Description
Technical field:
The utility model relates to a kind of stop valve, particularly relates to a kind of novel cutoff valve.
Background technique:
The valve of stop valve to be a kind of open-shut device be flap, drives flap to move up and down the keying of moving valve by valve rod, is highly suitable for cutting off or regulating pipeline fluid, producing and having a wide range of applications in pipeline in life.In existing mud, sandstone pipeline, when flap is closed, ducted solid granule is very easily mixed in the surface of contact of valve rod and flap, causes occurring between valve rod and flap stuck or loosening, have impact on the normal operation of whole valve, bring many inconvenience to user.
Model utility content:
For the deficiency of above-mentioned technology, the utility model devises a kind of novel cutoff valve, and by valve body, flap, valve rod, contiguous block, sealing plate, flap cap form.
The technical solution adopted for the present invention to solve the technical problems is: be provided with flow channel and flow pass in valve body, valve body is provided with circumferential notch at flow channel and flow pass jointing place, circumferential notch is provided with flap, described flap is " recessed " word structure, flap comprises contiguous block and sealing plate, described contiguous block is hollow cylindrical, and the bottom of contiguous block inwall is provided with screw thread, and screw thread connects valve rod; Sealing plate is filled circles column, and sealing plate is arranged on below contiguous block, sealing plate with contiguous block by disposable machine shaping, sealing plate diameter be 0.8 times of contiguous block diameter; Valve rod with the surface of contact of contiguous block on be provided with flap and cap, described flap cap by and cap body and protecting sheet form, and cap body is hollow cylindrical, and cap body is looped around around valve rod, and 1.1 times of the chi footpath of cap body and valve rod chi footpath; And cap body is provided with protecting sheet; protecting sheet is circular; protecting sheet is fixed on the top of flap contiguous block; the outside diameter of protecting sheet is 1.2 times of circular diameter in flap contiguous block; effectively prevent solid particle from slipping on the surface of contact of valve rod and flap, cause between valve rod and flap stuck or loosening.
The beneficial effects of the utility model: prevent between valve rod and flap stuck or loosening.
Accompanying drawing illustrates:
Fig. 1 is main TV structure figure of the present utility model;
Wherein, 1-valve body, 2-flap, 3-valve rod, 4-contiguous block, 5-sealing plate, 6-flap cap.
Embodiment:
The utility model devises a kind of novel cutoff valve, by valve body, flap, valve rod, contiguous block, sealing plate, flap cap form, flow channel and flow pass is provided with in valve body, valve body is provided with circumferential notch at flow channel and flow pass jointing place, and circumferential notch is provided with flap, and described flap is " recessed " word structure, flap comprises contiguous block and sealing plate, described contiguous block is hollow cylindrical, and the bottom of contiguous block inwall is provided with screw thread, and screw thread connects valve rod; Sealing plate is filled circles column, and sealing plate is arranged on below contiguous block, sealing plate with contiguous block by disposable machine shaping, sealing plate diameter be 0.8 times of contiguous block diameter; Valve rod with the surface of contact of contiguous block on be provided with flap and cap, described flap cap by and cap body and protecting sheet form, and cap body is hollow cylindrical, and cap body is looped around around valve rod, and the chi footpath of cap body is 1.1 times of valve rod chi footpath; And cap body is provided with protecting sheet; protecting sheet is circular; protecting sheet is fixed on the top of flap contiguous block; the outside diameter of protecting sheet is 1.2 times of circular diameter in flap contiguous block; effectively prevent solid particle from slipping on the surface of contact of valve rod and flap, solve problem stuck or loosening between valve rod and flap.
