Abstract

The utility model relates to a rapid disconnection flange with a screw engagement, comprising a flange 4 connected with a sealing head 3 and a flange 7 connected with a barrel body 2, a flange 7'connected with a sealing head 1, a flange 8 connected with the barrel body 2, an outer hoop 9. The peripheries of the convex parts of concave and convex surfaces which are symmetrically arranged on the circumferences of the flanges 7, 7', and 8'are provided with trapezoidal outer screws which are respectively engaged with the flange 4 and the outer hoop 9 which are provided with trapezoidal inner screws. If only a definite angle is rotated, the flanges can be tightened; meanwhile, sealing rings are arranged on flange surfaces for pressurizing and sealing the through holes of tight pressure. The utility model has the advantages of uniform stress, compact structure, and convenient operation; the rapid disconnection flange with a screw engagement can be used in a structure that pressure vessels need to be rapidly opened.

Description

Rapid disconnection flange with screw engage

The utility model relates to the flange that solid packing is arranged between relatively-stationary sealing surface.

Opening flange soon is the requisite a kind of structure of pressure vessel industries, and it is had many uses, and this structure is particularly useful for the frequent occasion of loading and unloading material of opening, as: autoclave, disinfection tank, cooking pot, high temperature-pressure dyeing machine, dipping still etc.The flange of existing these structures all adopts the monodentate engagement, the subject matter of its existence is: because the force-bearing situation of monodentate is poor, the profile of tooth of designing is not only wide but also high, cause whole flange arrangement very huge, waste material, cost height, use are also inconvenient, and root stress is concentrated, occurs crackle easily.

The purpose of this utility model is: it provides a kind of quick open type flange of thread engagement, and it is stressed rationally, can overcome existing problem in the background technique.

Below in conjunction with accompanying drawing, provide the technical solution of the utility model and embodiment.

Fig. 1, erection drawing of the present utility model;

Fig. 2, I partial enlarged drawing of the present utility model;

Fig. 3, be I partial enlarged drawing A-A sectional drawing;

Fig. 4, II partial enlarged drawing of the present utility model.

It comprises the utility model: as shown in Figure 1 and Figure 2, with end socket 3 flange connecting 4, and between cylindrical shell 2 flange connecting 7, two flanges seal ring 5 is housed; As Fig. 1, shown in Figure 4, with end socket 1 flange connecting 7 ', be equipped with between cylindrical shell 2 flange connecting 8, two flanges seal ring 5 ', connect with outer hoop 9.Flange 7 and 7 ', symmetric arrangement has male and fomale(M﹠F) around 8, as shown in Figure 3, has trapezoidal thread around the protuberance of male and fomale(M﹠F), respectively with the flange 4 that has trapezoidal internal thread, bind round 9 outward and be meshing with each other.Open or when closing end socket, as long as rotate to an angle (generally being not more than 30 °) relatively.Flange 7,7 ' the end face groove on be equipped with respectively seal ring 5,5 ', and have separately give compaction forces through

hole

6,6 '.During use, as long as mix the locking device that prevents that the flange pine from moving back, and give earlier through hole 6,6 ' carry out pressurising implemented sealing after, can carry out normal running.

The utility model is compared with background technique, and the useful effect that has is:

1. stressed even, safe and reliable, the life-span is long;

2. compact structure is in light weight, and consumptive material is few, and cost is low, and is easy to operate.

Therefore, can in the structure that pressurized container need be opened soon, promote the use of.

Claims

A kind of thread engagement is opened flange soon, it comprise with end socket [3] flange connecting [4], with cylindrical shell [2] flange connecting [7], seal ring [5]; With end socket [1] flange connecting [7 '], with cylindrical shell [2] flange connecting [8], seal ring [5 '], outer hoop [9]; Feature of the present utility model is: flange [7] and [7 '], [8] protuberance of the male and fomale(M﹠F) of symmetric arrangement all around have trapezoidal outside thread on every side, are meshing with each other with the flange that has trapezoidal internal thread [4], outer hoop [9] respectively.
