Description
Technical field
The utility model belongs to measurement instrument technical field, is specifically related to a kind of high temperature hygiene-type pressure unit.
Background technology
Pressure unit is a kind of instrument pressure variations being converted to transmissible standard output signals, and in pharmacy, food, beverage, wine brewing etc. are produced, be usually used in measurement and the control of fluid flow pressure parameter, be a kind of important metering device.There is following technological deficiency in the pressure unit of prior art: first, the working temperature of normal pressures transmitter is generally below 85 degree, and food, medicine, and often in wine brewing application need 150 degree aseptic, elevated-temperature seal environment, in order to dispel the heat, the heat radiator (9) of prior art employing increasing heat radiation area is next empty leads heat radiation, and at special high temperature and without air flowing closed environment under, this radiating mode can not meet actual radiating requirements far away, especially the circuit component of transmitter is very easily damaged, even accidents caused, cause unnecessary loss, therefore be necessary to improve.Secondly, pressure unit interface section many employings threaded connector (10) of prior art, screw thread place easily shelters evil people and countenance evil practices, and is inconvenient to dismantle and clean, and does not meet international food medicine Health Administration standard; In addition, threaded connector (10) adopts tracting pressuring hole (11) syphon drainage, and contact area is limited, and precision is not high.
Utility model content
The technical matters that the utility model solves: provide a kind of high temperature hygiene-type pressure unit, solves existing pressure unit heat radiation is slow in pharmacy, food, beverage, wine brewing application, hot environment is easily damaged, easily shelters evil people and countenance evil practices, contact area is little, precision is not high technical matters.
The technical solution adopted in the utility model: high temperature hygiene-type pressure unit, there is housing, the adaptive cover body in described housing upper end, cover body and housing upper form the first room shape cavity I, circuit board is provided with in first room shape cavity I, described circuit board and the sensitive element be provided with below it electrically connect, and described housing lower end is fixedly connected with sleeve upper end, and its lower end is fixedly connected with flat film downhole joint; In sleeve pipe, with bottom circuit board for forming the second cavity II between separatrix and flat film downhole joint, described second cavity II fills thermal grease.
Preferably, described cover body has the radiating surface of multiple evagination, and is flexibly connected with between housing.
The utility model advantage compared with prior art:
1, there is two heat radiation function, top is by increasing the first room shape cavity I volume and leading heat radiation with the contact area in the external world is next empty, and bottom fills heat conductive silica gel to dispel the heat by giving the second cavity II, works along both lines, greatly improve the device performance under high-temperature closed environment, safe and reliable;
2, housing is flexibly connected with cover body, facilitates testing circuit element.
3, sensor interface adopts flat membrane structure to substitute conventional threads to connect, and has good antiscale property, health, easily installs, the advantage that easy to clean, contact area is large, precision is high, avoids the problem that thick liquid easily blocks tracting pressuring hole simultaneously;
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is conventional pressure structure of transmitter schematic diagram.
Embodiment
Below in conjunction with accompanying drawing 1, a kind of embodiment of the present utility model is described.
High temperature hygiene-type pressure unit, there is housing 2, the adaptive cover body 1 in described housing 2 upper end, first room shape cavity I is formed at cover body 1 and housing 2 top, and described cover body 1 is shaped with the radiating surface of multiple evagination, and be flexibly connected between cover body 1 with housing 2, testing circuit element is facilitated while dust-separation, the radiating surface of multiple evaginations that cover body 1 has, extend above circuit board 3 and increased and space outerpace heat exchange area while heat-dissipating space, help synchronous heat radiation, circuit board 3 is provided with in first room shape cavity I, described circuit board 3 and the sensitive element 4 be provided with below it electrically connect, described housing 2 lower end is fixedly connected with sleeve pipe 6 upper end, sleeve pipe 6 lower end is fixedly connected with flat film downhole joint 7, during embody rule, described flat film downhole joint 7 external adapter clip, described clip and flat film downhole joint 7 have easy installation, structural advantage easy to clean, also simple and efficient in operation, simultaneously, it is large that described flat film downhole joint 7 has contact area compared with the tracting pressuring hole 11 that conventional threads joint 10 is shaped with, the advantage that precision is high, it also avoid thick liquid in the past and easily block the problem of tracting pressuring hole 11, in sleeve pipe 6, with bottom circuit board 3 for forming the second cavity II between separatrix and flat film downhole joint 7, high temperature modification transmitter under contrast prior art, its radiating mode is mainly dispelled the heat by heat radiator 9, under the hot environment more than 85 degree, the performance of transmitter internal circuit board 3 can change thereupon, and be easily damaged, along with the further gradient of temperature rises, the limited area of dissipation of heat radiator 9 can not in time by heat conduction, absorb, diffusion, now the magnetic of magnetic device will disappear, the insulation failure of sheet capacitor, semiconductor burns, device package damages, circuit pin solder joint sealing-off, to permanent damage be there is in circuit board 3, transmitter is caused to be scrapped, increase production cost, affecting above-mentioned industry produces even accidents caused smoothly, occur for avoiding above-mentioned phenomenon, the utility model adopts thermal grease 5 to fill the second cavity II and solves, due to the thermal diffusivity that silica gel is good, heat energy major part is isolated, so the heat being delivered to upper circuit plate 3 part will greatly reduce, thus protection circuit plate 3 part is not by temperatures involved, moreover employing the utility model, the cavity volume of the first room shape cavity I coordinating top to be increased and help circuit board 3 sky further with the contact area in the external world and lead heat radiation, work along both lines, greatly improve the device performance under high-temperature closed environment, safe and reliable, during concrete making, the burnishing surface that external diameter is 50.5mm can be preferably designed to bottom housing 2, the clip of flat film downhole joint 7 adaptation 50.5, realize measure portion and be convenient to production equipment cleaning and sterilizing without dead angle, it also avoid the situation that material measured when being threaded pollutes mutually, be shaped with groove at flat film downhole joint 7 bottom junctions, groove adds sanitation-grade silica gel sealing ring, adaptive clip, makes tested material ne-leakage, guarantees sealing.
Above-described embodiment, just preferred embodiment of the present utility model, is not used for limiting the utility model practical range, therefore all equivalence changes done with content described in the utility model claim, all should be included within the utility model right.
