Abstract
The utility model relates to the field of machinery, particularly to a high-voltage electromagnetic valve. The high-voltage electromagnetic valve comprises an electromagnetic valve body, wherein a first seal component and a second seal component are arranged in a valve cavity, a first elastic component is arranged between the first seal component and the second seal component, a valve core is arranged on the circumference of the first elastic component, a sleeve is arranged on the outer side of the valve core, an electromagnetic valve coil is arranged outside the sleeve, a second elastic component is arranged at the bottom part of the sleeve, an air outlet is arranged on the right side of the second elastic component, an upper reach through hole is communicated with a first air inlet, and a lower reach through hole is communicated with a second air inlet and a third air inlet respectively. The high-voltage electromagnetic valve is characterized in that the seal components of the electromagnetic valve are made of PEEK materials, and the flowing bore diameter of both the upper reach through hole and the lower reach through hole of the electromagnetic valve is 0.5mm. The high-voltage electromagnetic valve has the advantages that through adopting the high-performance PEEK materials, the problems of seal and anti-abrasion existing in the high-voltage electromagnetic valve are solved; and through reducing the flowing bore diameter of both the upper reach through hole and the lower reach through hole of the electromagnetic valve, the power consumption of the coil is reduced, and the danger of coil burn due to too high temperature rise is avoided.
Description
Technical field
The utility model relates to mechanical field, relates in particular to a kind of high-pressure solenoid valve.
Background technique
Gas-liquid linked final controlling element power gas is pressurized gas (can reach 9.9MPa), realize remote electrically controlled or controls function automatically, needs adapted can control the solenoid valve of high pressure, but high-pressure solenoid valve sealing and life problems are this industry difficult points always.
High-pressure solenoid valve adopts the mode of metal to metal seal or " O " RunddichtringO more at present.But, be hard the contact between metal and the metal, can't guarantee that solenoid valve zero reveals, particularly at elevated pressures (〉 5MPa) and under the situation, the sealing of solenoid valve is poorer.Though type circle sealing means can be accomplished good seal, solenoid valve is after repeatedly moving " O ", and Sealing is damaged easily, need safeguard or change and could guarantee its sealability that practicability is not good enough this moment to the seal ring of solenoid valve.
In addition, the circulation aperture is bigger than normal in the existing high-pressure solenoid valve design, makes the stressed increase of seal face, and the spring type selecting also strengthens simultaneously, causes required electromagnetic force to increase, and promptly the coil quantity of coil winding increases, and power consumption strengthens, when serious even burn out coil.And because high-pressure solenoid valve is generally all used as secondary control (guide's control), actual do not have specific (special) requirements to its flow.
Summary of the invention
The problem that the utility model is bad for the sealing that solves existing high-pressure solenoid valve and working life is short, the technological scheme of taking is: (working pressure can arrive 9.9MPa to a kind of high-pressure solenoid valve, power consumption is 2.5W), comprise solenoid valve body, be provided with first sealed member and second sealed member in its valve pocket, between first sealed member and second sealed member, be provided with first elastic member, the periphery of first elastic member is a spool, and the spool outside is outside equipped with electromagnetic valve coil for sleeve pipe and at sleeve pipe; The bottom of sleeve pipe is provided with second elastic member; The second elastic member right side is an air outlet hole, and the last opening and first suction port are communicated with; Following opening is communicated with second inlet hole and the 3rd inlet hole respectively, and it is characterized in that: the sealed member of solenoid valve is the PEEK material; The last opening of solenoid valve and the circulation aperture of following opening are 0.5 millimeter.
Here, described first elastic member and second elastic member are spring.
Here, under the prerequisite that does not influence power, the aperture of solenoid valve can be slightly larger than or be slightly less than 0.5 millimeter.
During the solenoid valve action, spool is subjected to electromagnetic force influence, produces the power that overcomes first elastic member and moves upward.Opening is sealed on this moment, and following opening is opened, and suction port enters gas, be full of whole cavity after, the relief opening by valve pocket side, the first spring members place is discharged.
If select first suction port as the power gas source interface, when solenoid valve was not switched on, outlet and inlet were connected, and can realize solenoid valve outage holding function;
If select the second or the 3rd suction port as the power gas source interface, when solenoid valve was switched on, outlet and inlet were connected, and can realize solenoid valve energising holding function.
Advantage of the present utility model: sealing and the wear-resistant problem having utilized high performance material PEEK to solve to exist in the high-pressure solenoid valve; By reducing the circulation aperture of solenoid valve, reduced the power consumption of coil, it is too high and burn out the danger of coil to avoid temperature rise.
