Abstract
The invention belongs to the field of industry, water supply and drainage and environmental protection, and discloses a pipeline liquid level sensor. The pipeline liquid level sensor comprises a pipeline, a fixed pipe, a water level indicator electric contact and a liquid level relay. The fixed pipe is in threaded connection with the wall of the pipeline. The water level indicator electric contact is vertically fixed to the fixed pipe in a threaded connection manner, one end joint of the water level indicator electric contact is connected with the liquid level relay outside the pipeline, the other end joint of the water level indicator electric contact is located in the pipeline, and the height of the water level indicator electric contact is within the range of 1/4 of the diameter of the pipeline to the diameter of the pipeline. When water still exists in the pipeline, the joint located in the pipeline is connected with the water, and due to the conductivity of the water, the liquid level sensor is powered on, and a valve is controlled to be opened. When the water level in the pipeline is reduced to be separated from water, the liquid level sensor is powered off, the valve is controlled to be closed, therefore, existence of liquid can be inducted accurately and fast, the structure is simple, and cost is low.
Description
Technical field
The present invention relates to industry, water supply and sewage and field of environment protection, be specifically related to a kind of pipeline liquid level sensor.
Background technology
The liquid of the various ways of various uses can be used in department fields such as petrochemical industry, electric power, metallurgy, urban construction, chemical industry, environmental protection
Level sensor, but liquid level sensor is mounted on tank body more, when sending liquid level induced signal, at its pipeline connected still
Retain much liquid, needs carry out measure control or accurately manipulation just there is error.
Summary of the invention
In view of the deficiencies in the prior art, the present invention proposes a set of solution, it is provided that a kind of pipeline liquid level sensor.
Technical scheme is as follows:
A kind of pipeline liquid level sensor, including pipeline, fixing pipe, water-level gauge electric contact and liquid level relay, described fixing pipe with
Being threaded on the tube wall of pipeline, described water-level gauge electric contact is vertically fixed on fixing pipe, outside one tip node is with pipeline
Liquid level relay connect, other end contact is positioned at pipeline.
A kind of pipeline liquid level sensor, wherein water-level gauge electric contact is positioned at the height of a tip node of pipeline 1/4～1
In the range of pipe diameter.
A kind of pipeline liquid level sensor, the one end on pipeline connects pneumatic stopping valve.
Beneficial effects of the present invention:
Can the existence of accurate quick induced liquid, simple in construction cost is little.

Detailed description of the invention
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Embodiment 1: a kind of pipeline liquid level sensor, including pipeline, fixing pipe, water-level gauge electric contact and liquid level relay,
Fixing pipe to be threaded on the tube wall of pipeline, water-level gauge electric contact with thread connecting mode, be vertically fixed on fixing pipe,
One tip node with pipeline outside liquid level relay be connected, other end contact is positioned at pipeline, and height is the most straight at 1/4～1 pipeline
In the range of footpath.
When also having water in pipeline, water-level gauge electric contact is positioned at the contact of pipeline and is connected with water, due to the electric conductivity of water,
Liquid level sensor is connected, and controls valve and opens；When the water level decreasing in pipeline departs to water, and liquid level sensor disconnects, and controls
Valve closing.
Embodiment 2: a kind of pipeline liquid level sensor, including pipeline, fixing pipe, water-level gauge electric contact and liquid level relay,
Fixing pipe to be threaded on the tube wall of pipeline, water-level gauge electric contact with thread connecting mode, be vertically fixed on fixing pipe,
One tip node with pipeline outside liquid level relay be connected, other end contact is positioned at pipeline, and height is the most straight at 1/4～1 pipeline
In the range of footpath, the one end on pipeline is also associated with pneumatic stopping valve.
When also having water in pipeline, water-level gauge electric contact is positioned at the contact of pipeline and is connected with water, due to the electric conductivity of water,
