It produces.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model.
Specific embodiment
To more fully understand the utility model, with reference to the accompanying drawings and examples to the utility model further description.
As shown in Figure 1, a kind of shale gas well plunger mining wellhead assembly, including lower part four-way, two sides and top it is logical
The first left manual flat valve 14 is respectively equipped on road, manual flat valve 1 on the first right manual flat valve 16 and first, left side it is logical
Casing pressure assembly 15 is installed on road, the channel on top is connected by crossover flange with main channel, and main channel is equipped with top four
Logical 4, the second left manual flat valve 5 is respectively equipped on the channel of four sides, manual platform on the second right manual flat valve 17, second
Valve 3 and the second lower manual flat valve 18, left channel are passed through on the right side of flanged joint by vertical tube on the left of flanged joint, right channel
Vertical tube, left and right side vertical tube are respectively equipped with left throttle valve 8, right throttle valve 19, and the top passageway of top four-way is returned by flanged joint
