Abstract
The utility model relates to an oil regulating valve which is a valve structure. The utility model is widely used for flow quantity and pressure regulation of different kinds of oil, such as fuel oil, lubrication oil, fire resistant oil, etc., in industries, such as power stations, petrochemical industry, metallurgy, etc. The oil regulating valve comprises a valve body and a valve cap arranged at the upper part of the valve body, an inlet and an outlet which are arranged on the valve body, and an oil regulating mechanism arranged in the valve body, wherein the oil regulating mechanism comprises a valve seat, a throttle ring arranged on the valve seat, and a flow equalization hood arranged on the valve seat, which are orderly arranged in the inlet and an outlet. Valve cores are arranged in the throttle ring and the flow equalization hood, and the upper ends of the valve cores are connected with valve rods. The utility model can realize multistage throttle, and has the advantages of stable running, low noise, remote possibility of leakage and long service life.
Description
Technical field
The utility model oils modulating valve relates to a kind of valve arrangement, is widely used in various oils flows and pressure adjustings such as industry intermediate fuel oil, lubricant oil, fire-resistant oils such as power station, petrochemical industry, metallurgy.
Technical background
The oils modulating valve is according to the different needs of operating mode, the oils modulating valve has High Pressure Difference and two kinds of structures of low differential pressure, and the present oils modulating valve that uses is because used material is different with structure, the performance difference of product is very big, and subject matter is: noise is big, vibration is big, easily leak, working life is short.
Summary of the invention
The purpose of this utility model is: provide a kind of and operate steadily, vibrate little, as to be difficult for leakage, long service life oils modulating valve.
For reaching above-mentioned purpose, a kind of oils modulating valve of the utility model, comprise valve body and the valve gap that is installed in valve body top, be located at the import and export on the valve body, the oils controlling mechanism is installed in the valve body, wherein, described oils controlling mechanism is included in the restrictor ring of importing and exporting interior valve seat, being located at the valve seat top, be located at the current-sharing cover of restrictor ring top, be provided with cylindrical spool in the current-sharing cover, spool top connects valve rod.The oils modulating valve is according to the different needs of operating mode, and the oils modulating valve has High Pressure Difference and two kinds of structures of low differential pressure, adopts the current-sharing cover on restrictor ring and top to constitute throttling element, changes the restrictor ring passage section by the spool lifting and realizes the fuel flow adjusting.Because the structural feature of throttling element makes fuel tap become multistage step-down by the one-level step-down, thereby this valve is operated steadily, noise is low, vibration is little, can keep does not for a long time have leakage.Low differential pressure oils modulating valve adopts the current-sharing cover structure, and the cross-sectional flow area by spool lifting change current-sharing cover realizes the adjusting of oily flow.Because pressure reduction is low, so noise and erosion are also smaller, long service life.
On the such scheme basis, described spool is the awl column construction, and spool and valve base chamber are handled with solid solution craft, and operation is firmly vibrated for a short time, and noise is low.
Perhaps, described spool is the awl column construction, and the lower end is the conical surface.
In the utility model, described import and export are straight-through type, can adopt welding method.
For reducing vibration and noise, described valve body and valve base chamber are provided with valve washer.
For improving throttling, effectiveness in vibration suppression, in the utility model, described restrictor ring adopts multi-disc disk with holes to be formed by stacking.
The utility model superiority is: can realize multistage throttle, operate steadily that noise is low, be difficult for leaking long service life.

The utility model structural profile schematic representation.
Embodiment
Shown in figure the utility model structural profile schematic representation, a kind of oils modulating valve of the utility model, comprise valve body 1 and the valve gap 2 that is installed in valve body 1 top, be located at valve body 1 and be provided with straight-through type import and export 3,3 ', the oils controlling mechanism is installed in the valve body 1, wherein, described oils controlling mechanism comprises being located at imports and exports 3, cylindrical shape valve seat 4 in 3 ', be located at the porous restrictor ring 5 that the multi-disc disk with holes of valve seat 4 tops is formed by stacking, be located at the porous current-sharing cover 6 of restrictor ring top, be provided with circular cone cylindrical valve spool 7 in the current-sharing cover 6, spool 7 tops connect valve rod 8, are provided with valve washer 9 at valve body 1 and 4 of valve seats.
In the present embodiment, move up and down the passage section that changes restrictor ring 7, guarantee the adjusting of oily flow by spool 7.By the porous restrictor ring pressure is reduced, progressively tend to balance.Reduce and to wash away chance, guarantee that oil supply system normally moves.
Spool of the present utility model moves and can use automatic operation system, and its working principle is the 24VDC signal that utilizes regulator to send here, amplifies rear driving actuator through servoamplifier, produces end thrust, drives the spool action.
