Description

Mother-in-law flow control regulator check valve

This creation provides the technical field of a flow control and pressure stabilizing check valve, especially a mother-child type flow control and stabilizing check valve technically, in which a check assembly and a flow control switch in the valve body shell circulate through the same The central axis is installed in sequence, so that small flow can still be sensed, and the overall occupied space can be greatly reduced, which not only effectively reduces the weight and parts, but also effectively improves and reduces the maintenance cost in processing, manufacturing and assembly By.

According to the early pipeline configuration of electronic fluidic pressurizers, the check valve is an absolutely necessary equipment component, and its pressure flow control equipment is also a necessary equipment component. Therefore, conventional electronic fluidic pressurization There are many necessary components for the machine, and the cost will inevitably increase if there are too many components. The repair and maintenance of multiple components will take more time, and the space occupied by more components will naturally be larger. On the other hand, the conventional sensing equipment can only have a sensing signal when the flow rate is large, and there is no sensing signal when the flow rate is small, which is very easy to cause unstable water supply and frequent opening and closing of the electronic flow control pressurizer motor in a short period of time. Frequent opening and closing of the pressurizer motor controlled by the electronic fluid will cause damage or burnout.

Refer to Figures 1 and 3. Due to the lack of the above-mentioned conventional knowledge, the author of this case developed the application No. 109215440 "Mother-in-Child Fluid Control Stabilized Check Valve", and applied for a new type of patent, hereinafter referred to as The known prior application includes: the integrated valve housing a10 uses a central partition to separate the water inlet and outlet spaces, and the central partition is provided with large and small openings for a backstop component a30 and a flow rate respectively. The control switch a40 is installed, and the check assembly a30 includes a valve plug rod as a first elastic member against which the set pressure is sealed to the large opening; the flow control switch a40 is assembled to the valve body, and a flow sensing element Set in the flow switch fixing seat, the flow control rod is pressed by the second elastic part and sealed to the small opening; accordingly, even if the water flow is small, it can still be sensed by the flow sensing element, so that the electronic flow control pressurizer can maintain Run the signal and provide a stable water supply.

However, although the prior application of its conventional application can achieve that even a small flow of water can still be sensed by the flow sensing element, so that the electronic fluidic control pressurizer can maintain the operation signal and provide stable water supply, but the backstop component a30 and related parts The components occupy a space around the first central axis a1 and move up and down, and the flow control switch a40 and related components occupy a space around the second central axis a2 and move up and down. Compared with the creation of this case, which only needs a space around the central axis and up and down activities, the creation of this case saves more than half of the space compared with the previous application, and because of the space saving, the shell and all components are also changed in design, and its shell The overall structure is simpler, the components are fewer and simpler, the production and assembly are naturally easier and faster, and the cost is also reduced By.

Therefore, in view of the problems existing in the above-mentioned conventional structures, how to develop a more ideal and practical innovative structure is what consumers are eagerly looking forward to, and it is also the goal and direction that related businesses must work hard to develop breakthroughs.

In view of this, the author has been engaged in the manufacturing, development and design of related products for many years. After careful design and careful evaluation for the above-mentioned goals, he finally obtained a truly practical creation.

In order to achieve the above-mentioned purpose, this creation provides a mother-in-law flow control stabilized pressure check valve, which includes: a valve housing, which is sequentially installed with a check assembly and a flow rate along a central axis. The control switch, the backstop assembly includes a valve plug disc that is pushed against by an outer ring elastic member to set the pressure to seal to a large opening, the flow control switch includes a flow control seat for pressure control, and a flow control rod as an inner ring elastic member Push against and seal to a small opening opened through the valve plug plate, and a flow sensing element is installed at the flow control seat to sense the flow rate. Accordingly, even small flow water can still be sensed by the flow sensing element. Make The electronic flow control pressurizer can maintain the running signal and provide stable water supply, and all components are installed on the inner and outer layers or the upper and lower layers on a central axis, which greatly reduces the occupied space, not only effectively reduces weight and zero The reduction of components can effectively improve and reduce the maintenance cost in processing, production and assembly.
