Abstract
The utility model is provided installs conical valve base in a kind of Hydraulic Relief Valve for throttling, valve body, poppet valve core is provided with conical valve base, poppet valve core connecting spring, the spring other end connects adjusting pin, and throttle orifice is provided with valve body, and adjustable throttling core passes through anterior bolt and installed with throttle orifice screw-internal thread fit.The Hydraulic Relief Valve for throttling of the present utility model, on the basis of overflow valve relief function, increased an adjustable throttling function again, and reducing system pressure increases suddenly the impact for causing；Relief valve spool uses cone valve, and with guide function, when it is moved back and forth, it is ensured that its direction, reduces and deviate the noise that proper motion direction is caused.
Description
Technical field
The utility model is related to valve technology field, more particularly to Hydraulic Relief Valve field.
Background technology
Overflow valve plays safety effect, there is provided overvoltage protection, and when hydraulic oil exceedes Opening pressure, overflow valve is opened, and is played
Unloading pressure protection is acted on.Existing overflow valve, can only realize relief function, and overflow Opening pressure is all non-adjustable, in its reciprocating motion
When, deviateing proper motion direction can produce noise.Also, system pressure can be impacted when increasing suddenly.
Utility model content
In order to solve the problems such as being impacted when the irreconcilable system pressure of overflow Opening pressure increases suddenly, this practicality is new
Type provides a kind of Hydraulic Relief Valve for throttling.
The technical scheme that the utility model is used to achieve the above object is：A kind of Hydraulic Relief Valve for throttling, valve
Installed in body 1 and poppet valve core 5 is provided with conical valve base 6, conical valve base 6, the connecting spring 4 of poppet valve core 5, the other end of spring 4 connection adjusting pin
3。
Throttle orifice 7 is provided with the valve body 1, adjustable throttling core 2 passes through anterior bolt and pacifies with the screw-internal thread fit of throttle orifice 7
Dress.
The Hydraulic Relief Valve for throttling of the present utility model, on the basis of overflow valve relief function, increased one again
Adjustable throttling function, reducing system pressure increases suddenly the impact for causing；Relief valve spool uses cone valve, and with leading
To function, when it is moved back and forth, it is ensured that its direction, reduce and deviate the noise that proper motion direction is caused.
Brief description of the drawings
Fig. 1 is the utility model Hydraulic Relief Valve structure chart.
In figure：1st, valve body, 2, adjustable throttling core, 3, adjusting pin, 4, spring, 5, poppet valve core, 6, conical valve base, 7, throttling
Hole.
Specific embodiment
The hydraulic overflow valve arrangement for throttling of the present utility model is as shown in figure 1, body is a cast iron valve body 1, and other are each
Individual element is all placed in this valve body 1.Installed in valve body 1 and poppet valve core 5 is provided with conical valve base 6, conical valve base 6, the connection bullet of poppet valve core 5
Spring 4, the other end of spring 4 connection adjusting pin 3 is provided with throttle orifice 7 in valve body 1, adjustable throttling core 2 passes through anterior bolt and throttling
The screw-internal thread fit of hole 7 is installed.
Spring 4 is connected to adjusting pin 3 and poppet valve core 5, when the hydraulic fluid pressure acted on poppet valve core exceedes the compression of spring
During pressure, spring is compressed, and poppet valve core 5 is moved to the direction of spring 4, and the logical hydraulic fluid port of overflow valve is opened, and hydraulic oil is flowed through, and system is unloaded
Pressure, the connecting spring 4 of adjusting pin 3 rotates adjusting pin 3, thus it is possible to vary the decrement of spring 4, and then change the unlatching of overflow valve
Pressure.Conical valve base 6 plays fixed poppet valve core 5 and acts on, and when poppet valve core 5 is moved, play the guiding role, it is to avoid poppet valve core 5 deviates just
The normal direction of motion.Relief valve spool uses cone valve, and with guide function, when it is moved back and forth, it is ensured that its direction,
Reduce and deviate the noise that proper motion direction is caused.Adjustable throttling core 2 adjusts the size of throttle orifice 7, adjustment by swivel bolt
Amount of restriction.
On the basis of basic overflow, the utility model realizes adjustable throttling to the utility model, reduces system pressure and dashes forward
So increase the impact for causing, the guide function of conical valve base decreases impact noise when poppet valve core 5 is moved.
