The anti-freezing liquid is filled in the pressure transmission pipe 10 and the rubber pipe 30.
Through setting up pressure transmission pipe, manometer erection joint, rubber tube and pillar, manometer erection joint and pressure transmission pipe intercommunication to can install the manometer on manometer erection joint. Through the one end intercommunication with the one end of pressure transmission pipe and rubber tube, the other end of rubber tube is confined, with the pillar suit outside the rubber tube, and with the one end of pillar with the one end of pressure transmission pipe be connected but not the intercommunication, after on being connected to the pipeline with the connection interface of the other end of pillar, because there is the clearance between the inner wall of pillar and the rubber tube, can extrude the rubber tube after the fluid in the pipeline gets into the pillar, because rubber tube and pressure transmission intraductal packing have antifreeze, the pressure of fluid extrusion rubber tube can be through the antifreeze to use in the manometer of installing on manometer erection joint, thereby can detect the interior fluidic pressure in the pipeline by the manometer. The anti-freezing liquid is filled in the pressure transmission pipe, the anti-freezing liquid cannot freeze at a lower environmental temperature, the freezing and solidification of the fluid in the pressure gauge are avoided, the fluid in the pipeline does not enter the pressure gauge, particle impurities are prevented from entering the pressure gauge, and the corrosion of the fluid to the inside of the pressure gauge is also avoided, so that the service life of the pressure gauge is prolonged, and the accuracy of pressure detection is ensured.
The connection interface 41 may be a threaded interface and the connection interface 41 may conform to the button type of the kill, choke manifold so that the pressure gauge buffer may be installed on the kill, choke manifold. The anti-freezing solution can bear the low temperature of minus 45 ℃ without solidification so as to ensure that the pressure can be accurately detected, an electric heating belt, a felt and the like are not needed to be used for anti-freezing, and the electricity safety risk is eliminated.
As shown in fig. 1, the pressure gauge mounting head 20 may have a valve 21 for controlling the on/off of the pressure gauge mounting head 20. Through opening valve 21, can make manometer erection joint 20 switch on, install the manometer on manometer erection joint 20 and can detect pressure, through shutoff valve 21, can make manometer erection joint 20 disconnection, the manometer stops to detect pressure. The pressure gauge can be disassembled and maintained after the valve 21 is closed, so that the anti-freezing solution is prevented from leaking, and the pressure gauge mounting joint 20 can also be used as an injection port of the anti-freezing solution before the pressure gauge is mounted on the pressure gauge mounting joint 20.
Optionally, the pressure transmission pipe 10 may further be provided with an antifreeze injection port for injecting antifreeze, and an exhaust port for exhausting air when injecting antifreeze. By arranging the independent antifreeze liquid injection port, antifreeze liquid can be injected from the antifreeze liquid injection port after the pressure gauge is installed, so that the pressure transmission pipe 10 and the rubber pipe 30 are filled with the antifreeze liquid, and the antifreeze liquid injection port and the exhaust port can be closed after the antifreeze liquid is injected, so that the pressure gauge is zeroed. The antifreeze liquid inlet and the antifreeze liquid outlet can be closed by screw plugs, or the antifreeze liquid inlet and the antifreeze liquid outlet can be welded.
As shown in fig. 1, the pressure gauge buffer may include two pressure gauge mounting fittings 20. Through setting up two manometer erection joints 20 for can install two manometers on the manometer buffer, the range of two manometers can be different when the installation. When detecting the pressure, only the valve 21 on the pressure gauge mounting connector 20 provided with the pressure gauge with a large range can be opened, and the valve 21 on the pressure gauge mounting connector 20 provided with the pressure gauge with a small range is opened after the pressure is ensured not to exceed the range of the pressure gauge with a small range through the pressure gauge with a large range to detect the pressure. The pressure gauge with the smaller measuring range generally has smaller division value and higher measuring precision, thus not only improving the measuring precision, but also avoiding the damage to the pressure gauge caused by the overlarge pressure in the pipeline exceeding the measuring range of the pressure gauge. Illustratively, a pressure gauge with a range of 0-10 MPa and a pressure gauge with a range of 0-60 MPa can be set.
In this embodiment, one end of the pressure transmission pipe 10 is connected to the rubber tube 30, and the other end of the pressure transmission pipe 10 and the middle of the pressure transmission pipe 10 are connected to a pressure gauge mounting joint 20. The pressure gauge mounting joints 20 are mounted at the end and the middle of the pressure transmission pipe 10, so that pressure gauges with different measuring ranges can be distinguished easily.
Alternatively, the pressure gauge mounting head 20 may have a tubular shape, and the pressure gauge mounting head 20 is connected to the pressure transmission pipe 10 by a screw thread, so as to be easily disassembled.

The pipe wall of the baffle pipe 50 is provided with a plurality of communicating holes 50a, the rubber pipe 30 is sleeved outside the baffle pipe 50, and a gap is formed between the inner wall of the rubber pipe 30 and the outer wall of the baffle pipe 50. Because a gap is formed between the inner wall of the rubber tube 30 and the outer wall of the baffle tube 50, the rubber tube 30 can be shrunk in space after being extruded, and the communicating hole 50a on the baffle tube 50 can keep the communication between the rubber tube 30 and the pressure transmission tube 10, so that the pressure can be transmitted to the pressure gauge smoothly. The blocking pipe 50 can limit the deformation degree of the rubber pipe 30, and avoid the damage of the local deformation of the rubber pipe 30.
In addition, baffle 50 may also function to limit the maximum pressure that can be detected. The maximum pressure that the manometer connected to the manometer buffer can detect is the pressure in the corresponding pipe when the rubber tube 30 is compressed to be completely attached to the outside of the baffle tube 50 and the gap between the rubber tube 30 and the baffle tube 50 disappears, and even if the pressure in the pipe exceeds the maximum pressure, the rubber tube 30 cannot be compressed continuously, so the pressure in the pressure transmission tube 10 cannot be increased continuously and the indication number of the manometer cannot be increased continuously. Based on this, when selecting the pressure gauge to be mounted on the pressure gauge mounting head 20, the maximum measurement value that can be measured by the pressure gauge with the largest measuring range selected can be equal to the maximum pressure or slightly greater than the maximum pressure, so that the measuring range of the pressure gauge can be fully utilized, and the pressure gauge is prevented from being damaged.
As shown in fig. 2, a plurality of communication holes 50a may be spaced apart in the axial direction of the baffle pipe 50. By arranging the plurality of communication holes 50a at intervals in the axial direction of the stopper pipe 50, even if a large local deformation of the rubber tube 30 blocks a part of the communication holes 50a, the pressure can be transmitted to the pressure gauge through the other communication holes 50 a.
Illustratively, the diameter of the communication holes 50a may be 4mm to 6mm, and the number of the communication holes 50a may be 6 to 8. In this embodiment, the diameter of the communication holes 50a is 4mm, and the number of the communication holes 50a is 6.
As shown in fig. 2, the pressure gauge buffer may further include a connection seat 60 having a tubular shape. One end of the connecting seat 60 is communicated with one end of the pressure transmission pipe 10, the other end of the connecting seat 60 is communicated with one end of the rubber pipe 30, and one end of the baffle pipe 50 is positioned in the connecting seat 60 and connected with the inner wall of the connecting seat 60. The rubber tube 30 and the stopper tube 50 can be easily connected to the pressure transmission tube 10 by providing the coupling seat 60.
Alternatively, the inner diameter of the middle portion of the coupling seat 60 may be smaller than the inner diameter of the end connected to the rubber tube 30, so that the blocking tube 50 may be inserted into the coupling seat 60, the end of the blocking tube 50 is connected to the middle portion of the coupling seat 60, and after the rubber tube 30 is coupled to the coupling seat 60, a gap may be formed between the inner wall of the rubber tube 30 and the outer wall of the blocking tube 50, so that the rubber tube 30 may have a space to be contracted.
As shown in fig. 2, one end of the pressure transmission pipe 10 is connected to one end of the connection holder 60, and one end of the protection pipe 40 may be coaxially connected to an outer wall of the other end of the connection holder 60. After the protection tube 40 is sleeved outside the connecting seat 60 and connected with the outer wall of the connecting seat 60, a gap is formed between the inner wall of the protection tube 40 and the rubber tube 30, so that fluid can enter the protection tube 40 to extrude the rubber tube 30.
Alternatively, both the pressure transfer tube 10 and the baffle tube 50 may be threadedly coupled to the coupling seat 60. The adoption threaded connection not only is convenient for seal, makes things convenient for the dismouting moreover, is convenient for maintain the manometer buffer.
Fig. 3 is a schematic structural diagram of a pressure detection apparatus provided in an embodiment of the present disclosure. As shown in fig. 3, the pressure sensing means may include a pressure gauge 70 and a pressure gauge buffer as shown in fig. 1, the pressure gauge 70 being mounted on the pressure gauge mounting nipple 20.
By providing a pressure gauge buffer and a pressure gauge, the pressure gauge can be mounted on a pressure gauge mounting adapter of the pressure gauge buffer. Through the one end intercommunication with the one end of pressure transmission pipe and rubber tube, the other end of rubber tube is confined, with the pillar suit outside the rubber tube, and with the one end of pillar with the one end of pressure transmission pipe be connected but not the intercommunication, after on being connected to the pipeline with the connection interface of the other end of pillar, because there is the clearance between the inner wall of pillar and the rubber tube, can extrude the rubber tube after the fluid in the pipeline gets into the pillar, because the packing of rubber tube and pressure transmission pipe has antifreeze, the pressure of fluid extrusion rubber tube can be used to the manometer through antifreeze, thereby can detect the interior fluidic pressure of pipeline by the manometer. The anti-freezing liquid is filled in the pressure transmission pipe, the anti-freezing liquid cannot freeze at a lower environmental temperature, the freezing and solidification of the fluid in the pressure gauge are avoided, the fluid in the pipeline does not enter the pressure gauge, particle impurities are prevented from entering the pressure gauge, and the corrosion of the fluid to the inside of the pressure gauge is also avoided, so that the service life of the pressure gauge is prolonged, and the accuracy of pressure detection is ensured.
