Description
Technical field
The present invention relates to the later high pressure sampler of a kind of transfer station transfer pump, specifically a kind of autocontrol high pressure crude oil sampling apparatus.
Background technology
Crude oil is defeated multi-purpose station outward, want external output oil sampling to carry out the crude oil property assay, especially outer output oil is moisture must to be controlled in the moisture finger, present sampling method all is to adopt the hand sampling method, the hand sampling method has following shortcoming: will bleed off the dead oil of stopple coupon and sample valve when 1, taking a sample, cause the crude oil loss.2, because line pressure is very high, one opens sample valve crude oil first in the mode of splash out, sprays to such an extent that be that crude oil causes environmental pollution everywhere.3, all more than 3.0Mpa, it is very difficult to open sample valve, and casualty accident easily occurs for sampling pressure.4, because the high sampling amount of pressure is difficult to control, sometimes get the requirement that just can reach several times taken amount, if the phenomenon that crude oil overflows the sample bucket often occurs bad the going back of sample valve control.
Summary of the invention
The purpose of this invention is to provide a kind of autocontrol high pressure crude oil sampling apparatus, overcome the defective that above-mentioned prior art exists, guarantee environmental protection, the safety of sampling and the sampling automatic control convenience of taking a sample.
Technical scheme of the present invention is achieved in the following ways:
The present invention includes electric actuator, self-actuated controller, weight sensor, sampling housing, gland, sample tap, sealing-plug and drive link, the housing that it is characterized in that taking a sample is made as cylindrical, center, the end is provided with oil supply hole, interior week is provided with box thread, be provided with a sample tap in the bottom of middle part periphery, box thread is provided with the sealing-plug of threaded engagement, the top is provided with the gland of flange connection or screwed connection, gland top is provided with the pressure cap that is threaded, and is provided with pressure pad and sealed packing between gland and pressure cap; Fix a columniform drive link at the sealing-plug center, drive link passes gland, and pressure pad is connected center pit and is connected with the copper sheathing of electric actuator with pressure cap; The copper sheathing junction of drive link and electric actuator is processed into square separately, is provided with the gap between the two, drive link
Freely stretch out in the post electric actuator copper sheathing; Be provided with a weight sensor in the bottom of sample tap, the control circuit of electric actuator is connected executive circuit and is connected with the control circuit of self-actuated controller with weight sensor.
Sealing-plug is made as cylindrical, and periphery is provided with male thread, and the bottom is fixed with conical oil resistant rubber sealing gasket.
Week be provided with bevel angle at the bottom of the sampling housing, the oil resistant rubber sealing gasket bottom sealing-plug is sealed and matched.
In the automatic control circuit of self-actuated controller to the weight sensor weight signal and sample time signal control circuit make AND circuit, weight signal is preferentially controlled.
Compared with the prior art the present invention has the following advantages:
1, can avoid discharging " dead oil " than the more environmental protection of existing sampler;
2, not strict to the pressure variation requirement of delivery line, both be adapted to low-pressure line, also be adapted to the high-pressure delivery pipeline;
3, working stability, reliable can reach the requirement of GB/T1884-1998;
4, adopted the weight sensor priority circuit, the inappropriate drawback of sampling amount of having avoided original sampler to produce because of the variation of flow pressure.

Embodiment
For further disclosing technical scheme of the present invention, elaborate by embodiment below in conjunction with Figure of description:
The present invention includes electric actuator 5, self-actuated controller 6, weight sensor 7, sampling housing 1, gland 3, sample tap, sealing-plug 2 and drive link 4, the housing that it is characterized in that taking a sample is made as cylindrical, center, the end is provided with oil supply hole, interior week is provided with box thread, be provided with a sample tap 8 in the bottom of middle part periphery, box thread is provided with the sealing-plug of threaded engagement, the top is provided with the gland 3 of flange connection or screwed connection, gland top is provided with the pressure cap that is threaded, and is provided with pressure pad and sealed packing between gland and pressure cap; Fix a columniform drive link at the sealing-plug center, drive link passes gland, and pressure pad is connected center pit and is connected with the copper sheathing of electric actuator with pressure cap; The copper sheathing junction of drive link and electric actuator is processed into square separately, is provided with the gap between the two, freely stretches out in the transmission roofbolt electric actuator copper sheathing; Be provided with a weight sensor in the bottom of sample tap, the control circuit of electric actuator is connected executive circuit and is connected with the control circuit of self-actuated controller with weight sensor;
The present invention's instruction that electric actuator 5 is sent according to self-actuated controller 6 in real work opens and closes the motor 11 of electric actuator 5,10 rotations of motor drives driven wheel, driven wheel drives copper sheathing 9 rotations, and drive link drives 2 rotations of plug blocking, opens the oil supply hole on the sampling housing 1.
The range limiter control that its stroke has electric actuator 5 to carry, when sealing-plug 2 rotates to the sample tap outside, this moment, electric actuator 5 was out of service, oil sample flows in the sampling jar by sample tap 8, time can be set according to need of production at random by the time controller of self-actuated controller, after finishing sample time, the motor of the time controller control electric actuator of self-actuated controller begins reverse rotation, sealing-plug reverse rotation under the drive of electric actuator, sealing-plug turns back to the sampling housing bottom, and the oil in the sampling housing 1 is arranged in pipe laying, so far, the single sampling is finished, and high-pressure sampling enters holding state automatically, waits for new round operation.
In the sampling container bottom, a weight sensor 7 is installed, sampling jar is placed on the weight sensor, when the sampling amount in the sampling jar reaches predetermined amount, weight sensor 7 passes to self-actuated controller 6 with signal, by self-actuated controller 6 signal is passed to electric actuator 5, the weight sensor weight signal and sample time controller the time signal control circuit make AND circuit, weight is preferentially moved.The effect that electronic scales is installed is (hypertonia) when preventing that pipe laying pressure from becoming large, causes sampling amount too much to overflow from sampling jar, and weight signal and time signal control circuit have had double insurance when selecting AND circuit to make high-pressure sampling.
The present invention is simple in structure, and is safe and reliable, and volume is little, and peace is main convenient, is subjected to the variable effects such as operating mode, dielectric viscosity, pressure little during sampling, especially for use in high pressure and pressure change sampling in the large situation can guarantee sampling amount accurately.
