Abstract
The utility model provides a kind of self-bleeding differential pressure transmitter, it is characterized in that, including differential pressure transmitter ontology, water-discharging nut, jointing, automatic exhaust steam valve on differential pressure transmitter are set, automatic exhaust steam valve is fixedly connected by the jointing with water-discharging nut.For the utility model at the water-discharging nut of differential pressure transmitter, automatic exhaust steam valve is matched in installation reducer union, and when the gas chamber for having gas to enter differential pressure transmitter, the buoy decline of exhaust valve automatically opens exhaust valve exhaust, until gas drains the closing of heel row air valve.Which solves the problems that accumulated gas in differential pressure transmitter influences flow measurement inaccuracy.
Description
Technical field
A kind of the utility model flow detection device technical field, and in particular to self-bleeding differential pressure transmitter.
Background technique
According to " the 4th part of electric power construction technical specification: Thermal Meter and control device " code requirement, using difference
When pressure type principle measures fluid flow, when pipeline is horizontally or diagonally to arrange, pressure takes source point should be in pipe level center line
Below in 45 ° of angles, the setting of differential pressure meter or transmitter, which should be lower than, takes source point.But it is lack of standardization due to being installed when engineering construction,
Often there are individual differential pressure meters or transmitter installation is higher than pressure and takes source point, this is resulted in differential pressure meter or transmitter content
It is inaccurate that easy accumulated gas makes flow measurement, and is limited by live physical condition, and it is larger that the later period rectifies and improves difficulty of construction.
Summary of the invention
The utility model provides a kind of self-bleeding differential pressure transmitter, prevents differential pressure transmitter pneumatosis from influencing flow and surveys
Amount, guarantees the accuracy of flow measurement.
The technical solution of the utility model is: a kind of self-bleeding differential pressure transmitter, including differential pressure transmitter ontology, if
Set water-discharging nut, jointing, automatic exhaust steam valve on differential pressure transmitter, the jointing by automatic exhaust steam valve with discharge water
Nut is fixedly connected.
Further, the jointing is reducer union to scheme, and major diameter one end is connected through a screw thread with water-discharging nut, small
Diameter one end is connect by screw thread with automatic exhaust steam valve.
Further, the automatic exhaust steam valve is vertically-mounted for scheme.
The utility model has the advantages that: the utility model at the water-discharging nut of differential pressure transmitter, match by installation reducer union
Automatic exhaust steam valve, when the gas chamber for having gas to enter differential pressure transmitter, the buoy decline of exhaust valve automatically opens exhaust valve exhaust,
Until gas drains the closing of heel row air valve.Which solves accumulated gas in differential pressure transmitter to influence asking for flow measurement inaccuracy
Topic.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Wherein: 1, water-discharging nut, 2, jointing, 3, automatic exhaust steam valve.
Specific embodiment
Clear and complete description is done to the utility model with reference to the accompanying drawing, so that those skilled in the art is not needing
Under conditions of making creative work, it can sufficiently implement utility model.
Specific embodiment of the present utility model is: as shown in Figure 1, a kind of self-bleeding differential pressure transmitter, including difference
Water-discharging nut 1, jointing 2, automatic exhaust steam valve 3 on differential pressure transmitter, the jointing is arranged in pressure transmitter ontology
Automatic exhaust steam valve is fixedly connected with water-discharging nut.
Further, the jointing 2 is reducer union, and major diameter one end is connected through a screw thread with water-discharging nut 1, path
One end is connect by screw thread with automatic exhaust steam valve 3.
Further, the automatic exhaust steam valve 3 is vertically-mounted.
The preferred embodiment of the utility model is described above, it should be pointed out that the utility model not office
It is limited to above-mentioned particular implementation, devices and structures not described in detail herein should be understood as with the common side in this field
Formula is practiced；Anyone skilled in the art, when not departing from utility model technical proposal scope, according to this
The technical spirit of utility model any simple modifications, equivalents, and modifications made to the above embodiment, still fall within this reality
In the range of the protection of new technique scheme.
