Description
Technical field
The utility model relates to Pressure Control Technology field, specifically a kind of pressure controller.
Background technology
In industrial detection control procedure, especially compressor, water pump, boiler equal pressure equipment, all needs to control relevant pressure size.But, mostly be in the past a tensimeter to be installed, artificial monitor force situation on corresponding press device, and went unlatching according to the change of pressure or close corresponding equipment to carry out pressure in controlled pressure equipment with this and be unlikely to too high or too low.So, occurred the pressure controller of some correspondences, but such pressure controller is due to its structure problem, can only applies on the relatively little equipment of working pressure.Current product application range is quite limited.
Utility model content
The purpose of this utility model is to provide a kind of pressure controller, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of pressure controller, comprises shell, motor driver circuit, contact connection line; Reset switch is provided with above described shell centre position, label mark is provided with below reset switch, high pressure port pressure display scale table is provided with in the left side of shell, low-pressure port pressure scale table is provided with on the right side of shell, and in shell bottom, be positioned at below high pressure port pressure display scale table and low-pressure port pressure scale table and be respectively equipped with high pressure port connecting pipe and low-pressure port connecting pipe; Below described high pressure port pressure display scale table, be also provided with hold-down nut, be respectively equipped with pressure regulating screw and pressure reduction adjusting screw in shell upper end; Contact connection line comprises motor M, contact S1, contact S2, contact S3, contact S4, contact S5, contact S6, warning device, motor M one end connects 220V AC power, other end connecting terminal S5, S1 one end, contact connects 220V AC power, S3 one end, contact connects 24V direct supply, and contact S6 connects warning device.
Further, warning device connects 24V direct supply.
Compared with prior art; the utility model is a kind of automatic control device accepting pressure signal and action, in refrigeration is arranged, when compressor discharge pressure exceedes setting value; pressure controller meeting automatic shutdown circuit, makes compressor stop and play safeguard protection effect.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, in the utility model embodiment, a kind of pressure controller, comprises shell 7, motor driver circuit, contact connection line, reset switch 11 is provided with above described shell 7 centre position, label mark 14 is provided with below reset switch 11, high pressure port pressure display scale table 12 is provided with in the left side of shell 7, low-pressure port pressure scale table 13 is provided with on the right side of shell 7, and in shell 7 bottom, be positioned at below high pressure port pressure display scale table 12 and low-pressure port pressure scale table 13 and be respectively equipped with high pressure port connecting pipe 8 and low-pressure port connecting pipe 9, hold-down nut 10 is also provided with below described high pressure port pressure display scale table 12, pressure regulating screw 15 and pressure reduction adjusting screw 16 is respectively equipped with in shell 7 upper end, dextrorotation dynamic pressure adjusting screw 15, pressure set points declines, otherwise, then rise, dextrorotation dynamic pressure difference adjusting screw 16, pressure differential resetting value rises, otherwise, then decline, contact connection line comprises motor M, contact 1, contact 2, contact 3, contact 4, contact 5, contact 6, warning device, motor M one end connects 220V AC power, other end connecting terminal 5, one end, contact 1 connects 220V AC power, one end, contact 3 connects 24V direct supply, contact 6 connects warning device, and warning device connects 24V direct current, during work, in refrigeration systems, high pressure port connecting pipe 8 is connected with the exhausr port of compressor, low-pressure port connecting pipe 9 is connected with the air entry of compressor, when the discharge pressure of compressor exceedes controller high pressure set point, the contact of controller microswitch high-pressure side disconnects, cut off circuit, compressor stops, when the drop of suction pressure of compressor is to during lower than controller low pressure set point, the contact of controller microswitch low pressure end disconnects, cut off electrical equipment, compressor stops, otherwise above situation, namely Compressor Discharge Pressure drops to the lower limit of controller high pressure set point gradually, or suction pressure of compressor go back up to controller low pressure set point gradually upper in limited time, the contact closure of controller microswitch, connect circuit, compressor restarts running, so, pressure controller plays height to compressor, low-voltage variation, to freezer cooling and the reasonable running important in inhibiting of refrigeration machine.
To those skilled in the art, obvious the utility model is not limited to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present utility model or essential characteristic, can realize the utility model in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the utility model.Any Reference numeral in claim should be considered as the claim involved by limiting.
In addition, be to be understood that, although this instructions is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should by instructions integrally, and the technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
