Abstract
The invention discloses a connection sealing device for a spallation neutron source target container and a target vehicle. The connection sealing device comprises a W-shaped elastic ring, a slot is respectively formed on an outer periphery on each of two ends of the elastic ring, and a flexible graphite ring is arranged in the slot. By the adoption of the connection sealing device for the spallation neutron source target container and the target vehicle, the sealing performance is promoted, and hidden safety risks are eliminated.
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 employing metal bellows both sides and adds metal air film form with the target car.Its structure is: to be sealed of target car locates to install a wavy metal tube sealing device, is the double-ply bellows structure in the middle of this device, and two abutted flanges are welded at the bellows two ends respectively, weld two metallic thin films on two flanged surfaces again.Before the work of target station, the target car is moved to target container front end, make seal arrangement one end be close to target seal of vessel face; Inflate this moment in metal bellows, because metal bellows and metallic thin film be interconnected, so under the effect of pressurized gas; Metal bellows struts to two ends; Metallic thin film expands, thereby makes film and the tight pressing of target seal of vessel face, to reach sealing effect.Because the elongation of metallic thin film and bellows is limited, so this kind sealing means sealing compensation scope is little, desired target seal of vessel face requirement on machining accuracy is high; And when sealing, must guarantee that pressurized gas is in normally open; Air pressure is difficult to control, in case gas leakage, then sealing is malfunctioning immediately.So there is potential safety hazard to a certain extent in seal arrangement.
Summary of the invention
For the poor sealing performance that overcomes existing spallation neutron source target container and target car connection set, the deficiency that has potential safety hazard, the spallation neutron source target container that the present invention provides a kind of lift-off seal performance, eliminate safe hidden trouble is connected seal arrangement with the 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 the target car, and said connection seal arrangement comprises W type elastic ring, and the outer ring at the two ends of said elastic ring has groove, places the Expanded graphite ring in the said groove.
Further, the outer ring at the two ends of said elastic ring has two grooves, and said two grooves are provided with one heart, and the groove at two ends is symmetrical set.
Beneficial effect of the present invention mainly shows: the lift-off seal performance, eliminate safe hidden trouble.
Description of drawings
Fig. 1 is spallation neutron source target container is connected seal arrangement with the target car a schematic diagram.
Fig. 2 is spallation neutron source target container is connected seal arrangement with the target car a scheme of installation.
Embodiment
Below in conjunction with accompanying drawing the present invention is further described.
See figures.1.and.2, a kind of spallation neutron source target container is connected seal arrangement with the target car, and said connection seal arrangement comprises W type elastic ring 3, and the outer ring at the two ends of said elastic ring 3 has groove, places the Expanded graphite ring in the said groove.
The outer ring at the two ends of said elastic ring 3 has two grooves, and said two grooves are provided with one heart, and the groove at two ends is symmetrical set.Certainly, also can have three even more groove.
In the present embodiment; Expanded graphite sealing outer shroud 1 is installed in W type elastic ring 3 grooves with the interior ring 2 of Expanded graphite sealing; Again W type elastic ring 3 is fixed on the target car 5, promotes the target car and make in Expanded graphite sealing outer shroud 1 and the Expanded graphite sealing ring 2 contact, apply a thrust to target car 5 at this moment with target seal of vessel face; Make W type elastic ring 3 compress fixed target car 5) lean on this moment W type elastic ring 3 outside elastic force to play seal action.
Change original hermetic seal structure, directly utilize the metal rigidity resilience to seal.The design's sealing configuration does, a W type elastic ring, and the spring-like structure, two grooves are opened at the elastic ring two ends respectively, place seal element in the groove, and this seal element adopts Expanded graphite ring, at first the Expanded graphite ring is placed in the groove during sealing.Again this a whole set of seal arrangement is installed in target car sealing surface place.Promote the target car then near the target container, make the other end of seal arrangement be close to target seal of vessel face, apply a thrust for then the target car, make W type elastic ring deform, lock target car position this moment, lean on the resilience of W type elastic ring to seal.This seal arrangement leans on mechanical resilience to realize that more former seal arrangement is compared fully, without pressurized gas equipment, and reduces pipeline and connects, and aspect machining, precision reduces and safeguards the aspect.
Claims (2)
1. a spallation neutron source target container is connected seal arrangement with the target car, and it is characterized in that: said connection seal arrangement comprises W type elastic ring, and the outer ring at the two ends of said elastic ring has groove, places the Expanded graphite ring in the said groove.
2. spallation neutron source target container as claimed in claim 1 is connected seal arrangement with the target car, and it is characterized in that: the outer ring at the two ends of said elastic ring has two grooves, and said two grooves are provided with one heart, and the groove at two ends is symmetrical set.
