A kind of Novel oil well well mouth sampling valve

Technical field

It the utility model relates to a kind of Novel oil well well mouth sampling valve, is specifically related to a kind of swift to operate, simple, has Effect shortened in the well mouth of oil well of oil-gas accumulation or general mechanism operating time, the sampler for preventing non-working person's operation.

Background technique

Well head sample cock is a kind of guarantees in oil well production process to the one of producing well extraction liquid acquisition Kind wellhead assembly, it connect with production tree sample tap, plays the purpose of production wellhead Produced Liquid acquisition.In process of production, it adopts Liquid includes oil, gas and water and a small amount of H out₂S, CO etc. is toxic, pernicious gas；Production scene well mouth of oil well sample cock is using rotation Plug shut-off valve, open and close valve duration during oil well sampling, operator and extraction media contact time are long；Because taking out In field, the frequent maloperation of non-working person leads to oil pumping machine well head oil, gas leakage generation environment for oil machine, production tree running environment Pollution and petroleum resources waste.

Summary of the invention

The purpose of this utility model seeks to eliminate above-mentioned the deficiencies in the prior art and disadvantage, provide a kind of structure it is simple, Maintenance is quick, reaches the instantaneous open and close of valve using specific purpose tool, shortens operator in the operating time of oil-gas accumulation point, non- Staff can not carry out open and close operation to well mouth of oil well Sampler valves in the case where no specific purpose tool.

To reach above-mentioned technical effect, the utility model adopts the following technical solutions: a kind of Novel oil well wellhead sampling Valve includes: valve body, valve core, O-ring seal, clamping platen and special spanner；Valve body is that reducing tee includes that liquid feeding end (connects Connect end) and lower part outlet end, spool baffle, valve chamber；Valve core is that cylindrical body includes spool and valve rod, is integrated in processing, Spool bottom and middle part are equipped with deflector hole, and valve stem top is tetragonal body, and marks open and close line, carry out 90 ° of rotations with special spanner Instantaneous open and close are carried out to valve；O-ring seal is rubber pad, the gap between sealed valve core and valve rod；It is opened at the top of clamping platen It is fluted, it can adjust sealing ring elasticity with special spanner；Special spanner is that cylindrical body includes spanner and the arm of force, and spanner bottom end is With four square sockets of valve rod square body compatibility, spanner top is equipped with tongue can be elastic with clamping platen groove compatibility adjustment sealing ring Degree, spanner middle part are provided with through-hole, can install the arm of force additional.

Preferably, the spool bottom is equipped with feed liquor deflector hole.

Preferably, it is equipped with liquid deflector hole in the middle part of the spool.

Preferably, the spool periphery contacts sealing with valve chamber inner wall.

Preferably, the valve core valve rod inside contracts in valve chamber, can only use special spanner open and close valve.

The beneficial effects of the utility model

The utility model is mainly made of valve body, valve core, sealing ring and clamping platen；Valve body bottom end and well mouth of oil well take Sample mouth connects (solderable), and the other end is packed into valve core, O-ring seal, clamping platen；Spool bottom end and middle part are equipped with water conservancy diversion Hole guarantees extraction medium outflow by this channel；Reach the instantaneous open and close of valve with 90 ° of rotation internal withdraw type valve rods of special spanner；Contracting Personnel have prevented the operation of non-working person, have improved safe system in the time of oil-gas accumulation place when short well mouth of oil well samples Number reduces oil, the pollution of gas leakage generation environment and petroleum resources waste.

Detailed description of the invention

Fig. 1 is the utility model well mouth of oil well sample cock structural schematic diagram；

Fig. 2 is the utility model well mouth of oil well sample cock section view assembly structure diagram；

Wherein: 1- valve body, 2- valve core, 3- sealing ring, 4- clamping platen, 5- special spanner.

Specific embodiment

As shown in Figure 1 to Figure 2, a kind of Novel oil well well mouth sampling valve, including valve body 1, valve core 2, O-ring seal 3, Clamping platen 4 and attached special spanner 5.Valve body 1 includes connecting pin, spool baffle 7 and valve chamber；Valve core 2 is mounted in valve chamber It is made of spool and valve rod, spool, valve rod are cylindrical body, and it is four directions at the top of valve rod 9 that spool bottom and middle part, which are equipped with deflector hole 8, Body, and make have open and close line；O-ring seal 3 is greater than spool, the rubber washer less than valve rod, sealing valve core and valve to be multiple Bar；4 top surface of clamping platen is equipped with "-" type groove；5 bottom of special spanner is internal square hole and valve rod compatible use, top one It is elastic that font tongue adjusts sealing ring with clamping platen groove compatibility, and the arm of force can be installed additional by being provided with through-hole in the middle part of spanner, makes valve Open and close are convenient quick.

More preferably, after valve core is packed into valve chamber, valve rod is inside contracted in valve chamber, and the non-operator of no specific purpose tool can not be to new Type sample cock carries out open and close operation.

The utility model is mainly made of valve body, valve core, sealing ring and clamping platen；Valve body bottom end and well mouth of oil well take Sample mouth connects (solderable), and the other end is packed into valve core, O-ring seal, clamping platen；Spool is provided with deflector hole, spool baffle Spool is fixed in valve chamber with clamping platen, it is ensured that spool deflector hole and feed liquor, fluid hole pass through this to just when valve opening Channel guarantees extraction medium outflow；Reach the instantaneous open and close of valve with 90 ° of rotation internal withdraw type valve rods of special spanner；Shorten sampling Time has prevented the operation of non-working person, has improved safety coefficient, reduces oil, the pollution of gas leakage generation environment and oil gas The wasting of resources.

Above-described is only the preferred embodiment of the utility model.It should be understood that coming for those of ordinary skill in the art It says, under technical inspiration provided by the utility model, as the common knowledge of this field, other equivalent modifications can also be made And improvement, it also should be regarded as the protection scope of the utility model.
