Description
Technical field：
The present invention relates to a kind of well samplers with antifreeze function, it belongs to the water sample intake dress of water injection well in oil fields
Put 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 put, 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 the present invention is to provide a kind of simple in structure, the well with antifreeze function freezed can be effectively prevent to take
Sampling device.
The object of the present invention is achieved like this：
A kind of well sampler with antifreeze function, it includes a horizontal and is arranged on taking on horizontal
Sample valve；It is characterized in that the corresponding mounting hole of above and below a pair is provided on the stage casing tube wall of the horizontal, in institute
A sample cock is vertically arranged 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 hangs down for one with one
The frustum cone structure of straight water outlet；The spool is more than the member structure of lower pole segments for upper diameter, and the top is straight greatly
A transition round platform is connected between diameter rod piece and lower small diameter rod piece.
Structure is threaded 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 configuration of the present invention is simple, it is convenient to open and close, using the valve seat with inlet opening, as long as realizing in tube body has
Flow is out-of-date, among the liquid of valve seat and spool always in flowing, plays effective antifreeze effect.
Description of the drawings：
Fig. 1 is the structural diagram of the present invention
Specific embodiment：
With reference to Fig. 1, the present invention is further detailed：
As shown in fig. 1, in the present embodiment, the present invention includes a horizontal 1 and is arranged on taking on horizontal
Sample valve；Same as the prior art, sample cock is arranged in a mutually vertical manner with horizontal.
In order to achieve the object of the present invention, sample cock of the invention has carried out the improvement in structure.In the level
Corresponding mounting hole above and below a pair is provided on the stage casing tube wall of tube body, i.e., selection is right up and down at the intermediate position of horizontal 1
A hole is respectively outputed in the position of title, is the mounting hole of sample cock, is vertically set in the mounting hole of the two upper and lower correspondings
Put a sample cock.
The spool 3 that the sample cock includes the valve seat 2 of tubular structure and 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 to be threaded structure in the outside of the bonnet 4, 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 mode installation is simple, is connected firmly, it may have good
Good sealing effect.
In order to realize that the present invention ensures that spool and valve seat may be in the liquid of flowing, the purpose to freeze is prevented, it is described
Valve seat 2 lower part tube wall on symmetrical a pair of of the inlet opening 21 in installation position, when having flow in horizontal 1 in this way, flowing water
Water inlet will be entered in valve seat by this, and keep with the flowing of water in horizontal and always in horizontal and
It is flowed between valve seat.The flowing of such ceaselessly liquid will effectively prevent from freezing.
The frustum cone structure 23 that the lower part tail end of the valve seat 2 carries a water-exit vertically mouth 24 for one, the spool 3 are
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 present invention, the engaging portion of the spool and bonnet is provided with sealing ring
5。
The operation principle of the present invention：
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 present invention is at closed state.
When rotary spool 3 counterclockwise, the transition round platform 31 of spool 3 is departing from the water-exit vertically mouth 24 of 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 present invention is in opening, Ke Yiqu
Sample.
The present invention can utilize flanged joint on the pipeline for needing to absorb water sample.
