And the insertion portion 320 fixed by being inserted into the protrusion 311 of the extension portion 310 may be included.

As shown in FIGS. 1 and 4 , an extension 310 extending downward is formed in the bracket 100, and the extension 310 may be formed in the form of a protrusion 311 by expanding its cross-sectional area at the end side. there is.

The protrusion 311 is inserted into the insertion part 320 for interference fit, and after being inserted, the protrusion 311 protruding in a direction crossing the longitudinal direction from the extension part 310 is caught, so that the bracket 100 And the valve module 200 can be fastened.

Through this, the operator can easily combine the valve module 200 and the bracket 100 inside the tank T in a state where the field of view is not secured.

A cross-sectional area of the protrusion 311 may gradually decrease in a direction in which the protrusion 311 is inserted into the insertion portion 320 .

As the protrusion 311 is formed such that its cross-sectional area gradually decreases in the direction in which it is inserted into the insertion portion 320, the protrusion 311 may be formed in a shape such as a locking jaw on a thicker side.

Through this, when the protrusion 311 is inserted into the insertion part 320, it can be easily inserted, and in the direction opposite to the insertion direction, one side of the valve module 200 is caught on a portion having a large cross-sectional area of the protrusion 311, and coupling is performed. It can be fixed without being released.

A plurality of protrusions 311 may be spaced apart from each other in a direction in which they are inserted into the insertion part 320 .

2 and 3, a plurality of protrusions 311 may be formed in a vertical direction, and when a plurality of protrusions 311 penetrate the insertion part 320, the uppermost or middle protrusion 311 is hooked and fixed. It can be.

Through this, even if a part of the external protrusion 311 is damaged, it is caught on the protrusion 311 located below, thereby preventing disconnection between the bracket 100 and the valve module 200.

The bracket 100 may include a guide portion that extends downward from the outside of the extension portion 310 to guide engagement between the extension portion 310 and the insertion portion 320 .

As shown in FIGS. 1 to 3, the bracket 100 extends downward from the outside of the extension part 310, and when the extension part 310 is inserted into the insertion part 320, it is located on the outside of the insertion part 320. A guide portion may be formed.

Through this, there is an effect that the operator can accurately couple by being guided by the guide unit in a state where the field of view is not secured, and the effect of protecting the valve module 200 and the insertion unit 320 by the guide unit there is.

The fastening portion 300 includes a protrusion 330 protruding and extending from the valve module 200 in a direction crossing the vertical direction of the tank T, and a high protrusion extending downward from the bracket 100 to surround the protrusion 330. Government 340 may be included.

As shown in FIG. 7, the fastening part 300 includes a protrusion 330 extending from the valve module 200 in a direction crossing the vertical direction of the tank T and a protrusion 330 extending downward from the bracket 100. ) A fixing part 340 formed to surround the may be formed.

Through this, the operator can move the valve module 200 from the bottom to the top and insert the protruding part 330 into the fixing part 340 to couple the valve module 200 to the tank T from the inside of the tank T. there is.

The fixing part 340 may include a support protrusion 341 whose end protrudes toward the center of the protruding part 330 and fixes the protruding part 330 when fastened with the protruding part 330 .

Support protrusion 341 protruding in a direction crossing the direction in which the end of the fixing part 340 extends in order to prevent the valve module 200 from being disengaged downward when the protruding part 330 is inserted into the fixing part 340 Is formed, the protruding portion 330 is inserted between the support protrusions 341 through an interference fit, and the protruding portion 330 may be fixed inside the fixing portion 340.

A temporary coupling part 400 formed on the bracket 100 or the valve module 200 to temporarily couple the valve module 200 before the fastening part 300 is fastened; may be further included.

The temporary coupling part 400 is formed on the bracket 100 or the valve module 200 to assist the fastening force of the fastening part 300, so that the valve module 200 is attached to the bracket 100 before the fastening part 300 is fastened. It is formed to be rigid, and then the fastening part 300 is fastened to prevent the valve module 200 from being disconnected from the bracket 100.

The temporary coupling portion 400 includes a hook 410 extending downward from the bracket 100 and bent in the opposite direction to the direction in which the end is extended, and a hook protruding from the valve module 200 to be caught on the hook 410 ( 420) may be included.
