Embodiment Construction

[0050] The present invention will be further described below in conjunction with accompanying drawing.

[0051] like Figure 1~4 As shown, the two-way ratchet hydraulic actuator 2 is characterized in that it includes a frame 21, on which a ratchet assembly 22 is rotatably connected, and the ratchet assembly 22 includes a forward ratchet 23 and a reverse ratchet 24 coaxially arranged. , the forward ratchet 23 and the reverse ratchet 24 are connected through mutual tenons, and the ratchet assembly 22 is provided with a concentric cylinder (that is, the three are coaxial) between the forward ratchet 23 and the reverse ratchet 24, and the outer circumference of the concentric cylinder is set A rotating arm 25 is provided, and the upper and lower surfaces of the rotating arm 25 are respectively hingedly provided with ratchets 26, wherein one ratchet 26 is matched with the ratchet teeth of the forward ratchet 23, and the other ratchet 26 is connected with the reverse ratchet. The r...

Abstract

The invention relates to a hydraulic actuator with bidirectional ratchet wheels and a safety valve calibrating device. The hydraulic actuator with the bidirectional ratchet wheels comprises a framework. A ratchet wheel assembly is arranged on the framework in a rotationally connected manner and comprises the forward ratchet wheel and the reverse ratchet wheel, the forward ratchet wheel and the reverse ratchet wheel are coaxially arranged and are connected with each other by respective matched rabbets, a rotary arm sleeves the periphery of a concentric cylinder arranged in the middle of the ratchet wheel assembly, pawls are respectively arranged on the upper surface and the lower surface of the rotary arm in a hinged manner, one of the pawls is matched with teeth of the forward ratchet wheel, the other pawl is matched with teeth of the reverse ratchet wheel, the two pawls are provided with reversing driving mechanisms, power hydraulic cylinders for driving the rotary arm to rotate are respectively hinged to two sides of the rotary arm, the other ends of the two power hydraulic cylinders are connected to two sides of the framework, and working holes are formed in the ratchet wheel assembly along the axial direction of the ratchet wheel assembly and are through holes. The hydraulic actuator and the safety valve calibrating device have the advantage that safety valves can be automatically calibrated by the aid of the integral safety valve calibrating device.

Description

technical field [0001] The invention relates to a bidirectional ratchet hydraulic actuator and a safety valve verification device, which belong to the technical field of safety valve verification and the field of hydraulic pressure. Background technique [0002] The safety valve is a special valve whose opening and closing parts are in a normally closed state under the action of external force. When the medium pressure in the equipment or pipeline rises above the specified value, it discharges the medium to the outside of the system to prevent the medium pressure in the pipeline or equipment from exceeding the specified value. . Safety valves are automatic valves, mainly used in boilers, pressure vessels and pipelines, to control the pressure not to exceed the specified value, and play an important role in protecting personal safety and equipment operation. Safety valve is a special equipment. The safety valve must pass a pressure test (that is, calibration, colloquially c...
