Floater liquid level regulator

Abstract

The invention relates to the technical field of instruments and meters, and discloses a floater liquid level regulator which comprises a valve body. A connecting frame is fixedly connected to the topof the valve body; a flange plate is fixedly installed on the front face of the connecting frame; a connecting rod is movably connected to the front face of the flange plate; a floating ball fixedly connected to the front face of the connecting rod; a pressure regulator is fixedly installed on the back face of the connecting frame; the back face of the pressure regulator is in threaded connectionwith a screw rod; a transmission cavity is formed in the horizontal part of the connecting frame; a driven hole is formed in the vertical part of the connecting frame; a hydraulic cavity is formed inthe position, between the transmission cavity and the driven hole, in the connecting frame; a transmission rod is movably connected to the end, close to the flange plate, of the transmission cavity ina sleeving mode; a rotating cam making contact with the transmission rod is fixedly installed on the outer ring of the connecting end of the connecting rod and the flange plate; and a lever support is replaced with the connecting frame, and a conduction structure is arranged in the connecting frame, so that the stability and the precision of adjustment are guaranteed.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a float liquid level regulator. Background technique [0002] When storing oil, it is generally necessary to ensure the reserve. In order to prevent excessive storage, a protective valve structure is generally installed. The float level regulator is one of them. It uses the hollow float to float upward under the action of buoyancy to drive the lever. The connecting rod of the structure is pulled, so that the other end of the lever structure opens the valve at the bottom to release the oil stored in the oil tank to ensure that the stored amount will not exceed the calibration value. The structure and principle are simple, but it needs to be used when using Notice: [0003] 1. The float of the float level regulator is lifted by the buoyancy to drive the connecting rod to rotate up and down. In practice, when the oil is poured into the oil storage tank, it will fluct...

Problems solved by technology

[0003] 1. The float of the float level regulator is lifted by the buoyancy to drive the connecting rod to rotate up and down. In practice, when the oil is poured into the oil storage tank, it will fluctuate due to the fluidity of the fluid, which will act on the float. As a result, the float fluctuates non-stop. When the oil volume is low, only a large slosh occurs. This sway will cause the lever to rotate continuously and affect its life. At the same time, it will be intermittent when the oil volume is large. Trigger the bottom valve to open and close, resulting in intermittent oil drainage when the actual scalar volume is not reached, which cannot achieve precision control and is not conducive to oil storage;

[0004] 2. The lever structure principle adopted by the float liquid level regulator connects the float and the valve, and it is set outside the frame and not in the same plane, so that the lever transmission will cause a certain deviation, so that it is easy to drive the rod on the float It gets stuck during movement, which makes it impossible to transfer to the valve to realize oil drainage, and the effect of regulation cannot be achieved. Moreover, it is very laborious to use the method of opening the valve upward when the oil pressure is high, and it is difficult to control the size of the pressure relief.
