Abstract

The utility model relates to an electronic measurer for water temperature and water level, which especially belongs to the technical field of solar heat use and electronic measure. The utility model comprises a measurer body and a guide tube. The utility model is characterized in that the utility model also comprises a connecting tube, the measurer body is provided with a lug boss with screw threads, one end of the connecting tube is in screwed connection with the lug boss of the measurer body, the middle part of the connecting tube is provided with outer screw threads, the guide tube is fully positioned in the connecting tube, the end of the guide tube forms an upended U shape and the guide tube is filled with inert grease. The utility model has the advantages that because the end of the guide tube forms an upended U shape, the inert grease can not fully come out even if the inert grease is expanded, so a good water resistant function can be fulfilled, and pressure can be accurately conducted; meanwhile, water is not easy to enter to form scale deposit; the connecting tube and the measurer body are in screwed connection, so scale deposit including a small amount of scale deposit formed on the guide tube is easy to clear through easy disassembly; according to the thickness of a heat-insulating layer of the water tank, the position of the outer screw threads on the connecting tube can be determined.

Description

A kind of electronics water temperature, level measurement device

Technical field

The utility model relates to a kind of electronics water temperature, level measurement device, particularly solar thermal utilization and electronic measuring technology field.

Background technology

In the use of solar water heater, in order to accomplish round-the-clock use, solar water heater will be equipped with electric heater usually, in order to show water temperature, water consumption and the artificial or automatic Jia Shui of realization in real time, to add the break-make that electric heater is controlled in temperature control simultaneously, electronics water temperature, level measurement device and measurement mechanism normally need be installed measure water-heater water tank water level, water temperature, in Chinese patent CN 2489305Y, introduced a kind of more advanced device that water temperature, level measuring are united two into one.But in this structure, the most difficult still scaling problem of avoiding.The boss that has a hollow on its device body, by inside and outside all threaded connector boss on the device body and inner water tank are linked together again, and guide wire is positioned at outside the boss, though add an antiscale cap, inside charges into grease, but behind the grease expanded by heating, can overflow gradually, shrinking back water will enter, and forms incrustation scale gradually, make pressure transducer to use even to damage, also can't keep in repair.

The utility model content

The purpose of this utility model is a kind of electronics water temperature of design, level measurement device, and this device is difficult for scaling, and can clean the incrustation scale of guide wire at an easy rate.

The utility model comprises device body, guide wire, it is characterized in that also comprising connecting pipe, said device body has threaded boss, connecting pipe one end is to be threaded with the boss of device body, there is external thread at the middle part of connecting pipe, said guide wire all is positioned at connecting pipe, the U-shaped of the end of guide wire for standing upside down.

Fill with the inertia grease in the said guide wire.

The utility model has the advantages that: the U-shaped of the end of guide wire for standing upside down, the inertia grease had both made expansion also can all not come out, and played good impermeable role, also can accurately conducting pressure, also be difficult for water inlet simultaneously and form incrustation scale; Connecting pipe and device body can remove the removing incrustation scale at an easy rate for being threaded, and comprise a small amount of incrustation scale that forms on the guide wire; Externally threaded position can be determined according to the thickness of water tank heat-insulation layers on the connecting pipe.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

Embodiment

Fig. 1 has provided embodiment of the present utility model.1 is hollow thermometric post among the figure, the 2nd, and antiscale cap, the 3rd, connecting pipe, the 4th, O-ring seal, the 5th, device body, the 6th, O-ring seal, the 7th, U-shaped guide wire, the 8th, circuit board, the 9th, protective cover, the 10th, thermal sensing element, the 11st, pressure transducer, the 12nd, the boss of device body.

Welding one hollow thermometric post 1 on the boss 12 of device body 5, thermal sensing element 10 places hollow thermometric post, its output signal is delivered to temperature measurement signal collection and the treatment circuit on the signal deteching circuit plate 8, constitute the electronics water thermometer, device body and connector 3 and O-ring seal 4 constitute cavity, link to each other with pressure transducer 11 by U type pipe 7, the signal of pressure transducer is delivered to collection of survey water level signal and the treatment circuit on the signal deteching circuit plate 8, constitute electric water level gauge, 2 are the antiscale cap, be contained in the top of guide wire, hydraulic pressure is transmitted in the pressure transducer by U type pipe 4, for water is not directly contacted with pressure transducer, prevent corrosion, inject the inertia grease in the pressure transducer chamber and in the U type pipe 7; Connecting pipe 3 is threaded with device body boss 12, is easy to pull down the removing incrustation scale, can also protect U-shaped guide wire 7 wherein; The antiscale cap prevents that foreign material and incrustation scale from blocking the measurement pipeline, so the utility model dependable performance, and the life-span is long.

The utility model device body available copper alloy is made, owing to have thermal conductive resin, both has been beneficial to heat radiation when water temperature is very high in the water tank, is unlikely to make pressure transducer overheated, can prevent that also locking apparatus freezes when lower temperature.

The outside is threaded with body by guard shield 9, seals by O-ring seal 6, makes and can not intake, holding circuit plate 8.

Claims

1, a kind of electronics water temperature, level measurement device, comprise device body, guide wire, it is characterized in that also comprising connecting pipe, said device body has threaded boss, connecting pipe one end is to be threaded with the boss of device body, there is external thread at the middle part of connecting pipe, and said guide wire all is positioned at connecting pipe, the U-shaped of the end of guide wire for standing upside down.
