Abstract

The utility model relates to a ring cover valve 2 for controlling liquid to flow out of a valve body (1) which is a cylinder body with one closed end and a liquid outlet (2) at the side wall. The outer part of the valve body is sheathed with a cylinder valve (3) whose cylinder wall is provided with the liquid outlet (4) and whose outer wall is provided with a control stem (5). The outer walls of the valve body (1) at both ends of the valve (3) are respectively provided with a ring-retaining groove (6) and a retaining ring, wherein, the outer sides of the ring-retaining grooves at the outer walls of the valve body (1) are provided with a protruding body (10) whose front and back positions at the ends of the valve (3) are respectively provided with the protruding bodies (8), (9).

Description

Ring cover valve

This Ring cover valve is a kind of switch that controlling liquid flows out that is used for.

The valve of daily use for a long time is by housing, spool, sealing gasket, valve rod ... Deng composition, its structure is numerous and diverse, and the sealing gasket breakage easily takes place, and faults such as valve stem crack are repaired inconvenience.

The purpose of this utility model provides a kind of valve, and it is not only simple in structure, and the reliability height is easy to maintenance, and makes easily.

The valve body of this Ring cover valve (1) (referring to accompanying drawing 1 and accompanying drawing 2) is the garden cylindrical shell of end sealing, and the screw thread that the other end is provided with connecting pipe is a liquid-inlet.On the barrel of valve body (1), have several liquid outlet openings (2), the periphery of valve body (1) is with the ring set valve (3) of a garden tubular, have several liquid outlet openings (4) on the barrel of valve (3), the outer wall of valve (3) is provided with (or a pair of) control handle (5), being in valve (3) end positions on valve body (1) outer wall respectively has a circlip groove (6) and back-up ring (7) to make the valve (3) can not be axially displaced, control handle (5) can make valve (3) rotate around valve body (1), rotate to both liquid outlet opening (2) and (4) on time, the liquid in the pipeline just through valve body (1) inner chamber from liquid outlet opening (2) and (4) outflow.When manipulation control handle (5) made liquid outlet opening (2) with (4) dislocation, liquid outlet opening (2) was blocked by the barrel of valve (3), and liquid just stops to flow out.

There is an excrescence (10) in the outer wall circlip groove of valve body (1) outside, respectively is provided with excrescence (8) in valve (3) end of (10) front and back position and (9) are limited between (8) and (9) rotary distance of valve (3).The closed end of valve body (1) has a hexagon (or quadrilateral) excrescence, and spanner reverses and puts forth effort when supplying by dress.

Liquid outlet opening (2) on this Ring cover valve valve body (1) both can be arranged in delegation vertically also can be arranged in number row (referring to accompanying drawing 3) vertically.The liquid outlet opening (2) corresponding identical (referring to accompanying drawing 4) that the quantity of the liquid outlet opening (4) on the valve (3) and arrangement position and valve body (1) end.Liquid outlet opening (2) and (4) can be that shape hole, garden also can be made into rectangular opening (or hole of other shape).

The control handle of this Ring cover valve (5) with then can control container after buoyancy aid connects automatically in liquid level height (referring to accompanying drawing 5).When liquid level is increased to setting height, buoyancy aid (11) come-up drives control handle (5) and moves upward, thereby valve (3) is rotated up around valve body (1), the liquid outlet opening (4) of valve (3) leaves the liquid outlet opening (2) on the valve body (1), liquid outlet opening (2) is blocked by the barrel of valve (3), liquid stops to flow in the container, and liquid level tops out.Also by the retaining of the excrescence (10) on the valve body (1) jail, valve (3) can not continue to rotate up excrescence (8) on valve this moment (3) because of a variety of causes.When liquid level height in the container descends, buoyancy aid (11) descends thereupon, driving control handle (5) moves downward, valve (3) is also along with being rotated down, valve (3) rotates to liquid outlet opening (4) and liquid outlet opening (2) on time, liquid by pipeline through valve body (1) inner chamber from liquid outlet opening (2) and (4) inflow container.Excrescence (9) on valve this moment (3) is blocked by the excrescence (10) on the valve body (1), and valve (3) can not continue to be rotated down because of a variety of causes.Buoyancy aid (11) can be the hollow body of spheroid, garden tubular or cuboid.

When closing liquid outlet, directly do not bear this Ring cover valve the fluid pressure in the pipeline, so the required power of closing is little, need not adopt spiral to compress closes, buoyancy aid than the floating ball lever formula of using at present when especially being applied to control automatically liquid level height in the container can dwindle, and avoided the lever distortion, faults such as dislocation are closed in the pin wearing and tearing.
