Description
Technical field
The utility model relates to sample defroster, the antifreeze of sampling is taken specifically outside a kind of winter extremely frigid zones room
Sample valve.
Background technique
Currently, the development of oil extraction in oil field technology is gradually mature, oil field wastewater treatment also becomes oil field Green Development
Important component, at the same time, in face of the processing of oil field waste, sample detection is most important, and sampler is indispensable
Sampling equipment.
What present sample generally faced is lake, well, screw bolt well, electric immersible pump well, flowing well, water injection well etc., sampling
Valve plays a crucial role in sampling process, and with the growth of production time, winter severe cold areas can be quickly completed
Sampling is a relatively difficult thing, since the decline of environment temperature can make sampling that can not be normally carried out, sampling valve is caused easily to be frozen
It is stifled；Can not be sampled to solve the easy frozen block of common sampling valve outside winter room, the product that cannot will be sampled smoothly be sent to sensing chamber into
Row detection, it may appear that field data lag is made troubles for daily production run, so that economic benefit declines.
For another aspect, sampling will cause sample solidification not in time, so that ingredient changes in sample, inspector is real
Testing data can not be close to true value, cannot be accurate to sample evaluation, influences production requirement.This is that field sampling personnel can not evade
Responsibility, and threaten one of the work checked on of produced on-site quality.
The utility model patent of Patent No. 2017210565784 discloses a kind of antifreeze, anti-pollution sampler, including valve
Body, the valve inner are equipped with valve rod, and described valve rod one end is connect with sampling probe, the end of the valve rod and the fixed company of handle
It connects, the valve body tail portion is fixedly connected with sample inlet, and the valve body tail portion has been provided with several holes, the sample inlet two
End is equipped with flange, and the side of valve body is equipped with probe tube, and the valve body is fixedly connected with probe tube.It has the following deficiencies:
1, wherein valve rod and sampling probe are to separately design, and are connected by shop bolt, and part dispersion, junction is easy to produce
Raw loss；
2, valve body tail portion does not design filtering hole, and sampling hole is easy blocking；
3, valve body tail portion and sampling line are fixed, and leakage will be caused not control effectively when sample cock failure.
Summary of the invention
The purpose of this utility model is to provide a kind of antifreezing sampling valve, which is easily installed and tears open
Unload, valve close late gate in liquid level automatic-discharging, resistance to frost is reliable, solve the easy frozen block of common sampling valve outside winter room,
The problem of can not sampling.
The utility model antifreezing sampling valve, including valve body 3,3 one end of valve body are threadedly coupled with the valve rod 4 with handwheel 6, valve
3 other end of body is threadedly coupled with valve stem sleeve 2, and 2 end of valve stem sleeve is provided with filter cap 1, then on valve body 3 and sampling line 7
Valve 8 is pre-installed to be threadedly coupled.
When handwheel 6 screws, the circular conical surface of 4 end of valve rod and the seamless cooperation of circular conical surface of 2 end of valve stem sleeve.
3 lower part of valve body is provided with sampling mouth 9.
Valve body 3 and 4 threaded connection place of valve rod are additionally provided with gland 5.
The working principle of the utility model are as follows: the spool (valve rod 4 and valve stem sleeve 2) of antifreezing sampling valve is inserted into tested pipeline
In, spool (valve rod 4 and valve stem sleeve 2) opening and closing position is kept the temperature using the temperature of flow media in pipe, internal liquid temperature
Degree is more than freezing point, to realize that spool (valve rod 4 and valve stem sleeve 2) is sampled product and is effectively kept the temperature；When valve opening,
Cooperated by the circular conical surface of valve stem end and the circular conical surface of valve stem sleeve end, realizes reliable sealing；It is interior when valve is closed
Portion has good freeze-proof always in place's emptying state.
The utility model has the beneficial effects that:
1, in terms of existing technologies, the utility model is an integral structure, and small volume and less weight is easy to install and remove,
Valve closes liquid level automatic-discharging in late gate, and resistance to frost is reliable；
2, it is equipped with detachable filter cap, can prevent or reduce sampling probe hole plug probability, it is easy to maintenance；
3, valve body is reserved valve screw-internal thread fit by valve body external screw thread and sampling line and is fixed, once antifreezing sampling valve event
When barrier can not close, disassembly antifreezing sampling valve can be passed through and carry out leakage control and dimension by way of closing the reserved valve of sampling line
Repair replacement.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
In figure, 1 is filter cap, and 2 be valve stem sleeve, and 3 be valve body, and 4 be valve rod, and 5 be gland, and 6 be handwheel, and 7 be sampling line,
8 be prepackage valve, and 9 be sampling mouth.
Specific embodiment
With reference to the accompanying drawing, the utility model is described further.As shown in Figure 1, a kind of antifreezing sampling valve, including valve
Body 3,3 one end of valve body are threadedly coupled with the valve rod 4 with handwheel 6, and 3 other end of valve body is threadedly coupled with valve stem sleeve 2, valve stem sleeve 2
End is provided with filter cap 1, and then valve body 3 is threadedly coupled with the prepackage valve 8 on sampling line 7.
When handwheel 6 screws, the circular conical surface of 4 end of valve rod and the seamless cooperation of circular conical surface of 2 end of valve stem sleeve.
3 lower part of valve body is provided with sampling mouth 9.
Valve body 3 and 4 threaded connection place of valve rod are additionally provided with gland 5.
Assembling process: by the insertion valve body 3 of valve rod 4 and with being threaded into, suitably upper gland 5 simultaneously tightens handwheel 6, by valve rod
Set 2 is threaded into valve body 3, and filter cap 1 is tightened on 2 screw thread of valve stem sleeve by screw thread, the antifreezing sampling valve that assembly is finished
8 position of prepackage valve of sampling line 7 is installed on by 3 screw thread of valve body.
The utility model is realized in this way: when sampling, handwheel 6 is rotated counterclockwise, at this time drive of the valve rod 4 in handwheel 6
Lower back rotation retreats, and 4 circular conical surface of valve rod is separated with 2 circular conical surface of valve stem sleeve, and valve is in the open state at this time；Medium passed through
The hole of filter cap 1 flows out antifreezing sampling valve into the annular space of valve rod 4 and valve stem sleeve 2 through over sampling mouth 9；
After sampling, handwheel 6 is screwed clockwise, and valve rod 4 advances at this time, and circular conical surface is closely matched with 2 circular conical surface of valve pocket
It closes, valve is in close state at this time；Residual medium will continue to flow out by sampling mouth 9 in valve, at antifreezing sampling valve inside
In emptying state；Since the medium in measured tube wraps up spool (valve rod 4 and valve stem sleeve 2) always, therefore the valve is with good
Good resistance to frost.
