During the use, a pressure taking head of a flow sensor is inserted into a measured pipeline, a full-pressure guide hole is opposite to the incoming flow direction of fluid, a static pressure guide hole is opposite to the outgoing flow direction of the fluid, a full-pressure guide pipe and a static pressure guide pipe are respectively connected with a stop valve, then the stop valves on the full-pressure guide pipe and the static pressure guide pipe are connected with a differential pressure transmitter through three valve groups, the differential pressure transmitter is connected with a flow integrating instrument, and finally the flow of fluid media in the pipeline can be calculated in the flow integrating instrument according to the differential pressure value of the fluid media in the pipeline.
One of the main problems with the above-mentioned prior art flow sensors is that: if the fluid medium in the pipeline is high-temperature high-pressure steam, when the three valve groups leak or the three valve groups leak with the interface of the differential pressure transmitter, the high-temperature high-pressure steam generated by leakage can not enable an operator to approach the stop valve to close the valve.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem of providing an automatic sealing flow sensor which can automatically block steam flow when a three-valve group leaks or an interface between the three-valve group and a differential pressure transmitter leaks.
In order to solve the technical problem, the automatic sealing flow sensor provided by the utility model is provided with a pressure taking head, wherein the pressure taking head is internally provided with a full-pressure channel and a static-pressure channel, the full-pressure channel is communicated with a full-pressure guide pipe, and the static-pressure channel is communicated with a static-pressure guide pipe, and the automatic sealing flow sensor is characterized in that: the full-pressure guide pipe and the static pressure guide pipe are respectively connected with a connecting block, one end of the connecting block is a valve joint, the other end of the connecting block is a pipe joint, a pressure channel communicated with the valve joint and the pipe joint is formed in the connecting block, and the full-pressure guide pipe and the static pressure guide pipe are respectively communicated with the pressure channel of the connected connecting block; a valve cavity is arranged in the pressure channel of the connecting block, the valve cavity is provided with a valve seat, a valve ball matched with the valve seat is arranged in the valve cavity, the diameter size of the valve ball is larger than the inner diameter size of the pressure channel, and the inner diameter size of the valve cavity is larger than the diameter size of the valve ball; the pressure channels at two sides of the valve cavity are communicated with a side-opening connecting channel, and the connecting body is provided with a needle valve for cutting off or conducting the side-opening connecting channel.
When the high-temperature and high-pressure steam flow in the measured pipeline is measured, the valve joints of the connecting blocks connected with the full-pressure guide pipe and the static-pressure guide pipe are respectively connected with the stop valves, then the stop valves are connected with the differential pressure transmitter through the three valve groups, the differential pressure transmitter is connected with the flow integrating instrument, the pressure taking head is vertically inserted into the measured pipeline, and finally the flow of the steam can be calculated in the flow integrating instrument according to a differential pressure signal generated by the steam in the measured pipeline. When the valve is used, the needle valve is adjusted to cut off the bypass connecting channel, when the three valve groups leak or the three valve groups leak from the interface of the differential pressure transmitter, steam pushes the valve ball to move forward to abut against the valve seat, the pressure channel is cut off, and the leakage of the steam is blocked, so that an operator can close the stop valve to overhaul the three valve groups or the three valve groups and the interface of the differential pressure transmitter; the needle valve adjust once more after the overhaul completion the needle valve switch on side opening interface channel, open the stop valve, steam enters into differential pressure transmitter through side opening interface channel, stop valve, three valves group, the valve ball breaks away from the contact with the disk seat when steam is in relative balanced state in the pressure passage of valve pocket both sides, switches on the valve pocket, can adjust the needle valve again this moment and cut off side opening interface channel. After the utility model is applied, when the three valve groups leak or the three valve groups leak from the interface of the differential pressure transmitter, the sensor of the utility model can automatically close and block the flow of steam, thereby preventing the further leakage of the steam and facilitating the overhaul operation of operators.
