Description
Technical field：
The utility model is related to a kind of well sampler with antifreeze function, the water sample that it belongs to water injection well in oil fields is taken the photograph
Take device field.
Background technology：
Oil field water well sampling valve majority is production tree or the external common angle valve of pipeline at present.The well sampling dress of these types
It is all that independent part exists to set, and is typically mounted on the end of pipeline.And these devices are generally within outdoor, in the extremely frigid zones winter
Ji Rongyi is freezed, and loses sampled functions.
Invention content：
The purpose of this utility model is to provide a kind of simple in structure, the water with antifreeze function freezed can be effectively prevent
Well sampler.
What the purpose of this utility model was realized in：
A kind of well sampler with antifreeze function, it includes that a horizontal takes with what is be arranged on horizontal
Sample valve；It is characterized in that the corresponding mounting hole of a pair or more is provided on the stage casing tube wall of the horizontal, in institute
It is vertically arranged a sample cock in the upper and lower corresponding mounting hole stated；The sample cock includes the valve seat of a tubular structure
The spool being placed in one by one in valve seat is provided with one for connecting valve seat and valve between the valve seat and a spool
The bonnet of core；Inlet opening is provided on the lower part tube wall of the valve seat, the lower part tail end of the valve seat is one vertical with one
The frustum cone structure of straight water outlet；The spool is the member structure that upper diameter is more than lower pole segments, and the top is straight greatly
A transition round platform is connected between diameter rod piece and lower small diameter rod piece.
It is threaded structure in the outside of the bonnet, the inner surface on the top of the valve seat is provided with and bonnet
The helicitic texture of connection.
The engaging portion of the spool and bonnet is provided with sealing ring.
The utility model is simple in structure, and it is convenient to open and close, using the valve seat with inlet opening, as long as realizing tube body
In have that flow is out-of-date, valve seat and spool are among the liquid of flowing always, play effective antifreeze effect.
Description of the drawings：
Fig. 1 is the structural schematic diagram of the utility model
Specific implementation mode：
With reference to Fig. 1, the utility model is further detailed：
As shown in fig. 1, in the present embodiment, the utility model includes a horizontal 1 and is arranged on horizontal
Sample cock；Same as the prior art, sample cock is arranged in a mutually vertical manner with horizontal.
In order to realize that the purpose of this utility model, the sample cock of the utility model have carried out the improvement in structure.Institute
It is provided with the corresponding mounting hole of a pair or more on the stage casing tube wall for the horizontal stated, i.e., is selected at the intermediate position of horizontal 1
Position symmetrical above and below is selected, a hole is respectively outputed, is the mounting hole of sample cock, in the mounting hole of the two upper and lower correspondings
In be vertically arranged a sample cock.
The sample cock includes the valve seat 2 of a tubular structure and the spool 3 that is placed in one by one in valve seat.In order to
Valve seat 2 and spool 3 are linked together, a bonnet 4 is provided between the valve seat 2 and a spool 3.Constitute center
It is spool 3, periphery is valve seat 2, and middle layer is the valve of the three-decker of bonnet 4.In the present embodiment, using threaded connection
Mode connect spool and bonnet, that is, be that the outside in the bonnet 4 is threaded structure, in the upper of the valve seat 2
The inner surface in portion is provided with the helicitic texture being connect with bonnet 4.This connection type installation is simple, is connected firmly, it may have good
Good sealing effect.
In order to realize that the utility model ensures that spool and valve seat may be in the liquid of flowing, the purpose to freeze is prevented,
Symmetrical a pair of of the inlet opening 21 in installation position on the lower part tube wall of the valve seat 2, when having flow in horizontal 1 in this way,
Flowing water will enter in valve seat water inlet by this, and keep with the flowing of water in horizontal and always in horizontal tube
It is flowed between body and valve seat.The flowing of such ceaselessly liquid will effectively prevent from freezing.
The lower part tail end of the valve seat 2 is a frustum cone structure 23 for carrying a water-exit vertically mouth 24, and the spool 3 is
Upper diameter is more than the member structure of lower pole segments, is connected between the top major diameter rod piece and lower small diameter rod piece 32
There is a transition round platform 31.
In order to further ensure the sealing effect of the utility model, it is provided in the engaging portion of the spool and bonnet close
Seal 5.
The operation principle of the utility model：
When rotating clockwise spool 3, the edge of the water-exit vertically mouth 24 of 2 lower end of transition round platform 31 and valve seat of spool 3
Contact, has sealed water-exit vertically mouth, such the utility model is at closed state.
When rotary spool 3 counterclockwise, the water-exit vertically mouth 24 of the transition round platform 31 of spool 3 departing from 2 lower end of valve seat
Edge, then since the diameter of lower small diameter rod piece 32 is less than water-exit vertically mouth 24, then the utility model is in open state, can
With sampling.
The utility model can utilize flanged joint on the pipeline for needing to absorb water sample.
