Abstract
The invention provides a material conveying valve with a valve deck provided with a valve seat protective sleeve. The material conveying valve with the valve deck provided with the valve seat protective sleeve solves the problems that by the adoption of an existing material conveying valve with a valve seat provided with an L-shaped protective sleeve, the metal protective sleeve and the ceramic valve seat are prone to being loosely connected with the valve deck, wear is caused, seal is poor, and the service life of the existing material conveying valve is short. The central hole of the valve deck (4) is a straight hole. The lower end face of the valve deck (4) is an annular groove (8) with an L-shaped section, wherein the upper bottom of the annular groove is narrow, and the lower portion of the annular groove is wide. The section of the ceramic valve seat (9) is an L-shaped round ring. The upper portion of the ceramic valve seat is wide, and the lower portion of the ceramic valve seat is narrow. The lower end face of the valve deck (4), the lower end face of the ceramic valve seat (9) and the lower end face of a metal press ring (6) are located on the same plane. The ceramic valve seat (9) and the annular groove (8) are equal in height and inner diameter. The lower portion of the annular groove (8), the lower portion of the ceramic valve seat (9) and the metal press ring (6) are equal in height. The outer diameter of the metal press ring (6) is in movable fit with the large outer diameter of the L-shaped annular groove (8). The inner diameter of the metal press ring (6) is in movable fit with the small outer diameter of the ceramic valve seat (9). After being contained in the annular groove of the valve deck, the ceramic valve seat (9) is fixedly connected to the valve deck (4) through screws (10).
Description
technical field:
The valve in the ash transfer storehouse pump in the present invention 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.
summary of the invention:
The object of this invention is to provide that a kind of structure is simple, easy installation and removal, ceramic valve seat be not hit destructions, sealing reliably, the mass transport valve of the valve gap band valve seat protecting jacket of long service life.
The present invention 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 present invention 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 present invention and the comparative trial of background technique prove that the present invention 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 invention.
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.
