Abstract
The utility model relates to a health type ultrasonic wave liquid level switch is applicable to food medicine field, including signal joint, pillar, joint, sealing washer, probe and control circuit, the signal joint lies in the pillar top, connects to lie in the pillar bottom, and the end rotation closes and is connecting inside on the probe, and control circuit lies in inside the pillar. Connect with the probe between be equipped with the sealing washer, connect the inward pressure that produces when utilizing the screw to tighten and compress tightly the sealing washer to go up at the probe and realize reliable sealedly, avoided in traditional switch working process liquid medium to remain easily, go mouldy and result in the not thorough problem of disinfection, satisfy the food pharmaceuticals industry to the requirement of production environment to the cleanliness, reduction production preparation time, improvement production efficiency.
Description
Technical field
The utility model relates to a kind of liquid level metering device, is specifically related to a kind of hygiene-type ultrasonic liquid level switch, belongs to liquid tank packing technique field.
Background technology
The ultrasonic solution scope of application that compresses switch is very wide, is specially adapted to, than liquid great or that viscosity is large, comprise that some are as very unmanageable liquid such as freon, paint, coating and acids. In food and medicine production etc. to clean environment degree is required to very high field, traditional ultrasonic solution compresses switch due to the restriction of working method (often adopt external screw thread to be connected with other pipeline or directly will put into below liquid level with externally threaded switch), the cleaning-sterilizing that connecting portion is particularly exposed to threaded portion is often thorough not, and the clean residue not falling must pollute to the production of follow-up batch products after fermenting, going mouldy, affect the raising of product quality and production efficiency.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, the utility model provides a kind of hygiene-type ultrasonic liquid level switch, change the former traditional switch lower end screw thread that exposes into sealed screw thread, avoid the generation of threaded portion residue, greatly save the time of sterilizing operation, for safety, High-efficient Production provide powerful guarantee.
For achieving the above object, the technical solution adopted in the utility model is: a kind of hygiene-type ultrasonic liquid level switch, comprises data connector, pillar, probe and control circuit; Also comprise joint and sealing ring; Described joint and pillar lower end are threaded connection; Described sealing ring is pressed on pillar and probe by joint.
Further improved as the utility model, described joint is conical internal thread.
Further improved as the utility model, described pillar lower end is provided with the conical external screw thread mating with joint, and its length is 10mm～25mm.
Further improved as the utility model, described sealing ring material is rubber or copper, and its cross section is taper.
Further improved as the utility model, in described joint lower inner wall, be provided with boss; Described boss front end is provided with a tip configuration, and its internal diameter is slightly larger than the external diameter of probe.
Further improved as the utility model, described boss fore-end forms positiver sealing in indentation sealing circle in the time of assembling.
Further improved as the utility model, the tip configuration cross section of described boss is triangle.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The hygiene-type ultrasonic liquid level switch of the utility model scheme, by changing the former traditional switch lower end screw thread that exposes into sealed screw thread, avoid the generation of threaded portion residue, prepare only need to carry out disinfection to the switch surface of easy cleaning while production, greatly save the time of sterilizing operation, for safety, High-efficient Production provide powerful guarantee.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of hygiene-type ultrasonic liquid level switch of the present utility model;
Accompanying drawing 2 is the utility model joint partial sectional views;
In figure: 1, data connector; 2, pillar; 3, joint; 4, probe; 5, sealing ring; 6, boss.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of hygiene-type ultrasonic liquid level switch, is made up of Signal connector 1, pillar 2, joint 3, probe 4 and control circuit; Described Signal connector 1 is positioned at pillar 2 tops, and external action device or executing agency are used for exporting liquid level signal and then realize the control to liquid level; Probe 4 is positioned at pillar 2 bottoms, is used for gathering liquid level signal; Described switch also comprises joint 3 and sealing ring 5, described joint 3 be threaded connection with pillar 2 bottoms and by sealing ring 5 by being pressed on pillar 2 and probe 4; This design changes the screw thread that exposes of traditional switch pillar 2 lower ends into sealed screw thread, and when switch, liquid medium and threaded portion are isolated completely, have avoided residue generation.
As preferred version, described joint 3 adopts conical internal thread to be screwed in pillar 2 lower ends, and reach is 10mm～25mm, to meet fixing and seal request. Described pillar 2 lower ends arrange conical external screw thread and mate with joint 3 internal threads.
As preferred version, on described joint 3 lower end inwalls, be also provided with the boss 6 of tip configuration, its internal diameter is slightly less than the tapered thread external diameter of liquid-level probe 1.
As preferred version, described sealing ring 5 materials are rubber or copper, can select according to the difference of hydraulic fluid, and its cross section is taper; When joint 3 screws gradually, the tip configuration of boss 6 is gradually in indentation sealing circle 5 and then form positiver sealing; Sealing means had not only comprised axially but also had comprised radial compaction form, further improved the sealing property of switch, saved the treatment step of double thread part when clean, after only switch appearance need to being cleaned out, sterilized, can meet cleannes requirement.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation. All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
