Abstract
The invention discloses a one-way valve structure for a hydraulic system of a wind power generating set. The one-way valve structure comprises a valve base and a valve core, wherein one end of the valve core is a frustum structure shape; a spring is sleeved on the valve core; the valve base includes an inlet and an outlet; an oil channel is arranged between the inlet and the outlet, and a port which is in contact with the end of the frustum structure shape of the valve core is arranged on the oil channel; the valve core can move in a bushing arranged on the valve base; a port on the oil channel of the valve base is in a hollow frustum structure; and the hollow frustum structure is matched with the frustum structure shape at one end of the valve core, which is in contact with the hollow frustum structure. According to the one-way valve structure disclosed by the invention, the zero leakage can be kept under the condition of long-term operation, and thus the stability of the hydraulic system is ensured.
Description
Technical field
The present invention and a kind of wind power generating set hydraulic system check valve structure.
Background technique
Hydraulic system in the wind power generating set, it is mainly used in the control in the states such as adjusting vane pitch, damping, shutdown, brake.The leakage of hydraulic system components and parts directly affects the stability of hydraulic system pressure, thereby affects the Security and the reliability of wind power generating set system works.Contain the plurality of valves class in the hydraulic system, as one-way valve, this valve contains valve seat and spool, and valve seat contains import and outlet, is provided with oily passage between import and outlet.Move in the sleeve pipe that spool can be provided with on valve seat, an end of spool is a platform cone structure shape, and valve core upper sleeve is equipped with spring.Oily passage in the valve seat is provided with and the contacted port of spool platform cone structure this end of shape, the angle that forms between the end face of this port and the inwall of oily passage is the right angle, contacting between therefore above-mentioned valve seat oil access port and this end of spool platform cone structure shape is that line contacts, thereby sealing range is little, and the leakage probability is big.Simultaneously since each need of work contact-impact once, even therefore material surface is handled, but under the situation of long-term work, its line contacting point will heavy wear and produce leakage, this has influenced the stability of hydraulic system.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of wind power generating set hydraulic system check valve structure, and this check valve structure can keep zero leakage under the situation of long-term work.
For solving the problems of the technologies described above, a kind of wind power generating set hydraulic system check valve structure provided by the invention, it contains valve seat, spool, one end of spool is a platform cone structure shape, valve core upper sleeve is equipped with spring, valve seat contains import and outlet, between import and outlet, be provided with oily passage, this oil passage is provided with and the contacted port of spool platform cone structure this end of shape, move in the sleeve pipe that spool can be provided with on valve seat, the port that described valve seat oil passage is provided with is the platform cone structure of interior sky, and platform cone structure and contacted with it cone structure shape of spool one end empty in this are suitable.
Because the port that valve seat oil passage is provided with is the platform cone structure of interior sky, platform cone structure and contacted with it cone structure shape of spool one end empty in being somebody's turn to do are suitable, the port that is provided with of valve seat oil passage is that face contacts with contacting of this end of spool platform cone structure shape like this, from the face contact seal after improve of the line contact sealing of prior art, not only overcome prior art and touched the deficiency that wearing and tearing comparatively fast produce leakage because of wiring, even and wearing and tearing under the situation of long-term work, also be synchronous wearing and tearing, be the surface wearing and tearing synchronously of surface and contacted with it cone structure shape of spool one end of platform cone structure of the interior sky of valve seat oil access port, so can realize zero leakage.
Description of drawings
Fig. 1 is the schematic representation of a kind of wind power generating set hydraulic system of the present invention with check valve structure.
1. oily passages among the figure, 2. port, a 3. cone, 4. spring, 5. valve seat, 6. sleeve pipe, 7. spool, 8. outlet, 9. import.
Embodiment
Among Fig. 1, a kind of wind power generating set hydraulic system check valve structure, it contains valve seat 5, spool 7.One end of spool 7 is platform cone 3 structure shapes, is set with spring 4 on the spool 7.Valve seat 5 contains import 9 and outlet 8, is provided with oily passage 1 in import 9 with between exporting 8, and this oil passage 1 is provided with the contacted port 2 of this end of platform cone 3 structure shapes with spool 7.Move in the sleeve pipe 6 that spool 7 can be provided with on valve seat 5.The port 2 that the oily passage 1 of valve seat 5 is provided with is the platform cone structure of interior sky, and structure shape of the platform cone structure of sky and the contacted with it cone 3 of spool 7 one ends is suitable in this.The platform cone structure of sky in the port 2 that the present invention is provided with owing to the oily passage 1 with valve seat 5 is made into, the structure shape of the platform cone structure of sky and the contacted with it cone 3 of spool 7 one ends is suitable in being somebody's turn to do, the port 2 that is provided with of the oily passage 1 of valve seat 5 is the face contact with the contacting of platform cone 3 of spool 7 like this, therefore from the face contact seal after improve of the line contact sealing of prior art, not only overcome prior art and touched the deficiency that wearing and tearing comparatively fast produce leakage because of wiring, even and wearing and tearing under the situation of long-term work, also be synchronous wearing and tearing, be the surface of platform cone structure of interior sky of port 2 of valve seat 5 oily passages 1 and the surface wearing and tearing synchronously of contacted with it cone structure shape of spool 7 one ends, thereby can realize zero leakage, to guarantee the stability of hydraulic system.
Claims (1)
1. wind power generating set hydraulic system check valve structure, it contains valve seat, spool, one end of spool is a platform cone structure shape, valve core upper sleeve is equipped with spring, valve seat contains import and outlet, between import and outlet, be provided with oily passage, this oil passage is provided with and the contacted port of spool platform cone structure this end of shape, move in the sleeve pipe that spool can be provided with on valve seat, it is characterized in that: the port that described valve seat oil passage is provided with is the platform cone structure of interior sky, and platform cone structure and contacted with it cone structure shape of spool one end empty in this are suitable.
