Description

The two anti-sampling manographs of combined type

The utility model relates to a kind of oil field can be antifreeze to oil well, again sampling that can be antitheft, manograph.

The oil field needs oil well is carried out sample examination and shaft mouth test pressure on stream, the smooth degree of pressure test depends on the inner structure of pressure tester, but the degree of reliability of result of laboratory test not only depends on result of laboratory test, and is also relevant with sampler and sampling mode; The performance of sampler is bigger to the influence of result of laboratory test.At present, the sampling pressure measurement of oil field shaft mouth is discrete, and especially pressure measurement form is more, and is extremely lack of standardization.Be located in northern oil field, preventing freeze in winter is that this series products must be considered, most sampling pressure valves are because structure is not too reasonable, be added with the seepage phenomenon outward and produce and freeze, can not operate smoothly, promptly enable to take a sample and the pressure measurement operation, because remaining a large amount of cryogenic media in the valve, also the authenticity of influence sampling produces pressure drop to the pressure measurement operation, has a strong impact on the accuracy of pressure measurement numerical value.Some is located in the oil well at edge, oil field, and the lawless person utilizes sampling, pressure valve stolen, and existing product does not have anti-theft feature, and also lacks the simplicity of installing.

In view of this, sampling and pressure measurement are united two into one, other should be taken into account that the antifreeze and oil field in winter generally is distributed in the wild country, wilderness, also should have anti-theft feature, and simple in structure, therefore can't increase on the cost under many situations, just can bring the increase of function greatly easy to use, the work efficiency that increases substantially, this novel wound motivation place of grinding just.

The utility model designer, does a brand-new design and constitutes on the basis of feasibility study repeatedly by means of being engaged in the practical experience that all kinds of instrument and equipments are researched and produced processing and other fields for many years, gets this novel generation eventually.

At the deficiencies in the prior art, this novel purpose is that design is a kind of existing antifreeze, has antitheftly again, can also get rid of the two anti-samplings of combined type, the manograph of remaining medium in the body simultaneously, helps taking a sample, the authenticity of pressure measurement.

The purpose of this utility model can reach by the following technical programs, and the utility model constitutes the sampler part by sampling valve seat, sampling valve casing, sampling spool, sampling valve rod and sampling valve gap; Pressure measurement valve seat, pressure measurement valve body, unlatching core, pressure measurement spool and back-moving spring and back-moving spring envelope piece constitute the manograph part; The sampling valve seat stretches in the sampling pressure measurement housing and is welded on the wall, tubular shell stretches into the valve seat thread connection and adds pivot pin and fixes, in the sampling valve casing toroidal inner chamber is arranged, the frustum formula spool that is mated, on the sampling valve rod threaded body is arranged, and bar is terminal for the rib body is hidden in the valve gap, has pivot pin to fix on sampling valve casing and the sampling valve gap joint portion, on the sampling valve casing sample tap is arranged; The pressure measurement valve seat is welded on the pressure measurement conduit, and the pressure measurement valve body stretches into the valve seat thread connection and adds pin and fixes, and the first half of pressure measurement valve body has the connecting port of pressure gauge, middle part that the core passage of unlatching and seal are arranged, and Lower Half is provided with measuring pressure passage and back-moving spring.Above-mentioned sampling valve seat is a tubular structure; Above-mentioned pressure measurement valve seat is a tubular structure.

The utility model integral body is connected by solid drawn tube, simple installation, have compared to existing technology: because valve casing (stopple coupon or measuring pressure passage) stretches into sampling pipe, not only help antifreeze, and when sampling, do not influence flow state, make taken a sample oily representative, sampling, the unlatching part of manograph is hidden in the valve, do not have specific purpose tool and pressure measurement gauge stand can not open valve operation, help antitheft, for sampling part, in case occur freezing, can get rid of by spiral valve rod, the authenticity that helps taking a sample is for the pressure measurement part, cooperate with the fluid passage of pressure gauge owing to open the core aperture, avoided the frozen problem that leaks of crude oil.

Further illustrate the utility model below in conjunction with accompanying drawing,

Fig. 1 is the utility model structure cut-open view.

Of the present utility modelly be composited by housing 1, sampling part is by sampling valve seat 8, sampling valve casing 5, sampling valve rod 4 and sampling valve gap 3 constitute, and the pressure measurement part is by pressure measurement valve seat 9, pressure measurement valve body 10, open core 11, pressure measurement spool 13, back-moving spring 14 and back-moving spring envelope piece 15 constitute; To sampling part, the application adopts the sampling valve seat 8 of tubular structure, and sampling valve casing 5 stretches in the housing 1, can stretch into 1/2nd housing pipe diameters, is welded on the pipe body then; Sampling valve casing 5 stretches into sampling valve seat 8 and is threaded and adds stationary shaft pin 7; In the sampling valve casing 5 toroidal inner chamber 20 is arranged, the frustum formula spool of the sampling valve rod 4 that is mated, on the sampling valve rod threaded body is arranged, and bar is terminal for the rib body is hidden in 3 li of sampling valve gaps, has pivot pin 6 fixing on sampling valve casing and the sampling valve gap joint portion, and sampling mouth 2 has sample tap 28 down on the sampling valve casing, more than fixedly 6 of pivot pin 7 and pivot pins prevent pilferage, destruction, valve stem end is hidden in 3 li of sampling valve gaps, and non-specific purpose tool can not be opened sample valve, stops the stolen phenomenon and takes place; For this novel employing tubular type pressure measurement valve seat 9 of pressure measurement part, pressure measurement valve body 10, except that pressure gauge connection 22, all stretch into 1 li of housing, housing 1 is identical with the connected mode and the sampling part of pressure measurement valve seat 9, pressure measurement valve body 10 stretches into valve seat 9 thread connection and adds pin 12 fixing, valve casing 10 has open channel 21 and seal 26, what be mated is to open core 1 and 1 ball spool 13, open core 11 a little higher than pressure gauge connection baseplanes 23, because the existence of pin 12, prevented that manograph from being dismantled by malice, be hidden in 22 li of pressure gauge connections and open core 11, except that being screwed into tensimeter, can not open this core, if open with foreign matter, will block circular hole passage 24, this will prevent the generation of stealing.
