Abstract
The utility model relates to a rust-proof safety valve. The rust-proof safety valve mainly solves the problems that an existing safety valve is poor in humidity resistance and a spring easily rusts. A water absorption portion is arranged between a guide sleeve and a spring base and matched with the guide sleeve in a transition mode. A valve rod is sleeved with the water absorption portion. The spring and the spring base are coated with rust-proof layers. The rust-proof safety valve is good in humidity resistance, dryness in a valve deck can be kept, the problems that the spring and the spring base easily rust are solved, the valve does not need to be replaced frequently, and the service life of the valve is prolonged.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of antirust safety valve.
Background technique
Safety valve is when acting on holder power on spool when fluid pressure and be greater than the default pressure of pressurized container, and flap is just lifted off a seat by jack-up, liquid pressure release, and safety valve is opened; When the pressure of liquid is less than the holder acting on flap and defeats the default pressure of force container, flap presses down with valve seat again closely sealed, and liquid stops releasing, and safety valve cuts out.But traditional safety valve is when pressure release or closed safe valve, and valve rod, under the effect of spring, can move up and down.Be connected in the valve rod above flap, when letting out valve, the water that can bring fraction into enters valve gap, long-term such work, and moisture can easily be made getting rusty of spring, makes valve body well pressure release and sealing, has shortened the life time of valve.
Summary of the invention
In order to overcome the deficiency of background technique, the utility model provides a kind of antirust safety valve, mainly solved the problem that the bad spring of existing safety valve humidity resistance easily gets rusty, this safety valve can be good at protection against the tide, guaranteed the mass dryness fraction in valve gap, solved the problem that spring and spring seat can get rusty, energy long-term work, need not often change, extend the life time of valve.
The technological scheme that the utility model adopts is: a kind of antirust safety valve, comprise valve body, flap, valve gap, described flap is provided with guide sleeve, described valve rod and guide sleeve size are suitable, on described valve rod, be arranged with spring, described spring is located on the spring seat suitable with spring, described spring is set on valve rod together with spring seat, between described guide sleeve and spring seat, be provided with water suction portion, described water suction portion and guide sleeve transition fit, described water suction portion is sheathed on valve rod, on described spring and spring seat, scribbles resin layer.
By adopting technique scheme, when fluid pressure acts on holder power on spool and is greater than the default pressure of pressurized container, flap is just lifted off a seat by jack-up, liquid pressure release, spring band ovable valve stem moves upward, a small amount of moisture can be along with the motion of valve rod, bring in valve gap, the water suction portion that is provided with above of guide sleeve, the a small amount of moisture being brought into will be absorbed by water suction portion, the moisture being brought into just can not enter in valve gap, cause the interior humidity of lid too large, in long-term such situation, getting rusty of the spring easily causing and spring seat, and oiling rust proof paint also on spring and spring seat, such design allows spring and spring seat be difficult for getting rusty, extended the life time of spring and spring seat, also extended the working life of valve, guaranteed the normal working efficiency of valve.
The utility model is further set to: described water suction portion comprises the fixing part of fixedly water suction portion, and described fixing part is fixedly connected on valve gap inwall.
By adopting technique scheme, utilize fixing part to fix water suction portion, make the soundness of water suction portion better, make the better tightness of water suction portion and valve gap inwall, can better prevent that moisture from entering in valve gap, make spring and spring seat be difficult for getting rusty, extend the life-span of using.
The utility model is further set to: described flap surface is coated with cobalt-based nichrome, and described water suction portion scribbles rubber layer with respect to the one side of spring seat.
By adopting technique scheme, cobalt-based nichrome is the cemented carbide of a kind of ability all kinds abrasion and corrosion and high temperature oxidation, and this alloy on the plated surface of flap can strengthen the wearability of flap; On water suction portion surface, scribble rubber layer; utilize high elasticity, the impermeability of rubber; water suction portion is conflicted on the surface of spring seat; neither can scrape spring seat surface; can meet again sealing, fluid-tight effect, well protect spring seat and spring, can not be subject to the impact of moisture; there is corrosion phenomenon, extended the life-span of using.

Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further.
As shown in Figure 1 with Figure 2, a kind of antirust safety valve, comprise valve body 1, flap 2, valve gap 3, described flap 2 is provided with guide sleeve 4, described valve rod 5 is suitable with guide sleeve 4 sizes, on described valve rod 5, be arranged with spring 6, described spring 6 is located on the spring seat 7 suitable with spring 6, described spring 6 is together with spring seat 7 on sheathed and valve rod 5, between described guide sleeve 4 and spring seat 7, be provided with water suction portion 8, described water suction portion 8 and guide sleeve 4 transition fit, described water suction portion 8 is sheathed on valve rod 5, on described spring 6 and spring seat 7, scribbles resin layer.When fluid pressure acts on holder power on spool and is greater than the default pressure of pressurized container, flap 2 is just lifted off a seat by jack-up, liquid pressure release, spring 6 band ovable valve stems 5 move upward, a small amount of moisture can be along with the motion of valve rod 5, bring in valve gap 3, the water suction portion 8 that is provided with above of guide sleeve 4, the a small amount of moisture being brought into will be absorbed by water suction portion 8, the moisture being brought into just can not enter in valve gap 3, cause the interior humidity of valve gap 3 too large, in long-term such situation, getting rusty of the spring 6 easily causing and spring seat 7, and oiling rust proof paint also on spring 6 and spring seat 7, such design allows spring 6 and spring seat 7 be difficult for getting rusty, extended the life time of spring 6 and spring seat 7, also extended the working life of valve, guaranteed the normal working efficiency of valve.
Described water suction portion 8 comprises the fixing part 9 of fixedly water suction portion 8, and described fixing part 9 is fixedly connected on valve gap 3 inwalls.Utilize fixing part 9 to fix water suction portion 8, make the soundness of water suction portion 8 better, make the better tightness of water suction portion 8 and valve gap 3 inwalls, can better prevent that moisture from entering in valve gap 3, make spring 6 and spring seat 7 be difficult for getting rusty, extended the life-span of using.
Described flap 2 surfaces are coated with cobalt-based nichrome, and described water suction portion 8 scribbles rubber layer with respect to the one side of spring seat 7.Cobalt-based nichrome is the cemented carbide of a kind of ability all kinds abrasion and corrosion and high temperature oxidation, and this alloy on the plated surface of flap 2 can strengthen the wearability of flap 2; On water suction portion 8 surfaces, scribble rubber layer; utilize high elasticity, the impermeability of rubber; water suction portion 8 is conflicted on the surface of spring seat 7; neither can scrape spring seat 7 surfaces; can meet again sealing, fluid-tight effect, well protect spring seat 7 and spring 6, can not be subject to the impact of moisture; there is corrosion phenomenon, extended the life-span of using.
Every technician's notice: although the utility model describes according to above-mentioned embodiment; but invention thought of the present utility model is not limited in this model utility; the repacking of any utilization inventive concept, all will include in this patent scope of patent protection.
