For example, the flow path communication between the first inner hole 110a in the first body 110 and the second inner hole 210a in the second body 210 is performed in the combined state of the first and second units 100 and 200. The first valve body 130 is advanced and pushes the second valve body 230 backward. The flow path blocking of the second inner hole 210a is retracted by the first valve body 130 in the coupled state of the first and second units 100 and 200, and the second valve body 230 is elastically supported and returned to the front. Or the second body 210 is dropped from the first body 110 and in contact with the front end surface of the first valve body 130 during emergency separation of the first and second units 100 and 200. 2 is made when the valve body 230 is elastically supported and returns to the front.

For example, the second body 210 may have a valve seat 211 formed with an inner diameter smaller toward the front side on the inner circumferential surface of the front side second inner hole 210a. For example, the valve seating portion 211 may seat the second valve body 230 which is advanced forward, for example, the second sealing portion 233 of the second valve body 230, and may maintain airtightness. For example, the valve seat 211 may have a plurality of inclined surfaces or curved structures formed in one step or one step. For example, at this time, the minimum inner diameter of the valve seat 211 may be larger than the maximum diameter of the front portion of the first valve body 130. Accordingly, when the first and second units 100 and 200 are coupled, the front portion of the first valve body 130 pushes the second valve body 230 backward and the first and second inner holes 110a and 210a. The passage of the liver can be opened.

For example, the second guide 220 may be fastened to the second inner hole 210a at the rear side of the second inner hole 210a of the second body 210. For example, it may be fastened by screwing or fastened in a manner in which the second guide 220 is seated on a step formed at the rear side of the second inner hole 210a.

For example, the second body 210 may be formed with a front circumferential protrusion 213 protruding outward from the periphery of the front end. The front surface of the front circumferential protrusion 213 of the second body 210 may form a front cross section of the second body 210. For example, in one example, the fixed hook portion 271 of the fixed brake portion 270 to be described later on the circumference of the front circumferential projection 213 is hinged, or in another example hinged around the flange portion 250 The other end side fixing jaw 271a of the fixed hook portion 271 may be supported on the rear surface of the front circumferential protrusion 213. That is, as shown in Figs. 1 to 4c, the hinge engaging side of the fixed hook portion 271 is coupled on the circumference of the front circumferential protrusion 213 or the fixed hook portion 271 as shown in Figs. 5A to 6B. The fixing jaw 271a is supported on the rear surface of the front circumferential protrusion 213 and fixes the coupled state of the second body 210 and the flange part 250. For example, when the fixing jaw 271a of the fixing hanger 271 is supported on the rear surface of the front circumferential protrusion 213, as shown in FIGS. 5A to 6B, emergency separation of the first and second units 100 and 200 is performed. When the release release portion 273 of the fixed brake portion 270, for example, the release pin 273b presses the circumference of the front circumference protrusion 213, and the front circumference protrusion by the fixing jaw 271a of the fixed hook portion 271 ( 213 may be released. For example, in FIGS. 5A to 6B, the fixing jaw 271a of the fixed brake part 270 is supported on the rear surface of the front circumferential protrusion 213 of the second body 210 and releases the fixing part 273, for example, a release pin. When 273b presses the circumference of the front circumferential protrusion 213, an additional protrusion 213b is formed on the circumference of the front circumferential protrusion 213, and the rear surface of the additional protrusion 213b is fixed to the chin ( 271a) may support and release the outermost side 273, for example release pin 273b.

For example, the basic circumferential diameter of the front circumferential protrusion 213 of the second body 210 is formed to be smaller than the circumferential diameter of the circumferential protrusion 113 of the first body 110 to the basic circumferential diameter of the flange portion 250. , Fastening and release by the fastening hook 155 of the fastening fixing part 150 can be made easily. In addition, referring to FIGS. 1 to 4c, when the fixing hook part 271 of the fixed brake part 270 is hinged to the front circumferential protrusion 213 of the second body 210, the front of the second body 210 is hinged. The hinge frame 213a may protrude from the basic circumference of the circumferential protrusion 213 and may be hinged to the hinge axis 271c of the hinge frame 213a. Accordingly, in another example, referring to FIGS. 5A to 6B, the fixing hook part 271 of the fixed brake part 270 is hinged to the hinge frame 250c protruding from the basic circumference of the flange part 250 to fix the hook. The fixed jaw 271a of the part 271 supports the rear surface of the front circumferential protrusion 213 of the second body 210 after the protrusion 213b additionally protruded from the basic circumference of the front circumferential protrusion 213. It can be supported.

In one example, the second body 210 may have a plurality of fastening protrusions 212 protruding on the front end surface. The fastening protrusion 212 of the second body 210 is fastened to a plurality of grooves 250b formed on the rear surface of the flange portion 250 coupled to the front end of the second body 210.

For example, a flange tube connector 290 may be flange coupled to the rear of the second body 210, and at this time, the sealing member 291 for maintaining the airtightness with the rear end surface of the second body 210 is flange coupled. It can be installed between the faces.

Second valve body portion 230

Referring to FIGS. 1, 2, 3a, 3b, 4a, 4b, 5b, 6a and / or 6b, referring to FIG. 2, the second valve body portion 230 is formed in the second inner hole 210a of the second body 210. Is elastically supported. The second valve body 230 is in close contact with the second inner hole 210a when the second body 210 is separated, and blocks the second inner hole 210a. In addition, when the first and second units 100 and 200 are coupled, the second valve body 230 is pushed backward as the first valve body 130 contacts, and the flow path of the second inner hole 210a is opened. Let's do it. For example, the second valve body 230 returns to the front by an elastic force as the first valve body 130 is retracted in the coupled state of the first and second units 100 and 200, and the second inner hole 210a. You can block the flow path. In addition, the second valve body 230 may block the flow path of the second inner hole 210a by an elastic force according to the emergency separation of the first and second units 100 and 200.

1, 2, 3a, 3b, 4a, 4b, 5b, 6a and / or 6b, in one example, the second valve body portion 230 includes a second shaft portion 231, a second valve portion ( 232, a second sealing part 233, and a second spring 234. The second shaft part 231 is inserted into the second guide hole 221 of the second guide 220 and slides. The second valve portion 232 is formed in front of the second shaft portion 231 to form the front portion of the second valve body portion 230. In the combined state of the first and second units 100 and 200, the second valve part 232 contacts the first valve part 132 of the first valve body part 130. The diameter of the second valve portion 232 is larger than the minimum inner diameter of the valve seat 211 in the direction of the inner peripheral surface of the second inner hole (210a). Accordingly, the second valve body 230 may retreat and return forward in the second inner hole 210a and the flow path of the second inner hole 210a may be opened and closed. For example, the second valve portion 232 has an installation surface on which the second sealing portion 233 is installed so as to be parallel to or opposite to a structure such as an inclination or a curved surface of the valve seat 211. A ring groove in which the second sealing part 233 is installed may be formed. The second sealing part 233 is installed around the second valve part 232 and maintains the airtightness between the valve seat 211 and the second valve part 232 when the second body 210 is separated. For example, the second sealing part 233 is installed in a ring groove formed around the second valve part 232 parallel to or facing the structure of the inclined to curved surface of the valve seating part 211 and the valve seating part 211. Airtightness is maintained between the second valve portion 232 and the second internal hole 210a to block the flow path. For example, the second sealing part 233 may be a rubber or resin sealing ring.

Next, one end of the second spring 234 of the second valve body 230 is supported by the second guide 220 to the second inner hole 210a and the second inner hole when the second body 210 is separated. The elastic force for blocking the flow path of 210a is provided. For example, the second spring 234 is installed around the circumference of the second shaft portion 231, and the other side of the second spring 234 is the front protruding step of the second shaft portion 231 or the second valve portion ( The rear face side of 232 can be elastically supported. The second spring 234 provides elastic force to the second valve body 230 so that the flow path of the second inner hole 210a is blocked by the second valve 232 when the second body 210 is separated. When the connection flow path is opened, the second valve part 232 is pushed by the first valve part 132 and the second spring 234 contracts. When the connection flow path is blocked, the second spring 234 provides elastic force and the second valve is closed. The part 232 blocks the second inner hole 210a.

For example, the size of each of the front end face of the first valve part 132 and the front end face of the second valve part 232 may be matched with each other. For example, when the flow path of the second inner hole 210a is blocked, the front cross section of the second valve part 232 exposed from the front side is flat and, for example, the same as or substantially matched with the front surface of the first valve part 132. It may have a size. Accordingly, when the first and second units 100 and 200 are normally separated, the front surface of the second valve unit 232 and the front surface of the first valve unit 132 may contact each other until the connection flow path is blocked. Leakage can be minimized or minimized.
