Pressure gauge refers to an instrument that uses elastic components as sensitive components to measure and indicate higher than ambient pressure. It is extremely common in applications. It is used in almost all industrial processes and scientific research fields. It is used in heat pipe networks, oil and gas transmission, water and gas supply systems, and vehicles. Maintenance and repair shops and other fields can be seen everywhere, especially in the industrial process control and technical measurement process, because the elastic sensitive element of the mechanical pressure gauge has high mechanical strength and convenient production, the mechanical pressure gauge is getting more and more Widely used.
In the pipeline of the processing workshop of the chemical plant, a diaphragm pressure gauge needs to be installed to facilitate the measurement of the pressure value. At present, the existing diaphragm pressure gauge does not have the function of preventing strong corrosion. Because the chemical plant will use it in the process of processing If the liquid with strong corrosion is easy to splash on the diaphragm pressure gauge, it will corrode the diaphragm pressure gauge. Once the diaphragm pressure gauge is corroded, it will cause an error in the measurement and may cause damage to the diaphragm pressure gauge, thereby reducing the diaphragm The practicality of the pressure gauge.
In view of the shortcomings of the prior art, the present invention provides an anti-corrosion diaphragm pressure gauge, which has the advantages of anti-corrosion, and solves the problem that the existing diaphragm pressure gauge does not have an anti-corrosion function.
In order to achieve the above object, the technical solution provided by the present invention is: an anti-corrosion diaphragm pressure gauge, including a pressure gauge case, a rotary shaft movably connected to a center of the front surface of the pressure gauge case, and a fixed surface of the rotary shaft The pointer, the front surface of the pressure gauge case is provided with a scale, the bottom of the pressure gauge case is fixedly connected with the instrument seat, the bottom of the surface of the instrument seat is fixedly connected with the flange seat; the top of both sides of the instrument seat are fixedly connected with the bearing plate , The top of the bearing plate is movably connected to the protective box, the bottom of the inner wall of the protective box is fixedly connected to the fixed block, the bottom of the bearing plate is provided with screws, the top of the screw penetrates to the top of the fixed block, the top of the screw surface is threaded The surface of the nut and 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, 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 a paint layer is fixedly connected on the surface of the asphalt paint layer.
The inner wall of the graphite layer and the surface of the strong pressure layer are fixedly connected by viscose. The surface of the graphite layer and the inner wall of the resin paint layer are fixedly connected by viscose. The surface of the resin paint layer and the inner wall of the asphalt paint layer are fixedly connected by viscose. The surface of the asphalt paint layer and the inner wall of the paint layer are fixedly connected by viscose. The material of the strong pressure layer is steel, and the inner wall of the strong pressure layer is welded to the surface of the protective box. The surface of the screw is fixedly connected with thread one, and the inner wall of the nut is fixedly connected with thread two used in conjunction with thread one. The bottom of the bearing plate is provided with a through slot for use with screws, and the bottom of the fixing block is provided with a through slot for use with screws.
Compared with the prior art, the present invention provides a strong anti-corrosion diaphragm pressure gauge, which has the following beneficial effects: 1. The present invention provides a bearing plate, a protective box, a fixed block, screws, nuts, a strong pressure-resistant layer, Corrosion layer, graphite layer, resin coating layer, asphalt paint layer and paint layer cooperate with each other to achieve the effect of preventing strong corrosion, which solves the problem that the existing diaphragm pressure gauge does not have the function of preventing strong corrosion, so that the diaphragm pressure gauge will not Corrosion occurs, which ensures the accuracy of the measured values, reduces the damage rate of the diaphragm pressure gauge, and thus improves the practicality of the diaphragm pressure gauge. 2. The present invention protects the diaphragm pressure gauge by providing 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. It solves the problem of the protective box falling off during use. By setting a strong pressure-resistant layer, it plays a role in withstanding the pressure of the protective box, and solves the problem that the protective box is damaged due to excessive pressure during use. The anti-corrosion layer is provided to prevent the diaphragm pressure gauge from corrosion, which solves the problem that the diaphragm pressure gauge is corroded during use, causing the diaphragm pressure gauge to be damaged.
