Abstract
The invention relates to the technical field of sealing, in particular to a movable sealing device for a quick door opening type pressure container. The movable sealing device comprises outer sealing rings and inner sealing rings, wherein the outer sealing rings are arranged on a kettle cover of the pressure container; one end face of each outer sealing ring is a plane perpendicular to the surface of the outer sealing ring, and an annular groove is formed in the other end face of each outer sealing ring; the section of the annular groove is a cone with a relatively wide opening and a relatively narrow bottom; a bulge is formed on one end face of each inner sealing ring, and the other end face of each inner sealing ring is concave; and the bulge of each inner sealing ring is embedded into the annular groove of each outer sealing ring. By the movable sealing device, the inner sealing rings are pushed by thrust produced by steam, liquid, air and the like to be pressed against the outer sealing rings, and the outer sealing rings and the kettle cover are firmly sealed, so that abrasion of the sealing rings can be reduced, and the service life of the movable sealing device can be prolonged.
Description
Technical field
The present invention 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 especially easily to damage, and 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.
Summary of the invention
The technical problem to be solved in the present invention 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 technical solution adopted for the present invention to solve the technical problems 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, described inner seal ring wherein an end face has projection, the other end concaves, 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 invention has the beneficial effects as follows, fast opening type pressure container movable sealer of the present invention 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, and can reduce ring wear like this, increase its working life.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of fast opening type pressure container movable sealer of the present invention.
Among the figure: 1. exterior seal ring, 11. annular grooves, 2. inner seal ring, 21. projections.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
The structural representation of the specific embodiment of fast opening type pressure container movable sealer of the present invention 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 present invention 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 invention as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this invention technological thought, carry out various change and modification fully.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
