The technical field to which the invention belongs, the prior art, the content, the embodiments and the drawings are briefly explained) [明 玲 ^ 属 ># 员] Field of the invention The utility model relates to an electromagnetic water supply valve which can move a 5-moving diaphragm valve body by opening and closing a pilot valve of an electromagnetic chamber to open and close a valve port. Γ Prior Art 3 Background of the Invention In the past, as shown in FIG. 4, a known water supply valve is formed on the body 100 to form an inflow chamber 102 communicating with the water inlet 101 and an outlet 103 communicating with the outlet 10 of the water. The outflow chamber 104 is installed with a cylindrical valve seat 106 at a valve port 105 formed between the inflow chamber 102 and the outflow chamber 104, and a diaphragm 107 and a diaphragm plate formed by rubber are installed. A valve body 1009 formed by 108 is detachably provided on the valve seat 106 to open and close the valve port 105. In this water supply valve, a guide chamber 15 101 provided on the lower side of the wide body 109 in the figure and a guide hole 1 π of the machine outlet to 104 and a communication hole 112 connecting the inflow chamber and the guide chamber 110 are passed through. Diaphragm plate 108. Moreover, by energizing the electromagnetic coil 15, the piston 117 imparted with potential energy toward the upper part of the figure by the spring moves toward the lower part of the figure, and the guide hole 111 is opened, and the electromagnetic coil can be cut to 5 When energized, 20 moves the movable base 117 upward in the figure, so that the guide hole is closed. " In the "direction hole 111 is closed, because the inflow chamber 102 and the guide chamber 110 are connected through the communication hole 112, the pressure in the guide chamber 110 is equal to the water inlet pressure. By this water inlet pressure, the valve body 109 faces the figure. The upper part pushes up and abuts the valve I 106, while the valve port 105 is closed and cuts off the water flow from the chamber 102 to the outflow chamber 104. On the other hand, when the guide hole 111 is switched from the closed state to the open state, the water in the guide chamber 110 flows out through the guide hole 111 to the outflow chamber, and the valve body 109 in the figure is subjected to water pressure and the valve body 119 is pushed downward. Pressure. As a result, the valve body 109 is separated from the valve seat 106 and communicates with the inflow chamber 102 and the outflow chamber 104, and water can be passed from the inflow port 101 to the outflow port 103. In this way, when water flows from the inflow port 101 to the outflow port 103, the solenoid coil II5 is energized, and the guide hole 111 is closed by the piston 117, the water flows into the guide chamber 110 through the communication hole 112 through the communication hole 112 through the inflow chamber 102, The pressure rises rapidly, and the valve body 119 moves upwards in the figure in an instant and the diaphragm 107 abuts the valve seat 106. Moreover, the volume of water near the diaphragm 107 is compressed at the time of abutment, and the water pressure rises rapidly, and a pressure wave generated by the rise of the water pressure is repeatedly reflected between the diaphragm 107 and the end of the inflow chamber 102, that is, The so-called water hammer 15 phenomenon. In addition, due to the water hammer phenomenon, when the rubber piston 107 vibrates, the diaphragm 107 and the valve seat 106 are repeatedly opened and closed, and the water pressure continuously changes due to the change in the water flow rate, which causes the diaphragm. Problems such as poor water stop between 107 and valve seat 106. SUMMARY OF THE INVENTION 3 20 Problems to be Solved by the Invention The object of the present invention is to provide a solution that can solve the above-mentioned problems, and can suppress the occurrence of poor water stopping between the diaphragm valve body and the valve seat when the wide opening is switched from the open state to the closed state. Electromagnetic water supply. 6 200302909 发明 Description of the Invention Solution to the Problem The present invention was made to achieve the above-mentioned object, and it relates to an improvement of an electromagnetic water supply valve. The electromagnetic water supply valve has a body connected to an inlet of water. Formed by the outflow chamber and the outflow chamber that communicates with the water outlet 5 through the water flow restricting portion;-a cylindrical valve seat, which is provided at the valve port formed between the aforementioned inflow chamber and the aforementioned outflow chamber;-a diaphragm The type body is provided opposite to the valve seat and can open and close the valve port; a guide chamber is located on the opposite side of the valve body opposite to the valve seat; a terminal hole is connected to the inflow A chamber and the pilot chamber; a pilot hole provided in the aforementioned 10 valve body and connecting the pilot chamber and the outflow chamber; and a pilot solenoid valve is used to open and close the pilot hole. Furthermore, the valve body is provided with an i-th guide member, and when the guide hole is closed by the guide solenoid valve and the valve port is switched from an open state to a closed state, the valve body is moved to Before 15 of the valve seat, there is a gap facing the outer peripheral surface or the inner peripheral surface of the valve seat, and the gap is used to restrict the water flow rate from the inflow chamber to the outflow port to be smaller than that restricted by the water amount restricting part. Water flow. According to the present invention, when the valve port is in an open state, the flow rate from the inflow to the outlet flow at i is 20 flow rate restricted by the water volume restriction unit (hereinafter, referred to as the first restricted flow rate). Moreover, when the guide solenoid is switched from the open state to the closed state by the guide solenoid valve, water will flow from the inflow chamber into the guide chamber through the contact hole, whereby the water pressure guided to the inside will rise due to the water inlet pressure. Therefore, the valve body can be moved toward the valve seat. 200302909 发明 、 Explanation of the invention In this case, when the valve seat starts to face the first guide member, the water flow rate from the inflow chamber to the outflow chamber is determined by the distance between the valve seat and the first guide member. The gap is restricted to a flow rate smaller than the i-th restricted flow (hereinafter referred to as a second restricted flow). 5 Therefore, during the transition of the valve port from the open state to the closed state, 'the water flow rate from the inflow chamber to the outflow chamber is reduced from the i-th restricted flow rate to the second restricted flow rate, so the valve port can be closed. . Furthermore, by this, the pressure wave generated when the valve body abuts the valve seat is reduced, and the vibration of the valve body is reduced, so it is possible to suppress the stop generated between the valve body 10 and the valve seat when abutting. Poor water. In addition, even if the valve body vibrates during the abutment, the water flow rate from the inflow chamber to the outflow port is limited to the second limit flow rate by the gap, and the vibration amplitude of the valve body changes. Small, so it can quickly slow down the vibration of the valve body. It is also characterized in that the first guide member is formed so that the gap is separated by a predetermined distance and becomes a fixed interval. According to the present invention, when the _ and the first material member face each other between the predetermined distances, the water flow rate from the flow-through room to the flow-out room is limited to be smaller than the above-mentioned gap by the fixed interval. ; Fixed flow rate of the system. In this case, even when the valve body abuts the valve seat, even if the vibration of the valve body occurs, the flow rate of the water passing from the inflow chamber to the outflow chamber is fixed by the aforementioned gap ′. Therefore, it is synchronized with the vibration of the valve body, and the change of the water flow rate is suppressed. The water and dust will not continue to change, and the vibration of the valve body can be slowed down quickly. 20 200302909 发明. Description of the invention The first guide member is formed so that when the valve body approaches the wide seat, the interval becomes gradually narrower. According to the present invention, when the valve port is shifted from the open state to the closed state, if the valve body approaches the valve seat and the valve seat starts to face the front end of the 51st guide member, the valve seat and the first 1 The interval between the guide members will gradually narrow. Therefore, the water flow rate from the inflow chamber to the outflow chamber will slowly move from the first restricted flow rate to the second restricted flow rate, thereby suppressing the fluctuation of the water pressure of the inflow chamber. It is also characterized in that it has a second guide member for moving the valve body only in a direction facing the valve seat 10. According to the present invention, the direction of movement of the valve body is restricted by the second guide member, and when the valve port is closed, the valve seat and the first guide member can be surely opposed to each other. I: Embodiment 3 15 Implementation Modes of the Invention The first and second embodiments of the present invention will be described below with reference to FIGS. 1 to 3. Fig. 1 is an overall configuration diagram of the electromagnetic water supply valve in the first embodiment of the present invention, and Fig. 2 is a detailed diagram of the valve structure of the electromagnetic water supply valve shown in Fig. 丨, and Fig. 3 is the present invention Detailed drawing of the valve structure of the electromagnetic water supply valve in the second embodiment 20. First, a first embodiment of the present invention will be described with reference to Figs. 1 and 2. The electromagnetic water supply valve shown in FIG. 1 is used to control the water passing between the inlet 3 and the outlet 4 formed by the main body 2 and is adjacent to the inflow chamber 5 communicating with the inlet 3 to limit the amount of permeated water. The hole 6 (corresponding to the 200302909, the water amount restricting portion of the invention description) is formed with the outflow chamber 7 communicating with the outflow port 4. A yoke 8 is formed between the inlet 5 and the outflow chamber 7, and a valve seat 9 is fixedly installed at the valve port ^. Further, the diaphragm plate 12 interferes with a central hole u formed in the center of the diaphragm 10 formed of a soft material such as rubber, and the diaphragm valve 10 and the diaphragm plate 12 constitute a diaphragm-type valve body 13. In addition, the valve body 13 is provided with a guide $ 14 on the lower side in the figure, and a diaphragm hole 12 is provided with a guide hole 15 connecting the outflow chamber 7 and the guide chamber 14, and a communication hole 16 connecting the inflow chamber 5 and the guide chamber 14. . Further, the center of the piston 10 18 which is separated from the bright end guide valve seat 17 formed in the guide hole 15 and opens and closes the guide hole 15 is arranged on the center line of the guide hole 15 in a unified manner. The piston 18 is provided with potential energy toward the upper part of the figure by the spring 19, and the electromagnetic coil 20 is not energized. The piston 18 is moved toward the upper part of the figure by the force of the impulse 19 and abuts the guide valve seat 17, and the guide hole is Closed state (the state shown in the figure). On the other hand, when the electromagnetic coil 20 is energized, the 15 piston 18 resists the biasing force of the spring 19 and moves downward due to the leakage magnetic flux of the magnetic circuit formed around the electromagnetic coil 20, and the piston 18 is guided by the valve seat. 17 is separated and the guide hole 15 is opened. The pilot solenoid valve of the present invention is composed of a pilot valve seat 17, a piston 18, a spring 19, and a solenoid 20. 20 Next, the operation of the electromagnetic water supply valve 1 will be described. When the current to the electromagnetic coil 20 is cut off, as described above, the piston 1 $ abuts the guide valve seat 17 and the guide hole 15 is closed. Moreover, in this state, water flows from the inflow chamber 5 into the guide chamber 14 through the communication hole 16, and the water pressure in the guide chamber 14 rises to the water inlet pressure, and the pressure in the guide chamber 14 is higher than the outflow 10 200302909 发明, invention description room 7 within the pressure. As a result, the valve body 13 is pushed upwards in the figure, the partition plate 10 of the valve body 13 abuts on the valve seat 9 and the valve seat 9 is closed, and the water flow from the inflow chamber 5 to the outflow chamber 7 is cut off. On the other hand, when the electromagnetic coil is energized, as described above, the movable base 18 moves downward and is detached by the guide valve seat 17, and the guide hole 15 is opened. In this state, water flowing from the inflow chamber 5 through the communication hole 16 into the guide chamber 14 flows out through the guide hole 15 to the outflow chamber 7. Therefore, by the water pressure from the inflow chamber 5, the valve body 13 is pushed downwards in the figure. The valve body 13 is separated by the valve seat 9 and the valve port 8 is open. 7 through the water. Further, in the electromagnetic water supply valve 1, when the current to the electromagnetic coil 20 is cut off and the diaphragm 10 of the wide body 13 abuts against the valve seat 9, a rapid pressure change in the inflow chamber 5 generates a pressure wave and vibrates the diaphragm. 10, and in order to suppress the occurrence of a water-stop failure between the diaphragm 10 and the valve seat 9 due to the vibration, a first guide portion 30 (corresponding to an i-th guide member of the present invention) is formed in the diaphragm I5 10. Hereinafter, the function and effect of the i-th guide portion 3G will be described with reference to FIG. 2. The second image shows that the current to the electromagnetic coil 20 is cut off and the guide hole b is closed. The valve body 13 moves upward. The state on the way is closed,. When the valve body

When the valve 13 in the figure moves upward in the figure and the diaphragm ⑺ abuts the pedestal 9 ', the flow rate of the water passing from the inflow chamber 5 to the outflow chamber 7 is reduced from the i-th restricted flow rate to the aforementioned second restricted flow rate. The diaphragm ι〇 abuts the valve seat 9. In addition, the squeezing, μhh, the diaphragm 1 of the scorpion moon stand 13 〇 the water pressure variation within 5 when the machine is produced when it abuts the valve seat 9, and the diaphragm diaphragm vibration is suppressed.

In the state where the valve seat 9 and the first guide portion 30 face each other, even if the valve seat 9 is opened and closed by the vibration of the diaphragm 10, the water flow from the inflow chamber 5 to the outflow chamber 7 line can be limited to the aforementioned second limit. A fixed flow below the flow. Therefore, 'the flow rate of the water passing from the inflow chamber 5 to the outflow chamber 7 can be restrained from fluctuating in conjunction with the vibration of the diaphragm 10, whereby even if the vibration of the diaphragm 10 is generated, the water pressure will not continue to change, and This vibration can be slowed down quickly. 15 Also 'The first end portion 32 of the first guide portion 30 is formed in an R shape.

In addition, the R-shape system acts to move the valve body 13 upward in the figure and starts from the wide seat 9 and the first guide 30 to face the valve body 13 close to the valve seat 9 with a gap of d, and the valve seat 9 and the first The gap between the guide portions 30 will gradually become narrower. Therefore, when the valve seat 9 and the first guide portion 30 start to face 20, the water flow rate of the inflow chamber 5 to the outflow chamber 7 can be gradually changed from the aforementioned first restricted flow rate to the aforementioned second according to the R shape. Restrict traffic. Furthermore, 'by this', it is possible to prevent the rapid change of the water pressure flowing into the chamber 5 and to reduce the pressure wave generated when the diaphragm 10 abuts the valve seat 9, and to suppress the vibration of the diaphragm 10. Furthermore, by virtue of this R shape, it is possible to obtain the effect that the valve seat 9 12 200302909 玖 can be inserted inside the first guide portion 30. In addition, the diaphragm plate 12 is inserted into the inner side of the valve seat 9 to form a fin-shaped second guide portion 33 that restricts the movement of the valve body in the up-down direction in the drawing. The valve seat 9 and the first guide portion 30 will surely face each other. Next, a second embodiment of the present invention will be described with reference to FIG. 3. Furthermore, for the same structures as those shown in Figs. 丨 and 2, the same symbols are used and the description is omitted. The electromagnetic water supply valve in the second embodiment differs from the electromagnetic water supply valve in the first embodiment in that the structure of the valve 10 is different. Referring to FIG. 3, the valve body 40 in the second embodiment is the same as the valve body in the aforementioned yoke-shaped evil. 3, the diaphragm plate 43 is embedded in the center of the diaphragm 41 formed of a soft material such as rubber. The center point of the formation is formed. Furthermore, when the diaphragm 41 of the valve body 40 approaches the valve seat 9, the cylindrical shape of the Xia Bow I guide 50 (corresponding to the inner peripheral surface 51 of the valve seat 9 formed on the diaphragm M 15 20) To the first guide member of the present invention). Fig. 3 shows the same state as in Fig. 2 in a state in which the energization to the electromagnetic coil 20 is cut off and the valve holder 40 is moved upward. When the wide body 40 moves upward and the inner peripheral surface 51 of the valve seat 9 faces the first guide portion 50, the flow of water from the inflow chamber 5 to the outflow chamber 7 restricted by the water amount restriction hole 6 before 1 limit flow), through the valve seat 9 and the first! The preliminary distance g 4 ′ between the guides is limited to a flow rate smaller than the first restricted flow 1 (hereinafter referred to as a third restricted flow) by the gap e at a fixed interval. Therefore, the valve body 40 moves upward in the figure and the diaphragm 41 abuts the valve seat 9 13 200302909 玖, description of the invention Nissei, because the flow of water from the inflow chamber 5 to the outflow chamber 7 is reduced from the i-th restricted flow rate to the aforementioned Since the third flow rate is restricted, the diaphragm 41 can be brought into contact with the valve seat 9. Furthermore, as in the case of the aforementioned first embodiment, the fluctuation of the water pressure in the inflow chamber 5 generated when the valve body 40 abuts the valve seat 9 becomes smaller 5 ', and the vibration of the diaphragm 41 can be suppressed. In the state where the valve seat 9 and the first guide portion 5G face each other, even if the valve port 8 is opened and closed by the vibration of the diaphragm, the water flow rate from the inflow chamber 5 to the outflow chamber 7 is limited to the above-mentioned third restricted flow rate. Fixed flow. Therefore, it is possible to suppress a change in the flow of water passing from the inflow chamber 5 to the outflow chamber 7 in conjunction with the vibration of the diaphragm 41. Thus, even if the vibration of the diaphragm 41 occurs, the water pressure does not continue to change, and This vibration can be slowed down quickly. Also, the front end portion 52 of the first guide portion 50 is formed in an R shape similarly to the first guide member 3G in the j-th implementation, thereby suppressing the inflow when the valve seat 9 and the first guide portion 50 start to face each other. The water pressure in the chamber 5 changes rapidly at 15 speeds. In addition, in the first and second embodiments described above, although the end portions of the first and second guide portions 30 and 50 are R-shaped, the interval between the valve bodies 13 and 40 close to the valve seat 9 and the gap may be used. Denoted by d and e, the gap between the cymbal 9 and the i-th guide portion Chuan and Be 2 is a gradually narrow shape (such as an inclined shape). In addition, 20 = even if the shape does not have this shape, the effect of the present invention in which the vibration of the h membranes 10 and 41 can be quickly reduced when the valve is closed can be obtained. In addition, in the aforementioned i and second embodiments, the second guide structure # 33 is provided and the movement of _13, 40 is limited to the direction facing the seat 9 ', but even if the second guide member 33 is not provided In some cases, the effects of the invention 14 200302909 (ii) and the invention description can be obtained. Redundantly taking evil 1F, it is shown that the "1 blade guide", 50 is formed integrally at the partitions M_10, 41 ', but the diaphragm plate 12, and the second guide portion of the reading shape 3 3 > 5, 3 Lower end portion 70 (refer to FIG. 2 μ f has the same shape, and the inner peripheral surface of the lower end portion 7G outside the peripheral surface seat 9 has a gap and opposite, and the gap is used to restrict the flow from the inflow chamber 5 to the outflow chamber; The flow of water. This form is the first part of the bottom part of the effect of the present invention.
