Description
Technical field
The utility model relates to a kind of plate valve, especially relates to a kind of plate valve for dilute phase pneumatic conveying.
Background technique
Gate valve is generally used for the media flow of opening or blinding off a line, and open-shut device is flashboard, and moving direction and the flow direction of flashboard are perpendicular.Gate valve can only be used as standard-sized sheet and complete shut-down, can not make adjustments and use with throttling.The wherein slide-valve of plate valve to be a kind of closure member be parallel gate plate.Its closure member can be Single disc or therebetween with the double-flashboard of spreading mechanism.The advantage of plate valve is that body is simple, structure length is short, resistance is little, MEDIA FLOW is to unrestricted, not disturbance; Shortcoming easily causes erosion and scratch between sealing surface, and maintenance difficult, especially when seat bottom portion accumulates foreign material, flashboard is not closed completely.Outside screw stem rising through handwheel type gate valve is opened needs larger space.Standard-sized sheet, full cut-off need the long period.In addition, when gate valve is used in Geldart-D particle, especially dilute phase pneumatic conveying, the particle packing of body base groove during gate valve standard-sized sheet, body base groove walls surface wear are all very serious.
Therefore, the working principle of research dilute phase pneumatic conveying middle plateform gate valve and vibrational power flow, when preventing gate valve standard-sized sheet body base groove particle packing, prevent the wearing and tearing of body base groove wall, extremely important to sealability when improving the working life of gate valve and close.
Model utility content
Overcome the defect of existing dilute phase pneumatic conveying middle plateform gate valve, the purpose of this utility model is to provide a kind of plate valve for dilute phase pneumatic conveying, reduces the wearing and tearing of plate valve groove, improves the working life of gate valve.
The technical solution adopted in the utility model is:
The utility model comprises valve body, flashboard, valve rod, valve gap, guide sleeve, top cover, handwheel and Stem Mut; Valve body is built with flashboard, valve body upper end is equipped with valve gap and top cover successively, top cover is built with guide sleeve, one end of valve rod is connected with flashboard by Stem Mut, the other end of valve rod stretches out outside top cover through guide sleeve, the Stem Mut rotated on handwheel band ovable valve stem makes the flashboard of stem bottom move up and down, opening and closing gate valve.The utility model is also placed with spring in body base groove, place dull and stereotyped above spring, dull and stereotyped both sides, top have retaining groove, and the left and right sides, body base slot opening place is symmetrical is respectively welded with the identical welded plate of size, and the width of retaining groove is identical with length with the width of welded plate with length.
Described flat board is woodboard or plastic board.
The plank that dull and stereotyped material selection material is lighter or plastics.
The beneficial effect that the utility model has is:
By the understanding to pipeline dilute phase pneumatic conveying, in conjunction with particle packing principle and erosion of wall principle, solve plate valve some shortcomings in dilute phase pneumatic conveying.The utility model makes full use of the spring placed in valve body of flat gate valve bottom groove, flat board on spring, the welded plate that the symmetrical size be welded with is identical respectively along the left and right sides, medium circulating direction valve body of flat gate valve slot opening place, when plate valve standard-sized sheet, the original groove runner of gate valve becomes straight pipeline runner, prevents inside grooves from having particle packing and the wearing and tearing that particles collision gate valve body groove wall produces occur; When plate valve is closed, by the elastic force of spring action on flashboard, strengthen the sealability of plate valve; When Stem Mut lost efficacy, due to spring and dull and stereotyped effect, the bottom portion of groove of plate valve can not be subject to serious flashboard and impact, but a process slowly declined.
The utility model can meet the demand in the field such as gas conveying, dilute phase pneumatic conveying being mingled with a small amount of impurity.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the utility model comprises valve body 1, flashboard 5, valve rod 6, flange 7, screw 8, valve gap 9, " O " shape seal ring 10, guide sleeve 11, top cover 12, handwheel 13 and Stem Mut 14; Valve body 1 is built with flashboard 5, valve body 1 upper end is connected by flange 7 screw 8 with valve gap 9 lower end, valve gap 9 upper end is also connected with screw with top cover 12 lower end, top cover 12 is built with guide sleeve 11, one end of valve rod 6 is connected with flashboard 5 by Stem Mut 14, the other end of valve rod 6 stretches out outside top cover 12 through guide sleeve 11, rotating handwheel 13 makes the flashboard 5 bottom valve rod 6 move up and down with the Stem Mut 14 on ovable valve stem 6, opening and closing gate valve, top cover 12 is contained in the pressure that handwheel 13 bottom is used for increasing " O " shape seal ring 10.The utility model is also placed with spring 2 in body base groove 16, spring 2 places dull and stereotyped 3 above, dull and stereotyped 3 both sides, top have retaining groove 17, the body base groove 16 opening left and right sides is symmetrical is respectively welded with the identical welded plate of size 4, and the width of retaining groove 17 is identical with length with the width of welded plate 4 with length.
Spring 2 and dull and stereotyped 3, can directly be placed in gate valve body bottom groove 16, also can fix as a whole by spring 2 and dull and stereotyped 3 by bonding method.Be welded with the identical welded plate of size by the gate valve body bottom groove opening left and right sides is symmetrical respectively, overcome the elastic force of spring, spring 2 and dull and stereotyped 3 are squeezed in gate valve body bottom groove.The retaining groove 17 of dull and stereotyped 3 both sides is to match with welded plate 4, excises that the width of one piece of width and length and welded plate 4 and length same material obtain from complete square plate.
Described dull and stereotyped 3 is woodboard or plastic board.
As shown in Figure 1 and Figure 2, when rotating handwheel 13, the Stem Mut 14 on valve rod 6, will carry out opening or closing motion by the flashboard 5 with the plate valve under ovable valve stem 6, controls the keying of plate valve.When plate valve is opened, the spring 2 placed in plate valve bottom groove 16, under the effect of spring 2 elastic force, the flat board 3 be positioned on spring 2 will be pushed open, make dull and stereotyped 3 to match with the plate valve groove body base 16 opening left and right sides welded plate 4 that the symmetrical size be welded with is identical respectively, use original groove runner to become straight pipeline instantaneously.When plate valve closes, the flashboard 5 of plate valve will extrude the flat board 3 be positioned on spring 2, and spring 2 acts on the elastic force of the flashboard 5 of plate valve, strengthens the sealability of plate valve.
working principle of the present utility model is:
When the flashboard 5 of plate valve is opened, the groove runner of original valve body of flat gate valve bottom groove 16 is become a straight pipeline, 15 substantially horizontals passed through for medium by the effect of spring 2 and dull and stereotyped 3; When the flashboard 5 of plate valve cuts out, by mutually extruding the sealability increasing plate valve.This plate valve for dilute phase pneumatic conveying, is intended to the erosion of wall prevented the particle packing in existing Geldart-D particle middle plateform gate valve body bottom groove 16 and valve body of flat gate valve bottom groove 16, and does not increase overweight external load to plate valve.
