Abstract
The utility model three-way cut-off valve, it is made up of valve body, valve gap, valve rod, sealing gasket, clamping cap, handwheel, nut etc.; Described valve body is provided with a medium inlet passage, two medium flow pass, flowing medium can be provided for two pipelines; The flap design globulate of described stem lower portion, can reduce flow resistance and the particle avoiding clamping flowing medium; Valve seat on described valve body is arranged to taper, forms sealing pair with spherical flap, increases sealability, Leakage prevention.
Description
Technical field
The utility model relates to a kind of stop valve, especially a kind of three-way cut-off valve.
Background technique
Stop valve, because its adjusting function is better, Lift is little, shut-in time is short, manufacture and maintenance is convenient, and sealing surface is not easy to wear, scratch, the features such as sealability is better, long service life, all being widely used in multiple fields such as petrochemical industry, electric power, metallurgy, urban construction, chemical industry, is be applied to one of the widest valve.But the stop valve used at present also exists the shortcomings such as the particle may clamped between sealing surface in flowing medium, flow resistance are larger; In addition, common stop valve only has an outlet, cannot provide fluid for many pipelines.
Summary of the invention
Technical problem to be solved in the utility model be provide for the above-mentioned state of the art a kind of not easily clamp granule foreign, flow resistance little, have two three-way cut-off valves exported.
The utility model solves the problems of the technologies described above adopted technological scheme: three-way cut-off valve, and it is made up of valve body, valve gap, valve rod, sealing gasket, clamping cap, handwheel, nut etc.; Described valve body is provided with the connection chamber of a medium inlet passage, two medium flow pass and connecting media inlet passage and medium flow pass, in connection chamber, is provided with valve seat; Described valve gap is threaded and is fixed on valve body top; Described valve rod runs through valve gap, and stem lower portion is provided with flap, and valve rod top passes valve gap and is connected with handwheel, fixes with nut; It is characterized in that being sealed by clamping cap compression seal pad between described valve gap and valve rod.
As improvement, the flap design globulate of described stem lower portion, can reduce flow resistance and the particle avoiding clamping flowing medium; Valve seat on described valve body is arranged to taper, forms sealing pair with spherical flap, increases sealability, Leakage prevention.
Compared with prior art, the utility model has the advantage of: described valve body is provided with a medium inlet passage, two medium flow pass, flowing medium can be provided for two pipelines; The flap design globulate of described stem lower portion, can reduce flow resistance and the particle avoiding clamping flowing medium; Valve seat on described valve body is arranged to taper, forms sealing pair with spherical flap, increases sealability, Leakage prevention.

Fig. 1 is plan view structural representation of the present utility model.
Fig. 2 is plan view structural representation of the present utility model.
Fig. 3 is left view structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in the figure, three-way cut-off valve, it is made up of valve body 1, valve gap 2, valve rod 3, sealing gasket 4, clamping cap 5, handwheel 6, nut 7 etc.; Described valve body 1 is provided with the connection chamber of a medium inlet passage 8, two medium flow pass 9,10 and connecting media inlet passage 8 and medium flow pass 9,10, in connection chamber, is provided with valve seat 11; Described valve gap 2 is threaded and is fixed on valve body 1 top; Described valve rod 3 runs through valve gap 2, and valve rod 3 bottom is provided with flap 12, and valve rod 3 top passes valve gap 2 and is connected with handwheel 6; Fix with nut 7 between described valve rod 3 and handwheel 6; It is characterized in that being sealed by clamping cap 5 compression seal pad 4 between described valve gap 2 and valve rod 3.The flap 12 of described valve rod 3 bottom is designed to spherical, can reduce flow resistance and the particle avoiding clamping flowing medium; Valve seat 11 on described valve body 1 is arranged to taper, forms sealing pair with spherical flap 12, increases sealability, Leakage prevention.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
