Embodiment
In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, now control illustrates
Specific embodiment of the present utility model.
The utility model is directed to the actual demand of domestic super-critical and ultra super-critical power unit boiler heating surface pickling interface, leads to
Non-return valve, the big overflow manually operated door crossed in boiler heating surface pickling interface solve pickling using the scheme for installing interim bonnet additional and set
Standby otch and the complicated procedures of forming problem of welding.
A kind of supercritical boiler heating surface pickling interface arrangement of no-welding of the present utility model, it is preferably implemented
In example, refer to shown in Fig. 1 and Fig. 2, the supercritical boiler heating surface pickling interface arrangement of the no-welding fills including entrance
Put and outlet device, the inlet device include temporary inlet bonnet 1, the temporary inlet bonnet 1 is installed on boiler water circulating pump
The bonnet installation place of outlet non-return valve 2, offers the first intermediate throughholes on the temporary inlet bonnet 1, logical among described first
Temporary inlet pipe 7 is connected with the outside of hole；The outlet device includes temporary export bonnet 8, and the temporary export bonnet 8 is installed on
The bonnet installation place of storage tank overflow sluice valve, offers the second intermediate throughholes on the temporary export bonnet 8, in described second
