Abstract
The utility model relates to a dirt-proof self-locking multi-way valve. At present, in general hydraulic actuator, a hydraulic control one-way valve fails to solve problems of stability of the hydraulic actuator and dirt-proof and self-locking of a plurality of execution machines. The dirt-proof self-locking multi-way valve implements pressurization, decompression and self-locking of the load end by setting a hydraulic lock pushing rod and a lock pin in an oil reservoir connecting with the load end. Through designing a reversing valve bar into a plurality of segments with different diameters, which adjusts pressure of the oil reservoir of the load endand realizes series connection of a plurality of loads. The dirt-proof self-locking multi-way valve has the advantages of reasonable design, convenient usage, etc.
Description
Affiliated technical field
The utility model relates to a kind of anti-soil self-locking multi-way valve, and it is specially adapted to the hydraulic pressure installation of erector transport vehicle and combine-harvester.
Background technique
At present, on the market in the general hydraulic transmission, " Pilot operated check valve " great majority are that hydraulic pressure is unblanked, though possess some special knowledge on " hydraulic plunger " stuck problem, fail to solve the anti-soil problem in hydraulic actuator working stability and a plurality of actuators centralized control process.
Summary of the invention
The purpose of this utility model is to provide a kind of anti-soil self-locking multi-way valve, and it can solve the anti-soil and the self-locking of multi-way valve.
The utility model is achieved through the following technical solutions, and it comprises formations such as oil-feed valve body, commutation valve body, commutation valve rod, oil return valve body, safety valve, handlebar, hydraulic lock push rod, lock core, spring.
Be provided with lock core, hydraulic lock catch bar in the oil pocket that load end links to each other, the commutation valve rod is designed to different several sections of diameter
The utlity model has advantages such as reasonable in design, easy to use, anti-soil self-locking.
Description of drawings
Accompanying drawing 1 is looked sectional view for the utility model master.
Accompanying drawing 2 be in the accompanying drawing 1 G-G to sectional view
In the accompanying drawing, 1 for the oil-feed valve body, 2 for the commutation valve body, 3 for the commutation valve rod, 4 for the oil return valve body, 5 for safety valve, 6 for handlebar, 7 for the hydraulic lock push rod, 8 for lock core, 9 for spring, A be that load end, P are that filler opening, T are oil outlet.
Specific embodiment
As shown in drawings, the utility model is used among the elevating system of combine-harvester, elevating system in load end A and the reaper or other transmission system are connect, because of commutation valve rod 3 is designed to several sections of different-diameter, the section of different-diameter cooperates with oil circuit, form different oil circuits, thereby handle 6 can drive commutation valve rod 3 and seesaw and realize the variation of pressure oil circuit, the top of while handle 6 can promote hydraulic lock push rod 7 and travel forward, when the need supercharging, seesaw by promoting commutation valve rod 3, make chamber, lock core 8 place link to each other, thereby realize the purpose of supercharging with pressure oil cavity; When the need step-down, seesaw by promoting commutation valve rod 3, make the chamber at lock core 8 places link to each other, thereby realize the purpose of step-down with oil back chamber; When need are kept pressure when constant, make handlebar 6 leave hydraulic lock push rod 7 immediately, hydraulic pressure locking bar 7 is in free state, make lock core 8 under the promotion of the pressure oil in the chamber at spring 9 and lock core 8 places, lock core 8 rapidly stifled tight oil pockets, make that the pressure of load end A is constant, thereby realized the self-locking of load end A, guaranteed the stability of actuator.Can there be a plurality of load end A series connection to use in the utility model, realize supercharging, decompression or the self-locking of each load end A by the 6 pairs of hydraulic push rods 7 separately of handlebar and the position regulation of commutation valve rod 3 of being furnished with separately.In the utility model, safety valve 5 is according to the pressure of setting in advance, in case when reaching setting pressure, safety valve 5 is automatic pressure-relieving, thereby realized the purpose of safe adjusting.
