Description

[Detailed Description of the Invention] This invention relates to a water pump, and more particularly, to the insertion of a stop valve,
The present invention relates to a water 1', IFI, which is easy to extract and can completely shut off water for an extremely long period of time.

Water leakage must be easy to handle, and at the same time, it must have a structure that has complete water-stopping ability and can withstand long-term use. If the material is selected or the clearance is large, insertion and removal will be easy at first, but water leakage will increase over time. If the surface material is too flexible, the rubber may get chewed up and become difficult to remove, and groove-like marks that are difficult to recover will remain on one side of the surface material that is continuously pressed by the hydrostatic pressure when water is stopped. . This groove-like mark greatly reduces the water stopping ability when the water stop valve is inserted again. On the other hand, if a hard elastic material is used as the surface material of the stop valve and the clearance is made small, the water stop ability will be sufficient and the service life will be long. However, it is inconvenient to handle the fluid pipes and operation pipes so that they do not stick together.

In this way, there is a need for a water stop valve that can be easily inserted and removed, and that completely shuts off the water. It doesn't exist yet.

The present invention has been made in view of the above points, and its object is to provide a water lock in which filamentous bodies are densely grown on the surface of a water leak stop valve.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In the longitudinal cross-sectional view of water #110 shown in FIG. 2, a valve operating pipe 14 is vertically connected to the fluid pipe line 12 extending in the left and right horizontal directions. An operating rod 16 is located in the center of the valve operating pipe 14.
is inserted, and a cylindrical support 18 having a larger diameter than the operating rod 16 is fixed to the lower end of the operating rod 16. The lower part of the support 18 is formed by a cylindrical body 20 that is smaller in diameter by about /cm than the upper part of the support. The surface of the support body 18 is coated with an elastic surface material 22, which has a cylindrical upper part and a hemispherical lower part, and the upper surface of the hemispherical part abuts the lower end of the cylindrical body 20. The upper part of the elastic surface material 22 is fixed to the support 18 using a fastener 24 and an adhesive. A cylindrical closed internal space 26 is formed between the lower part of the support 18 and the elastic surface material 22. Elastic surface material 2
The cilia A are densely grown on the entire surface except for the upper end surface of 2, so that the cilia A are brought into close contact with the cilia A. The diameter of cilia A is, for example, 0.7 to 9.
It is as thin as 2 mm, and its length is approximately 2 mm. In the dense treatment, an adhesive made of epoxy resin or the like is applied to the surface of the elastic surface material 22 to a uniform thickness, and static electricity is applied to the elastic surface material to uniformly coat the cilia made of synthetic resin or rubber threads on the surface. This is done by adhering to and fixing with adhesive.

To explain the function of the water lock according to the present invention, the cilia provide elasticity in addition to the elasticity possessed by the elastic surface material, so sliding is performed extremely well, and the surface of both the elastic surface material and the conduit is smooth compared to the conventional one. Extremely good sliding movement is achieved even in areas where it was difficult to move under the mirror surface condition. It is easy to pull out as the cilia escape, so it can be pulled out with a small amount of force and does not leave any marks on the elastic surface material. In addition, even if there is a place where it is difficult to make close contact with the side surface of the pipe or with a foreign object on the outside diameter, the cilia migrate and fill that part, preventing water leakage. A water leakage prevention part is formed by a jelly-like substance of slime bacteria in the minute gap between the two. In addition, in the embodiment, as hydrostatic pressure is applied to the elastic surface material 22 when water is stopped, the sealed internal space 26 between the elastic surface material 22 and the support body 18 on the surface where water pressure is applied is compressed, and conversely, the internal space is compressed. This compressive pressure is transmitted to the other side surfaces and the bottom surface, and the elastic surface material 22 expands, so pressure acts in the direction that the inner surface of the fluid pipe 12 and the stop valve come into close contact with each other, and the more hydrostatic pressure is applied, the more the water stops. becomes complete. In this case, the cylindrical body 20 presses the elastic surface material 22 against the bottom of the fluid conduit 12 to prevent it from floating (3), and also functions as a stopper to prevent excessive deformation of the elastic surface material. The above water stop valve can be easily deformed and removed by applying a force slightly stronger than hydrostatic pressure due to the friction reduction effect of the cilia and the large elastic deformation capacity of the elastic surface material and internal space. . Moreover, in this case, even if the clearance of the water stop valve is made slightly larger, there is no decrease in the water stop ability at all, and the water stop valve can be easily removed. Even if a relatively hard elastic surface material is used to increase the service life and water-stopping ability, it is easy to remove, and both longevity and ease of use can be achieved. In addition, the elastic surface material and filamentous body expanded into a downwardly bulging shape prevent the floating part of the water stopcock from expanding from side to side and being pressed against the pipe wall. Note that if the thickness of the elastic surface material is too thick, the expansion will be too little, and if it is too thin, the durability will be impaired, so it is necessary to perform an optimal design taking into account the size of the internal space, etc. It can contribute to having

(4) In addition, the elastic surface material can be divided into upper and lower parts and fixed to the surface of the support respectively, and the elastic surface material can be fixed by providing grooves or a large number of ribs 28 with the lower ends of the elastic surface materials as intersection points. Water capacity can also be increased. In addition, for the drop type water P1, without requiring a hemispherical surface at the lower end of the elastic surface material, a slightly reduced diameter part is provided only in the middle of the support, or is not provided, and the diameter reduced part position is cylindrical. It is sufficient to apply an elastic surface material with a slightly enlarged shape corresponding to this. In addition, since the water stop valve according to the present invention does not require strict consideration of clearance issues, for example, when installing a water lock, abnormalities such as backfilling with a machine where soil should be backfilled by hand according to regulations can be avoided. Even if a situation such as deformation of the fluid pipe occurs due to construction, the surface material and the cilia on its surface adapt to the changes in the situation and a favorable condition can be achieved, unlike in the past. It will be done.

In this way, when using the water lock according to the present invention, even if a flexible elastic surface material is not used for the stopcock, the cilia always contain water, so the friction reduction effect makes insertion and removal as easy as a flexible elastic surface material. It also has the water-stopping ability of a hard elastic surface material, and eliminates the drawbacks of hard and soft elastic surface materials such as difficulty in insertion or incomplete water-stopping due to the cilia on the surface of the stopcock. Because the cilia protect the surface of the water stop valve, it maintains its elasticity and recovers quickly, and it adapts to the water stop area, so it exhibits superior water effectiveness and durability that can respond to various situations. The cilia also have a cleaning effect during insertion and removal, which is a very remarkable effect.

Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to these embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. It is.
