Abstract
The utility model discloses a diaphragm pressure gauge. The diaphragm pressure gauge comprises an adjusting screw rod, a seal ring, a gear, a pin and an adjustable panel, wherein the adjusting screw rod is connected with the adjustable panel after penetrating the seal ring and the gear; and the pin is inserted into the gear and the adjusting screw rod. By adopting the diaphragm pressure gauge, the pointer can be conveniently and quickly adjusted to the zero position through the adjusting screw rod outside the casing.
Description
Technical field
The utility model relates to a kind of tensimeter, particularly a kind of diaphragm.
Background technology
During existing manometric pointer generation deviation, the user is only opening under the situation of shell, and the adjusting gear that has the pointer functionality that returns to zero through adjustment just can be revised zero-bit, troublesome poeration.
The utility model content
The utility model technical matters to be solved provides a kind of diaphragm, and its adjusting screw(rod) through housing exterior is just adjusted the pointer zero-bit easily, apace.
For solveing the technical problem; The utility model provides a kind of diaphragm, it is characterized in that, it comprises adjusting screw(rod), O-ring seal, gear, pin, adjustable panel; Adjusting screw(rod) is connected with adjustable panel after passing O-ring seal, gear, and pin inserts in gear and the adjusting screw(rod).
Preferably, the end shape of said adjusting screw(rod) is a yi word pattern, the O type that is shaped as of O-ring seal.
The positive progressive effect of the utility model is: the utility model is just adjusted the pointer zero-bit easily, apace through the adjusting screw(rod) of housing exterior.
Description of drawings
Fig. 1 is the decomposition texture synoptic diagram of the utility model diaphragm.
Fig. 2 is the structural representation after the utility model diaphragm assembling.
Fig. 3 is the principle of work synoptic diagram of the utility model diaphragm.
Embodiment
Lift a preferred embodiment below, and combine accompanying drawing to come the clearer the utility model of intactly explaining.
Like Fig. 1, Fig. 2 and shown in Figure 3; The utility model diaphragm comprises adjusting screw(rod) 1, O-ring seal 2, gear 3, pin 4, adjustable panel 5; Adjusting screw(rod) 1 passes O-ring seal 2, gear 3 backs are connected with adjustable panel 5, and pin 4 inserts in gear 3 and the adjusting screw(rod) 1.The end shape of adjusting screw(rod) 1 is a yi word pattern.The O type that is shaped as of O-ring seal 2.
Diaphragm pressure gage is through the elastic deformation of corrugated tube in the table, and the throw-over gear by movement in the table conducts to pointer with pressure deformation again, causes that pointer rotates to show pressure.However, under high temperature diaphragm pressure gauges, hydraulic transmission device exists under high temperature medium heat temperature drift, resulting pointer is not null position, adjust the screw rotation so as to drive gear connected with the adjusting screw, gear driven adjustable panels, so can be easily and quickly to zero over zero difference correction, display pressure values more real and more accurate, but no need to open the housing and other components.
Though more than described the embodiment of the utility model; But those skilled in the art is to be understood that; These only illustrate, and under the prerequisite of principle that does not deviate from the utility model and essence, can make numerous variations or modification to these embodiments.Therefore, the protection domain of the utility model is limited appended claims.
Claims (2)
1. a diaphragm is characterized in that, it comprises adjusting screw(rod), O-ring seal, gear, pin, adjustable panel, and adjusting screw(rod) is connected with adjustable panel after passing O-ring seal, gear, and pin inserts in gear and the adjusting screw(rod).
2. diaphragm as claimed in claim 1 is characterized in that, the end shape of said adjusting screw(rod) is a yi word pattern, the O type that is shaped as of O-ring seal.
