As shown in fig. 1, the utility model discloses a well head bits device, its structure includes bits manifold 100 of catching, and wherein bits manifold 100 of catching is provided with entry 101, entry 101 is connected and is provided with first manual wafer valve 102, first manual wafer valve 102 is connected with through the right angle bi-pass and is strained a section of thick bamboo 103, it is connected with second manual wafer valve 104 through the right angle bi-pass to strain a section of thick bamboo 103 free end, second manual wafer valve 104 free end connection is provided with export 105.

The utility model discloses a bits device is caught to well head is applicable to the well head position department of oil recovery operation in-process, can be accompanied with solid phase material usually when pit shaft output oil gas flows, mainly comes from the leaking stoppage material of using when leaking well if boring, the bridge plug piece etc. of returning out when boring the bridge plug, consequently sets up this bits device of catching in well head department. The oil and gas produced in the wellbore enters the debris trap 100 through an inlet 101 provided in the debris trap 100 and then enters a filter cartridge 103 connected to the first manual plate valve 102 by opening the valve by the first manual plate valve 102. When oil and gas flow flows through the filter cartridge 103, solid-phase substances such as rock debris or iron chips carried in the oil and gas flow are intercepted inside the filter cartridge 103, and the separation of the solid-phase substances from the fluid is realized in the filter cartridge 103. The fluid separated from the solid phase material passes through a second manual plate valve 104 connected to the other end of the filter cartridge 103 and flows to an outlet 105. Through the chip catching unit consisting of the first manual flat valve 102, the filter cartridge 103 and the second manual flat valve 104, the separation of the fluid and the solid-phase substances in the oil-gas flow produced from the well bore is realized, and the solid-phase substances are prevented from entering the downstream equipment or pipeline.

Because the inner diameter of the fluid input end of the oil outlet duct 201 is smaller than that of the fluid output end of the oil outlet duct 201, when the fluid medium flows through the oil outlet duct 201, the inner diameter of the cross section of the flowing oil outlet duct 201 is continuously increased, so that the flowing speed of the fluid medium is reduced, the impact of the output fluid medium on other pipelines connected to the oil outlet duct 201 is reduced, the downstream pipelines are protected, and the service life of the downstream pipelines is prolonged.

Preferably, the end of the valve core 202 of the throttle valve 200 is chamfered. The throttle valve 200 is a valve part that performs the basic function of flow control by means of the movement of the spool 202. Chamfering refers to machining the corners of a workpiece into a certain inclined plane. The end part of the valve core 202 is chamfered, so that the installation direction of the valve core 202 is defined, and the valve core 202 has the function of installation guide, so that the installation operation of the valve core 202 is more convenient, and the installation efficiency of the chip catching device is further improved.

Further preferably, a lifting frame 300 is arranged at the scrap catching manifold 100. The chip catching device is used for the position of a wellhead in oil extraction operation, but the wellheads arranged in different oil extraction operations are different, so that the chip catching manifold 100 in the chip catching device is provided with the lifting frame 300, the chip catching device can adapt to different wellhead heights in different oil extraction environments in the oil extraction operation, and the practicability of the chip catching device is improved.
