Abstract

The present invention relates to a direct acting on / off valve used for a bidet or a water purifier, and more particularly, a damper for reducing the noise generated when the plunger of the direct acting on / off valve having an integrated plunger and a diaphragm rises in contact with a poster. Instead of eliminating the plunger cap, the plunger moves up and down inside the plunger cap so that the plunger does not collide with the plunger cap even if the plunger cap is raised so that the noise is reduced by a simple configuration. It has a diaphragm with a vertical fold to reduce the amount of fluid contacting the diaphragm when the fluid flows in at low water pressure, thereby preventing the diaphragm from rising and preventing the outflow phenomenon occurring at low water pressure. The configuration is characterized by that.

Description

Direct acting type shout-off valve

The present invention relates to a direct acting on / off valve used for a bidet or a water purifier, and more particularly, to increase the plunger of the direct acting on / off valve in which the plunger and the diaphragm are integrated to reduce the noise generated while contacting the poster. Instead of removing one damper, the plunger cap is provided so that the plunger moves up and down inside the plunger cap so that the plunger does not collide with the plunger cap to reduce noise with a simple configuration. Instead, a diaphragm having a vertical folding portion is provided to reduce the amount of fluid coming into contact with the diaphragm when the fluid flows in at low water pressure, thereby preventing the diaphragm from rising, thereby preventing the outflow phenomenon occurring at low water pressure. It is about a structure to prevent.

In the prior art, as shown in FIGS. 1 and 2, the body 201 of the direct acting valve 200 is provided with an inlet hole 202 through which fluid flows in and a water outlet hole 203 through which fluid flows out. A diaphragm 204 is provided above the body 201 between the inlet hole 202 and the outlet hole 203 to turn the on / off valve 200 on and off, and the solenoid 205 on the upper portion of the diaphragm 204. Is fixed to the body 201 by the support 206, the support 206 is embedded in the mold coil 212, the post 211 is provided on the inner upper end of the mold coil 212 and the post 211 In the center of the rubber damper 210 was assembled, the reason is that the noise generated when the plunger rises and hits the post (211) and the configuration to absorb the noise to the damper 210 of rubber material in order to reduce the noise One side of the spring 209 is in contact with one side of the post 211, the damper 210 is assembled The other end of the spring 209 is plunged in contact with the plunger 207, but the entire length of the plunger 207 is not inserted into the mold coil 212, but a part is inserted and a part of the outside of the support 206 It is provided to protrude and provided in the form of a solenoid 205, the plunger 207 protruding out of the support 206 is assembled through the hollow portion of the plunger cover 208 in contact with the lower portion of the support 206, spring The other end portion of the plunger 207 supported by the 209 is inserted into the body of the diaphragm 204 to turn on / off the fluid introduced from the inlet 202 to be discharged through the outlet 203. Part of the plunger 207, the plunger cover 208 and the diaphragm 204, which are assembled outside of the support part 206, and the water outlet hole 203 when the support part 206 and the body 201 are assembled. It is a configuration that is inserted into the top of the assembly.

And the diaphragm 204 applied to the conventional on-off valve, as shown in Figure 3, having a thin and wide horizontal folded portion 204-1 to the left and right, the horizontal folded portion of the diaphragm 204 when ON-OFF As the 204-1 is folded and unfolded, the direct acting on / off valve 200 is configured to perform ON / OFF operation.

Here, when the diaphragm 204 descends to block the upper portion of the outlet hole 203, the valve 200 is turned off, and when the diaphragm 204 rises to the upper portion of the outlet hole 203 and falls off from the outlet hole 203. The valve 200 opens to be in an ON state for discharging the fluid.

Looking at the movement direction of the fluid of the conventional direct-acting valve, the on-off valve is usually carried by the post of the upper portion of the mold coil embedded in the support portion by the clamping force of the spring to push the plunger to the outside of the support portion is lowered by the plunger and the diaphragm It is OFF because it blocks the exit hole in one state.When fluid flows into the inlet hole, if the diaphragm blocking the exit hole on the upper side of the body generates a fluid pressure greater than the spring force, the diaphragm rises and the plunger rises. As the spring contracts, the diaphragm is separated from the outlet hole and the fluid is turned into the ON state.

However, since the horizontal folding portion provided in the diaphragm is wide and thin right and left, the contact area between the horizontal folding portion and the fluid is increased even though a small amount of fluid is introduced at low pressure. The horizontal folding part is easily folded, and even if a small amount of fluid flows in, the diaphragm easily rises to the upper part and the water hole is opened to open the water. There was this.

In addition, in order to reduce the noise caused by the contact between the post and the plunger, there was a configuration in which the damper was embedded in the post to absorb the noise. Since the damper was embedded in the post, the manufacturing process was complicated and the material cost increased due to the increase of components. .

The present invention is to solve the above problems, the plunger cap is provided in the plunger cap instead of removing the damper provided to reduce the noise generated when the plunger of the direct-acting valve opens and contacts the poster When the plunger is raised to raise the plunger to prevent the collision with the plunger cap to reduce the noise, and instead of the diaphragm having a horizontal fold portion, the diaphragm having a vertical fold portion is provided in the case of low fluid pressure It is an object of the present invention to provide a configuration that prevents the diaphragm from rising by reducing the amount of contact between the fluid and the diaphragm.

According to the present invention, the plunger of the direct acting on / off valve causes the plunger cap to move up and down inside so that the plunger does not collide with the plunger cap so that the noise can be reduced by a simple configuration, and the vertically folded portion It is equipped with a diaphragm which has the effect of preventing the diaphragm from rising easily by reducing the amount of fluid contacting the diaphragm when a low pressure fluid flows in, thereby preventing the outflow phenomenon occurring at the low water pressure. There is.

The present invention relates to a direct-acting on-off valve in which the plunger and the diaphragm are integrated in the on-off valve used for a bidet or a water purifier, etc. The detailed description will be described with reference to the accompanying drawings.

Figure 4 is an exploded perspective view of the direct-acting valve of the present invention, Figure 5 is an assembled cross-sectional view of Figure 4, Figure 6 is a cross-sectional view of the diaphragm of FIG.

4 and 5, the body 201 of the direct acting open / close valve 200 is provided with an inlet hole 202 through which the fluid is introduced and a water outlet 203 through which the fluid exits, A diaphragm 204 is provided above the body 201 between the inlet hole 202 and the outlet hole 203 to turn the on / off valve 200 on and off, and the support part 206 is provided on the upper portion of the diaphragm 204. Is a component that is assembled to the body 201, the support portion 206 is embedded in the mold coil 212, the inside of the mold coil 212 is provided with a groove size of the plunger can be inserted into the plunger cap 213 Is provided, one side of the spring 209 is in contact with the inner upper side of the plunger cap 213 and the other end of the spring 209 is in contact with the plunger 207, the entire length of the plunger 207 mold coil 212 Rather than being inserted into the configuration, a part is inserted and a part is provided to protrude to the outside of the support 206, the outside of the support 206 The plunger 207 protrudes through the hollow portion of the plunger cover 208 in contact with the lower portion of the support 206 is assembled, and the other end of the plunger 207 carried by the spring 209 is obtained through the inlet 202 ) Is a direct type that is inserted into the body of the diaphragm 204 to be turned on and off so that the fluid introduced from the outlet 203 is discharged through the outlet hole 203, and is assembled integrally, the plunger assembled outside the support portion 206 A part of 207, the plunger cover 208, and the diaphragm 204 are configured to be inserted into the upper part of the water outlet hole 203, that is, the flow path when the support part 206 and the body 201 are assembled.

As described above, in the present invention, the plunger 207 is inserted into the plunger cap 213, but only the spring 209 is inserted therebetween, and the diaphragm for turning the direct acting on / off valve 200 ON or OFF ( As the plunger 207 moves up and down in the plunger cap 213 according to the rise and fall of 204, there is no collision, and only the noise emitted during the folding and unfolding of the spring and the up and down movement of the plunger 207 is applied. Therefore, it is a configuration that can surely reduce noise with a simple configuration.

As shown in FIG. 6, the diaphragm 204 has a vertical folding portion 204-2 having a thin upper and lower shape rather than a conventional horizontal horizontal folding portion 204-1. , When the diaphragm 204 is folded and unfolded in the diaphragm 204 when the linear actuated valve 200 is turned on or off, the linear actuated valve 200 is turned on or off. Since the upper and lower thin vertical folding portions 204-2 have fluids flowing into the inlet hole 202, the amount of contact between the vertical folding portions 204-2 and the fluid is not easily folded, and thus the upper and lower thin folding portions 204-2 are not easily folded. Since the diaphragm 204 does not operate even if a fluid of a low pressure (small amount) flows in, the diaphragm 204 does not operate even when a low pressure (a small amount) of fluid is introduced, so that water extraction does not occur at low water pressure.

Here, when the diaphragm 204 descends to block the upper portion of the outlet hole 203, the valve 200 is turned off, and when the diaphragm 204 rises to the upper portion of the outlet hole 203 and falls off from the outlet hole 203. The valve 200 is opened to discharge the fluid, which is the same as the operation of the on / off valve.

Looking at the flow direction of the fluid of the direct-acting valve of the present invention, the on-off valve is a spring is inserted into the inner side of the plunger cap in the mold coil of the usual support portion and the plunger is in contact with one side of the spring by the holding force of the spring When the plunger is pushed out of the supporting part and the plunger is pushed out of the supporting part, the diaphragm integrally provided with the plunger keeps the lowered state and closes the exit hole. If a fluid that is larger than the spring force of the spring is introduced into the diaphragm blocking the ball, the diaphragm rises and the plunger rises. When the plunger rises, the spring contracts, and the diaphragm falls out of the water hole and the fluid exits through this gap. It is the configuration of the direct acting valve.

The present invention is a configuration that can be used in the industry for manufacturing a direct acting valve of the integral plunger and the diaphragm in the valve for use in bidets, water purifiers and the like.
