Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1-2 is referred to, the utility model provides a kind of technical scheme：A kind of novel manual flat gate valve, including valve body
1st, valve seat 3, valve rod 7, bonnet 9 and valve bonnet 21, valve seat 3 are seated at the bottom centre of valve body 1, and the bottom of valve seat 3 is connected by guide plate 2
Valve body 1 is connect, the top of valve seat 3 is provided with flashboard 6 and valve rod 7, and valve rod 7 is threadedly coupled valve stem nut 18, bonnet 9 through bonnet 9
Valve body 1 is tightly connected by mesopore sealing ring 8；Condiment gland 14, condiment gland 14 are provided between valve stem nut 18 and bonnet 9
Bottom is provided with valve stem packing 11, and valve stem nut 18 is fixedly connected with support 15 by bearing 16, and the outer top of valve stem nut 18 is set
Handwheel 19 and valve bonnet 21 are equipped with, the junction of handwheel 19 and valve stem nut 18 is provided with handwheel direction board 20.
Support 15 connects bonnet 9 by tight fixed bolt 13, is fixedly connected between bonnet 9 and valve body 1 by bolt 12；Bonnet
Grease pouring valve 10 is provided among 9；The side of support 15 is provided with lubricating cup 17；Valve seat 3 and the junction of valve body 1 are provided with some O-rings
4, valve seat 3 is internally provided with some wavy springs 5；Nameplate 22 is provided with the side wall of valve body 1, nameplate 22 is fixedly connected by rivet
Valve body 1.
Operation principle：This valve leans on being freely bonded between metal flashboard 6 and the plane of metal seat valve 2, by stop-leak compound
And sealing is realized in the presence of medium, whenever all fertilizer bears line pressure in valve pocket.Bonnet 9 and valve body 1 use spiral shell
Tether and connect, seal is pressure enhanced gasket ring, and it makes the fit-up gap very little of bonnet 9 and valve body 1, and this reduces corrosion to be situated between
The erosion of confrontation bolt 12 and screw.The gate valve can be rising stem (RS.) structure, and the screw thread of valve rod 7 independent can obtain from the erosion of medium
To lubrication.Flashboard 6 and the surface spraying weld hard alloy of valve seat 2, with good wearability and corrosion resistance, the material of valve rod 7
Material uses anti-sulphur steel, and other parts are using the method for limiting hardness, thus the valve can use in the environment containing H2S.And root
Can be all using stainless steel making according to needs.Condiment gland 14 is provided with the lubricating cup 17 for being used for lubricating bearing 16, is easy to live supplement
Lubricating grease.There is lubrication oil discharge hole lower section, and can observe lubricant grease has filling situation.May also function as seepage effect, so as to
Medium is discharged into air by the lip type packing of valve rod 7 when leaking, and these three apertures are usually covered with O-ring, is entered to prevent foul.Valve
The elevating screw thread of bar 7 uses left-handed trapezoidal thread, is clockwise "Off", is counterclockwise "ON", with being accustomed to unanimously.Inverse time
Pin rotation hand wheel 19, until the back seal of valve rod 7 in place, now gate valve is fully open, then rotate clockwise handwheel 191/4-
1/2 circle.Handwheel 19 turn clockwise until flashboard 6 withstands the bottom of valve body 1, now gate valve completely closes, and then rotates counterclockwise
Handwheel 191/4-1/2 encloses.3.3 because flashboard 6 is the closing moved along channel centerline vertical direction, only plays cut-out passage
Effect, thus the valve cannot function as choke valve use, i.e. the working condition of flashboard 6 only has two positions, standard-sized sheet or fully closed, not allowed
Open part.Because flashboard 6 is flowing down by realization sealing of floating on valve seat, thus flashboard 6 can not be stuck, that is, closes necessary in place
The circle of reversion 1/4-1/2.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
