The utility model relates to a hydraulic component technique among the hydraulic system, concretely relates to one-way choke valve.
Background
The common one-way valve is used for enabling hydraulic oil to flow only in one direction and not allowing the hydraulic oil to flow backwards in the opposite direction, the common throttling valve is used for controlling a flow control valve of fluid flow by changing a throttling section or a throttling length, and the throttling valve and the one-way valve are connected in parallel to form the one-way throttling valve.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned weak point that exists among the prior art, the utility model aims to provide a can control reverse flow backwards flow one-way throttle valve of flow size.
The utility model discloses a following technical scheme realizes: the one-way throttle valve comprises a valve seat with an oil inlet and an oil outlet, wherein a valve body is arranged in the valve seat, the oil outlet of the valve seat is provided with a spring seat connected with the oil outlet, a return spring is arranged between the spring seat and the valve body, a cavity is arranged in the valve seat, the valve body is arranged in the cavity and can slide between the oil inlet and the oil outlet, a throttling groove is formed in the valve body along the circumferential direction, a shaft hole is formed in the valve body along the axial direction, a radial hole communicated with the shaft hole is formed in the valve body along the radial direction, and a needle oil hole communicated.
Further, the front end of the valve body is in a conical shape.
Further, the spring holder is connected with the valve seat through threads.
Further, be equipped with on the spring holder with the communicating oil outlet in shaft hole.
Compared with the prior art, the utility model, following advantage and beneficial effect have: due to the structure, the valve body simultaneously realizes two functions of the check valve and the throttle valve, and has the characteristics of quick oil inlet, slow oil return, simplicity and convenience in installation, convenience in use and the like.
Drawings
Other features, objects and advantages of the invention will become more apparent upon reading of the detailed description of non-limiting embodiments with reference to the following drawings:
fig. 1 is a schematic structural view of the present invention;
wherein: 1-oil inlet, 2-oil outlet, 3-valve seat, 4-valve body, 5-spring seat, 6-return spring, 7-cavity, 8-throttling groove, 9-shaft hole, 10-radial hole, 11-needle oil hole and 12-oil outlet hole.
Detailed Description
