Description
Technical field
The utility model relates to the position control valve of technical field of fluid transmission, specifically relates to a kind of electric control one-way valve.
Background technique
Position control valve at the fluid transmission field has each kinds such as one-way valve, Pilot operated check valve, solenoid directional control valve, electro-hydraulic reversing valve.One-way valve is called safety check or check valve again, and two hydraulic fluid ports are arranged on the structure, and its effect is that fluid can only be passed through along a direction, and can not reverse flow.One-way valve is done pressure retaining valve usefulness usually, or is positioned in delivery side of pump, can prevent to damage pump when pressure from raising suddenly, also can make back pressure valve and use.Pilot operated check valve is to increase the hydraulic control part on common one-way valve, and three hydraulic fluid ports are arranged on the structure, and the hydraulic fluid port of increase is called control port, connects pilot pressure.Pilot operated check valve both can be used as common one-way valve usefulness, can realize reverse flow under the pilot pressure effect again.The application of Pilot operated check valve is more, as utilizes the locking loop of Pilot operated check valve, the loop, whereabouts that prevents to conduct oneself with dignity, liquid-filling valve loop, bypass fuel outlet valve loop, accumulator oil supply loop etc.Solenoid directional control valve is made up of electromagnet, spring and changement with slide valve function, under the control of electrical signal, electromagnet energising adhesive or outage discharge, thereby directly controlling spool moves, realize communication, cut-out and the direction transformation of liquid stream or air-flow, realize commutation, sequentially-operating and the off-load etc. of transmission fluid.Because the thrust of electromagnet is limited, so solenoid directional control valve is applied in the little occasion of flow usually.In big flow occasion, adopt pressure fluid control spool to move, such selector valve is called electro-hydraulic reversing valve, and its pilot stage is exactly a solenoid directional control valve.
In some application, both needed pressurize, require again under the control of electrical signal, to realize reverse flow.Such as in the use of deep-sea pressurize sampler, transfer, sample, three processes such as lifting, wherein have only lifting process to need pressurize, two other is crossed range request and realize reverse flow under the control of electrical signal.Existing implementation has two kinds: a kind of is that electrical signal conversion becomes pressure signal, uses Pilot operated check valve then; Another kind is one-way valve and solenoid directional control valve combination, by switching the mode of oil circuit, electrical signal control commutation, one-way valve realization pressurize.It is complex structure that this dual mode has common shortcoming; Leakage is not easy control; Weight is big.
Summary of the invention
The purpose of this utility model is to provide a kind of electric control one-way valve, can realize comprising the common non-return valve function of pressurize, can realize reversing motion under the control of electrical signal again.
The technological scheme that its technical problem that solves the utility model adopts is: it is made up of electromagnet and one-way valve.Described one-way valve comprises valve body, spool and jump ring; Side at valve body has a hydraulic fluid port A mouth, valve body axially have an axial hole, the centre is a throttle orifice, one side of throttle orifice is a hydraulic fluid port A mouth, from the lining spool and jump ring outwards are housed successively in the axial hole of the opposite side valve body of throttle orifice, nose end is a hydraulic fluid port B mouth, and spool is a ladder-type, the end conical surface of spool small end matches with throttle orifice, and the little end side surface of spool has the oilhole of connecting valve in-core hole and valve body axial hole; The electromagnet push-rod of electromagnet is housed in the valve body axial hole of throttle orifice one side, and electromagnet push-rod can contact with spool small end end face.
The useful effect that the utlity model has is:
1, it had both realized pressurize, can realize reverse flow under the control of electrical signal again;
2, simple in structure in light weight;
3, cone valve sealing zero leakage.
The utility model both can be used as common one-way valve usefulness, can realize reverse flow under the control of electrical signal again.
