Embodiment Construction
[0022] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments and accompanying drawings are used for a detailed description, as follows:
[0023] The embodiment of the present invention provides a wellhead diversion sampling valve, such as Figure 1~7 As shown, the wellhead diversion sampling valve includes a valve body 1, a valve core 2, a clockwork 3, an end cover 4, a connecting piece 5, a sealing part and a transposition operating rod 6, and the bottom side of the valve body 1 has a vent opening 1-1. There is a sampling port 1-2 on the other side, a liquid inlet 1-3 in the center of the upper part of the valve body 1, and a first cavity 10 that runs through the valve body in one direction on one side of the valve body 1. , the spool 2 is inserted into the first cavity 10, the outer end surface of which is installed with the spring 3 and then fixed and sealed by the e...

The invention discloses a wellhead diverting sampling valve. The wellhead diverting sampling valve comprises a valve body, a valve element, a spring, an end cover, a connecting piece, a sealing component and a transposition operating rod; a first cavity which penetrates through the interior of the valve body in a one-way mode is formed in one side of the valve body; the valve element is inserted into the first cavity; a second cavity is formed in the valve element; first through openings are formed in the upper end face and the lower end face of the valve element correspondingly; a crude oil emptying passage is formed between the two oppositely-arranged first through openings and the second cavity; second through openings are formed in the front end face and the rear end face of the valveelement correspondingly; a crude oil sampling passage is formed between the two oppositely-arranged second through holes and the second cavity; the connecting piece is arranged above the valve body; ahollow flow channel is formed in the connecting piece; and the sealing component is arranged between the hollow flow channel and an oil passing pipeline. The wellhead diverting sampling valve is simple and practical in structure, loss-free sampling and emptying of crude oil can be achieved, the problem that no place is allowed for containing in conventional crude oil emptying sampling is solved,and potential safety and environmental protection hazards of sampling operation are greatly reduced.
Description
technical field [0001] The invention relates to the field of petroleum oil extraction accessories, in particular to a wellhead diversion sampling valve. Background technique [0002] At present, in oil fields with complex geographical environments and long fronts, daily wellhead sampling often has the problems of ineffective recovery of vented crude oil and difficulty in tertiary sampling operations. During the sampling process, the annual cumulative production loss is considerable, and the probability of pollution and sludge is relatively high. Through the analysis, it was found that the main reason for the loss of production during sampling was that the emptied crude oil was separated from the original normal production system and could not be recovered; the crude oil could not be recovered or the recovery cost was too high to increase the cost. Contents of the invention [0003] In view of this, the main purpose of the present invention is to provide a wellhead diversi...
