Background technology
Along with the fast development of society, the rapid advances of science and technology, hydraulic valve is used for the every field such as industry agricultural, hydraulic pressure
Valve is the Automation Elements of a kind of pressure oil operation, and it is controlled by distributing valve pressure oil, generally combines with electromagnetic distributing valve
Use, can be used for distant control power station oil, the break-make of gas and water pipe-line system, be usually used in clamping, control, the oil circuit such as lubrication,
Have direct acting type and type pilot point, multiplex type pilot, the basic structure of hydraulic valve mainly includes that spool, valve body and driving spool exist
The manipulation device done relative motion in valve body, the principal mode of spool has guiding valve, cone valve and ball valve, and valve body is joined with spool except having
Close valve body hole or valve seat orifice outside, also external oil pipe into and out of hydraulic fluid port and drain tap;Spool is driven to do fortune relatively in valve body
Dynamic device can be hand adjustment mechanism, it is also possible to being spring or electric magnet, some occasion also uses hydraulic coupling to drive, former in work
In reason, hydraulic valve is the size of the relative motion utilizing spool in valve body break-make and opening to control valve port, to realize pressure
Power, flow and direction controlling, but traditional hydraulic valve there is also deficiency in terms of Based Intelligent Control, hydraulic valve is in connection procedure
Sealing there is also defect hydraulic valve, also has deficiency in detection in terms of hydraulic valve flow.Therefore, one is proposed for the problems referred to above
Plant self-locking type hydraulic valve.
Utility model content
The purpose of this utility model is that provides a kind of self-locking type hydraulic valve to solve the problems referred to above.
This utility model is achieved through the following technical solutions above-mentioned purpose, a kind of self-locking type hydraulic valve, including shell with
And it being arranged on the connecting tube of described shell side, fixed seal ring is installed in described connecting tube side;Described side wall of outer shell welding tooth
Roller box, and described gear-box one end arranges manual rotary valve;Described enclosure arranges back-moving spring, and described back-moving spring one
End installs Magnet;Described Magnet side arranges spool and fixes seat, and described spool fixes the internally installed spool of seat;Described spool is solid
Reservation one end arranges PLC, and described PLC one end connects intervalometer.
Preferably, also including on and off switch and current capacity statistics, described side wall of outer shell installs on and off switch, described shell side
Wall arranges current capacity statistics, and described on and off switch and described current capacity statistics are in approximately the same plane.
Preferably, described fixed seal ring and described connecting tube all have two, and are symmetrically installed about described shell.
Preferably, described spool is installed between described shell and described spool and fixes seat.
Preferably, described back-moving spring centrage and described magnet centerline, described center spool line are all straight at same
On line.
Preferably, in described PLC and described intervalometer, described on and off switch, described current capacity statistics
It is electrically connected with between portion.
The beneficial effects of the utility model are: this kind of self-locking type hydraulic valve utilizes spool motor control valve body in valve body to lead to
Disconnected, simple in construction, easy to operate, the break-make of Based Intelligent Control the most manually controllable hydraulic valve simultaneously can be realized, setting fixing close
Seal can effectively connect conduit, and can be good at sealing, and controls spool by Magnet and effectively simplifies hydraulic valve
Structure, can effectively control hydraulic valve make-and-break time by the intervalometer arranged, it is achieved the self-closing performance of hydraulic valve, make function more
Adding perfect, the current capacity statistics of setting can add up the flow through hydraulic valve intuitively, has good social benefit and economy
Benefit, is suitable for promoting the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise
The every other embodiment obtained, broadly falls into the scope of this utility model protection.
Referring to shown in Fig. 1-2, a kind of self-locking type hydraulic valve, including shell 10 and be arranged on described shell 10 side
Connecting tube 7, fixed seal ring 11 is installed in described connecting tube 7 side;Described shell 10 sidewall weld gear-box 2, and described gear
Case 2 one end arranges manual rotary valve 1;The internal back-moving spring 9 that arranges of described shell 10, and described back-moving spring 9 one end installation magnetic
Ferrum 3;Described Magnet 3 side arranges spool and fixes seat 4, and described spool fixes the internally installed spool of seat 48;Described spool 8 is fixed
Seat one end arranges PLC 5, and described PLC 5 one end connects intervalometer 6.
As a kind of technical optimization scheme of the present utility model, also include on and off switch 12 and current capacity statistics 13, described
Shell 10 sidewall installs on and off switch 12, and described shell 10 sidewall arranges current capacity statistics 13, and described on and off switch 12 and institute
State current capacity statistics 13 in approximately the same plane, make functions of the equipments more perfect.
As a kind of technical optimization scheme of the present utility model, described fixed seal ring 11 all has two with described connecting tube 7
Individual, and be symmetrically installed about described shell 10, make sealing effectiveness more preferable.
As a kind of technical optimization scheme of the present utility model, between described shell 10 and described spool 8, described valve is installed
Seat 4 fixed by core, simplifies structure.
As a kind of technical optimization scheme of the present utility model, described back-moving spring 9 centrage and described Magnet 3 center
Line, described spool 8 centrage, all on same straight line, make operation more reasonable.
As a kind of technical optimization scheme of the present utility model, described PLC 5 and described intervalometer 6, institute
