Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm valves, in particular to a multi-channel controlled diaphragm valve. Background Art

[0002] The diaphragm valve is a common type of shut-off valve. Its opening and closing parts are a combined diaphragm made of soft material, which separates the inner cavity of the valve body from the inner cavity of the valve cover and the driving components. Diaphragm valves are widely used in the chemical industry, food industry and biochemical industry.

[0003] Diaphragm valves often only have a single channel consisting of a water inlet and a water outlet, and generally do not have the function of multi-channel control. They cannot meet the user's operational requirements for channels of different numbers and positions, which leads to poor applicability of the device and difficulty in promotion. Based on this, we propose a new type of multi-channel control diaphragm valve. Utility Model Content

[0009] Preferably, a protective filter screen is threadedly connected to the top end of the water inlet pipe, so that the liquid medium introduced through the water inlet pipe can be filtered and purified, thereby achieving filtering and anti-blocking protection for the valve housing.

[0010] Preferably, the edge of the bottom of the protective filter is evenly and movably connected with a buffering rotating fan blade assembly arranged at equal angles.

[0011] Preferably, four buffer rotating fan blade assemblies are provided, and a connecting bearing is installed between the buffer rotating fan blade assembly and the protective filter screen.

[0012] Preferably, the valve housing is made of cast iron, and the inner wall of the valve housing is provided with a nano-ceramic anti-stick coating, so as to improve the structural strength and anti-stick and wear-resistant effects of the valve housing.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The multi-channel control diaphragm valve optimizes its own structure by providing a second water outlet channel, etc. The user can selectively adjust the operating handle on the on-off control valve core arranged corresponding to the first water outlet channel, the second water outlet channel, the third water outlet channel and the fourth water outlet channel on the valve housing according to the needs, so as to realize the on-off control of the four fluid medium channel structures composed of the water inlet pipe and the corresponding first water outlet channel, the second water outlet channel, the third water outlet channel and the fourth water outlet channel, so that the device realizes the advantages of multi-channel control, is easy to meet the use requirements of different numbers of channels and channels at different positions, has strong applicability and is easy to promote;

The user can sequentially insert the four on-off control valve cores into the first reserved control port, the second reserved control port, the third reserved control port and the fourth reserved control port that match the first water outlet channel, the second water outlet channel, the third water outlet channel and the fourth water outlet channel, and then use screws to fix the sealing substrate on the on-off control valve core and the corresponding assembly screw holes on the first reserved control port, the second reserved control port, the third reserved control port and the fourth reserved control port to fix the device. This enables the device to achieve the advantages of split assembly and facilitate inspection and maintenance;

[0016] (3) The multi-channel control diaphragm valve is installed with a protective filter screen, etc., so that when the device is operated, when the flow rate of the fluid medium introduced through the water inlet pipe is large, the fluid medium passes through the filter holes on the protective filter screen, utilizes the friction between the fluid medium and the protective filter screen, and consumes part of the impact energy of the fluid medium. In addition, the introduced fluid medium pushes the buffer rotating fan blade assembly arranged at equal angles and evenly connected at the bottom edge of the protective filter screen to rotate along the connecting bearing, thereby further consuming the impact energy of the fluid medium. This enables the device to achieve better buffer protection treatment and avoid the problem of excessive water flow causing damage to the inner wall of the valve housing due to excessive impact force.
