Description

Technical Field

[0001] The utility model relates to the technical field of flow meters, in particular to a flow meter fixing device. Background Art

[0002] In the industrial production fields such as chemical industry, agriculture and forestry, building materials, etc., the synthesis and preparation of products are basically involved, and usually pipelines need to be laid. In the process of product synthesis, since the product is prepared by the reaction of at least two reaction raw materials, a liquid conveying system is required. The different reaction raw materials stored in different storage tanks are sent into the reaction tank through the conveying system in a certain proportion to react and prepare the finished product. In order to facilitate the control of the feed rate of the reactant, a flow meter needs to be set in the conveying system to control the feed rate.

[0003] The existing announcement number is CN209069372U, and the name is a flow meter fixing device, which includes a flow meter, a pipeline, a screw, a positioning plate, a limit plate, a connecting rod, and a fixing plate. The inner side of the positioning plate is connected to the positioning plate groove, and the positioning plate groove positions the positioning plate so that the positioning plate is fixed horizontally relative to the pipeline. The side plate of the limit plate is inserted into the side plate groove of the limit plate. The relative distance between the upper and lower positioning plates is fixed by the symmetrically arranged limit plates to prevent the positioning plate from shaking. The fixing plate is connected to the positioning plate by bolts, and the fixing plate prevents the side plate of the limit plate from being separated from the side plate groove of the limit plate. The connecting rod passes through the symmetrical The connecting rod hole is connected to the No. 2 nut, so that the upper and lower symmetrical positioning plates are firmly connected, and the inner side of the positioning plate is tightly connected to the positioning plate groove. The screw passes through the right screw hole and the left screw hole in turn to connect the nut, so that the positioning plate is fixed relative to the flow meter flange, and then the pipeline and the flow meter flange are firmly connected. The three screws are evenly distributed on the positioning plate to fix the pipeline and the flow meter axially. The left side of the sealing ring is connected to the left sealing ring groove, and the right side of the sealing ring is connected to the right sealing ring groove. The sealing ring makes the connection between the pipeline and the flow meter have good sealing performance. This device has a good fixing effect on the flow meter and the pipeline.

[0004] However, when the above-mentioned flow meter is connected to the pipeline, a screw is fixed to the flange ring of the pipeline and the meter pipeline, and a rubber gasket is set between the flange rings of the pipeline and the meter pipeline for sealing. However, a single rubber sealing gasket cannot completely block the flange ring gap between the pipeline and the meter pipeline during high-pressure transportation, thereby affecting the tightness of the connection between the pipeline and the meter pipeline.
