Abstract
The utility model discloses a piston type deep well sampler, comprising a pipe body. The inner side of the pipe body is provided with a rotary type clock head, the rotary type clock head is contacted with the connecting rod body of a controller, and the rotary type clock head is provided with a groove. The connecting rod body of the controller is provided with the spacing balls of a control rod, the control rod is connected with the valve core of the control rod, and the valve core of the control rod is installed in the valve body of a one-way valve. The control rod is sheathed with springs, the pipe body arranged on one side of the one-way valve is provided with an oil inlet hole which is communicated with the one-way valve, and an oil storage cavity is arranged in the pipe body at the other side of the one-way valve. The oil channels arranged on both sides of the oil storage cavity are respectively provided with valves which are communicated with the outer side, and the inner side of the oil storage cavity is provided with a piston body. The utility model has reasonable structure, and the oil storage cavity of the sampler can be controlled to open at desired depth by the structure of the rotary type clock head. When sampling, the air enters from the valve of one end and pushes the piston body, and the sample can be taken out from the valve of the other end. Therefore, the sampling accuracy is effectively guaranteed and the sample has typical representation.
Description
Technical field:
The utility model relates to a kind of measurement or testing arrangement, is a kind of device of getting fluid sample or test liquid in boring or well.
Background technology:
Existing oil field deep well sampler is sold the general employing of using and is scraped wall type on the market, after its sampling, when sample is taken out, need oil sample be replaced out with another liquid, easily causes sample impure.
The disclosed technology of Chinese patent ZL03211859, though can on degree, improve sampling precision, but still have complex structure, the unfavorable problem of sampling precision.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, and can effectively guarantee sampling precision, makes sample have typical representational piston type deep-well sampler.
Technical solution of the present utility model is:
A kind of piston type deep-well sampler, body is arranged, dress rotary type hour in the body, rotary type hour contacts with the controller gonnecting rod body, rotary type is provided with groove on hour, it is characterized in that: the controller gonnecting rod body is provided with the spacing decorative pearl on top of an official cap of control lever, control lever is connected with the control lever spool, the control lever spool is contained in the one way valve valve body, pocketed springs on the control lever, the body of one way valve one side is provided with the fuel feed hole that communicates with one way valve, is provided with shoe cream room in the one way valve opposite side body, be respectively equipped with on the both sides oil duct of shoe cream room and the extraneous valve that communicates, be provided with piston body in the shoe cream room.
The utility model is rational in infrastructure, and by rotary type hour structure, controlled system sampler shoe cream room is opened in the required degree of depth, only need during sampling from an end valve, to enter, promote piston body, sample is taken out from another end valve with gas, effectively guaranteed sampling precision, made sample have typical case's representativeness.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of an embodiment of the utility model.
The specific embodiment:
A kind of piston type deep-well sampler, body 1 is arranged, dress rotary type hour 2 in the body 1, groove 3 was set on rotary type hour 2, rotary type hour 2 contacts with controller connecting rod 4 bodies, controller gonnecting rod body 4 is provided with the spacing decorative pearl on top of an official cap 5 of control lever, control lever 6 is connected with control lever spool 7, control lever spool 7 is contained in one way valve 8 valve bodies, pocketed springs 9 on the control lever 6, and the body of one way valve 8 one sides is provided with the fuel feed hole 16 that communicates with one way valve, are provided with shoe cream room 10 in the one way valve 8 opposite side bodys, be respectively equipped with on the both sides oil duct of shoe cream room 10 and the extraneous valve 11 that communicates, 12,13,14, be provided with piston body 15 in the shoe cream room 10.
During the utility model work, when hour turned to certain position, controller connecting rod 4 slipped in the groove 3, drive the decorative pearl on top of an official cap 5 displacements, control lever 6 is pulling control lever spool 7 under spring 9 effect, and oil sample enters the shoe cream room 10 from fuel feed hole 16, one way valve 8, and piston body 15 moves to the top.When the deep-well sampler takes out sampling from well, only need from an end valve 13,14, to enter, promote piston body 15, sample is taken out from another end valve 11,12 with gas.
