The purpose of this utility model is achieved through the following technical solutions:
A kind of crude oil pipeline sampling head, including cylinder barrel, piston, drive end bearing bracket and rear end cap, drive end bearing bracket and rear end cap device respectively
At cylinder barrel two ends, piston apparatus seals in cylinder barrel endoporus and with endoporus and coordinates, and the bar portion of piston is through drive end bearing bracket and stretches out
In outside, it is characterised in that: there is the oil-in and oil-out, piston connected with cylinder barrel (3) endoporus cylinder barrel (3) side
(4) arrange on draw oil sample oil duct, rear end cap (2) is arranged sampling amount adjust piston (6), rear end cap (2) with take
Sample amount adjusts and arranges adjustment screw rod (1) between piston (6).
Cylinder barrel (3) side arranges the sample export (10) that communicates with endoporus, the circumferentially positioned oil duct on piston (4) by
The connection of heart section, radial section, surface section is constituted, and central segment is connected to the end face of piston (4), and surface section is in piston (4) vertically
On outer peripheral face, sample export (10) is corresponding in surface section.
Piston (4) outer surface has guide groove vertically, and cylinder barrel (3) side arranges the screwed hole communicated with endoporus, at this spiral shell
Being rotary with guide blot (14) on pit, the leading section of guide blot (14) is inserted in guide groove.
Sample export (10) connecting valve electromagnetic valve (11).
Also include that an electric pushrod (15), electric pushrod (15) are connected with the piston (4) of sampling head.
It is connected by forward and reverse connecting bolt (16) between described electric pushrod (15) and the piston rod of piston (4).
Described electric pushrod (15) electrically connects with microcomputer controller (17).
Compared with prior art, the technical solution of the utility model has the advantage that
This utility model uses electric pushrod as the reciprocating power of piston, sends sampling by microcomputer controller to electric pushrod
While instruction, switch electromagnetic valve also obtains valve opening instruction, and piston moves in end cap direction backward, and the sample oil in sample cavity is subject to
Extruding, is flowed out, when, after piston movement to front stop, piston nose sealing surface will hold out against close by sample export and switch electromagnetic valve
Gasket seals oil duct, even if now sampling instruction is not cancelled there will not be redundant sample outflow, for sampling thoroughly, turn-off time
General delayed sample time, meet the requirement of fixing sampling amount with this.This utility model overcomes original with hydraulic pressure as power
The defect that the hydraulic oil that sampler exists mixes with taken sample oil, it is ensured that the verity of taken sample；Single sampling amount is adjustable,
Meet the needs of client's difference operating mode, improve the level of crude oil sampling.
