Abstract
The utility model provides a pilot-operated type electromagnetic valve of a compressed natural gas dispenser. The electromagnetic valve comprises a valve body and a valve core, wherein the valve core comprises a main electromagnetic valve core, an auxiliary electromagnetic valve core and a valve needle arranged on the auxiliary valve core; a closed seal ring is arranged in a sealing groove of the main electromagnetic valve core; and a ring washer is arranged outside the seal ring to fix the seal ring in the sealing groove. A sealing part of the electromagnetic valve is made of a synthetic material of carbon fibers and PTFE (polytetrafluoroethylene), the strength of the synthetic material is higher than that of rubber, so that the service life of the electromagnetic valve is prolonged; and at the same time, the sealing performance of the synthetic material is better than that of metal, so that the valve can be cut off and opened more rapidly and reliable. According to the electromagnetic valve, the closed seal ring is adopted, and the ring washer is arranged outside the seal ring to fix the seal ring in the sealing groove, so that the sealing is guaranteed to be good.
Description
Technical field
The utility model relates to a kind of guide electromagnetic valve, espespecially is applied in natural gas and the autoamtic compressed gas filling machine guide electromagnetic valve that unloads on gas equipment.
Background technique
Such valve that uses on filling machine at present mainly contains two kinds of forms: 1, pneumatic ball valve: price is high, reaction is slow; 2, solenoid valve: the sealed member of guide's part is metal or rubber.The sealing surface of solenoid valve main valve plug is groove face, and seal ring is angular cut, and sealing effect is poor, affects opening fast of valve.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of good sealing effect, the autoamtic compressed gas filling machine guide electromagnetic valve of long service life.
The utility model is a kind of autoamtic compressed gas filling machine guide electromagnetic valve, comprise valve body and spool, described spool comprises the solenoid valve main valve plug, solenoid valve is paid spool and is arranged on solenoid valve and pays needle on spool, closed seal ring is set in the seal groove of described solenoid valve main valve plug, and described seal ring arranges ring washer outward seal ring is fixed in seal groove.
Useful technique effect of the present utility model is:
1, sealed member of the present utility model is that the composite of carbon fiber and PTFE is made.The height of its strength ratio rubber has strengthened its working life, and its sealing is better than the metal simultaneously, make valve cut off and open more fast, reliable.
2, the seal ring that arranges in the sealing of solenoid valve main valve plug, past seal groove is opening, and sealing effect is poor.The utility model is closed seal ring, and seal ring arranges ring washer outward seal ring is fixed in seal groove, guarantees good seal.

Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, the utility model is a kind of autoamtic compressed gas filling machine guide electromagnetic valve, comprise valve body 1 and spool, spool comprises solenoid valve main valve plug 5, solenoid valve is paid spool 4, is arranged on solenoid valve and pays needle 7 on spool, and valve body arranges suction port, air outlet and gas channel A, the end of gas channel A connects suction port, the left side cavity of the other end connected electromagnetic valve main valve plug 5.Solenoid valve main valve plug 5 axially arranges gas channel B, and the right side port of gas channel B is communicated with the air outlet, the left side cavity of left side port connected electromagnetic valve main valve plug 5, and needle 7 is axially corresponding also with this port sealing with the left side port.After electromagnetic valve coil 18 energisings, thereby spool 7 makes the left side port be communicated with the left side cavity of solenoid valve main valve plug 5 owing to breaking away from this end opening to left movement.
The solenoid valve main valve plug arranges seal groove in the position that is connected with valve body, and closed seal ring 16 is set in the seal groove of solenoid valve main valve plug, and described seal ring arranges ring washer 15 outward seal ring is fixed in seal groove.Described seal ring is that the composite of carbon fiber and PTFE is made.
During work, gas is after suction port enters, enter the left side cavity of solenoid valve main valve plug 5 by gas channel A, at the left side of solenoid valve main valve plug 5 cavity mineralization pressure, this pressure is pressed the solenoid valve main valve plug to the right, block the gas channel between suction port and air outlet, keep blocking-up gas directly to leak gas to the air outlet after suction port enters valve body.After electromagnetic valve coil 18 energisings, solenoid valve is paid spool 4 and is moved to the left under magnetic force, keeps needle 7 to be moved to the left, and makes needle 7 syringe needles break away from the sealing surface that it and solenoid valve main valve plug 5 form, the sealing of releasing to port on the left of gas channel B makes gas flow to the air outlet by gas channel B.At this moment solenoid valve main valve plug left side pressure drop, the solenoid valve main valve plug is moved to the left under the effect of solenoid valve main valve plug bottom pressure, opens the gas channel between suction port and air outlet, makes gas directly flow to the air outlet from suction port.After electromagnetic valve coil 18 dead electricity, solenoid valve is paid spool 4 and is moved right, drive needle 7 and move right, needle 7 is sealed the left side port of gas channel B again, the gas of the left side cavity of blocking-up solenoid valve main valve plug 5 flows to the air outlet from gas channel B.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvement and modification, these improve and modification also should be considered as protection domain of the present utility model.
