Technical field
The utility model relates to Oil/gas Well exploitation construction equipment field, and particularly a kind of pressure relief device, is applicable to the connection of pressing crack construction mesohigh manifold.
Background technology
The at present domestic high pressure pipe joint type of attachment for well fracturing construction is more, and the overwhelming majority is by the overpressure protection apparatus of pressure break pump truck and shaft collar control pressure release.There is following problem in this pressure release mode:
1, when in work progress; once superpressure; can only pressure break pump truck be quit work by the overpressure protection apparatus of pressure break pump truck; but because the overpressure protector of pressure break pump truck is inductance type, if there is extremely, pressure break pump truck is cannot be out-of-work immediately so; will bring so great potential safety hazard; exceed the limiting value of high pressure pipe joint if pressure rises always, high pressure pipe joint will break, and injures people and equipment around.
2, after Oil/gas Well construction superpressure; the pressure moment of high pressure pipe joint is greater than its rated value, and (gas well overpressure protection value is 70.0MPa; oil well overpressure protection value is 45.0MPa); under this situation; relief valve pressure release by shaft collar or pressure break pump truck all exists larger potential safety hazard; and like this high pressure, shaft collar or relief valve are not easy to open, and open the sluices by force or relief valve also has certain damage to its internal construction.
Utility model content
In order to solve the potential safety hazard that in above-mentioned prior art, pressure release mode exists; and pressure release immediately, relief valve such as are difficult to open at the technical problem; the utility model aims to provide a kind of pressure relief device of high pressure pipe joint; without artificial pressure release, relief valve releasing pressure automatically, not only can protect high pressure pipe joint; and install convenient; easy and simple to handle, to invest littlely, service efficiency is high.
The utility model is achieved through the following technical solutions:
A kind of high pressure pipe joint pressure relief device, comprise the first T-shaped Highpressure Tee, cock and mechanical type relief valve, three ports of the first T-shaped Highpressure Tee are connected with the high pressure line of both sides and the input of described cock respectively, the output of cock is connected with the input of described mechanical type relief valve, and above-mentioned connection is oil and connects the ninth of the ten Heavenly Stems.
Further, the prefabricated pressure release scope of mechanical type relief valve is 0-105MPa.
Further, pressure relief device also comprises pressure sensor, and pressure sensor is connected between the first T-shaped Highpressure Tee and the input of cock by the second T-shaped Highpressure Tee, or between the output of cock and the input of mechanical type relief valve.Same, pressure sensor can also be connected between high pressure line and the first T-shaped Highpressure Tee by the second T-shaped Highpressure Tee, or is connected between high pressure line.Or pressure sensor is directly connected in the cecum of mechanical type relief valve.
Further, the input of the input of cock, pressure sensor and mechanical type relief valve is 2 inches.
The utility model not only can be protected high pressure pipe joint, mechanical type relief valve is opened automatically and carried out pressure release; Can monitor in real time the pressure of whole high pressure line, be convenient to tackle in time emergency case simultaneously.And it is convenient to install, easy and simple to handle, only need used unit to connect successively, to invest littlely, service efficiency is high.

Wherein: 1: high pressure line; 2: liquid flow direction; 3: the first T-shaped Highpressure Tees; 4: the second T-shaped Highpressure Tees; 5: pressure sensor; 6: cock; 7: mechanical type relief valve; 8: rocking handle.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Embodiment 1
As shown in Figure 1, an embodiment of the present utility model comprises the first T-shaped Highpressure Tee 3, cock 6 and mechanical type relief valve 7, three ports of the first T-shaped Highpressure Tee 3 are connected with the input of described cock 6 with the high pressure line 1 of both sides respectively, the output of cock 6 is connected with the input of described mechanical type relief valve 7, and the other two ends of mechanical type relief valve 7 are respectively cecum and the pressure relief opening of sealing.Connection between above-mentioned parts is oil and connects the ninth of the ten Heavenly Stems, can ensure good sealing and stability, and convenient connection and dismounting.
Rotate the rocking handle 8 of cock 6, make cock 6 in opening, set the overpressure protection value of mechanical type relief valve 7.The pressure release scope of mechanical type relief valve 7 is 0-105MPa, and the overpressure protection value of gas well is 70.0MPa conventionally, and the overpressure protection value of oil well is 45.0MPa.Mechanical type relief valve 7 can be identified force value automatically, because mechanical type relief valve 7 itself has a pressure knob, realizes the setting of force value by the demarcation of professional instrument.In the time that high pressure pipe joint internal pressure reaches rated value, the pressure release sector-meeting in mechanical type relief valve 7 is opened automatically, by the pressure relief opening of relief valve upper end, pressure is laid down.In the time of Pressure Drop to 0, the pressure release sector-meeting in mechanical type relief valve 7 automatically resets.Once cock 6 can ensure mechanical type relief valve 7 out of control or lost efficacy, can by this cock 6 is closed to guarantee continue construction.
Embodiment 2
In this embodiment, pressure relief device also comprises pressure sensor 5, and as shown in Figure 2, pressure sensor 5 is connected between the first T-shaped Highpressure Tee 3 and the input of cock 6 by the second T-shaped Highpressure Tee 4.
Embodiment 3
As shown in Figure 3, pressure sensor 5 can also be connected between the output of cock 6 and the input of mechanical type relief valve 7 by the second T-shaped Highpressure Tee 4.Certainly, pressure sensor can also be directly connected in the cecum of mechanical type relief valve.
Embodiment 4
As shown in Figure 4, pressure sensor 5 can also be connected between high pressure line 1 and the first T-shaped Highpressure Tee 3 by the second T-shaped Highpressure Tee 4, or is connected between high pressure line 1.
A pressure sensor 5 is only installed on whole high pressure line 1 and pressure relief device, and it,, for monitoring the integral pressure of construction mesohigh pipeline 1, is convenient to tackle in time emergency case, and position can freely be selected.
In the above-described embodiments, the input of the input of cock 6, pressure sensor 5 and mechanical type relief valve 7 is 2 inches.At present, the size of oil gas field high pressure line 1 is generally 2 inches, 3 inches and 4 inches.The no matter straight pipe-line of any size, one end that its threeway is positioned at axis is all necessary for 2 inches.Therefore, with the size of pressure sensor 5 and supporting first, second the T-shaped Highpressure Tee 3,4 of cock 6 can be according to the size of high pressure line 1 corresponding employing 2*2*2 respectively, 3*3*2,4*4*2, other pipe valve size constancies, to ensure the stable connection between each parts.
In the time of high pressure pipe joint internal pressure overrate, the utility model can be protected high pressure pipe joint, mechanical type relief valve 7 is opened automatically and carried out pressure release.Meanwhile, the utility model coordinates jointly with the overpressure protection apparatus of installing on pressure break pump truck, loses efficacy once pressure break pump truck overpressure protection apparatus, and high pressure pipe joint safe pressure relief device just plays an important role, and this has played the effect of double insurance to high pressure pipe joint.In addition, it is convenient, easy and simple to handle that the utility model is installed, without manually carrying out pressure release; And invest littlely, service efficiency is high, can monitor in real time the pressure of whole high pressure line 1, is convenient to tackle in time emergency case.
