Description
Technical field
The utility model belongs to power equipment, particularly a kind of vacuum eccentric valve plate combination seal formula transformer butterfly valve.
Background technique
Transformer butterfly valve is one of capital equipment of transformer oil circuit control, butterfly valve in the past adopts O type ring as sealed member usually, easily be corroded decomposition, working life is short, valve body many employings cast member, seepage is relatively more serious, needs often to change during use, both wasting manpower and material resources, affects again the normal operation of equipment.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of structure simple, long service life, vacuum with low cost eccentric valve plate combination seal formula transformer butterfly valve.
The technological scheme that the utility model technical solution problem adopts is: vacuum eccentric valve plate combination seal formula transformer butterfly valve comprises valve body, valve rod, handle, spring, ball, be characterized in that valve rod is installed in the eccentric opening of valve body, the copper sheathing of location is installed in the positioning center hole of valve body upper end, the lower end of valve rod is installed in the positioning center hole of valve body lower end, with the sealing of O RunddichtringO between valve rod and valve body, be fixedly connected with two screws between valve rod with valve plate, inlay in the endoporus of valve body left side and alloy seal circle is housed, valve plate is connected with the Contact of alloy seal circle and seals, the upper tip of valve rod is set with handle, on the right side of valve body upper-end surface, spring seat is fixedly equipped with in the position of corresponding valve rod upper tip, in spring seat, spring is equipped with on right side, ball is equipped with in the left side of spring, the groove that the left side of ball is placed in handle right side is spacing.
The beneficial effects of the utility model are: vacuum eccentric valve plate combination seal formula transformer butterfly valve can ensure the accurate positioning of valve plate and valve body, realizing valve plate opens smooth and easy, and structure good processability, burn into is not wear-resistant, non-leakage, good seal performance, greatly increase the service life, Environmental Conditions and temperature range are increased greatly, reduces and change number of times, greatly saved the maintenance in later stage and the man power and material of replacing.
Accompanying drawing explanation
