Today, I will introduce a national invention authorized patent-an anti-corrosion diaphragm pressure gauge. The patent was applied for by Wuxi Kaifeng Pressure Gauge Co., Ltd., and the authorization was announced on December 8, 2017.
Content descriptionThe invention relates to the technical field of pressure gauges, in particular to an anti-corrosion diaphragm pressure gauge.
Background of the inventionPressure gauge refers to an instrument that uses elastic components as sensitive components to measure and indicate pressure higher than the ambient pressure. It is widely used. It covers almost all industrial processes and scientific research fields, in heating pipe networks, oil and gas transmission, water and gas supply systems, and vehicles. Repair and maintenance factories and shops can be seen everywhere, especially in the process of industrial process control and technical measurement. Because the elastic sensitive elements of mechanical pressure gauges have high mechanical strength and convenient production characteristics, mechanical pressure gauges have become more and more popular. Wide range of applications.
Diaphragm pressure gauges need to be installed on the pipelines in the processing workshops of chemical plants to facilitate use when measuring pressure values. The existing diaphragm pressure gauges do not have the function of anti-corrosion, because chemical plants will use them during processing. The strong corrosive liquid is easy to splash on the diaphragm pressure gauge, which will corrode the diaphragm pressure gauge. Once the diaphragm pressure gauge is corroded, it will cause measurement errors, which may cause the diaphragm pressure gauge to be damaged, thereby reducing the diaphragm. The practicality of the pressure gauge.
Summary of the inventionIn view of the shortcomings of the prior art, the present invention provides an anti-corrosion diaphragm pressure gauge, which has the advantage of anti-corrosion, and solves the problem that the existing diaphragm pressure gauge does not have the function of anti-corrosion.
In order to achieve the above-mentioned object, the technical solution provided by the present invention is: an anti-corrosion diaphragm pressure gauge, comprising a pressure gauge case, the axis of the front surface of the pressure gauge case is movably connected with a rotating shaft, and the surface of the rotating shaft is fixedly connected with Pointer, the front surface of the pressure gauge case is provided with a scale gauge, the bottom of the pressure gauge case is fixedly connected with an instrument seat, and the bottom of the surface of the instrument seat is fixedly connected with a flange seat; the tops of both sides of the instrument seat are fixedly connected with a bearing plate , The top of the load-bearing board is movably connected with a protective box, the bottoms on both sides of the inner wall of the protective box are fixedly connected with fixed blocks, the bottom of the load-bearing board is provided with screws, the top of the screws penetrates to the top of the fixed block, and the top of the screw surface is threaded with Nut, the surface of the protective box is fixedly connected with a strong pressure-resistant layer, and the surface of the strong pressure-resistant layer is fixedly connected with an anti-corrosion layer; the anti-corrosion layer includes a graphite layer, and the surface of the graphite layer is fixedly connected with a resin coating layer, and the surface of the resin coating layer An asphalt paint layer is fixedly connected, and the surface of the asphalt paint layer is fixedly connected with a paint layer.
The inner wall of the graphite layer and the surface of the strong pressure-resistant layer are fixedly connected by glue, the surface of the graphite layer and the inner wall of the resin coating layer are fixedly connected by glue, and the surface of the resin coating layer and the inner wall of the asphalt paint layer are fixedly connected by glue. The surface of the asphalt paint layer and the inner wall of the paint layer are fixedly connected by glue. The material of the strong pressure-resistant layer is steel, and the inner wall of the strong pressure-resistant layer is welded to the surface of the protective box. The surface of the screw is fixedly connected with the first thread, and the inner wall of the nut is fixedly connected with the second thread used in cooperation with the first thread. The bottom of the bearing plate is provided with a through slot 1 for use with screws, and the bottom of the fixing block is provided with a through slot 2 for use with screws.
Compared with the prior art, the present invention provides an anti-corrosion diaphragm pressure gauge, which has the following beneficial effects: 1. The present invention provides a load-bearing plate, a protective box, a fixing block, screws, nuts, a strong pressure-resistant layer, and a Corrosion layer, graphite layer, resin coating layer, asphalt paint layer and paint layer cooperate with each other to achieve the effect of anti-corrosion, and solve the problem that the existing diaphragm pressure gauge does not have the function of anti-corrosion, so that the diaphragm pressure gauge will not The occurrence of corrosion ensures the accuracy of the measured values ​​and reduces the damage rate of the diaphragm pressure gauge, thereby improving the practicability of the diaphragm pressure gauge. 2. The present invention protects the diaphragm pressure gauge by installing a protective box, and solves the problem of corrosion of the diaphragm pressure gauge caused by long-term use of the diaphragm pressure gauge. By setting screws and nuts, the protective box is fixed. The problem of the protective box falling off during use is solved. By setting a strong pressure-resistant layer, the protective box can withstand pressure, and the problem of damage to the protective box due to excessive pressure during use is solved. The anti-corrosion layer is provided to prevent corrosion of the diaphragm pressure gauge, and solve the problem of the diaphragm pressure gauge being corroded during use and causing damage to the diaphragm pressure gauge.
