Abstract
A kind of spallation neutron source target container is connected seal arrangement with target car, and described connection seal arrangement comprises W type elastic ring, and the outer ring at the two ends of described elastic ring has groove, places Expanded graphite ring in described groove.The invention provides a kind of lift-off seal performance, the spallation neutron source target container that eliminates safe hidden trouble is connected seal arrangement with target car.
Description
Technical field
The present invention relates to a kind of spallation neutron source target container and target car connection set.
Background technique
At present, external spallation neutron source target container is connected seal arrangement and adopts metal bellows both sides to add metal air film form with target car.Its structure is: to be sealed of target car place's installation one wavy metal tube sealing device, be double-ply bellows structure in the middle of this device, two abutted flanges are welded at bellows two ends respectively, two flanged surfaces weld again two metallic thin films.Before the work of target station, target car is moved to target container front end, seal arrangement one end is made to be close to target seal of vessel face, now inflate in metal bellows, because metal bellows and metallic thin film are interconnected, therefore under the effect of pressurized gas, metal bellows struts to two ends, metallic thin film expands, thus makes the tight pressing of film and target seal of vessel face, to reach sealing effect.Because the elongation of metallic thin film and bellows is limited, so this kind of sealing means sealing compensation scope is little, required target seal of vessel face requirement on machining accuracy is high, and must ensure that pressurized gas is in normally open when sealing, air pressure is difficult to control, once gas leakage, then seals malfunctioning immediately.So there is potential safety hazard to a certain extent in seal arrangement.
Summary of the invention
In order to overcome the poor sealing performance of existing spallation neutron source target container and target car connection set, there is the deficiency of potential safety hazard, the invention provides a kind of lift-off seal performance, the spallation neutron source target container that eliminates safe hidden trouble is connected seal arrangement with target car.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of spallation neutron source target container is connected seal arrangement with target car, and described connection seal arrangement comprises W type elastic ring, and the outer ring at the two ends of described elastic ring has groove, places Expanded graphite ring in described groove.
Further, the outer ring at the two ends of described elastic ring has two grooves, and described two grooves are arranged with one heart, and the groove at two ends is symmetrical arranged.
Beneficial effect of the present invention is mainly manifested in: lift-off seal performance, eliminate safe hidden trouble.
Accompanying drawing explanation
Fig. 1 is that spallation neutron source target container is connected the schematic diagram of seal arrangement with target car.
Fig. 2 is that spallation neutron source target container is connected the scheme of installation of seal arrangement with target car.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
See figures.1.and.2, a kind of spallation neutron source target container is connected seal arrangement with target car, and described connection seal arrangement comprises W type elastic ring 3, and the outer ring at the two ends of described elastic ring 3 has groove, places Expanded graphite ring in described groove.
The outer ring at the two ends of described elastic ring 3 has two grooves, and described two grooves are arranged with one heart, and the groove at two ends is symmetrical arranged.Certainly, three even more grooves can also be had.
In the present embodiment, flexible graphite sealing outer shroud 1 and flexible graphite sealing inner ring 2 are arranged in W type elastic ring 3 groove, again W type elastic ring 3 is fixed on target car 5, promoting target car makes flexible graphite sealing outer shroud 1 contact with target seal of vessel face with flexible graphite sealing inner ring 2, apply a thrust now to target car 5, W type elastic ring 3 is compressed, fixed target car 5) now play seal action by the outside elastic force of W type elastic ring 3.
Change original air-tight structure, directly utilize metal rigidity resilience to seal.The sealing configuration of the design is, a W type elastic ring, spring-like structure, and two grooves are opened at elastic ring two ends respectively, places seal element in groove, and this seal element adopts Expanded graphite ring, is first placed in groove by Expanded graphite ring during sealing.Again this whole set of seal arrangement is arranged on target car sealing surface place.Then promote target car near target container, make the other end of seal arrangement be close to target seal of vessel face, apply a thrust then to target car, W type elastic ring is deformed, now lock target car position, the resilience by W type elastic ring seals.This seal arrangement realizes by mechanical resilience completely, and more former seal arrangement is compared, and without pressurized gas equipment, and reduce pipeline connection, in machining, precision reduces and maintenance aspect.
Claims (2)
1. spallation neutron source target container is connected a seal arrangement with target car, it is characterized in that: described connection seal arrangement comprises W type elastic ring, and the outer ring at the two ends of described elastic ring has groove, places Expanded graphite ring in described groove.
2. spallation neutron source target container as claimed in claim 1 is connected seal arrangement with target car, and it is characterized in that: the outer ring at the two ends of described elastic ring has two grooves, described two grooves are arranged with one heart, and the groove at two ends is symmetrical arranged.
