The exhaust structure of the sliding valve vacuum pump is characterized in that an oil-gas separator is connected in series with the exhaust pipe. The exhaust structure has a good separation effect, an oil-saving effect is achieved, environment is protected, the internal structure of a pump body is not required to be changed, performance is improved, and initial functions are not influenced.
Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of vacuum pump, particularly the sliding valve vacuum pump exhaust structure.
Background technique
Sliding valve vacuum pump is a kind of variable capacity gas transmission pump, is widely used in very much the vacuum system of industry, scientific experiment at present, and it has reliable operation, easy to operate advantage.The work of sliding valve vacuum pump be unable to do without vacuum oil, but because the working principle of slide valve pump, the gas that relief opening is discharged is often mixing oil, has so not only wasted the pollution that vacuum oil has also caused environment.
Summary of the invention
The purpose of the utility model is to have the problems referred to above to existing technology, has proposed a kind of sliding valve vacuum pump exhaust structure, and this sliding valve vacuum pump exhaust structure can be realized the Oil-gas Separation and the oil return of sliding valve vacuum pump work exhaust.
The purpose of the utility model can realize through following technical proposal: a kind of sliding valve vacuum pump exhaust structure, comprise outlet pipe, and it is characterized in that, be serially connected with a deaerator on the described outlet pipe.When sliding valve vacuum pump was worked, because pressure effect gas in the jar passes through outlet pipe in deaerator, the gas that oil gas mixes was realized separating in separator.
In above-mentioned sliding valve vacuum pump exhaust structure, described deaerator is the vertical oil-gas separator.Oil converges in separator, in deaerator, precipitates then, and vertical deaerator separating effect is better.
In above-mentioned sliding valve vacuum pump exhaust structure, the return opening place of described deaerator is connected with the gas ballast valve assembly that when return opening is in negative pressure state, can prevent gas backstreaming.Be connected through the oil return flexible pipe between the return opening place of deaerator and the gas ballast valve, when sliding valve vacuum pump work is in negative pressure state, because the pressure effect is pushed back in the active chamber realization oil return through separating the oil that deposit in the deaerator.
In above-mentioned sliding valve vacuum pump exhaust structure, described sliding valve vacuum pump has the air supply passage that is connected with chamber, and described gas ballast valve assembly is arranged on the air supply passage place.When the tonifying Qi of the excessive need of sliding valve vacuum pump need pressure reduction, the fluid oil return of separating this moment is accomplished, and gas carries out the adjusting of pressure reduction in air supply passage enters into active chamber.
In above-mentioned sliding valve vacuum pump exhaust structure; Described gas ballast valve assembly comprises one-way valve and flow control valve; The outlet of described flow control valve is connected with check valve inlet, and the import of described flow control valve is connected with the return opening of deaerator through flexible pipe; Described one-way valve outlet is connected with the import of air supply passage.One-way valve can prevent the inherent air pressure height of active chamber and with the situation that oil pressure goes out, effectively solve the problem of slide valve pump oil spout; Flow control valve can be regulated recirculating oil quantity and air compensation as required.
In above-mentioned sliding valve vacuum pump exhaust structure, described gas ballast valve assembly also comprises first-class ball valve, and the outlet of described flow control valve all is connected with the outlet of stream ball valve with check valve inlet, and flow control valve is positioned at the top of stream ball valve.The stream ball valve is used to control the break-make between air supply passage and the oil return flexible pipe.
Compared with prior art, this sliding valve vacuum pump exhaust structure has the following advantages:
1, adopt the vertical oil-gas separator, separating effect is better, has not only played fuel-efficient effect, has also protected environment.
2, the design of return line, compact structure, effect are obvious, need not to change pump housing internal structure and only need add valve and get final product.
Do not influence original function when 3, improving performance.
Description of drawings
Fig. 1, Fig. 2 are the part-structure schematic representation of the utility model.
Among the figure, 1, outlet pipe; 2, deaerator; 3, gas ballast valve assembly; 3a, one-way valve; 3b, flow control valve; 3c, stream ball valve; 4, flexible pipe; 5, air supply passage.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
Like Fig. 1, shown in Figure 2, a kind of sliding valve vacuum pump exhaust structure comprises outlet pipe 1, is serially connected with a deaerator 2 on the outlet pipe 1, and deaerator 2 is a vertical oil-gas separator 2; The return opening place of deaerator 2 is connected with the gas ballast valve assembly 3 that when return opening is in negative pressure state, can prevent gas backstreaming.Sliding valve vacuum pump has the air supply passage 5 that is connected with chamber; Gas ballast valve assembly 3 is arranged on air supply passage 5 places; Comprise one-way valve 3a and flow control valve 3b; The outlet of flow control valve 3b is connected with one-way valve 3a import, and the import of flow control valve 3b is connected through the return opening of flexible pipe 4 with deaerator 2; One-way valve 3a outlet is connected with the import of air supply passage 5.Gas ballast valve assembly 3 also comprises first-class ball valve 3c, and the outlet of flow control valve 3b all is connected with the outlet of stream ball valve 3c with one-way valve 3a import, and flow control valve 3b is positioned at the top of stream ball valve.
When sliding valve vacuum pump was worked, the mixture of aqueous vapor and oil gas can be discharged through outlet pipe 1, owing to be provided with deaerator 2 in outlet pipe 1 outlet port; Because the effect of deaerator 2; Oil gas is deposited as fluid and is stored in oil return flexible pipe 4 and the deaerator 2, and when return opening was in negative pressure state, the fluid of separating through deaerator 2 is pushed back realized oil return in the active chamber; When inside and outside differential pressure is excessive; Active chamber in the pump housing need carry out tonifying Qi, and oil return this moment is accomplished, thus the working pressure of gas in air supply passage 5 gets into active chamber Control work chamber.Be provided with an one-way valve 3a cleverly at the return opening place, this one-way valve 3a can prevent when the active chamber air pressure inside is high and fluid is extruded the situation outside the pump housing, effectively solve the fuel injection event of sliding valve vacuum pump; The size of flow control valve 3b may command oil return flow and air compensation; Stream ball valve 3c can control the break-make between oil return flexible pipe 4 and the air supply passage 5 fast.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
