Abstract
Provided is a sensing head of the sensor able to change the vortex flow with sustaining flow, the utility model is provided with an amplifier, the lower end of the amplifier is successively provided with pillars, the pillar is provided with a sensing head and a compress flange in the inner hole, the bottom is provided with a meter body part, the pillar and the meter body part are added with a base therebetween, the base is provided with a dowel bar like a sensing head in the inner hole, one end of the dowel bar is inserted in the meter body part inner hole in stead of the sensing head, the other end inner hole of the dowel bar is inserted and connected with the sensing head, so the sensing head can indirectly measure the vortex force signal in the meter body and transmit to the amplifier. The utility model effectively solves the problem that the vortex flow of the sensor sensing head can be changed only when the measured pipe is in the status of being provided with flow and pressure.
Description
The utility model belongs to the sensing head of sensor, particularly a kind of under continuous flow the sensing head of replaceable vortex flow sensors.
But sensor at industry-wide measurement gas, liquid, steam flow, in use in case find the sensor senses head and damage, then need, promptly in the pipeline under the stress-free situation the pipeline cutout, can change, certainly will bring inconvenience and unnecessary loss to use like this.
The purpose of this utility model provides the sensing head of replaceable vortex flow sensors under a kind of continuous flow, and it has solved the sensing head problem that the replaceable vortex flow sensors of flow and pressure state below is promptly arranged in the tested pipeline effectively.
The purpose of this utility model realizes with following technical scheme: a kind of under continuous flow the sensing head of replaceable vortex flow sensors, it has amplifier, its amplifier lower end is equipped with pillar in succession, the pillar endoporus is equipped with sensing head and supported flange, table body assembly is equipped with in the bottom, it is characterized in that: between pillar and table body assembly, install pedestal additional, the transmission rod that exactly likes sensing head is housed in the pedestal endoporus, its transmission rod one end replaces sensing head to be plugged in the table body assembly endoporus, the endoporus of the drive link other end and sensing head are pegged graft, and make sensing head record the interior vortex force signal of table body indirectly and give amplifier.
Above-mentioned transmission rod is to be plugged in the table body assembly endoporus by the spacer medium film.
Above-mentioned transmission rod and sensing head can be contact, face contact or line contact.
Above-mentioned spacer medium thickness 0,2～2mm, its length 1,5～8cm.
The superiority that the utility model embodies is: (1) is simple in structure, need not stop pipeline flow, can change the sensing head of vortex flow sensors.(2) because sensing head contact medium not, the sense head of available low temperature is measured high-temperature medium.(3), carry out the instrument maintenance and can realize under the situation that requires not arrhea.
Specify the utility model below in conjunction with embodiment.
Accompanying drawing 1 structural representation of the present utility model.
As shown in the figure: between pillar 2 and table body assembly 7, install pedestal 5 additional, pedestal 5 and table body assembly 7 welding or bolted, transmission rod 6 is hermetically sealed solid weldings or hermetically sealed fastening with bolt with table body assembly 7, and sensing head 4 is that pillar 2 is used bolted with pedestal 5 with supported flange 3 and bolted.The transmission rod 6 that exactly likes sensing head is housed in pedestal 5 endoporus, and its transmission rod one end is plugged in table body assembly 7 endoporus, and the endoporus of the other end and sensing head 4 are pegged graft, and makes sensing head record the interior vortex force signal of table body indirectly and gives amplifier.Transmission rod 6 contact mediums part can be the circle shape, also can be duckbill.Vortical force in the medium is passed to the medium other end of transmission rod outward, pass on the sensing head again.Transmission rod 6 and sensing head 4 can be to contact, and also can be the contacts of face or line; Transmission rod 6 spacer medium thickness are at 0.2～2mm, and transmission rod, is decided according to the bore and the measuring media of vortex flow sensors at 1.5～8cm from film upper and lower side length.
Principle of work is: when MEDIA FLOW is crossed table body assembly 7, an end in the medium vortical force, the medium that acts on transmission rod 6 that replaces can pass to the outer end of transmission rod medium, sensing head 4 measures vortical force indirectly, measures vortical force as sensing head in medium like this.Sensing head 4 is given amplifier with the vortical force signal of surveying.In the use of sensor,, need to change sensing head 4, pillar 2 is pulled down as finding that sensing head damages, bolt with supported flange unclamps again, takes off sensing head 4, because of transmission rod 6 has barrier film, medium in the table body assembly 7 can not flow to the outside, and new sensing head 4 is changed.
This invention has solved vortex flow sensors, because of sensing head damages, need stop flow in the tested pipeline, waits under the state there not being pressures, and ability is replaceable and influence problem such as this instrument marketing thus.Be the replacing that the sensing head of vortex flow sensors can be at any time, do not influence the normal use of pipeline.
