Description
Technical field
The utility model relates to a kind of for the connection valve in oil and gas well drilling operation.
Background technique
In existing oil, natural gas extraction operation, pipeline is due to frequent conversion, and the connection valve of connecting tube is very important, and existing connection valve mostly is flange-type structure, connects once generation overpressure or security incident cannot disconnect pipeline in time.
Pressure gauge with electric contact is commonly called as alarm pressure gauge, and it arrives the upper limit of setting at the liquid detected or gas pressure or prescribes a time limit down, can sound the alarm to point out.
Summary of the invention
In order to solve the not high deficiency of existing connection valve Security, the utility model provides a kind of high security connection valve.
The utility model solves the technological scheme that its technical problem adopts: the valve body of high security connection valve is logical structure in inverted T-shaped, one word passage of described valve body is main transmission channel, the adjustment passage of described valve body is provided with the end cap of Intermediate Gray tapped hole, be provided with a lower end and main transmission channel in described adjustment passage seal and end block with regulating the screw shaped of channel seal around, described cut-off block is provided with a screw rod, screw thread on described screw rod coordinates with the tapped hole in end cap, described end cap is provided with the rubber pad of a centre by screw rod, screw rod above described rubber pad is provided with a nut matched with screw surface screw thread, a cross-brace is connected with above described screw rod, described main transmission channel is connected with a pressure channel, described pressure channel and an alarm pressure list catenation, a switch valve is provided with between described pressure channel and alarm pressure gauge.
The alarm pressure gauge connected when the pressure channel lock in valve body detects that manifold pressure to reach on safety pressure in limited time, alarm pressure gauge gives the alarm, prompting manifold pressure is too high or too low, the position of cut-off block is regulated to regulate pressure size or closing passage by cross-brace, prevent danger, the switch valve on pressure channel can change alarm pressure gauge by closing passage when damaging appears in alarm pressure gauge.
The beneficial effects of the utility model are: the utility model has higher Security, corrosion resistance and high hardness, can the just prompting when danger is incipient.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is plan view of the present utility model.
