Description
В известных клапанах насосных хх тановок слив воды из нанорного трубопровода производ т через сверлени в оси поворотного запорно1о органа.In the well-known pump valves of the xx plant, water is drained from the nano pipeline through drilling in the axis of the rotary valve.
Вследствие небольшого сечени канала оси запорного органа слив жидкости недостаточно надежен, т. к. возможно засорение канала или замерзание воды при низкой температуре.Due to the small cross section of the channel axis of the closure member, the discharge of the liquid is not reliable enough, since the channel is clogged or the water freezes at low temperature.
С целью устранени указанного недостатка в иредлагаемом клапане его запорный орган жестко соединен штоком с дополнительным запорным органом, перекрывающим под действием пружины отверстие после слива воды.In order to eliminate this deficiency in the proposed valve, its shut-off member is rigidly connected by a rod with an additional shut-off member, which, by the action of the spring, blocks the opening after draining the water.
На чертеже изображен предлагаемы клапан.The drawing shows the proposed valve.
Клапан состоит из седла /, основного запорного органа 2 и допо.iнительного запорного оргапа 3. Оба запорных органа 2 и 3 жестко укреплены на штоке 4, подпружиненном в сторону открывани основного запорного органа. В напорный трубопровод .5 вставлена труба 6. конец которой служит седлом дл дополнительного запорпого органа.The valve consists of a saddle /, a main locking member 2 and an additional locking organ 3. Both locking members 2 and 3 are rigidly fixed on the stem 4, which is spring-loaded in the direction of opening the main locking member. A pipe 6 is inserted into the pressure pipe .5, the end of which serves as a seat for an additional valve body.
При работе насоса основной запорньп орган 2 находитс в открытом иоложении, и перекачиваема вода поступает из патрубка 7 в напорпый трубопровод 5. При этом дополнительный запорный орган 3 под действием пружины S и потока жидкости перекрывает сливную трубу 6.When the pump is in operation, the main valve body 2 is in the open position, and the pumped water flows from pipe 7 to the pressure pipe 5. At the same time, the additional valve body 3, under the action of spring S and fluid flow, closes the drain pipe 6.
При остановке насоса основной запорный орган закрываетс де;1ствием столба воды, начавшей двигатьс вниз. В это врем дополнительный запорный орган 3 открывает сливную трубу 6, и вода из трубоировода сливаетс в бак.When the pump is stopped, the main stop valve closes de; 1 because of the water column, which began to move down. At this time, the additional closure body 3 opens the drain pipe 6, and the water from the pipeline is drained into the tank.
Дополнительиый запорньп орган 3 открываетс раньше, чем основной , в результате чего происходит ослабление гидравлического удара.The secondary valve body 3 opens earlier than the main body, as a result of which the impact of the hammer is weakened.
