Abstract
The utility model relates to an oxygen ball valve. A right valve body and a left valve body constitute a valve shell. A valve rod is arranged on the upper part of the right valve body. The upper end of the valve rod is connected with a drive device and the lower end of the valve rod is connected with ball body. A stuffing material is arranged on the valve rod and the stuffing material is provided with a lining ring, a roll flange and a locating block at the upper side. The ball body is arranged inside the right valve body and a gasket is arranged at the joint of the right valve body and the left valve body. The utility model is characterized in that a groove is respectively arranged on the right valve body and the left valve body, and a valve seat is arranged inside the groove. An O-shaped ring is arranged at the central section of the valve rod and a static spring is arranged on the bottom of the ball body. All the performance indexes of the utility model reach the national standards, for example, the sealability conforms to the stipulation of National Standard GB/T13927. Under a normal-temperature working condition, the useful time of the ball valve is larger than 20 thousand times and is a super-quality ball valve conforming to the stipulation of the grading standard JB/TQ 409 for the quality of ball valves. The utility model is applicable to special working conditions in which inflammable and explosive oxygen as well as other media are adopted.
Description
Technical field
The utility model relates to a kind of ball valve, particularly a kind of ball valve that is used for the oxygen medium.
Background technique
At present, existing ball valve is because of being subjected to the restriction of valve sealing structure and corresponding sealing material thereof, to inflammable and explosive medium incompatibilities such as oxygen.China Patent No. 200620070524.9 discloses a kind of oxygen ball valve, and there is following shortcoming in it: 1, valve itself does not have fire resisting construction.2, the electrostatic prevention structure of valve itself does not meet relevant national standard.3, the valve body inner flow passage does not carry out machining.4, valve is to go up dress formula structure, and complex structure is installed difficulty.5, all parts that valve is not described need carry out the oil removing degreasing.
Summary of the invention
The purpose of this utility model just provides a kind of ball valve that can adapt to inflammable and explosive media such as oxygen use.
The utility model can be realized by following mode: right valve barrel and left valve barrel are formed the shell of ball valve, valve rod is contained in right valve barrel top, and the valve rod upper end is connected with drive unit, and the valve rod lower end is connected with spheroid, filler is housed on the valve rod, lining ring is housed above the filler, rolls orchid and positioning block, spheroid is contained in the right valve barrel, and pad is equipped with in right valve barrel and left valve barrel joint, described right valve barrel and left valve barrel are provided with groove, valve seat is housed in the groove, and O shape circle is equipped with at the valve rod middle part, and the static spring is equipped with in the spheroid bottom.
Described drive unit is manual operating device, worm gearing, pneumatic actuating device or electric performance device.
Described O shape circle is to make with fluorine rubber.
The requirement that every performance index of the present utility model all are up to state standards meets the regulation of GB GB/T13927 as sealability, and under the normal temperature operating mode, meet the high-class product of ball valve quality grading standard JB/TQ409 regulation greater than 20,000 times working life.The utility model is applicable to needs to adopt the special operation condition occasion of inflammable and explosive media such as oxygen to use.
