Y-type strainer that allows visual inspection of foreign matter

Abstract

To provide a Y-type strainer that allows the sludge (garbage) storage part of the Y-type strainer to be viewed from the outside and the degree of sludge accumulation to be judged. SOLUTION: A slot (window) 6 is drilled in the surface wall of the secondary pipe 1B of the Y-type strainer so that the location of the internal debris and sludge accumulation can be seen. Also, a transparent pipe 2 that is longer than the slot 6 is placed in close contact with the wall of the slot of the secondary pipe 1B, and both ends of the pipe are sealed with O-rings 7 to prevent leakage of the internal fluid.

[0001] This invention is a method for periodically inspecting and cleaning the element screen of a Y-type strainer. There is no need to implement A Y-type strainer that allows you to check the sludge (garbage) storage area of ​​the Y-type strainer from the outside and determine the amount of sludge accumulated. Regarding . [Background technology]

[0002] Installed in the middle of horizontal liquid or gas piping to capture debris in the fluid Y-type strainer In relation to this, a strainer having an element screen and a sludge scraping mechanism, and a Y-type strainer in which the screen can be easily removed and attached, have been proposed (see Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7399525 [Patent Document 2] Patent No. 7125689 DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0004] Conventional Y-type strainers require periodic inspection and cleaning to prevent malfunctions of precision equipment such as pressure reducing valves and pressure regulating valves caused by debris and sludge in the fluid inside the piping. Even when there is not much debris or sludge accumulated, they are disassembled for inspection and cleaning, which creates the problem of wasting time. .

[0005] The present invention has been made in view of the above-mentioned problems, and aims to provide a Y-type strainer that allows the accumulation of dirt and sludge in the Y-type strainer to be checked without disassembling the strainer. . [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the Y-type strainer according to the present invention is a metal Y-type strainer provided with a filter (3) for capturing dirt and sludge flowing through a horizontally extending, linear main pipe (1A) in a secondary pipe (1B) that branches off from the main pipe (1A) and extends diagonally downward, the filter (3) being provided in the secondary pipe (1B) on the main pipe (1A) side of the Y-type strainer, and the dirt and sludge captured by the filter (3) are accumulated in the secondary pipe (1B). ) a cylindrical transparent pipe (2) is accommodated under the filter (3) of the secondary pipe (1B), and seal rings (7) for sealing the gap between the cylindrical transparent pipe (2) and the secondary pipe (1B) are provided on both sides of the length of the secondary pipe (1B), and a window (6) is provided at the position of the secondary pipe (1B) opposite to the position where the cylindrical transparent pipe (2) is accommodated and sealed by the seal ring (7) to allow observation of the state of the garbage and sludge accumulated in the secondary pipe (1B).

[0007] Furthermore, in the Y-type strainer according to the present invention, one end of the cylindrical transparent pipe (2) facing the filter (3) is open, and the other end of the cylindrical transparent pipe (2) is closed by a lid (4) that closes the secondary pipe (1B). It is characterized by:

[0008] Furthermore, the Y-type strainer according to the present invention is characterized in that the window (6) is an elongated hole-shaped window extending in the longitudinal direction of the secondary pipe (1B), and the seal ring (7) is an O-ring. [Effects of the Invention]

[0009] The Y-type strainer of the present invention can be used to check the level of debris and slush accumulation and determine the need for disassembly and cleaning of the Y-type strainer, eliminating the need for periodic disassembly and cleaning, thereby reducing maintenance costs. [Brief explanation of the drawings]

[0010] [Figure 1] External view of the Y-type strainer showing the slotted hole and a right side view. [Figure 2] Overall view and right side view showing the CD cross section of the secondary pipe. DETAILED DESCRIPTION OF THE INVENTION

[0011] An embodiment of the Y-type strainer according to the present invention will be described below.

[0012] FIG. 1 is an external view of a Y-shaped strainer according to the present invention, showing the oblong holes and a right side view, and FIG. 2 is an overall view and a right side view showing the CD cross section of the secondary pipe.

[0013] The Y-type strainer of the present invention is Sludge, etc. is discharged into the secondary pipe 1B, which branches off from the horizontally straight main pipe 1A and extends diagonally downward. To capture The filter 3 is provided, and a cylindrical pipe 2 made of a transparent material is inserted, which holds the filter 3 via a cushion 8. This Both ends of the transparent pipe 2 are provided in the sub-pipe 1B. By means of a seal ring (e.g., O-ring 7), The fluid in the secondary pipe 1B does not leak to the outside. (No leakage between the outer surface of the transparent pipe 2 and the inner surface of the sub-pipe 1B) .

[0014] Lower part of sub-pipe 1B (End opposite to the side communicating with the main pipe 1A) The cover 4 seals the secondary pipe 1B. There is a cushion 5 between the transparent pipe 2 and the cover 4, and the cover 4 is screwed into the secondary pipe 1B and sealed with an O-ring 7. 1B There are two transparent pipes The sub-pipe 1B is provided with elongated holes (elongated window) 6 having a length shorter than the interval between the grooves of the O-rings 7 provided in the sub-pipe 1B, and these elongated holes (elongated window) 6 are provided in two locations facing each other. .

[0015] To view sludge accumulated in sub-pipe 1B from the outside It is possible to make the Y-type strainer itself out of a transparent material, but it is not possible to make it out of a transparent material. as Is it glass or plastic? It is expected that Compared to metals, it is extremely weak against external forces and internal fluid pressure. Therefore, in the present invention, we focused on the fact that by combining these two, we could provide a Y-type strainer that can withstand both external forces and internal pressure, and so we made the Y-type strainer body out of metal, and housed a cylindrical transparent pipe 2 below the filter 3 in the secondary pipe 1B where the dirt and sludge accumulate.

[0016] As mentioned above, Near both ends of transparent pipe 2 teeth O-ring 7 connects with the inner surface of sub-pipe 1B Between It is sealed and this The part sealed by O-rings 7 on both ends Sub-pipe IB The elongated holes (elongated window) 6 are provided in the secondary conduit 1B, and for example, the width of the elongated holes is about 10% to 13% of the outer diameter of the secondary conduit 1B, and two elongated holes are provided at equal intervals in the outer circumferential direction of the secondary conduit 1B. The length of the elongated holes (elongated window) 6 is, for example, about 80% to 84% of the interval between the receiving grooves of the O-rings 7 provided in the secondary conduit 1B.

[0017] In addition, transparent pipe 2 The transparent pipe itself has a shape and thickness that can withstand internal pressure. 2 Metal sub-pipe 1B It is reinforced against internal fluid pressure and external forces and impact forces. [Explanation of symbols]
