on needle shaft is also reamed with reamer, and angle is very
Hardly possible is held, and center connection is loosely, also easily drops.
The content of the invention
The technical problems to be solved by the invention are to overcome the deficiencies in the prior art, there is provided a kind of device, in time in detection
The change of portion's pressure, when pressure exceedes maximum range, automatically opens up pressure watch back cover spout hole, prevents pressure from can not dredge in time
The situation for causing glass panel explosion to be hurted sb.'s feelings, while being made improvements to pointer so that measurement is accurate, and concrete technical scheme is such as
Under：
A kind of novel spring hook gauge, it is characterised in that：Including preceding watchcase and rear watchcase, forward and backward watchcase passes through screw
It is fixedly connected, forward and backward watchcase junction is additionally provided with sealing gasket, preceding watchcase is provided with glass panel, and watchcase rear portion is provided with excessive
Discharge orifice, is provided with Electromagnetic Control valve on hole, enclosure interior is provided with base, and bourdon tube is provided with base, and openend passes through
The interface that base lower section is set is communicated with external fluid, is screwed on base and is provided with movement, the free end of bourdon tube
The connecting rod that is displaced through drive the sector gear on movement to rotate, sector gear drives ratcheting little gear, makes to be enclosed within little gear
Indicators turn on axle, indicates tested pressure value on limbus chi, and watchcase sides are located at dial plate maximum range lower section and set
Capacitive approach switch is equipped with, capacitive approach switch is connected in series by wire with lithium battery, electromagnetic switch respectively, works as pressure
When meter pressure exceedes maximum range continuation increase, pointer is rotated to capacitive approach switch, circuit turn-on, electromagnetic switch control
Electromagnetic Control valve is opened on spout hole, makes to be interlinked to the outside in table body；
Further, described pointer is integrally moulded pointer；
The beneficial effects of the present invention are：By being positioned proximate to switch in watchcase, when pressure gauge exceedes maximum range,
Pointer is rotated out maximum range, triggers proximity switch, and circuit turn-on, the Electromagnetic Control valve on the spout hole of watchcase rear is opened
Open so that be interlinked to the outside in table body, when pressure continues to increase, when causing spring pipe explosion, due to opening spout hole, inside pressure in advance
Power will not be excessive, so as to avoid the situation that glass panel explosion is hurted sb.'s feelings.

Specific embodiment
Below by embodiment, and with reference to accompanying drawing 1-2, the technical solution of the utility model is made more specifically
It is bright.
Whether the pressure gauge of the application detects pressure beyond pressure gage measuring range, its concrete principle using capacitance-type switch
It is：One pole plate of capacitance-type switch is its shell, and the shell is connected in measurement with manometric casing, when pointer is close to
During capacitive approach switch so that the dielectric constant of electric capacity changes, and then capacitance is caused to change so that and measurement
The circuit state of head connection also changes, and thus can control connecting or disconnecting for electromagnetic switch, capacitive approach switch point
It is not connected in series with lithium battery, electromagnetic switch by wire, when gage pressure exceedes maximum range to be continued to increase, pointer rotation
Go at capacitive approach switch, illustrate that the pressure that pressure gauge is subject to alreadys exceed its range, now bourdon tube easily occurs quick-fried
Split, by circuit turn-on, Electromagnetic Control valve is opened on electromagnetic switch control spout hole, makes to be interlinked to the outside in table body, when pressure after
During continuous increase, even if bourdon tube bursts, because the valve of spout hole is opened in advance, glass panel is not resulted in quick-fried
Split, so that the danger during reducing use；
Further, described pointer is integrally moulded pointer, and it passes through grinding tool unifies processing and make, and specification is easy to
Hold, coordinate tight with cone rod, be difficult to drop；
Above specific embodiment is only used to illustrate the technical solution of the utility model and unrestricted, although with reference to example pair
The utility model has been described in detail, it will be understood by those within the art that, can be to technology of the present utility model
Scheme is modified or equivalent, and without deviating from the spirit and scope of technical solutions of the utility model, it all should cover
In the middle of right of the present utility model.
