At present, the domestic method of shipment for crude oil mainly adopts pipeline heating delivery technology.Crude oil is just established a substation to carry out at interval of 40 ~ 90 km and is heated, pressurizes in Cemented filling.For reducing energy resource consumption, China's oil pipeline has all carried out state-of-the-art technology transformation and has achieved computer monitoring.In oil pipeline supervisory control system, for protection pipeline prevents Outlet pressure superelevation from causing booster, in departures and pump discharge header place, pressure switch is installed.For preventing oil transfer pump from finding time, there are also installed pressure switch entering the station on pipeline and pump intake pipeline.
In the place that some operating mode is narrow and small, pressure switch is not easy to install and use, and can not operate easily.
Summary of the invention
The technical problem to be solved in the present invention is, overcomes the above-mentioned defect that prior art exists, even if provide a kind of place narrow and small in some operating mode, is also convenient to the dual rotary digital display pressure switch of installing and using.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of dual rotary digital display pressure switch, comprises outer tube, display housing and elastomer joint, and display housing is stuck in outer tube top, and elastomer joint is stuck in outer tube bottom; Described elastomer joint periphery has the first groove, two the first steel balls are inlaid with in described first groove, outer tube has through hole, securing member is provided with in through hole on outer tube, securing member end to stretch in the first groove and is placed between two the first steel balls, and elastomer joint can be rotated between two the first steel balls; Described outer tube top is fixed with two the second steel balls, and display lower housing portion is provided with outstanding angle, and the outstanding angle end of display lower housing portion is placed between two the second steel balls, and display housing can be rotated between two the second steel balls.
Further, the angle that described two the first steel balls and the first groove center are formed is 270 °.
Further, described first steel ball is Ф 2mm steel ball.
Further, described securing member is holding screw.
Further, described outer tube top is step-like, and two the second steel balls are fixedly welded on the step surface on outer tube top.
Further, the angle that described two the second steel balls and step surface center are formed is 270 °.
Further, described second steel ball is Ф 2.5mm steel ball.
Further, the periphery of described elastomer joint also has the second groove, and the second groove is built with O type circle.
Further, the periphery of described display housing has the 3rd groove, O type circle is also housed in the 3rd groove.
Use the present invention, elastomer joint can be rotated between two the first steel balls, and display housing can rotate between two the second steel balls; Both match and can realize product and use within the scope of 360 °, ensure product can work well in the occasion of the narrow and small fitting operation inconvenience of some operating modes, display direction and easily patching operations easily can be provided, enhance the installation practicality of product.
