TECHNICAL FIELD

[0001] The utility model relates to solenoid valve field, concretely relates to an intelligent control solenoid valve. BACKGROUND

[0002] The medium, sealing material and other components in the solenoid valve can all become hard and brittle at low temperature, resulting in icing or leakage of the solenoid valve and loss of normal function. In particular, in some extremely cold environments, the freezing phenomenon of the solenoid valve will be intensified. Therefore, the selection, installation and maintenance of the solenoid valve in winter work are crucial.

[0023] To make the purpose, technical scheme and advantages of the utility model clearer and more intelligible, the utility model is further described in detail below in combination with specific implementation manners and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0024] As Figs. 1-3 shown, the utility model provides an intelligent control electromagnetic valve, which comprises a valve body 1, and the valve body 1 is sequentially provided with an inlet end seat 11 and an outlet end seat 12 along the medium transmission direction.

[0025] The upper part of the valve body 1 is provided with a valve cover 2, the upper part of the valve cover 2 is provided with a driving device 3, the output end of the driving device 3 is connected with a valve rod 4 penetrating into the cavity of the valve body 1, the outer part of the valve rod 4 is sleeved with a valve core 5;

[0026] The channel formed in the lower part of the valve body 1 is connected with a residual liquid end base 6, the cleaning mechanism comprises supporting rings 71 symmetrically arranged in the channel, the supporting rings 71 are clamped with supporting members 72, and the two supporting rings 71 are clamped with a gas bag member 73, the inside of the gas bag member 73 is penetrated with a gas pipe 75, and one end of the gas pipe 75 penetrating the outside of the valve body 1 is connected with a ventilation end base 74.

[0027] It should be noted that the channel near the outlet end base 12 above the residual liquid end base 6, when the valve core 5 in the valve body 1 blocks the medium transmission channel, the position of the valve core 5 near the outlet end base 12 is the rear, part of the medium is left near the valve core 5, the upper opening of the channel is concave structure, which is convenient for the residual medium to gather in the channel.

[0028] In this embodiment, the valve body 1 is improved, and the cleaning mechanism is added, when the solenoid valve is closed after use, the cleaning mechanism works, the residual medium first gathers in the channel along the concave opening, at this time, the gas bag member 73 discharges the gas in the inside through the ventilation end base 74 and the gas pipe 75, and the gas bag member 73 is shrunk, because the supporting member 72 in the supporting ring 71 is a "cross" structure, the gas bag member 73 does not exist in the axial direction between the two supporting members 72, and the radial direction is not in the discharge channel between the inner wall of the channel and the flow gap, the medium can be discharged to the outside along the gap, and the problem of residual medium is solved.

[0029] It can be understood that the gas bag member 73 is a deformation member, when it is inflated and expanded, the deformation surface is closely attached to the inner wall of the channel, the purpose is to seal the channel, and the sealing performance of the valve body 1 when transmitting medium through the inlet end base 11 and the outlet end base 12 is ensured.

[0030] It should be added that the traditional valve body 1 is a closed structure, when the pressure of the valve body 1 needs to be discharged, a pressure relief valve is usually added at the pipeline connected with the valve body 1, the pressure relief mode is manual control, in the pipeline system where the solenoid valve is installed in large quantities, the opening and closing of each pressure relief valve needs to consume a lot of energy of the line inspection personnel, and there is a deficiency, the design of the cleaning mechanism can clean the residual medium and discharge the pressure in the valve body 1 at the same time, and the tedious operation of the line inspection personnel manually discharging the pressure is solved.

[0031] The ventilation end base 74 is connected with a gas supply device outside, the ventilation end base 74 is inflated and deflated through the gas supply device, and then the deformation of the gas bag member 73 is controlled, and the gas bag member 73 connected with the ventilation end base 74 is opened and closed synchronously with the driving device 3, when the driving device 3 drives the valve core 5 connected with the valve rod 4 to be closed, the gas bag member 73 connected with the ventilation end base 74 starts to discharge the gas, and the cleaning channel is exposed to the outside, on the one hand, the residual medium is cleaned, and on the other hand, the pressure in the valve body 1 is discharged, and the intelligence of the solenoid valve is increased.

[0032] In another embodiment, the bottom of the residual liquid end seat 6 is provided with a convex edge, which is connected to an external storage tank; when the electromagnetic valve is transmitting a medium with danger, it is dangerous to directly discharge the medium outside the valve body 1, but in order to ensure that it can quickly clean the residual medium in the valve body 1, the convex edge at the bottom of the residual liquid end seat 6 is provided as a connecting structure, and the storage tank is clamped at the convex edge position. The discharged medium is collected through the storage tank, solving the problem of medium harming the surrounding environment.
