Abstract
The utility model discloses an easy-to-monitor anti-blockage check valve. The check valve comprises a valve body, wherein a valve cavity is formed in the valve body; an access hole is formed in the lower side wall of the valve body; a sealing cover is covered on the access hole; a water inlet and a water outlet are respectively formed at the left end and the right end of the valve body; a monitoring port is formed in the side wall of the water inlet; a liquid capacity monitor is fixedly mounted at the monitoring port; a filter screen is mounted on the inner wall of the water inlet; and a magnetic bar is fixedly mounted on the inner wall of the filter screen. The easy-to-monitor anti-blockage check valve has a reasonable structural design and an excellent water-stopping effect.
Description
Technical field
The utility model relates to a kind of easy monitoring anti-blocking safety check.
Background technique
Easily the open-shut device of monitoring anti-blocking safety check is opened voluntarily or is closed by media flow and strength, easily monitors the anti-blocking safety check to prevent that valve that medium flows backwards from being named.Easily monitoring anti-blocking safety check belongs to the self-acting valve class, is mainly used on the pipeline of medium one-way flow, only allows medium to flow to a direction, to try to avert accidents.Ball-type sewage is easily monitored the anti-blocking safety check: valve body adopts the full tunnel structure, has the advantage that flow is large, resistance is little.Adopt ball to do flap, be applicable to high viscosity, industry and the domestic sewage pipe network of suspended matter are arranged.
The model utility content
The utility model provides a kind of reasonable in design, and what stagnant water effect was good can be widely used in tall building, the water supply and sewerage pipeline.
The utility model technical solution problem provides following scheme:
A kind of easy monitoring anti-blocking safety check, comprise valve body, it is characterized in that: have valve pocket in the described valve body, have access opening on the described valve body lower wall, be stamped sealing cover on the described access opening, the left side of described valve body, right two ends be respectively equipped with into, water outlet, have the monitoring mouth on the sidewall of described water intake, a described monitoring mouthful place is installed with liquid flow rate monitoring instrument, on the inwall of described water intake filtering screen is installed, be installed with bar magnet on the inwall of described filtering screen, the upper end of described valve body is provided with opening, is sealed and installed with valve gap on the described opening, has support on the valve pocket inwall of described water intake one side, be hinged with rocking bar on the described support, an end of described rocking bar is installed with flap, on the sidewall of described valve pocket left side water intake valve seat is installed, described flap is overlapped on the valve seat, is installed with balancing weight on the described flap.
Between described valve gap and the valve body seal washer is installed.
The utility model reasonable in design is furnished with pouring weight on the flap, stagnant water effect is good, can be widely used in tall building, the water supply and sewerage pipeline.
