Description

[Detailed Description of the Invention] <Industrial Field of Application> The present invention relates to a collar mainly used in bathhouses and the like.

<Prior art> This type of conventional push-type faucet, such as the Jikosho
The valve shown in Publication No. 48-16208 is a valve that is screwed upward onto a valve plate mounting plate provided below a valve stem that vertically passes through the valve seat opening of a valve seat formed in the faucet body. A valve plate is attached using a hexagonal nut having a shape smaller than the seat opening, and coil springs placed above and below the valve stem push up the valve stem and press the valve plate against the lower surface of the valve seat to close the valve, When opening the valve, lower the valve stem using a presser foot placed above the valve stem,
The valve plate is moved downward from the lower surface of the valve seat so that water flows out from the water outlet. Therefore, when the valve stem rises to close the valve by operating the presser foot, the hexagonal nut first enters the valve seat opening as the valve stem rises, and then the valve plate hits the bottom surface of the valve seat and the valve is closed. However, since the valve stem suddenly rises due to the coil spring, the water around the hexagonal nut and between the lower surface of the valve seat and the upper surface of the valve plate is suddenly pressed against the lower surface of the valve seat, and the hexagonal Since there is a gap between the surroundings of the nut and the valve seat opening, the water hammer is struck by the impact of the water that is forced into this gap, producing a loud impact sound and the sound of the impact causing the faucet to turn off. The main unit and nearby equipment such as meters broke down, and the rust from the inside of the iron pipe fell off and mixed into the water, making it extremely unsanitary.

<Problems to be solved by the invention> The present invention was devised in view of the above-mentioned circumstances, and when the valve is closed, the valve is raised together with the piece holder by the coil spring and inserted into the valve seat opening. Due to the truncated conical shape of the upper part of the screw, the water in this area is not suddenly pressed against the lower surface of the valve seat, and the water flowing from the water passage hole to the valve seat opening is gradually stopped. Next, water was stopped by the outer periphery of the screw inserted into the valve seat opening, so there was no water hammering when the valve was closed. Since the attached piece holder is made to rise, the purpose is to provide a lock that can stably stop water.

<Means for Solving the Problems> The present invention forms a bridge holder support portion having a water passage hole below a valve seat provided with a valve seat opening in the valve body,
A packing is attached to the top surface of the bridge holder, which is slidably inserted into the bridge holder support, so as to contact the bottom surface of the valve seat, and the head of a screw screwed into the center of the top of the bridge holder The packing is fixed to the piece holder, and the upper part of the head is formed into a truncated conical shape so that the outer periphery of the head can be slidably inserted into the valve seat opening, and the piece is inserted into the vertical hole of the screw. Insert the vertical rod, place a coil spring between the bottom cover screwed into the lower part of the bridge holder support and the bridge, and place the lower end of the valve rod, which is slidably inserted into the lever body, against the upper end of the vertical rod of the bridge. It's like letting them touch each other.

<Operation> With the above configuration, when the valve closes,
Since the upper part of the screw that rises and is inserted into the valve seat opening is shaped like a truncated cone, it will not be hit by water hammer.

<Embodiment> The present invention is based on a piece holder support portion 5 having a water passage hole 4 below a valve seat 3 provided with a valve seat opening 2 in a valve body 1.
A packing 7 that comes into contact with the lower surface of the valve seat 3 is attached to the upper surface of the bridge holder 6 which is slidably inserted into the bridge holder support portion 5.
The packing 7 is fixed to the piece holder 6 by the head 9 of a screw 8 screwed into the center of the upper part of the head 9, and the outer peripheral part 10 of the head 9 is slidably fitted into the valve seat opening 2. The upper part of the part 9 is formed into a truncated conical shape 11;
A packing 13 is attached to the inner surface of the lower cavity 12 provided in the piece holder 6, and water intrusion gaps 16 and 1 are provided in the vertical hole 14 of the screw 8 and the hole 15 of the packing 13, respectively.
7, insert the vertical rod 19 of the piece 18, and place the piece 18 in the upper cavity 22 of the bottom cover 21 screwed into the lower part of the piece holder support part 5 through the packing 20.
When the piece 18 is raised by the coil spring 23 attached to the packing 13 and comes into contact with the packing 13, the upper end 24 of the vertical rod 19 is slightly protruded from the upper surface of the screw 8. The lower end 27 of the valve stem 26, which is movably inserted, is brought into contact with the upper end 14 of the vertical rod 19 of the piece 18, and
A handle 28 is attached to the upper part of the valve stem 26, and a water outlet portion 29 is provided on the opposite side of the water passage hole 4 of the bell body 1.

When the present invention is used in the first embodiment, the valve is closed and opened by operating the handle 28 as follows.

First, when the valve is closed, the handle 8 is not pressed by hand as shown in FIG. 13, the bridge holder 6 inserted into the bridge holder support 5 below the valve seat 3 of the valve body 1 also rises, and the upper surface of the bridge holder 6 rises. Since the packing 7 is in contact with the lower surface of the valve seat 3, the water passage hole 4
The water flowing through the valve seat opening 2 to the water outlet 29 is stopped, that is, the valve is closed, and in this case, the screw fixing the packing 7 on the top surface of the piece holder 6 The outer peripheral portion 10 of the head 9 of No. 8 is inserted into the valve seat opening 2.
Further, the upper end 24 of the vertical rod 19 of the piece 18 is attached to the screw 8.
It protrudes slightly from the upper surface of the , and its lower end 2
7 is pushed up to the highest position. Furthermore, in this case, the water that has passed through the water hole 4 and the valve seat port 2 and has flowed into the water flow port 29 enters the water intrusion gaps 16 and 17 around the vertical rod 19 of the bridge 18, and enters the bridge holder. An attempt to enter the lower space 12 at 6 is prevented between the piece 18 and the packing 13.

Next, when water is to flow out from the water outlet 29, the handle 28 is pushed down against the tension of the coiled spring 23 as shown in FIG.

In such a case, first, the upper end 24 of the vertical rod 20 of the piece 18 is pushed down by the lower end 27 of the valve stem 26, so that the piece 18 moves downward from the packing 13 and enters the water intrusion gaps 16, 17. The water and the water near the valve seat opening 2 enter the lower cavity 12 through the water intrusion gaps 16 and 17, and at the next moment, the lower end 27 of the valve stem 26 comes into contact with the upper surface of the piece holder 6, and the screw 8 The infiltration of water is stopped by blocking the vertical hole 14 of the
In that state, screw 8, packing 7 and piece holder 6
As a result, water from the water hole 4 passes between the truncated conical shape 11 of the screw 8 and the valve seat 3, enters the valve seat port 2, and flows out from the water flow port 29. .

Next, when the valve is closed and the pressure on the handle 28 is relaxed to bring it into the state shown in FIG.
The water in 2 rises through the water intrusion gaps 16 and 17 and is pushed out to the valve seat opening 2, and the piece 18
3, the piece holder 6 is pushed up, and the truncated conical shape 11 of the screw 8 gradually stops the water flowing from the water passage hole 4 to the valve seat opening 2, and ,
The outer periphery 10 of the head 9 of the screw 8 is inserted into the valve seat opening 2, and the packing 7 that has risen together with the piece holder 6 comes into contact with the lower surface of the valve seat 3 and is removed from the water passage hole 4 through the valve seat opening 2. The valve is closed with a device that completely stops the water flowing into the tank.

In addition, in the second embodiment of the present invention, as shown in FIG. Therefore, when the valve is closed, when the screw 8 rises and gradually stops the water flowing from the water passage hole 4 to the valve seat opening 2, the water flows through the tapered groove. 30, the passage of water is better than in the case where only the truncated conical shape 11 of the first embodiment is used. Therefore, it is preferable to use the second embodiment when the water pressure is low.

<Effect of the invention> As explained above, in this invention, screw 8
Since the shape of the upper part is formed into a truncated conical shape 11, even when the screw 8 rises when closing the valve, water between the lower surface of the valve seat 3 and the truncated conical shape 11 can be removed. without suddenly pressing against the bottom surface of the valve seat 3, as in
In addition, since water flowing from the water passage port 4 to the valve seat port 2 is gradually stopped by the truncated conical shape 11, water hammer does not occur. Therefore,
It does not generate impact noise, and since there is no impact, there is no damage to the main body 1 or nearby instruments such as meters, and the rust on the inner surface of the iron pipe does not fall into the water, making it quite hygienic. It has the effect of
