Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

In the first embodiment, with reference to all the drawings, a novel pressure transmitter with good stability comprises a control main body 1, wherein a protection component is arranged on the outer side of the control main body 1, the protection component comprises an outer protective shell 2 positioned on the outer side of the control main body 1, a cover body 3 is hinged to one side of the outer protective shell 2, the outer protective shell 2 and the cover body 3 are both transparent, so that the reading of the control main body 1 is not blocked, a rotating button 4 is rotatably arranged on the other side of the cover body 3, a limiting pin 5 is arranged on one side of the rotating button 4, a limiting seat 6 is arranged on the outer protective shell 2, a through hole 7 capable of accommodating the limiting pin 5 is arranged in the limiting seat 6, the limiting pin 5 and the through hole 7 are both arc-shaped and are in conformity with each other, and the insertion of the limiting pin 5 is facilitated; a main pipeline 8 is communicated below the control main body 1, a connecting pipe 9 is detachably arranged below the main pipeline 8, the connecting pipe 9 is connected with the main pipeline 8 through a flange 10, a convex ridge 11 is arranged on the flange 10 outside the connecting pipe 9, and a groove 12 capable of accommodating the convex ridge 11 is arranged below the flange 10 outside the main pipeline 8; lower extreme slides in the connecting pipe 9 and is equipped with branch pipe 13, be equipped with coupling assembling between branch pipe 13 and the connecting pipe 9, coupling assembling includes the cushion 14 that is equipped with in the lower extreme of connecting pipe 9, the lower extreme of connecting pipe 9 is equipped with a plurality of tightening strip 15 along week, the side that tightening strip 15 is relative all is equipped with anti-skidding line, can be more anti-skidding to the centre gripping of branch pipe 13, is difficult for the slippage, the connecting pipe 9 outside is equipped with the screw thread, connecting pipe 9 outside threaded connection has tightening nut 16, tightening nut 16 is inside and from the diameter of middle-end to lower extreme dwindles gradually, tightening nut 16 outside is equipped with anti-skidding line, is convenient for tighten up 16's rotation of nut.
