Abstract
The utility model discloses a unidirectional solenoid valve whose aim is to combine a check valve into a solenoid valve to omit one valve body which has high cost. The making method is that the outlet side of the valve hole of the solenoid valve is served as the base of the check valve, and the inner circle of the valve hole is used for guiding to omit a guiding element. The core of the check valve comprises more than three valve clacks comprising claw form objects, and valve plates connected with the valve clacks. When the pressure of the side of the outlet is greater than the pressure of the inlet side, core of the check valve presses the base of the check valve under the function of the gravity or the elastic force of a spring to prevent the medium from flowing back. The utility model which is convenient to mount and dismount has the advantages of compact structure and low cost, and can be used for the automatic control of industrial pipelines.
Description
The utility model relates to a kind of solenoid valve, and relating more specifically to a kind of medium can only be from import to exporting folk prescription to the solenoid valve that flows.
The solenoid valve of in automatic production, using, closing of spool relies on the pressure of medium to it, the own gravity of also dependence that has, spring force or the two have both at the same time.When the phenomenon that flows backwards just appears during greater than the entrance point certain value in the outlet end pressure of solenoid valve.Liquid tank temperature control apparatus is for example controlled the steam and the cold water of inflow heat exchanger respectively with two solenoid valves, when steam and cold water pressure not simultaneously, will scurry into the other side's pipeline.
Address this problem the at present industrial way that generally adopts and still after solenoid valve, add an one-way valve (or claiming safety check) again.
The purpose of this utility model is to save independent safety check, proposes a kind of unidirectional electrical magnet valve that is suitable for using on the industrial pipeline simple in structure.Design is such.Because the break-make of electromagnetic valve medium is usually only with a side that connects the valve opening of importing and exporting, just make main valve seat in a side of valve opening, the main valve plug that is driven by electromagnetic actuator leaves or contacts the purpose that reaches control with it, so the opposite side of valve opening just can be used as paying of non-return, valve seat is mixed suitable non-return valve core and just can be saved an independent valve body.
Further design is a structure of selecting non-return valve core, is the assemblying body of valve block and flap.Valve opening is garden shape normally, can make full use of as director element.Flap comprises the pawl that three slit bamboo or chopped woods of hollow are above, and periphery can be slided in valve opening at same garden cylinder, valve block link to each other with flap one side can with a pair valve seat driving fit.After main valve plug left main valve seat, medium was washed non-return valve core open and is flowed out from the space of flap.After main valve plug was pressed to main valve seat, non-return valve core was pressed under the elastic force effect of gravity or spring and is paid valve seat, has prevented the refluence of medium.Also valve block and flap bulk-breaking can be made for improving sealability, therebetween is in addition fastening again after with soft seal ring.
The utility model has the advantages that simple and compact for structurely, the valve opening two sides all fully is used, saved a valve body that cost is high, utilize the valve opening guiding to save director element again and dwindled axial dimension.Therefore the utility model can take up space less, makes simple installation, and can reduce cost.
The contrast accompanying drawing is described further in conjunction with the embodiments below.
Fig. 1 is the sectional view of the unidirectional electrical magnet valve that the utility model proposes.Referring to accompanying drawing 1, the electromagnetic valve structure pattern of present embodiment is straight ejector half solenoid valve, is combined by electromagnetic actuator (20) and valve (10).Valve comprises valve body (1), valve body (1) determining import (19), the outlet (14) of media flow and import and export between valve opening (16), between import (19) and the valve opening (16) main valve seat (13) is arranged, between valve opening (16) and the outlet (14) valve seat (18) of paying is arranged, the subtend main valve seat has main valve plug (2).Valve gap (4) is fixed on the valve body (1), is fixing electromagnetism execution architecture (20) on the valve gap, and the armature (3) in the electromagnetic actuator (20) is bound up with spool (2).Subtend is paid valve seat non-return valve core (5), it is made up of flap (56), valve block (59) and seal ring (54), one side of flap (56) is four slit bamboo or chopped wood pawls, the pawl periphery is slided in valve opening (16), the opposite side of flap (56) is a bolt, pass the endoporus of valve block (59), nut (7) and stopping shim (6) tighten together flap (59), valve block (56) and the seal ring (54) that is clipped between the two.Valve body (1) is right against valve opening (16) outlet side place and is also fixing a stifle (8), is adorning a pressure spring (9) between stifle (8) and non-return valve core.
When the coil (12) of electromagnetic actuator cut off the power supply, main valve plug (2) was pressed on the main valve seat (13) under the effect of spring (11) and gravity, and medium can not flow to outlet from import.Non-return valve core (5) is pressed under the effect of spring (9) and is paid valve seat (18) simultaneously.Medium can not flow to import from outlet.After coil (12) energising, main valve plug (2) leaves main valve seat (13) under the effect of electromagnetic force, and medium is washed non-return valve core (5) open when an orifice flow goes out, and flows to outlet from the gap of the pawl of flap (59).If this moment, the pressure of inlet was lower than the outlet port, then non-return valve core is pressed to down in spring (9) effect and is paid the valve seat medium and just can not flow backwards.
Obviously, the utility model has only installed safety check additional at the valve opening outlet side of solenoid valve, so it has nothing to do with other structural type of solenoid valve.For example can be combined into safety check at the main valve hole outlet side according to principle described in the utility model too for the pilot-type solenoid valve of contacting directly with the pipeline contact.More it doesn't matter as for the pattern of pilot valve, often open, normally closed, self-sustaining is all the same.Again for example, valve core of main valve can be a diaphragm, also can be piston or other pattern or the like.For the solenoid valve (claiming flow control valve again) of continuous control flow, the utility model is suitable for too.
