Abstract
The provides a magnetic electric-controlled valve, comprising a valve body, an isolation gasket, a valve cover, an electro-magnetic coil, a fixed magnet, a permanent magnet, a valve rod, a pressure spring, a rubber diaphragm, a pilot-operated valve assembly, wherein, the permanent magnet is taken as a magnetic lock mechanism of the valve rod; the pilot-operated valve assembly is used to make a pilot conduction of the fluid before the valve rod opens, to make both sides of the diaphragm obtain uniform pressure; a three-way structure for fluid passage is designed at the lower part of the valve body, which strengthens the applicability of the valve. The electromagnetic valve has the advantages of sensitive and reliable opening and closing, convenient operation and strong applicability.
Description
The utility model belongs to the part that fluid-pressure system uses, particularly a kind of flowing medium magnetic force electrically-controlled valve.
When magnetic force electrically-controlled valve and flammable gas alarm coupling, be used for the automatic protection that combustible gas leakage is closed source of the gas more.Like product of the prior art, can be under the instruction of alarm automatic-closing valve, but all be by manual machinery type Open valve.Though it can be used for the safety protection of combustible gas leakage, if the position that valve is installed is improper, can be very inconvenient when the manually opened valve of user.In addition, because solenoid valve adopts significantly elastomer diaphragm sealing and mechanical caging mode, when pipeline fluid pressure greatly the time, the active force that mechanical locking is born is excessive, can cause the control valve can not regular event, even malfunctioning.
For solving the deficiencies in the prior art, the utility model has designed a kind of flowing medium magnetic force electrically-controlled valve.This electrically-controlled valve as with the flammable gas alarm coupling time, but under state of alarm automatic-closing valve.After removing warning, only need press the reset button on the alarm, solenoid valve just can be opened, and is very convenient.Owing to cancelled the mechanical pins lock mode, designed the magnetic force locking device, make the switch operation of solenoid valve sensitive reliable.
The magnetic force electrically-controlled valve that the magnetic force electrically-controlled valve of the utility model design concept is by valve body, cut off pad, valve gap, electromagnetic coil, decide iron, permanent magnet, valve rod, pressure spring, elastomer diaphragm, pilot valve constitute.Wherein: with the magnetic force locking framework of permanent magnet as valve rod; Before the valve rod breakdown action, the conducting fluid is all pressed the both sides of diaphragm in advance by pilot valve; The three-port structure of fluid passage has been designed in the bottom of valve body, has strengthened the applicability of this valve.
The structural representation of the magnetic force electrically-controlled valve that Figure of description designs for the utility model.
The embodiment who sets forth magnetic force electrically-controlled valve of the present utility model in conjunction with the accompanying drawings is as follows: by valve body (1), partition pad (2), elastomer diaphragm (9), pilot valve (10), the path of having formed valve and partition.Wherein: the bottom of valve body (1) is designed to from inlet a to the fluid line that exports b and c bypass to be installed, and also can select straight-through type or right-angle type to install.When elastomer diaphragm (9) drops to the valve seat place simultaneously with valve rod (2) under the pressure effect of spring (8), get final product throttle down.
The magnetic force control section.By neodymium-iron-boron permanent magnet (6), decide iron (5) and electromagnetic coil (4) and constitute.When valve rod (7) under the acting in conjunction of permanent magnet (6) the paramagnetic magnetic force of electromagnetic coil (4), can overcome the pressure of spring (8), at first drive pilot valve, make inlet a and outlet b or c equipressure in the valve pocket, eliminated the hydrodynamic pressure of elastomer diaphragm (9) top, drive on the elastomer diaphragm (9) and move, after promoting valve rod (7) and decide iron (5) to join, electromagnetic coil this moment (4) outage demagnetization, only depend on permanent magnet (6) can be held open state to the adhesive of valve rod (7), and be locked by deciding iron (5).Again with electromagnetic coil (4) with the strict magnetic of back current, formed and the opposite magnetic field of permanent magnet (6), the suction of permanent magnet significantly weakens, the pressure of spring (8) is brought into play, and promotes valve rod (7) and moves down, and drives elastomer diaphragm and makes valve closing.In addition, the generation and the change in the positive and negative magnetic field of electromagnetic coil (4) rely on the instruction of flammable gas alarm and fully with due to this electric current forward or backwards of exporting.
Claims (1)
1, flowing medium magnetic force electrically-controlled valve be by valve body (1), cut off pad (2), valve gap (3), electromagnetic coil (4), decide iron (5), the constituting of permanent magnet (6), valve rod (7), pressure spring (8), elastomer diaphragm (9), pilot valve (10), it is characterized in that permanent magnet (6) wherein is the magnetic force locking framework of valve rod (7); Pilot valve (10) can be prior to the breakdown action of valve rod (7) and the admittance fluid, the mechanism that the both sides of diaphragm (9) are all pressed; The bottom of valve body (1) has been designed by inlet a to the fluid medium channel that exports b and outlet c.
