Abstract
The utility model discloses a quick-change valve with online-detachable valve plate and valve seat, which is used for solving the problems that vulnerable parts are difficult to replace and the maintenance cost is high. A valve cover (1) is fixedly connected with a valve body (9) by a bolt; the inner circle wall and upper plane of the valve cover (1) are respectively connected with the vertical plane and horizontal plane of an upper flange (5) with an L-shaped section; a first screw (14) fixedly connects the upper flange with the valve cover; the upper flange and the valve cover are sealed by a sealing ring (13); a ceramic valve seat (10) with an L-shaped section is positioned in an annular groove in the lower horizontal plane of the upper flange; a pressure ring (11) is matched with an annular step of the ceramic valve seat (10); a second screw (12) fixedly connects the pressure ring with the upper flange (5); a valve plate (7) is movably connected with a rotary arm (8); the rotary shaft (15) is fixedly connected with the rotary arm (8); the inner circle diameter of the valve cover (1) is greater than the outer diameter of the valve plate (7).
Description
technical field:
The utility model 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 is that an integral body is connected with valve body, valve seat is fixed on valve gap.The valve seat of valve and valve plate are easily damaged partss, after the damage of use a period of time, need to be changed.Valve gap is an integral body, while 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 are changed, whole deck valve door has assembled, and also needs to carry out bulk strength and leakage test, adjusts the cylinder piston throw of lever, can make valve plate standard-sized sheet and complete shut-down put in place.Everything just can be reinstalled original conveyance conduit after repairing and finishing.This process at least needs two day time, takes a lot of work, time-consuming, affects medium transport, has increased maintenance, the repair cost of enterprise.
the model utility content:
The purpose of this utility model be 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 utility model is achieved like this:
The Quick change valve that valve plate, valve seat can be dismantled online, the length of medium transport pipe 6 is 20-50cm, its flange and upper flange 5 are connected by double-screw bolt 4 and nut 3, the screw of the screw of double-screw bolt 4 and the first screw 14 layout that misplaces on upper flange 5.
Seal arrangement between upper flange and valve gap is the seal ring 13 in upper flange or valve gap groove.
Upper flange is the mutually friction tight concave-convex annular structure of upper flange and valve gap with the seal arrangement between valve gap.
The utility model 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 while changing valve seat and get final product, and do not need whole valve gap is pulled down.
(2) when 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 be overhauled online, do not need whole valve taken off from pipeline.
(4) while changing valve seat, valve plate, 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.
(5) easy to maintenance, convenient, take a short time, can greatly save maintenance cost.
the accompanying drawing explanation:
Fig. 1 is structural drawing of the present utility model.
embodiment:
As valve seat or valve plate damage, while 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 coordinated with upper flange 2 on valve gap 1 is greater than the external diameter of valve plate 7, and upper flange 5 can take out valve plate 7 and be changed after removing.
