Detailed Description
As shown in fig. 1, the present embodiment provides a pressure reducing valve including a vacuum breaker, which structurally includes: 1) the pressure reducing valve is characterized in that a pressure regulating nut is arranged at the upper part of a valve body of the pressure reducing valve, a bottom cover is connected below the pressure regulating nut through a pressure spring in contact with the pressure regulating nut, a disc is arranged below the bottom cover, and the disc is arranged on a connecting piece positioned in the valve body; the rear part of the valve body is provided with a water inlet; 2) the vacuum breaker is integrally connected to one side of a valve body of the pressure reducing valve, an air port connected with the movable upper cover is formed in the top of the vacuum breaker, the bottom of the movable upper cover contacts a sealing surface through a sealing piece, and a step is arranged below the sealing piece; the bottom of the vacuum breaker is provided with a corresponding water outlet. As the pressure reducing valve integrating the pressure reducing valve and the vacuum breaker, the device reduces the installation space and the connecting pipeline, avoids leakage between the pipeline connections, has the function of vacuum breaking, and improves the use reliability of products
Further, as shown in the embodiment shown in fig. 1 and 3, a film sleeve with an adaptive specification is embedded between the bottom cover and the disc; a cross fastening bolt with adaptive specification is additionally arranged on the valve body; an O-shaped sealing ring with adaptive specification is additionally arranged at the bottom of the connecting piece; an O-shaped sealing ring with adaptive specification is additionally arranged on the movable upper cover; the bottom of the valve body of the pressure reducing valve is additionally provided with a lower cover plate. The pressure regulating nut is used for regulating the water pressure of the water outlet of the pressure reducing valve. The function of pressure spring is transmission power and bottom. The bottom cover is used for supporting the pressure spring and connecting the film sleeve, the disc and the connecting piece. The film sleeve is used for reducing pressure and sealing. The function of the disk is to support the film sleeve and reduce pressure. The function of the connecting piece is connection. The valve body is used for combining decompression and vacuum breaking of all parts. The lower cover plate is used for sealing and supporting. The function of the O-shaped sealing ring is sealing. The sealing member is used for breaking vacuum and preventing important moving parts from leakage. The movable upper cover is used for fastening, sealing and adjusting the direction of the air inlet and the air outlet. The function of the cross fastening nut is fastening.
Further, as shown in fig. 3, when water pressure enters the inner cavity of the pressure reducing valve through the water inlet of the pressure reducing valve, the water pressure is reduced to the required water pressure through the adjusting nut at the lower end of the pressure reducing valve, and then the water pressure flows out from the water outlet of the pressure reducing valve to the water outlet of the vacuum breaker end. When the water pressure of the system is positive, water reaches the sealing surface of the end of the vacuum breaker through the water level of the water outlet of the pressure reducing valve, the upward lifting and pressing of the sealing element in the vacuum breaker are overcome, and the system is more pressurized and more compact when the pressure of the system is higher, so that the water leakage is avoided when the pressure is positive. If the water pressure is too low and does not reach the sealing surface of the vacuum breaker, water flows out from the water outlet end of the vacuum breaker, and water flow cannot flow out from the air end of the vacuum breaker, so that water leakage is avoided when the water pressure is too low. When the system is under negative pressure, the air end of the vacuum breaker adds the self weight of the sealing element to the downward force of the air acting on the sealing element, and pushes the sealing element downwards to open the sealing surface. Air enters the system through the air end of the vacuum breaker to break vacuum, and after the vacuum is eliminated, the sealing element falls down to the step of the inner cavity of the breaker under the action of self weight until the water level is higher than the sealing surface of the vacuum breaker, the sealing element is sealed again, and the air is closed.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications of the utility model may be made without departing from the spirit or scope of the utility model.
