1 to 5, a sight glass 100 for a fluid check according to an embodiment of the present invention includes a main body 110 connected to a piping 10, And a foreign matter removing unit 130 for removing foreign substances adhering to the fluid identifying unit 120. [ According to the present embodiment, the sight glass 100 for identifying the fluid injects high-pressure compressed air through the foreign material removing unit 130 to remove foreign matter adhering to the inside of the fluid check penetration unit 120. Therefore, it is possible to prevent the fluid identification opening 120 from becoming unidentifiable by the foreign substance.

The main body 110 includes a fluid inlet portion 111 and a fluid outlet portion 113 connected to the pipe 10. The body 110 is opened at both ends, and the opening 115 is sealed by the fluid identification opening 120. At this time, coupling portions 110 are formed at both ends of the main body 110 to connect the fluid identification inspecting portion 120.

The main body 110 is connected to the foreign substance removing unit 130 on the outer surface of the central part. In this embodiment, the main body 110 is shown to be formed in a cylindrical shape, but may be formed in various shapes according to the needs of the user.

The fluid check penetration part 120 is coupled to the coupling part 110a of the main body 110 so that the flow of the fluid flowing through the main body 110 can be easily confirmed.

The fluid inspecting unit 120 includes a transparent glass 121 inserted into the opening 115, a nut member 123 for preventing the glass 121 from escaping from the glass 121, (Not shown).

The sealing member 125 according to the present embodiment may be formed of any one of synthetic rubber, urethane, and silicone.

In addition, the foreign substance removing unit 130 removes foreign substances adhering to the inner surface of the glass 121 by the foreign substance removing unit 130.

The foreign substance removing unit 130 is connected to the main body 110 to remove foreign matter adhering to the glass 121 of the fluid check opening unit 120. The foreign substance removing unit 130 includes an opening and closing valve 130a connected to the main body 110 and a compressed air injecting unit for injecting the compressed air injected through the opening and closing valve 130a into the glass 121 And a compressor 130c that supplies compressed air through the on-off valve 130a.

The opening / closing valve 130a is connected to the compressor 130c through a compressed air supply line, and is opened / closed such that the compressed air is selectively supplied to the compressed air injecting unit 130b.

The compressed air injecting section 130b communicates with the opening and closing valve 130a and guides the flow of the compressed air so that the compressed air flowing through the opening and closing valve 130a is injected into the glass 121. [ The compressed air injecting portion 130b includes a valve coupling portion 131 protruding from the outer surface of the main body 110 and an air supply passage 133 provided in the main body 110 to communicate with the valve coupling portion 131. [ And an air injection member 135 for guiding the compressed air supplied through the air supply passage 133 to the glass 121.

The air supply passage 133 is provided in the main body 110 to communicate the air injection member 135 and the main body 110. The air supply passage 133 is formed by an air guide groove 133a formed on the inner surface of the main body 110 and an air guide groove 133a covering the air guide groove 133a.

The air supply passage 133 is formed between the main body 110 and the air injection member 135 and smoothly guides the compressed air flowing through the valve engagement portion 131 to the air injection member 135.

The air injection member 135 is connected to the airflow cover pipe 135a and the injection hole 135b, the connection hole 135c and the connection hole 135c so that the compressed air flowing through the air supply flow path 133 is injected into the glass 121 at a high pressure, And a pipe 135d.

The flow path cover pipe 135a is coupled to the inner surface of the main body 110 through the opening 115 to cover the air guide groove 133a and the fluid check opening 120 is supported at the upper and lower ends. An injection hole 135b communicating with the air supply passage 133 is formed at an upper end portion and a lower end portion of the flow path cover tube 135a so as to be spaced apart along the circumferential direction.

The injection hole 135b injects compressed air. This injection hole 135b is formed so as to be inclined so that the compressed air is more concentrated toward the glass 121 side. Further, the injection hole 135b is reduced in inner diameter so that the injection pressure and the velocity of the compressed air are increased.

The connection hole 135c is formed in a line so as to be positioned at both sides of the center so as to be aligned with the fluid inlet 111 and the fluid outlet 113 of the body 110. [ One of the connecting holes 135c and the fluid inlet 111 and the other connecting hole 135c and the fluid outlet 113 are connected by the connecting pipe 135d.

The connection hole 135c and the connection tube 135d smoothly transfer the fluid flowing into the main body 110 through the fluid inlet 111 to the fluid outlet 113 side.

Next, the operation of the sight glass for confirmation according to one embodiment of the present invention constructed as described above will be described.

First, when the fluid inlet 111 and the fluid outlet 113 are connected to the pipe 10, the fluid conveyed through the pipe 10 passes through the main body 110, It is possible to accurately grasp the transfer of the fluid.

If foreign substances are adhered to the glass 121 and it is difficult for the operator to precisely grasp the transfer of the fluid, the foreign substance adhered to the glass 121 can be easily and effectively removed through the operation of the foreign substance removing unit 130.

Specifically, when the opening / closing valve 130a is opened after the compressor 130c is operated, the compressed air is injected at a high pressure through the injection hole 135b via the air supply passage 133. [ The foreign matter attached to the glass 121 is removed by the pressure of the compressed air injected from the injection hole 135b.

At this time, since the injection hole 135b is inclined toward the glass 121, the inner diameter of the injection hole 135b is gradually decreased, so that the pressure and the velocity of the compressed air injected through the injection hole 135b are further increased Foreign matter of the glass 121 can be removed more effectively.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. I will understand.

Accordingly, the true scope of protection of the present invention should be defined by the claims.
