Description
Technical field
The utility model relates to hydraulic pump technical fields, are a kind of air-driven hydraulic pump intake valves specifically.
Background technique
Air-driven hydraulic pump is hydraulic motion in being pumped using certain gas compression gas push, realizes the one of power output function
Kind novel device, basic functional principle are to utilize large area piston end by the reciprocating motion of the pistons in air-driven hydraulic pump
Low pressure generate small area piston end height it is hydraulic, lower air pressure is converted into high pressure oil, then cooperate with hydraulic cylinder
Component completes driving process.Compared to traditional electric hydraulic pump, air-driven hydraulic pump have clean energy resource, without electric spark and flame,
The features such as use cost is cheap, small in size and product is light and handy, be widely used in metallurgy, mine, ship, machinery, petrochemical industry,
The fields such as auto repair, particularly suitable underground coal mine have the occasion of requirement of explosion proof to use.
Important component of the intake valve as air-driven hydraulic pump, structural behaviour directly influence the work lotus of air-driven hydraulic pump
Load, operating rate and its service life.Currently, the intaking valve structure of air-driven hydraulic pump is complicated, intake efficiency is not high, service life
It is short, and common iron or stainless steel material are mostly used, processing cost is high, and easily gets rusty and block oil circuit, leads to air-driven hydraulic pump
Cisco unity malfunction.
Utility model content
The purpose of the utility model is to overcome deficiencies in the prior art, provide a kind of air-driven hydraulic pump intake valve,
Have many advantages, such as structure simple, long service life, at low cost, while can be realized quick air inlet, and gas is close in intake valve
It is good to close effect.
To achieve the goals above, the utility model takes technical solution below: a kind of air-driven hydraulic pump intake valve,
Shape is rectangular parallelepiped structure, and the valve inner of intake valve is provided with valve body type chamber vertically and horizontally, vertical direction
Valve body type is intracavitary to be provided with valve rod, is provided with O-shaped sealing at the upper and lower part hole between the valve rod and valve body type chamber
Circle, respectively the first O-ring seal and the second O-ring seal, stem bottom are cased with core cap；Intracavitary point of the valve body type of horizontal direction
It is not provided with circlip retaining ring, composite filter net and Plastic cap, circlip retaining ring is arranged before composite filter net, plays fixed multiple
Close the effect of filter screen.
As an improvement the air-driven hydraulic pump intake valve design, which has, is easily installed fixed ladder hole, ladder
Through-hole is symmetric.
As an improvement the valve stem top of air-driven hydraulic pump intake valve is arc-shaped, arc diameter is Φ 6mm
~Φ 15mm.
As an improvement the valve rod of the air-driven hydraulic pump intake valve uses 45# steel material.
As an improvement the first O-ring seal and the second O-ring seal of air-driven hydraulic pump intake valve are silicon
One kind of glue or nitrile rubber material.
As an improvement the combined filtration screen distance of air-driven hydraulic pump intake valve is 0.2mm~1.5mm.
As an improvement the valve body of the air-driven hydraulic pump intake valve uses aluminum alloy material.
A kind of air-driven hydraulic pump intake valve described in the utility model has structure simple, and air-tightness is good, service life
The features such as long；The valve stem top of intake valve uses designed arc-shaped appearance, reduces the identical precision of work, while reducing external force and applying by force
Degree, is conducive to the quick unlatching of valve rod air inlet；Entire valve body uses aluminum alloy material, had not only reduced product difficulty of processing but also had mitigated
Valve weight also avoids getting rusty；Valve rod uses 45# steel material, it is ensured that its use intensity avoids deformation from generating；It is horizontal
Direction uses Plastic cap, mainly prevents the sundries such as dust, particle from entering valve body type intracavitary, when in use can take Plastic cap
Under, access admission line.
Detailed description of the invention
Fig. 1 is the cross-sectional view of the utility model air-driven hydraulic pump intake valve；
Fig. 2 is the top view of Fig. 1.
Specific embodiment
The utility model is described in further detail with embodiment with reference to the accompanying drawing: as shown in Fig. 1~2: described
Air-driven hydraulic pump is rectangular parallelepiped structure with intake valve, and designs to have and be easily installed fixed ladder hole 9, the ladder hole 9
It is symmetric；The valve inner of intake valve is provided with valve body type chamber vertically and horizontally, the valve body type of vertical direction
It is intracavitary to be provided with valve rod 3, it is arc-shaped at the top of valve rod 3, arc diameter is Φ 6mm~Φ 15mm, and valve rod 3 uses 45# steel material；
It is O-shaped close that the first O-ring seal 4 and second is respectively arranged at upper and lower part hole between the valve rod 3 and valve body type chamber
Seal 2, first O-ring seal 4 and the second O-ring seal 2 are one kind of silica gel or nitrile rubber material；The valve rod 3
Bottom is cased with core cap 1；The valve body type of horizontal direction is intracavitary to be respectively arranged with circlip retaining ring 5, composite filter net 6 and Plastic cap 7,
