Abstract

The utility model provides a get rid of gaseous muddy air cavity of cavity, the casing that has the cavity in including, a serial communication port, still including the piston rod that can follow the motion of cavity length direction, the one end of piston rod is located outside the casing, the other end stretches into in the cavity, being located the tip of cavity, the piston rod be equipped with the baffle on, it is two parts of mutually independent to be separated the cavity by the baffle, be cavity no. 1 and cavity no. 2, be equipped with on the casing with a cavity communicating air inlet, be equipped with at least one gas outlet along its length direction on the casing, promote piston rod along cavity length direction motion behind the gaseous entering air inlet, a plurality of empirical formulas are observed, a cavity escalation, and simultaneously, cavity no. 2 constantly reduces. The utility model discloses a gas mixing device is compared with present technique, mainly can come simple assurance to mix the gaseous purity in the air cavity through the piston, and it has the loaded down with trivial details of air to have avoided taking cavity central plains out with the help of the vacuum pump.

Description

A kind of mixed air cavity getting rid of cavity gas

Technical field

The utility model relates to a kind of simple gas hybrid chamber, does not need by the original air of vacuum pump emptying cavity, can meet the fundamental principle that the steady air flow that gas-osculum is given vent to anger is mixed in osculum air inlet-large chamber.

Background technology

Discharge after multiple gases mixes in gas mixing chamber, it must meet the fundamental principle that the steady air flow that gas-osculum is given vent to anger is mixed in osculum air inlet-large chamber.Gas mixing chamber needs the original gas in cavity to discharge before new gas enters, existing gas mixing chamber or vacuumize in cavity by vacuum pump, or in cavity, fills into air-flow for a long time to reach the object of being discharged by original gas.Above-mentioned two kinds of modes or cost is higher, or inefficiency.

Summary of the invention

The purpose of this utility model is to provide a kind of gas mixing chamber efficiently can not discharged by original gas by any peripheral equipment.

In order to achieve the above object, the technical solution of the utility model there is provided a kind of mixed air cavity getting rid of cavity gas, the cylindrical housings of chamber is had in comprising, it is characterized in that, also comprise the piston rod that can move along chamber length direction, one end of piston rod is positioned at outside housing, the other end stretches in chamber, the end being positioned at chamber at piston rod is provided with dividing plate, by dividing plate, chamber is divided into two separate parts, i.e. chamber one and chamber two, housing is provided with the inlet mouth communicated with chamber one, housing is provided with at least one air outlet along its length, gas promotes piston rod and moves along chamber length direction after entering inlet mouth, in the process, chamber one constantly increases, simultaneously, chamber two constantly reduces.

Gas mixer of the present utility model, compared with prior art, mainly simply can ensure the gas purity in mixed air cavity by piston, avoid and have the loaded down with trivial details of air by vacuum pump extraction cavity Central Plains.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of form of the present utility model;

Fig. 2 is the structural representation of another kind of form of the present utility model.

Embodiment

For making the utility model become apparent, hereby with preferred embodiment, and accompanying drawing is coordinated to be described in detail below.

As shown in Figures 1 and 2, a kind of mixed air cavity getting rid of cavity gas that the utility model provides, the piston rod 2 having the housing 1 of chamber in comprising and can move along chamber length direction, one end of piston rod 2 is positioned at outside housing 1, the other end stretches in chamber, the end being positioned at chamber is provided with dividing plate 3, by dividing plate 3, chamber is divided into two separate parts at piston rod 2, i.e. chamber one and chamber two, housing 1 is provided with the inlet mouth 4 communicated with chamber one.As shown in Figure 1, housing 1 is provided with an air outlet 5 along its length, can be used for bell-jar reaction cavity (not shown), or as shown in Figure 2, be provided with multiple air outlet 5, can external flat reaction cavity (not shown).Promote piston rod 2 after gas enters inlet mouth 4 to move along chamber length direction, in the process, chamber one constantly increases, and meanwhile, chamber two constantly reduces.

Piston rod 2 of the present utility model remains on zero position before air inlet, now the volume of chamber one is zero, rear gas passes into inlet mouth 4, air pressure is relied on progressively to be promoted by piston rod 2, until piston rod 2 arrives bottom housing 1, now chamber one volume reaches maximum, and is discharged by original air easily by piston rod 2, to ensure the purity of internal gas, gas enters required reaction zone by air outlet 5.

Claims

1. get rid of the mixed air cavity of cavity gas for one kind, the housing (1) of chamber is had in comprising, it is characterized in that, also comprise the piston rod (2) that can move along chamber length direction, one end of piston rod (2) is positioned at housing (1) outward, the other end stretches in chamber, the end being positioned at chamber at piston rod (2) is provided with dividing plate (3), by dividing plate (3), chamber is divided into two separate parts, i.e. chamber one and chamber two, housing (1) is provided with the inlet mouth (4) communicated with chamber one, housing (1) is provided with at least one air outlet (5) along its length, gas enters inlet mouth (4) and promotes piston rod (2) afterwards and move along chamber length direction, in the process, chamber one constantly increases, simultaneously, chamber two constantly reduces.
