Abstract
The utility model discloses a novel electrically controlled relief valve, which comprises a valve body, wherein a high-pressure oil inlet and a high-pressure oil relief port are formed on the valve body; a pressure retaining valve core is arranged inside the valve body; one end of the pressure retaining valve core is provided with a standard electromagnet; and a pressure balance hole is formed in the pressure retaining valve core. The novel electrically controlled relief valve has the beneficial effects that the valve core can be directly opened by a solenoid valve after the pressure retaining is ended, the pressure of an execution element is relieved, the control oil circuit of the traditional hydraulic control unloading valve is saved, the diversified mechanical application requirements can be met through the using pressure and flow, most of parts of the conventional hydraulic control valves are adopted, so that the parts are conveniently replaced and maintained; and therefore, the manufacturing cost is reduced, and the novel electrically controlled relief valve is easy to popularize and use.
Description
Technical field
The utility model relates to a kind of valve (hydrovalve), particularly a kind of novel automatically controlled Decompression valves.
Background technique
The hydraulic control often of Decompression valves that at present technology is ripe, this type valve often is designed with a hydraulic control mouth.When giving the fluid of hydraulic control mouth injection certain pressure.This valve is opened and is performed element and carries out pressure release.So this type Decompression valves in use needs independently its switch of hydraulic control oil circuit control.
Some automatically controlled Decompression valvess are also arranged both at home and abroad; But usually because its design and manufacturing process and conventional hydrovalve have very big difference; Maintaining is inconvenient and cost an arm and a leg, and is limited to pressure release pressure and the demand that flow can not satisfy more and more diversified hydraulic machinery equipment of the restriction control of existing technology lower electromagnet thrust.
The model utility content
To the deficiency of existing technology, the utility model provides a kind of novel automatically controlled Decompression valves.
To achieve these goals; The utility model solves the technological scheme that its technical problem adopted: a kind of novel automatically controlled Decompression valves; Comprise valve body, valve body is provided with high pressure oil inlet and high pressure oil pressure relief opening, is provided with the pressurize spool at valve inner; One end of pressurize spool is provided with standard electric magnet, and the pressure retaining valve in-core is provided with pressure compensation opening.
Described standard electric magnet connects as one through lock nut and valve body fixing compact are installed.
Be socketed with spring through the spring stop collar on the said pressurize spool.
Said valve body outer circle wall is provided with the O RunddichtringO, and inner peripheral wall is provided with Sealing axle sleeve is installed.
The beneficial effect of the utility model: this new electronic control Decompression valves of the utility model design can directly back down spool by solenoid valve executive component is carried out pressure release after pressurize finishes; Saved the control oil channel of traditional hydraulic unloading valve; Its working pressure and flow all can satisfy the user demand of variation machinery, most of Component that adopt conventional hydraulic control valve, and this is convenient for changing accessory and maintaining; Manufacture cost is reduced, be easy to promote the use of.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
A kind of novel automatically controlled Decompression valves; Comprise valve body 1, valve body 1 is provided with high pressure oil inlet 5 and high pressure oil pressure relief opening 6, in valve body 1 set inside pressurize spool 2 is arranged; One end of pressurize spool 2 is provided with standard electric magnet 3, is provided with pressure compensation opening 4 in the pressurize spool 2.
Described standard electric magnet 3 connects as one with valve body 1 fixing compact through lock nut 10 is installed.
Be socketed with spring 7 through spring stop collar 8 on the said pressurize spool 2.
Said valve body 1 outer circle wall is provided with O RunddichtringO 9, and inner peripheral wall is provided with Sealing axle sleeve 11 is installed.
Valve body 1 adopts conventional hydraulic cartridge valve mounting type design; Standard electric magnet 3 adopts conventional electromagnet; By the same alternating current 220V or the 24V coil of disposing of Environmental Conditions configuration with conventional solenoid valve; Pressurize spool 2 carries out unique design, makes its spool that can promote with the electromagnet of routine in high pressure, the big flow applying working condition carry out pressure release.
