Description
Technical field
The present invention relates to hydraulic valve technology, especially a kind of connection structure of Combined valve.
Background technique
Combined valve is widely used in the field of hydraulic control of various engineering machinery, industrial machinery and agricultural machinery.With
The increase for needing to control hydraulic device quantity can reduce the processing and manufacturing difficulty of single valve using Combined valve, to be formed
Standardized production reduces the cost manufactured with inventory's stock, and has preferable scalability, is suitable for new equipment and researches and develops
Or the upgrading of matured product improves.The connection structure of existing valve block system is that fastener is simply provided in valve block mostly
Four corners, the fastener dynamic fatigue that the frequent charge and discharge hydraulic coupling variation of hydraulic system will cause loosens, to make equipment
Leakproofness and reliability reduce.
Summary of the invention
The applicant is easy to generate pine due to dynamic fatigue for the fastener of the connection structure of above-mentioned existing Combined valve
The disadvantages of moving, reducing leakproofness and reliability provides a kind of connection structure of structurally reasonable Combined valve, fastener is set
It sets around oil inlet nozzle and oil return nozzle, coupling mechanism force can be provided with line up, improve the sealing effect and reliability of equipment.
The technical solution adopted in the present invention is as follows:
A kind of connection structure of Combined valve, at least two valve blocks are applied in combination, and adjacent two valve block is allowed to by fastening structure
It is docked in endface, the fixation hole number around high pressure pipe mouth is more than the fixation hole around low pressure nozzle.
As a further improvement of the above technical scheme:
The fixation hole is through-hole, and each valve block is respectively provided with the through-hole of perforation, and component of rod category passes through through-hole and connects valve block.
The fixation hole is threaded hole, and the valve block that end or centre is arranged in opens up threaded hole, and other valve blocks open up through-hole,
Component of rod category passes through the through-hole of all valve blocks and threaded hole locks all valve blocks.
It is equipped with the through-hole and threaded hole of several perforations simultaneously on a side end face of transition block.
The one or both ends of through-hole are counterbore.
Beneficial effects of the present invention are as follows:
Fixation hole, fixation hole provided around high pressure pipe mouth (oil inlet pipe) are arranged in each valve block using Combined valve of the invention
More than the fixation hole around low pressure nozzle (oil return pipe).On the oil inlet nozzle periphery of high pressure, more fixation hole is set, it can be effective
The leakproofness for guaranteeing oil inlet pipe, is arranged less fixation hole on the oil return nozzle periphery of low pressure, also can satisfy low pressure nozzle
Seal request.Fixation hole can be the through-hole being correspondingly arranged between each valve block, by bolt by each valve block connect into one it is whole
Body, it is easy to operate, and can guarantee sealed precision；Fixation hole is also possible to part valve block setting threaded hole, and part is arranged
The valve block for being provided with through-hole is connected in the valve block of setting threaded hole by bolt, finally connects into an entirety knot by through-hole
Structure.Through-hole, bolt and nut are respectively positioned on the inside of valve block, will not impact to external element is arranged in, practicability is good.This
Fastener is set up directly on oil inlet nozzle or oil return nozzle periphery by invention, rather than the four corners in valve block are simply provided,
Both the reasonable utilization inner space of valve block, while coupling mechanism force can also be provided with line up sealing device, it avoid frequent fill
Fastener dynamic fatigue caused by tapping pressure change loosens, and effectively increases the sealing effect and reliability of equipment.
