Abstract
The invention discloses a diaphragm-seal pressure gauge. The diaphragm-seal pressure gauge comprises an adjusting screw, a sealing ring, a gear, pins and an adjustable panel, wherein the adjusting screw passes through the sealing ring and the gear and then is connected with the adjustable panel; and the pins are inserted into the gear and the adjusting screw. According to the diaphragm-seal pressure gauge, an indicator can be conveniently and quickly adjusted to reach a zero position by the adjusting screw outside a housing.
Description
Technical field
The present invention relates to a kind of tensimeter, particularly a kind of diaphragm.
Background technology
During existing manometric pointer generation deviation, the user is only opening in the situation of shell, just can revise zero-bit, troublesome poeration by adjusting with the adjusting gear of zeroing pointer functionality.
Summary of the invention
Technical matters to be solved by this invention provides a kind of diaphragm, and its adjusting screw(rod) by housing exterior is just adjusted the pointer zero-bit easily, rapidly.
For solveing the technical problem, the invention 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 described adjusting screw(rod) is yi word pattern, the O type that is shaped as of O-ring seal.
Positive progressive effect of the present invention is: the present invention just adjusts the pointer zero-bit easily, rapidly by the adjusting screw(rod) of housing exterior.
Description of drawings
Fig. 1 is the decomposition texture synoptic diagram of diaphragm of the present invention.
Fig. 2 is the structural representation after the diaphragm assembling of the present invention.
Fig. 3 is the principle of work synoptic diagram of diaphragm of the present invention.
Embodiment
The below lifts a preferred embodiment, and comes by reference to the accompanying drawings the clearer the present invention that intactly illustrates.
Such as Fig. 1, Fig. 2 and shown in Figure 3, diaphragm of the present invention comprises adjusting screw(rod) 1, O-ring seal 2, gear 3, pin 4, adjustable panel 5, and adjusting screw(rod) 1 is connected with adjustable panel 5 after passing O-ring seal 2, gear 3, and pin 4 inserts in gear 3 and the adjusting screw(rod) 1.The end shape of adjusting screw(rod) 1 is yi word pattern.The O type that is shaped as of O-ring seal 2.
Diaphragm pressure gage is by the elastic deformation of the 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.But diaphragm is under the condition of high temperature, there is hot temperature drift in the medium of hydraulic transmission device under the condition of high temperature, cause the pointer indication not in the zero-bit position, thereby the adjusting screw(rod) rotation drives the gear that is connected with adjusting screw(rod), the gear driven adjustable panel, can return to zero easily and fast like this and revise zero-bit Times is poor, show that force value is truer and more accurate, and not need to open the element such as shell.
Although more than described the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, under the prerequisite that does not deviate from principle of the present invention and essence, can make various changes or modifications to these embodiments.Therefore, protection scope of the present invention is limited by 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 described adjusting screw(rod) is yi word pattern, the O type that is shaped as of O-ring seal.
