The specific embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
A kind of anti-freeze pressure meter sample valve as shown in Figure 1 comprises pressure meter 1, pressure meter pipe nipple 2, valve body 4, handle 5 and receiving manifold 8; Described valve body 4 comprises sample valve cavity 6, and described sample valve cavity 6 lower ends are provided with that relief hole 7, left end inlet place are provided with male thread short circuit head 10, the middle part is provided with head towards the one way valve 11 of described male thread short circuit head 10; Described sample valve cavity 6 left end inlet places are connected with described receiving manifold 8; Between described sample valve cavity 6 left end inlet places and the described receiving manifold 8, by interior screw thread short circuit head 9 be connected male thread short circuit head 10 and connect; Described one way valve 11 afterbodys are connected with described handle 5, and described handle 5 is by the described one way valve 11 of spiral rotating opened/closed; Described sample valve cavity 6 upper ends are communicated with described pressure meter pipe nipple 2; Described pressure meter pipe nipple 2 is communicated with described pressure meter 1.
In a preferred embodiment, described sample valve cavity 6 upper ends and described pressure meter pipe nipple 2 connectivity parts are provided with plunger 3, and described plunger 3 slides with the tube wall sealing of described pressure meter pipe nipple 2.
In the embodiment that is more preferably, described relief hole 7 places are provided with the plug 12 of the described relief hole 7 of opened/closed.
With minimum 40 degrees below zeros that reaches of ground outdoor temperature in winter such as Inner Mongols, it is example that the anti-freeze pressure meter sample valve is installed, the anti-freeze pressure meter sample valve has been arranged, water the operation of valve has just all economized with hot water, as long as opening valve just can take a sample or enroll pressure, save employee's labour intensity and the security reliability on operation is used, solve no longer to water logical valve with hot water or suppress out valve by fluid pressure in the well when oil well wellhead sampling or admission pressure in the winter of cold unsafe accident occurs.
Screw thread short circuit head 9 is connected sample valve cavity 6 with male thread short circuit head 10 in adopting with flow string header 8, the distance that is connected of shortening sample valve cavity 6 and receiving manifold 8 pipelines.On the pipe nipple after sample cock is installed in interior screw thread short circuit head 9 and male thread short circuit head 10 is connected, shorten the anti-freeze pressure meter sample valve and are connected the connection distance of pipeline with receiving manifold, guarantee the effective communication of receiving manifold 8 interior crude oil temperature fields.An oil outlet is left in sample valve cavity 6 upper ends, at oil outlet the pressure meter pipe nipple 2 that an inwall cuts open light is installed.At plunger 3 of pressure meter pipe nipple 2 inner installations, can in pressure meter pipe nipple 2, move freely.Plunger 3 is filled anti-icing fluid in pressure meter pipe nipple 2 He in the pressure meter 1 when pressure meter pipe nipple 2 bottom.Utilize pressure meter pipe nipple 2 that pressure meter 1 and sample cock are coupled together.After opening sample valve, liquid enters the anti-freeze pressure meter sample valve by receiving manifold 8 in the well, and extruding plunger 3 moves extruding anti-icing fluid and makes pressure meter 1 show numerical value on the plunger 3.Rotary handle 5 control one way valves 11 are opened plug 12 releases after closing sample valve, make plunger 3 get back to original position, when plunger 3 recovers with the liquid in the sample valve cavity 6 by outside relief hole 7 discharge valves, prevented the phenomenon that sample valve is frozen in the winter time.Open and open again sample valve behind the plug 12 and just can take a sample or emptying receiving manifold 8, avoid freezing.
The present invention mainly is convenient in order to solve well mouth of oil well sampling in winter and to implement pressure.Its means have shortened the connection distance that the anti-freeze pressure meter sample valve is connected with receiving manifold, make the temperature field energy effective communication of receiving manifold 8 to sample valve cavity 6 places, have prevented the sample valve frozen block.Pressure meter pipe nipple 2 takes plunger type to promote the anti-icing fluid conducting pressure, has solved pressure meter frozen block problem.Greatly reduce the work difficulty of employee's sampling, pressure measurement, prevented from stinging the leakage generation of accident.
More than by the detailed description of concrete and preferred embodiment the utility model; but those skilled in the art should be understood that; the utility model is not limited to the above embodiment; all within spirit of the present utility model and principle; any modification of doing, be equal to replacement etc., all should be included within the protection domain of the present utility model.
