Meet the one end of pipeline with the holding vessel body, with the other end and the takeover hookup of pipeline, with sleeve pipe and spigot joint hookup, can make the sphere of takeover one end and the circular conical surface of spigot joint port closely cooperate again, ensure sealed reliably, strengthen the hookup by the bolt with main flange and vice flange hookup, the further realization, can avoid jar body use or the hookup that causes because of the vibration in transit not hard up, eliminate and reveal hidden danger.
Description
Technical field
The utility model relates to device for pressure measurement, specifically a kind of digital pressure measurement mechanism.
Background technology
In the fields such as oil, chemical industry, transport, scientific research, often need to measure the pressure of the liquid stored or transport, gas.The basic structure of existing a kind of digital pressure measurement mechanism is: the data processor, the display module that connect are housed in a display gauge head, the bottom of gauge outfit is connected with the shell of a differential pressure pick-up, differential pressure pick-up connects with data processor, and positive pressure side, the negative pressure end of differential pressure pick-up have an interface respectively.This device for pressure measurement in installing and using, connecting pipeline on the interface at differential pressure pick-up two ends, and the tank body of pipeline with storage of liquids or gas is connected.The shortcoming that it in use exists is: 1, pipeline and interface connect inconvenience, the sealing of connection place is difficult to ensure; 2, the reliability connected is not ideal enough.
Utility model content
The purpose of this utility model is to provide a kind of wireless digital device for pressure measurement, and this device for pressure measurement connects convenient, good airproof performance with external pipeline, and the good reliability connected.
For achieving the above object, the utility model adopts following scheme: wireless digital device for pressure measurement, there is display gauge head and differential pressure pick-up, in display gauge head, data processor is housed, display module, data processor connects with display module, differential pressure pick-up connects with data processor, the outside of differential pressure pick-up is connected with display gauge head lower end, the positive pressure side of differential pressure pick-up, negative pressure end has one respectively and outstanding connects mouth, each connects mouth and is connected with a sleeve pipe by the mode of threaded engagement, one section of adapter has been stretched in each sleeve pipe, the outer end of sleeve pipe has back-up ring, the position that adapter is positioned at sleeve pipe has shoulder block, the port connecing mouth is circular conical surface, adapter is sphere with connecing mouth port one end in opposite directions, connect between the circular conical surface of mouth port and the sphere of adapter one end as being sealed and matched, connect on mouth and there is outstanding main flange, sleeve pipe has outstanding secondary flange, by bolt-connection between main flange and secondary flange.
From such scheme, during the wireless digital device for pressure measurement using the utility model to provide, the relevant position of one end of pipeline with the tank body storing liquid or gas is connected, the other end of pipeline is connected with adapter, again by sleeve pipe with connect mouth and connect, by sleeve pipe and the threaded engagement connecing mouth, the sphere taking over one end can be made to closely cooperate with the circular conical surface connecing mouth port, guarantee that sealing is reliable; And then by bolt by main flange and secondary flange connect, realize further strengthening connecting, the connection caused because of vibration in tank body use or transport can be avoided to loosen, eliminate and reveal hidden danger.After completing above-mentioned connection, can be measured by the pressure of this wireless digital device for pressure measurement to the gas in tank body or liquid.
The utility model structure is reliable, and it is in use convenient to disassembly and sealing is reliable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model one embodiment,
Fig. 2 is the A direction view of Fig. 1.
