Abstract

The invention discloses a quick-replaced valve with an online detachable valve plate and valve seat, which aims to solve the problems of difficulty in replacing easily-damaged parts and high in maintenance cost. A valve cover (1) is fixedly connected with a valve body (9) by using a bolt; the inner circular wall and the upside of the valve cover (1) are respectively connected with a vertical surface and a horizontal surface of an upper flange (5) with an L-shaped section; the upper flange is fixedly connected to the valve cover through a first screw (14); the upper flange and the valve cover are sealed by using a sealing ring (13); a ceramic valve seat (10) with an L-shaped section is located in an annular groove in the lower horizontal surface of the upper flange; a pressing ring (11) is matched with an annular step of the ceramic valve seat (10) and fixedly connected to the upper flange (5) through a second screw (12); a valve plate (7) is movably connected with a rotary arm (8); a rotating shaft (15) is fixedly connected with the rotary arm (8); the diameter of an inner circle of the valve cover (1) is larger than the external diameter of the valve plate (7).

Description

The Quick change valve that valve plate, valve seat can be dismantled online
Technical field:
The present invention is relevant, especially relevant with Quick change valve with the valve of carrying powder, slurries, granule medium.
Background technique:
The valve of existing conveying powder, slurries, granule medium, valve gap are that an integral body links to each other with valve body, and valve seat is fixed on the valve gap.The valve seat of valve and valve plate are easily damaged partss, need change after the damage of use a period of time.Valve gap is an integral body, when changing valve seat and valve plate, at first whole valve will be pulled down from conveyance conduit, and then pull down the component such as integral valve cover, valve seat, valve plate, valve rod, the dismounting position is many, and the take-down time is long, and the parts such as middle flange bolt and Sealing are also easily damaged in dismounting.After valve plate, valve seat were changed, whole deck valve door assembling was finished, and also need carry out bulk strength and leakage test, adjusts the cylinder piston throw of lever, and valve plate standard-sized sheet and complete shut-down are put in place.Everything just can be reinstalled original conveyance conduit after repairing and finishing.This process needs two day time at least, takes a lot of work, time-consuming, affects medium transport, has increased maintenance, the repair cost of enterprise.
Summary of the invention:
The purpose of this invention is to provide a kind of simple in structure, be convenient to change easily damaged parts, easy to operate, the Quick change valve that the valve plate that maintenance cost is low, valve seat can be dismantled online.
The present invention is achieved like this:
Valve gap 1 is connected with valve body 9 usefulness bolts, the inner round wall of valve gap 1 is that the vertical face of L shaped upper flange 5 is connected with horizontal plane with being connected respectively with the cross section, the first screw 14 is connected in upper flange on the valve gap, seal with seal ring 13 between upper flange and the valve gap, the cross section is that L shaped ceramic valve seat 10 is positioned at the circular groove on the lower horizontal plane of upper flange, trim ring 11 cooperates with the ring-shaped step of ceramic valve seat 10, the second screw 12 is connected in trim ring on the upper flange 5, the top flange with medium transport pipe 6 of upper flange is connected, valve plate 7 is flexibly connected with pivoted arm 8, rotating shaft 15 is connected with pivoted arm 8, and the interior circular diameter of valve gap 1 is greater than the external diameter of valve plate 7.
The Quick change valve that valve plate, valve seat can be dismantled online, the length of medium transport pipe 6 are 20-50cm, and its flange and upper flange 5 are connected by double-screw bolt 4 and nut 3, and the screw of the screw of double-screw bolt 4 and the first screw 14 is arranged in upper flange 5 dislocation.
Seal arrangement between upper flange and the valve gap is the seal ring 13 in upper flange or the valve gap groove.
Upper flange is the mutually friction tight concave-convex annular structure of upper flange and valve gap with seal arrangement between the valve gap.
The present invention has the following advantages:
(1) valve gap and upper flange removably connect, and ceramic valve seat is fixed on dismountable upper flange, only need pull down pipe nipple medium transport pipe and upper flange when changing valve seat and get final product, and do not need whole valve gap is pulled down.
When (two) valve plate is changed, only need pull down pipe nipple medium transport pipe and upper flange, just can take out replacing, not need whole valve gap is pulled down.
(3) valve seat, valve plate damage, and can overhaul online, do not need whole valve taken off from pipeline.
The driving components such as not mobile cylinder piston rod, clevis, rotating shaft after valve seat, valve plate have been changed, do not need to carry out intensity, sealing and the running test of complete machine when (four) changing valve seat, valve plate.
(5) easy to maintenance, convenient, take a short time, can greatly save maintenance cost.
Description of drawings:
Fig. 1 is structural drawing of the present invention.
Embodiment:
Valve gap 1 and the valve body 9 usefulness bolts formation housing that is connected.Valve gap 1 removably connects with upper flange 5, and upper flange 5 is connected on the valve gap 1 by screw 14, therebetween with seal ring 13 sealings.Ceramic valve seat 10 usefulness trim rings 11 are connected in the lower channel of upper flange 5 by screw 12.Valve plate 7 is flexibly connected with pivoted arm 8, and rotating shaft 15 is connected with pivoted arm 8, and rotating shaft 15 drives valve plate 7 by pivoted arm 8 and is rotated motion, realizes the opening and closing of valve plate and valve seat.The long medium transport pipe 6 of 30cm is connected by double-screw bolt 4 and nut 3 with upper flange 5.The screw of the screw of double-screw bolt 4 and screw 14 is arranged in upper flange 5 dislocation.
Damage such as valve seat or valve plate, when needing to change, at first take off medium transport pipe 6, then unload screw 14, take out upper flange 5, with regard to replaceable ceramic valve seat 10.The diameter in the hole that cooperates with upper flange 2 on the valve gap 1, can take out valve plate 7 and change after upper flange 5 is removed greater than the external diameter of valve plate 7.
