Abstract
The utility model discloses an outlet pipeline structure of a safety valve for a marine boiler, which comprises an air outlet and an outer exhaust pipe. An expansion section is arranged between the air outlet and the outer expansion pipe. The structure of the expansion section is that one end of a steam spraying pipe is fixedly connected with the air outlet, the other end of the steam spraying pipe stretches into a casing from an opening at the bottom of the casing, and the edge of the opening at the bottom of the casing is sealed and fixedly connected with the outer pipe wall of the steam spraying pipe. One end of an external connection pipe is fixedly connected with the outer exhaust pipe, the other end of the external connection pipe stretches into the casing from an opening at the top of the casing, the stretching height is higher than the expansion quantity of the safety valve, and a seal is arranged between the edge of the opening at the top of the casing and the outer pipe wall of the external connection pipe. The height of the casing is larger than the expansion quantity of the safety valve. The outlet pipeline structure of the safety valve for the marine boiler provides enough expansion surplus quantity for the safety valve, so that the safety valve cannot deform, and safety of the boiler is improved.
Description
Technical field
The utility model relates to the marine boiler safety valve, is specifically related to the outlet conduit structure of marine boiler safety valve.
Background technique
The safety valve of marine boiler is the important component part of marine boiler safety attachment, generally is positioned at the top of boiler, and its effect is when boiler pressure surpasses limit value, and ability is exhaust steam automatically, and release pressure prevents that pressure from continuing rising and working the mischief.The outlet conduit of marine boiler safety valve comprises air outlet and the outer outlet pipe that is fixedly connected with the air outlet at present, and outer outlet pipe is fixedly mounted on the hull.After boiler pressure reached limit value, the steam in the safety valve jumping up, boiler was directly drained into outside the cabin along outer outlet pipe by the air outlet of safety valve.Above-mentioned pressure release passage is simple; But since boiler from cold conditions to hot process whole can the generation expand; The displacement amount that boiler expansion produces can make safety valve and then produce displacement upwards, and all pipelines all interfix and outer outlet pipe and hull are fixed in the above-mentioned air outlet pipeline configuration, not to the surplus of top offset; Thereby cause safety valve stressed back distortion, increased unsafe factor greatly.
The model utility content
Thereby the purpose of the utility model provides a kind of outlet conduit structure that has enough expansion spaces can reduce the marine boiler safety valve of marine safety valve distortion.
For addressing the above problem; The technological scheme that the utility model adopts is: the outlet conduit structure of marine boiler safety valve; Comprise air outlet and outer outlet pipe, the air outlet and outside expansion joint is set between the outlet pipe, the structure of said expansion joint is: steam jet one end is fixedly connected with the air outlet; The other end is stretched in the housing by the housing bottom opening, and the housing bottom edge of opening seals and is fixedly connected with the steam jet outer tube wall; External connecting pipe one end is fixedly connected with outer outlet pipe, and the other end is stretched in the housing by the case top opening, stretches into the swell increment of height greater than safety valve, is provided with sealing layer between case top edge of opening and the external connecting pipe outer tube wall; The housing height is greater than the swell increment of safety valve.
Adopt the stuffing box packing sealing between described case top edge of opening and the external connecting pipe outer tube wall, stuffing box packing is the graphite packing.
Above-mentioned stuffing box packing adopts pressing plate to fix, and pressing plate one end fastening stuffing box packing makes it be close to external connecting pipe outer tube wall and case top edge of opening, and the other end is fixedly connected with housing.
The port arranged outside that described external connecting pipe stretches in the housing has baffle plate.
Described housing bottom is provided with at least one bleed outlet.
The utility model has the advantages that: the air outlet and outside expansion joint is set between the outlet pipe after; The expansion joint middle shell can move up and down along the outer tube wall of external connecting pipe; Because of the displacement that makes progress that the boiler expansion effect produces enough spaces are provided for safety valve like this; Make safety valve indeformable, improved the Security of boiler; And because of expansion joint middle shell bottom is provided with bleed outlet, the condensed water that steam brings when discharging can in time be discharged, and can not be spilled over to the boiler top and pollute, and has improved the outside clean and tidy degree of boiler.

Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify.
As shown in Figure 1; The outlet conduit structure of marine boiler safety valve; Comprise air outlet 9 and outer outlet pipe 10, air outlet 9 and outside expansion joint 12 is set between the outlet pipe 10, the structure of said expansion joint 12 is: steam jet lower end mouth 23 is connected with air outlet 9 employing flanges 1; Steam jet upper end-hole 22 is stretched in the housing 3 by housing bottom opening 31; Steam jet outer tube wall 21 and the welding of housing bottom opening 31 edges make housing 3 bottom seals and are connected firmly with steam jet 2, and the height that steam jet 2 stretches in the housing 3 can be confirmed according to actual needs; External connecting pipe upper end-hole 53 and outer outlet pipe 10 firm welding; External connecting pipe lower end mouth 52 is stretched in the housing 3 by case top opening 32; The outside of external connecting pipe lower end mouth 52 is welded with baffle plate 4; Baffle plate 4 makes external connecting pipe 5 when work, can not break away from housing 3, and the height that external connecting pipe 5 stretches in the housing 3 can be confirmed according to safety valve 11 actual swell incremenies; Adopt 7 sealings of graphite packing between external connecting pipe outer tube wall 51 and the case top opening 32; Anchor stone disc root 7 be pressing plate 6; Pressing plate 6 one end fastening graphite packings 7 make it be close to the edge of external connecting pipe outer tube wall 51 and case top opening 32, and the other end is connected with bolt with housing 3 tops, pressing plate various informative; As long as its purpose is fixed the graphite packing; In housing 3 bottoms a bleed outlet 8 is set, is used for discharged steam to meet the condensed water of cold formation, the quantity of bleed outlet can be provided with according to actual needs.
When boiler 13 passed through safety valve 11 pressure releases, steam was drained into outside the ship storehouse by outer outlet pipe 10 in steam jet 2 spirt external connecting pipes 5 from air outlet 9 then.In this process; Safety valve 11 can produce displacement upwards along with the expansion of boiler 13; This displacement amount can pass to housing 3 through steam jet 2; Safety valve 11, steam jet 2 and housing 3 are upwards slided along the outer tube wall that amount makes housing 3 be close to external connecting pipe 5 together, like this safety valve 12 with regard to can not be because there not being enough expansion spaces stress deformation; The condensed water that steam is met cold formation in the work so can not make a large amount of condensed waters have little time discharging yet and overflow and pollute the boiler top along bleed outlet 8 discharges.
