Abstract
The utility model discloses a material transfer valve of valve gap area disk seat protective sheath, metal protection cover, the ceramic disk seat of solving the material transfer valve that there has been disk seat area L shape protective sheath are easy to be not hard up with the valve gap, cause wearing and tearing, and be sealed not tight, the problem of life weak point. The centre bore of valve gap (4) is the straight hole, the terminal surface has the cross -section to be ring channel (8) of L shape under it, the upward bottom of ring channel is narrow, the lower part is wide, pottery disk seat (9) is the ring of cross -section for L shape, pottery disk seat upper portion is wide, the lower part is narrow, the lower terminal surface of valve gap (4), the lower terminal surface of pottery disk seat (9), the lower terminal surface of metal clamping ring (6) is at the coplanar, equal height in pottery disk seat (9) and ring channel (8) and internal diameter between them are equal, the lower part of ring channel (8), the lower part of pottery disk seat (9), metal clamping ring (6) etc. Are high, the external diameter of metal clamping ring (6) and the big external diameter movable fit of the ring channel 8 of L shape, the internal diameter of metal clamping ring and the little external diameter movable fit of ceramic disk seat (9), pottery disk seat (9) is packed into and is linked firmly on valve gap (4) through screw (10) with metal clamping ring (6) behind the ring channel of valve gap.
Description
technical field:
The valve in the ash transfer storehouse pump in the utility model and thermal power plant, pipeline and grey storehouse is relevant, especially relevant with mass transport valve.
background technique:
Existing mass transport valve; valve body is connected with valve cover bolt; the lower end of rotating shaft and one end of pivoted arm are connected; the other end of pivoted arm is connected with valve plate; ceramic valve seat on valve plate and valve gap is sealed and matched, and the cross section of ceramic valve seat and metal protection protector is all L shape, and the center hole of valve gap is step hole; ceramic valve seat is connected with metal protection protector, is connected on the step of the center hole of valve gap with metal trim ring by screw.Although solve the protection problem of valve seat; but protecting jacket and valve seat combination are integrated; complex structure; cost is higher, and metal protection protector, ceramic valve seat only have screw to be connected with the step of the center hole of valve gap, and junction surface is large and without clamping; metal protection protector, ceramic valve seat are easy and valve gap is loosening; cause wearing and tearing, poorly sealed, working life is short.
model utility content:
The purpose of this utility model is to provide that a kind of structure is simple, easy installation and removal, ceramic valve seat are not hit destructions, sealing reliably, the mass transport valve of the valve gap band valve seat protecting jacket of long service life.
The utility model is achieved in that
The mass transport valve of valve gap band valve seat protecting jacket, valve body 1 is connected with bolt with valve gap 4, the lower end of rotating shaft 5 and one end of pivoted arm 2 are connected, the other end of pivoted arm is connected with valve plate 3, ceramic valve seat 9 on valve plate and valve gap 4 is sealed and matched, the center hole of valve gap 4 is straight hole, its lower end surface has cross section to be the circular groove 8 of L shape, the upper bottom portion of circular groove is narrow, bottom is wide, ceramic valve seat 9 for cross section be the annulus of L shape, ceramic valve seat top is wide, bottom is narrow, the lower end surface of valve gap 4, the lower end surface of ceramic valve seat 9, the lower end surface of metal trim ring 6 is at same plane, ceramic valve seat 9 and circular groove 8 is contour and both internal diameter is equal, the bottom of circular groove 8, the bottom of ceramic valve seat 9, metal trim ring 6 is contour, the external diameter of metal trim ring 6 coordinates with the large external diameter in bottom of the circular groove 8 of L shape is dynamic, the internal diameter of metal trim ring coordinates with the little external diameter in the bottom of ceramic valve seat 9 is dynamic, be connected on valve gap 4 by screw 10 with metal trim ring 6 after ceramic valve seat 9 loads the circular groove of valve gap.
The utility model has the following advantages:
1) after ceramic valve seat 9 loads the circular groove 8 of valve gap; be connected on valve gap 4 with metal trim ring 6 by screw 10; ceramic valve seat is equivalent to protect with the metal protection protector with valve gap 4 one; due to the steadiness of valve gap 4, under the collision of medium and foreign matter, can not loosen with the metal protection protector of valve gap 4 one; can not be damaged; thus carry the working life and sealability of having done valve, in use can not produce interior leakage and leak outside, pulverized fuel ash can not be caused the pollution of atmosphere environment.The utility model and the comparative trial of background technique prove that the utility model improves more than 2 years than the technological scheme of background technique working life.
2) circular groove 8 of valve gap is as protecting jacket, and structure is simple, manufactures, mounts and dismounts conveniently.
3) ceramic valve seat Long-Time Service is not shifted or departs from, and does not need frequent maintenance, and sealing is reliable, uses nothing more than 5 years to damage, receives praises from customers.
accompanying drawing illustrates:
Fig. 1 is structural drawing of the present utility model.
embodiment:
The mass transport valve of valve gap band valve seat protecting jacket, valve body 1 is connected with bolt with valve gap 4, the lower end of rotating shaft 5 and one end of pivoted arm 2 are connected, the other end of pivoted arm is connected with valve plate 3, ceramic valve seat 9 on valve plate and valve gap 4 is sealed and matched, the center hole of valve gap 4 is straight hole, its lower end surface has cross section to be the circular groove 8 of L shape, the upper bottom portion of circular groove is narrow, bottom is wide, ceramic valve seat 9 for cross section be the annulus of L shape, ceramic valve seat top is wide, bottom is narrow, the lower end surface of valve gap 4, the lower end surface of ceramic valve seat 9, the lower end surface of metal trim ring 6 is at same plane, ceramic valve seat 9 and circular groove 8 is contour and both internal diameter is equal, the bottom of circular groove 8, the bottom of ceramic valve seat 9, metal trim ring 6 is contour, the external diameter of metal trim ring 6 coordinates with the large external diameter in bottom of the circular groove 8 of L shape is dynamic, the internal diameter of metal trim ring coordinates with the little external diameter in the bottom of ceramic valve seat 9 is dynamic, be connected on valve gap 4 by screw 10 with metal trim ring 6 after ceramic valve seat 9 loads the circular groove of valve gap.
