Description
Technical Field
The utility model relates to a fixed ball valve, especially a blowdown liquid structure of fixed ball valve.
Background
When a fixed ball valve is designed, a sewage discharge outlet is often arranged on a valve body for the purpose of realizing the sewage discharge inside the valve. The blow-down valve for blow-down is located at 45 deg. below the valve body, which causes inconvenience in processing. The blowdown valve is installed and is also do not favorable to the blowdown at 45 orientations, and the inside pollutant of valve body is because receiving the influence of gravity to gather under the valve body, can not be through 45 blowdown export exhaust of below.
Disclosure of Invention
In order to overcome the prior art problem, the utility model provides a plug screw structure for blowdown liquid of fixed ball valve.
the technical scheme of the utility model, a plug screw structure for blowdown liquid of fixed ball valve, including the bottom shaft, the bottom shaft is connected with the valve body, be equipped with plug screw hole on the bottom shaft, the plug screw body is equipped with in the plug screw hole, the plug screw body is equipped with blowdown liquid hole, the blowdown liquid hole is under the narrow width shape, the blowdown liquid hole is equipped with the steel ball, the steel ball passes through plug screw head switch and forms sealedly with blowdown liquid hole.
The beneficial effects of the utility model are that, this structure is located the valve lower and installs on the bottom shaft, can the inside foul solution of clean valve, and it is more convenient to process.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
Fig. 2 is a partial schematic view of the structure of the present invention.
In the figure: 1. a valve body; 2. a bottom shaft; 3. a plug body; 4. a steel ball; 5. the head of the screw plug is opened and closed.
Detailed Description
As shown in fig. 1 and 2, the plug screw structure for blowdown liquid of the fixed ball valve comprises a bottom shaft, wherein the bottom shaft is connected with a valve body, a plug screw hole is formed in the bottom shaft, a plug screw body is arranged in the plug screw hole, the plug screw body is provided with a blowdown liquid hole, the blowdown liquid hole is narrow at the top and wide at the bottom, a steel ball is arranged in the blowdown liquid hole, and the steel ball forms a seal with the blowdown liquid hole through a plug screw head switch.
When the valve needs to discharge sewage, the screw plug head switch can be screwed out of the screw plug by a tool, and then the steel ball is taken out to discharge sewage. And after successful sewage discharge, screwing the steel ball through a screw plug switch to form sealing between the steel ball and the sewage discharge hole. Because this structure is located the valve minimum and installs on the bottom shaft, can the inside foul solution of gathering in the valve body below by the action of gravity of drain valve, and it is more convenient to process.
