Problems solved by technology
The existing diaphragm pump oil discharge structure has the following disadvantages: 1. The guide rod is provided with an open groove, which is complicated to process. When the diaphragm is installed, there are many alignment points between the guide rod and the roller; 2. When the tail of the guide rod pushes the valve stem to move upward The force is relatively large, and the area of the opening groove connected with the guide sleeve is small and easy to be worn, and it is not good for the diaphragm supporting the guide rod; 3. When the valve core is sealed, it is subjected to the lateral force of the guide rod, and the reliability is affected influences

The invention discloses an oil discharge structure of a diaphragm pump. The oil discharge structure comprises an oil discharge valve and a guide rod; the oil discharge valve comprises a valve body, a valve rod and a valve core, wherein the valve body is provided with a valve body cavity and an oil discharge hole, the valve core and the upper portion of the valve rod are connected and are arranged in the valve body cavity, the lower portion of the valve rod is positioned on the lower side of the valve body and is provided with a rolling wheel, and the guide rod is positioned below the rolling wheel; the valve core and the valve rod are of a split structure; and the guide rod comprises a guide rod body and a guide rod tail, the upper surface of the guide rod tail is lower than the upper surface of the guide rod body, when the rolling wheel is connected with the guide rod tail, the valve rod presses the valve core downwards to open the oil discharge valve, and when the rolling wheel is connected with the guide rod body, a valve core spring pushes the valve core upwards to close the oil discharge valve. According to the oil discharge structure, the guide rod is easy to machine and is well stressed, a diaphragm supporting the guide rod is benefited, the valve core does not receive the lateral force of the guide rod when sealed, and the reliability is high.
Description
technical field [0001] The invention relates to a diaphragm pump, in particular to an oil discharge structure of the diaphragm pump. Background technique [0002] Diaphragm pump is a relatively special positive displacement pump, its structure includes working chamber, hydraulic chamber, diaphragm, plunger and power unit. The diaphragm in the diaphragm pump separates the working chamber from the hydraulic chamber. When the diaphragm pump is working, the power device drives the plunger to reciprocate. The movement of the plunger is transmitted to The diaphragm makes the diaphragm agitate back and forth, and when the diaphragm is agitated back and forth, the volume of the working chamber located on the other side of the diaphragm is changed to suck and discharge liquid. [0003] During the working process of the diaphragm pump, if the amount of oil in the hydraulic chamber is too much, it will affect the degree of deformation of the diaphragm, and even damage the diaphragm.
