Description

Novel electron pressure controller

Technical field

The present invention relates to be used for the water pump water supply system electronic pressure controller of control automatically, especially relate to a kind of architecture advances of novel electron pressure controller.

Background technology

The present electronic pressure controller that uses, being used for water pump water supply system controls automatically, start or switch off the pump by opening or closing water swivel, with spring starting pressure is set, magnet steel provides signal with magnetic control element electromagnetic induction to controller, the structure of existing electronic pressure controller can not satisfy client's diversified demand, and seal element rubber diaphragm in the controller can not satisfy the demand of client to properties of product because structure and material cause product are lower mechanical life.

Summary of the invention

The object of the present invention is to provide a kind ofly have compact conformation, simple, precise control be installed, the novel electron pressure controller of dependable performance.

The present invention is achieved through the following technical solutions: a kind of novel electron pressure controller, comprise main body, be arranged on diaphragm in the body matter chamber, be pressed on the press rods assembly on the diaphragm with water inlet and water delivering orifice, and the check valve assembly in the water inlet, the built-in magnet of press rods assembly and check valve assembly, be provided with magnetic control element tongue tube with its correspondence position, tongue tube is connected with control circuit, and the main body both sides are fixed with spring flap and panel.

The electric pressure signal that the tongue tube electromagnetic induction produces in magnet and the control circuit board component is installed in the press rods assembly, be input to the IC circuit jointly with the flow electric signal of built-in magnet of check valve assembly and the generation of tongue tube electromagnetic induction, the IC circuit output signal is to LED and motor, and its output terminal is connected the startup of controlling water pump and closes with motor through relay.

Beneficial effect of the present invention is embodied in: check valve assembly and the built-in magnet of press rods assembly and tongue tube electromagnetic induction produce electric signal and control water pump water supply system automatically, and exquisite press member structural design makes the controller architecture compactness; Unique diaphragm structure design makes product higher more than 2 times than traditional product mechanical life, and dependable performance has reduced the high request to the diaphragm material.

Description of drawings

The invention will be further described below in conjunction with accompanying drawing:

Fig. 1 is the structure cut-open view of one embodiment of the invention;

Fig. 2 is circuit theory diagrams of the present invention.

Among the figure: 1, main body; 2, spring flap; 3, pressure spring; 4, press rods assembly; 5, spring base; 6, diaphragm; 7, magnet steel seat; 8, pressure magnet; 9, operation circuit board component, 10: panel; 11, non-return valve magnet; 12, check valve assembly; 13, tongue tube K1; 14, tongue tube K2.

Embodiment

As can be seen from Figure 1, a kind of novel electron pressure controller, comprise main body 1, be arranged on the diaphragm 6 in main body 1 content cavity, the spring base 5 that is pressed on press rods assembly 4, pressure spring 3 and support spring on the diaphragm 6, the check valve assembly 12 in the water inlet with water inlet and water delivering orifice, press rods assembly 4 and check valve assembly 12 built-in pressure magnet 8 and non-return valve magnet 11, be provided with magnetic control

element tongue tube

13,14 with its correspondence position,

tongue tube

13,14 is connected with control circuit assembly 9, and the main body both sides are fixed with spring flap 2 and panel 10.

In conjunction with shown in Figure 2, resistance R 1, R2, R5 capacitor C 1, C2 stabilivolt DZ1, DZ2 commutation diode D1, D2, D3, D4 and LED 1 (green) are formed power circuit, during the water system lack of water, check valve assembly 12 falls after rise, non-return valve magnet 11 makes its adhesive near tongue tube K1, because hydraulic pressure reduces, diaphragm 6 is resetting under 4 effects of press rods assembly, this moment, magnet steel seat 7 internal magnets 8 were responded to tongue tube K2, circuit is through luminotron LED2, resistance R 6 luminotrons (redness) are luminous, the indication lack of water, while resistance R 8, R11 capacitor C 4, C5 forms delay circuit, the R8 current potential raises, through IC1E, the anti-phase back of IC1B output low level " 0 ", diode D7 is low level " 0 " with IC1C input end current potential clamper in 0.7V, until the R8 potential drop during as for shutoff voltage, IC1E, IC1B exports high level " 1 ", C4 electric capacity just begins charging through R11, up to C4 voltage during greater than the connection voltage of IC1C, the IC1C output low level, triode Q1 cutoff relay REL1 discharges, its disconnection of getting an electric shock, and pump motor quits work.

Wherein R5 is the discharge resistance of C1, and R7, R9 are respectively the current-limiting resistances of K2, K1, and R4 is the biasing resistor of Q1, and D5 is the fly-wheel diode protection Q1 of REL1.

When restarting, by switch SW 1, REL1 gets electric closure, pump motor work, this moment, check valve assembly 12 was backed down by current, and K1 disconnects, diaphragm 6 is also backed down by hydraulic action, press rods assembly 4 compression springs 3, and K2 disconnects, this moment, LED2 was not luminous, IC1D imports " 1 " output " 0 ", and IC1C imports " 0 " output " 1 ", Q1 conducting, REL1 gets electric closure, the pump motor continuous working.

The press member structural design of exquisiteness of the present invention and unique diaphragm structure design make product with compact structure, dependable performance.

More than by specific embodiment technical solution of the present invention has been done to further specify, the example that provides only is an exemplary applications, can not be interpreted as a kind of restriction to claim protection domain of the present invention.Therefore, allly doing relevant any modification of the present invention or change in that identical invention condition is following, all is to be included in the scope of protection of the invention.
