Изобретение относитс к арматуростроению И может быть использовано, например, в устройствах очистки сжатого воздуха в воздушных магистрал х промышленных предпри тий дл автоматического сброса жидких фракций в дренаж.The invention relates to the valve industry and can be used, for example, in compressed air purification devices in the air mains of industrial plants for the automatic discharge of liquid fractions into the drain.

Известен автоматический конденсатоотводчик , содержащий корпус, подпружиненный затюрный орган и сливное отверстие 1.Known automatic steam trap, comprising a housing, a spring-loaded valve body and a drain hole 1.

Такой конденсатоотводчик позвол ет по мере накоплени жидких фракций над запорным органом сбрасывать их в сливную магистраль.Such a trap allows, as the liquid fractions accumulate above the closure body, to discharge them into the drain line.

Однако при изменении давлени в магистрале такое устройство требует дополнительной регулировки.However, when the pressure in the line changes, such a device requires additional adjustment.

Целью изобретени вл етс упрощение конструкции клапана и расширение его функциональных возможностей.The aim of the invention is to simplify the design of the valve and expand its functionality.

Эта цель достигаетс тем, что в корпусе клапана, содержащем сливные отверсти , установлена втулка, в которой выполнены кольцевые выточка и каналы, а на торце , обращенном в полость корпуса, установлен полый стержень, длина которого больше максимально возможного уровн отделенных жидких фракций, посредством которогоThis goal is achieved by installing a sleeve in the valve body, which has drain holes, in which annular undercuts and channels are made, and a hollow rod, the length of which is greater than the maximum possible level of separated liquid fractions, is installed on the end face facing the body cavity.

выточка сообщена с полостью корпуса, причем на боковой поверхности втулки выполнены продольные канавки, посредством которых полость корпуса соединена с дрена-жем , а запорный орган выполнен в видеthe undercut is communicated with the cavity of the housing, with longitudinal grooves on the side surface of the sleeve, through which the housing cavity is connected to the drainage chamber, and the locking member is designed as

Claims

2Q by an annular recess 3 connected by channels 4 with a cavity of a water separator 5. A ring 6 is placed in an annular recess, spring-loaded 7. A longitudinal grooves 8 are made on the side surface of the sleeve, which together with the holes 9 of the housing form channels connecting the moisture separator cavity to the drain pipe 10. At the end of the sleeve there is a hollow rod 11, the length of which is greater than the maximum possible height of the layer fractions contained in the moisture separator. The outer diameter of the annular undercut 3 is larger than the outer diameter of the ring 6. The cross-sectional area of the opening of the hollow rod 11 and the channels 4 of the sleeve 2 is larger than the total cross-sectional area of the longitudinal grooves 8 on its lateral surface. The valve operates as follows. When the flow of compressed air into the cavity of the separator 5 under pressure, part of it enters through the opening of the hollow rod 11 and the channels 4 into the annular recess 3 of the sleeve 2 under the ring 6 and, opening the spring 7, presses the ring 6 to the housing 1, closing the channel formed by the longitudinal grooves 8 on the side surface of sleeve 2 and holes 9 in housing 1 connecting the cavity of the water separator 5 with the drain 10. The liquid fractions separated from compressed air in the form of water and oil accumulate in the cavity of the water separator. When the flow of compressed air is stopped, the pressure in the cavity of the separator 5 drops, the ring 6 under the action of the spring 7 is embedded in the annular recess 3 and opens a channel connecting the cavity of the separator with the drainage. The liquid fractions are drained by gravity into the drainage. The implementation of the locking device in the form of a spring-loaded ring provides a reliable plane for blocking the channels and the release of heavy fractions into the drainage. The presence of a hollow rod mounted at the end of the sleeve and having a length greater than the maximum possible height of the layer of liquid fractions located in the cavity of the water separator prevents them from entering the annular undercut of the sleeve and eliminates the opposition of their spring pressure when the ring returns to its original position and opening channel discharge of liquid fractions in the drainage. The implementation of the sleeve with an outer diameter greater than the outer diameter of the ring ensures reliable opening of the discharge channels of the liquid fractions, and the execution of the stem hole and the channels connected to the annular undercut on the sleeve with a cross-sectional area longer than the longitudinal grooves on it ensures valve speed. The use of a valve in the compressed air mains of industrial enterprises simplifies their operation without requiring constant monitoring of the presence of liquid fractions in the water separators, since at the end of the operation with pneumatic tools the air lines are turned off, and this is the condition necessary and sufficient for automatic actuation of the valve locking mechanism. Claim 1. A valve comprising a housing with drain holes and a locking member, characterized in that, in order to simplify the design of the valve and expand its functionality, a sleeve is installed in the housing, in which an annular recess and channels are made, a hollow rod is installed in the body cavity, the length of which is longer than the maximum possible level of the separated liquid fractions, whereby the undercut communicates with the body cavity, with the longitudinal side of the sleeve being made grooves, through which the cavity of the housing is connected to the drainage, and the locking body is made in the form of a spring-loaded ring installed in the annular groove of the sleeve.

2. A valve according to claim 1, characterized in that the cross-sectional area of the aperture of the hollow rod and the bushing channels is larger than the total cross-sectional area of the longitudinal grooves on its lateral surface.
