For achieving the above object, the technical solution of the utility model is as follows:
A kind of pneumatic fast shut-off stop valve, comprise valve gap, valve body, cylinder, flap and the valve rod for driving described flap to move, flap is arranged in valve body chamber; Described flap is provided with a mounting groove, and one end of described valve rod is spelled cap by flap and is arranged in the mounting groove of flap, and the other end of valve rod is connected with cylinder; Be provided with seal ring between described valve gap and valve body, the top of valve gap is provided with stuffing box, and described stuffing box is built with filler; Compressed by support between described valve gap and valve body, be bolted between support and valve body.
In an embodiment of the present utility model, described cylinder is arranged on the top of support, is bolted between the two.
In an embodiment of the present utility model, described valve body is provided with reserving installation hole.
In an embodiment of the present utility model, described valve rod is arranged with swelling spring, one end of described swelling spring is connected with flap, and the other end is connected with valve gap.
In an embodiment of the present utility model, the sealing surface between described flap and valve body is taper.
In an embodiment of the present utility model, described sealing surface place pile-up welding hard alloy.
In an embodiment of the present utility model, described filler is made up of teflon.
By technique scheme, the beneficial effects of the utility model are:
1, compact structure, simple, beautiful shape, manufacture and maintenance is convenient;
2, working stroke is little, and opening and closing time is short;
3, good seal performance, without friction between sealing surface, long service life;
4, good sealing effect, erosion resistance and corrosion;
5, Applicable temperature is high, and pressure medium is large.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the utility model structural representation;
Numeral and the corresponding part title represented by letter in figure:
10, valve gap 20, valve body 30, cylinder 40, flap 41, mounting groove 42, flap spell cap 50, valve rod 60, seal ring 70, stuffing box 71, filler 80, support 81, bolt 82, nut 90, sealing surface 100, cemented carbide.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
Shown in Figure 1, the utility model discloses a kind of pneumatic fast shut-off stop valve, comprise valve gap 10, valve body 20, cylinder 30, flap 40 and the valve rod 50 for driving described flap to move, flap 40 is arranged in valve body chamber; Flap 40 is provided with a mounting groove 41, and one end of valve rod 50 is spelled cap 42 by flap and is arranged in the mounting groove 41 of flap 40, and the other end of valve rod 50 is connected with cylinder 30, and during work, cylinder 30 is with ovable valve stem 50 to rotate, and valve rod 50 drives flap 40 to rotate; Be provided with seal ring 60 between valve gap 10 and valve body 20, the top of valve gap 10 is provided with stuffing box 70, and stuffing box 70 is built with filler 71; Compressed by support 80 between valve gap 10 and valve body 20, be connected by bolt 81 between support 80 with valve body 20, fix finally by nut 82.
The utility model cylinder 30 is arranged on the top of support 80, is bolted between the two, and it is convenient to installation and removal.
The utility model valve body 20 is provided with multiple reserving installation hole, and each reserving installation hole is all provided with valve seat, valve rod and spool, and multiple reserving installation hole is linearly arranged; Concrete, the specification of multiple reserving installation hole can be identical or different, and preferably, the specification of multiple reserving installation hole is different, stimulates the menstrual flow to be applicable to different circulations.
The utility model is arranged with swelling spring on valve rod 50, and one end of swelling spring is connected with flap, and the other end is connected with valve gap; By the effect of swelling spring, flap can be made to be subject to a downward elastic force, thus to make to only have when the pressure of fluid is greater than hydrodynamic pressure in outlet passage in inlet passage, valve just source in the state opened; And the pressure of fluid is less than or equal to hydrodynamic pressure in outlet passage in inlet passage, valve then can carry out self closing, thus realize the backflow better preventing fluid in outlet passage.
Sealing surface 90 between the utility model flap 40 and valve body 20 is taper, conical seal (contact) face makes surface of contact narrow, this be sealed in certain sealing force effect under, its seal pressure increases greatly, easily reach better sealing effect, under the prerequisite ensureing sealing, compare with plane sealing, the sealing force applied is less; At sealing surface 90 place pile-up welding hard alloy 100, add the use specific pressure of sealing surface place material, erosion resistance and corrosion; From selection and structure, this valve can adapt to the requirement of higher temperature and pressure; Operationally medium is less to the erosion of valve seal material, corrosion and effect of attrition, can ensure that valve does not ooze within the spreadable life (letting out) dew, longer service life.
The utility model filler is made up of teflon, guarantees without inside and outside leakage, corrosion-resistant, the advantages such as long service life.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
