Angle valve control device

Abstract

The invention relates to a valve opening and closing device, in particular to an angle valve operating device. Including the hand wheel, the hand wheel is connected with the long shaft, and the long shaft is connected with the sleeve, the right connecting shaft, the cross shaft universal coupling and the left connecting shaft in turn, the left connecting shaft is the input shaft of the spiral bevel gear rotating box, the spiral bevel The output shaft of the gear turning box is connected with the cross shaft universal joint; the pulling fork includes a shaft end with a long hole, a spring sleeve and a claw, and the shaft end of the pulling fork extends into the short shaft of the cross shaft universal joint. The shaft end and the short shaft are connected by a pin arranged in the oblong hole. A spring is provided outside the shaft end of the fork, and the spring withstands the end of the short shaft. The spring sleeve is sleeved on the outside of the short shaft and the spring. The spring sleeve The barrel is fixedly connected with the pulling claw of the pulling fork; the pulling claw passes through the opening disc, and the opening disc is provided with an angle hole matched with the angle valve. The invention can directly open and close the angle valve from the outside of the tank; the opening and closing of the angle valve is carried out in a closed space, which has good safety.

Description

Angle valve control device technical field The present invention relates to a kind of valve opening and closing device, relate in particular to be applied to isotope separation liquefaction material dumping operation and nucleus The highly reliable and leak-shielding angle valve control device is required in the gasification and reclaiming process of fuel production. Background technique In the isotope separation project, the 3m of UF6 is housed 3 (B) The container is heated in a pressure vessel (autoclave) to make the UF6 liquid Quantitatively dispensing into 30B containers to complete the safe dispensing of UF6; in the production engineering of nuclear fuel elements, quantitative dispensing is required The 30B container with UF6 is heated in the pressure vessel (vaporization tank) to vaporize UF6 and lead it into the corresponding process pipeline. The above operation In the process, it is necessary to ensure that critical safety accidents and cross-contaminatio...
