Specific embodiment
It is new to this practicality below in conjunction with accompanying drawing to make the purpose of this utility model, technical scheme and advantage clearer
The implementation method of type is described in further detail.
The utility model embodiment provides a kind of sampling valve, and referring specifically to Fig. 1, Fig. 2, the sampling valve includes：It is connected to
Sampling valve body 2 on the side wall of oil pipe 1, and the valve rod assembly being detachably connected with sampling valve body 2；In sampling valve body 2
It is provided with the fluid passage parallel to horizontal plane, the inside of fluid passage connection oil pipe 1 and the outside of sampling valve body 2；Valve rod
Component includes the shaft-like stem body 3 that can enter inside sampling valve body 2, and the end of stem body 3 can block the fluid
Connection outside passage, the inside of blocking oil pipe 1 and sampling valve body 2.
The operation principle of the sampling valve that the utility model embodiment is provided is：Sampling valve body 2 is fixedly connected on oil
On the side wall of pipe 1, connected outside the inside of oil pipe 1 and sampling valve body 2 by sampling the fluid passage in valve body 2 parallel to horizontal plane
Portion, further sets dismountable valve rod assembly, and fluid passage is blocked or opened by stem body 3.When being sampled, lead to
Cross the connection of stem body 3 fluid passage so that the production fluid outflow in oil pipe 1, complete sampling.
And it is preferred that sampling valve body 2 is connected with the middle part of oil pipe 1, and ensure fluid passage and water in the sampling valve when installing
Plane is parallel, and in the absence of volume compared with large cavity in so sampling valve body 2 after the completion of sampling, and fluid passage is horizontally disposed not
Easily accumulate dead oil, thus when next sampling operation is carried out without setting-out, it is to avoid the crude oil that setting-out is caused is wasted, the person of reducing
The workload of work.
Further, the sampling valve that the utility model embodiment is provided also assures that its oil sample for being taken has and represent
Property.Specifically, because the oil sample moisture content on the top of oil pipe 1 is relatively low, the oil sample moisture content of the bottom of oil pipe 1 is higher, and the middle part of oil pipe 1
Oil sample moisture content can strictly according to the facts reflect the overall moisture content of oil well, therefore be preferred with the middle part oil sample of oil pipe 1 during sampling.So can
To understand, preferably sampling valve body 2 is connected to ensure to draw oil sample with the middle part of oil pipe 1 and comes from the middle part of oil pipe 1.Further
Ground, the fluid passage in sampling valve body 2 is set parallel to horizontal plane, with the carrying out of sampling, the liquid fluid pressure in oil pipe 1
When being declined slightly, because fluid passage is horizontally disposed so that the oil pipe the superiors and undermost oil sample are difficult outflow, same to ensure
Draw oil sample representative.
To sum up due to improving the structure of sampling valve, the dead oil of sampling valve remaining after the completion of sampling is effectively reduced, under
Avoid being vented the waste that crude oil is caused during secondary operation, while reducing the workload of employee.
