Abstract
The utility model relates to the technical field of sealing, in particular to a quick-door-opening type pressure container movable sealing device. The quick-door-opening type pressure container movable sealing device comprises an outer sealing ring and an inner sealing ring. The outer sealing ring is installed on a kettle cover of a pressure container. One end face of the outer sealing ring is a plane perpendicular to the ring face of the outer sealing ring. An annular groove is formed in the other end face of the outer sealing ring. A cross section of the annular groove is in a cone shape with the mouth portion wide and the bottom narrow. One end face of the inner sealing ring is provided with a protrusion and the other end face of the inner sealing ring is inwards concave. The protrusion of the inner sealing ring is installed in the annular groove of the outer sealing ring in an embedded mode. According to the quick-door-opening type pressure container movable sealing device, the inner sealing ring is pushed to be abutted against the outer sealing ring with steam, liquid, air and the like as driving force, and then the outer sealing ring and the kettle cover are firmly sealed so that abrasion of the sealing rings is reduced and service life of the sealing rings is prolonged.
Description
Technical field
The utility model relates to technical field of sealing technology, especially a kind of fast opening type pressure container movable sealer.
Background technique
Seal ring is a kind of accessory that is widely used in the industries such as pressurized container, normal pressure container, Valve joint, it is according to seal request, and Environmental Conditions is classified, and seal ring is of a great variety on the market at present, but all be static sealing without exception, reach the effect of sealing by extruding.When being applied to the door-opening pressure vessels such as autoclave, reactor, can reach sealing effect by rotary squeezing, but the disadvantage that exists is exactly to damage especially easily, needs huge stocks to change, and changes in average 3 days, if container is excessive, such as 2.85 meters of φ, the large still that φ is 3.2 meters, frequent has increased user cost greatly like this, as long as one has wearing and tearing to change, solve this problem so be necessary to design a kind of seal arrangement that increases working life.
The model utility content
The technical problems to be solved in the utility model is: easy to wear in order to solve in the prior art seal ring, change frequently technical problem, and a kind of fast opening type pressure container movable sealer is provided, improve working life, reduce operating cost.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of fast opening type pressure container movable sealer, comprise exterior seal ring and inner seal ring, described exterior seal ring is installed on the kettle cover of pressurized container, a wherein end face of described exterior seal ring is the plane perpendicular to exterior seal ring circle face, have annular groove on the other end, the cross section of described annular groove is the narrower taper of oral area wider bottom, a wherein end face of described inner seal ring has projection, the other end concaves, and the projection of described inner seal ring is flush-mounted in the annular groove of exterior seal ring.
Further, the convex cross section of described inner seal ring also is taper, and described protruding opening angle is greater than the opening angle of annular groove.
The beneficial effects of the utility model are, fast opening type pressure container movable sealer of the present utility model utilizes steam, liquid, air etc. to promote the upper exterior seal ring in inner seal ring top for Driving force, then exterior seal ring and kettle cover firmly seal, can reduce ring wear like this, increase its working life.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of fast opening type pressure container movable sealer of the present utility model.
Among the figure: 1. exterior seal ring, 11. annular grooves, 2. inner seal ring, 21. projections.
Embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic representation of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
The structural representation of the specific embodiment of fast opening type pressure container movable sealer of the present utility model as shown in Figure 1, comprise exterior seal ring 1 and inner seal ring 2, exterior seal ring 1 is installed on the kettle cover of pressurized container, a wherein end face of exterior seal ring 1 is the plane perpendicular to exterior seal ring 1 circle face, have annular groove 11 on the other end, the cross section of annular groove 11 is the narrower taper of oral area wider bottom, a wherein end face of inner seal ring 2 has projection 21, the other end concaves, the projection 21 of inner seal ring 2 is flush-mounted in the annular groove 11 of exterior seal ring 1, in order to guarantee to seal gapless, so that inner seal ring 2 can fit tightly in the annular groove 11 of exterior seal ring 1, projection 21 cross sections of inner seal ring 2 also are taper, and protruding 21 opening angles are greater than the opening angle of annular groove 11.
The utility model is take steam, liquid, air etc. as Driving force, promote the upper exterior seal ring 1 in inner seal ring 2 tops, then exterior seal ring 1 seals with kettle cover, after pressurized container work is finished, make inner seal ring 2 hold exterior seal ring 1 toward pulling back to make the sealing device to retract by exhaust, so just can the rotating kettle door and can not damage seal ring.
Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this model utility technological thought, carry out various change and modification fully.The technical scope of this model utility is not limited to the content on the specification, must determine its technical scope according to the claim scope.
