Description
Technical field
This utility model is related to a kind of on-line cleaning sealing surface flat gate valve, belongs to valve field.
Background technology
Flat gate valve is that a kind of dependence valve rod drives flashboard up and down motion to reach valve opening and close the equipment of purpose.When
Valve is made valve seal bad and valve opening is difficult using the dirt that bonds is easy on the sealing surface in impure pipeline.
Utility model content
The purpose of this utility model is to provide a kind of on-line cleaning sealing surface flat gate valve, to solve the above problems.
This utility model employs following technical scheme：
A kind of on-line cleaning sealing surface flat gate valve, it is characterised in that include：Shell, the bottom of shell is valve body；Lock
Plate, is arranged on the central authorities of valve inner；Valve rod, is arranged on the top of flashboard, drives ram movement；Valve seat, is arranged in valve body,
And it is enclosed within around flashboard；Sealing ring, is arranged on the position of valve seat and valve body contact；Pincerlike watering trough, is arranged on sealing ring
Periphery, the opening of pincerlike watering trough towards sealing ring, filled with scouring media in pincerlike watering trough.
Further, on-line cleaning sealing surface flat gate valve of the invention, can also have the feature that, also have：Note
Water hole, is connected with pincerlike watering trough.
Further, on-line cleaning sealing surface flat gate valve of the invention, can also have the feature that, also have：Under
Flushing pollution discharge hole, discharges the dirt for being swept away to come by pincerlike watering trough.
Further, on-line cleaning sealing surface flat gate valve of the invention, can also have the feature that：Wherein, shell
Also include：Valve gap and support, valve gap are arranged on above valve body, and support is arranged on above valve gap.
Further, on-line cleaning sealing surface flat gate valve of the invention, can also have the feature that：Wherein, valve body
It is fixedly connected using the first bolt with valve gap.
Further, on-line cleaning sealing surface flat gate valve of the invention, can also have the feature that：Wherein, valve gap

Make the time.
Description of the drawings
Fig. 1 is the half-sectional view of on-line cleaning sealing surface flat gate valve of the present utility model；
Fig. 2 is the partial enlarged drawing of a-quadrant in Fig. 1；
Fig. 3 is the enlarged diagram in B regions in Fig. 2.
Specific embodiment
The specific embodiment of the present invention is illustrated below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, on-line cleaning sealing surface flat gate valve includes：Valve body 1, flushing pollution discharge hole 2, valve seat 3, on
Sealing ring 4, lower seal 41, flashboard 5, valve rod 6, pincerlike watering trough 7, the first bolt 8, valve gap 9, middle flange seal gasket 12,
Second bolt 13, water injection hole 15.
Shell includes：By to the valve body 1, valve gap 9 and support 11 being above sequentially connected.
Valve body 1, is arranged on periphery, protects internal structure.
Valve seat 3, is arranged on around flashboard 5.
Flashboard 5, is vertically arranged on valve seat 3, and valve rod 6 drives flashboard 5 to move.
Upper sealing ring 4 and lower seal 41, be separately positioned on valve seat 3 and valve body are vertically connected with place.
Pincerlike watering trough 7, is arranged on the periphery of sealing ring 4, as shown in figure 3, the opening of pincerlike watering trough 7 is against upper close
The side of seal 4,7 points of both sides of pincerlike watering trough are fixed on sealing surface both sides, outside flashboard switching range, avoid dry with flashboard
Relate to.
First bolt 8, valve gap 9 and valve body 1 are fixed together.
Support 11 and valve gap 9 are linked together using the second bolt 13.
Middle flange seal gasket 12 is arranged on the junction of support 11 and valve gap 9.
Flushing pollution discharge hole 2, the dirt that pincerlike watering trough 7 is rinsed are discharged from inside valve.Water injection hole 15 and pincerlike spray
Tank 7 is connected.Water injection hole 15 and 2 one, flushing pollution discharge hole tap into one connected water outlet pipe of water pipe.When being rinsed to valve, punching
Wash medium to enter in pincerlike watering trough 7 from water inlet pipe, sealing surface is rinsed, then sewage is discharged from outlet pipe.
Therefore when sealing surface needs cleaning, it is not necessary to take valve apart, can be rinsed with direct-on-line, flush efficiency is high, section
The operating time is saved.
