Abstract

FIELD: heat supply systems; water heating radiators. SUBSTANCE: thermoregulator has valve cock and thermostat connected with it by means of union nut. Valve cock has spring-loaded rod with valve engageable with seat located inside cock. Thermostat has thermal converter made in form of bellows fitted at one end of thin-walled housing forming circular chamber together with housing which is filled with vapor-liquid working medium. At other side bellows has blind bottom. Compression spring is provided for relieving the bellows. This spring is located inside bellows and is locked with cover connected with thermostat housing. Cover has central hole where pressure rod is reciprocating. Axial forces arising at change of pressure of vapor-liquid working medium are taken up by pressure rod and are transmitted from bottom of bellows to spring-loaded rod of valve cock. Thickness of coils of compression spring relieving the bellows and their pitch are so selected that spring rests against cover in fully compressed state forming mechanical stop which keeps corrugations of bellows from folding. Valve cock is provided with swivel nozzle mounted coaxially relative to spring-loaded rod. End portion of this nozzle is made in form of hollow cylinder inside which valve rod is located. Maximum height of cylinder is dictated by amount of free travel of valve when spring is free or fully compressed. EFFECT: enhanced reliability of operation at unstable working pressure, at abnormal rise of temperature, contaminated water and reduced capacity of valve cock.

Изобретение относится к устройствам отопительной системы теплоснабжения, в частности к терморегуляторам сильфонного типа, устанавливаемым на радиаторы водяного отопления. Терморегулятор содержит вентильный кран и соединенный с ним посредством накидной гайки термостат. Вентильный кран имеет подпружиненный шток с клапаном, контактирующим с седлом, размещенным внутри полости крана. Термостат имеет термопреобразователь в виде заделанного с одного конца в тонкостенном корпусе сильфона, образующего совместно с корпусом кольцевую полость, наполненную парожидкостным рабочим теплом. С другой стороны сильфон имеет глухое дно. Для разгрузки сильфона служит пружина сжатия, которая расположена внутри сильфона и заперта крышкой, соединенной с корпусом термостата. В крышке выполнено центральное отверстие, в котором с возможность возвратно-поступательного движения перемещается нажимной шток. Осевые усилия, возникающие при изменении давления парожидкостного рабочего тела, воспринимаются нажимным штоком и передаются от дна сильфона на подпружиненный шток вентильного крана. Толщина витков пружины сжатия, разгружающей сильфон, и их шаг выбраны так, что в полностью сжатом состоянии она опирается на крышку и образует механический упор, препятствующий складыванию гофров сильфона. В вентильном кране соосно с подпружиненным штоком установлена поворотная дюза, концевая часть которой представляет собой полый цилиндр, внутри которого перемещается клапан штока. Максимальная высота цилиндра выбрана из условия обеспечения свободного хода клапана при свободном и полностью сжатом состояниях пружины сжатия, разгружающей сильфон. Терморегулятор обеспечивает надежную работу в условиях нестабильного рабочего давления в системах теплоснабжения, различной по составу и качеству воды, при нештатных повышениях температуры, загрязнениях воды и возможном снижении пропускной способности вентильного крана.The invention relates to devices for a heating heat supply system, in particular to bellows-type thermostats mounted on water heating radiators. The temperature controller contains a valve tap and a thermostat connected to it via a union nut. The valve valve has a spring-loaded stem with a valve in contact with a seat located inside the valve cavity. The thermostat has a thermal converter in the form of a bellows sealed at one end in a thin-walled casing, which together with the casing forms an annular cavity filled with vapor-liquid working heat. On the other hand, the bellows has a dull bottom. To unload the bellows, a compression spring is used, which is located inside the bellows and is locked by a lid connected to the thermostat housing. A central hole is made in the lid, in which the push rod moves with the possibility of reciprocating motion. Axial forces arising from a change in the pressure of the vapor-liquid working fluid are perceived by the pressure rod and transferred from the bottom of the bellows to the spring-loaded stem of the valve valve. The thickness of the turns of the compression spring unloading the bellows and their pitch are selected so that in a fully compressed state it rests on the cover and forms a mechanical stop that prevents folding of the bellows corrugations. A rotary nozzle is installed coaxially with the spring-loaded stem in the valve valve, the end part of which is a hollow cylinder, inside which the valve of the stem moves. The maximum height of the cylinder is selected from the condition of ensuring free running of the valve with free and fully compressed states of the compression spring unloading the bellows. The temperature regulator ensures reliable operation in conditions of unstable working pressure in heat supply systems of different composition and quality of water, with abnormal temperature increases, water pollution and a possible reduction in valve capacity.
