Abstract

The invention provides a digital pressure measuring device. The digital pressure measuring device comprises a pressure sensor, a pressure data processing module, a digital displaying module and a header; the pressure data processing module and the digital displaying module are mounted into the header; the pressure sensor is mounted in a connector which is connected with the lower end of the header; both the pressure sensor and the digital displaying module are connected with the pressure data processing module; an upper pipe joint which is in threaded matching with a sleeve is connected to the lower end of the connector; a lower pipe joint passes through the sleeve; a protruded step is arranged at the lower end of the sleeve; a protruded stopping shoulder is arranged at the upper end of the lower pipe joint. According to the digital pressure measuring device, the lower pipe joint is connected with a valve on a tested pipeline, then the header is adjusted to the direction convenient to view, the sleeve and the upper pipe joint are in threaded matching which enables the fastening of the sleeve, the upper pipe joint and the lower pipe joint, and therefore, the mounting of a temperature measuring device is done; the sleeve and the upper pipe joint are separated, then the lower pipe joint is dismounted, and thus the pressure measuring device can be dismounted.

Description

Digital pressure measurement mechanism
Technical field
The present invention relates to device for pressure measurement, specifically a kind of digital pressure measurement mechanism.
Background technology
In the industries such as oil, chemical industry, property, often need to carry out pressure detection to the liquid carried, gas.The basic structure of existing a kind of digital pressure measurement mechanism is: pressure data processing module, digital display module are housed in a gauge outfit, the lower end of gauge outfit is connected with pressure transducer, and pressure transducer and digital display module all connect with pressure data processing module.This device for pressure measurement is in installing and using, direct coupled between the lower end of its pressure transducer and tested pipeline, the pressure of fluid in tested pipeline can demonstrate by digital form, and can by data remote to production data center, but the shortcoming existed is: in use gauge outfit cannot regulate direction, and checking to scene makes troubles; Dismounting trouble when maintenance or replacing.
Summary of the invention
The object of the present invention is to provide a kind of digital pressure measurement mechanism, the direction of the gauge outfit of this device for pressure measurement can regulate arbitrarily, and its entirety can dismounting easily.
For achieving the above object, the present invention adopts following scheme: digital pressure measurement mechanism, it has pressure transducer, pressure data processing module, digital display module and gauge outfit, pressure data processing module, digital display module is loaded in gauge outfit, pressure transducer is loaded in the coupling head of gauge outfit lower end connection, pressure transducer and digital display module all connect with pressure data processing module, the lower end of coupling head is connected with pipe adapter on, upper pipe adapter coordinates with a casing threads, a lower pipe connection is had to pass in sleeve pipe, the lower end of sleeve pipe has outstanding step, lower pipe connection upper end has outstanding shoulder block.
From such scheme, lower pipe connection is connected with the valve on tested pipeline, then after adjusting gauge outfit to the direction being convenient to check, by the threaded engagement between sleeve pipe and upper pipe adapter, make tightening between sleeve pipe, upper pipe adapter, lower pipe connection three, the installation of this temperature measuring equipment can be completed, sleeve pipe is separated with upper pipe adapter, again lower pipe connection is pulled down, can this device for pressure measurement be pulled down.
Structure of the present invention is simple, convenient to disassembly, and the direction of gauge outfit can regulate arbitrarily easily, greatly to facilitate checking of field staff.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of the invention;
Fig. 2 is electric theory diagram of the present invention.
Embodiment
The present invention is further illustrated below in conjunction with embodiment and accompanying drawing.
See Fig. 1, Fig. 2
Digital pressure measurement mechanism provided by the invention has pressure transducer, pressure data processing module, digital display module and gauge outfit 1, pressure data processing module, digital display module is loaded in gauge outfit 1, pressure transducer is loaded in the coupling head 2 of gauge outfit lower end connection, pressure transducer and digital display module all connect with pressure data processing module, the lower end of coupling head 2 is connected with pipe adapter 3 on, upper pipe adapter 3 and sleeve pipe 4 threaded engagement, a lower pipe connection 5 is had to pass in sleeve pipe 4, the lower end of sleeve pipe 4 has outstanding step 4a, lower pipe connection 5 upper end has outstanding shoulder block 5a.
For ease of connecting, in the present embodiment, being thread connection between the lower end of coupling head 2 and upper pipe adapter 3, lower pipe connection 5 has external thread.In addition, for ensureing there is good sealing when using, the position in sleeve pipe 4 between upper pipe adapter 3 and lower pipe connection 5 is provided with O-ring seal 6.
As seen from Figure 1, lower pipe connection 5 is connected with the valve on tested pipeline, then after adjusting gauge outfit 1 to the direction being convenient to check, keep gauge outfit motionless, by the threaded engagement between sleeve pipe 4 and upper pipe adapter 3, make tightening between sleeve pipe 4, upper pipe adapter 3, lower pipe connection 5 three, the installation of this device for pressure measurement can be completed; Sleeve pipe 4 is separated with upper pipe adapter 3, then lower pipe connection 5 is pulled down, can this device for pressure measurement be pulled down.
Above-described pressure transducer, pressure data processing module and digital display module are existing product, and they are also prior art at the setting of gauge outfit or feeler lever, for this reason, pressure transducer, pressure data processing module and digital display module is not illustrated in Fig. 1.
After this device for pressure measurement is arranged on the valve on tested pipeline, the pipeline pressure Signal transmissions recorded processes to pressure data processing module by pressure transducer, data after process are transferred to digital display module by pressure data processing module again, are shown in gauge outfit by digital display module.In addition, data processing module in the present embodiment also can be able to be tool wireless transmission function for wire signal exports, and pressure signal, by data processing module, wired or wirelessly can be transferred to field instrument, data remote to measurement and control center, is realized pressure data remote monitoring by instrument; Can the information such as numerical monitor current pressure values, supply voltage, signal intensity, network connection, overload alarm in gauge outfit.
