Abstract
The utility model discloses a quick open blind plate for a chemical industry, petroleum and natural gas pipe or a container. The utility model is composed of a rocking handle, a trivalve type clamping band, a hinge, a flange, an end cover, a safety pin and a pivot shaft. The trivalve type clamping band is divided into three clacks according to 120 DEG. One clack at the lower part is connected with the two clacks at the upper part through the hinge. The two clacks at the upper part are controlled by the rocking handle, which leads the left clack and the right clack at the upper part to be separated or closed. The utility model has the advantages of high safety and reliability, convenient operation, and quick open and close.
Description
What the utility model related to a kind of chemical industry, oil, natural gas line or container opens the region between the heart and the diaphragm plate soon.
The existing the region between the heart and the diaphragm of opening soon of chemical industry, oil, natural gas line or container that is applicable to is pulled, the employing two lobe formula clips that have open and close the region between the heart and the diaphragm plate door, the employing dentation conical ring clip that has opens and closes the region between the heart and the diaphragm plate door, its shortcoming is that the region between the heart and the diaphragm plate door is easily entangled firm, it is big to open and close the region between the heart and the diaphragm plate door operation labor intensity, can not rapidly opened and closed the region between the heart and the diaphragm plate door, and Safety performance is relatively poor.
What the purpose of this utility model provided a kind of chemical industry, oil, natural gas line or container opens the region between the heart and the diaphragm plate soon, thisly opens soon that the region between the heart and the diaphragm plate Safety performance is reliable, easy to operate, labor intensity is little, can be rapidly opened and closed.
The utility model purpose is achieved in that the utility model is made up of rocking handle, three-clove style clip, hinge, flange, seal ring, end cap, safety pin, pivot, it is characterized in that: the three-clove style clip is divided into three lobes by 120 °, below a lobe be connected with top two lobes by hinge, above two lobes control by rocking handle, above left and right two lobes separately or closed, a lobe is done thereupon and is moved up and down below driving.End cap is provided with seal ring and safety pin, can play good seal action, after the complete closure of three-clove style clip, plugs the safety pin that places on the end cap, and rocking handle and three-clove style clip can not shake and open and close.Flange and end cap are done 180 ° and are freely rotated by pivotally connected, and the three-clove style clip links to each other with flange, by rocking handle control, in order to banding flange and end cap.
The utility model is by top two lobes of rocking handle control three-clove style clip, below a lobe do thereupon and move up and down, thereby available have gentle hands just can be opened, closed end cap, easy to operate; End cap is provided with seal ring and safety pin, and the Security that makes it to operate is more reliable.
The utility model Safety performance is reliable, easy to operate, labor intensity is little, can be rapidly opened and closed.
Provide accompanying drawing of the present utility model below.
