Abstract
A kind of combined control valve block for sequential control, oil inlet A on control block valve body is connected with the oil inlet of fluid-control one-way spool one, oil inlet A is connected to the control port of fluid-control one-way spool two, oil inlet B on the control block valve body is connected with the oil inlet of fluid-control one-way spool two, oil inlet B is connected with the control port of fluid-control one-way spool one, the oil outlet of two fluid-control one-way spools is connected with the oil inlet of the working hole of control block valve body and sequence spool, the oil outlet of sequence spool is connected with the working hole of control block valve body and next sequence spool oil inlet.The utility model solves gooseneck gland and is not required to open simultaneously or close for the problem that different Oil Field job requirements.
Description
Technical field
The utility model relates to petroleum operations ancillary equipment fields, in particular to combined control valve block.
Background technique
When continuous oil pipe device field operation, gooseneck enters and leaves injection head for oil pipe and primarily serves support and guiding work
With oil pipe one ends wound is above mentioned or transferred after importing injection head clamping region by gooseneck on roller.Operation process
In, in order to avoid oil pipe bounces out gooseneck, it is commonly designed that there are three cover pressing mechanism (upper, middle and lower) at the top of gooseneck, and need
Three hydraulic cylinders are wanted to control.Since oil pipe enters, gooseneck tube angulation is not identical with the variation of well head height, and gooseneck is most
At outer flare gland sometimes without turn off or only close the gland on the inside of the injection head, the liquid of traditional gooseneck gland
Compressing cylinder does not have sequential control mode, and three reversal valves can only be leaned on to control three oil cylinder switch motions, Yi Yinqi maloperation respectively
Cause oil pipe to pop up gooseneck, brings inconvenience to field operation, and the three cumbersome scenes of structure of reversing valve complexity pipeline layout
Maintenance conditions are inconvenient.
Summary of the invention
The purpose of this utility model is to provide a kind of combined control valve blocks for hydraulic cylinder sequential control, are used for needle
To different Oil Field job requirements, solve the problems, such as that gooseneck gland is not required to open simultaneously or close.
To achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of combined control valve block for sequential control, including control block valve body, fluid-control one-way spool one, fluid-control one-way
Spool two and more than two sequence spools, it is characterised in that oil inlet A and fluid-control one-way spool on the control block valve body
One oil inlet is connected, and oil inlet A is connected to the control port of fluid-control one-way spool two, the oil inlet on the control block valve body
Mouth B is connected with the oil inlet of fluid-control one-way spool two, and oil inlet B is connected with the control port of fluid-control one-way spool one, and two
The oil outlet of a fluid-control one-way spool is connected with the oil inlet of the working hole of control block valve body and sequence spool, sequence spool
Oil outlet is connected with the working hole of control block valve body and next sequence spool oil inlet.
The control block valve inner is additionally provided with drainback passage, the drainback passage be equipped with order of connection spool drain tap and
Link control module valve body oil inlet.
The setting inlet pressure of the sequence spool is each unequal.
The working hole quantity of control block valve body is for even number and 2 more than sequence spool quantity.
The utility model has the following beneficial effects:
1, the utility model can realize gland oil cylinder sequential control, to meet field operation requirement；
2, it is controlled using combinations such as a variety of spools, reduces valve member and pipe joint quantity, layout is simple, easy to operate；
3, when needing to control three with upper oil cylinder sequentially-operating, it is only necessary to increase pairs of sequence spool quantity,
It is simple and convenient.
Detailed description of the invention
Fig. 1 is the utility model control principle drawing；
Fig. 2 is the control logic figure of the one of embodiment of the utility model.
Specific embodiment
The utility model is described in further details with reference to the accompanying drawings and detailed description.
Referring to Fig. 1 and Fig. 2, by taking three oil cylinders of sequential control as an example:
Hydraulic oil is opened after control block valve A mouth oil inlet by fluid-control one-way spool 1 and fluid-control one-way spool 22
It opens, driving hydraulic cylinder I is closed, and driving pressure is default pressure, is more than the setting pressure of sequence spool 35 to hydraulic fluid pressure
After power, driving hydraulic cylinder II is closed, and is more than after sequence spool 1 sets pressure, to drive hydraulic cylinder III after hydraulic fluid pressure
It closes, hydraulic cylinder oil return is flowed out from fluid-control one-way spool 22；Hydraulic oil passes through liquid after control block valve B mouth oil inlet
It controls nonreturn valve core 22 and fluid-control one-way spool 1 is opened, driving hydraulic cylinder III is opened, and driving pressure is default pressure；
It is more than after sequence spool 46 sets pressure after hydraulic fluid pressure, driving hydraulic cylinder II is opened；It is more than sequence to hydraulic fluid pressure
After spool 24 sets pressure, driving hydraulic cylinder I is opened；Hydraulic cylinder oil return is flowed out from fluid-control one-way spool 1；Three oil cylinders
Closing sequence be I, II, III, opening sequence is III, II, I.
When needing to control three with upper oil cylinder sequentially-operating, it is only necessary to increase pairs of sequence spool quantity, letter
Folk prescription is just.
