Abstract
Colloid formula temperature probe, that platinum resistance (7) is welded on double-sided wiring board (6), and signal wire (1) is welded on double-sided wiring board (6), simultaneously, one or more hard metal or nonmetal hard silk (5) are connected with the tail end of double-sided wiring board (6), the assembly that is had afterwards platinum resistance (7) to hold is put into the pressing mold of heat-conducting silicon rubber (4), allow afterwards heat-conducting silicon rubber (4) will be welded with the double-sided wiring board (6) of platinum resistance (7), hard metal or nonmetal wire (5), and a bit of signal wire (1) wraps, the heat-conducting silicon rubber wrapping up (4) is made column in double-sided wiring board (6) part that is welded with platinum resistance (7), and by rear end, be made with circular flange at this post.
Description
Technical field:
The invention belongs to the thermometric accessory of ultrasonic water meter and heat energy meter, relate in particular to a kind of colloid formula temperature probe.
Background technology:
At present, for the temperature probe on various ultrasonic water meters and calorimeter, great majority are all to adopt platinum resistance to be welded on double-sided wiring board, and in the circuit board after welding signal line, insert and be equipped with in advance in the stainless-steel thin-wall pipe of heat-conducting silicone grease, then the tail end of thin walled tube is adopted the way of roll extrusion between thin walled tube and signal wire, to form sealing.The temperature probe of making like this, in use can be all poor because of stainless-steel thin-wall pipe heat conductivility and heat conductivity of heat-conduction silicone grease, so longer to the response time of temperature; In addition, owing to often occurring, roll extrusion place sealing is bad, in use for some time, heat-conducting silicone grease in stainless-steel thin-wall pipe can volatilize, cause and in stainless-steel thin-wall pipe, become blank pipe or suck the situations such as water, finally cause temperature probe to produce very large error to the temperature survey of tested medium, even cause measured data to use.
The invention provides a solution, it can make temperature probe significantly diminish to the response time of surveyed medium; Meanwhile, can also make stability in use of the present invention and serviceable life greatly improve.
Summary of the invention:
The present invention is achieved in that it is that platinum resistance is welded on double-sided wiring board, and signal wire is welded on double-sided wiring board, simultaneously, one or more hard metal or nonmetal hard silk are connected with the tail end of double-sided wiring board, there is afterwards the assembly of platinum resistance end to put into the pressing mold of heat-conducting silicon rubber, allow afterwards heat-conducting silicon rubber be welded with the double-sided wiring board of platinum resistance, hard metal or nonmetal wire, and a bit of signal wire wraps, the heat-conducting silicon rubber wrapping up is made column at the Double-side line plate portion that is welded with platinum resistance, and by rear end, be made with circular flange at this post.Like this, with heat-conducting silicon rubber by platinum resistance and double-sided wiring board and a bit of signal wire pressing wrap up, be to cause electric short circuit or measurement parameter to change in order to make measured medium can not be immersed in platinum resistance and its relevant electrical connection place; On the one hand, because the heat conductivility of heat-conducting silicon rubber is fine, the temperature of tested medium is delivered in platinum resistance very soon by heat-conducting silicon rubber in addition.In the present invention, with one or more hard metal or nonmetal wire, being connected with double-sided wiring board, is in order to make up the problem that heat-conducting silicon rubber itself is softer.
During use, front end of the present invention is inserted in the temperature survey pipe of measured medium, then by gland nut and being threaded in temperature survey pipe, and make flange in the present invention and sealing surface compact and the sealing in temperature survey pipe, between heat-conducting silicon rubber flange and gland nut, place two packing rings, its objective is that gland nut can not make heat-conducting silicon rubber flange be subject to reducing its sealing property compared with large distortion in the process screwing.
Accompanying drawing explanation:
Fig. 1 is main pseudosection of the present invention
In figure: 1, signal wire; 2, gland nut; 3, packing ring; 4, heat-conducting silicon rubber; 5, hard metal or nonmetal wire; 6, double-sided wiring board; 7, platinum resistance.
Embodiment:
The present invention is achieved in that it is that platinum resistance (7) is welded on double-sided wiring board (6), and signal wire (1) is welded on double-sided wiring board (6), simultaneously, one or more hard metal or nonmetal hard silk (5) are connected with the tail end of double-sided wiring board (6), the assembly that is had afterwards platinum resistance (7) to hold is put into the pressing mold of heat-conducting silicon rubber (4), allow afterwards heat-conducting silicon rubber (4) will be welded with the double-sided wiring board (6) of platinum resistance (7), hard metal or nonmetal wire (5), and a bit of signal wire (1) wraps, the heat-conducting silicon rubber wrapping up (4) is made column in double-sided wiring board (6) part that is welded with platinum resistance (7), and by rear end, be made with circular flange at this post.Like this, with heat-conducting silicon rubber (4) by platinum resistance (7) and double-sided wiring board (6) and a bit of signal wire (1) pressing wrap up, be in order to make measured medium can not be immersed in platinum resistance (7) and its relevant electrical connection place causes electric short circuit or measurement parameter to change; On the one hand, because the heat conductivility of heat-conducting silicon rubber (4) is fine, the temperature of tested medium is delivered in platinum resistance (7) very soon by heat-conducting silicon rubber (4) in addition.In the present invention, with one or more hard metal or nonmetal wire (5), being connected with double-sided wiring board (6), is in order to make up the softer problem of heat-conducting silicon rubber (4) itself.
During use, front end of the present invention is inserted in the temperature survey pipe of measured medium, then by gland nut (2) and being threaded in temperature survey pipe, and make flange in the present invention and sealing surface compact and the sealing in temperature survey pipe, between heat-conducting silicon rubber flange and gland nut, place two packing rings (3), its objective is that gland nut (2) can not make heat-conducting silicon rubber (4) flange be subject to reducing its sealing property compared with large distortion in the process screwing.
