Description
Предметом изобретени вл етс морозостойкий вод ной затвор к манометрам паровых котлов передвижного типа, работающих в зимнее врем на открытом воздухе.The subject of the invention is a frost-resistant water seal for pressure gauges of mobile-type steam boilers operating in the winter in the open air.
Уже известны предохранительные против зз Мерзанн вод ные затворы , так называемые «сифоны, к манометрам различных паровых котлов , работающих в зимнее врем на открытом вдздухе.The safety valves against merzann water gates, the so-called “siphons, to the gauges of various steam boilers operating in the winter in the open air, are already known.
Основной недостаток такого рода затворов заключаетс в том, что лед, образзющийс в них из неспущенной воды, после прекращени работы котла часто разрывает трубку и корпус зат|зора.The main disadvantage of this kind of gates is that the ice formed in them from the unsupplied water often breaks the tube and the body of the bolt after stopping the operation of the boiler.
В предлагаемом затворе указанный недостаток устранен применением конусной формы нижней части корпуса затвора, вследствие чего лед, образующийс при замерзании воды в затворе, скользит вдоль внутренней поверхности стенок корпуса, не распира его; уровень воды в затворе поддерживаетс ниже кра конусной части корпуса, не выше кромки колпачка, навернутого на щтуцер, соедин ющий затвор с котлом.In the proposed closure, this disadvantage is eliminated by using the conical shape of the lower part of the closure body, as a result of which the ice formed during freezing of water in the closure slides along the inner surface of the walls of the body, not bursting it; the water level in the gate is maintained below the edge of the conical part of the housing, not above the edge of the cap screwed on the connector connecting the valve to the boiler.
Конструкци такого затвора исключает опасность разрыва затвора, вызывае.мую замерзанием конденсата пара, и устран ет необходимость спуска воды из затвора при остановке котла.The design of such a shutter eliminates the danger of the shutter opening caused by freezing of steam condensate, and eliminates the need for water to drain from the shutter when the boiler is stopped.
На схематическом чертеже изображен внд затвора в его вертикальном разрезе.The schematic drawing shows the shutter in a vertical section.
Затвор выполнен в виде полого двухконусного корпуса /, сверху закрытого нарезной пробкой 2 с прокладкой 3; на пробке закренлен верхний щтуцер 4, на который навертываете .манометр. В нижней части корпуса установлен нижний щтуцер 5, посредствО М которого затвор соединен с корпусом котла.The shutter is made in the form of a hollow double cone case /, on top of the closed threaded plug 2 with a gasket 3; On top of the cork, the upper shtutser 4 is attached, on which you plug a manometer. In the lower part of the body, the lower fitting 5 is installed, through which the shutter is connected to the boiler body.
В корпусе затвора оседает конденсат 6 пара, уровень которого определ етс расположением отверстий 7 в щтуцере 5; излнщек конденсата стекает в котел через канал 8 в теле щтуцера. Доступ пара из котла в .манометр прегражден затвором, так как нижн кромка колпачка 9 погружена в конденсат.In the housing of the shutter condensate 6 vapor settles, the level of which is determined by the location of the holes 7 in the clamp 5; Condensate water flows to the boiler through channel 8 in the body of the valve. The steam access from the boiler to the manometer is blocked by a shutter, since the lower edge of the cap 9 is immersed in condensate.
Особенностью устройства затвора вл етс коническа фор.ма нижней части корпуса 7; угол конуса равен или больще 90°, в результате чего замерзща вода, расщир сь, не распирает стенок корпуса, а скользит по конусу вдоль его оси.A feature of the shutter device is the conical shape of the lower part of the housing 7; the angle of the cone is equal to or greater than 90 °, with the result that the water freezes, expanding, does not burst the walls of the hull, and slides along the axis of the cone.
