Abstract
A novel pressure meter comprises an outer cavity, an inner cavity and a machine core. An upper connecting body and a lower connecting body are combined to form a cavity in the inside, the cavity is separated into the outer cavity and the inner cavity by a diaphragm, a bellow is arranged above the inner cavity, the diaphragm is connected with the lower end of a transmission rod, and the other end of the transmission rod vertically upwards penetrates through the bellow to be connected with the machine core. The novel pressure meter has the advantages of having accurate structure, improving accuracy, timely monitoring absolute pressure and the like. When an outer cavity of an absolute pressure meter is vacuumized (negative pressure), and an upper limit of the absolute pressure meter is reached, negative pressure of an inner cavity is larger than that of the outer cavity, and a pointer stops at the upper limit position. When the negative pressure of the outer cavity is larger than that of the inner cavity, the diaphragm shifts downwards and drives fan teeth of the machine core through the transmission rod, the pointer deflects, and the aim of measuring the absolute pressure is achieved.
Description
Technical field
The utility model relates to a kind of instrument that is used to monitor or measure the absolute pressure of some vacuum equipment, relates in particular to a kind of novel pressure table.
Background technology
The absolute pressure table is mainly used in the instrument that monitors or measure absolute pressure in some vacuum equipment (as the equipment of vacuum packaging mechanical, monitoring condensing pressure and liquid vapor pressure etc.), and absolute pressure is meant with absolute pressure zero-bit (complete vacuum) and makes benchmark, is higher than the pressure of absolute pressure zero-bit.Existing similar technology is difficult to the standard that reaches higher, and measuring accuracy is often wrong, more can't monitor absolute pressure in real time.
The utility model content
At above defective, the purpose of this utility model provides a kind of novel pressure table of improving measuring accuracy, precise structure, can monitoring absolute pressure in real time of helping, to solve many deficiencies of prior art.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of novel pressure table comprises exocoel, inner chamber and movement, and described upward connector is connected with following connector and forms a cavity in inside, and this cavity is divided into exocoel and inner chamber by diaphragm, and corrugated tube is installed in the inner chamber top; Described diaphragm connects transmission bar lower end, and this transmission bar other end passes corrugated tube straight up and is connected with movement.
The beneficial effect of novel pressure table described in the utility model is: have precise structure, can improve precision, can monitor characteristics such as absolute pressure in real time; Form a vacuum chamber by diaphragm, last connector and corrugated tube, is evacuated to different vacuum tightness (being negative pressure) by the different range of instrument in this vacuum chamber, exocoel is made up of diaphragm and following connector, and by straight-through atmosphere of joint or vacuum pump; When absolute pressure off-balancesheet chamber is vacuumized (negative pressure), before the upper limit that is evacuated to the absolute pressure table, because the negative pressure of inner chamber is greater than the exocoel negative pressure, pointer should stop upper limit position, when having only the exocoel negative pressure greater than the inner chamber negative pressure, diaphragm then is subjected to displacement downwards, and fans tooth by transmitting on the bar drive movement, pointer is deflected, to reach the purpose of measuring absolute pressure.
Description of drawings
According to embodiment and accompanying drawing the utility model is described in further detail below.
Fig. 1 is the described novel pressure list structure of a utility model embodiment synoptic diagram.
Among the figure:
1, exocoel; 2, inner chamber; 3, go up connector; 4, following connector; 5, diaphragm; 6, corrugated tube; 7, transmit bar; 8, movement.
Embodiment
As shown in Figure 1, novel pressure table described in the utility model comprises exocoel 1, inner chamber 2 and movement 8, describedly goes up that connector 3 is connected with following connector 4 and in cavity of inside formation, it is exocoel 1 and inner chamber 2 that this cavity is divided into two chambers by diaphragm 5, and corrugated tube 6 is installed in these inner chamber 2 tops; Diaphragm 5 wherein, last connector 3 and corrugated tube 6 are around forming a vacuum lumen 2; Described diaphragm 5 connection transmission bar 7 lower ends and this transmission bar 7 other ends pass corrugated tube 6 straight up and are connected with movement 8.Be evacuated to different vacuum tightness (being negative pressure) by the different range of instrument in this vacuum lumen 2, exocoel 1 wherein is by diaphragm 5 and following connector 4 is formed and lead directly to atmosphere or vacuum pump by joint; When absolute pressure off-balancesheet chamber 1 is vacuumized (negative pressure), before the upper limit that is evacuated to the absolute pressure table, because the negative pressure of inner chamber 2 is greater than exocoel 1 negative pressure, pointer should stop upper limit position, when having only exocoel 1 negative pressure greater than inner chamber 2 negative pressure, 5 on diaphragm is subjected to displacement downwards, and fans tooth by transmitting on the bar 7 drive movements 8, pointer is deflected, to reach the purpose of measuring absolute pressure.
Claims (1)
1. novel pressure table, comprise exocoel (1), inner chamber (2) and movement (8), it is characterized in that: describedly go up that connector (3) is connected with following connector (4) and in cavity of inside formation, this cavity is divided into exocoel (1) and inner chamber (2) by diaphragm (5), and corrugated tube (6) is installed in inner chamber (2) top; Described diaphragm (5) connects transmission bar (7) lower end, and this transmission bar (7) other end passes corrugated tube (6) straight up and is connected with movement (8).
