Description
Technical field:
The utility model relates to the part that wood processing machinery is used, especially a kind of wood-split machine control valve.
Background technology:
In the prior art, the technology the most approaching with present patent application, be No. 00256371.1 patent of the applicant to China Intellectual Property Office's application and mandate, this patent disclosure a kind of wood processing machinery technical scheme with control valve, this control valve is that the hydraulic oil that adopts the rotation of valve rod to control oil inlet passage is the work done of oil discharge passage driven plunger, still return fuel tank by drainback passage, because valve rod needs to rotate, therefore valve pocket to be arranged, in use for some time, valve pocket will be worn to produce and become flexible, and will cause valve sleeve shifting, has destroyed the control function of control valve.In addition, the oil pressure of the hydraulic oil of the oil inlet passage of flowing through is uncontrollable, and oil pressure is too high sometimes will cause damage to entire machine.
Summary of the invention:
The utility model is exactly at the existing in prior technology deficiency, and a kind of wood-split machine technical scheme with control valve is provided, this scheme has adopted the fixation to valve pocket, guaranteed the stable of valve pocket, thereby guaranteed that the control function is not destroyed, in addition, between oil inlet passage and drainback passage, installed overflow valve additional, so can effectively guarantee the safe operation of machine effectively in order to the pressure of control oil inlet passage mesohigh oil.
This programme is realized by following technical measures.Mainly include valve body, handle set and handle, oil pocket and oil discharge passage are arranged in valve body, oil inlet passage and drainback passage communicate, the valve rod that band valve rod blind hole and valve rod oilhole are arranged in oil pocket, outside valve rod, be with the valve pocket of band valve pocket oilhole, openend at oil pocket also has valve stifled, the characteristics of this programme are to also have the stifled valve pocket that compresses of a valve pocket in described oil pocket, on valve pocket is stifled, there is cross-drilled hole corresponding with oil discharge passage, this cross-drilled hole also communicates with the stifled oilhole of valve pocket, the stifled oilhole of valve pocket is corresponding with the valve rod blind hole, in addition, overflow valve also is housed between oil inlet passage and drainback passage.Described overflow valve is to have relief valve seat to be inserted in the oil inlet passage, and there is oil-through hole to communicate with oil inlet passage, on relief valve seat, also have the draining hole to communicate with oil-through hole, the port of export in draining hole communicates with drainback passage and has the overflow spool to block outlet on relief valve seat, in addition, have voltage regulation screw to promote stage clip guide pillar extruding pressure spring, pressure spring promotes the overflow spool again.There is the stifled and overflow valve shutoff of relief valve seat on the top of described relief valve seat.Described stage clip guide pillar also is with guide column sleeve outward.Described voltage regulation screw also is with outward with the fixed cover of voltage regulation screw threaded engagement and is connected with guide column sleeve.
According to as can be known to the narration of such scheme, because it is stifled to have installed a valve pocket in the oil pocket in this scheme additional, the stifled top of this valve pocket compresses valve pocket again, and this structure can guarantee still can be fixed when wearing and tearing appear in valve pocket motionless, thereby has guaranteed valve rod effectively action of control machine when rotating.On valve pocket is stifled, there is cross-drilled hole corresponding with oil discharge passage, this cross-drilled hole also communicates with the stifled oilhole of valve pocket, the stifled oilhole of valve pocket is corresponding with the valve rod blind hole, this can make the hydraulic oil that is come by oil inlet passage enter oil inlet passage in the clear and go the plunger shaft work done, can make hydraulic oil enter the valve rod blind hole again, and leak into not work done of drainback passage by valve rod oilhole and valve pocket oilhole by the stifled oilhole of valve pocket.In addition, the overflow valve of control oil inlet passage hydraulic oil pressure is housed also between oil inlet passage and drainback passage, in order to guarantee the stable of oil inlet passage hydraulic oil pressure, this has just guaranteed the safe operation of machine.This shows that the utility model compared with prior art has substantive distinguishing features and progress, its implementation result also is conspicuous.
Description of drawings:
Fig. 1 is the part sectional structure schematic diagram of the utility model specific embodiment.
The specific embodiment:
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing as can be seen, the wood-split machine control valve of this programme, mainly include valve body 11, handle set 9 and handle 10, oil pocket 19 and oil discharge passage 20 are arranged in valve body 11, oil inlet passage 23 and drainback passage 6 communicate, the valve rod 12 that band valve rod blind hole 18 and valve rod oilhole 8 are arranged in oil pocket 19, outside valve rod 12, be with the valve pocket 13 of band valve pocket oilhole 7, openend at oil pocket 19 also has valve stifled 22, the characteristics of this programme are to also have a valve pocket stifled 21 to compress valve pocket 13 in described oil pocket 19, on valve pocket stifled 21, there is cross-drilled hole corresponding with oil discharge passage 20, this cross-drilled hole also communicates with the stifled oilhole 17 of valve pocket, the stifled oilhole 17 of valve pocket is corresponding with valve rod blind hole 18 again, in addition, between oil inlet passage 23 and drainback passage 6, the overflow valve that is used to control oil inlet passage 23 oil pressure is housed also.Described overflow valve is to have relief valve seat 16 parts to be inserted in the oil inlet passage 23, and there is oil-through hole 24 to communicate with oil inlet passage 23, on relief valve seat 16, also have draining hole 15 to communicate with oil-through hole 24, the port of export in draining hole 15 communicates with drainback passage 6 and has overflow spool 14 to block outlet on relief valve seat 16, in addition, have voltage regulation screw 2 to promote stage clip guide pillar 4 extruding pressure springs 5, pressure spring 5 promotes overflow spool 14 again, in order to regulate the pressure of overflow spool 14.The top of described relief valve seat 16 is useful on the relief valve seat stifled 26 of location and the overflow valve shutoff 25 that seals.The described stage clip guide pillar 4 outer guide column sleeves 3 that also are with.Described voltage regulation screw 2 outer also being with the fixed cover 1 that is used for voltage regulation screw 2 adjustings of voltage regulation screw 2 threaded engagement are connected with guide column sleeve 3.
