Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a strainer for removing foreign matter such as dust contained in a fluid, and more particularly to a strainer suitable for use in a branch of a fluid pipe. About na. [0002] Since foreign matter such as scales and rusted pieces of iron pipes are mixed in a fluid pipe, a strainer must be provided in front of a fluid-using device or valve to supplement the fluid pipe. . FIG. 2 shows a conventional strainer and a piping system to which the strainer is applied.
This piping system is composed of a main pipe 21 and two sub pipes 22 and 2.
3 is a branch. So-called Y-type strainers 24 and 25 are disposed in the sub-pipes 22 and 23, respectively. Since the strainers 24 and 25 are the same, the strainer 24
In the following description, only the reference numeral is attached to the casing 26, and the casing 26 is provided with an inflow path 27 and an outflow path 28 coaxial with the inflow path 27.
A cylindrical screw inclined from the axis of the inflow channel 27 and the outflow channel 28
1 (shown by broken lines). Inflow channel 2
Reference numeral 7 communicates with the inside of the cylindrical screen 29, and the outflow passage 28 communicates with the outside of the cylindrical screen 29. Reference numeral 30 denotes a T joint, and reference numerals 31 and 32 denote elbows. This piping system mixes the main piping 21 with the fluid.
The foreign matter flowing from the sub-pipe 22 through the sub-pipe 22 is supplemented by the strainer 24 so that the foreign substance does not flow into a fluid-using device or the like (not shown) connected downstream. The incoming foreign matter is supplemented by a strainer 25 so that the foreign matter does not flow into a fluid-using device or the like (not shown) connected downstream. [0005] In the above, three independent articles of the strainers 24 and 25 and the T-joint 30 are required, which requires time and labor for the piping work and the space for the piping. There was a problem that became big. An object of the present invention is to provide a strainer which can reduce the number of parts and piping space by integrating a strainer and a pipe joint, focusing on the above-mentioned problems of the prior art. [0007] The features of the present invention are:
A casing, an inflow passage formed in the casing, and a plurality of outflow passages perpendicular to the inflow passage, and an inflow passage arranged in the casing in the axial direction of the inflow passage and having a plurality of inflow passages to the outside Wherein the outflow path is provided with a cylindrical screen communicating with the outflow path. According to the present invention by the above technical means, the casing is formed with an inflow path and a plurality of outflow paths perpendicular to the inflow path. And can also function as a pipe joint. In addition, since a cylindrical screen is arranged in the axial direction of the inflow passage, the inflow passage communicates with the inside and the plurality of outflow passages communicate with the outside, so that foreign matter flowing from the main pipe to the plurality of sub-pipes can be removed. Can be supplemented inside the screen. As described above, since the function of the strainer and the pipe joint can be achieved by one article, the number of parts and the piping space can be reduced by using the strainer of the present invention. The following is a description of specific embodiments of the present invention. FIG. 1 is a sectional view of a strainer according to a specific embodiment of the present invention and a configuration diagram of a piping system to which the strainer is applied. A strainer 4 is disposed at a branch between the main pipe 1 and the sub pipes 2 and 3. Strainer 4 is T-type casing 5
The inflow path 6 and the two outflow paths 7 perpendicular to the inflow path 6,
8, a cylindrical screen 9 is arranged in the axial direction of the inflow path 6, and is held by a flag 10. The inflow path 6 is connected to the main pipe 1, and the outflow paths 7 and 8 are connected to the sub pipes 2 and 3, respectively. The inflow path 6 communicates with the inside of the cylindrical screen 9, and the outflow paths 7 and 8 communicate with the outside of the cylindrical screen 9. Reference numerals 11 and 12 are elbows. The fluid in the main pipe 1 flows into the inflow path 6 of the strainer 4, passes from inside the cylindrical screen 9 to the outside, flows from the outflow path 7 to the auxiliary pipe 2, and from the outflow path 8 to the auxiliary pipe 8. Piping 3
Leaked to Foreign matter is captured when the fluid passes through the cylindrical screen 9. The strainer 4 is a conventional T-joint and 2
Acts as a strainer for the sub-piping of the book. As described above, according to the present invention, since the function of the strainer and the pipe joint can be achieved by one article, the strainer which can reduce the number of parts and the piping space can be achieved. Can be provided.
