Abstract

The utility model relates to a built-in anti-freezing anti-theft sampling device and belongs to a sampling device for oil-field production wellheads and outdoor pipelines. A valve body is fixedly connected with a pipe body, a valve rod is in threaded connection with one end of the valve body, an O-shaped sealing ring is arranged between the valve rod and the valve body, a standby cap is in threaded connection with the other end of the valve body, a valve base is arranged on the standby cap and fixedly connected with the valve body, another O-shaped sealing ring is arranged between the valve rod and the valve base, and eight small holes are uniformly distributed on the valve body. The utility model has the advantages as follows: the built-in anti-freezing anti-theft sampling device adopts a built-in valve, has a novel structure, is convenient for installation, use and maintenance, has long service life, can sample and suppress the pressure at the oil-field production wellhead, and has both the anti-freezing and the anti-theft functions.

Description

Built-in freezing-proof theft-proof sampler
Technical field
The utility model belongs to oil well mouth and outdoor pipeline sampler.
Background technology
At present, the oil field shaft mouth sampler mostly is at the valve of the outside 12.7mm of connection of pipeline and takes a sample, pressure, operation such as build the pressure, do not possess the freezing-proof theft-proof function, oil well sampling in winter exists well head or outdoor pipeline sample cock to freeze and the interior crude oil of valve coagulates extremely, sampler does not have anti-theft feature, cause operating difficulties pipe and road to carry goods and materials to lose problem thus.
Summary of the invention
The utility model provides a kind of built-in freezing-proof theft-proof sampler, to solve the problem that present external sampler does not possess freezing-proof theft-proof function, inconvenient operation.
The technical scheme that the utility model is taked is: valve body is fixedlyed connected with body, valve rod is connected with the threaded one end of valve body, " O " RunddichtringO is installed between valve rod and valve body, being equipped with cap is threaded with the other end of valve body, valve seat is installed in and is equipped with on the cap, fixedly connected with valve body, " O " RunddichtringO is installed between valve rod and valve seat, be evenly equipped with 8 apertures on the valve body.The utility model advantage is novel structure, and working service is convenient, and valve is built-in, possesses antifreeze function; Long service life, special tool is opened, and certain anti-theft feature is arranged.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
The specific embodiment: valve body 2 is fixedlyed connected with body 1, valve rod 3 is connected with the threaded one end of valve body 2, " O " RunddichtringO 4 is installed between valve rod 3 and valve body 2, being equipped with cap 6 is threaded with the other end of valve body 2, valve seat 5 is installed in and is equipped with on the cap 6, fixedly connected with valve body 2, " O " RunddichtringO is installed between valve rod 3 and valve seat 5, be evenly equipped with 8 apertures on the valve body 2.
Working method of the present utility model is: body is directly connected on the pipeline, and valve body is built in the body, does not influence the pipeline liquid circulation, by decenter clutch valve rod is screwed out, valve rod separates with ball seat, and liquid enters valve seat from eight apertures in the pipeline, goes out from an effluent of helmet, finish sampling, because of sample valve is built in the pipeline, be incubated by working fluid in the pipeline, so antifreeze, open with special tool, have certain anti-theft feature.
