Utility model content
The utility model proposes a kind of pressure compensation type flowmeter with defencive function, the technical matters that solving in prior art needs to stop after pressure transducer breaks down repairs or replaces pressure transducer, pressure transducer does not have defencive function.
The technical solution of the utility model is achieved in that a kind of pressure compensation type flowmeter with defencive function, the integrating meter comprising measuring tube and connected by syndeton, described syndeton comprises Connection Block integrated with measuring tube, the air chamber base be connected with Connection Block, the transitional connection pipe that is connected with air chamber base, and the outside of described Connection Block, transitional connection pipe is equipped with groups of fins; Also comprise pressure compensator, described pressure compensator comprises the pressure transducer, valve, the pulsation dampener that connect successively from top to bottom, groups of fins is provided with between described valve and pulsation dampener, described pressure transducer is also electrically connected with integrating meter, described pulsation dampener lower end be fixed in the connecting hole on measuring tube.
Wherein, also comprise the flow sensor be placed in air chamber base, the lower end of described flow sensor is provided with target bar, and the lower end of described target bar is connected with target sheet.
Particularly, the drainage face of described target sheet is inner concave arc surface, and following current face is in cone-shaped, and the lateral surface of this cone is inner concave arc surface.
Further, be also provided with the protective sleeve for the protection of flow sensor in described air chamber base.
Further, described protective sleeve adopts PEEK material to make.
Compared with prior art, the beneficial effects of the utility model are: damage if there is pressure transducer in metering process, and when continuing to flow, energy repair and replacement equally, to ensure the precision of measuring.Nor can because pressure transducer damages stop production to overhaul, it is convenient to safeguard, cost is low.Meanwhile, when high temperature gas medium is measured, can accurate pressure compensation be carried out, thus improve the measuring accuracy of flowmeter.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of utility model;
Fig. 2 is that the utility model hits the schematic cross-section of sheet.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
See Fig. 1, Fig. 2, a kind of pressure compensation type flowmeter with defencive function, the integrating meter 6 comprising measuring tube 7 and connected by syndeton, the transitional connection pipe 3 that described syndeton comprises Connection Block 3-2 integrated with measuring tube 7, the air chamber base 3-1 be connected with Connection Block 3-2, is connected with air chamber base 3-1, the outside of described Connection Block 3-2, transitional connection pipe 3 is equipped with groups of fins 4; Also comprise pressure compensator, described pressure compensator comprises the pressure transducer 1, valve 2, the pulsation dampener 5 that connect successively from top to bottom, groups of fins 4 is provided with between described valve 2 and pulsation dampener 5, described pressure transducer 1 is also electrically connected with integrating meter 6, described pulsation dampener 5 lower end be fixed in the connecting hole 8 on measuring tube 7.
The utility model adopts pipe thread to connect one group of groups of fins 4 in impact damper upper end; when measuring high-temperature medium; medium can reduce its medium temperature through set impact damper; the moment inertial impact force and damage pressure transducer 1 simultaneously also protecting sensor fluid to produce; groups of fins 4 can play thermolysis to measurement high-temperature medium simultaneously; temperature is reduced further, thus pressure transducer 1 serviceability temperature can be met.Pipe thread connected mode is adopted to be connected with the pocket valve 2 of employing equally in described groups of fins 4 upper end, pressure transducer 1 is arranged on pocket valve 2, again pressure transducer 1 signal wire is introduced in integrating meter 6, thus obtain force value and flow meter accurately and carry out pressure compensation accurately.The setting of groups of fins 4 outside Connection Block 3-2, transition Connection Block 3-2, reaches better heat isolation object, so as flowmeter be suitable for wider, the precision of metering is higher, and stability is better.
When needing repairing or change pressure transducer 1, only need valve-off 2, without the need to cutout, it is convenient to safeguard, cost is low.
Wherein, also comprise the flow sensor be placed in air chamber base 3-1, the lower end of described flow sensor is provided with target bar, and the lower end of described target bar is connected with target sheet 9.The drainage face of described target sheet 9 is inner concave arc surface, and following current face 11 is in cone-shaped, and the lateral surface of this cone is inner concave arc surface.Its fluoran stream surface 10 is plane or inner concave arc surface, can give full play to the ability that this fluoran stream surface 10 accepts fluid impingement force, and contributes to fluid dynamic energy umklappen and become static energy, be applied on the fluoran stream surface 10 of target sheet 9, form ergometry, become electric signal through sensor, demonstrate flow by calculating instrument.Again owing to adopting round and smooth mild transient mode to connect between the following current face 11 of target sheet 9 and fluoran stream surface 10, the stripping of boundary-layer can not be produced, and in pyramidal following current face 11, its cone outer surface is inclined-plane or inner concave arc surface, and cone top is hemispherical or taper, when fluid passes through following current face 11 of flow element, can not whirlpool be produced, fluid is flow through gently, target sheet 9 can be avoided to shake, flow signal stable transfer can be guaranteed, thus the degree of accuracy of measurement can be improved.Further, can also save the energy of fluid, the pressure loss is little, can reach energy-conservation object.
Further, be also provided with the protective sleeve for the protection of flow sensor in described air chamber base 3-1, make moist or damaged in collision for the protection of flow sensor.Described protective sleeve adopts PEEK material to make, and PEEK is a kind of high temperature resistant, high performance thermoplastic special engineering plastic.It has the performance such as good mechanical property and chemicals-resistant, wear-resistant, hydrolysis; Its light specific gravity, self-lubricating property is good, owing to having extraordinary processing characteristics.The physical dimension of flow sensor shell and smooth finish contribute to improving flow field characteristic, and different probe sectional dimensions can increase or reduce fluid flow area, to adapt to the demand of different flow scope.
