In the prior art, the inner diameter of a pipeline of a discharge opening is gradually narrowed, a discharge opening sealing plug 1a is gradually screwed in according to threads 2a, and a rubber ring 3a at the bottom end of the sealing plug is gradually clamped, so that the sealing effect is achieved, and the attached drawing 1 is shown.

Above-mentioned discharge opening A sealed stopper is at the in-process of using, often does not know whether sealed the completion, in order to ensure sealedly, the operator has twisted the head with discharge opening sealed stopper 1a, has caused very big tension for discharge opening A pipeline, and reation kettle B (including the discharge opening) often is the glass preparation, and long-time high strength tension causes discharge opening pipeline glass's damage very easily.

In order to solve the problems, some reaction kettle manufacturers make marks on the discharge port sealing plug, and refer to fig. 2, the mark 4a is made on the glass pipeline of the discharge port A of the reaction kettle B, and the position to be screwed is the coincidence position of the two marks 4 a. However, after the sealing plug of the discharge opening A is inserted into the discharge opening, an operator sees the marked line refracted by the pipeline glass of the discharge opening, and deviation is generated on the position; the discharge opening is often positioned at a lower position, so that an operator can align the marked lines by squatting for observation, and operation is inconvenient; in addition, when the reaction is carried out at different temperatures, the optimal sealing positions are different due to the expansion caused by heat and the contraction caused by cold of the material of the reaction kettle, and a single marking line is difficult to cover.

SUMMERY OF THE UTILITY MODEL

The utility model provides a discharge opening sealing plug aims at solving the problem that the stopper is difficult to the accurate positioning among the prior art.

In view of the deficiency of the prior art, the technical scheme provided by the utility model is as follows:

the utility model provides a reation kettle discharge opening sealing plug, includes the sealing plug body, sealing plug body rear end is equipped with the external screw thread with discharge opening internal thread looks adaptation, its characterized in that, the screw thread of external screw thread on be equipped with the serial number, external screw thread periphery cover is equipped with the holding ring, the holding ring be equipped with the bolt hole, the bolt hole connection has the bolt, the holding ring on still be equipped with the window that is used for observing the serial number.

Furthermore, the above sealing plug for the discharge opening of the reaction kettle is characterized in that an anti-skid layer is arranged on the external thread, and the anti-skid layer is matched with the head of the bolt.

Furthermore, the sealing plug for the discharge opening of the reaction kettle is characterized in that a sealing gasket is arranged at the upper end of the sealing plug body.

Further, the numbers of the sealing plugs for the discharge opening of the reaction kettle are sequentially arranged from top to bottom according to the sequence of Arabic numbers from small to large.

The utility model provides a pair of technical scheme operator according to the digit of serial number, can confirm the position that the location needs to be twisted fast through the holding ring, the location is accurate, convenient operation to can effectively solve the different problem in best sealed position that expend with heat and contract with cold and lead to, convenient to use can not confirm the position when avoiding the operator to twist and move, excessively twist many times and move and make the long-time high strength tension of reation kettle, cause discharge opening pipeline glass's damage.

Detailed Description

The following claims of the present invention are further detailed in conjunction with the detailed description and the accompanying drawings, but are not intended to limit the invention in any way.

The utility model provides a sealing plug for a discharge opening of a reaction kettle, referring to figures 4-6, which comprises a sealing plug body 1, wherein the sealing plug body 1 is cylindrical, the rear end of the sealing plug body 1 is provided with an external thread 2 matched with the internal thread of the discharge opening, the periphery of the external thread 2 is sleeved with a positioning ring 4, the positioning ring 4 is provided with a bolt hole 41, the bolt hole 41 is connected with a bolt 42, the positioning ring 4 is fixed on the discharge opening A through the bolt 42,

the user loosens fixing bolt 42 earlier, and holding ring 4 is drawn to sealing plug body 1 bottommost, finds the best sealed position after, pulls up fixing ring 4 and supports discharge opening lower edge, screws up fixing bolt 42 again, is not loosening. In later use, the discharge opening sealing plug body 1 is screwed to the positioning ring 42 and tightly attached to the lower edge of the discharge opening A, so that good sealing performance can be ensured.
