Abstract
The invention discloses a safety valve comprising a valve body, a valve stem, a valve bonnet and an adjusting cap. The valve body is provided with an upper opening, a lower opening and a side opening, the upper opening of the valve body is connected with the valve bonnet in a threaded manner, the valve stem is arranged in the valve body, the top of the valve bonnet extends to form an upper bulge loop, the adjusting cap is connected with the bulge loop in a threaded manner, the upper end of the valve stem penetrates through the valve bonnet and is fixedly connected with a retaining plate, and a spring is arranged between the retaining plate and the adjusting cap. By the aid of the above technical scheme, the safety valve is compact in structure and has the advantages of good control adjustment, safety, reliability, convenience in use and good stability.
Description
Technical field
The present invention relates to a kind of safety valve.
Background technique
The advantages such as safety valve has that structure is simple and direct, stable performance, easy installation and removal, corrosion-resistant, favorable sealing property, using scope is wide, the life-span is long, it is the valve of a kind of advanced safety control in power station, oil refining, chemical plant installations and the instrument measurement pipeline, develop rapidly along with industries such as iron and steel, space flight, chemical industry, oil refining, coalification and shipbuildings, the gas control security is more and more important in application, and convenient, safe, the stable demand on using is improved greatly; Originally domestic safety valve is subjected to the Restricted requirements such as material, technology, the main again appearance plating mode of irony, copper material that uses, all exist larger potential safety hazard on its Security stability and the corrosion resistance in abominable and etchant gas occasion, working life is short, and waste greatly; Therefore, in today of economic development, a kind of new and effective safe, stable, reliable auxiliary products that match with it of market demand, ensure quality is reliable, more pays attention to protection safety, long service life.
Summary of the invention
Technical problem to be solved by this invention provides a kind of safety valve, and compact structure has good regulating and controlling, safe, reliable, easy to use and good stability.
For solving the problems of the technologies described above, the present invention adopts following technological scheme: safety valve, comprise valve body, valve rod, bonnet, adjusting cap, described valve body has upper shed, under shed and side opening, the upper shed of described valve body and described bonnet are threaded connection, described valve rod is located in the described valve body, the top of described bonnet has extended upward a upper bulge loop, bulge loop is threaded described adjusting cap with being somebody's turn to do upward, a baffle plate is passed and be fixedly connected with in the upper end of described valve rod by described bonnet, is provided with a spring between described baffle plate and the described adjusting cap.
As preferably, be provided with seal ring between described valve body and the bonnet.
As preferably, the bottom of described bonnet is extended with a lower convex ring downwards, is provided with seal ring between the inwall of described valve rod and described lower convex ring.
The present invention is owing to having adopted technique scheme, compact structure to have good regulating and controlling, safe, reliable, easy to use and good stability.
Description of drawings
Fig. 1 is structural representation of the present invention
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Figure 1 shows that safety valve of the present invention, comprise valve body 1, valve rod 2, bonnet 3, regulate cap 4, described valve body 1 has upper shed, under shed and side opening, the upper shed of described valve body 1 and described bonnet 3 are threaded connection, described valve rod 2 is located in the described valve body 1, the top of described bonnet 3 has extended upward a upper bulge loop 31, bulge loop 31 is threaded described adjusting cap 4 with being somebody's turn to do upward, a baffle plate 21 is passed and be fixedly connected with in the upper end of described valve rod 2 by described bonnet 3, is provided with a spring 5 between described baffle plate 21 and the described adjusting cap 4.Be provided with seal ring 6 between described valve body 1 and the bonnet 3.The bottom of described bonnet is extended with a lower convex ring 32 downwards, is provided with seal ring 6 between the inwall of described valve rod 2 and described lower convex ring 32.
When safety valve of the present invention surpasses pipeline setting pressure load when the loine pressure overload, the release of pressure discharging; That safety valve has is simple for structure, stable performance, the performance such as corrosion-resistant, high temperature resistant; Valve body adopts 316SS high-quality stainless steel material integral structure, effective Leakage prevention, and spring adopts high-quality 301 stainless steels, and has a corrosion-resistant function, long service life, spring can be changed according to pressure set points, in order to be applicable to various pressure setting scope; Product is for different working mediums and environmental conditions, the various selection of sealing material.Valve body adopts the high-quality stainless steel, and seal ring adopts teflon, has guaranteed the corrosion resistance of product, the working life of having improved product; Spring can be changed, in order to be applicable to various pressure setting scope.
