Embodiment Construction
[0014] see figure 1 , figure 2 The anti-transport pointer pressure gauge of the present invention includes a housing 1 and a base 2 arranged in the housing, a movement 3, a Baden tube 4, a temperature compensation plate 5, an end seat 6, a pointer 7, a dial 8, a seal Screw 9, sealing gasket 10, external joint group 11, Baden tube protection piece 12, watch cover sealing ring, watch cover, watch glass. Wherein, the watch cover sealing ring and the watch glass are respectively fixed on the casing 1 with the watch cover. The sealing gasket 10 is fixed on the air sealing hole of the housing 1 with the sealing screw 9 . The movement 3 is fixed on the base 2, and the pointer 7 and the dial group 8 are respectively fixed on the movement 3. One end of the Baden tube 4 is welded on the base 2 and communicated with it, the other end is welded together with the end seat 6, the end seat 6 is connected with one end of the temperature compensation sheet 5, and the other end of the tempe...

The invention provides a pointer type pressure gauge resisting transport shocks. The pointer type pressure gauge resisting the transport shocks comprises a shell, a base, a movement, a Burdon tube, an end base, a pointer, a dial assembly, a gauge cover seal ring and a gauge cover, wherein the base, the movement, the Burdon tube, the end base, the pointer, the dial assembly, the gauge cover seal ring and the gauge cover are arranged in the shell. Due to the facts that a Burdon tube protecting part is added, and the Burdon tube protecting part plays a role in protecting the Burdon tube, the transport shock resisting capacity of the pointer type pressure gauge can be greatly improved. According to the pointer type SF6 gas pressure gauge resisting the transport shocks, the protection effect on the Burdon tube is achieved, the transport shock resisting capacity of the pointer type SF6 gas pressure gauge can be improved during transport.
Description
technical field [0001] The invention relates to a pressure gauge, in particular to a pointer pressure gauge. Background technique [0002] SF 6 Electrical products have been widely used in the power sector, industrial and mining enterprises, and promoted the rapid development of the power industry. Guaranteed SF 6 The reliable and safe operation of electrical products has become one of the important tasks of the power sector. SF 6 The arc extinguishing medium and insulating medium of electrical products are SF 6 Gas, no air leakage can occur, if there is an air leakage, the SF cannot be guaranteed 6 Electrical products operate reliably and safely. So monitor SF 6 SF for electrical products 6 The density value is very necessary. Now used to monitor SF 6 Density generally adopts a mechanical pointer density gauge (or pressure gauge), with when SF 6 When an electrical product leaks, the density value can be displayed on the spot. [0003] At present, these densi...
