Preferably, the junction of the threeway adapter and the first tracheae and difference gauge is socketed with sealing rubber pad.
Preferably, the surge pipe includes pressure release pulling plug, and pressure release pulling plug runs through the outer wall of threeway adapter, and pressure release is drawn Sealing push-and-pull pad is connected on bolt.
Preferably, the pressure release pulling plug is T-type pressure release pulling plug, and external sealing shroud is nested on the outer ring of pressure release pulling plug, And external sealing shroud is located at the outside of threeway adapter.
Preferably, the elastic piece includes annular connecting plate, and elastic sheet rubber is bonded in the inner ring of connecting plate.
Compared with prior art, the beneficial effects of the present invention are: the present invention is by being provided with pipeline member and difference gauge one Bodyization design, and it is provided with elastic piece and the first tracheae, orifice plate two sides flow pressure difference leads to the deformation that elastic piece is extruded Amount is different, to make the first endotracheal air that extruding and pressure change occur, and then realizes measurement of the difference gauge to air pressure, keeps away The problem of difference gauge can not directly survey the pressure difference of liquid is exempted from, and by unitary design, external interference resistance is strong, leads to It crosses and is provided with surge pipe, the debugging of internal pressure can be carried out in such a way that push-and-pull is twitched, realizes the flat of the intratracheal pressure in two sides Weighing apparatus realizes the balance adjustment to measurement numerical value.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-4, the present invention provides a kind of technical solution: a kind of non-transformer uses integrated differential-pressure-type flow on the spot It counts, including pipeline member 1, abacus 2 is installed in the inner cavity of the pipeline member 1, the top left and right sides of the pipeline member 1 is integrated Connecting cylinder 3 is formed, the top of the connecting cylinder 3 is welded with the first tracheae 4, and the top of first tracheae 4 passes through Sealing Method Orchid is connected with threeway adapter 5, and the right side of threeway adapter 5 described in the left and right side of the left side threeway adapter 5 is equal It is connected with surge pipe 6 by sealing flange, the top of two threeway adapters 5 is connected with difference gauge 7 by sealing flange, Elastic piece 8 is separately installed at left and right sides of the inner cavity top of the pipeline member 1, and elastic piece 8 is located at connection described in adjacent side The bottom of cylinder 3.
Wherein, the junction of the threeway adapter 5 and the first tracheae 4 and difference gauge 7 is socketed with sealing rubber pad, mentions Air-tightness protection inside height, the surge pipe 6 includes pressure release pulling plug, and pressure release pulling plug runs through the outer wall of threeway adapter 5, and It is connected with sealing push-and-pull pad on pressure release pulling plug, by surge pipe 6 in the form of piston, a degree of push-and-pull can be carried out and adjust gas Pressure is balanced adjusting to the air pressure in the first tracheae 4 of difference gauge 7 and two sides to realize, the pressure release pulling plug is let out for T-type Pulling plug is pressed, and is nested with external sealing shroud on the outer ring of pressure release pulling plug, and external sealing shroud is located at the outside of threeway adapter 5, While convenient for push-and-pull pressure release pulling plug, the sealing effect to gas is further increased, the elastic piece 8 includes annular connecting plate, And it is bonded with elastic sheet rubber in the inner ring of connecting plate, under flow rate of liquid pressure, squeezing elastic piece 8, deformation occurs, and drives Pressure change occurs for the gas extrusion inside the first tracheae 4, to realize the mechanical gauge outfit of difference gauge 7 to fluid pressure differential Measurement.
Working principle: the present invention in use, first guarantees 1 inside no liquid flow of pipeline member, passes through push-and-pull after people Two surge pipes 6 realize that the air pressure inside the first tracheae 4 of two sides is consistent, i.e., differential pressure gauge returns to zero, then in use process In, by using the elastic piece 8 that easily deformation occurs, in logical liquid, pressure difference occurs for the flow velocity of 2 two sides of orifice plate, so as to two The dynamics of 8 punching press of elastic piece of side is different, so that deviation occurs in the gas compression degree in the first tracheae 4, is passing through difference The pressure change of 7 measurement gas of pressure meter, and then the pressure difference of fluid flow is obtained, by Mechanical measurement, effectively request use The consideration of electricity, is processed by integral molding, improves anti-windfall effect, and the situations such as infiltration is avoided to occur, and by being provided with tune Regulating device realizes that the error being likely to occur to long-time service is debugged, improves the service life of difference gauge 7.
