Problems solved by technology

At the same time, considerable damping effect is required in the safety valve to suppress the vibration of the valve core, but relatively strong damping effect will reduce the response speed of the safety valve, so the design of the damping element should take into account the response time and damping strength

Embodiment Construction

[0028] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0029] see figure 1 and figure 2 , the safety valve provided by the present invention has a 3D-printed split-flush valve sleeve. The safety valve adopts two-stage throttling, and uses a separate throttling element-splitter-hedged valve sleeve to share the pressure drop at the valve port, reducing the The pressure difference between the two ends of the valve port reduces the flow velocity of t...

Abstract

The invention belongs to the technical field related to safety valves, and discloses a safety valve with a 3D-printed diversion-hedging valve sleeve. The safety valve includes an upper valve body, a lower valve body, and a diversion-hedging valve sleeve. The upper valve The lower valve body is connected with the lower valve body, and the lower valve body is provided with a safety valve outlet and a safety valve inlet connected to each other; The inlet of the valve and the outlet of the safety valve are both connected to a diverging and hedging channel, and the diverting and hedging channel is throttling in the manner of diverting, right-angle turning and converging and hedging. The present invention arranges the diverting and flushing flow channel on the valve sleeve of the safety valve, thereby not increasing the volume of the safety valve, which has a better promoting effect on reducing the volume of the safety valve and realizing the miniaturization of the safety valve, and The safety valve shown is a safety valve that comprehensively considers flow capacity, throttling effect, overall volume, response speed and damping effect.

Description

technical field [0001] The invention belongs to the technical field related to safety valves, and more specifically relates to a safety valve with a 3D-printed split-flow and flush-type valve sleeve. Background technique [0002] The safety valve is a pressure control valve, which is normally closed. When the medium pressure in the hydraulic circuit of the test bench exceeds the limit value, the safety valve opens to discharge the medium to the outside of the system to prevent the medium pressure in the circuit from exceeding the limit value. [0003] The maximum pressure set by the safety valve and the system pipeline is controlled by the pressure regulating spring of the safety valve. When the hydraulic pressure at one end of the spool is greater than the spring force generated by the pressure regulating spring, the valve port will open, and the medium will pass through the safety valve and then part of the medium in the pipeline will be discharged from the safety valve to...
