Problems solved by technology

This method is old-fashioned, and the production efficiency is low, and mercury is a very volatile substance. Excessive inhalation of mercury by the human body will lead to mercury poisoning. Therefore, the mobility of operators in this process is very high.
At the same time, when filling manually, the filling volume is different each time, which leads to the time-consuming and laborious work of the next approval process

Embodiment Construction

[0009] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0010] Such as figure 1 As shown, a mercury sphygmomanometer filling equipment includes a lead bucket 1, a switch 2, a mercury cup 3, a scale 4, and a filling device 5. Mercury can react with various metals, but not with lead and plastics, so the materials used in the present invention are lead and plastics. The lead barrel 1 is used to store mercury during transportation, and generally has a relatively large volume. Lead the lead barrel 1 to an outlet, and there is a switch 2 at the outlet, and the mercury flows into the mercury cup 3 through a plastic tube. The side of the mercury cup 3 is equipped with A scale meter 4, through which the amount of mercury in the mercury cup 3 can be known. There is an opening at the lower end of the mercury cup 3, which is connected to the mercury inlet hole 7 of the valve seat in the filling device 5 through a rubber...

Abstract

The invention discloses a quantitative filling device and relates to a quantitative filling device for various kinds of liquid matters. With mercury filling of a mercury sphygmomanometer as an example in the embodiment of the invention, the quantitative filling device comprises a valve seat, a valve plug, a base plate, a cylinder, an adjusting screw, an input-output hose and a mercury cup, wherein the valve plug is provided with a quantitative groove, therefore, the quantity of mercury filled in each mercury sphygmomanometer is definite; and the valve plug is arranged inside the valve seat, and the valve plug and the valve seat are matched with high precision, therefore, the mercury does not leak. The valve seat is fixed on the base plate, the cylinder is fixed on the base plate, and the valve plug moves back and forth under the drive of the cylinder. The mercury cup is arranged at the upper part of a filling unit, the mercury is introduced into the valve plug through a rubber pipe, meanwhile, the cylinder is controlled by adopting a single chip microcomputer, the time of staying before and behind the valve plug can be set, and the intelligentizing degree of the quantitative filling device can be greatly improved.

Description

technical field [0001] The invention relates to a device capable of quantitatively filling various liquid substances, in particular to a device capable of quantitatively filling mercury sphygmomanometers. Background technique [0002] At present, on the production line of mercury sphygmomanometers, the process of filling mercury is still manually filled with mercury through a funnel. This method is old-fashioned, and the production efficiency is low, and mercury is a very volatile substance. Excessive inhalation by the human body will lead to mercury poisoning. Therefore, the mobility of the operators in this process is very large. At the same time, when filling manually, the filling volume is different each time, which leads to the time-consuming and laborious work of the next approval process. Contents of the invention [0003] The purpose of the present invention is to adopt quantitative, sealed and non-leakage design to ensure consistent mercury filling volume each ti...
