Description

Self-closing valve

The present invention relates to a magnetic valve, and more particularly to a magnetic valve having a hot and cold water control function.

In general, the self-closing valve is one of the water-saving water supply valve, the water supply time is fixed by the degree of the push button is pressed and the elasticity of the spring to return the push button to prevent unnecessary waste of water.

Autism valves are currently applied to general faucets, but are mainly used in public facilities such as toilets or showers.

1 shows autism valves which are mainly used in the related art, and reference numeral 100 denotes a valve housing. The valve housing 100 is formed with an inlet 200 and an outlet 300, respectively, and the valve body 400 is firmly coupled therein.

The valve body 400 is configured as a push button 410, a rod 420, a guide 430, a valve case 440, a first valve body 450, and a second valve body 460.

When the push button 410 is pressed on the valve body 400, as shown in FIG. 2, the rod 420 moves backward and slidably moves the second valve body 460 simultaneously with the first valve body 450. As the flow path is opened, the water flowing into the valve case 440 through the inlet 200 exits to the outlet 300 and is supplied with water.

Once the pressure pushing the push button 410 is removed in the state where water is supplied, the push button 410 is to be returned to its original position by the elasticity of the return spring 411. At this time, the push button 410 is fixed to the push button 410. The rod 420 is moved forward at the same time, and when the rod 420 is moved forward, the main flow path that is opened while the first valve body 450 axially coupled to the rod 420 is gradually moved forward is shielded. At the same time, a portion of the water flowing through the inlet 200 passes through the holes 463 and 464 formed in the ring 462 fixed to the second valve body 460 and the gasket 461. To be filled in the pressure chamber 471 formed by the 460 and the cover 470.

As the pressure inside the pressure chamber 471 expands due to the water filled in the pressure chamber 471, the first valve body 450 is pushed forward simultaneously with the second valve body 460. The main flow path is completely closed by the rod, and the rod 420 is further advanced than the first valve body 450 by the restoring force of the return spring 411 to return to the initial state as shown in FIG. 1.

In this way, the autism valve is to control the time that the push button 410 is pressed and returned so that the water supply can be made only for a predetermined time.

At this time, the movement distance of the self-closing valve is determined by the distance between the end of the adjusting screw 412 fastened to the push button 410 and the tip of the guide 430, and the time for reciprocating the movement distance is to supply water. You will decide the time.

However, such a conventional autism valve is generally provided as an auxiliary means of the water supply valve, it is common that the hot and cold water control valve is provided before the autism valve separately.

In other words, before adjusting the water supply amount, by controlling the cold / hot water control valve 500 separately provided as illustrated in FIG. 3, water of an appropriate temperature is guided to the autism valve and then operated by pushing the push button 410 of the autism valve. Since the water supply to the temperature is to be made, once the structure of the water supply valve is very complicated, there is a very uneconomical problem that the manufacturing cost is increased due to the increase in the number of parts required.

Therefore, the present invention was devised to solve the above-mentioned problems of the prior art, and an object of the present invention is to provide autism valves which greatly reduce the manufacturing cost and simplify the structure by allowing the hot and cold water adjusting function to be provided at the same time. have.

To be controlled.

Hereinafter, a preferred embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

As shown in FIG. 4, the present invention is largely composed of the valve housing 10 and the valve body 20 in the same manner as before.

However, in the present invention, the valve housing 10 is a tubular shape in which the inside is opened as a predetermined diameter to one side as before, and the valve housing 10 is adjacent to each other to the other end that is not opened to the hot water inlet 11 ) And cold water inlet 12 are formed.

The inside of the valve housing 10 of the hot water inlet 11 and the cold water inlet 12 allows the ring-shaped packing 14 to be inserted into the end of the empty space side while the spring 13 is coalesced therein.

The push button 22 is firmly coupled to one end of the rod 21 in the valve body 20, and the guide 23, the valve case 24, and the first end of the valve body 20 are moved from the push button 22 to the other end side. The valve 25, the second valve 26 and the cover 27 are successively axially supported, respectively.

In particular, the cover 27 and the valve case 24 of the configuration axially supported by the rod 21 are to be caught by the catching jaw 15 inside the valve housing 10 as shown in part A of FIG. The 27 and the valve case 24 are firmly fixed in the valve housing 10 while being pressed by the guide 23 screwed to the open tip side of the valve housing 10.

The push button 22 fixed to protrude outward from the valve housing 10 of the rod 21 allows the adjustment screw 22a to be fastened so that the screw forming portion protrudes rearward to one side of the plate surface. At this time, the operation length of the push button 22 is determined by adjusting the distance between the end of the screw forming portion projecting backward and the surface facing the guide 23 side. Meanwhile, the push button 22 and the guide 23 are elastically supported by the return spring 22b.

The rod 21 also has a flange 21a with an outer diameter extending outward toward the end inserted into the valve housing 10, while the first valve 25 and the inner side of the rod 21 are more inward than the flange 21a. The second valve 26 is screwed to each other in the axial direction, and as shown in Figure 5 in close contact with the second valve 26 along the inner circumferential surface of the cover 27 in the direction of the first valve 25 from the outside Gasket 26a, which is an airtight means for allowing the second valve 26 to slide, is coupled to the gasket 26a, and the ring is in close contact with the O-ring 25a on the side of the first valve 25 again. As the 26b is firmly coupled, the first valve 25 and the second valve 26 and the gasket 26a and the ring 26b are configured to be axially interlockable at the same time.

At this time, since the O-ring 25a of the first valve 25 forms a main water supply passage with the valve seat 24a of the rear end of the valve case 24, water supply is interrupted by the close contact and separation between them. Water flows into the valve case 24 through the passage, and the plurality of first holes are radially connected to the tubular valve case 24 so as to communicate with the outlet 16 of the valve housing 10 to the outer circumferential surface thereof. 24b) is formed.

And the outer space of the coupling portion of the first valve 25 and the second valve 26 to form a separation space with a predetermined length to face each other, the separation space is again covered by the ring 26b from the outside The second hole 26c is horizontally formed in the main surface of the second valve 26 so as to communicate with the spaced space, and the third hole 26d is radially formed in the ring 26b. It is to be formed as.

The space on one side formed by the second valve 26 in the cover 27 forms a pressure chamber 27a, and one end of the second hole 26c of the second valve 26 is formed in the pressure chamber 27a. ), Flushing spring (27b) is provided so that sliding movement is possible.

In addition, the cover 27 is formed with a diameter smaller than the inner diameter surface of the valve housing 10 to form a space spaced apart by a predetermined width on the concentric circle between them, of which a plurality of radially on the outer peripheral surface of the front end side of the cover 27 The fourth hole 27c is formed so that the fourth hole 27c is a main supply passage of water so that a larger hole size can be formed than the second hole 26c and the third hole 26d. Doing.

This valve configuration is almost the same as before.

However, the present invention has the most prominent feature in that the cold and hot water control function is provided at the same time in the above configuration.

In other words, as described above, the hot water inlet 11 and the cold water inlet 12 are formed in the valve housing 10, and the hot water inlet 11 and the cold water inlet 12 are rotatably coupled to the cover 27. It is opened and closed by the mixing plate 28.

As shown in FIG. 6, the mixing plate 28 has one end that is in contact with each end of the hot water inlet 11 and the cold water inlet 12 as a circular flat plate member, and the plate surface is symmetrical with each other on a concentric circle. The hole 28a is formed, but the water supply hole 28a has an inner diameter gradually reduced along the circumferential direction from one side to the other side while the end portions of each side adjacent to each other form an inner diameter with the diameters of the respective inlets 11 and 12. The water supply holes 28a on both sides of the bar shape are formed in radii that can communicate with the hot water inlet 11 and the cold water inlet 12, respectively.

On the other hand, the cover 27 side end portion of the mixing plate 28 has a tubular shape penetrating the center of the cover 27 and is rotatably fitted with the cover 27, and the tubular connecting end 28b The cover 27 is tightly coupled to the airtight, and the connecting end 28b and the rod 21 are connected by the serration shaft 29.

That is, the serration shaft 29 is fixed to the end of the rod 21 by the joining means so as to prevent the screw loosening together with the screwed end of the rod 21, and the connecting end 28b of the mixing plate 28 It is connected to the configuration that is fitted by the serration combination.

At this time, the serration shaft 29 is formed such that the outer diameter of at least the outer circumferential surface positioned at the inner diameter portion of the second valve 26 is formed to be smaller than the inner diameter of the second valve 26 so as to have a smaller size. The bypass passage 27d is formed in a minute width between the shafts 29.

Meanwhile, the connecting end 28b of the serration shaft 29 and the mixing plate 28 may be made by spline coupling.

Looking at the action by the present invention configured as described above are as follows.

The present invention allows the water supply and water supply time to be adjusted according to the adjustment amount of the adjustment screw 22a while the water supply is made by the operation of pushing the push button 22, which has a function of the conventional water supply control autism It is almost the same as a valve.

Before operating the self-closing valve, the outside of the cover 27 flows inside the valve housing 10 and passes through the third hole 26d and the second hole 26c through the fourth hole 27c and the pressure chamber ( 27a) the first valve 25 is pushed forward together with the second valve 26 by the pressure generated by the inflow of water, so that the O-ring 25a at the first valve 25 side is at the valve case 24 side. The state of close contact with the valve seat 24a is maintained.

In this state, when the push button 22 is pressed, the rod 21 moves backward. As the rod 21 moves, the rod 21 positioned at the inner diameter side of the first valve 25 as shown in FIG. The O-ring 21b fitted to the outer circumferential surface of the 21 is spaced apart from the valve seat 25b of the inner diameter side of the first valve 25 so that the water in the pressure chamber 27a passes through the bypass passage 27d and the first valve 25. Flow through the inner diameter of the valve case (24).

When water in the pressure chamber 27a moves to the valve case 24, the pressure in the pressure chamber 27a gradually decreases, so that the rod 21 can be moved further by pushing the push button 22, and the rod 21 When the first valve 25 is pushed by the movement of), the O-ring 25a coupled to the outer circumferential surface of the first valve 25 moves simultaneously with the second valve 26, as shown in FIG. 8. The first hole of the valve case 24 while being spaced apart from the valve seat 24a of the 24 and eventually leading the water flowing through the fourth hole 27c of the cover 27 directly into the valve case 24. The water supply is made by discharging to the outlet 16 through 24b.

On the other hand, if the force held down by the push button 22 is removed, the push button 22 moves the rod 21 forward while trying to return to the original position by the elasticity of the return spring 22b. When the rod 21 is moved forward, the O-ring 21b coupled to the rod 21 comes into close contact with the valve seat 25b of the inner diameter surface side of the first valve 25 and thus the water supply through the bypass passage 27d. Will block the flow. The rod 21 continues to move forward while blocking the flow path on the bypass passage 27d, thereby forming the pressure chamber 27a at a lower pressure. Thus, the water passes through the third hole 26d and the second hole 26c. The second valve 26 is pushed forward by the water pressure of the water thus filled.

As a result, the return elasticity of the return spring 22b and the increase in pressure in the pressure chamber 27a move the first valve 25 and the second valve 26 to the front, so that the O-ring (the outer circumferential surface side of the first valve 25) When 25a) comes into close contact with the valve seat 24a of the valve case 24, the water supply is cut off.

This intermittent action of the water supply is performed in the same way through the conventional autism valve, and according to the present invention, according to the angle of rotating the push button 22 in the clockwise direction or the opposite direction separately from the interruption of such water supply, The amount of water is controlled so that the water at the proper temperature can be provided.

In other words, when the push button 22 is rotated to one side, the serration shaft 29 axially coupled to the rod 22 together with the rod 22 rotates, and the serration shaft 29 has a mixing plate ( Since the tubular connecting end 28b of 28 is serration-coupled, the mixing plate 28 rotates at a predetermined angle in conjunction with the serration shaft 29.

When the mixing plate 28 rotates, the amount of hot water and cold water guided by the water supply hole 28a formed on the mixing plate 28 and the hot water inlet 11 and the cold water inlet 12 overlaps with each other. It can be different.

Therefore, once the push button 22 is pressed to check the temperature of the water supply in a state in which water is made, the push button 22 is rotated by a predetermined angle in one direction and adjusted until an appropriate temperature is achieved.

That is, as illustrated in FIG. 9, the push button 22 is rotated toward the hot water side in a state in which the hot water and the cold water side inlets 11 and 12 are opened to the same size by the rotation operation of the push button 22. 10, the water supply hole 28a having a large inner diameter is positioned toward the hot water inlet 11, and the water supply hole 28a having a small inner diameter is positioned at the cold water inlet 12 so that hot water can be supplied at a higher temperature. On the contrary, when increasing the supply of cold water, it is only necessary to rotate the push button 22 in the opposite direction as shown in FIG.

In this way, the present invention makes it easy to control the hot and cold water with the control of the water supply by a simple operation of the push button 22 only.

That is, by simply pressing or rotating the push button 22, the water of the required temperature can be supplied in the required amount, thereby providing a very easy operation with saving water.

In addition, in the present invention, the packing 14 is brought into contact with the mixing plate 28 while being supported by the spring 13 without directly contacting the mixing plate 28 toward the hot water inlet 11 and the cold water inlet 12. Even if the packing 14 is worn out due to the constant friction, the spring 14 may always keep the packing 14 in contact with the mixing plate 28 to prevent frequent replacement of parts due to wear between the friction members.

In particular, the present invention can omit the valve body for controlling the cold and hot water as in the past, so as to reduce the purchase cost of the product together with the manufacturing cost to be more generalized.

As described above, the present invention provides a very convenient operation by allowing the hot and cold water to be adjusted freely by a simple operation of rotating the push button 22 together with the control of the water supply by pressing the push button 22. Will be provided.

In addition, the present invention can omit a separate hot and cold water control valve is very easy to lay out the overall structure of the water supply valve, it can provide the advantages of very low-cost manufacturing, assembly and productivity by the simplified structure. Will be.
