Abstract
The utility model is bright to propose a kind of anti-freeze pressure meter joint, including joint body, it is made of connection end and connection cylinder, connection end center is equipped with internal thread hole, and connection cylinder is equipped with central through hole, outer wall bottom is equipped with external screw thread, it connects and plunger is equipped in the central through hole of cylinder, form antifreeze sap cavity, inside fill anti-icing fluid, plunger outer diameter is identical with the aperture of central through hole, can be slided up and down along central through hole.The utility model injects anti-icing fluid in anti-freeze pressure meter joint, avoids supportting swollen, damage pressure gauge due to injection water freezing, volume increase.
Description
Technical field
The utility model belongs to the technical field of pressure tapping, is related to a kind of anti-freeze pressure meter joint.
Background technology
In water flooding, water injection well and waterflood-transmission line generally use Bourdon tube pressure gauge enroll every pressure
Data.Mounting means of the Bourdon tube pressure gauge on water injection well or waterflood-transmission line is short to weld a high pressure on well head or pipeline
Section, then be threadedly coupled mode and pressure gage valve, pressure tapping and pressure gauge are installed.In winter in production process, work as temperature
During less than injection water-setting point, since Bourdon tube pressure gauge is in cecum position, and under being connected with Bourdon tube pressure gauge
Injection water in portion's valve member (high pressure pipe nipple, pressure gage valve, pressure tapping) is in relative static conditions, valve member easily occurs
Injection water freezing in inside freezes and Bourdon tube pressure gauge is caused to damage.Substantial amounts of pressure gauge damage is not only caused under this reason
It is bad, cost payout is added, but also PRESSURE DATA admission can be caused inaccurate, the normal production in oil field is seriously affected, while
Increase the substantial amounts of work replaced and verify pressure gauge to front teams and groups.
The content of the invention
The technical problems to be solved in the utility model is to propose a kind of anti-freeze pressure meter joint, easily freezes medium using isolation
Mode is reduced because of injection jelly waterborne, icing, volume increase, and supports swollen, damage Bourdon tube pressure gauge.
Technical solution is used by the utility model solves its technical problem：A kind of anti-freeze pressure meter joint, including connecing
Head body, the joint body are made of connection end and connection cylinder, and the connection end center is equipped with internal thread hole, described
It connects cylinder and is equipped with central through hole, outer wall bottom is equipped with external screw thread, it is characterised in that：It is set in the central through hole of the connection cylinder
There is plunger, form antifreeze sap cavity, the anti-icing fluid intracavitary fills anti-icing fluid, the plunger outer diameter and the aperture phase of central through hole
Together, plunger can be slided up and down along central through hole.
By above-mentioned technical proposal, " O " type sealing ring is embedded on the plunger outer wall.
By above-mentioned technical proposal, inner wall of the connection cylinder close to a side of the connection end is equipped with shoulder.
The beneficial effects of the utility model are：It proposes a kind of anti-freeze pressure meter joint, solves current water injection well and water injection pipe
Bourdon tube pressure gauge technology existing defects are installed on line causes Bourdon tube pressure gauge flimsy problem when producing in winter,
In a manner that isolation easily freezes medium, anti-icing fluid is injected in anti-freeze pressure meter joint to reduce because injection water freezing, volume increase
Swollen, damage pressure gauge is supportted greatly, is ensured the record of water filling data, is greatly prolonged service life and the reduction of Bourdon tube pressure gauge
Front teams and groups replace and the workload of verification pressure gauge.
Description of the drawings
Fig. 1 is the fractionation structural representation of one embodiment of the utility model.
Fig. 2 is the sectional view of the connection cylinder of one embodiment of the utility model.
Wherein：Connection end 1 connects cylinder 2, internal thread hole 3, external screw thread 4, plunger 5, central through hole 6, the sealing of " O " type
Circle 7, shoulder 8.
Specific embodiment
To more fully understand the utility model, the utility model work is further retouched with reference to the accompanying drawings and examples
It states.
As shown in Figure 1 and Figure 2, a kind of anti-freeze pressure meter joint, including joint body, by connection end 1 and connection cylinder 2
Composition, connection end center are equipped with internal thread hole 3, and connection cylinder is equipped with central through hole 6, and outer wall bottom is equipped with external screw thread 4, connection
Plunger 5 is equipped in the central through hole of cylinder, forms antifreeze sap cavity, anti-icing fluid intracavitary fills anti-icing fluid, and plunger outer diameter is led to center
The aperture in hole is identical, and plunger can be slided up and down along central through hole." O " type sealing ring 7 is embedded on plunger outer wall, in central through hole
Wall radial seal, prevents anti-icing fluid to be lost in.
It connects inner wall of the cylinder close to a side of the connection end and is equipped with shoulder 8, in a high voltage state, shoulder pair
Plunger forms backstop, prevents plunger abjection connection cylinder.
The external screw thread of the external wall bottom of internal thread hole and connecting pole of connection end is respectively used to connection pressure gauge and pressure
Meter valve, plunger can move up and down in central through hole, and piston promotion is sealed in the anti-icing fluid in meter connector, can not using liquid
The characteristic of compression, by pressure conduction to pressure gauge, so as to measure pressure.Sealing ring is provided on piston, easy jelly can be effectively isolated
Medium and pressure gauge.During installation, first piston is shifted onto in the central through hole of connection cylinder, connection cylinder lower end and spring-tube type pressure
Anti-icing fluid is filled after power table control valve bolt, end connection pressure gauge is reconnected, anti-icing fluid is sealed.Pressure gauge is measuring
During pressure, when there is pressure in pipeline, pressure will promote the in vivo plunger of connecting pole to move upwards, incompressible using liquid
Characteristic by pressure conduction to Bourdon tube pressure gauge, measures pressure；When pressure declines in pipeline, connect the in vivo plunger of column and exist
It is moved downward under the action of pressure difference, Bourdon tube pressure gauge pressure value measures pressure so as to reduce.
