Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0010] Such as figure 1 As shown, a filter device for a flowmeter of the present invention includes a liquid inlet pipe 1 and a valve core 2 communicating with the liquid inlet pipe 1, and the valve core 2 is also connected with a liquid outlet pipe 3, and its innovative points are: The liquid inlet pipe 1 has a filter screen 4 inside, and the valve core 2 has a magnetic bar 5 inside. The present invention filters larger particles in the water through a filter screen, and then absorbs metal fragments in the water by a magnetic rod, so that the water quality flowing into the flow meter is relatively clean, and the service life of the flow meter is prolonged.

[0011] Such as figure 1 As shown, the upper part of the valve core 2 has an end cover 6, and the end cover 6 is fixedly connected with the valve core 2. After the present invention has been used for a...

Abstract

The invention discloses a filtering device for a flowmeter. The device comprises a liquid inlet tube, and a valve element which communicates with the liquid inlet, wherein a liquid outlet tube further communicates with the valve element. The device is characterized in that a filter screen is arranged in the liquid inlet tube; and a magnetic bar is arranged in the valve element. The device has the characteristic of prolonging the service life of the flowmeter.

Description

technical field [0001] The invention relates to an auxiliary device for a flow meter, in particular to a filter device for a flow meter. Background technique [0002] Most of the existing flow meters are used to measure the inflow and outflow directly through the fluid. The current water quality is relatively poor, the hardness of the water is relatively high, and it is easy to form dirt, and sometimes there are some metal powders, which pose a great threat to the flow meter, and are often damaged due to water quality and have a short service life. Contents of the invention [0003] The object of the present invention is to provide a filter device for a flow meter that prolongs the service life of the flow meter. [0004] In order to achieve the above purpose, the technical solution of the present invention is: a filter device for flowmeter, including a liquid inlet pipe and a valve core connected with the liquid inlet pipe, and the valve core is also connected with a liq...
