Abstract
Herein is a coupler and a clean connection device having the same, which can automate a series of operations for connecting and disconnecting a male coupler to and from a female coupler, clean and dry a wetted portion, drain residual liquid of chemicals together with cleaning water without external leakage in safety when the coupler is separated, and clean and dry the wetted surface before connection and after separation, thereby enabling a clean connection.
Claims12
A coupler mounted in a clean connection device including a clean female coupler and a male coupler to load and unload chemicals from one tank to another tank,
- wherein the male coupler comprises a male check plunger for opening and closing a flow path while sliding in a male coupler body, and the clean female coupler comprises a female check plunger for opening and closing a flow path while sliding in a clean female coupler body,
- wherein a coupler cleaning module is disposed to clean and dry wetted surfaces of the male coupler and the clean female coupler, and
- wherein the clean female coupler body has a first O-ring disposed on the clean female coupler body to prevent residual liquid of the chemicals, which is generated while the male coupler and the clean female coupler are separated from each other in a state in which the male coupler is inserted into the clean female coupler, from leaking to the outside.
The coupler according to claim 1, wherein the coupler cleaning module injects cleaning fluid or drying fluid into an inner space of the female coupler body in a state in which the male coupler is inserted into the clean female coupler body and before the male check plunger and the female check plunger come into contact with each other. 0 3. The coupler according to claim 2, wherein the clean female coupler body is formed in a cylindrical shape and comprises an injection port and a discharge port formed in the outer circumferential surface thereof, the injection port is formed to supply the cleaning fluid or the drying fluid to the inner space of the clean female coupler body, and the discharge port is formed to drain the cleaning fluid or the drying fluid from the inner space of the clean female coupler body, and
- further comprising a contaminant draining means for cleaning and drying the wetted surfaces of the male coupler and the clean female coupler by draining the fluid introduced through the injection port to the discharge port.
The coupler according to claim 3, wherein the injection port and the discharge port are formed to be spaced apart from each other in the insertion direction of the male coupler and the clean female coupler.
A clean connection device including a clean female coupler and a male coupler to load and unload chemicals from one tank to another tank,
- wherein the male coupler comprises a male check plunger for opening and closing a flow path while sliding in a male coupler body, and the clean female coupler comprises a female check plunger for opening and closing a flow path while sliding in a clean female coupler body,
- wherein a coupler cleaning module is disposed to clean and dry wetted surfaces of the male coupler and the clean female coupler, and
- wherein the clean female coupler body has a first O-ring disposed on the clean female coupler body to prevent residual liquid of the chemicals, which is generated while the male coupler and the clean female coupler are separated from each other in a state in which the male coupler is inserted into the clean female coupler, from leaking to the outside.
