BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a hybrid valve, and more particularly, to a hybrid valve in which components for controlling fluid flow in a piping line are integrated to have a combined function.

BACKGROUND ART In general, piping for heating pipes, heat exchangers, and hot water boilers such as boilers and hot water distributors is provided with an opening / closing valve such as a ball valve to shut off or open the flow of the fluid or adjust the flow rate.

The ball valve is installed in a pipe through which a fluid flows, such as a heat exchanger, a water supply and a water heater, and interrupts fluid flowing in the pipe. The ball valve rotates on the valve seat provided inside the valve body, .

The ball valve has been developed in various forms according to need, such as manual or electric type.

On the other hand, it is necessary that the fluid flowing through the pipeline is filtered in a filtered state, and that the fluid inside the pipeline is periodically filtered due to the foreign matter not filtered during the filtration process and the generation of a foreign material inside the pipeline.

That is, when foreign matter such as sludge flows into the piping or sludge is mixed in the fluid flowing along the pipeline, the foreign matter, sludge, and the like are discharged through various piping components such as a ball valve, a calorimeter, Which may reduce the function of the ball valve or various piping components and shorten the service life of the ball valves or the various piping components. Therefore, a filtration structure for the fluid to transport the pipeline is required.

For this purpose, a strainer is installed in the pipeline for the purpose of filtering impurities such as foreign matter, sludge and the like to keep the pipeline clean.

The strainer has a function of filtering foreign substances contained in the fluid.

The strainer is composed of a mesh so that the fluid flowing through the pipeline always passes through the strainer so that the foreign matter is filtered through the mesh.

On the other hand, a check valve may be further provided on the pipeline.

The check valve is a one-way valve, and is a valve in which the fluid flow on the pipe is made only in one direction.

That is, when the fluid flows through the check valve, the fluid does not flow back by the check valve.

The pipeline components described above are installed in the pipeline to optimize fluid flow.

1, a ball valve 10, a strainer 20, and a check valve 30 are disposed in sequence on one piping line, whereby the fluid passing through the pipe line through the opening of the ball valve 10 Is filtered through a strainer (20) and then passed through a check valve (30).

However, as described above, the structure in which the respective parts are installed in one pipe has the following problems.

First, since the construction of the piping line becomes complicated, the mechanical fatigue of the piping line is increased.

Secondly, there is a problem that the construction cost is increased according to the manufacturing cost of each part, resulting in poor economical efficiency.

Third, as the construction of each part is carried out, the working air can be delayed, and there is a problem that convenience and efficiency in construction are inferior.

In particular, there has been a problem that the convenience of maintenance management is poor.

Fourth, since a plurality of joints are formed on one pipeline, there is a problem that leakage probability is high.

Fifth, since the components are disposed separately, there is a problem that efficiency is deteriorated due to expansion of construction depending on the extent of the work space.

It is to be understood that the words or words used in the present specification and claims are not to be construed in a conventional or dictionary sense and that the inventor can properly define the concept of a term in order to describe its invention in the best possible way And should be construed in light of the meanings and concepts consistent with the technical idea of the present invention.

Hereinafter, a hybrid valve according to a first embodiment of the present invention will be described with reference to FIGS. 2 to 4 attached hereto.

The hybrid valve is characterized in that the components having respective functions for controlling the flow of fluid in the piping line are integrally formed to have a complex function as one valve.

Accordingly, it is possible to simplify the structure, thereby improving the convenience and efficiency of manufacture and construction, and can be less restricted to the construction space.

The hybrid valve comprises a strainer assembly 100 and a ball valve 200, as shown in FIG.

The strainer assembly 100 serves to filter foreign matter contained in the fluid transferred along the piping line and constitutes one side of the hybrid valve.

The strainer assembly 100 includes a vertical tube 110, a mesh net 120, and a shield cap 130.

The vertical tube 110 provides a space for filtering the foreign matter of the fluid, and is provided in a direction perpendicular to the fluid flow.

At this time, the vertical tube (110) forms a space for the fluid to flow therein, and on both sides of the upper side of the vertical tube (110), an entrance (111)

That is, an inlet 111a through which the fluid flows into the space is formed on one side of the upper portion of the vertical tube 110, and an outlet 111b through which the fluid is discharged from the space is formed on the upper side of the vertical tube 110.

The lower portion of the vertical tube 110 forms an opening 112 for opening the space.

For convenience of explanation, the opening 112 formed in the lower portion of the vertical tube 110 of the strainer assembly 100 is referred to as a first opening.

The first opening 112 is a portion in which the mesh net 120 enters and exits and is configured to provide convenience in replacement or maintenance of the mesh net 120.

That is, since the lower portion of the vertical tube 110 constituting the strainer assembly 100 is opened and the mesh net 120 can be easily attached to and detached from the vertical tube 110 through the opened portion, It is possible to solve the inefficient problem of replacing the entire valve when the valve 120 fails.

A coupling piece 113 extending to both sides is formed at a lower end of the vertical tube 110 and a coupling hole 113a for coupling with a first shielding cap to be described later is formed in the coupling piece 113.

The mesh network 120 serves to filter out foreign substances from the fluid flowing into the space through the inlet 111a of the vertical tube 110 along the piping line and is provided in the vertical tube 110 space.

The mesh net 120 is of a mesh type so that foreign matter can be filtered, and is preferably formed in a shape corresponding to the space of the vertical tube 110.

At this time, the mesh net 120 has a size corresponding to the space of the vertical tube 110, and one surface thereof is preferably formed to be inclined.

That is, the mesh network 120 constitutes a surface corresponding to the inlet 111a and the outlet 111b of the vertical tube 110, and the mesh network 120 corresponding to the inlet 111a of the vertical tube 110, 2 and 4, the mesh network 120 is formed with a tilting network 121 inclined downward from the lower portion to the upper portion of the mesh network 120, and the outlet 111b of the vertical tube 110, And the other surface of the mesh network 120 corresponding to the mesh network 120 is formed by forming a close-up net 122 which is in close contact with the outlet 111b of the straight pipe 110. [

3 and 4, a space is formed between the inlet 111a of the vertical tube 110 and the gill net 121 of the mesh net 120. As shown in FIG.

The reason why the mesh net 120 is formed in the mesh network 120 is that the relatively large particles contained in the fluid conveyed along the pipe line are guided to the vertical tube 110 to facilitate the treatment of the foreign matter In order to make it possible.

Since the mesh network 120 blocks the entrance 111a of the vertical tube 110 when the gauze network 121 is not formed, foreign matter having a large particle size is clogged with the mesh network 120, It is not allowed to flow into the space of the pipe 110 at all, thereby causing a problem of clogging the pipe by being deposited on the pipe line.

Therefore, by forming the glowing mesh 121 on one surface of the mesh network 120, a space can be secured between the mesh network 120 and the inlet 111a on the space of the vertical tube 110, (110a) through the opening (111a) and can be filtered by the alumina (121).

The shield cap 130 shields the first opening 112 of the vertical tube 110 and is provided to be detachable to the coupling piece 113 of the vertical tube 110.

For convenience of explanation, the shield cap 130 for shielding the first opening 112 of the vertical tube 110 is referred to as a first shield cap.

On the other hand, the first shielding cap 130 is formed with a coupling piece 131 corresponding to the coupling piece 113, and the coupling piece 131 is formed with a coupling hole 131a corresponding to the coupling hole 113a.

Next, the ball valve 200 controls the flow of the fluid and constitutes the other side of the hybrid valve.

The ball valve 200 is integrally provided at an inlet 111a or an outlet 111b of the vertical pipe 110 and includes a pipe 210 forming a pipe and a handle 220 for opening and closing a pipe of the pipe 210 ).

At this time, the vertical pipe 110 of the strainer assembly 100 and the pipe body 210 of the ball valve 200 are connected to the piping line, respectively.

In this way, while the hybrid valve is connected to the piping line, the pipeline line is opened through the rotation of the handle 220 of the ball valve 200, and a pump (not shown) of the pipeline line is operated to transfer the fluid.

At this time, the fluid flows into the space of the vertical tube 110 through the inlet 111a of the vertical tube 110, and the fluid flows into the space of the vertical tube 110.

At this time, the foreign matter having a large particle size is filtered by the gauze 121 of the mesh net 120, and the fluid exits through the mesh net 120 to the outlet of the vertical gas pipe 110.

At this time, the large and small foreign matter is filtered into the inside and the outside of the mesh net 120.

Thereafter, the fluid is transferred to the piping line along the pipe 210 of the ball valve 200.

On the other hand, when the foreign matter collection is saturated in the mesh net 120, the pump is stopped and the bolt is separated from the engagement piece 113 of the flared straight pipe 110 to separate the first shield cap 130 from the engagement piece 113.

Thereafter, the mesh net 120 is taken out through the first opening 112 to clean the spaces of the mesh net 120 and the vertical tube 110.

After the cleaning is completed, the mesh net 120 is inserted into the vertical tube 110 through the first opening 112 and then the first shielding cap 130 is inserted into the coupling piece 113 of the vertical tube 110, Lt; / RTI >

At this time, the opening / closing disk 323 is installed so as to rotate only in the advancing direction of the fluid.

That is, the opening / closing disk 323 is hinged so as to be rotated only by the water pressure in the direction in which the fluid advances.

The shield cap 330 shields the second opening 311 of the valve tube 310 and is detachably attached to the second opening 311.

For convenience of explanation, the shield cap 330 which is detachably attached to the second opening 311 is referred to as a second shield cap.

The second shielding cap 330 shields the second opening 311 of the valve tube 310 and serves to fix the check valve cartridge 320 in the valve tube 310.

The second shield cap 330 corresponds to the second opening 311 and includes a fixed guide bar 331 extending downward.

The fixing guide bars 331 are formed on both sides of the second shielding cap 330 and are preferably provided as a pair and correspond to both sides of the body 321 of the check valve cartridge 320.

That is, in the process of shielding the second opening 311, the second shield cap 330 having such a structure is inserted into the valve tube 310 through the second opening 311, The check valve cartridge 320 can be fixed within the valve tube 310 by closely contacting the body 321 of the check valve cartridge 320 to one side of the valve tube 310. [

The fixed guide bar 331 is interposed between the body 321 of the check valve cartridge 320 and the inner surface of the neck portion 311a of the second opening 311.

At this time, it is preferable that the lower end of the fixed guide bar 331 is formed to be inclined so as to be easily inserted into the second opening 311.

Next, the ball valve 200 controls the flow of the fluid and constitutes the other side of the hybrid valve.

The ball valve 200 is integrally formed on the other side of the conduit of the valve tube 310 and has the same configuration as the ball valve disclosed in the first embodiment, and a detailed description thereof will be omitted.
