Description
Technical field
This utility model relates to a kind of Hydraulic Relief Valve.
Background technology
Overflow valve is a kind of hydraulic pressure control valve, acts primarily as level pressure overflow effect, voltage stabilizing in hydraulic test, and system is unloaded
Lotus and safeguard protection effect.Level pressure overflow effect: in dosing pump flow restriction control system, dosing pump provides constant flow rate.
When system pressure increases, traffic demand can be made to reduce.Now overflow valve is opened, and makes excess traffic overflow oil sump tank, it is ensured that overflow
Valve inlet pressure, i.e. pump discharge pressure constant (valve port is often opened with pressure oscillation).Pressure stabilization function: overflow valve is connected on oil return line
On, overflow valve produces back pressure, and moving component stationarity increases.System unloaded effect: the remote control mouth at overflow valve concatenates the rill that overflows
The electromagnetic valve of amount, when the solenoid is energized, the remote control mouth of overflow valve leads to fuel tank, now hydraulic pump off-load.Overflow valve now conduct
Unloader uses.Safeguard protection effect: during system worked well, valve closing.Only load exceedes the limit (the system pressure of regulation
Power exceedes set pressure) time open overflow, carry out overload protection, make system pressure not be further added by (generally making the setting of overflow valve
Pressure ratio system maximum working pressure high 10%～20%).
The element easily producing noise in hydraulic means is commonly considered as pump and valve, again with overflow valve and electromagnetic switch in valve
Valves etc. are main.The factor producing noise is a lot.The noise of overflow valve has flow velocity sound and mechanic sound two kinds.Mainly by oil in flow velocity sound
The noise that the reasons such as liquid vibration, hole and hydraulic shock produce.Mainly by the shock of part in valve and friction etc. in mechanic sound
The noise that reason produces.
Current existing structure of relief valve less stable, regulation inconvenience, structural volume is bigger.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of compact conformation, and pressure is easy to adjust, structural stability
Higher Hydraulic Relief Valve.
For solving the problems referred to above, this utility model adopts the following technical scheme that
A kind of Hydraulic Relief Valve, including valve body, sleeve, tapered spool and threaded block, described sleeve is located in valve body, described
Sleeve is fixedly connected with the valve body, and described tapered spool is located at sleeve bottom, and described threaded block is located on sleeve, described threaded block with
Sleeve is fixing to be connected, and is provided with spring in described sleeve, and described spring is connected with tapered spool, is provided with spiral shell in described threaded block
Bar, is connected with spring bottom described screw rod, and described screw tip is provided with handwheel, and described handwheel is fixing with screw rod to be connected, described
Valve body side is provided with oil-in, and described body base is provided with oil-out, and described threaded block is provided with sealing ring, described close
Seal is connected with threaded block gluing.
As preferably, described sleeve is aluminium alloy sleeve barrel, keeps lightweight construction.
As preferably, described oil-in is in being horizontally disposed with.
As preferably, described oil-out is vertical setting.
As preferably, described tapered spool is slidably connected with sleeve so that tapered spool is easy to adjust.
As preferably, described screw rod is threadeded with threaded block, keeps screw rod easy to adjust.
As preferably, described spiro rod length is 12cm.
As preferably, described screw diameter is more than 8mm.
The beneficial effects of the utility model are: the tapered spool of setting can be permitted when fluid pressure is more than spring force
