Abstract
Hydrostatic steering system check valve structure relates to a check valve. This check valve is including the casing that has first draw -in groove and second draw -in groove, the sealed lid that has first joint end and second joint end, the valve and the spring that have the draw -in groove, the first joint end joint of sealed lid is in the first draw -in groove of casing, the second joint end joint of sealed lid is in the second draw -in groove of casing, casing and sealed lid riveting, the spring joint is between valve and casing, the spring force makes the first side wall of valve, the second lateral wall contacts with the sealed inner wall that covers, the outer wall of casing and the contact of power steering's oil inlet inner wall, the power steering oil inlet, the oil inlet of sealed lid, the valve opening communicates each other, casing lower extreme opening and oil duct intercommunication. This structure can directly set up the seal structure who lies in the inlet port and seal structure to the intercommunication the oil duct between, its simple structure, simple to operate, the installation and maintenance of being convenient for to the cost of manufacture has been practiced thrift.
Description
Technical field
The utility model relates to a kind of check valve, particularly a kind of hydrostatic steering system one-way valve structures.
Background technology
Hydrostatic steering system needs to mate on stream, in order to obtain better turning efficiency, sometimes need to increase check valve in systems in which, as shown in Figure 1, common structure is for be integrated into inside logical oil draining bolt 3 by check valve, and logical oil draining bolt 3 is through the high pressure oil inlet place being arranged on power steering 1 after steering oil pipe 2.This kind of constructional delails is more, and cost is higher.
Summary of the invention
The utility model provides a kind of hydrostatic steering system one-way valve structures, solves check valve just must can navigate to power steering admittedly problem by logical oil draining bolt, and its structure is simple, easy for installation, be convenient to realize.
The technical scheme that the utility model adopts is as follows: a kind of hydrostatic steering system one-way valve structures, comprise the housing with the first draw-in groove and the second draw-in groove, with the seal cover cap of the first joint end and the second joint end, with valve and the spring of draw-in groove, first joint end of seal cover cap is connected in the first draw-in groove of housing, second joint end of seal cover cap is connected in the second draw-in groove of housing, housing and seal cover cap are riveted, Spring Card is connected between valve and housing, spring force makes the first side wall of valve, second sidewall and seal cover cap contact internal walls, the outer wall of housing and the oil inlet contact internal walls of power steering, power steering oil inlet, the oil inlet of seal cover cap, valve openings communicates with each other, housing lower ending opening is communicated with oil duct.
As a kind of optimal way of the present utility model, hydrostatic steering system check valve be arranged on hermetically-sealed construction in fuel feed hole and with hermetically-sealed construction between the oil duct be communicated with.
Advantage of the present utility model and effect: this check valve comprises with the housing of the first draw-in groove and the second draw-in groove, the seal cover cap with the first joint end and the second joint end, the valve with draw-in groove and spring, can be set directly between hermetically-sealed construction in fuel feed hole and the oil duct be connected with hermetically-sealed construction, its structure is simple, easy for installation, be convenient to installation and maintenance, and save cost of manufacture.
Accompanying drawing explanation
Fig. 1 is existing hydrostatic steering system one-way valve structures schematic diagram;
Fig. 2 is the utility model hydrostatic steering system one-way valve structures schematic diagram;
Sequence number illustrates: 1 deflector, 2 steering oil pipes, 3 logical oil draining bolt, 4 seal cover caps, 4-1 first draw-in groove, 4-2 second draw-in groove, 4-3 oil inlet, 5 valves, 5-1 the first side wall, 5-2 second sidewall, 6 housings, 6-1 first joint end, 6-2 second joint end, 6-3 opening, 7 springs.
Detailed description of the invention
Below in conjunction with accompanying drawing 2, structure of the present utility model is further described.
A kind of hydrostatic steering system one-way valve structures, comprise with the housing of the first draw-in groove 4-1 and the second draw-in groove 4-2, seal cover cap, valve 5 and the spring 7 with the first joint end 6-1 and the second joint end 6-2, first joint end card 4-1 of seal cover cap 4 is connected in the first draw-in groove 6-1 of housing 6, second joint end 4-2 of seal cover cap 4 is connected in the second draw-in groove 4-2 of housing 6, and housing 6 and seal cover cap 4 are riveted.Spring 7 is connected between valve 5 and housing 6, spring force makes the first side wall 5-1, the second sidewall 5-2 and seal cover cap 4 contact internal walls of valve 5, the outer wall of housing 6 and the oil inlet contact internal walls of power steering, power steering oil inlet, the oil inlet 4-3 of seal cover cap 4, valve communicate with each other, and housing 6 lower ending opening 6-3 is communicated with oil duct.
Hydrostatic steering system non-return valve operational process in the present embodiment is: oil body (adopts copper plug through the fuel feed hole of deflector, hermetically-sealed construction in the present embodiment, this copper plug is connected in fuel feed hole, the round platform be positioned at bottom copper plug is connected on the table top of steering gear housing) centre hole enter hydrostatic steering system check valve, valve opening, oil body enters valve extrusion spring 7 makes spring 7 compress, between seal cover cap 4 and valve 5, form oil body passage, oil body enters oil duct through housing 6 lower ending opening 6-3.
Although the foregoing describe detailed description of the invention of the present utility model, but the those skilled in the art in this area are to be understood that, these are only casehistorys, can make various changes or modifications, and do not deviate from principle of the present utility model and essence to these embodiments.Scope of the present utility model is only defined by the appended claims.
