Abstract
The invention discloses a low-pressure belt gas rotating seal structure which comprises a fixed round cap that is provided with a fixed circular plate; the fixed circular plate is fixed on a table; the lower end of the fixed round cap is provided with a fixed core shaft sleeve; a fixed core cap is arranged outside the fixed core shaft sleeve; and an O-shaped ring is arranged in the fixed core shaft sleeve. The O-shaped ring is arranged in the fixed core shaft sleeve, so that the tightness of a gas circuit is improved, and the pressure measurement accuracy is improved.
Description
Technical field
The present invention relates to a kind of depression belt cyclone and turn sealing configuration.
Background technique
Pressure gauge is take elastic element as sensing element, measures and indicate the instrument that is higher than external pressure.Pressure gauge conducts to pointer by the switching mechanism of showing interior movement with pressure deformation by the elastic strain of the sensing element (such as Bourdon tube, bellows, bellows etc.) in the table, causes that pointer rotates to show pressure.Manometric application is very general, almost spreads all over all industrial flows and scientific research field, and in heat distribution pipe network, oil gas transmission, water and air supply system, vehicle maintenance maintenance factory shop, pressure gauge is used and is seen everywhere.
In the prior art, the gas circuit between manometric sensing element and the movement is easily leaked gas, and causes pressure measurement inaccurate, demands urgently improving.
Summary of the invention
Problem for prior art exists the object of the invention is to propose a kind of depression belt cyclone and turns sealing configuration, by enforcement of the present invention, prevents pressure gauge gas leakage, improves accuracy of measurement.
For reaching this purpose, the present invention by the following technical solutions:
A kind of depression belt cyclone turns sealing configuration, comprising:
Fixing circle cap has fixed disc, and described fixed disc is fixing on the table, and described fixing round cap lower end is provided with centering spindle's cover, and described centering spindle outer being equipped with of cover decided the core cap, is provided with O type circle in the described centering spindle cover.
Preferably, described fixed disc is fixing on the table by socket head screw.
Preferably, outer being equipped with by socket head screw of described centering spindle's cover decided the core cap.
Based on disclosing of above technological scheme, the present invention possesses following beneficial effect:
The present invention by be provided with O type circle in centering spindle's cover, has increased the sealing of gas circuit, has improved pressure measurement accuracy.
Description of drawings
Fig. 1 is that a kind of depression belt cyclone of the embodiment of the invention 1 turns sealed structure chart.
Reference character:
6, angle thrust axis bearing sleeve; 9, socket head screw; 10, round pin; 11, socket head screw; 12,13, O type circle; 18, antislip ring; 19, round nut; 20, fixed disc; 21, fixing circle cap; 22, centering spindle's cover; 23, decide the core cap; 30, desktop; 100, the depression belt cyclone turns sealing configuration.
Embodiment
The embodiment of the invention 1 provides a kind of depression belt cyclone to turn sealing configuration 100, be used for axis body bar section outside sheathed angle thrust axis bearing sleeve 6 and desktop 30 be tightly connected, the bar section of axis body is equipped with antislip ring 18 away from an end of head by round nut 19 and round pin 10, as shown in Figure 1.Wherein, fixing circle cap 21 has fixed disc 20, can be fixed on the desktop 30 by socket head screw 9; Fixing circle cap 21 lower ends are provided with centering spindle's cover 22, and centering spindle's cover 22 outer being equipped with by socket head screw 11 are decided core cap 23; Be provided with O type circle 12,13 in centering spindle's cover 22, be used for sealing.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technological scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
Claims (3)
1. a depression belt cyclone turns sealing configuration, it is characterized in that, comprising:
