Description
Technical Field
The utility model belongs to the technical field of the flowmeter is connected, concretely relates to sealing mechanism of flowmeter junction.
Background
Common connection methods of flowmeters include flange connection, threaded connection, wafer-type connection and clamp connection.
In modern industry, it is often necessary to measure the flow rate of a fluid to better monitor and control an industrial process, so that a flowmeter is developed, and various flow meters, a rotor flowmeter, a turbine flowmeter, an electromagnetic flowmeter, a vortex shedding flowmeter and the like are introduced in different industrial development directions. The connection mode of each flowmeter is different. According to the requirements of customers, even the same flow meter is not necessarily connected in the same way. The connection mode of the flowmeter is designed to the selection of types, the purchase and maintenance cost and the like, so the connection mode is an important ring in the use process of the flowmeter.
Common flow meter connections include:
firstly, flange connection: the connection method is most used, and the electromagnetic flowmeter, the turbine flowmeter, the Roots flowmeter and the like have the connection method, and the flanges at two ends and the flange on the pipeline are fixed by bolts.
II, threaded connection: some flow meters also adopt a threaded connection, and the connection mode is mostly used for pipe diameters smaller than DN50, and is generally applied to medical treatment and food industries.
Thirdly, oppositely clamping connection: the connection method is simple and convenient, the flange on the flowmeter is welded on the pipeline, and then the flowmeter is placed between the two flanges and fixed by threads. Many vortex street flowmeters use this connection.
Fourthly, clamp connection: the connection is selected from the pipelines with small caliber and low working pressure at present, and the flowmeter can be quickly assembled and disassembled through the connection mode, so that the daily cleaning and maintenance of the flowmeter are also convenient.
For a flowmeter manufacturer, the communication with a customer is to complete the flowmeter model selection work, and at this time, the opposite party needs what connection mode. In addition to the way the connection is made clear, it is clear how large the flange is, what the standard size of the flange is, what the thread is, whether the internal or external thread, a few inches of thread etc. The correct selection of the connection mode is a precondition for ensuring the normal use of the flowmeter.
When a flowmeter (such as a vortex shedding flowmeter) is installed, a user needs to additionally arrange a pair of standard flanges to be welded on the front pipeline and the rear pipeline. The welding of the strip flowmeter is not allowed, and the sealing gasket between the flanges can not be recessed into the pipeline during installation. Before the flowmeter is installed, dirt such as welding slag in the pipeline is strictly removed, and the dirt in the pipeline is as follows: debris, welding slag, stones, dust, etc. are recommended to be fitted upstream with an automated filter with 5 micron mesh for blocking droplets and sand. It is preferable to purge the piping with a constant diameter piping (or bypass) instead of the flow meter. To ensure that the flow meter is not damaged during use.
Several commonly used flowmeter connection modes are all deficient in tightness, and seepage conditions of different degrees can occur in the long-term use process. Meanwhile, the flange connection, the threaded connection and the wafer connection are complicated in component manufacturing and subsequent installation processes of the three connection modes.
SUMMERY OF THE UTILITY MODEL
