(54) ШЛАНГОВЫЙ РЕГУЛИРУЮЩИЙ КЛАПАН(54) HOSE CONTROL VALVE

1one

Изобретение относитс к арматуростроению и может быть использовано дл регулировани расхода среды, в частности дл регулировани расхода воды, охлаждающей конденсатор холодильной установки.The invention relates to a valve and can be used to control the flow of the medium, in particular to control the flow of water cooling the condenser of the refrigeration unit.

Известно регулирующее устройство, содержащее эластичную мембрану, выполненную в виде втулки, котора одновременно вл етс чувствительным элементом и клапаном 1.A regulating device is known which contains an elastic membrane made in the form of a sleeve, which is simultaneously a sensitive element and a valve 1.

Недостатком известного устройства вл етс Невозможность его использовани в качестве регул тора расхода охлаждающей воды На конденсатор ввиду отсутстви узла настройки. Кроме того, в случае нарущени цельности мембраны охлаждающа вода будет химически загр знена холодильным агентом, а холодильна установка окажетс неработоспособной.A disadvantage of the known device is the Impossibility of its use as a regulator of the flow of cooling water to the condenser due to the absence of a tuning unit. In addition, in the event of a breach of the integrity of the membrane, the cooling water will be chemically contaminated with a cooling agent, and the refrigeration unit will be inoperative.

Наиболее близким к предлагае.мому по технической сущности вл етс регулирующий щланговый клапан, в корпусе которого размещен регулирующий орган, выполненный в виде упругого щланга, установленного в перфорированном кожухе, причем полость между стенками корпуса и шланга частично заполнена легкокип щей жидкостью, выполн ющей функцию чувствительного элемента 2.Closest to the proposed technical essence is a control hose valve, in the case of which a regulating body is placed, made in the form of an elastic hose installed in a perforated casing, and the cavity between the walls of the case and the hose is partially filled with boiling liquid that performs the function of a sensitive element 2.

Известный клапан также не обеспечивает возможности настройки на поддержание требуемого параметра и недостаточно надежен в работе, поскольку чувствительный элемент - легкокип ща жидкость - контактирует с поверхностью щланга.The known valve also does not provide the ability to adjust to maintain the required parameter and is not reliable enough in operation, since the sensitive element — a light boiling liquid — contacts the surface of the hose.

Цель изобретени - расщирение функциональных возможностей и повыщение надежности .The purpose of the invention is to extend the functionality and increase reliability.

Дл достижени указанной цели в шлангово .м регулирующем клапане на корпусе установлен щтуцер дл подвода термочувствительной среды, а чувствительный элемент выполнен в виде охватывающей щланг глухой спиральной трубки, открытый конец которой закреплен в корпусе и подсоединен к щтуцеру, а глухой - снабжен винтом с регулировочной гайкой, подпружиненным относительно корпуса.To achieve this goal, a shtucer is installed in the hose control valve on the housing to supply a temperature-sensitive medium, and the sensing element is designed as a blind spiral tube covering the hose, the open end of which is fixed in the housing and connected to the connector, and the deaf is equipped with a screw with an adjusting nut , spring-loaded relative to the housing.

На фиг. 1 изображен клапан в поперечном разрезе; на фиг. 2 - разрез А-А на фиг. 1.FIG. 1 shows the valve in cross section; in fig. 2 shows section A-A in FIG. one.

Claims

The valve consists of a body 1 and connecting flanges 2. Between the body 1 and the flanges 2, the ends of the elastic hose 3 are clamped, which is located inside the helix 4, made of a deaf elliptical tube. To connect the internal cavity of the tube to the source of the heat-sensitive medium, it is fitted with a fitting 5 fixed in the housing 1 with a nut 6. To adjust the elasticity of the spiral 4 and adjust the valve to the required flow, the blind end of the spiral tube is connected to the screw 7, which is stretched by a spring 8 that abuts in the housing 1 valves in the nut 9. The valve works as follows. The cooling water passes inside the elastic hose 3 and is fed to the cooling of the condenser. The amount of water supplied and its temperature will determine the condensing pressure of the refrigerant perceived by the coil 4 connected by means of a nozzle 5 with a connecting tube to the condenser. In the event of an increase in condensation pressure (for example, when the cooling water temperature rises), the coil 4 will increase the twisting radius, which will lead to an increase in the flow area of the flexible hose 3 and, consequently, to an increase in the flow of cooling water. The latter, in turn, will contribute to the intensification of the heat sink and a decrease in the condensation pressure. In the event of a decrease in the condensation pressure of the tubular coil 4, it will compress and reduce the flow area of the elastic hose 3, which will reduce the water flow and will increase the condensation pressure. The elasticity of the tubular coil 4 can be changed by changing the force of the spring 8 by means of the nut 9, thereby setting the valve to maintain the required condensation pressure. Techno-economic efficiency of the proposed valve is reduced to expanding the functionality by adjusting to maintain the desired parameter, as well as to increase its reliability, since the presence of the spiral pipe prevents the refrigerant from contacting the cooling water in case of tightness of the hose. Claims of the invention A hose control valve, in the housing of which a regulating member, made in the form of an elastic hose, and a sensitive element, are located, in order to expand its functionality and increase its reliability. A fitting for supplying a temperature-sensitive medium is installed on the housing, and the sensing element is designed as a blind spiral tube covering the hose, the open end of which is fixed in the housing and connected to the connector, and the blind one is equipped with a screw with an adjusting nut spring-loaded relative to the housing.
