Abstract
The invention discloses a sleeve valve with an adjustable longitudinal flow, which comprises a valve bush, wherein a piston cylinder is arranged in the valve bush, sliding matching is formed between the piston cylinder and the valve bush, and guide holes are arranged on the piston cylinder. The sleeve valve is arranged between an upper pool and a lower pool, in particular, a hole is drilled on a platform between the upper pool and the lower pool, the valve bush is fixed on the hole in a manner of an expansion bolt or embedded steel plate, the upper end face of the valve bush is embedded with a flat rubber ring to be used as an end face seal, and the piston cylinder is arranged on the valve bush, therefore, because the valve body is structurally characterized by being closed and opened by a sleeve vertical motion, when the piston cylinder moves upwards, the guide holes of the piston cylinder play a role of guiding, with the increase of the lifting amount, the total guide area is continuously increased until the piston cylinder passes through the complete stroke, and the valve is equally completely opened. When the piston cylinder moves downwards, the quantity of the guide holes on the side surface is continuously reduced until the flat rubber end face is in complete contact with a fixed cylinder to play a role of sealing, and the valve is completely closed.
Description
Technical field
The present invention relates to a kind of valve, what be specifically related to is a kind of adjustable telescoping valve of vertical flow that is used for water conservancy and engineering of water treatment.
Background technology
Existing water level and water yield conditioning equipment mainly contain cast iron edge copper gate, channel gate, stoplog lock, rotation weir gate and various planes valve (as butterfly valve etc.), it is realized the straight line of various gate valves by manual opening-closing machine or electronic headstock gear and rotatablely moves, to reach the purpose of regulating water level.The use limitation and the shortcoming of such gate valve are:
1, owing to be subjected to the constraint of himself structure, Water Level Control before and after can only being used for comparatively formats the requirement of mounting condition;
2, leakage is big, generally at 1.25L/mmin;
3, be not easy to Water Level Control up and down.Particularly in current resource scarcity, under the situation of an inch of land is an inch of gold, some hydraulic engineerings are built the pond body of stacked structure in order to save the soil.At this moment, use a kind of new equipment satisfy water level between the pond and water yield adjusting up and down with regard to needing, and existing valve only is applicable to that direction of flow is the occasion use of horizontal direction, can not satisfy the requirement of longitudinal stream direction of flow.
Summary of the invention
Purpose of the present invention is exactly to solve the operating mode that above-mentioned gate valve does not satisfy, and provides a kind of and can be suitable for the adjustable telescoping valve of vertical flow of direction of flow occasion up and down.
The present invention adopts following technical scheme:
The adjustable telescoping valve of a kind of vertical flow comprises: valve pocket be provided with piston cylinder in valve pocket, and formation is slidingly matched between piston cylinder and the valve pocket, is provided with pod apertures on piston cylinder.
Compared with prior art, the present invention has following advantage:
The present invention can be installed between the sink, specifically, perforate on the platform between two ponds up and down, the form of valve pocket by expansion bolt or pre-embedded steel slab is fixed on the hole, the valve pocket upper surface is inlayed flat rubber ring and is done end face seal, piston cylinder is installed on valve pocket, like this because valve body structure is the telescopic open and close valve that moves both vertically, when piston cylinder moves upward, the piston cylinder pod apertures plays guide functions, and along with the increase of lifting capacity, total water conservancy diversion area constantly increases, until covering whole strokes, the valve equivalence is all opened.When piston cylinder moved downward, side pod apertures quantity constantly reduced, and contacted fully with stationary cylinder until flat rubber end face, sealed, and valve is closed fully.The size of pod apertures and quantity can be determined according to technological requirement, to satisfy the needs of regulating the speed of the different turnover water yields.
Pod apertures on the piston cylinder makes the present invention can realize the trace adjusting of fluid.Because fluid enters from an end of the present invention,, flow out from the other end of the present invention again through the pod apertures on the piston cylinder, therefore, when piston cylinder was raised or put down, corresponding variation will take place in the pod apertures working quantity, thereby changed the flow of the present invention of flowing through, the final trace of realizing is regulated.

Fig. 1 is a cast iron edge copper gate scheme of installation.
Fig. 2 is the channel gate scheme of installation.
Fig. 3 is a structural representation of the present invention.
Fig. 4 be the embodiment of the invention open the valve schematic diagram.
Fig. 5 is the pass valve schematic diagram of the embodiment of the invention.
The specific embodiment
The adjustable telescoping valve of a kind of vertical flow comprises: valve pocket 1, in valve pocket 1, be provided with piston cylinder 2, and, form between piston cylinder 2 and the valve pocket 1 and be slidingly matched, on piston cylinder 2, be provided with pod apertures 21.In the present embodiment, consider the needs of flow-control and total flow (being maximum stream flow), the area sum of all pod apertures 21 equals the inside space of valve pocket 1 on the piston cylinder 2.
During concrete the use, the present invention is installed on the platform between two ponds up and down of stacked structure, piston cylinder 2 is connected on the lifting appliance 3, lifting appliance 3 is used to drive piston cylinder 2 and moves up and down, described lifting appliance 3 comprises frame 32, is provided with headstock gear 31 in frame 32, at headstock gear 31 drive lead screw 33 that has been threaded, headstock gear 31 can be bought from the market, and 33 of drive lead screws can be connected on the headstock gear 31 according to the explanation of headstock gear 31.The lifting of the piston cylinder 2 in the telescoping valve and close and can regulate by screw mandrel, configurable as required manual or electronic and manual and electric double-purpose headstock gear, simple to operate, easy for installation.When using the manual opening-closing machine, excessive in order to prevent to regulate, can on screw mandrel, install stopping means additional.Guarantee safe handling.
