Abstract
The utility model discloses a novel stop valve. It includes valve body, valve clack, divided ring, valve clack lid, valve rod and valve gap, is provided with the valve clack in the valve body, is provided with the divided ring in the valve clack, and the valve clack top is provided with the valve clack lid, and the valve rod cooperatees with the valve clack, cooperatees through bolt and valve gap in the valve body top. The utility model has the characteristics of valve body center height reduces, and processing is convenient, and is with low costs, and is sealed reliable, does not have the wearing and tearing scotch, and opening torque is little, and the operation is light.
Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of novel cutoff valve.
Background technique
Stop valve is a kind of block valve of forced seal formula, is mainly used to the medium connected or block in pipeline.It is simple that stop valve has structure, easy to maintenance, sealing surface scuffing not easy to wear, the advantage of long service life, the MEDIA FLOW of existing stop valve is generally flow into by below flap, flow out from the top of flap, mesohigh or heavy caliber stop valve allow medium to flow into above flap, and unlatching moment is large like this, traditional employing internal bypass and outer bypass reach pressure at both sides balance, internal bypass complicated structure, valve mass increases, and cost improves; Outer by-pass structure makes valve increase the weight of, and installs complicated, and operation inconvenience and cost improve.
In sum, need to design a kind of novel cutoff valve.
Model utility content
For solving the problem, the utility model provides a kind of novel cutoff valve, and have valve body center height and reduce, easy to process, cost is low, seals reliable, and without wearing and tearing scratch, unlatching moment is little, operates light feature.
For achieving the above object, the technological scheme that the utility model is taked is: a kind of novel cutoff valve, comprise valve body, flap, divided ring, valve clack cover, valve rod and valve gap, flap is provided with in valve body, divided ring is provided with in flap, flap top is provided with valve clack cover, and valve rod matches with flap, and body top is matched with valve gap by bolt.
As preferably, described valve rod lower end adopts spheric structure.
As preferably, described valve rod underpart sphere pile-up welding hard alloy.
As preferably, described flap internal channel mouth adopts and is not more than the wide sealing surface of 0.15mm.
The utility model has following beneficial effect: have valve body center height and reduce, easy to process, cost is low, seals reliable, and without wearing and tearing scratch, unlatching moment is little, operates light feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In order to make the purpose of this utility model and advantage clearly understand, below in conjunction with embodiment, 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.
As shown in Figure 1, the utility model embodiment provides a kind of novel cutoff valve, comprise valve body 1, flap 2, divided ring 3, valve clack cover 4, valve rod 5 and valve gap 6, flap 2 is provided with in valve body 1, divided ring 3 is provided with in flap 2, flap 2 top is provided with valve clack cover 4, and valve rod 5 matches with flap 2, is matched with valve gap 6 by bolt in valve body 1 top.
This embodiment eliminates an interior flap and interior valve clack cover, and valve rod lower end adopts spheric structure, is directly used for interior flap and forms linear sealing pair with flap, valve rod lower end sphere pile-up welding hard alloy, flap internal channel mouth adopts and is less than or equal to the wide sealing surface of 0.15mm, and pile-up welding hard alloy, there is valve body center height and reduce, easy to process, cost is low, and sealing is reliable, without wearing and tearing scratch, unlatching moment is little, operates light feature.
The structure of this embodiment is simple, and volume is little, compact dimensions, good seal performance, long service life, and open and close moment low, cost is low, and quality is light, is applicable to mesohigh larger caliber valve.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
