Problems solved by technology
The existing constant pressure release valve has no adjustment function and cannot meet the pressure requirements of different pipelines, which is extremely inconvenient to use
Moreover, the size of its air inlet is different from the standard interface of the oil pipeline. When connecting, it is necessary to use a connector to connect the two. This connection creates two connection points, and the risk of leakage is relatively large.
There is only one exhaust port of the constant pressure release valve, and the pressure of the discharged gas is generally relatively high, which is difficult to control

Embodiment Construction
[0008] The present invention will be further described below in conjunction with accompanying drawing:
[0009] In the figure, 1-valve body, 2-exhaust port, 3-adjusting rod, 4-valve seat, 5-spring, 6-valve ball, 7-air inlet, 8-adapter.
[0010] Such as figure 1 As shown, the two exhaust ports 2 are respectively located on both sides of the valve body 1, the adjusting rod 3 runs through the upper part of the valve body 1, and its lower end is connected with the upper end of the valve seat 4, and the lower end of the valve seat 4 is connected with the valve ball 6 through the spring 5, and the valve ball 6 is placed on the upper end of the air inlet 7, and the lower end of the air inlet 7 is located outside the valve body 1 and connected with the adapter 8.
[0011] The device is connected to the interface of the oil pipeline through the adapter 8. The casing gas enters the constant pressure release valve through the adapter 8, pushes the valve ball 6 away from the air inlet 7 ...

The invention provides an adjustable sleeve air release device, which comprises a constant-pressure air release valve. The adjustable sleeve air release device is characterized by also comprising an adaptor, wherein the constant-pressure air release valve comprises a valve body, air vent holes, an adjusting rod and the like; the adjusting rod penetrates through the upper part of the valve body; the lower end of the adjusting rod is connected with the upper end of a valve seat; the lower end of the valve seat is connected with a valve ball through a spring; the valve ball is placed at the upper end of an air inlet; and the lower end of the air inlet is positioned outside the valve body and connected with the adaptor. The adjustable sleeve air release device has the advantages that by adding the adjusting rod, the compression amount of the spring can be adjusted, and a pressure value of the device is adjusted, so the pressure value is equal to a constant-pressure value of a petroleum pipeline, the pressure application range of the device is expanded, the device can be applied to different pipelines, and using of the device is facilitated; by forming two air vent holes, air can be quickly and conveniently vented under small pressure; and by using the adaptor, connection of the device and the petroleum pipeline is facilitated, the number of connecting points is decreased, and the phenomenon of air leakage from a joint is effectively prevented.
Description
[0001] technical field [0002] The invention relates to the field of oil production equipment, in particular to a casing deflation device. Background technique [0003] The casing of the oil production pipeline is equipped with a constant pressure release valve to discharge the gas in the casing in time. The existing constant pressure release valve has no adjustment function and cannot meet the pressure requirements of different pipelines, so it is extremely inconvenient to use. Moreover, the size of its air inlet is different from that of the standard oil pipeline interface, and a connector is needed to connect the two when connecting. This connection produces two connection points, and the hidden danger of leakage is relatively large. There is only one exhaust port of the constant pressure release valve, and the pressure of the discharged gas is generally relatively high, which is difficult to control. Contents of the invention [0004] In order to solve the above tec...
