Preferably, glue block up into cylinder type hollow glue stifled.
Preferably, the surface level at the stifled upper surface place of glue is not less than the surface level at the upper surface place of fluid sealant.
Preferably, shell is the stainless steel casing of integral type structure.
Preferably, on shell, be also provided with heat radiator.
The liquid turbine flowmeter the utility model proposes with full water proof type amplifier architecture rationally, facilitate durable, thermal diffusivity good, compared with prior art, its water resistance is greatly improved.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the front view of full water proof type amplifier for a kind of liquid turbine flowmeter that the utility model proposes.
In figure: 1, shell; 11, amplifier body; 12, glue is stifled; 2, nut; 3, magnetic induction coil; 31, connecting line; 4, fluid sealant.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, full water proof type amplifier for a kind of liquid turbine flowmeter, comprise: shell 1, nut 2, connecting line 31, magnetic induction coil 3 and amplifier body 11, magnetic induction coil 3 and amplifier body 11 are all arranged in shell 1, magnetic induction coil 3 is connected with amplifier body 11 by connecting line 31, afterbody in shell 1 is also provided with hollow glue stifled 12, the external diameter of glue stifled 12 under state of nature is greater than the internal diameter of shell 1, on the lower surface of shell 1, be provided with the through hole passing through for connecting line 31, connecting line 31 passes the through hole of glue stifled 12 and shell 1 lower surface successively, on the sidewall of the below of shell 1, be provided with the screw thread mating with nut 2, between shell 1 and nut 2, be also filled with fluid sealant 4.
Liquid turbine flowmeter is liquid environment by the environment for use of full water proof type amplifier, for making it have good water resistance, existing amplifier adopts fluid sealant to seal, but service time is long or environment temperature just changes when larger, fluid sealant expands with heat and contract with cold and causes sealing property variation, cause into water, affect signal accuracy and the stability of amplifier, even amplifier is caused to the serviceable life of corroding and then affecting amplifier.Full water proof type amplifier for the liquid turbine flowmeter the utility model proposes, at shell 1 and the interface of nut 2, be provided with double seal: one, the stifled 12 pairs of shells of glue that adopt external diameter to be greater than shell 1 internal diameter seal for the first time, its two, in shell 1 and nut 2 joints, use fluid sealants 4 again to seal.Such hermetically-sealed construction, greatly improve the water proofing property of amplifier, because the external diameter of glue stifled 12 is greater than the internal diameter of shell 1, so glue stifled 12 apply can to shell 1, extended out pressure in shell 1, impel shell 1 to be closely connected with nut 2 by fluid sealant 4, prevent the generation of drainage.
