Description

Self-cleaning type automatic drain valve {SELF CLEANING TYPE AUTO DRAIN VALVE}

The present invention relates to a self-cleaning type automatic drain valve.

In general, an air cylinder using compressed air is installed in a vertical direction under the pipe to be kept dry. The air cylinder is closed when there is an internal pressure, and is opened when there is no internal pressure, and an auto drain valve has been used for discharging residual water or foreign matter.

1 is for explaining an automatic drain valve using a conventional cylindrical seat.

As shown in Figure 1, the conventional automatic drain valve (Auto Drain Valve) is a force acting on the upper seat (Seat; 100) downward from the upper surface of the seat (Seat; 100) when the inner pressure is applied When the force exceeded by the spring 130, the flow path is closed by pushing down the seat 100 and contacting the disc 120. In contrast, when there is no internal pressure, the spring 130 is reversed. The force overcomes the internal pressure acting on the upper portion, and the seat 100 moves upward to open the flow path, thereby making automatic drainage.

Compressed air always contains a certain amount of moisture, oil, and foreign matters, causing problems such as rust caused by moisture when the system is stagnant for a long time, and problems such as sticking and delay of operation due to solidification of oil and foreign matters. Deterioration of the function, the residual water in the pipe is difficult to maintain a clean state, because there are foreign substances due to rust, when using a conventional automatic drain valve (Auto Drain Valve) for its discharge (Seat; 100) and disc (Disc There is a problem in that when the foreign matter is sandwiched between the 120 is difficult to remove itself, even if the automatic drain valve (closure) is closed, the fluid is not completely closed.

According to an embodiment of the present invention, even if foreign matter is accumulated or accumulated between the groove seat and the disc in the state in which the groove seat of the automatic drain valve moves upward and the flow path is opened, the accumulated foreign matter is not reduced. The purpose is to provide a self-cleaning type automatic drain valve that can be removed by itself.

Self-cleaning type automatic drain valve according to an embodiment of the present invention is disposed in the valve body, the valve body constituting the valve body and moves up and down according to the internal pressure generated in the valve body to block the fluid or vortex At least one groove sheet is formed so that at least one groove is formed, a disk disposed below the groove sheet to contact or separate from the groove sheet to block the fluid, and disposed between the groove sheet lower portion and the upper portion of the disk to be grooved according to the internal pressure of the valve body. It includes a spring for operating the seat up and down.

Self-cleaning type automatic drain valve according to an embodiment of the present invention by forming a groove in the groove seat, the vortex phenomenon occurs as the fluid passes through the groove of the groove seat in the state that the valve is open for the internal fluid discharge of the valve, There is an effect to minimize the wearing or accumulation.

In addition, the self-cleaning type automatic drain valve according to an embodiment of the present invention is a foreign matter due to the vortex of the strong fluid passing through the groove seat where the internal pressure is generated even though the foreign matter remains without being discharged by the vortex phenomenon when the valve is opened. The effect can be effectively removed.

In addition, the self-cleaning type automatic drain valve according to an embodiment of the present invention has an effect of minimizing the occurrence of leakage when the fluid is pressurized by the groove formed in the groove seat.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. Specific details of other embodiments are included in the detailed description and drawings. BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and how to accomplish them, will become apparent with reference to the embodiments described in detail below with reference to the accompanying drawings. Like reference numerals refer to like elements throughout.

2 is for explaining the configuration of the self-cleaning type automatic drain valve according to an embodiment of the present invention, Figure 3 is for explaining a self-cleaning type automatic drain valve assembled according to an embodiment of the present invention, 4 is for explaining a groove sheet according to an embodiment of the present invention.

2 and 3, the self-cleaning type automatic drain valve according to an embodiment of the present invention may include a valve body, a groove seat, a disc, and a spring.

The valve body 210 may constitute a valve body. The valve body 210 may support the components of the valve and at the same time configure the valve body.

The groove seat 200 is disposed inside the valve body 210 and moves up and down according to the internal pressure generated in the valve body 210 to block the fluid or vortex a phenomenon. At least one groove may be formed to cause this. That is, the groove seat 200 may move downward when the internal pressure is generated in the valve body 210, and the internal pressure does not occur in the valve body 210. Otherwise it can move upwards. In addition, at least one groove may be formed in the groove seat 200 to block the fluid or cause a vortex. As a result, the flow path may be closed or opened to allow automatic drainage. Detailed description of the groove seat 200 will be described later with reference to FIG. 4.

The disc Disc 220 may be disposed under the groove seat 200 to block the fluid while being in contact with or separated from the groove seat 200. That is, when internal pressure is generated in the valve body 210, the groove seat 200 moves downward to displace the disc 220 disposed below the groove seat 200. Can be contacted. As such, when the groove seat 200 contacts the disc 220, the flow path may be closed.

The spring 230 is disposed under the groove seat 200 and the disc 220 so that the groove seat 200 is vertically positioned according to the internal pressure of the valve body 210. Can be operated. That is, when the internal pressure of the valve body 210 acts, the internal pressure acts downward on the groove seat 200 from the top surface of the groove seat 200 to spring the spring. Groove seat 200 may be pushed down at a time point exceeding the force by 230. In other words, when the internal pressure of the valve body 210 is generated, the groove seat 200 may be moved downward because the internal pressure is greater than the force of the spring 230.

In addition, when there is no internal pressure of the valve body 210, the groove seat 200 may be pushed up by overcoming the internal pressure acting at the top of the spring 230. In other words, if the internal pressure of the valve body 210 does not occur, the groove seat 200 may move upward because the internal pressure is smaller than the force of the spring 230.

 As such, the vortex phenomenon occurs while the fluid flowing in the circumferentially vertically downward direction of the groove seat 200 passes around the groove seat 200, and the generated vortex phenomenon is the groove sheet. At least one groove may be formed in the groove seat 200 to remove foreign substances while flowing between the 200 and the disc 220.

Referring to Figure 4, at least one groove may be formed in the groove seat (Groove seat) 200 according to an embodiment of the present invention.

Three grooves 201 may be formed in the groove sheet 200 at equal intervals of 120 °. This groove may be an angle of inclination.

As described above, three grooves 201 are formed in the groove seat 200 at equal intervals of 120 ° so that the fluid is discharged even when the groove seat 200 is opened upward due to the vortex phenomenon. Vortex phenomena can minimize the accumulation of foreign matter. Moreover, even if foreign matter remains between the groove seat (200) and the disc (Disc) 220 without the vortex effect of the fluid under atmospheric pressure, the effect is greater at the time when the self-cleaning type automatic drain valve is closed by internal pressure. Vortex phenomena occur in the pressure fluid of the foreign matter can be removed efficiently.

In addition, the width of the cross section A of the groove formed in the upper part of the groove seat 200 and the width of the cross section B of the groove formed in the lower part of the groove seat 200 may be different. That is, the lower diameter of the groove seat 200 may be larger than the upper diameter of the groove seat 200, so that the widths of the end surfaces A and B of the groove may be different.

In addition, the shape of the groove 201 formed in the upper part of the groove seat 200 and the groove 201 formed in the lower part of the groove seat 200 may be substantially the same and may be different in size. . That is, the shape of the groove 201 formed at the top or the bottom of the groove seat 200 may be substantially the same, and the size of the groove formed at the bottom may be larger than the size of the groove formed at the top.

As such, the groove of the groove seat 200 is substantially the same as the shape of the groove formed in the upper part of the groove seat 200 and the shape of the groove formed in the lower part of the groove seat 200. It can be manufactured easily.

In addition, since the cross-sectional area and the size of the groove formed in the upper part of the groove seat 200 are different from the cross-sectional area and the size of the groove formed in the lower part of the groove seat 200, the effect of the vortex development of the fluid under atmospheric pressure is not eliminated. In addition, the foreign matter remaining between the groove seat 200 and the disc 220 also has a vortex effect at the time when the internal pressure is applied, so that the foreign matter can be removed more efficiently.

As described above, since the groove 201 is formed in the groove seat 200, the compressed air always contains a certain amount of moisture, oil, foreign matters, etc. due to the characteristics of the compressed air, and thus, the system is caused by moisture when the system is stuck for a long time. It is possible to prevent problems such as rusting, component sticking and delay of operation due to solidification of oil and foreign substances. Therefore, it is possible to prevent deterioration of the device function.
