Description
Technical field
The utility model belongs to drainage device technical field, more particularly, to a kind of quick drainage device of hydraulic control.
Background technique
Traditional quick drainage device requires the machining tolerance of pass very stringent.The quick drainage device of tradition, by valve
The O-ring seal on valve rod, spring, steel ball and multiple spools composition is arranged in body, valve rod.Due to processing faying face with valve body
Locate machining accuracy and valve rod pass machining tolerance require it is very high, if processing can be generated in hydraulic system beyond tolerance and be let out or card valve
The problems such as, and it is also very high to the level requirement of assembly spool personnel when valve rod on the right side of assembly, when assembly, must careful valve
O-ring seal on bar knocks damage by the horizontal oil duct of hydraulic fluid port III, there are also be exactly special processing spool quantity it is more, machining accuracy is wanted
Ask higher.
Summary of the invention
The purpose of the utility model is to provide a kind of tolerance is low, draining performance is relatively reliable, and leakproofness is better
The quick drainage device of hydraulic control.
The purpose of this utility model is realized by following technical proposals:
The quick drainage device of the hydraulic control of the utility model, including cavity are arranged in the hydraulic fluid port I on this cavity, are located at
The hydraulic fluid port II and hydraulic fluid port III of I two sides of hydraulic fluid port, it is characterised in that individual event valve body, setting are set in II side of hydraulic fluid port
The valve body O-ring seal of the individual event valve valve end is arranged in flap on this individual event valve valve end, is arranged described
The valve rod of III side of hydraulic fluid port is arranged in the spring of individual event valve body tail portion, the silk plug I being connected with this spring, and setting exists
O-ring seal on the valve rod, be connected silk plug II with the tail portion of the valve rod.
The valve rod is arranged in the mounting hole of III side of hydraulic fluid port, and buffering chamfering is equipped in this mounting hole.
The advantages of the utility model:
The quick drainage device of the hydraulic control of the utility model, using check valve unitary design, check valve body and flap make close
Envelope property is better, and uses valve body O-ring seal, makes the reduction of pass machining tolerance；And hole type design is optimized,
The pass for assembling the valve rod of sealing ring with o has buffering chamfering, makes not having to consider that O-ring seal is damaged when assembly, makes quickly to let out
Oiliness can be relatively reliable, and also re-optimization designs spool, reduces the quantity of traditional valve core.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is further illustrated with reference to the accompanying drawing.
As shown in Figure 1, the quick drainage device of the hydraulic control of the utility model, including cavity, the hydraulic fluid port I on this cavity is set
1, it is located at the hydraulic fluid port II 2 and hydraulic fluid port III 3 of I 1 two sides of hydraulic fluid port, it is characterised in that be arranged in II 2 side of hydraulic fluid port
The flap 5 on this 11 end of individual event valve body is arranged in individual event valve body 11, and the valve of 11 end of individual event valve body is arranged in
The spring 4 of 11 tail portion of individual event valve body, the silk plug I 12 being connected with this spring 4, setting is arranged in body O-ring seal 10
Valve rod 8 in III 3 side of hydraulic fluid port, is arranged in the O-ring seal 9 on the valve rod 8, is connected with the tail portion of the valve rod 8
Connect silk plug II 6.
The valve rod 8 is arranged in the mounting hole of III 3 side of hydraulic fluid port, and buffering chamfering 7 is equipped in this mounting hole.
Individual event valve body 11 and flap 5 are first inserted into II 2 side mounting hole of hydraulic fluid port and shift bottom by the utility model, are put into
Spring 4 screws on silk plug I 12；Valve rod 8 is installed into O-ring seal 9 from III 3 side of hydraulic fluid port insertion mounting hole again, screws on silk plug II 6,
Assembly finishes.It when hydraulic oil is in II 2 mouthfuls of inflows of hydraulic fluid port by flap 5 and valve body O-ring seal 10, generate hydraulic oil will not
Leakage；When hydraulic oil is when hydraulic fluid port III 3 flows into, promotion valve rod 8 opens flap 5, and hydraulic oil can be released from hydraulic fluid port II 2 to oil
Mouth I 1 realizes the quick oil draining function of hydraulic control.
The quick drainage device of the hydraulic control of the utility model, using check valve unitary design, individual event valve body 11 and flap 5
Keep leakproofness better, and use valve body O-ring seal 10, makes the reduction of pass machining tolerance；And optimize hole
Type design, the pass for assembling the valve rod 8 of sealing ring 9 with o have buffering chamfering 7, make not having to consider that O-ring seal 9 is broken when assembly
Damage, keeps quick draining performance relatively reliable, and also re-optimization designs spool, reduces the quantity of traditional valve core.
