Abstract
The utility model discloses an air inlet device of a safety valve. The air inlet device of the safety valve comprises a safety valve body, an air inlet pipeline and a sealing piece which is arranged on the air inlet pipeline. An air inlet hole is formed in the sealing piece. The air inlet channel is fixedly connected with an isolation layer. A small hole is formed in the center of the isolation layer. Due to the fact that the small hole is formed in the center of the isolation layer, gas is preliminarily filtered, the fact that impurities with large particles are not contained by the gas which enters the air inlet hole is guaranteed, the arrangement of the air inlet hole with large bore diameter ensures smooth flow of the gas when the gas enters the safety valve body. The air inlet device of the safety valve has the advantages of being simple in structure and reliable in air inlet mode.
Description
Technical field
The utility model relates to a kind of relief valve assembly, especially a kind of air inlet system of safety valve.
Background technique
Safety valve is a boiler; important safety attachment on pressurized container and other equipment that are stressed; modern industry is more and more higher for the requirement of Safety performance in producing; as often use a kind of standard equipment in the combustion gas field; the intake method of safety valve of the prior art mainly is by offer a micro hole on the Sealing of intake valve port and safety valve main body; filter for the combustion gas that enters in the safety valve valve body by micro hole; but a kind of problem of this set ubiquity; because the aperture of micro hole is very little; in use long after; because the dust in the aging or combustion gas of Sealing; the influence of factors such as particle; make micro hole be plugged through regular meeting, combustion gas can't normally enter the safety valve valve body.
The model utility content
The utility model is plugged easily at safety valve inlet hole of the prior art, and combustion gas can't normally enter the problem of safety valve valve body, and a kind of simple in structure, reliable safety valve air inlet system of intake method is provided.
For achieving the above object, the technical solution of the utility model is:
The safety valve air inlet system comprises the safety valve valve body, and admission line is arranged at the Sealing on the admission line, offers inlet hole on the Sealing, is fixedly connected with separation layer on the admission line, and the center portion of separation layer offers aperture.
As the further setting of such scheme, the diameter of aperture is between 0.2mm～0.3mm.
As the further setting of such scheme, the aperture of inlet hole is at least 0.5cm.
As the further setting of such scheme, separation layer is made by the rigidity resistant material.
The beneficial effects of the utility model are: the aperture of offering by the separation layer center portion tentatively filters the combustion gas that enters in the admission line, make the combustion gas that enters in the safety valve inlet hole can not be mingled with large granular impurities such as dust, the situation that the inlet hole that being provided with like this avoided simultaneously Sealing to cause because of factor such as wear out again is plugged has advantages such as simple in structure, that intake method is reliable.
Description of drawings
Fig. 1 is the prior art constructions schematic representation;
Fig. 2 is a structural representation of the present utility model.
Among the figure: safety valve valve body 1, admission line 2, Sealing 3, inlet hole 4, separation layer 5, aperture 6.
Embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1, a kind of safety valve air inlet system, comprise safety valve valve body 1, admission line 2 is arranged at the Sealing 3 on the admission line 2, offer inlet hole 4 on the Sealing 3, be fixedly connected with separation layer 5 on the admission line 2, the center portion of separation layer 5 offers aperture 6, and the diameter of aperture 6 is at least between 0.2mm～0.3mm, the aperture of inlet hole 4 is at least 0.5cm, and separation layer 5 is made by the rigidity resistant material.
The safety valve air inlet system that the utility model provides is fixedly connected separation layer 5 in admission line 2, and be that the aperture of 0.2～0.3mm tentatively filters the combustion gas that enters in the safety valve valve body 1 by the diameter that separation layer 5 center portions are offered, be unlikely to be mixed with large granular impurities such as dust in the feasible combustion gas that enters in the safety valve valve body 1, combustion gas enters the inlet hole 4 that is arranged on the Sealing 3 after filtering through small holes 6, because the aperture of inlet hole 4 is bigger, both guaranteed that combustion gas entered the unobstructed of safety valve valve body by inlet hole 4, again can be not long or Sealing aging and be plugged because of service time; Separation layer 5 is made by the rigidity resistant material, can guarantee effectively that this device can be by dielectric corrosions such as combustion gas, and long service life.The safety valve air inlet system that the utility model provides has advantages such as simple in structure, that intake method is reliable.
