Abstract
The utility model relates to an oil injecting and draining valve for high voltage electric devices, which is an associated device for electric power system high voltage transform devices and comprises a valve body, an oil draining nozzle, a spherical valve core, sealing rings, and a spring. The utility model is characterized in that the lower part of a valve hood is connected with a valve seat and is sealed by the sealing ring; the valve body is fully in the valve hood and the valve seat; the lower part of the valve body is connected with the valve seat and is sealed by the sealing ring in a groove of the valve seat, so that double seal is realized. The utility model has the advantages of the valve body is fully sealed in the valve hood and the valve seat for double seal, so that sunlight irradiation can be prevented. Even if the utility model is used for a long time, the phenomenon of oil leakage can not occur. Under equal conditions, the service lives of rubber rings can be extended by more than one time, and the maintenance quantity can be reduced.
Description
The utility model relates to a kind of high voltage electric equipment notes, oil discharging valve, is electric power system high-tension transformation equipment match equipment.
The fuel tap door that uses on the high-tension transformation equipment can be drained the oil according to how much adopt the oil nozzle body or the aciculiform oil nozzle of the amount of draining the oil at present, and is time saving and energy saving, convenient, flexible, but the shortcoming that exists is that spool is a cone shape, in use easily bumps partially, causes the consequence of leakage of oil.And spherical valve core has solved this problem, but uses over a long time, has the oil impregnate phenomenon at valve seat and high-tension transformation equipment connection part, increases maintenance load.
The purpose of this utility model is to provide at the technical problem of above-mentioned existence a kind of valve body in valve bonnet and valve seat are totally-enclosed, and the high voltage electric equipment of realizing double seal is annotated, oil discharging valve.
The purpose of this utility model is achieved through the following technical solutions:
It includes valve body, the mouth of draining the oil, spherical valve core, seal ring, spring, it is characterized in that the valve bonnet bottom is connected with valve seat, and is sealed by seal ring, valve body is totally-enclosed in valve bonnet and valve seat, the bottom of valve body is connected with valve seat, by the sealing of the seal ring in the valve seat groove, thereby realizes double seal.
The utility model has the advantages that valve body is totally-enclosed in valve bonnet and valve seat, double seal can prevent solar radiation, even the oil impregnate phenomenon does not take place long-term the use yet, under equal conditions, can prolong cushion rubber working life more than one times, reduces amount of maintenance.
Fig. 1 is the utility model structural representation.
Describe the utility model in detail below in conjunction with accompanying drawing:
As shown in Figure 1, drain the oil mouth 9 and aciculiform oil are housed on the valve body 8 chew 11, be provided with spring 4 below the spherical valve core 6, O-ring seal is 7,10,12, valve body 8 bottoms are provided with screw thread and are threaded with valve seat 1, and cushion rubber 2 is located at sealing in valve seat 1 groove, and valve bonnet 5 bottoms are threaded with valve seat 1 and are sealed by cushion rubber 3.
