Background technique

Sealed valve is component part important in safety engineering, be mainly used for the cutting of pipeline medium, throttling, pressure regulation and Change flow direction etc., the superiority and inferiority of sealed valve quality directly affects the normal of these devices, safe handling and safeguard function, and plays Vital effect, it is currently, national, city's key project to put into operation, need a large amount of valve products matched；It is close The tightness of valve closing door is the important symbol of product quality, however the sealing knot that existing link-type sealed valve generallys use Structure are as follows: coat sealing ring in the outer diameter of valve plate, when valve plate is closed, make to guarantee between valve plate and valve body by sealing ring good Leakproofness, but the frequent opening and closing of sealed valve will cause abrasion occurs between valve plate and valve body and between causing therebetween Gap increases, and when abrasion reaches a certain level, pipeline medium can be leaked from gap location.Flange opens and closes lid door in the prior art Inconvenience, while airtightness is bad, is easy to happen gas leakage, influence using safety, have gas leakage, influence technical interior The loss of air quantity, wind pressure in personnel safety and ventilating system.

Utility model content

The purpose of this utility model is to provide a kind of hermatic door that can be manually rotated unlatching, mainly solve to deposit in the prior art Flange opening and closing lid door it is inconvenient, while the problem of poor sealing.

To achieve the goals above, the technical solution adopted in the utility model is as follows:

A kind of hermatic door can be manually rotated unlatching, including the sealed chamber vertically installed, outer ring is fixed on seal chamber ceiling The bearing in portion center, is nested with the flange on bearing inner race, and the cursor being fixedly connected with flange base is provided with sealed chamber The indoor opening of seal chamber is gone up and be used to pass in and out, the arc gear door in sealed chamber and for occlusion of openings is mounted on, one end is solid It is scheduled on arc gear door, the convex block that the other end and cursor are connected and driven by cursor, is mounted in sealed chamber and is in Annular and the mounting groove that door is kept off for limiting arc, are mounted on the first sealing ring of a circle in mounting groove, and are mounted on opening The second sealing ring where the sealed chamber on side one week.

Further in the cursor includes the first linking arm that one end is fixedly connected with flange and both ends difference The second linking arm being flexibly connected with the first linking arm and convex block.

Preferably, second linking arm is in I-shaped, second linking arm and the first linking arm and convex block and second Linking arm junction opens up fluted, wherein the first linking arm and convex block are inserted into groove by roller bearing fixed thereto and are realized With being flexibly connected for the second linking arm.

Specifically, the bottom of first sealing ring is equipped with that several to prevent the first sealing ring from sliding in mounting groove convex Point.

Compared with prior art, the utility model has the following beneficial effects:

(1) the utility model is rotated by flange drives cursor rotation, the mutual gear connecting by convex block with cursor Plate rotation to open or stop opening, and is located on the inside of sealed chamber in opening and is equipped with one week the second sealing ring, and set The mounting groove set can keep off door to arc and limit, so that arc gear door is bonded more closely with the second sealing ring, To realize better seal, and according to the utility model this setup, can be very good to open arc gear door, it will not In the presence of being not easy the case where opening in the prior art.

(2) the utility model is equipped with several salient points in the bottom of the first sealing ring, can keep off Men An in this way to avoid arc The situation for driving the first sealing ring mobile during sliding in tankage occurs, so that entire sliding process is more smooth.

(3) the utility model is due to being provided with the first sealing ring 9 in mounting groove 8, so having in the course of rotation very Big resistance, using the first linking arm 11 by roller bearing with the second linking arm 12 is this be flexibly connected by the way of, can alleviate pair The damage of cursor 4.
