Abstract
The utility model provides an anti-clogging emptying device and belongs to a production device for oil extraction in oilfields. The anti-clogging emptying device is provided with a joint, wherein one end of the joint is assembled with one end of a casing through threads, the other end of the casing is assembled with an emptying jack screw through threads, a baffle ring is assembled in the casing, springs are arranged outside the baffle ring, a steel ball is arranged outside the springs, flanges are arranged in the casing outside the steel ball, and an emptying hole is formed at the inner end of the emptying jack screw. The anti-clogging emptying device has the advantages of reasonable structure, convenience and reliability in use, low possibility of clogging, thoroughness in emptying and high use safety.
Description
Technical field
The utility model provides the oil recovery of a kind of oil field to produce and has used device, especially a kind of emptying device.
Background technology
In daily oil, water well test work progress, need the use test blowout hookup.Atmospheric valve on this device adopts the needle valve of 4 " or 6 ", portalling of valve is less, when the emptying of test blowout hookup, problems such as existence is easily stopped up, emptying is not thorough, when particularly winter, heavy oil wells or water injection well were constructed, this phenomenon is particularly outstanding, and emptying does not thoroughly cause blast on fire easily, and constructing operation personnel's safety has been caused great threat.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of anti-clogging emptying device, to improve the safety of emptying.
The utility model is to realize like this, the anti-clogging emptying device, it has joint, joint one side is installed together by an end of screw thread and housing, and the other end of housing is installed together by screw thread and emptying jackscrew, and baffle ring is installed in the housing, there is spring in the baffle ring outside, there is steel ball in the spring outside, in the housing in the steel ball outside flange is arranged, and there is relieving device emptying jackscrew the inner.
Adopt the anti-clogging emptying device of said structure, rational in infrastructure, easy to use and reliable, be difficult for stopping up, emptying is thorough, use safe.
Description of drawings
Fig. 1 is the schematic diagram of the utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing further specifies concrete structure of the present utility model.
As shown in drawings, the anti-clogging emptying device of the utility model, it has joint 11, joint one side is installed together by an end of screw thread and housing 10, and the other end of housing is installed together by screw thread and emptying jackscrew 8, and baffle ring 2 is installed in the housing, there is spring 3 in the baffle ring outside, there is steel ball 5 in the spring outside, in the housing in the steel ball outside flange 9 is arranged, and there is relieving device 6 emptying jackscrew the inner.
During use, the joint opposite side is welded on the lubricator 1 of well head, and the joint inner chamber communicates with the lubricator inner chamber.When needing emptying, by rotating the emptying jackscrew, make the emptying jackscrew inner face withstand on the steel ball, and the compressing steel ball overcomes the elastic force of spring and breaks away from flange in the housing, and relieving device, the emptying jackscrew inner chamber of oil gas on the space between joint inner chamber, shell inner cavity, steel ball and the outer casing inner wall, emptying jackscrew in the lubricator discharges.
The outer end of emptying jackscrew can be shape of threads, so that connect flexible pipe, oil gas is caused at a distance, further improves the convenience of using.
Also handle 7 can be arranged on the emptying jackscrew, to improve the convenience of its rotation.
The external surface of shell can be fluted 4, so that use spanner.
