Abstract
The utility model provides a have inlet and outlet gas filtering capability discharge valve, the upper portion welding of casing has the connection closure plate, install the disk seat on the connection closure plate, the lid type nut is connected to the disk seat, the lever support, install sealed plug on the lever support, the lever leg joint floater, it has the valve pocket that communicates with each other with the casing to weld on the connection apron, the upper portion of casing is connected with the upper cover staving, spinning connection structure installation multilayer stainless steel sintering net is adopted to upper cover staving upper end, the intercommunication stub wire passes multilayer stainless steel sintering net and compresses tightly with being equipped with the lock nut, and connect the manometer. The vacuum pump has the advantages that when negative pressure occurs when the water supply system is powered off and water in the pump stopping pipeline is empty, the vacuum pump can play a role in vacuum inhibition, and the safety of the pipeline is ensured. The upper end of the upper cover barrel body adopts a spinning connection structure to install a plurality of layers of stainless steel sintering nets, and can effectively filter and intercept harmful gas of dust particles from entering a water delivery system, thereby avoiding the pollution to drinking water.
Description
Technical Field
The utility model relates to a part among the water supply system, in particular to have into exhaust filtering capability discharge valve.
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 in the water conveying and distributing pipe network generally contains 2VOL% dissolved air, in the water conveying and distributing process, the air is continuously released in the water, part of the air forms air mass to be accumulated at the highest point or local high point in the system, such as the corner of a pipeline, the top of a steady flow tank and a container, the air runs along with the water in the pipe network system in the form of free bubbles to form an air bag or an air plug, and the running efficiency of the water conveying and distributing pipe network system is influenced. When the pipe network is in operation, power failure or maintenance and pump stop occur, and negative pressure can occur to cause the pipeline to vibrate or break. 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 products which are both environmentally friendly and hygienic.
Disclosure of Invention
An object of the utility model is to solve the above-mentioned current problem that exists, provide an occupation space is little, both environmental protection, sanitary one kind again has inlet and outlet air filtering capability discharge valve.
The utility model discloses a realize like this: the upper portion welding of casing has the connection closure plate, install the disk seat on the connection closure plate, the disk seat passes through threaded connection cover type nut, be equipped with the exhaust hole on the cover type nut, the disk seat passes through the hinge joint lever support, install sealed plug on the lever support, lever support connects the floater, the welding has the valve pocket that communicates with each other of intercommunication quarter butt and casing on the connection cover plate, the upper cover staving is installed on the upper portion of casing, multilayer stainless steel sintering net or stainless steel powder sintering cassette is installed to upper cover staving upper end adoption spinning connection structure, form filterable upper chamber body, the intercommunication quarter butt passes multilayer stainless steel sintering net or stainless steel powder sintering cassette, and the installation is equipped with the lock nut and is connected and compress tightly, the intercommunication quarter butt is connected with the table valve, the manometer is connected with the table valve. The lower part of the shell is connected with the connector through threads, a sealing ring is installed on the lower part of the shell, and a filtering hole is formed in the inner hole of the connector.
The utility model has the advantages that the product is arranged at the corner or the highest point of the pipeline of the water supply and distribution pipe network and the water supply system of the secondary booster pump station, effectively discharges and releases free air mass in the system to achieve the normal working state, when water enters the pipeline, the sealing rubber plug on the lever bracket and the valve seat are in an open state, a large amount of air can be discharged, when the air is exhausted, the water enters the valve cavity, the floating ball floats to lift the lever bracket, the sealing rubber plug and the valve seat are closed, the air exhaust is stopped, and a small amount of gas can be naturally generated when the water in the pipeline normally runs, the gas can be gathered at the upper part in the pipeline and enters the valve cavity, the water level in the valve cavity is reduced when certain pressure is reached, the floating ball descends along with the water, the sealing rubber plug on the lever bracket is opened with the valve seat, the gas can be discharged from the vent hole on the cover-shaped nut and is communicated with the atmosphere through the multilayer stainless steel sintering net or the stainless steel powder sintering filter plate. When the water supply system has power failure and water in the pump stopping pipeline is empty, negative pressure can occur, the vacuum inhibition effect can be achieved, and the safety of the pipeline is ensured. The upper end of the upper cover barrel body adopts a spinning connection structure to install a plurality of layers of stainless steel sintering nets or stainless steel powder sintering filter sheets, and dust particle harmful gas can be effectively filtered and intercepted to enter a water delivery system, so that the pollution to drinking water is avoided.
