Abstract
A microporous filtering composite double-port air inlet and outlet valve is characterized in that an overflow supporting frame and a main port sealing ring are installed at an inner hole of the upper portion of a valve body through threads, a guide rod sleeve and a guide rod are installed on the inner hole of the overflow supporting frame, the lower end of the guide rod is connected with a floating ball, and a sealing valve seat is installed at the upper portion of the inner hole of the guide rod sleeve and used for being matched and sealed with a conical plug head. The guide rod sleeve is provided with a main valve flap which is matched and sealed with the main port sealing ring. The upper part of the valve body is provided with a filtering barrel cover, the upper end of the filtering barrel cover is provided with a plurality of layers of stainless steel sintering nets by adopting a spinning connection structure, one end of a communicating short wire is arranged at a connecting hole of the valve body and communicated with an inner cavity of the valve body, the communicating short wire is connected with a gauge valve through a reducing joint, and the gauge valve is connected with a pressure gauge. The advantage is, all adopt corrosion-resistant stainless steel material, and sanitary environmental protection inside and outside wall structure installs on defeated distribution water pipeline or in the booster pump room pipeline for get rid of the gas in the pipeline, prevent to influence normal water delivery because of collecting the trapped air, satisfy health, environmental protection and drinking water requirement.
Description
Technical Field
The utility model relates to a part among the water supply system, in particular to compound two mouthful of inlet and outlet valves of microfiltration.
Background
The air inlet and outlet valve is used in water conveying and distributing pipe network and secondary booster pump station water supply system, because the water conveying and distributing pipe network generally contains 2VOL% dissolved air in water, in the water conveying process, the air is continuously released in water, part of gas forms gas mass and accumulates in the highest point or local high point in the system, such as pipeline corner, steady flow tank and container top, the gas runs along with the water in the pipe network system in the form of free bubble, and can form air bag or air plug, which affects the running efficiency of the water conveying and distributing pipe network system. When the power failure and pump stop occur during the operation of the pipe network, negative pressure can occur to cause the vibration or the rupture of the pipeline. In addition, people have higher and higher requirements on domestic drinking water, the state also develops the drinking water standard, and the health quarantine department provides strict requirements on the inspection of wading products and the water supply of water transmission and distribution pipelines and secondary booster pump stations. There is therefore a need for an environmentally friendly, sanitary product to replace the existing commercial non-environmentally friendly products of perishable rusty cast iron materials, with traditional shells of large size, to improve the water delivery efficiency of the system and to save energy.
Disclosure of Invention
An object of the utility model is to solve the above-mentioned current problem that exists, provide a compound two port air inlet and outlet valve of microfiltration that occupation space is little, both environmental protection, sanitary again.
The utility model discloses a realize like this: an overflowing supporting frame is installed at the inner hole of the upper portion of the valve body through threads, a main port sealing ring is installed on the overflowing supporting frame, a guide rod sleeve is installed at the inner hole of the overflowing supporting frame, a guide rod is installed in the guide rod sleeve, a conical plug head is arranged at the upper end portion of the guide rod, the lower end of the guide rod is connected with a floating ball, and a sealing valve seat is installed at the upper portion of the inner hole of the guide rod sleeve and used for being matched and sealed. The guide rod sleeve is provided with a main valve flap which is matched and sealed with the main port sealing ring. The upper portion of valve body installation filters the bung, filter the bung upper end and adopt spinning connection structure installation multilayer stainless steel sintering net or stainless steel powder sintering cassette, intercommunication stub one end is installed and is communicated with each other with the inner chamber of valve body in the junction site of valve body, the intercommunication stub other end passes multilayer stainless steel sintering net or the mounting hole of stainless steel powder sintering cassette and connects fixedly through back of the body nut, the lower tip welding of valve body has the flange, the filter screen is installed to the mesopore of flange, the filter screen welding has the baffle, make the floater be located the baffle and float from top to bottom, intercommunication stub passes through reducing connector and connects the table valve, the table valve is connected the manometer.
The utility model has the advantages that, all adopt corrosion-resistant stainless steel, the interior outer wall structure of health environmental protection, this product is installed on defeated distribution pipeline or in the booster pump room pipeline, be used for getting rid of the gas in the pipeline, prevent to influence normal water delivery because of the collection is deposited gas, when the pipeline needs the evacuation, also can intake clean air to the pipeline internal suction, the protection pipeline is unlikely to warp because of the vacuum, owing to have multilayer stainless steel sintering net or stainless steel powder sintering filter plate, filtering capability has, satisfy the health, environmental protection and drinking water requirement, when water supply system if appear having a power failure, the time spent of pump pipeline internal water stream can appear the negative pressure, also can play the vacuum inhibition, ensure pipeline safety.
