Abstract
The utility model discloses a novel waterproof hammer coaxial valve. The novel waterproof hammer coaxial valve comprises a valve body, wherein a piston and piston rod assembly is arranged in the valve body, an inner through hole is formed in the piston and piston rod assembly, a medium inflows from one end of the inner through hole, a sealing assembly is arranged at the other end of the inner through hole, the sealing assembly and the piston and piston rod assembly are coaxially arranged, and the sealing assembly is composed of a sealing gasket, a supporting ring and a spring. The novel waterproof hammer coaxial valve has the advantages that high pressure can be borne due to the pressure-difference-free design; impurities can be prevented due to the fact that the primary seal is the linear seal; the boundary dimension is small due to the coaxial design, and no large space needs to be occupied in the installation process.
Description
Technical field
The utility model relates to valve technology field, is specifically related to a kind of new waterproof hammer coaxial valve.
Background technique
" water hammer effect " refers at water pipe inner, and inner tube wall is smooth, and water flow freely.When the valve of opening is closed suddenly, current, to valve and tube wall, are mainly that valve can produce a pressure.Because tube wall is smooth, follow-up current, under the effect of inertia, reach rapidly maximum, and produce destruction, " water hammer effect " in the middle of Here it is hydro science, namely positive water hammer.In water pipeline construction, all to consider this factor.On the contrary, the valve of closing, after throwing open, also can produce water hammer, is negative water hammer, also has certain collapsing force, but large less than the former.
There is following shortcoming in the existing valve addressing the above problem: 1. function singleness: can only realize water hammer-resistant effect, there is no switch valve function; 2. requirements of installation space is large; 3. not high pressure resistant: above product pressure is all below 3MPa; 4. not resistance to impurity: water hammer receives G&W hammer to eliminate valve can to damage very soon when conveying has the medium of impurity.
Summary of the invention
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of new waterproof hammer coaxial valve is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of new waterproof hammer coaxial valve described in the utility model, comprise valve body, in valve body, be provided with piston, piston rod assembly, described piston, piston rod assembly are provided with inner via hole, medium flows into from one end of inner via hole, the other end of inner via hole is provided with black box, and described black box and piston, piston rod assembly coaxially arrange, and black box is comprised of sealing gasket, support ring and spring.
As preferably, described spring one end is arranged in valve body inner chamber groove, and one end is connected with support ring, and the other end center of support ring is provided with interior threaded hole, and sealing gasket is fixed on support ring by screw rod, is also provided with medium through hole on support ring.
As preferably, described spring is butterfly spring.
As preferably, described spring is heavy-duty springs.
As preferably, described piston, piston rod assembly are by compressed air-driven.
Adopt after said structure, the utility model beneficial effect is: owing to adopting the design of zero pressure difference formula, therefore can bear high pressure; Because primary seal is linear sealing, therefore can resistance to impurity; Owing to adopting coaxial-type design, therefore boundary dimension is little, during installation, do not take larger space.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical solution of the utility model, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is that the utility model is opened shape body structure schematic diagram;
Fig. 2 is the utility model closed condition structural representation.
In figure: 1, valve body, 2, piston, piston rod assembly, 3, inner via hole, 4, sealing gasket, 5, support ring, 6, spring, 7, medium through hole.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As Fig. 1, shown in Fig. 2, a kind of new waterproof hammer coaxial valve, comprise valve body 1, in valve body 1, be provided with piston, piston rod assembly 3, described piston, piston rod assembly 3 is provided with inner via hole 4, medium flows into from one end of inner via hole 3, the other end of inner via hole is provided with black box, described black box and piston, piston rod assembly 2 coaxially arranges, black box 2 is by sealing gasket 4, support ring 5 and spring 6 form, spring 6 one end are arranged in valve body 1 inner chamber groove, one end is connected with support ring 5, the other end of support ring 5 is provided with interior threaded hole by center, sealing gasket 4 is fixed on support ring 5 by screw rod, on support ring 7, be also provided with medium through hole 7, spring 6 can be butterfly spring, also can be heavy-duty springs, piston, piston rod assembly 2 is by compressed air-driven.
As shown in Figure 1, when the utility model is during in open mode, medium is flowed into by left end, the inner via hole 3 of process piston, piston rod assembly 2 and sealing gasket 4, support ring 5 assemblies are flowed out by right-hand member, the commutation of valve is realized by compressed air-driven piston, piston rod assembly 2, primary seal is realized by piston rod and sealing gasket 4, support ring 5 assemblies, owing to adopting the design of zero pressure difference formula, therefore can bear high pressure; Because primary seal is linear sealing, therefore can resistance to impurity.Owing to adopting coaxial-type design, therefore boundary dimension is little, during installation, do not take larger space.
As shown in Figure 2, when the utility model is during in closed condition, due to closing velocity be exceedingly fast (50ms), medium in piston rod inside and left end pipeline is because inertia is to sealing gasket 4, it is water hammer effect that support ring 5 assemblies produce larger impact, sealing gasket 4, support ring 5 assemblies butterfly spring is below by compressed, sealing gasket 4, support ring 5 assemblies will move right under the effect of water hammer, at this moment piston rod and sealing gasket are thrown off, form a less gap, the pressure off-load that forms water hammer is fallen, because pressure medium after pressure release reduces, support ring 5 will be moved to the left under the effect of butterfly spring in the back, again contact with piston rod, medium-tight is lived, thereby realized the effect of water hammer-resistant.
The above, it is only preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, although the utility model discloses as above with preferred embodiment, yet not in order to limit the utility model, any those skilled in the art, do not departing within the scope of technical solutions of the utility model, when can utilizing the technology contents of above-mentioned announcement to make a little change or being modified to the equivalent embodiment of equivalent variations, in every case be the content that does not depart from technical solutions of the utility model, any simple modification of above embodiment being done according to technical spirit of the present utility model, equivalent variations and modification, all still belong in the scope of technical solutions of the utility model.
