Abstract
The utility model relates to a temp. automatic adjusting valve, which comprises a valve body, a flange screw hole, a sealed hydraulic tank, cylinders, cylinder push rods, valve covers, back flow caps, etc. The utility model is characterized in that the sealed hydraulic cylinder (3) is fixed in the valve body (1) by a supporting board, one end of the sealed hydraulic tank is provided with a plurality of cylinders (4), the push rods (5) are arranged in the cylinders, and the top end of the cylinders are provided with the valve covers (6) with the back flow caps. The push rods are pushed to control the switch of the valve using the principle of liquid heat expansion and cold contraction in the sealed container. The utility model has the advantages of simple structure, stability, reliability, easy fabrication, and low cost; when the utility model works, people do not need to manage, other energy source can not be consumed, and the utility model can be used for heating systems of industrial and mining establishments and life.
Description
The utility model relates to the fluid control valve technical field, specifically is a kind of automatic temperature control valve.
In industrial heating and civilian heating system, need in whole heat supply heating system, regulate the flow of each heating radiator place heat-transfer working medium (hot water, vapours etc.) with its temperature of balance.At present, adjustment generally adopts two kinds of methods: 1, adopt simple joint door manual shift, it is many that the method takies manpower, and degree of regulation is poor; 2, adopt electronic, pneumatic servo operation valve, these two kinds of equal complex structures of method, power consumption is high, the cost height.
The purpose of this utility model is to provide a kind of other energy that do not need, and can realize the self-regulating automatic temperature control valve of temperature again.
The utility model adopts following technical scheme:
The automatic adjusting control valve of a kind of temperature, form by institutes such as valve body, flange screw hole, sealed hydraulic jar, cylinder barrel, cylinder barrel push rod, valve cover, refluence caps, in the valve body (1), be fixed with sealed hydraulic jar (3) by support plate, the one end is equipped with a plurality of cylinder barrels (4), push rod (5) is housed in the cylinder barrel, and the valve cover (6) of band fair water cone is equipped with on its top.
Volume increases after the liquid in the closed container or gas are heated, and promotes valve mandril and moves forward, until valve-off; Otherwise, valve open then; Owing to the incompressibility of liquid, valve can not influence because of the variation of pipeline inner pressure in the automatic switch process again.
Advantage of the present utility model is: the adjusting of valve is consumes energy (comprising power) not; Do not need personal management and control; In heat supplying process, make the total system self-poise; Energy-saving effect is obvious, the efficient height; This valve mechanism is simple, produces easily, and production cost is low, high efficiency, thus filled up the blank of this respect.
Further specify the utility model below in conjunction with drawings and Examples.
Accompanying drawing is the sectional view of the utility model automatic temperature control valve.
Among the figure, 1, valve body, 2, the flange screw hole, 3, the sealed hydraulic jar, 4, cylinder barrel, 5, the cylinder barrel push rod, 6, valve cover, 7, fair water cone; Direction indication shown in the arrow comes the gas direction from the water that comes of boiler among the figure.
When the temperature of the fluid working substance of this valve of flowing through was on the low side, because principle of expanding with heat and contracting with cold, airtight hydraulic tank 3 and cylinder barrel 4, push rod 5 all shrank, make the valve gap 6 of band fair water cone 7 descending, choke area increases, and resistance reduces, the flow of the fluid working substance of this valve of flowing through is increased, bring more heat; When the temperature drift of heat-transfer working medium, process is opposite, the elongation of expanding of airtight hydraulic tank, and the valve gap 6 of band fair water cone 7 is up, and choke area reduces, and the heat-transfer working medium flow reduces, and brings less heat, thereby has realized the automatic adjusting of temperature.
The utility model can be widely used in industrial and mining enterprises and life heating system.
