Description

[Detailed description of the device] [Industrial applications]

In recent years, there has been a strong demand for equipment such as a misalignment adjusting device for piping equipment due to the need for building structures, construction methods, and the like. Especially for drainage and ventilation piping, there is a strong demand for pipe joints that meet these requirements.

[Prior art]

In response to this, flexible joints having a bellows structure made of a soft material such as rubber, a poly-based material, or a vinyl-based material have been widely used, and have a considerable use record. In addition, the flexible joint of the integrally molded bellows structure made of only metal material has flexibility, and it is used for drainage and ventilation, but it is also low in workability and flexibility, especially in connection with the connecting pipe. Due to the metal cylinder, the band tightening force is insufficient and the sealing performance is unreliable.

[Problems to be solved by the present invention]

However, as the flexible joint made of a soft material is used more and more, demands and regulations for non-flammable materials for fire prevention are increasing. At present, non-combustible countermeasures are handled by racking the non-combustible material such as steel plate or glass plate or the non-combustible material such as glass wool on-site after the completion of the flexible pipe joint construction. ing. However, there is a strong demand for flexible, non-combustible flexible joints that do not require on-site response because of the complexity of construction, increased construction costs, external appearance, and aesthetic problems, and this proposal has these misalignment adjustment functions. Moreover, it is intended for a flexible joint that is non-flammable.

Incidentally, there is naturally a strong demand for an inner flat shape, which is the basic technical structure of the drainage joint. However, the one made of a soft material has a bellows structure to provide a center misalignment adjusting function. It can be said that the current flexible joint with a bellows structure is not suitable for drainage joints. Some people point out that the joints for connecting to toilets, etc. that have drains of filth, etc. must be inner flats. Therefore, it is also possible to use an inner flat plate made of a soft material as a flexible joint. However, even if the material is a soft material, if the inner surface is a simple cylindrical shape, it deforms when external pressure for core adjustment is applied, there is almost no center misalignment adjustment function, and a flat shape is substantially It is not a flexible joint. This proposal also addresses the problem.

[0005] Furthermore, due to a request for the basic structure of the drainage joint having a flat inner surface, a 90 ° bent joint having a flat inner surface made of a soft material is used as a flexible joint for connection with a toilet bowl. However, even if it is made of a soft material, the inner flat structure has almost no misalignment adjustment function. In reality, there are many cases where connections are made in the “seri” state. The present proposal makes it possible to provide a misalignment adjustment function even for curved joints.

In the drainage facility, basically, the pressure inside the pipe is 0 pressure or a slight pressure. Flexible joints made of soft materials are also made on the premise of this, and the pressure resistance function is within a slight pressure, and the usage conditions and usage range are limited. For this reason, pressure may be generated in the pipe for some reason, or the pipe may be used in a place with pressure, which may cause continuation due to water leakage or the like. The purpose of this plan is that it can be used even under some pressure.

In addition, a flexible joint made of a soft material exposed and connected to the toilet room such as a P-type toilet bowl is anxious about discoloration, deformation, and secular change. In addition, in the use process after the equipment, for example, when wiping with a detergent, cleaning agent, etc., the material is only a soft material, and there is no concern about discoloration, deformation, or surface cracking. The present proposal can also solve this point.

[Means for Solving the Problems]

[0008] Two short pipes made of a metal plate are covered with semicircular collars (1) and (1 ¹ ) that are concentric circles in which opposing pipe ends are expanded in a trumpet shape and one is covered on one side. The left and right ends of the joint of the present invention, which are formed as a single body by overlapping and connecting with each other, are provided with sockets for connecting pipes whose inner diameter is the outer diameter of the connecting pipe. Fig. 2 shows that the receiving inner cylinder (3) is attached to the inner diameter of the receiving opening (5) by a soft soft material such as soft vinyl chloride, rubber or poly-based material. .

FIG. (1) shows the inner joint (4) made of a soft material such as soft vinyl chloride, rubber, or a poly-based material mounted in the inner diameter of the joint of the present invention. The inner cylinder (4) can be molded separately by blow molding, injection molding, compression molding, or the like, and can be fitted into the joint of the present invention, or the inner cylinder (4) can be formed by blow molding or injection molding using the joint of the present invention as an outer mold. , Can be easily lined.

FIG. 4 shows an example in which a plurality of flanges are provided for polymerizing connection, but the short tube positioned in the middle part is polymerized and connected with the opposite semicircular flanges as left and right semicircular flanges. Be one.

[00011] Fig. 3 shows that the tip of a concentric collar that is formed at the end of the tube is overlapped with one another so that one side is covered with the other, which is a cross section of the collar part that is diagonally cut. It is a joint of the present invention that has a 90 ° bend as a basic shape.

The receiving opening (5) is provided with a longitudinal slit.

[00013]

[Action]

[00014] The inner cylinder (4), which is mounted and formed within the inner diameter of the joint of the present invention, has a metal outer cylinder that serves as a guide for a bending bender such as a pipe, and is not deformed even if core adjustment or bending pressure is applied. , Absent.

The inner diameter shape of the joint of the present invention is different from that of the bellows structure and has a gentle shape without sharp irregularities and steps, which can meet the inner flat structure which is the basic structure of the drainage joint.

The ring-shaped concave portion at the base of the receiving opening (5) and in contact with the body has elasticity and elasticity in addition to a core adjusting function against vibration and pressure.

[00017] In the case of the band-tightening connection after inserting the connecting pipe, the longitudinal slits provided in the receiving port are pressed inward at the longitudinal slits, and the tightening force is higher and easier. Can be fully tightened.

[Effect of device]

In this way, since the joint of the present invention is made of metal, it becomes a non-combustible joint, which eliminates the need for on-site correspondence and on-site construction as a non-combustible measure.

Since the collar and the collar, which are concentric circles, are superposed and connected, the core can be adjusted and the angle can be changed, and the non-combustible and misalignment adjusting function can be adjusted to adjust the misalignment in the connection between the pipes. It has a variable angle non-combustible joint. With respect to the superposition of the semi-circular brim formed in the body, the angle can be changed with one configuration, but the core adjustment cannot be performed. Therefore, two configurations are the main components of the joint of the present invention.

By increasing the number of collars to be overlapped and connected in the joint body, the variable angle becomes large and the direction becomes free. FIG. 4 shows an embodiment of the joint of the present invention in which a plurality of collar portions for superposition and connection are formed.

FIG. 3 shows the 90 ° joint according to the present invention. If the basic shape is a curved joint, the angle can be changed even though the joint is a curved joint. Of course, the straight-line joint of the present invention described in the preceding paragraph can also be changed in angle to 90 ° with a single joint if it has a plurality of overlapping connections, but it is possible to change the angle for a construction point requiring a small bending angle. It can be said that the joint has an insignificant effect on construction.

[00022] Not a core misalignment adjuster due to the bellows structure of the flexible pipe joint of the soft material,

As explained in [Operation], since the inner surface is flat, it also meets the technical basic structure of the inner flat, which is the technical basic structure of pipes and joints, and is suitable for non-combustion and misalignment adjustment. In addition, it is also optimal as a toilet fitting.

The structure of the joint of the present invention is made of metal, and the pressure resistance thereof is incomparable to that of the soft material flexible joint, and

Coupled with the high tightening force of the band described in [Operation], the range of operating conditions for the pressure inside the pipe is greatly expanded, and the anxiety and accident due to the pressure inside the pipe are eliminated.

Since the main body is a metal cylinder, there is no fear of discoloration, cracking, deformation, etc., over time.

In the case of the receiving inner cylinder (3) system, a normal packing or a ◯ ring is mounted between the overlapping collars, as shown in FIG. 1, when the inner cylinder (4) is mounted. Does not require the packing of the overlapping joints of the short tubes.

[000226] Fig. 5 shows that the inner joint (4) is made to project from the joint body without making one side of the joint of the present invention a receiving port, and has a diameter on the outer periphery of the protrusion that fits the inner diameter of the connecting pipe. If the shape is such that a lip is provided, it can be connected to the inner diameter of the drain pipe buried in the floor and wall.

[Correction content] [Detailed description of the device] [Industrial applications]

In recent years, due to the necessity of building structure, construction method, and the like, there has been a strong demand for a pipe facility that has a misalignment adjusting function and an elastic material. Especially for drainage and ventilation piping, there is a strong demand for pipe fittings that meet these requirements.

[Prior art]

In response to this, flexible joints having a bellows structure made of a soft material such as rubber, poly-based material, and vinyl-based material have been widely used, and have been used considerably. In addition, a flexible joint with an integrally molded bellows structure made only of metal material is also flexible and is used for drainage and ventilation.However, since it is integrally molded, it has low workability such as bending work and flexibility. Even when connecting to a connecting pipe, it is said that there is a problem that the band cannot be fully tightened due to the metal cylinder, and the sealing property is not reliable.

[Problems to be solved by the present invention]

However, while the flexible joints made of soft materials are used more and more, demands and regulations for nonflammable materials for fire prevention are increasing. Currently, at locations where non-combustible measures are required, after flexible pipe joints made of soft material have been completed, metal plates such as steel plates or non-combustible materials such as glass wool are racked at the site, and soft material joints are used in some places. In order to do so, we are responding by changing the structure of the building. However, there is a strong demand for flexible, non-combustible flexible joints that do not require on-site support because of the complexity of construction, increased construction cost, appearance, and aesthetic problems. It is intended to be a flexible joint that is both durable and non-flammable.

The demand for an inner flat shape, which is the basic technical structure of the drainage joint, is naturally strong. However, the soft material has a bellows structure to provide the function of adjusting the misalignment. It can be said that the flexible joint with the bellows structure is not suitable for the drainage joint. There is also a tendency to point out that the joints for connecting to toilets, etc., which have wastewater such as filth, must have a flat inner surface. Therefore, the one with a flat inner surface made of a soft material is also used as a flexible joint. However, even if the material is a soft material, if the inner surface is a simple cylindrical shape with flats, it will deform when external pressure for core adjustment is applied, there is almost no center misalignment adjustment function, and a flat shape is flexible. Not a joint. This proposal also addresses the problem.

Further, due to the requirement of the basic structure of the drainage joint having a flat inner surface, a 90 ° bent joint having a flat inner surface made of a soft material is used as a flexible joint for connection with a toilet bowl. However, even if it is made of a soft material, the inner flat structure has almost no misalignment adjustment function. In reality, there are many cases where connections are made in the “seri” state. The present proposal makes it possible to provide a misalignment adjustment function even for curved joints.

In the drainage facility, basically, the pressure inside the pipe is 0 pressure or a slight pressure. Flexible joints made of soft materials are also built on the premise of this, and the pressure resistance function is within a slight pressure, and the usage conditions and usage range are limited. Therefore, for some reason, pressure may be generated in the pipe, or the pipe may be used in a place with pressure, leading to accidents such as water leakage. The purpose of this plan is that it can be used under some pressure.

In addition, flexible joints made of a soft material exposed and connected in the toilet room, such as those for P-type toilets, are anxious about discoloration, deformation, and other secular changes. In addition, in the use process after the equipment, for example, by wiping with detergent, cleaning agent, etc., the anxiety of discoloration, deformation and surface cracking phenomenon cannot be wiped out because the material is only a soft material. The present proposal can also solve this point.

An important component of the joint has a structure of a connecting method with a connecting pipe. The methods are roughly classified into one, a connecting pipe receiving method in which a connecting pipe is provided with a receiving opening for inserting the connecting pipe into the inner diameter of the joint, and one is an inserting method in which the joint pipe end is inserted into the inner diameter of the connecting pipe. In either case, there are few joints with conventional metal materials that allow ventilation, variable angles for drainage, and adjustable cores.

[0002] As mentioned above, there is a problem with the method of connecting the connecting pipe with the variable angle and core adjustable joints for ventilation and drainage by using a metal material, and the present invention is easy and reliable in connection method and structure. , Is devised together with the main body.

[Means for Solving the Problems]

Semi-circular flanges (1) and (1 ¹ ) having concentric circles are formed at opposite ends of two short tubes made of a metal plate, and one of the semi-circular flanges is covered on one side. A main body part that is formed by superimposing and connecting in a shape, and a connecting port (12) for connecting by connecting a connecting pipe to the left and right ends of the main body part. The connection method with the connecting pipe is not necessarily the socket method, and there is also an insertion method, which will be described later.

The receiving inner cylinder (3) is configured to be mounted in the inner diameters of the receiving port (12) at the left and right ends by using a soft material such as soft vinyl chloride, rubber, or a poly-based material.

An O-ring packing (11) is mounted between the overlapping portions where the semi-circular collars that are concentric circles are superposed and connected to be integrated.

[0011] Fig. (3) shows the inner joint (4) made of a soft material such as soft vinyl chloride, rubber, or a poly material in the inner diameter of the joint of the present invention of the preceding paragraph. The inner cylinder (4) is formed by blow molding, injection molding, compression molding, or the like, and is separately molded, or the inner cylinder is formed by blow molding or injection molding using the joint of the present invention as an outer mold. The molding can also be easily lined.

Although FIGS. 1 and 2 are provided with a plurality of flanges for polymerizing connection, they are examples, and the short tube located in the middle part is a semi-circular flange on both the left and right sides and is polymerized with the opposing semi-circular flanges. And become one.

FIG. 4 shows a structure in which the tip end of a flange that is a concentric circle to be formed is formed by integrally cutting the flange portions of the shape in which the cross section is cut obliquely so that one side covers one side. The joint of the present invention, which has a bend as a basic shape, is a 45 ° bend joint if the tip of the collar is cut at an angle forming a 45 ° bend joint and is polymerized and connected.

A flange (7) is formed at the tip of the receiving port connecting port where the connecting port is inserted, and the inner diameter of the receiving port connecting port is the outer diameter of the connecting port. A nut (8) externally threaded on the outer circumference with the tip diameter of 7) as an approximate diameter is mounted in contact with the collar (7), and the outer diameter of the connecting pipe is the inner diameter on the outer side sandwiching the collar (7). The ring packing (6) is attached, the connecting pipe outer diameter is the inner diameter, and the cap nut (9) with the female thread that is screwed to the male thread provided on the outer circumference of the nut (8) and the ring packing (6) are built-in. When the nut (8) is screwed and tightened in this manner, the pressed ring packing (6) serves as a connection port having a sealing function as well as a function for securely holding the connection pipe.

A socket connection port having a plurality of longitudinal slits (2) provided on the outer periphery of the band attachment portion of the socket connection port (12).

A ring packing having a gap for inserting and scissoring the tip of the main body portion at the tip portion and a plurality of annular lips having different diameters on the outer circumference, and having an inner diameter close to the outer diameter of the main body portion Of the body (10) is inserted into the gap of the ring packing (10) at the tip of the body, and the scissors are used to adjust the angle.

The end of the main body having an outer diameter to be inserted into the inner diameter of the connecting pipe (13) is inserted into the inner diameter of the connecting pipe (13), and the inner diameter of about half of the total length is taken as the outer diameter of the connecting pipe. A ring packing (5) with an inverted L-shaped cross section, whose inner diameter is the outer diameter of the body end, is attached by cross-linking to the outer diameter of the connecting pipe and the outer diameter of the body, and from the outer circumference of the attached ring packing (5), Variable angle ventilation and drainage joint insertion port that is connected by tightening the band (14) to connect with the connecting pipe.

[Action]

[0018] Although it is a joint made of a metal material, the joint can be changed in angle because of the main body structure of the collar that is concentric and is superposed and connected.

As shown in FIGS. 1 and 2, it is possible to change the angle as well as to adjust the core on a straight line by providing two overlapping connecting portions of the collar that are concentric circles. It can be taken big.

When the inner cylinder (4) is mounted and formed within the inner diameter of the joint of the present invention, the metal outer cylinder serves as a guide for a bender for pipe bending, and even if core adjustment and bending pressure are applied, the inner cylinder (4) ) Does not deform.

By fitting a soft material such as soft vinyl chloride, rubber-based material, poly-based material, etc. on the inner diameter of the receiving port, even if it is a joint made of a metal material or a band is tightened from the outer circumference, The connecting pipe inserted into the receiving port can be tightened and retained. Depending on the type of connecting pipe, adhesive bonding can be used.

When the connecting pipe is inserted and the band is tightened with the band, the longitudinal slit groove provided on the outer periphery of the socket connection port easily pushes the longitudinal slit portion downwardly toward the inside. Therefore, the tightening force is higher, and the tightening can be done easily and completely.

The inner diameter shape of the joint according to the present invention is different from that of the bellows structure and has a gentle shape without sharp irregularities and steps, which corresponds to the inner flat structure which is the basic structure of the drainage joint.

[Effect of device]

[0024] In this way, the joint of the present invention made of a metal material becomes a non-combustible joint, and there is no need for on-site response or on-site construction as a non-combustible measure, which not only reduces construction costs and construction costs, but also improves the work finish. Its effects are immeasurable, such as appearance problems.

Since the collar and the collar that are concentric circles are superposed and connected, it is possible to adjust the core and change the angle, and to adjust the misalignment in the connection between the pipes. It becomes a non-combustible joint with a variable angle.

If the semi-circular collars formed on the body are superposed on each other, it is possible to adjust the straight line misalignment. The joint of the present invention is basically composed of two components.

[0027] If the number of collars to be overlapped and connected in the joint body is increased, the variable angle is correspondingly increased, and the joint can be freely rotated after connection.

[0028] Fig. 3 shows the 90 ° bent joint of the present invention. If the basic shape is a bent shape, even if it is a bent joint, the angle that has never existed in the past including soft materials It is a variable joint. In addition, the straight tubular joint of the previous section can also change the angle to 90 ° with a single joint if it is a joint having multiple overlapping connections, but the effect on construction is not necessary for the construction site where a small bending angle is required. It can be said that it is immeasurable.

[0029] Not a core misalignment adjuster due to the bellows structure of the flexible pipe joint of the soft material,

As explained in the section [Operation], since the inner surface is flat, it can meet the technical basic structure of the inner surface flat, which is the technical basic structure of the pipe and joint, and in addition to non-combustibility and misalignment adjustment, It is also optimal as a fitting for toilet bowls.

The structure of the joint of the present invention is made of metal, and the withstand pressure has a withstand pressure that is not comparable to that of the soft material flexible joint, and

Combined with the high tightening force of the band described in [Operation], the operating condition range for the pressure inside the pipe is greatly expanded, and there is no anxiety or accident due to the pressure inside the pipe.

Since the main body is a metal material, there is no fear of discoloration, deformation, cracking due to aging, or discoloration, deformation, cracking, etc. due to the use of detergents, cleaning agents, etc. in the process of use.

In the case of the receiving inner cylinder (3) system, a normal packing or a ○ ring is mounted between the overlapping collars. In the case of the inner cylinder (4) mounting as shown in FIG. No packing is required at the polymerization connection site of the mutual short tubes.

In the insertion method shown in FIG.

The connection port configuration described in [00017] is an insertion method in which the end of the joint is inserted into the inner diameter of the connecting pipe. Therefore, the main body joint is inserted, and after the length core is determined, band fastening work is performed, that is, expansion and contraction. You can have sex. Moreover, since the packing is adhered on the outer diameter of the connecting pipe, it is not necessary to deal with the slight difference in inner diameter depending on the type of connecting pipe.

Similarly, in the insertion method shown in FIG.

The connection port configuration described in [1] is an insertion method in which the end of the joint is inserted into the inner diameter of the connection pipe. However, the inner diameter difference slightly different depending on the pipe type of the connection pipe is a plurality of large and small diameter differences. The packing (10) having the lip of the above seals, that is, the large-diameter lip in the case of a connecting pipe having a large inner diameter, and the small-diameter lip in the case of a connecting pipe having a small inner diameter. Moreover, because of the insertion method, the insertion connection length can be freely adjusted and possesses elasticity.

In the socket system shown in FIG.

The connection port configuration described in [1] allows the length center of the pipe to be adjusted by the connection pipe side, and by tightening the nut and the cap nut, the ring packing installed is pressed, The connection with the connecting pipe and its secureness are perfect.

[0036] The fact that these connection port configurations of the inlet type and the insertion type have not only the construction characteristics such as the length and the core that can be adjusted, but also the number of types of joint lengths are not required. One length product will cover the required variety of certain length.
