Abstract
Description
Technical Field
[0001] The present application relates to a low-pressure rapid air inlet and outlet valve, belonging to the technical field of low-pressure closed containers for municipal water supply and drainage projects. Background Art
[0002] Water supply and drainage projects, as a key component of municipal infrastructure construction, are experiencing rapid growth. Water storage tanks and water tanks, as storage equipment, play a crucial role in these projects. Currently, most storage equipment is non-pressurized. This leads to excessive volume requirements, while openings can easily cause secondary water pollution or odor leakage. The demand for enclosed, pressurized storage equipment is growing across various projects, and the rapid intake and exhaust requirements of these equipment urgently need to be addressed. Utility Model Content
[0003] In view of this, the present application provides a low-pressure rapid air inlet and outlet valve to quickly balance the internal pressure of a sealed storage device and prevent the sealed storage device from bursting or sinking.
[0004] Specifically, this application is implemented through the following solutions:
[0005] A low-pressure rapid inlet and exhaust valve comprises a lower valve body and an upper valve body, wherein the upper valve body is fixed on the lower valve body, and the upper valve body and the lower valve body form an air flow channel, in which a latex ball is arranged, an exhaust hole is arranged on the side wall of the upper valve body, and a bell tube is arranged in the upper valve body, the bell mouth of the bell tube is located on the side close to the latex ball, and the outer periphery of the bell mouth is fixed to the inner wall of the upper valve body below the exhaust hole, and the lower end opening is lower than the top surface of the latex ball, so that when the latex ball is subjected to its own weight or negative pressure, it can be separated from and fitted with the inner wall of the bell tube, thereby completing the functions of inlet, exhaust and pressure bearing.
[0006] Furthermore, as a preference:
[0007] The trumpet tube and the upper valve body are an integrated structure.
[0008] The upper valve body is provided with a plurality of exhaust holes. More preferably, the exhaust holes are provided in three groups, and the three groups of exhaust holes are distributed at different heights. Each group of exhaust holes is provided with at least one exhaust hole.
[0009] The latex ball is suspended in the upper valve body by a steel chain. More preferably, the steel chain is a stainless steel chain. One end of the steel chain is fixed to the top of the upper valve body, and the other end passes through the trumpet tube and is fixed to the latex ball.
[0010] The upper valve body is fixed on the lower valve body through a flange group.
[0011] The lower valve body is fixed to the exhaust hole of the sealed regulating and storage equipment through a flange plate.
[0012] The low-pressure rapid inlet and exhaust valve provided by the present application fixes the lower valve body at the exhaust hole of the closed regulating and storing equipment, and the upper valve body is installed thereon. The exhaust hole is set on the side wall of the upper valve body, and a trumpet is set on the inside. The latex ball is located in the upper valve body at a position corresponding to the trumpet. The exhaust hole of the closed regulating and storing equipment-lower valve body-bell tube-exhaust hole of the upper valve body constitutes an air flow channel. Under the action of its own weight or negative pressure, the latex ball falls and separates from the trumpet, and the air flow channel is unblocked. At this time, the device can perform the air intake and exhaust functions; when the closed regulating and storing equipment is filled with liquid, the latex ball fits on the lower end opening of the trumpet under the action of buoyancy, and the air flow channel is closed. At this time, the device performs the pressure-bearing function. The relative position of the latex ball and the trumpet changes to realize the on-off of the air flow channel, thereby quickly balancing the internal and external pressures of the closed regulating and storing equipment, reducing the wall thickness requirements of the closed regulating and storing equipment, and greatly reducing the equipment cost, thereby reducing the project investment.
