Detailed description of the invention
As shown in Figure 1, this utility model includes valve body 9, spheroid 14, valve rod 13 and valve rod overcoat 8, described spheroid 14 is arranged in valve body 9, the both sides of described valve body 9 are respectively and fixedly provided with side pipe 10, the inner of described side pipe 10 is positioned at valve body 9, it is provided with elastic sealing structure between described spheroid 14 and side pipe 10, the lower end of described valve rod 13 is through valve body 9 and fixing with spheroid 14 is connected, described valve rod overcoat 8 is arranged on outside valve rod 13, the lower end of described valve rod overcoat 8 is fixing with valve body 9 to be connected, and the upper end of described valve rod overcoat 8 is provided with coded lock.
As shown in Figure 1, described elastic sealing structure includes valve seat 18, skeleton the 16, first O 17 and disc spring 15, described skeleton 16 is arranged on the outside of valve seat 18, the periphery of described valve seat 18 is provided with the first seal groove, described first O 17 is arranged in described first seal groove and for sealing between valve seat 18 and side pipe 10, described disc spring 15 is arranged on the outside of skeleton 16, and the two ends of described disc spring 15 hold out against on skeleton 16 and side pipe 10 and promote the intimate of valve seat 18 and spheroid 14 to fit respectively.
As shown in Figure 1, it is provided with upper bearing (metal) 11-1 and gland 5 between top and the valve rod 13 of described valve rod overcoat 8, described gland 5 is positioned at the top of upper bearing (metal) 11-1, multiple second O 6 and gasket seal 7 it is arranged at intervals with between described gland 5 and upper bearing (metal) 11-1, second O 6 and gasket seal 7 are compressed by described gland 5 by jump ring 4, described jump ring 4 is positioned at the top of gland 5, and described jump ring 4 is arranged on valve rod 13; Second O 6, gasket seal 7 and gland 5 are set and can ensure that sealing.
As shown in Figure 1, being provided with lower bearing 11-2 and thrust washer 12 between bottom and the valve rod 13 of described valve rod overcoat 8, described thrust washer 12 is positioned at the lower section of lower bearing 11-2, and the setting of thrust washer 12 can increase sealing, when the pressure in floating ball valve is more high, then seal more reliable.
In the present embodiment, described upper bearing (metal) 11-1 and lower bearing 11-2 is sliding bearing, arranges sliding bearing and can reduce rotating torque between valve rod 13 and valve rod overcoat 8.
In the present embodiment, described coded lock is mechanical thumbwheel puzzle lock.
As it is shown in figure 1, dial-up dish 1 inwall of described mechanical thumbwheel puzzle lock is provided with the second seal groove, it is provided with the 3rd O 2 in described second seal groove, it is possible to waterproof and dustproof, substantially prolongs the service life of welding ball valve.
In the present embodiment, the connected mode of described side pipe 10 and valve body 9 is for welding.
In the present embodiment, the connected mode of described valve rod overcoat 8 and valve body 9 is for welding.
Operation principle of the present utility model is: during use, and by two side pipes 10 all and pipeline welding, the connection of ball valve or to block be realized by 90 degree of spinning balls 14,90 degree of rotation valve rods 13 can be opened or close welding ball valve clockwise or counter-clockwise. After setting password, when welding ball valve opened by needs, dial-up dish 1 must be rotated in the correct order forward or backwards, dial-up dish 1 drives the plectrum 3 of coded lock to tram, make buckle on plectrum 3 just can dismantle after coincideing with the draw-in groove on valve rod overcoat 8 dial-up dish 1, otherwise cannot opening operation welding ball valve, so effectively prevent offender's pirate of the open welding ball valve, stolen, steal cold water, steal the phenomenons such as hot water. Owing to being provided with elastic sealing structure between spheroid 14 and side pipe 10, therefore can ensure that welding ball valve double fluid is to all sealing. After welding ball valve completely closes, when pipeline pressure is higher, the power that spheroid 14 is pushed to rear side valve seat 18 by medium pressure itself is relatively big, is provided that enough sealing forces ensure to seal; When pipeline pressure is relatively low, the power that spheroid 14 is pushed to rear side valve seat 18 by the pressure of medium self is less, and now, the elastic force of disc spring 15 also pushes valve seat 18 to spheroid 14, to guarantee sealing effectiveness. Both sides valve seat 18 is when floating, and the axial seal between valve seat 18 and side pipe 10 is to be realized by the first O 17.
The above; it it is only preferred embodiment of the present utility model; not this utility model is imposed any restrictions; every any simple modification, change and equivalent structure transformation above example made according to this utility model technical spirit, all still falls within the protection domain of technical solutions of the utility model.
