Abstract
The utility model relates to a gas sampling test device, in particular to a harmful gas sampling test gun. A sealing device of the harmful gas sampling test gun comprises a sampling gun and a blind plate, wherein a hole is formed in the center of the blind plate; the sampling gun passes through the hole in the center of the blind plate; a rubber annular sealing piece is arranged between the sampling gun and the blind plate; and the diameters of the blind plate, the rubber annular sealing piece, the hole of the blind hole and an inner hole of the rubber annular sealing piece gradually decrease. According to the sealing device of the harmful gas sampling test gun, the emission of harmful fume on the site is eliminated, and accident potential is reduced.
Description
Technical field
The utility model relates to the gas sampling proving installation, relates in particular to a kind of harmful gas sampling Testing gun.
Background technology
In flue gas monitoring, often touch the monitoring of some high-risk gases.If leak, can cause serious hazard to person to the operating personnel, not only cause personnel's respiratory tract, nervous system injury, and serious words entail dangers to life security.In order to guarantee operating personnel's safety, the sample collector need carry oxygen breathing apparatus and sample at the scene.Oxygen breathing apparatus because of bulky, deadweight is bigger, and need replenish high purity oxygen gas before use, has had a strong impact on operating efficiency.What is more important, the service time of oxygen breathing apparatus is limited, in actual job, usually can't satisfy the monitoring requirement.This work efficiency to the scene has received great influence.
Summary of the invention
The utility model is intended to address the above problem, and a kind of harmful gas sampling Testing gun packoff is provided.The utility model has been eliminated on-the-spot harmful smoke discharge capacity, has reduced accident potential.
For addressing the above problem; A kind of harmful gas sampling of the utility model Testing gun packoff; It comprises sampling rifle and blind plate, said blind plate center drilling, and the sampling rifle passes the blind plate center pit; Be provided with the rubber lip ring, said blind plate diameter between sampling rifle and the blind plate>rubber annular seal diameter>the blind plate bore dia>rubber lip ring diameter of bore.
Described a kind of harmful gas sampling Testing gun packoff, the annular solid outer wall of described rubber lip ring is provided with the groove of annular.
Simple, convenient, the easy row of the utility model; Can effectively adopt of the harm of isolated harmful smoke, eliminate on-the-spot harmful smoke discharge capacity, reduce accident potential the operating personnel; And can realize the sampling and the test of harmful smoke smoothly, can effectively promote the work efficiency of sampling and test.This method has wide range of applications, and can be applicable to the collection and the test of harmful smoke.In the environmental monitoring field good application value is arranged.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify:
Fig. 1 is the utility model synoptic diagram.
Embodiment
As shown in Figure 1; The utility model comprises the blind plate 1 of center drilling and the rubber lip ring 2 that matches with blind plate, the machinery perforate in blind plate 1 center, and the rubber lip ring 2 of sealing perforate with blind plate 1 being used to of matching is processed to groove shapes; The blind plate thickness of recess width and perforate is suitable; The center drilling of blind plate is stuck in the groove of rubber lip ring just, and the both sides of blind plate are in fact all coated by the rubber lip ring, guarantee impermeability.The machinery perforate of described rubber lip ring 2 centers; Can sampling rifle Testing gun 1 be filled at tapping; Guarantee the blind plate diameter>rubber annular seal diameter>the blind plate opening diameter>rubber lip ring opening diameter; So both can guarantee system's impermeability again so that sampling rifle or Testing gun 1 freely stretch.Said blind plate 1 is provided with the ellipticity bolt hole, is applicable to the fixing of bolt on the different bore size flanges.
