Abstract
The utility model discloses a liquid pipeline pressure switch, which comprises a switch and a drive mechanism connected with the switch, characterized in that: a pressure retaining device connected with the drive mechanism, the pressure retaining device is composed of a pressure cavity, a bi-direction pressure release valve which is arranged on the pressure cavity and an elastic film sheet; the pressure cavity communicates the liquid pipeline through the bi-direction pressure release valve; the elastic film sheet connects the drive mechanism. The utility model builds a pressure cavity inside the pressure switch, which makes certain pressure difference exists between the pressure cavity inside the pressure switch and the pressure vessel through the pressure release valve; when exceeding the pressure difference, the pressure switch exports a signal. Thus, charging pressure for the pressure vessel can be kept within a certain range, decreasing liquid volume held inside the pressure vessel, decreasing starting times of the motor and guaranteeing water volume supplied to the pressure vessel each time.
Description
Technical field
The present invention relates to liquid line pressure control field, particularly a kind of pressure switch that is applicable to water treatment facilities such as water purifier, RO machine.
Background technology
Band water treatments such as water purifier, RO machine purify the device that direct drinking water is provided of filter core, because the water outlet of water treatment purification filter core water purification is slower, so generally all there is pressure vessel to store; And existing high-voltage switch gear when only being pressure arrival certain value, plays on-off action, and a decompression will cause the motor frequent starting to the pressure vessel moisturizing a little, and water purifier frequently washes, and has shortened the life-span of water purification catridge and motor; Increase the number of times and the quantity of discharge water, caused waste; Owing to the pressure vessel storing mode that last in, first out, the depositing in water of build-up of pressure container amasss problem simultaneously.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned direct drinking water device deficiency in use, a kind of pressure switch that pressurizer is arranged is provided, the pressure that charges and discharge of pressure vessel can be remained on certain limit, reduced the amount of pressure vessel delay liquid, reduced the number of starts of motor, guaranteed each quantity the pressure vessel moisturizing.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
A kind of liquid line pressure switch, comprise switch and the transmission mechanism that is connected with switch, it is characterized in that: also have pressurizer to be connected with described transmission mechanism, described pressurizer is made up of pressure chamber and the double-direction relief valve and the flexible sheet that are fixed on the pressure chamber, pressure chamber is communicated with liquid line by the double-direction relief valve, and flexible sheet connects transmission mechanism.
The utility model is constructed a pressure chamber in pressure switch, by two-way relief valve, make the interior pressure chamber of pressure switch and the pressure of pressure vessel can have certain pressure differential, just makes the pressure switch output signal in the overpressure difference.Like this, the pressure that charges and discharge of pressure vessel can be remained on certain limit, reduce the amount of pressure vessel delay liquid, reduce the number of starts of motor, guarantee each quantity the pressure vessel moisturizing.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the local structure for amplifying schematic diagram that the utility model adopts the piston bidirectional relief valve;
Fig. 3 is the local structure for amplifying schematic diagram that the utility model adopts ball-valve type double-direction relief valve.
Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
With reference to Fig. 1, the utility model comprises switch 1, and described switch 1 can adopt sensitive switch, and its shift knob 2 connects transmission mechanism 8.One pressurizer is connected with described transmission mechanism 8.Described pressurizer is made up of pressure chamber 7 and the double-direction relief valve and the flexible sheet 3 that are fixed on the pressure chamber 7, the double-direction relief valve has first valve 5 and second valve 6 of 2 diaphragm types, the opening direction that is communicated with pressure chamber 7 and liquid line 4, the first valves 5 and second valve 6 respectively is opposite.The flexible sheet 3 of pressurizer connects transmission mechanism 8, when the pressure in the pressure chamber 7 changes, flexible sheet 3 is subjected to displacement, by 1 action of transmission mechanism 8 trigger switches.
When loine pressure Pa also surpasses set point greater than pressure chamber internal pressure Pc, first valve 5 of double-direction relief valve is closed, second valve 6 is opened, liquid is by 7 inside, pipeline 4 charged pressure chambeies, and pressure chamber 7 internal pressure Pc rise, when reaching set point, pressure chamber 7 ftercompctions finish, reach the high pressure poised state this moment, cause switch 1 action by transmission mechanism 8, switch 1 enters off-state;
When loine pressure Pa decline, but also do not reach set point, first valve 5 and second valve 6 are all closed, and system keeps balance, and switch 1 is failure to actuate, and switch 1 keeps off-state;
When loine pressure Pa continues to descend, reach set point, second valve 6 is closed, and first valve 5 is opened, and pressure chamber 7 internal liquids are revealed, pressure chamber 7 internal pressure Pc reduce, when reaching set point, pressure chamber 7 rushes down to press and finishes, and system reaches the low-pressure balance state, cause switch 1 action by transmission mechanism 8, switch enters UNICOM's state.
With reference to Fig. 2, the double-direction relief valve can adopt the piston bidirectional relief valve, and it is made up of 2 opposite piston 10 and springs 9 of opening direction.With reference to Fig. 3, the double-direction relief valve also can adopt ball-valve type double-direction relief valve, and it has 2 openings that lead to pressure chamber 7 and pipeline 4 respectively, and there is a ball valve 13 centre, ball valve 13 a spring 11,12 respectively arranged up and down.The all right spring-piece type of double-direction relief valve, pilot-operated type relief valve.The double-direction relief valve is the prior art category.
Described transmission mechanism 8 can adopt cam mechanism of the prior art, leverage, linkage or other power transmitting mechanisms, and an end of transmission mechanism 8 connects shift knob 2, and the other end connects flexible sheet 3.
