Abstract
The utility model relates to a vacuum tail gas check device including a check valve body. The vacuum tail gas check device is characterized in that a vacuum tail gas inlet is arranged on the lower end of the valve body, and a plastic disc is abutted joint on the end face in the inner cavity of the check valve body where the vacuum tail gas inlet is situated to isolate vacuum tail gas and is driven by an elastic mechanism. The vacuum tail gas check device is simple in structure, and convenient for operation, and ensures smooth flow of vacuum tail gas and smooth production.
Description
Technical field
The utility model relates to a kind of vacuum tail gas check device, is applied to the processing to vacuum tail gas.
Background technique
Present safety check has a variety of; But but do not have a kind ofly can really be applicable to processing to this special gas of vacuum tail gas; Because vacuum tail gas air pressure is lower, can't be effectively the spool of the heaviness in the present safety check be backed down, thereby can't accomplish flat requirement.Therefore, to the problems referred to above be the object of the utility model research.
Summary of the invention
The purpose of the utility model is to provide a kind of vacuum tail gas check device, and having solved present safety check effectively can't help ensureing that vacuum tail gas circulates smoothly to the problem of vacuum tail gas application.
The utility model is characterised in that: a kind of vacuum tail gas check device; Comprise check valve body; It is characterized in that: the lower end of said valve body is provided with vacuum tail gas suction port, and said suction port is arranged in that apical grafting has the plastic disc in order to intercept vacuum tail gas and to be driven by elastic mechanism on the end face of check valve body inner chamber.
The advantage of the utility model: the utility model is simple in structure, and is easy and simple to handle, can effectively ensure the circulation smoothly of vacuum tail gas ground, ensures and produces.
Description of drawings
Fig. 1 is the utility model example structure schematic representation.
Fig. 2 is the utility model embodiment operating process structural representation.
Embodiment
With reference to figure 1 and Fig. 2; A kind of vacuum tail gas check device; Comprise check valve body 1, the lower end of said valve body 1 is provided with vacuum tail gas suction port 2, and said suction port 2 is arranged in that apical grafting has the plastic disc 4 in order to intercept vacuum tail gas and to be driven by elastic mechanism 3 on the end face of check valve body inner chamber.
Above-mentioned elastic mechanism 3 comprises respectively perpendicular driveshaft 3-1 and the Returnning spring 3-2 of putting that is connected with plastic disc 4 upper-end surfaces, and the perpendicular driveshaft 3-1 that puts is set in the said Returnning spring 3-2.
Also be provided with air outlet 5 on the above-mentioned valve body 1.
The practical implementation process: after being nested with this device,, this device can effectively being brought into play to the lower characteristics of vacuum tail gas air pressure do because disk adopts plastic member, and is driven by elastic mechanism.
The above is merely the preferred embodiment of the utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model.
Claims (3)
1. vacuum tail gas check device; Comprise check valve body; It is characterized in that: the lower end of said valve body is provided with vacuum tail gas suction port, and said suction port is arranged in that apical grafting has the plastic disc in order to intercept vacuum tail gas and to be driven by elastic mechanism on the end face of check valve body inner chamber.
2. vacuum tail gas check device according to claim 1 is characterized in that: said elastic mechanism comprises respectively perpendicular driveshaft and the Returnning spring put that is connected with the plastic disc upper-end surface, and the perpendicular driveshaft of putting is set in the said Returnning spring.
