Description
Technical field
The present invention relates to a kind of check-valves, in particular, he is related to a kind of sphere check-valves of pressure adjustable.
Background technology
Check-valves is the primary element that fluid controls engineering, and it plays determination flow of fluid side by preventing fluid countercurrent current
To, protect the effect of other fluid machineries and pipeline safety, it is widely used in oil, metallurgy, chemical industry, electric power, building, heat
The industries such as power, water process.Common sphere check-valves is constant due to the pre compressed magnitude of spring, so that the pretightning force of spring is constant, makes
Opening pressure into valve valve is constant, influences the use scope of valve.
The content of the invention
In order to solve the technical problem of the above, the present invention provides a kind of sphere check-valves of pressure adjustable, using rotatable
Adjusting nut, so as to adjust the pretightning force of spring, be applicable the different applying working conditions of check-valves, reasonable in design, sealing
Can be good.
To achieve the above object, the technical solution adopted in the present invention is as follows：
A kind of sphere check-valves of pressure adjustable, including valve body, sphere cylinder valve element, spring, deflector, side valve body, pad, tune
Section nut, it is characterised in that：The side valve body left end is connected with valve body right-hand member, and side valve body left end is provided with deflector, described to lead
Pad is respectively provided between stream plate and valve body and side valve body, deflector is built with sphere cylinder valve element, the sphere cylinder valve element
Sealing surface is formed with valve body middle part, guide post is provided with sphere cylinder valve element, and guide post is stepped into three-level, sphere cylinder
Valve element step and sphere cylinder valve element three-level ladder contacts guiding with deflector simultaneously, sphere cylinder valve element and deflector it
Between be equipped with compression spring and adjusting nut.
Connected using screw bolt and nut between the valve body and side valve body.
The gasket materials are soft graphite.
Used between the adjusting nut and deflector and be threadedly coupled.
By above-mentioned technical proposal, the beneficial effects of the invention are as follows：
The present invention utilizes rotatable adjusting nut, so that the pretightning force of spring is adjusted, good seal performance, applicable check-valves
Different applying working conditions, life of valve is long, can be widely applied to the exit of pump of the pipe networks such as cold water, hot water, industry and sanitary sewage.

Specific embodiment
Embodiments of the present invention is further illustrated below in conjunction with the accompanying drawings：
As shown in figure 1, the invention provides a kind of sphere check-valves of pressure adjustable, including side valve body 7, the left end of side valve body 7 with
The right-hand member of valve body 1 is connected by bolt 4 and nut 5, facilitates installation, the debugging of valve, maintenance；The left end of side valve body 7 is provided with water conservancy diversion
Plate 6, is respectively provided with pad 8 between deflector 6 and valve body 1 and side valve body 7, and pad 7 is flexible graphite material, enhancing valve
Sealing property；Deflector 6 forms sealing surface, sphere post built with sphere cylinder valve element 2, sphere cylinder valve element 2 with the middle part of valve body 1
Guide post 13 is provided with body valve element 2, and 13 one-tenth three-levels of guide post are stepped, sphere cylinder valve element step 11 and sphere post
Body valve element three-level ladder 12 contacts guiding with deflector 6 simultaneously, it is ensured that sealing does not misplace；Sphere cylinder valve element 2 and water conservancy diversion
Compression spring 3 and adjusting nut 14 are housed, using being threadedly coupled between adjusting nut 14 and deflector 6, rotation is adjusted between plate 6
Nut 14 adjusts its axial location on deflector 6 to adjust the pretightning force of spring 3, so that control valve Opening pressure, fits
For different operating modes.
Obviously, the above embodiment of the present invention is only intended to clearly illustrate example of the present invention, and is not right
The restriction of embodiments of the present invention.For those of ordinary skill in the field, may be used also on the basis of the above description
To make other changes in different forms.There is no need and unable to be exhaustive to all of implementation method.And these
Belong to obvious change that connotation of the invention extends out or variation still falls within protection scope of the present invention.
