Abstract

The utility model relates to a gate valve device used for controlling and adjusting the water distributing quantity in a water treating distribution reservoir, which comprises a start and stop mechanism, a support frame, a pressure ring, and a sealing ring. The utility model is characterized in that the start and stop mechanism of which the threaded rod end is rigidly connected with a movable sleeve barrel is installed on the support frame, the movable sleeve barrel is sheathed in a fixed sleeve barrel and can move upwards and downwards, and the movable sleeve barrel through a sliding block slides on a guide bar welded on the support frame to reduce the axial wobble of the movable sleeve barrel. The upper and the lower ends of the fixed sleeve barrel are respectively connected with the guide bar and the flange of a water yielding steel tube on the reservoir bottom, and a sealing ring is imbedded under the pressure ring on the guide bar on the inner wall at the upper end of the fixed sleeve barrel. The utility model can give out the water distributing quantity exactly and has the advantages of convenient operation and easy maintenance.

Description

Gate valve device in distribution reservoir

The utility model relates to the gate-valve device of in a kind of water treatment distribution reservoir (well) water yield dispensing being regulated control, contains opening/closing mechanism, supporting frame, pressure ring, seal ring.

At present, in purification of water quality was handled, the adjusting of the dispensing water yield was mainly undertaken by dull and stereotyped cast iron gate or valve, and flowmeter is set; Generally, flowmeter need be installed in flow and locate more gently, promptly needs the water delivery straight length of certain-length, like this, has increased area is set, limit because of condition sometimes flowmeter can't be set, thereby can't metered flow; When discharging water because of the use gate in addition, the gate single face is stressed, easily loss inconvenience maintenance.

The purpose of this utility model be provide for fear of above-mentioned the deficiencies in the prior art part a kind of simple in structure, stable, use the novel gate-valve device in reliable, as can directly to measure accurately water distribution quantity, intensity height, the easy-maintaining distribution reservoir (well).

The purpose of this utility model can realize by following measure:

Gate-valve device in a kind of distribution reservoir contains opening/closing mechanism, supporting frame, pressure ring and seal ring; It is characterized in that opening/closing mechanism being installed at the center, upper end of supporting frame, cross center rigid joint in the screw rod end of opening/closing mechanism and the quill, end periphery symmetrical position place is welded with slide block respectively on quill, and slide block can slide on the guide rod that connects the supporting frame two ends with bolt; Quill is enclosed within the fixed muffle, and can upper and lower therein slip; The upper end of fixed muffle and guide rod lower end and pressure ring connect firmly, and the other end links to each other with the pre-buried flange of water outlet steel pipe at the bottom of the pond.

The purpose of this utility model also can realize by following measure:

Cross is to be welded by I-steel, channel-section steel in the quill of the gate-valve device in the distribution reservoir, and is welded with angle ring in the top periphery of quill, is welded with steel loop at the fixed muffle outer wall; Its pressure ring is to be welded with breach flange and steel pipe, in the breach of the breach flange of guide rod insertion pressure ring; The fixed muffle upper inside wall studs with two seal rings in the steel pipe lower end of pressure ring, and is welded with the support annulus under it.

The utility model has following advantage compared to existing technology:

1, the utility model can be according to the requirement of water distribution quantity, regulates more accurate water distribution quantity in predetermined range arbitrarily, and also can make water distribution quantity is zero, when being about to quill and rising to the extreme higher position (being higher than water level) can stop water distribution.

2, quill of the present utility model and fixed muffle be with steel loop and section steel reinforcement, thus intensity height, good rigidly, stable, use reliable.

3, the utility model adaptability is strong, and adjusting water distribution quantity scope is wide, not only has the convenience of lock but also have the flexible of valve.

4, of the present utility model simple in structure, easy to process, cost is low, easily damaged parts weight is changed easily.

Concrete structure of the present utility model is provided by the following drawings:

Fig. 1 is a structural representation of the present utility model.

1-opening/closing mechanism 2-supporting frame 3-guide rod

4-slide block 5-quill 6-pressure ring

7-seal ring 8-fixed muffle

The utility model is also incited somebody to action in conjunction with the accompanying drawings, and 1 embodiment is described in further detail:

With reference to Fig. 1, opening/closing mechanism (1) can be selected worm-type open-close machine for use, with its screw rod end welded flange; Selecting for use wide then is that 950 millimeters sheet metal rolls that to form internal diameter be 1288 millimeters quill (5), and solder joint, be welded with cross and the angle ring that I-steel is made respectively in cylinder upper inside wall and outer wall again, and connect firmly at the flange of cross center welded flange and opening/closing mechanism screw rod end, the end periphery symmetrical position is welded with long 220 millimeters, wide 60 millimeters, thick 16 millimeters sheet material and makes slide block (4) (4 ') on cylinder then; Selecting wide 626 millimeters sheet metal to roll to form internal diameter for use is 1388 millimeters fixed muffle (8), and the reinforcing steel loop of solder joint and periphery; Wall thickness of cylinder is 16 millimeters, and selecting length then for use is that 1320 millimeters two channel-section steels are made guide rod (3) (3 '), and the slide block (4) of quill (5) can slide thereon, in the breach of the breach flange of the lower end insertion pressure ring (6) of guide rod (3); Pressure ring (6) (6 ') is to be made by breach flange welded steel pipe; The supporting frame (2) that the upper end of guide rod (3) (3 ') and channel-section steel are made links, and the other end links to each other with the upper end of fixed muffle (8), and the other end of fixed muffle (8) links to each other with the pre-buried flange of water outlet steel pipe at the bottom of the pond; Stud with two seal rings (7) in the steel pipe lower end of pressure ring (6) fixed muffle (8) upper inside wall, and under it, be welded with the support annulus.

Using method: when need distribute the water yield for from distribution reservoir each distributed water pipe, need only be according to the scale of the antenna pull-rod type graded tube of opening/closing mechanism (1), the pivoted arm that rotates opening/closing mechanism (1) rises quill (5) or decline, can distribute more accurate water distribution quantity; This gate-valve device can be made gate at quill (5) and use when being higher than water level.
