The present invention may be used as common one-way valve and can realize back flow under control of signal.
Description
Technical field
The present invention relates to the position control valve of technical field of fluid transmission, specifically relate to a kind of sea water hydraulic 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.This dual mode has common shortcoming: complex structure; Leakage is not easy control; Weight is big.
For with seawater as working medium and be placed directly in the hydraulic system of abyssal environment; because the corrosivity of seawater is strong, abyssal environment pressure height, pollute big; silt in the water also will produce serious erosion and scraping action to electromagnet, spool, valve body, and silt enters and causes between spool and the valve body that spool is stuck simultaneously.If the electric control one-way valve that ground environment is used directly uses,, and make the very fast inefficacy of electric control one-way valve or at all can not use owing to casing rigidity is not enough, poor sealing performance, reason such as not corrosion-resistant in the deep-sea.
Summary of the invention
The object of the present invention is to provide a kind of sea water hydraulic electric control one-way valve, can realize comprising the common non-return valve function of pressurize, can under the control of electrical signal, realize reversing motion again.It can use sea (light) water to be medium, and can directly soak in water, also has high pressure resistant, corrosion resistant characteristic.
The technical solution adopted for the present invention to solve the technical problems is: be made up of electromagnet and one-way valve.
1) described electromagnet is the seawater electromagnet: its magnetic core pipe assembly includes nose end lid, magnetic core barrier part and atresia end cap, the porose end cap of a termination of magnetic core barrier part, another termination atresia end cap of magnetic core barrier part; Be equipped with at step-like armature lifter in the magnetic core pipe assembly, after the small end of armature lifter passed porose end cap, the small end of armature lifter was exposed at outside the magnetic core pipe assembly; Coil block comprises solenoid housing and coil, be contained in outside the magnetic core pipe assembly, the end cap nut is threaded with the atresia end cap, be pressed on side of solenoid housing, the bi-side of solenoid housing are equipped with the first Sealing circle, second seal ring respectively, and the rod end lid is exposed at the outer side of solenoid housing the 3rd seal ring is housed;
2) described one-way valve: comprise 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; In the valve body axial hole of throttle orifice one side armature lifter is housed, armature lifter can contact with spool small end end face.
The useful effect that the present invention 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;
4, sea water resistance: can use sea (light) water to be medium, and can directly soak in water;
5, high pressure resistant: high pressure can both bear in inside and outside portion, can use in the deep-sea;
6, corrosion-resistant: as to adopt too alloy or stainless steel as housing, so have excellent corrosion resisting performance.
The present invention both can be used as common one-way valve usefulness, can realize reverse flow under the control of electrical signal again.It can be applicable to in the Hydraulic Power Transmission System of sea (light) water as medium, and external environmemt can directly be the seabed.
