Abstract
The utility model relates to a constant temperature closed valve, which can automatically adjust the valve opening according to the fluid temperature. The problem of the original valve that the structure is complex is solved by that the structure and the position of the heat power element of the valve are improved. The valve can be closed and opened at a constant temperature through the actions of the heat expansion and cold contraction variation of the heat power element of the valve and the pressure of a system. The utility model has the advantages of simple structure, accurate temperature control, small size, and low cost. The utility model can be used for a draining valve in a steam line to discharge the constant temperature condensing water; or the utility model can be matched with a constant temperature opened valve, and the liquid can be selected and distributed according the temperature.
Description
The utility model relates to the valve that a kind of automatic constant-temperature is closed, and has specifically provided the temperature of a kind of energy according to the valve medium of flowing through, and make the self-regulating valve of valve opening.
Along with popularizing of automation, do not expend the heat power thermostatic valve of other energy, accurate with its temperature control, the characteristic of energy saving, and be widely used.But existing thermostatic valve all makes valve opening by spring, and thermocutout was housed.Make complex structure.
The purpose of this utility model is: get rid of and open valve spring and cross thermocutout.Provide a kind of simple in structure, reliable in action, constant temperature cut-off valve with low cost.
Design of the present utility model is: the big temperature-sensitive wax of the amount of expanding with heat and contract with cold is sealed in the housing, and an end Rubber Diaphragm Seal, push rod slides in guide pillar, is combined into independently heat power element.When temperature raises, the volumetric expansion of wax; Diaphragm of rubber produces deformation, and push rod is outwards moved by expansive force.When temperature reduced, the volume of wax reduced; Push rod loses expansive force, leans on the pressure promotion push rod of liquid or gas to bounce back along guide pillar, opens valve.Further design is: valve places between the housing of thermal medium and heating power element, and housing is fixed in the outlet end of valve body when valve closing, and the heat power element can not obtain the heat that new medium is written into.Reach the balance of temperature and valve opening, thereby avoided the possibility of heat power element over-temperature.Its advantage is: back down valve by system pressure; Avoided the heat power element over-temperature.Make compact structure, volume is little, and is in light weight, and cost is low.
Fig. 1 is the whole-cutaway view of the utility model close valve state.Fig. 2 is the partial sectional view of opening state.As shown in Figure 1, the constant temperature cut-off valve is made up of valve body (1), valve (2), push rod (3), guide pillar (4), glue post (5), barrier film (6), temperature-sensitive wax (7), washer (8), back-up ring (9) and housing (10).Barrier film and guide pillar are sealed in temperature-sensitive wax in the housing.
The inlet of this valve liquid stream of A end expression.(see accompanying drawing 2) during low temperature, owing to adopt diaphragm type heat power element to reduce the frictional force of push rod sidewall, so under the effect of pressure, can make liquid or gas back down valve (2), pass the aperture on the catch (8), simultaneously heat is conducted to the temperature-sensitive wax (7) in the housing (10).When temperature raise gradually, temperature-sensitive wax expanded by heating promoted barrier film (6), and the valve (2) on glue post (5) and push rod (3) top reduces the aperture of valve automatically, closes fully up to valve.
Claims (2)
1, a kind of automatic constant-temperature cut-off valve comprises and has determined import, the valve body of outlet (1), valve (2) and be fixed on the moving element sub-assembly of heat of valve outlet end.It is characterized in that housing (10) is equipped with temperature-sensitive wax (7), barrier film (6) and guide pillar (4) are sealed in temperature-sensitive wax in the housing, and push rod (3) converts the fore and aft motion of push rod to by the Volume Changes of glue post (5) with wax in the barrier film.
2, constant temperature cut-off valve according to claim 1 is characterized in that valve (2) places between the inlet and housing (10) of thermal medium, and housing is fixed in the outlet end of valve body (1).
