Description

A new type of automatic descaling valve

technical field

The invention relates to a new type of automatic descaling valve, especially for a water-cooling unit and its connecting pipeline, which adopts a flexible flow stabilizer and realizes the comprehensive functions of automatic turbulent flow, automatic descaling and automatic drainage.

Background technique

Scaling of the water cooling unit and its connecting pipelines is the biggest problem that plagues the service life and cooling effect of the equipment. For example, the scale removal of the injection molding machine oil cooler requires dismantling the pipeline, which is messy and expensive. Existing descaling valves of many varieties are time-delay valves used for direct flushing, and some of them use a damping valve needle structure to reduce the blockage of the damping hole by scale and cause poor water supply. China Invention New Patent Announcement No. CN200410046786.7 discloses a flexible damping valve core composed of two semi-open dampers and springs, combined with steel needles and large and small sealing films, which solves the problem of the existing water valve structure. The high-precision processing requirements for the valve core assembly and the outer hexagonal valve body and the difficulty of not being able to achieve floating and flexibility. However, the outer hexagonal valve body of this structure is in the shape of a "turtle body" or "round cake" and has high requirements on the comprehensive quality of the diaphragm, button cover and water supply environment. The manufacturing difficulty and cost of the structural load are high, and the service life is also limited. restrictions, thereby increasing the user's cost of use.

Contents of the invention

The technical problem to be solved by the present invention is to design a new type of automatic descaling valve that can automatically descaling, has a simple structure, requires no maintenance, is convenient in material selection, low in cost, smart in installation and disassembly, labor-saving, and unlimited in use. The invention is applied to a device with a water-cooling unit, and is an automatic descaling valve capable of removing the scale attached to the inner cavity of the water-cooling unit and its pipeline, and at the same time preventing the regeneration of the scale. The invention adopts the flexible turbulence device with disturbed liquid flow to automatically generate disordered turbulent flow from laminar flow, so as to wash away the scale in the inner cavity of the water cooling unit and the pipeline to realize gradual removal. The invention also serves as a transition joint to connect the water-cooling unit and the pipeline, occupies almost no installation space, has low production cost, prevents clogging and requires no maintenance, has obvious automatic descaling effect, and is convenient and labor-saving for installation and disassembly. The problem that the existing water valve descaling device is complicated and expensive is solved. In particular, the flexible flow stabilizer is used to realize the comprehensive functions of automatic turbulent flow, automatic descaling and automatic drainage. It can be widely used in supporting parts of various water-cooling equipment, such as automatic descaling of injection molding machine oil coolers and water heating boilers.

Detailed ways

The present invention will be described in further detail below in conjunction with the accompanying drawings.

As shown in Figure 1, it is a schematic diagram of the automatic descaling valve described in the present invention. The present invention includes an outer hexagonal valve body (1), a flexible turbulator (2) installed in the outer hexagonal valve body (1) and a fixed The circlip (3) of the flexible turbulence device (2) is characterized in that the external hexagonal valve body (1) has an external thread and can be used as a transition joint.

In the present invention, under the premise of satisfying the requirements of the transitional connection between the cooling unit and the pipeline, the flexible turbulator (2) is installed inside the outer hexagonal valve body (1), and the flexible turbulator (2) uses a self- Lubricated plastic material, the flow section of the flexible turbulence (2) is processed into oblique holes, when the liquid flows through, the hydraulic force makes the flexible turbulence (2) automatically rotate, and the flexible turbulence (2) has a central round hole , when the liquid flow passes through, it acts as a flexible shaft, so that the flexible turbulator automatically rotates on this shaft. Thereby, the disordered turbulent flow is automatically generated from the laminar flow by the disturbed liquid flow, and the scale in the inner cavity of the water cooling unit and the pipeline is washed away to realize gradual removal.

The flexible turbulence device (2) is fixed by a clip spring (3), and the clip spring (3) has the function of preventing the flexible turbulence device (2) from falling off. The outer hexagonal valve body is used as a transitional connection part, and its water inlet and outlet are not restricted.

The advantage of the present invention is that the flexible turbulence device (2) is cleverly arranged inside the transition joint as the outer hexagonal valve body through reasonable design, without occupying space. Strive to achieve the purpose of effective automatic descaling, convenient installation, assembly time and low cost under the premise of meeting the requirements of working conditions.
