Abstract
The utility model relates to a kind of valve, comprise valve body, handle, valve rod and valve plug, described valve body side is provided with water inlet, opposite side is provided with osculum, described valve inner is provided with water channel, is provided with several the first seal rings between described valve rod and valve body along vertical direction, and described valve plug upper-end surface is provided with the second seal ring, the lower end surface of described valve plug is connected with lower seal by latch assembly, and described lower seal is convex structure.The utility model is by arranging several first seal rings and the second seal ring, like this when valve is in open state, first seal ring can realize multi-stage sealed effect, anti-sealing is revealed, second seal ring plays seal action further simultaneously, efficiently solve the fluid leakage problems of valve when open state, practical, low cost of manufacture and convenient later maintenance; By arranging the lower seal of convex structure, effectively solve the fluid leakage problem of valve when closed state, practicability is good.
Description
Technical field
The utility model relates to field of mechanical technique, particularly relates to a kind of valve.
Background technique
Equipment, refers to supply people's Long-Time Service aborning, and substantially in Reusability keeps original physical form and the means of production of function and the general name of material goods.The equipment facility equipment aggregate that normally a group is medium-and-large-sized, all cannot take operation and must have fixing pedestal, uses power supply and so on power to operate and impersonal force.
Generally speaking equipment be all placed on exclusive room such as machine room, workshop, factory building, because noise or waste gas can be produced during running, all except invisible information except information equipment is input output, the material that much equipment wants input output tangible, so more need the ability smooth operation of custom-designed place.The kind of equipment and spare part is a lot, for the ease of management and supply, general by following classification.1. part classification is divided; 2. part source divides; 3. part operating characteristic is divided; Standing: refer to often to use, the large and single AUTOMATIC PACKING MACHINE valency of equipment idle cost is lower, the part that needs often to keep certain storage level; 4. spare part precision and manufacture complexity are divided; Key component: refer to the part that precision is high, manufacture difficulty plays a crucial role greatly, in a device.General part: refer to other mechanical spare part except key component.
Valve, as the switch controlling device in the airtight transmitting procedure of flowing medium, uses very extensive in society.Valve of the prior art mainly relies on the lower seal of valve acrosome lower end surface, when valve is in closedown, lower seal can stop the liquid leakage in pipeline, but lower seal is generally plane, time has been grown and has also easily caused leaking, simultaneously when valve is in open state, when namely valve acrosome is in uppermost position in fig-ure, valve gap, interior pad between valve stem casing and valve rod or stuffing box gland can only be relied on to play seal action.This kind of valve is long-term opening, in closed using process, and in it, pad or the stuffing box gland inevitably phenomenon such as aging, loosening, finally causes liquid leakage in pipeline.Therefore, for solving the problem, spy provides a kind of new technological scheme.
Model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of valve.
The utility model is achieved through the following technical solutions:
A kind of valve, comprise valve body, handle, valve rod and valve plug, described valve body side is provided with water inlet, opposite side is provided with osculum, described valve inner is provided with water channel, is provided with several the first seal rings between described valve rod and valve body along vertical direction, and described valve plug upper-end surface is provided with the second seal ring, the lower end surface of described valve plug is connected with lower seal by latch assembly, and described lower seal is convex structure.
As optimal technical scheme of the present utility model, state the first seal ring for two or three.
As optimal technical scheme of the present utility model, the diameter of described second seal ring is greater than the diameter of the first seal ring.
As optimal technical scheme of the present utility model, described latch assembly is lock washer and locking nut.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, the utility model by arranging several first seal rings and the second seal ring, like this when valve is in open state, first seal ring can realize multi-stage sealed effect, anti-sealing is revealed, and the second seal ring plays seal action further simultaneously, efficiently solves the fluid leakage problems of valve when open state, practical, low cost of manufacture and convenient later maintenance; By arranging the lower seal of convex structure, effectively solve the fluid leakage problem of valve when closed state, practicability is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1. valve body; 2. handle; 3. water inlet; 4. osculum; 5. water channel; 6. valve rod; 7. valve plug; 8. the first seal ring; 9. the second seal ring; 10. lower seal; 11. latch assemblies.
Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Refer to Fig. 1, Fig. 1 is structural representation of the present utility model.
A kind of valve, comprise valve body 1, handle 2, valve rod 6 and valve plug 7, described valve body 1 side is provided with water inlet 3, opposite side is provided with osculum 4, described valve body 1 inside is provided with Aquaporin-5, be provided with several the first seal rings 8 along vertical direction between described valve rod 6 and valve body 1, wherein said first seal ring 8 is two or three.Described valve plug 7 upper-end surface is provided with the second seal ring 9, and the diameter of wherein said second seal ring 9 is greater than the diameter of the first seal ring 8.Like this when valve is in open state, the first seal ring 8 can realize multi-stage sealed effect, and anti-sealing is revealed, second seal ring 9 plays seal action further simultaneously, efficiently solve the fluid leakage problems of valve when open state, practical, low cost of manufacture and convenient later maintenance.
The lower end surface of described valve plug 7 is connected with lower seal 10 by latch assembly 11, wherein said latch assembly 11 is lock washer and locking nut, described lower seal 10 is in convex structure, such lower seal 10 is better in hydraulic pressure effect seal performance, effectively solve the fluid leakage problem of valve when closed state, practicability is good.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
