Abstract

The utility model relates to a quick on-off sebific duct valve and pertains to the technical field of water treatment machinery. The sebific duck valve comprises an upper valve body, a lower valve body, a rubber duct and a fastening bolt and nut. The upper and lower valve bodies are fastened into a valve body casing by the fastening bolt and nut. Two ends of the sebific duct are provided with a twin-flange. The sebific duct is tightly pressed between the upper valve body and the lower valve body. The quick on-off sebific duct valve designed by the utility model has the advantages of simple structure, combined material of the valve by adopting the engineering plastic or press-casting of the valve body and a sebific duct core, basically no mechanical processing allowance, ignored head loss occurred in the opening of the valve, corrosion-resistance, almost suiting for most working medium, no leakage, no maintenance and reliable working, and is in particular suitable for automatic control of water treatment and filtering system and also can be used for other industrial pipelines.

Description

Rapidly opened and closed rubber pipe valve

Technical field

The utility model relates to a kind of rapidly opened and closed rubber pipe valve, utilizes the distortion of rubber pipe to open and close operation, belongs to the water processor machinery technical field.

Background technique

Now, the various gate valves that use in the various pipe-line systems, ball valve, butterfly valve, stop valve etc., all might there be problems such as poorly sealed, leakage in its structure and make all complicatedly.Though states such as Germany, Finland also have various forms of rubber pipe valves to sell, structure is still complicated, and its price is too high, and as the manually operated valve of identical bore, price differs about ten times unexpectedly, thereby has more problem in the production and sales of market at home.

The model utility content

The purpose of this utility model is the deficiency at existing various gate valves, design a kind of rapidly opened and closed rubber pipe valve, its structure is made improvements, the rubber pipe that employing is clipped between the upper and lower valve body directly opens and closes element, make that its structure is greatly simple, manufacturing is easy to assembly, cost is low, be used for substituting various conventional gate valves, also can in other industrial pipeline, make cut-off valve simultaneously and use in the robot control system(RCS) of feedwater and effluent treatment and filtering.

The rapidly opened and closed rubber pipe valve of the utility model design comprises upper valve body, following valve body, rubber pipe and clamping bolt nut.Described upper and lower valve body is tightened to valve shell by the clamping bolt nut; The two ends of described rubber pipe have two flanges, and rubber pipe is pressed between the upper and lower valve body.

The rapidly opened and closed rubber pipe valve of the utility model design, in use, pressurized air or press water enter from upper valve body top water intake, rely on the pressure of fluid to make the rubber pipe distortion and then make valve airtight.Generally speaking, pressurized air or press water are to provide by air bells compressor or water pump, and the turnover of pressure gas or water is then finished by solenoid valve.

The rapidly opened and closed rubber pipe valve of the utility model design has the following advantages:

1, simple in structure, the material of valve adopts engineering plastics or casting to press valve body and rubber tube core to combine essentially no machining amount;

2, loss of head can be ignored when valve opening;

3, corrosion-resistant, almost can be applicable to most of working mediums;

4, do not have leakage, need not maintenance, reliable operation;

5, the batch process cost is lower, has the power of striving unexpectedly;

6, be specially adapted to automatic control in the water processing filtering system, also can be used for other industrial pipeline.

Description of drawings

The structural representation of the rubber pipe valve that Fig. 1 designs for the utility model

Among Fig. 1, the 1st, upper valve body, the 2nd, following valve body, the 3rd, the rubber pipe that fuses with two flanges, the 4th, advance/give vent to anger/water hole, the 5th, clamping bolt nut, the 6th, gas/water chamber.

Embodiment

As shown in Figure 1, the rapidly opened and closed rubber pipe valve of the utility model design comprises upper valve body 1, following valve body 2, rubber pipe 3.Upper valve body 1 is tightened to valve shell with following valve body 2 by binder bolt nut 5, and the rubber pipe 3 of the two flanges of band then by upper valve body 1 and following valve body 2 compactings therebetween.Advance/give vent to anger/water hole 4 is positioned at the top of upper valve body 1.Upper and lower valve body 1 and 2 inner space, promptly the upper and lower of gas/water chamber 6 is interconnected.

Structure with Fig. 1 is an example, working procedure of the present utility model be achieved in that by the advancing/give vent to anger of rubber pipe valve upper valve body 1 top/water hole 4 up and down communicating space one gas/water chamber 6 of valve body feed pressurized air or press waters, make sebific duct 3 produce distortion until closed circuit.Conversely, when gas/water chamber 6 pressurized air or press water pressure release, then rubber pipe 3 since the elasticity of self restore to the original state automatically, thereby working medium is wherein flowed smoothly.According to the arrangement of automatic program, gas/water chamber 6 can be inflated/water and pressure release repeatedly, rubber pipe valve is opened and closed go round and begin again, and circulation endlessly.

Pressurized air or press water are provided by air compressor or water pump, realize the inflation/water and the pressure release of gas/water chamber 6 in the rubber pipe valve according to the proceedings that opens and closes, thereby realize the normal keying of rubber pipe valve.

The material of rubber pipe 3 can adopt natural rubber or other industrial rubber according to the requirement of working medium.Rubber pipe opens and closes number of times repeatedly and can reach more than ten thousand times under the normal condition.

Because the two ends of rubber pipe 3 are flanged dishes, so any valve, the Guan Douke that link with the utility model rubber pipe valve directly link, and need not add sealing gasket in addition, this moment, any leakage part of working medium was impossible.Rubber pipe valve will have very long operating life, and unique maintenance load is just opened valve body replacing rubber pipe up and down.

The rubber pipe valve of the utility model design, the filtration treatment that is specially adapted to feed water is applicable to that too other industrial pipeline work opens and closes valve.

Claims

1, a kind of rapidly opened and closed rubber pipe valve is characterized in that this rubber pipe valve comprises upper valve body, following valve body, rubber pipe and clamping bolt; Described upper and lower valve body is tightened to valve shell by the clamping bolt nut; The two ends of described rubber pipe have two flanges, and rubber pipe is pressed between the upper and lower valve body.
