Abstract
The invention discloses a thermal expansion elimination device. The device comprises a sealing surface (1), a sealing ring (2), disc springs (3 and 5), adjusting nuts (4 and 6) and an engine body (7), wherein the sealing surface (1) is arranged on one side of the engine body (7); the sealing ring (2) is arranged on the other side of the engine body (7); a slip plane is formed between the sealing surface (1) and the sealing ring (2); the disc spring (3) and the adjusting nut (4) are arranged on the sealing surface (1); and the disc spring (5) and the adjusting nut (6) are arranged on the engine body (7). In the thermal expansion elimination device, the slip plane is arranged at the top point of an L-shaped part, so that the device can be freely stretched and retracted during axial expansion and is fixed together with an axial vertical part; two parts on the slip plane slip relative to each other to eliminate the dynamic stretching amount; and certain pressure is applied to the slip plane through the disc springs and is closed loop pressure, so that other parts cannot be influenced by the applied pressure, and a good sealing effect is ensured.
Description
Technical field
The present invention relates in the petrochemical industry extruder body in the extruder grain unit when heating cooling and technological temperature adjustment, the elimination problem that the body axial length dimension that causes because of variations in temperature changes relates in particular to a kind of thermal expansion cancellation element.
Background technology
The extruder grain unit is divided into linear pattern and L type by apparatus arrangement in the petrochemical industry, and linear pattern is exactly that Squeezinggranulator and follow-up granulating system are arranged point-blank; The L type is exactly Squeezinggranulator and follow-up vertical layout of granulating system; The thermal expansion of straight line type is bigger than L type arranged type; But the length variations of this situation only on a line, can solve easily, and the thermal expansion that the L type is arranged is mainly reflected on the flex point of L; But also be dynamic, the thermal expansion amount of this point is bad eliminating.
Summary of the invention
The thermal expansion cancellation element that the purpose of this invention is to provide the thermal expansion problem of the extruder grain system that a kind of L of can solve type arranges.
The present invention for realizing the technical scheme that above-mentioned purpose adopted is: a kind of thermal expansion cancellation element; Comprise sealing surface (1), sealing ring (2), dish spring (3; 5), adjusting nut (4,6) and body (7), said sealing surface (1) is installed in a side of body (7); Sealing ring (2) is installed in the opposite side of body (7); Constitute a slide surface between said sealing surface (1) and the sealing ring (2), dish spring (3) and adjusting nut (4) are installed on the sealing surface (1), and dish spring (5) and adjusting nut (6) are installed on the body (7).
When causing body axial direction length variations, produce between sealing surface (1) and the sealing ring (2) and relatively move, body axial direction length variations is eliminated when variations in temperature.
A kind of thermal expansion cancellation element of the present invention, the place, summit in that the L type is arranged is provided with a slide surface; Make axial free expanding flexible, fixed with axial vertical member, produce relatively between slide surface place two parts and slide; This dynamic stroke is eliminated, on slide surface, utilize the dish spring to apply certain pressure then, and if closed loop of this pressure; Make other parts not influenced by applied pressure, guarantee good sealing effectiveness.

Among the figure: 1, sealing surface; 2, sealing ring; 3, dish spring; 4, adjusting nut; 5, dish spring; 6, adjusting nut; 7, body.
The specific embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, the thermal expansion cancellation element comprises sealing surface 1, sealing ring 2, dish spring 3, dish spring 5, adjusting nut 4, adjusting nut 6 and body 7; Sealing surface 1 is installed in a side of body 7, and sealing ring 2 is installed in the opposite side of body 7, constitutes a slide surface between sealing surface 1 and the sealing ring 2; Dish spring 3 is installed on the sealing surface 1 with adjusting nut 4, and dish spring 5 is installed on the body 7 with adjusting nut 6, when the body axial length dimension that causes because of variations in temperature; Just produced between the sealing surface 1 of slide surface both sides and the sealing ring 2 and relatively moved; So just eliminate the variation of axial direction length, simultaneously owing to have certain normal pressure and softer sealing ring double action between slide surface, during practical application; Can remove to adjust the adjustment nut at dish spring place according to on-the-spot various conditions; Thereby regulate the size of positive pressure value, reach good sealing effectiveness, finally eliminated thermal expansion amount.
Claims (2)
1. thermal expansion cancellation element; It is characterized in that: comprise sealing surface (1), sealing ring (2), dish spring (3; 5), adjusting nut (4,6) and body (7), said sealing surface (1) is installed in a side of body (7); Sealing ring (2) is installed in the opposite side of body (7); Constitute a slide surface between said sealing surface (1) and the sealing ring (2), dish spring (3) and adjusting nut (4) are installed on the sealing surface (1), and dish spring (5) and adjusting nut (6) are installed on the body (7).
2. a kind of thermal expansion cancellation element according to claim 1; It is characterized in that: when causing body axial direction length variations when variations in temperature; Produce between sealing surface (1) and the sealing ring (2) and relatively move, body axial direction length variations is eliminated.
