Abstract
The utility model relates to hydraulic throttle valves, in particular to an improved axial flow hydraulic throttle valve, and belongs to the technical field of hydraulic pressure. The throttle valve comprises an adjustable valve element with an outer knuckle thread structure, a valve seat is arranged outside the adjustable valve element, the valve seat is provided with inner knuckle threads matched with the adjustable valve element, and axial guide grooves are evenly formed in the adjustable valve element. Due to the axial self-locking property of a screw thread pair, the axial displacement of the adjustable valve element is controlled in the left-right direction, the size of the radial opening, at the position the axial guide grooves are evenly formed, of the adjustable valve element is made to be changed accordingly, and proper flow output is obtained from the right end of the valve seat.
Description
Technical field
The utility model relates to a kind of hydraulic throttle valve, is specifically related to a kind of improved axis to a fluid stream hydraulic throttle valve, belongs to the hydraulics field.
Background technique
The hydraulic flow throttle valve is the key element in hydraulic system, and due to its accurate internal structure and changeable dynamic operation condition, therefore keeping hydraulic fluid flow rate unobstructed and stable is the key of throttle valve efficiency.Be subject to the combined influence of the uncertain factors such as pressure reduction in hydraulic system, oil temperature and impurity, the project organization of restriction has determined the stability of the anti-interference rate of discharge of throttle valve.
Summary of the invention
The purpose of this utility model provides a kind of improved axis to a fluid stream hydraulic throttle valve for overcoming above-mentioned the deficiencies in the prior art part, under the precondition of existing process equipment, and the structure shape of refinement flow throttle valve key position.Balance influence throttle flow rate stable structure key element, the concrete design consideration such as comprehensive pressure reduction, oil temperature, liquid resistance and unimpeded are intended to obtain stability on the basis of original throttle valve regulating flow and promote.The utility model promotes the stability of output flow by means of many advanced accurate process equipment and process means with small geometry groove and curved-surface structure.
The utility model is realized with following technological scheme: a kind of improved axis is characterized in that to a fluid stream hydraulic throttle valve: this throttle valve includes the adjustable valve core of cylindrical worm structure, and adjustable spool outside is valve seat.
The interior round thread that is complementary with the adjustable valve core is arranged on described valve seat.
Be evenly equipped with the axial diversion groove on described adjustable valve core.
The utility model has the advantages that: this throttle valve has the throttling adjustable spool of cylindrical worm structure, and valve seat is provided with the interior round thread that is complementary with the adjustable valve core.Due to the axial self-locking of screw pair, the left and right axial displacement of regulation and control throttling valve core correspondingly changes its radial opening size at axial uniform straight trough, obtains suitable flow output with this right-hand member at valve seat.
Description of drawings
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail:
Fig. 1 is the utility model structural representation;
Fig. 2 is Fig. 1 left view;
In figure: 1, adjustable valve core, 2, valve seat, 3, the axial diversion groove.
Embodiment
As shown in the figure: a kind of improved axis is to a fluid stream hydraulic throttle valve, and this throttle valve includes the adjustable valve core 1 of cylindrical worm structure, and adjustable spool outside is valve seat 2.
The interior round thread that is complementary with adjustable valve core 1 is arranged on described valve seat 2.
Be evenly equipped with axial diversion groove 3 on described adjustable valve core.
Claims (3)
