Abstract
The utility model discloses a volume governor for a tightly closed liquid circulation loop. The volume governor comprises a container body connected on the circulation loop. A hollow cavity communicated with the circulation loop is arranged in the container body. The outer wall of the container body is made of extensile and flexible materials and forms a shape of a half-edge water drop. The volume governor is applied to adjustments of hydraulic pressure inside a tightly closed container, can ensure constancy of the hydraulic pressure in the container, and prevents bad effects caused by over high or over low hydraulic pressure.
Description
Technical field
The utility model relates to a kind of controlling device, particularly a kind of volume governor for the sealing fluid circulation loop.
Background technique
In the closed loop of existing liquid circulation, its seal container is rigid construction, and its volume immobilizes, when the liquid of inside, loop rises owing to shrinkage heat occurs for the change of temperature, can cause pressure change, the effect of impact circulation, container is burst in serious meeting.
Summary of the invention
In order to solve the problems of the technologies described above, the purpose of this utility model is to provide a kind of regulator of the volume for adjusting the sealing fluid circulation loop, makes to keep the constant of hydraulic pressure in the closed loop.
The technological scheme that the utility model adopts mainly is:
A kind of volume governor of sealing fluid circulation loop, comprise the vessel that is connected on the circulation loop, vessel inside is provided with the hollow reservoir that is connected with circulation loop, the outer wall of described vessel adopts ductile flexible material to make, and the outer wall of vessel consists of the shape of half of water droplet.
As further improvement in the technical proposal, for vessel being supported and protecting, described vessel is outside equipped with the shell with its coating, and described shell adopts rigid material to make.
As further improvement in the technical proposal, be provided with the sensitive switch that the controlled circulation ring current opens and closes on the described shell, when expansion of liquids is excessive in the loop, can trigger the power supply that sensitive switch cuts out circulation loop.
Preferably, described hollow reservoir is by on the three-way valve communication loop loop.
The beneficial effects of the utility model are: container outer wall of the present utility model adopts ductile flexible material to make, the hollow reservoir variable volume of vessel inside, when the expansion of liquids in the circulation loop, it is large that hydraulic pressure becomes, container outer wall expands outwardly, and it is large that the volume of hollow reservoir becomes, and can hold more water, water in the loop enters hollow reservoir, makes the hydraulic pressure in the loop keep constant; When liquid contraction, hydraulic pressure diminishes, and container outer wall inwardly shrinks, and the volume of hollow reservoir diminishes, and the water of regulator inside enters the loop and replenishes, and makes the hydraulic pressure in the loop keep constant.Volume governor of the present utility model is applicable to the hydraulic regulation of seal container the inside, can guarantee the constant of hydraulic pressure in the container, prevents the ill effect of the excessive or too small appearance of hydraulic pressure.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Embodiment
Fig. 1 is that the utility model is applied in the schematic diagram on the sealing fluid circulation loop, heating equipment 5, circuit cycle pump 6, outlet valve 7 are installed on the circulation loop 3, on circulation loop 3, also be provided with three-way valve 4, one of three-way valve 4 brings out mouthful hollow reservoir of connecting container body 1 11, the outer wall 12 of vessel 1 adopts ductile flexible material to make, outer wall 12 can expand or shrinks according to the variation of pressure, and outer wall 12 is made the shape of half of water droplet, can better adapt to hydraulic pressure.
For the vessel 1 that adopts flexible material to make being supported and protecting, also be provided with shell 2 outside the described vessel 1, shell 2 adopts rigid materials to make, and in order to save cost and attractive in appearance, can be provided with the hollow out decorative pattern on the shell 2; Shell 2 is coated on outside the vessel 1, and the volume of shell 2 is greater than vessel 1, and vessel 1 is arranged in the shell 2, also is reserved with the space of expanding for vessel 1 between vessel 1 and the shell 2.Shell 2 inwalls are provided with sensitive switch 21, when vessel 1 expands and fills up the space of shell 2, and sensitive switch 21 actions, the power supply of cut-out circulation loop 3 prevents the liquid overexpansion.
The utility model is applicable to the hydraulic regulation of seal container the inside.Volume governor of the present utility model before use, a certain amount of water is loaded onto first in its vessel 1 inside, be reserved with certain expansion space between vessel 1 and the shell 2, the large I of expansion space is calculated according to liquid volume and expansion coefficient at normal temperatures, and sensitive switch 21 is arranged in the expansion space.When the liquid contraction in the seal container, the water in the vessel 1 adds in the seal container; When the expansion of liquids in the seal container, vessel 1 adjusting (as shown in phantom in Figure 1) of automatically expanding when vessel 1 expand into the predefined value size, triggers sensitive switch 21, cuts off the power supply of circulation loop 3.Vessel 1 of the present utility model can be regulated its Volume Changes automatically with the variation of balanced hydraulic, makes the hydraulic pressure in the seal container keep constant, prevents the ill effect of the excessive or too small appearance of hydraulic pressure.
The above only is preferential mode of execution of the present utility model, as long as realize that with basic identical means the technological scheme of the utility model purpose all belongs within the protection domain of the present utility model.
