Description
Technical Field
The utility model relates to a manometer installation technical field, concretely relates to prevent leaking manometer switching device.
Background
In the oil piping system of thermal power factory, can be equipped with a large amount of manometers to real time monitoring system ensures the stability and the security of system operation.
At present, when the manometer was installed, the manometer was directly connected with oil piping system's manometer sample connection, and the drawback that this kind of mode exists is: after the pressure gauge is used for a long time, the probability of oil leakage is increased, and because the pressure gauge is directly connected with a pressure gauge sampling port of an oil way system, the pressure gauge sampling port and the oil way system cannot be cut off in time to prevent leakage, a large amount of oil leakage can be caused, and fire or environmental pollution accidents are easy to happen.
SUMMERY OF THE UTILITY MODEL
In view of this, the present invention provides an adapter for a leak-proof pressure gauge to reduce oil leakage.
The utility model discloses an above-mentioned problem is solved to following technical means: the utility model provides a prevent leaking manometer switching device, is including manometer connecting pipe, intervalve and the sample connection pipe that communicates in proper order, the manometer connecting pipe is manometer connecting pipe oil inlet with the one end of intervalve intercommunication, there is the ball valve through spring coupling in the intervalve, processing of manometer connecting pipe oil inlet department has the cambered surface that matches with the ball valve is sealed.
Furthermore, a supporting plate connected with a spring is fixedly arranged in the sampling port connecting pipe, and an oil passing hole is formed in the supporting plate.
Furthermore, one end of the pressure gauge connecting pipe, which is far away from the middle pipe, is in threaded connection with the pressure gauge.
Furthermore, one end of the sampling port connecting pipe, which is far away from the middle pipe, is in threaded connection with a pressure gauge sampling port of the oil way system.
Furthermore, the pressure gauge connecting pipe, the middle pipe and the sampling port connecting pipe are in threaded connection.
The utility model has the advantages that: the utility model provides a prevent leaking manometer switching device, including manometer connecting pipe, intervalve and the sample connection pipe that communicates in proper order, the manometer connecting pipe is manometer connecting pipe oil inlet with the one end of intervalve intercommunication, there is the ball valve through spring coupling in the intervalve, processing of manometer connecting pipe oil inlet department has the cambered surface that matches with the ball valve is sealed. Adopt the manometer switching device of this application, when the manometer appears leaking, under the pressure difference effect, spring force can be overcome to high-pressure side pressure, promote ball valve and the sealed laminating of cambered surface and block up manometer connecting pipe oil inlet to the leakage of oil that has significantly reduced, simultaneously, has reduced the risk that the conflagration takes place, has reduced environmental pollution.
Drawings
The invention is further described with reference to the following figures and examples.
Fig. 1 is a schematic diagram of an embodiment of the present invention.
Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings, as shown in fig. 1: the utility model discloses a prevent leaking manometer switching device, including threaded connection's manometer connecting pipe 1, intervalve 2 and sample connection pipe 3 in proper order, adopt threaded connection's mode, mutual dismantlement between the three of being convenient for. The pressure meter connecting pipe is characterized in that one end of the pressure meter connecting pipe 1 communicated with the middle pipe 2 is a pressure meter connecting pipe oil inlet 8, the other end of the pressure meter connecting pipe is in threaded connection with a pressure meter, a ball valve 7 is connected into the middle pipe 2 through a spring 6, a cambered surface hermetically matched with the ball valve 7 is processed at the pressure meter connecting pipe oil inlet 8, the spring 6 is supported through a supporting plate 4 fixed in the sampling port connecting pipe 3, and an oil passing hole 5 is formed in the supporting plate 4. The sampling port connecting pipe is in threaded connection with a pressure gauge sampling port of the oil circuit system.
When normally using, ball valve 7 does not block up manometer connecting pipe oil inlet 8, and fluid flows through in proper order behind sample connection pipe 3, intervalve 2 and the manometer connecting pipe 1 and communicates with the manometer, makes things convenient for the manometer to carry out the oil pressure and measures, and at this moment, the oil pressure in sample connection pipe 3, intervalve 2 and the manometer connecting pipe 1 is the same. When the manometer leaked, can make the pressure in the manometer connecting pipe 1 reduce in the twinkling of an eye, thereby make the oil pressure difference appear between interior pipe 2 and the manometer connecting pipe 1, be the oil pressure high pressure side in the interior pipe 2, be the oil pressure low pressure side in the manometer connecting pipe 1, under the pressure difference effect, spring 6 elasticity can be overcome to high pressure side pressure, promote ball valve 7 and the sealed laminating of cambered surface and block up manometer connecting pipe oil inlet 8, thereby the leakage of oil has significantly reduced, and simultaneously, the risk that the conflagration took place has been reduced, environmental pollution has been reduced. After the oil leakage of the pressure gauge, the oil circuit system is closed, the pressure gauge is replaced, along with the closing of the oil circuit system, the pressure in the middle pipe 2 and the pressure gauge connecting pipe 1 gradually tends to be equal, the ball valve 7 is pulled by the spring 6 to reset, the oil inlet 8 of the pressure gauge connecting pipe is opened, the oil circuit is conducted, and the normal sampling of the pressure gauge is facilitated.
To sum up, adopt the manometer switching device of this application, when the manometer appears leaking, under the pressure difference effect, spring force can be overcome to high-pressure side pressure, promote ball valve and the sealed laminating of cambered surface and block up manometer connecting pipe oil inlet to the leakage of oil that has significantly reduced, simultaneously, reduced the risk that the conflagration takes place, reduced environmental pollution.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
