Abstract
The utility model provides an inner-expand sealing-gate-plate type valve, which is used for conveying the fluid and the slurry of the pipeline and equipment. The improvement is that a valve plate component 8 is provided with a wear resisting ring 9 and a wear resisting ring 15. An inlet flange 5 is provided with a sealing ring 14 with rigidity and wear resistance. When the valve is in the closing state, the sealing ring 14 is positioned between the wear resisting ring 9 and the wear resisting ring 15. The contact surface of the valve plate component 8 and a positioning component 1 and the axial direction of a flange flowing path are provided with a tilt angle. A screw rod 10 is not contacted with the fluid and the slurry. An inner lining of the flowing path is a wear resisting layer 2 made of cast stone. The utility model has the advantages of tight sealing, convenient closing, no corrosion on the screw rod, wear resistance on the flowing path, etc.
Description
The utility model relates to a kind of gate valve, particularly internal expanding sealing-gate-board type valve that is used for industrial pipeline and establishes fluid and slurry feed adjustment flow.
Known internal expanding sealing-gate-board type valve, employing be flexible seals, when valve is in throttle and in opening process, the washing away of granular material that sealing surface is subjected in fluid and the slurry caused uneven wear, makes valve seal not tight.Next deficiency of known valve is the parallel axes of the surface of contact and the runner of valve plate locating piece and valve board assembly, and like this in the valve closing process, the frictional force of this surface of contact is bigger, valve close effort; Known valve deficiency is also that the fluid in valve screw rod and the valve housing contacts with slurry and causes corrosion; The deficiency of known valve is that also the washing away of granular material that its runner is subjected in fluid and the slurry cause wearing and tearing.
The purpose of this utility model is to provide a kind of internal expanding sealing-gate-board type valve, to overcome the deficiency of above-mentioned valve.
The utility model is to realize like this, it has valve plate lifting opening/closing mechanism, valve housing 6, valve board assembly 3, valve board assembly 8, valve plate locating piece 1, inlet flange 5 and outlet(discharge) flange 4, its improvements are to have wear ring 9 and wear ring 15 on the valve board assembly 8, has rigidity wear-resistant seal ring 14 on the inlet flange 5, when valve was in closed condition, rigidity wear-resistant seal ring 14 was between wear ring 9 and wear ring 15.
The utility model internal expanding sealing-gate-board type valve, can be the surface of contact of valve plate locating piece 1 and valve board assembly 8 and flange 5, flange 4 runner axially have a tilt angle.
The utility model internal expanding sealing-gate-board type valve can be that valve board assembly 3 is fixedlyed connected with guide pin bushing 7, and guide pin bushing 7 matches with screw rod 10.
The utility model internal expanding sealing-gate-board type valve can be that wear ring 9 and wear ring 15 are cast stone wear rings.
The utility model internal expanding sealing-gate-board type valve can be that rigidity wear-resistant seal ring 14 is abrasion resistance alloy seal rings.
The utility model internal expanding sealing-gate-board type valve can be the interior diabase lining wearing layer 2 of runner of inlet flange 5 and outlet(discharge) flange 4.
It is tight that the utility model internal expanding sealing-gate-board type valve has sealing, closes laborsavingly, and the valve screw rod does not corrode and advantages such as runner is wear-resisting.
Fig. 1: the sectional drawing of the utility model internal expanding sealing-gate-board type valve.
The partial enlarged drawing of Fig. 2: Fig. 1.
The utility model is described in further detail in conjunction with the embodiments with reference to accompanying drawing.
The utility model internal expanding sealing-gate-board type valve, it has the valve plate lifting opening/closing mechanism that is made of handwheel 13, screw rod flange 12, cover for seat 11, screw rod 10 and the guide pin bushing 7 that matches with it, valve housing 6, guide pin bushing 7 is fixedlyed connected with valve board assembly 3, have wear ring 9 and wear ring 15 on the valve board assembly 8, has rigidity wear-resistant seal ring 14 on the inlet flange 5, when valve is in closed condition, seal ring 14 is between wear ring 9 and wear ring 15, wear ring 9 and wear ring 15 are cast stone wear rings, and rigidity wear-resistant seal ring 14 is abrasion resistance alloy seal rings.When valve is in throttle and at the opening process of valve, granule materials in fluid and the slurry can only have slight wearing and tearing to the sealing surface between wear ring 9 and the wear ring 15, sealing configuration provided by the utility model can be at valve and close the shape sealing sternly, does not leak.The runner of the surface of contact of valve plate locating piece 1 and valve board assembly 8 and flange 5, flange 4 axially have a tilt angle, between the pass of valve closed procedure valve board assembly 8 and valve plate locating piece 1 friction very little, close laborsaving.Screw rod 10 matches with guide pin bushing 7, screw rod 10 not with housing 6 in fluid contact with slurry, do not corrode screw rod.Diabase lining wearing layer 2 in the runner of flange 5 and flange 4, runner is wear-resisting.
Claims (6)
