Abstract
The utility model discloses a handle which comprises a one-piece valve body (1), an O-ring (5), a plug (4), a valve core (2) and a screw type lining (3), wherein the one-piece valve body (1) has a valve core aperture (7) and a lining aperture (6), the valve core (2) is installed in the valve core aperture (7) from the top of the valve body, the plug (4) is connected with the valve core aperture (7) from the bottom of the screw type lining (3) in a sealing manner, the O-ring (5) is sleeved over the screw type lining (3), and the lining (3) is screwed in the lining aperture (6) via thread connection from the bottom of the one-piece valve body (1). The pilot handle is simple in structure, low in cost, and excellent in sealing effects.
Description
Technical field
The utility model relates to the hydraulic machinery field, particularly a kind of handle.
Background technique
Pilot handle is to be applied in the various hydraulic machineries, is used for the vitals of control multi-way valve.According to different hydraulic machinery performance requirements, by changing the stroke of handle spool, can satisfy flexibly the difference control requirement of different hydraulic machineries.In the industry, widely used is the end cover type pilot handle at present, and the structure of the end cover type pilot handle of prior art as shown in Figure 1.But the end cover type pilot handle has its obvious shortcoming:
(1) it is used for separating the lining 12 of P mouth 8, working hole 9, T mouth 10 cavities, because the use mallet beats the handle valve body 11 of packing into, so because workman's misoperation will be contained in extremely easily the O type circle galling in the lining 12 or cut in the process of knocking in, and extremely difficult discovery, cause and alter oil, and then cause security incident.
(2) because what adopt is end cap 13, valve body modular construction, first, because need processing, assembling end cap, increased product processing, the operation in the assembling, many one decks operation is with regard to many one decks disqualification rate and cost, and efficient is lower.The second, valve body and end cap because causing junction plane that scraping is arranged in processing or the assembly process, cause scratch unavoidably owing to be to assemble, and then affect the junction plane sealing effect, cause leakage of oil.
The model utility content
The technical problem that (one) will solve
Problem to be solved in the utility model prevents that the workman O type circle that will be contained in the lining from damaging, and causes security incident in assembly process; Improve the sealing effect of valve body and end cap.
(2) technological scheme
For addressing the above problem, the utility model provides a kind of handle, and described handle comprises integrated type valve body, O type circle, screw plug, spool and screw-in lining; Described integrated type valve body comprises spool bore, bush hole, the described spool spool bore of packing into from the valve body top, and described screw plug is tightly connected from screw-in sleeve and spool bore; Described screw-in lining cover has O type circle, and this lining is threaded connection from integrated type valve body bottom and screws in the bush hole.The lining of integral catch adopts and is threaded into the formula structure, milder when screwing in valve body, and mounting torque can accurately be controlled by torque wrench Overexertion and compression shock when so just having avoided installation, guarantee the good sealing of O type circle, greatly improved installation efficiency and installation quality.Owing to be integrated type end-cover-free valve body, so need not processing, assembling end cap, saved processing cost, avoided having the junction plane leakage of oil that causes because of end cap and valve body junction plane.
In above-mentioned a kind of handle, the H distance is that the spool adjustable stroke is 11mm between described spool bottom surface and the screw plug bottom surface.The spool adjustable stroke of general end cover type pilot handle is 4mm, and oil pressure curve adjustable extent is wider, greatly improved with hydraulic machinery in the matching degree of the required guide's oil pressure of multi-way valve.
(3) beneficial effect
Handle of the present utility model, (1) adopt the lining of integral catch to adopt and are threaded into the formula structure, have guaranteed the good sealing of O type circle, have greatly improved installation efficiency and installation quality.(2) owing to be integrated type end-cover-free valve body, saved processing cost, avoided having the junction plane leakage of oil that causes because of end cap and valve body junction plane.(3) integral catch is in the situation that volume reduces, but the spool adjustable stroke increases, and oil pressure curve adjustable extent is wider, greatly improved with hydraulic machinery in the matching degree of the required guide's oil pressure of multi-way valve.
Description of drawings
Fig. 1 is the structural drawing of the end cover type pilot handle of prior art;
Fig. 2 is the structural drawing of handle of the present utility model;
1 is that integrated type valve body, 2 is that spool, 3 is that screw-in lining, 4 is that screw plug, 5 is that O type circle, 6 is that bush hole, 7 is that spool bore, 8 is that P mouth, 9 is that working hole, 10 is the T mouth among the figure, and 11 is that valve body, 12 is that lining, 13 is end cap.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used for explanation the utility model, but are not used for limiting scope of the present utility model.
A kind of handle of the present utility model, as shown in Figure 2, described handle comprises integrated type valve body 1, O type circle 5, screw plug 4, spool 2 and screw-in lining 3; Described integrated type valve body 1 comprises spool bore 7, bush hole 6, described spool 2 spool bore 7 of packing into from the valve body top, and described screw plug 4 is tightly connected from screw-in lining 3 bottoms and spool bore 7; Described screw-in lining 3 covers have O type circle 5, and this lining 3 is threaded connection from integrated type valve body 1 bottom and screws in the bush hole 6.The lining 3 of integral catch adopts and is threaded into the formula structure, milder when screwing in valve body, and mounting torque can accurately be controlled by torque wrench Overexertion and compression shock when so just having avoided installation, guarantee the good sealing of O type circle, greatly improved installation efficiency and installation quality.Owing to be integrated type end-cover-free valve body, so need not processing, assembling end cap, saved processing cost, avoided having the junction plane leakage of oil that causes because of end cap and valve body junction plane.
In above-mentioned a kind of handle, distance H is that spool 2 adjustable strokes are 11mm between described spool 2 bottom surfaces and screw plug 4 bottom surfaces.Spool 2 adjustable strokes of general end cover type pilot handle are 4mm, and oil pressure curve adjustable extent is wider, greatly improved with hydraulic machinery in the matching degree of the required guide's oil pressure of multi-way valve.
During installation, by torque wrench screw-in lining 3 is got final product from integrated type valve body 1 bottom alignment bush hole 6 mild screw-ins, described screw plug gets final product from integrated type valve body 1 bottom to spool bore 7 mild screw-ins by torque wrench.
Handle of the present utility model adopts the lining employing of integral catch to be threaded into the formula structure, has guaranteed the good sealing of O type circle, has greatly improved installation efficiency and installation quality.Owing to be integrated type end-cover-free valve body, saved processing cost, avoided having the junction plane leakage of oil that causes because of end cap and valve body junction plane.Integral catch is in the situation that volume reduces, but the spool adjustable stroke increases, and oil pressure curve adjustable extent is wider, greatly improved with hydraulic machinery in the matching degree of the required guide's oil pressure of multi-way valve.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
