- Valve device in No. 14299, Special Publication No. 57-40948
There is a float valve device etc. in No. In this literature technology, a valve body is provided in a casing to open and close a liquid discharge port, and a small liquid passage hole that communicates with the liquid discharge opening is bored in this valve body. The structure is such that the sub-valve body operated by an elevating rod can be freely moved towards and away from the valve body, and in this technology, the valve body descends while leaving the small liquid passage hole open, and closes the liquid discharge port.
Then, the small liquid passage hole is closed by the sub-valve body, thereby preventing the water hammer phenomenon, and
To facilitate the operation of the valve body and the sub-valve body. The purpose is to operate the valve body etc. without any power through the float. In addition, the float valve device has an on-off valve body that is fitted to the float so as to be able to move up and down, and the on-off valve body is raised and lowered twice as much via gear transmission and related mechanisms as the float goes up and down.
This technology moves the valve body up and down with a stroke twice as long as the float's vertical stroke to quickly drain water and return the water level to a certain level.

No. 59-126815 has an upward sleeve valve with a float. Its gist is that a cone valve seat is provided on the upper part of a fixed cylinder that discharges pressurized water in an upward direction, and has a conical surface and a horizontal annular surface that are spaced apart from the cylinder; It consists of a valve body that slides closely against the cylinder and moves up and down by a float. The effects are thought to be that the outflow water flows smoothly, there is no vibration in the valve body, and that the device can be made smaller.

Although it has the effect of operating in the same way, it has the following problems.

尚これらの問題点は、前記技術を本出願人が実
施した段階で初めて経験したところである。 Since the main parts are built into the casing, troubles such as dust clogging are likely to occur. In the valve device, fine dust etc. can get into the small gap between the guide frame and guide part of the casing and the valve body, making it difficult to slide. It is difficult to balance the initial breakthrough pressure from the sub-valve body with the lift pressure from the pressure receiving part, the discharge water tank becomes large because the jet energy cannot be reduced, and the structure for operating the valve rod etc. Since it is a pure mechanical structure such as a gear transmission mechanism, the structure is complicated, and although its operation is reliable, it lacks quickness. This is the first time the applicant has experienced this.

虞があると考えられるものである。 Furthermore, in the above-mentioned technical literature, since the flow is in an upward direction and the upward flow of the fluid is relatively weak, it is not sufficient to attract dust etc. that has entered between the valve body and the cylinder, and it is difficult to use agricultural water. It seems that this kind of waterway is not suitable for this type of waterway, which has a relatively large amount of garbage. Furthermore, the aforementioned technical literature states that the outflow water flows smoothly and there is no vibration in the valve body. However, the applicant believes that this effect is limited to a small amount and at low pressure, and that when the water pressure is over 1 kg, there is considerable vibration. In addition, water impinging on the guide surface (umbrella) of flowing water causes a large outflow energy loss, which may have the disadvantage of increasing the required diameter.Furthermore, if the discharged water is at high pressure and in large quantity, the energy that impinges on the umbrella-shaped guide is large. The vibrations are strong and the noise is high, and it is thought that there is a risk of disturbing the inside of the aquarium.

る。 Therefore, as already detailed, this technical document states that there is a risk that the energy colliding with the umbrella-shaped guide is large, resulting in strong vibrations and high noise, and that there is a risk that the inside of the aquarium may be disturbed. For these reasons, it seems that it cannot be used in cases of high pressure and large quantities, and the field of use is not limited.
また弁体とフロートが３点で連結されそれぞれ
４点で固定されており、振動等の原因によるフロ
ートの傾き等の虞があり、円滑なフロートと弁体
の連動ができないものである。 Furthermore, since the valve body and the float are connected at three points and fixed at four points each, there is a risk that the float may tilt due to causes such as vibration, and smooth interlocking between the float and the valve body is not possible.
更に導入管と円筒状弁体との間には、封水部が

る。 Furthermore, since there is no water seal between the introduction pipe and the cylindrical valve body, and because the valve body slides, there is naturally a slight amount of water between the introduction pipe and the valve body. There may be problems such as the possibility that a gap may be generated and dirt or the like may enter the gap.

A discharge port is provided at one end of the lower part of the casing having an inflow port,
As the fluid flows downward from above,
A chevron-shaped valve seat is provided at the tip of the discharge port via a valve seat rod, and a valve body that is fitted into approximately half of the casing that approaches and separates from this valve seat, and controls the elevation and descent of this valve body. A suspension member is provided on the outer periphery of the casing and straddles the casing, the base of which is fixed.

な移行が保証される。 In addition, in order to prevent dust clogging and to control the smooth lifting and lowering of the valve body, the casing has an inlet at the other end at the top and a discharge outlet at one end at the bottom. Flows downward and the fluid flows downwardly through a cylindrical valve body, and the casing is surrounded by a lubricating chamber filled with lubricating fluid.
Since the structure allows the upper part of the valve body to enter this lubrication chamber, it eliminates dirt clogging between the casing and the valve body, and also has the effect of attracting dirt, etc. that is between the casing and the valve body, and also prevents dirt from clogging. With the elimination of this, the penetration of the valve body into the lubrication chamber ensures a smooth transition of the valve body.

円錐状に突出している。"Effect" In Fig. 2, for example, the water level of a water tank (not shown)
As W 1 lowers to the specified position, float 12
As it descends, the swinging rod 13 sequentially swings using the support piece 15 as a fulcrum, leading to an ascending state as shown by the dashed line. As the swinging rod 13 swings, the suspension member 10 gradually rises, so that the cylindrical valve body 6 sequentially slides on the outer peripheral surface of the casing 1. As a result, the tip of the valve body 6 is attached to the valve seat 5.
The discharge port 2 is gradually opened. Therefore, water flowing in from the inlet 3 passes through the casing 1 to the outlet 2.
For example, the valve seat 5 is supplied to a water tank or the like, and since the valve seat 5 is shaped like a mountain (conical shape), the discharged water is dispersed in a cylindrical shape, and the energy of the discharged water can be reduced. Therefore, from low pressure to high pressure water,
Furthermore, it is possible to easily adjust and spray water from a small amount to a large amount into the air and underwater, and it also has the effect of dispersing and reducing the collision energy of water on the valve seat 5, and preventing vibrations even when high-pressure water is sprayed. be. Furthermore, since the valve seat 5 is mountain-shaped, its center protrudes conically.

が大きい。 In this way, in the present invention, the discharged water collides with the mountain-shaped valve seat 5, so the energy of the discharge is dispersed and
This has the effect of reducing vibration and noise generation. However, in the case of a conventional ordinary flat valve seat, the discharged water immediately collides with the flat valve seat, resulting in large amounts of vibration, noise, etc.

, and as a result, the amount of flowing water supplied into the aquarium and the rise during the closing process of the funnel 12 are characterized by being reduced. Furthermore, valve seat 5
It takes a long time to complete the blockage.

の供給が停止される。 As described above, in the present invention, as the valve body 6 closes, the water discharge area of the valve seat 5 decreases in a geometric progression, and the amount of water discharge decreases accordingly. This ensures a gradual increase in the water in the water tank and a gradual rise in the float, and based on this effect, the valve seat 5 is closed for a longer time, which is a factor that reduces water hammer. .
Furthermore, water can be released even from a small gap between the valve body 6 and the valve seat 5. Furthermore, inside the casing 1, the fluid flows downward, and the cylindrical valve body 6 ensures that the fluid flows downward, and the lubrication chamber 8 in which the casing 1 is filled with the lubricating fluid 9 is covered. In addition, since the upper part of the valve body 6 is allowed to enter the lubrication chamber 8, the gap between the casing 1 and the valve body 6 can be made extremely narrow. In addition, since the upper gap between the casing 1 and the valve body 6 is closed by the lubrication chamber 8, which serves as a water seal, no water can enter the lubrication chamber regardless of whether water is stopped or water is discharged. There is no intrusion of dust, and smooth lifting and lowering of the valve body 6 can be expected. Furthermore, when water is discharged, the downward force of the discharged water causes dirt and the like adhering to the inner wall surfaces of the casing 1 and the valve body 6 to flow downward, thereby causing the casing 1 and the valve body 6 to flow downward.
The self-cleaning action of the valve body 6 works, and in addition to eliminating clogging with dirt, the entry of the valve body 6 into the lubrication chamber 8 ensures smooth transition of the valve body 6. During the sliding process of the valve body 6, a lubricating film of water, oil, etc. is formed in the small gap A divided into the upper and lower parts between the valve body 6 and the casing 1, and the upper part of the valve body 6 is covered with a lubricating member. In addition to being able to smoothly enter the lubricating chamber 8 filled with oil 9, the valve body 6 moves up and down lightly. This allows the float 12 to be raised and lowered smoothly and quietly in accordance with the water level W1 . Then, water is sequentially supplied to, for example, a water tank, and when the water level W 1 rises to a predetermined position, the valve body 6 descends by the reverse operation of the above-mentioned operation, and is brought into contact with the valve seat 5a. When it comes into contact, the discharge port 2
is blocked, and the supply of water to, for example, an aquarium, water tank, waterway, etc. is stopped.

て減殺する効果がある。"Effects of the invention" As detailed above, the present invention provides a valve seat through a valve seat rod at the discharge port of a casing having an inflow port, and a valve body that can be moved into and out of contact with the valve seat portion of the valve seat. Since it is configured to fit into the casing, the float,
The valve body does not require any power through the suspension member, the swinging rod, etc., and has the effect of responding appropriately and smoothly in response to the rise and fall of the water level, and moreover, is guaranteed to be quick. The valve body is fitted into the casing of the downward flow method,
The structure is such that the fluid is discharged from the discharge port below the casing through the sliding movement of the valve body, and the fluid is also configured to flow downwardly through the cylindrical valve body, so that when water flows out, the casing and the valve body It has the effect of attracting water or dirt in the gap between the two, which helps eliminate the problem of dirt clogging, and has a self-cleaning effect. Therefore, it is ideal for waterways where there is relatively a lot of garbage, such as agricultural waterways. Furthermore, the upper part of the valve body is configured to allow entry into the lubrication chamber enclosed in the casing, so there is no resistance from water pressure when it rises, and water does not enter into the gap between the casing and the valve body. First, it is possible to prevent harmful effects such as expansion and twisting of the valve body due to water pressure. Furthermore, since the water is diffused and discharged through the valve seat, there is an effect of diffusing and reducing the jet energy.
