Abstract
The utility model relates to a pressure gauge. The pressure gauge comprises a plastic bottom casing. The plastic bottom casing is connected with a copper joint arranged in the plastic bottom casing through a screw thread. A seal pad is arranged on the joint between the plastic bottom casing and the copper joint. A seal plug is arranged on the joint between an air vent and the plastic bottom casing. According to the utility model, the plastic bottom casing is connected with the copper joint, thus the copper consumption is reduced, and the production cost of the pressure gauge is reduced; the seal pad is arranged on the joint between the plastic bottom casing and the copper joint, and the seal plug is arranged on the joint between the air vent and the plastic bottom casing, thus the air permeability performance of the pressure gauge is ensured, and the measurement accuracy of the pressure gauge provided by the utility model is improved.
Description
Technical field
The utility model relates to a kind of tensimeter, belongs to pressure device technical field.
Background technology
Traditional tensimeter mostly adopts copper sleeve or stainless joint, expends more metal material, and cost is higher; Simultaneously traditional its air-tightness of tensimeter is not good, is easy to generate gas leakage, causes the gauge measurement result inaccurate, influences the erroneous judgement of operating personnel to measurand pressure.
The utility model content
The utility model is to above-mentioned defective, and purpose is to provide the tensimeter that a kind of cost is low, air-tightness is good.
The technical scheme of the utility model employing is for this reason: the utility model comprises the plastics drain pan, and the plastics drain pan is arranged on the copper sleeve in the plastics drain pan through being threaded, and the joint of plastics drain pan and copper sleeve is established sealing gasket; The junction surface of air hole and plastics drain pan is provided with seal plug.
The utility model has the advantages that: the utility model plastics drain pan is connected with copper sleeve, has reduced the consumption of copper, has reduced manometric production cost; The utility model is established sealing gasket at the joint of plastics drain pan and copper sleeve in addition; The junction surface of air hole and plastics drain pan is provided with seal plug, has guaranteed the air-tightness of the utility model, has improved the accuracy of the utility model gauge measurement.
