Automatic water supply valve device by water pressure

1 is a cross-sectional view of the water supply valve is closed in the present invention.

Figure 2 is a cross-sectional view of the open passage and the main passage in the present invention.

The present invention is a solenoid device operated by a sensor for detecting a human body or an object at the front end of a water supply valve device directly connected to a water cock valve, in particular, by moving the moving iron piece toward the fixed iron piece fixed in the solenoid to open the valve The hydraulic pressure inherent in the space portion of the intermediate body passes through the open sub-valve and at the same time the cylinder is related to the automatic water supply valve device by the water pressure so that the main valve can be opened while moving forward as the water pressure in the space decreases. .

The conventional water supply valve structure has a permeable body through which an object passes through the front end portion, a sensor and a solenoid are installed inside the water supply valve, and a fixed iron piece and a movable iron piece are inserted into an inner groove of the solenoid, and a movable iron piece is formed. Permanent magnets are installed on the outer periphery and springs are installed at the ends.

The conventional water supply valve device configured as described above uses a spring fitted to the end of the movable iron piece in order to increase the attachment ability between the fixed iron piece inside the solenoid and the movable iron piece inside the permanent magnet. In one state, the movable iron piece is moved to the fixed iron piece side by the elasticity of the spring, and the reverse current is always flowed to the solenoid. This results in the shortening of the battery life, and the elasticity of the spring decreases when the water supply valve is used for a long time, reducing the ability to attach the fixed iron piece and the movable iron piece, and leaving the valve useless. There has been a disadvantage that the opening and closing function of the.

Therefore, the present proposal is to solve the above problems by forming a permanent magnet directly in contact with the movable iron piece to increase the attachment capacity of the fixed iron piece and the movable iron piece inside the solenoid, so that the secondary valve can be opened smoothly. Instead of blocking the valve by applying a reverse current to the conventional solenoid, the sub valve and the main valve are shut off by the water pressure in the space inside the intermediate body of the water supply valve.

When described in detail below on the basis of the accompanying drawings as follows.

That is, the inner side of the solenoid 4 which is operated by the sensor 3 which detects through the permeable body 2 which passes through a human body or an object in the front end part of the water supply valve 1 which is directly connected to the water cock (not shown). In the case where the stationary iron piece 5 and the movable iron piece 5 'are installed, the rubber packing 7 is attached to the permanent magnet 6 provided on one side of the movable iron piece 5', so that the sub valve 8 is attached. A cylinder 12 having a penetrating axial hole 13 is interposed in the space 11a inside the intermediate body 10, which is opened and closed and screwed to the inside of the main body, and is interposed therebetween. Hemispherical rubber packing 14 is inserted into one side of the shaft core hole 13, and the cylinder 12 has a shaft core hole 13 and a through hole 13 'on the surface of the cylinder 12, and the hemispherical rubber packing 14 The reciprocating operation by the cylinder 12 inserted into the main body to open the main passage (G) inlet 21, which is not described above. No. 15 is a battery, 16 is a water inlet, F is sub-channel.

The present invention having such a structure will be described in more detail and the operation and effect thereof will be described as follows. That is, when the sensor 3 is sensed through the transmissive body 2 passing through the human body or an object, the solenoid 4 which has received the current of the dry ground 15 generates magnetic force and fixes the fixed iron piece 5 fixed inside. At the same time, the polarity of the moving piece (5 ') and the moving piece (5') are attracted to the attraction force, and at the same time, the permanent magnet (6) and the rubber packing (7) attached together with the moving piece (5 ') are solenoids (4). By opening the sub-valve 8 while moving to the inner groove, the hydraulic pressure of the space 11a inside the intermediate body 10 passes through the sub-valve 8 and exits the sub-path F, and at the same time the cylinder 12 ), The water in the space 11a is released to the sub-valve 8 at a high speed due to the hydraulic pressure difference, and the space 11a of the intermediate body 10 generates a momentary negative pressure more than that of the side passage F. . Therefore, the cylinder 12 inserted into the space portion 11a of the intermediate body 10 moves forward in the direction of the sub-valve 8, and the hemispherical rubber packing inserted into the rear end of the shaft center hole 13 of the cylinder 12 ( 14 is to move with the cylinder 12 to open the inlet 21 of the main passage G.

After that, even if the current supplied from the battery 15 is cut off, since the permanent magnet 6 is attached to the movable iron piece 5 'by the force of the magnet, the sub-valve 8 is continuously opened to reduce the power consumption. Will be. That is, the permanent magnet 6 attached to one side of the movable iron piece 5 'when the signal sensed by the sensor 3 operates the solenoid 4 to move the movable iron piece 5' to the fixed iron piece 5. And the rubber packing 7 is moved together so that the sub-valve (8) is opened so that water introduced in advance into the space (11a) is released to the sub-valve (8).

At this time, since the drainage hole of the subvalve 8 is larger than the inlet 13 'formed in the cylinder 12, the amount of water flowing out through the subvalve 8 becomes larger than the amount of incoming water. If the cylinder 12 is a stationary stationary body, it will be drained to the subvalve 8 by the amount of water that is received, but the cylinder 12 is inserted freely into one side of the space portion 11a, and more than the amount of water received. The cylinder 12 is moved to the space portion 11a by the amount of drainage, so that the hemispherical rubber packing 14 inserted at the rear end of the cylinder 12 is moved together with the cylinder 12 to inlet 21 of the main passage G. Open).

In addition, when the solenoid 4 is operated and the movable iron piece 5 'is moved so that the rubber packing 7 blocks the sub-valve 8, the water entering the inlet hole 13' of the cylinder 12 becomes the sub-valve. (8) can not escape through the space (11a) to continue to push the cylinder 12, the pressure is applied to the hemispherical rubber patch 14 inserted in the rear end of the cylinder 12 to push the cylinder (12) Is advanced in the opposite direction to block the inlet 21 of the main passage G.

As described above, when the sub-valve (8) is shut off when not in use, the reverse current flows to the solenoid (4) when the sensor (3) detects the same as the first time or through the transparent body (2) passing through the object. The polarity of the fixed iron piece 5 fixed to the inside and the polarity of the movable iron piece 5 'form the same polarity to push the permanent magnet 6 and the rubber packing 7 attached together with the movable iron piece 5'. The main valve (G) is shut off by moving the cylinder (12) in the opposite direction while gradually forming a hydraulic pressure in the space (11a) while simultaneously blocking the sub valve (8) while returning to the original state. Even if it is used for a long time, it is not opening or closing method using spring, so it doesn't break, and the life of the battery can be extended by solenoid acting only when opening and closing the sub-valve. It is a very useful design that can reduce the cost of materials because the spring is not used to increase the attachment ability of the fixed iron and movable steel.
