(54) ВОДОЗАБОРНОЕ УСТРОЙСТВО ОСУШИТЕЛЬНОЙ СИСТЕМЫ СУДНА 1(54) DRAINAGE SYSTEM OF THE DRAINAGE SYSTEM VESSEL 1

Изобретение относитс к судовому осушительному оборудованию и может примен тьс при осушении как на судах, так и на других плавучих объектах.The invention relates to shipboard drying equipment and can be used for drying both on ships and on other floating objects.

Известно водозаборное устройство осушительной системы судна, содержаш,ее ци- 5 линдрический экран, жестко укрепл емый на конце всасываюшего трубопровода 1.A water intake device for the drainage system of the vessel is known to contain, its cylindrical screen rigidly fixed at the end of the suction pipe 1.

Недостатком устройства вл етс значительный остаток неоткачиваемой воды на осушаемой поверхности, так как экран сни- Q жает уровень неоткачиваемого остатка воды на осушаемой поверхности до величины зазора между кра ми экрана и осуш.аемой поверхностью, поэтому система не позвол ет удал ть воду с осушаемой поверхности полностью. Кроме того, оставша с в тру- 5 бопроводе вода после остановки насоса выливаетс на осушаемую поверхность.The drawback of the device is a significant residual of non-pumped water on the surface to be dried, since the screen reduces the level of non-pumped remaining water on the surface to be dried to the size of the gap between the edges of the screen and the surface to be dried, therefore the system does not allow water completely. In addition, the water left in the pipeline after the pump stops is poured onto the surface to be dried.

Цель изобретени - повышение эффективности осушени .The purpose of the invention is to increase the drainage efficiency.

Указанна цель достигаетс тем, что 20 устройство снабжено клапанным устройством в виде стакана, сопр женного с экраном эластичной мембраной, при этом наружный диаметр стакана меньше внутреннего диаметра экрана.This goal is achieved by the fact that the device 20 is provided with a valve device in the form of a cup, coupled with an elastic membrane screen, while the outer diameter of the glass is less than the inner diameter of the screen.

На чертеже изображено устройство, установленное в осушительной системе.The drawing shows the device installed in the drainage system.

Устройство содержит экран 1, установленный на всасывающем трубопроводе 2. Экран 1 снабжен невозвратным клапаном, выполненным в виде стакана 3 с эластичной мембраной 4, причем эластична мембрана соедин ет стакан 3 с кра ми экрана, а стакан 3 опираетс опорным торцом на осушаемую поверхность 5.The device comprises a screen 1 mounted on the suction pipe 2. Screen 1 is equipped with a non-return valve made in the form of a glass 3 with an elastic membrane 4, the elastic membrane connecting the glass 3 with the edges of the screen, and the glass 3 resting on the surface to be dried 5.

Водозаборное устройство работает следующим образом.The intake device operates as follows.

Claims

After turning on the pump, the pressure in the cavity of the screen 1 becomes lower than the ambient pressure. After the vertical component of the pressure difference acting on the valve (depending on the difference in screen diameter 1 and the support face of the glass 3) exceeds the force of the valve weight (glass 3 and the elastic membrane 4), it will begin to rise and let water through the surface to be dried. 5 in the suction pipe

2. Valve lift stops when the resistance to fluid flow between the valve and the surface being dried decreases to a value at which the pressure difference acting on the valve becomes equal to the force of the valve weight. Valve resistance depends only on the weight of the valve and the area determined by the diameter of the screen 1 and the diameter of the supporting surface of the glass 3, and does not depend on the viscosity of the intake medium. Therefore, the removal of water from the surface to be dried continues even after air begins to enter the system, while the gap between the surface to be dried 5 and the supporting end of the valve cup 3 will begin to decrease and the resistance will remain unchanged. The pumping of water (water-air mixture) continues until the water is completely removed from the surface to be dried (provided that the pump is capable of pumping the water-air mixture). The proposed device can significantly improve the efficiency of drying. The invention The intake device of the drainage system of the vessel, containing a cylindrical screen rigidly mounted on the end of the suction pipe, characterized in that, in order to increase the efficiency of drying, it is equipped with a valve device in the form of a glass, coupled with a screen elastic membrane, while the outer diameter of the glass smaller than the internal diameter of the screen.
