Description
Technical field
The present invention relates to oil fields, and in particular to prevents the fixing device of liquid level alarm compromised quality.
Background technology
Liquid level alarm is also floating-ball level switch, water level controller or liquid-level switch, and liquid level alarm refers to pass through machine
Tool formula or the method for magnetic induction carry out the alarm of water level and inspection, can simultaneously be controlled with audible-visual annunciator etc. or magnetic alarm
The equipment such as water pump start or stop, and there are many liquid level signal acquisition methods of liquid level alarm, according to different practical situations
Select different products.
Liquid level sensor is broadly divided into the liquid level alarm of cable type and the liquid level alarm of float-ball type.
1st, the principle of the liquid level alarm of cable type is encapsulated in outside closed plastics for core element by microswitch
High-low water level detection is carried out in shell, when fluid to be measured reaches operating point, high or low liquid level signal is exported, when liquid level is as low as certain
Position be output relay switching signal or directly supply electricity to alarm, so as to fulfill the warning function to liquid level.Cable
Formula liquid level alarm is not required to floating ball and tongue tube, and external without mechanical action, resistant is durable, is not afraid of floating material influence, any angle
Installation, is vertically equipped with certain anti-wave function, and this mode is more practical, resistant, long lifespan, safety.The liquid level of cable type
Alarm it there are two types of type of alarm：Ultra low water level is alarmed and surcharge water level alarm.
2nd, there are plastics and stainless steel material by the floating ball of the liquid level alarm of float-ball type, annular magnet is carried by inside
Floating ball with water level float up and down attract the magnetic reed switch that tongue tube is carried inside pole, send out switch alarm signal, can
High temperature resistant, acid-alkali-corrosive-resisting can do multiple alarm signals, 2 points of a floating ball, 2 floating balls, 4 points, 4 floating balls, 4 points
Function, pole length can do 4 meters.
Liquid level sensor is widely applied to water process, chemical industry, household electrical appliance, machinery equipment, electronics industry.In oil field
In, it needs to be monitored the liquid level of the fluid in oil tank, therefore usually carry out liquid level prison using liquid level sensor
It surveys.
Liquid level sensor is needed its being first placed in packing case, then be covered on packing case with head cover, most in transport
Head cover is fixedly connected with packing case with nail afterwards.
Although the packing case and head cover of this structure can fix liquid level sensor, step is numerous when separating head cover and packing case
It is trivial, time-consuming, need to be taken out nail with nail puller, and the nail having can flexural deformation in fixed head cover or during nail nipping,
It can not reuse, and the nail hole on packing case and head cover cannot also reuse.
Invention content
Present invention aims at providing to prevent the fixing device of liquid level alarm compromised quality, solve existing packing case and
Although head cover can fix liquid level sensor, complex steps when separating head cover and packing case, time-consuming, needs to be followed closely with nail puller
The problem of son takes out.
The present invention is achieved through the following technical solutions：
The fixing device of liquid level alarm compromised quality is prevented, including packing case, positioned at the head cover of packing case overthe openings
And several connecting shafts, the quantity mounting hole consistent with the quantity of connecting shaft is provided on the upper surface of the packing case,
The quantity matching hole consistent with installing hole number is provided in the lower performance of the head cover, is open when head cover is covered in packing case
When, mounting hole is respectively coaxial with a matching hole respectively, and in one end difference one mounting hole of each insertion of connecting shaft, connecting shaft
In other end difference one matching hole of each insertion, screens rubber ring, and same company are arranged at the both ends of connecting shaft side wall
Two rubber rings in spindle are located in mounting hole and matching hole, and be in pressured state respectively.
In use, first liquid level sensor is placed in packing case, then by each insertion one of one end of connecting shaft difference
In mounting hole, head cover is then placed on the one end of connecting shaft far from packing case, and make matching hole respectively respectively with a mounting hole
Coaxially, head cover is then pressed down on, so that in other end difference one matching hole of each insertion of connecting shaft, until the following table of head cover
Face is contacted with the upper surface of packing case.
By the present invention, so that when carrying liquid level sensor, head cover and packing case can be fixed without nail
The step of connecting, needing nail nipping when eliminating follow-up uncap, improves the convenience using packing case and head cover.
It when removing head cover, is inserted between packing case and head cover using wedge block, head cover and packing case is detached.
Further, be both provided with annular groove on the side wall of the connecting shaft, the axis of the annular groove with it is corresponding
The axis collinear of connecting shaft, the rubber ring are respectively set in respectively in an annular groove.
The slot bottom of the annular groove is arc, and on rounding off to the cell wall of annular groove.
The rubber ring is O-ring.
The setting of annular groove is convenient for replacing the rubber ring of aging.
Further, there are four the connecting shafts.
Compared with prior art, the present invention it has the following advantages and advantages：
1st, the present invention prevents the fixing device of liquid level alarm compromised quality, so that when carrying liquid level sensor, without
The step of head cover being fixedly connected with packing case using nail, needing nail nipping when eliminating follow-up uncap, improves use
The convenience of packing case and head cover；
2nd, the present invention prevents the fixing device of liquid level alarm compromised quality, and the rubber to aging is convenient in the setting of annular groove
Circle is replaced.
