Water regulating valve

This creation is related to water heaters; in particular, a water regulating valve installed in a water heater.

Press, the water volume regulating valve is installed on a water pipe of the water heater for regulating the water flow into the water heater. A conventional water volume regulating valve 1 as shown in FIG. 1 includes a pipe body 10 and a water amount adjusting assembly 12. The pipe body 10 has a water inlet 102, a water outlet 104 and a valve port 106 between the water inlet 102 and the water outlet 104. The water volume adjusting assembly 12 includes a motor 122, a shaft 124, a valve plug 126 and a fixing base 128. The motor 122 is disposed on the tube body 10. The shaft 124 is connected to the motor 122 at one end and the valve plug 126 is connected to the other end. The fixing seat is located between the motor 122 and the valve plug 126. The fixing base 128 has a screw. The hole 128a is passed through a threaded section 124a of the shaft 124. The control of the motor 122 can drive the valve plug 126 to move relative to the valve port 106, thereby changing the degree of opening between the valve plug 126 and the valve port 106. Adjust the flow of water through.

Since there is a machining tolerance between the screw hole 128a of the fixing seat 128 and the thread segment 124a of the shaft 124, there will be a backlash therebetween, and when the water flows, the water flow directly impacts the side of the valve plug 126. The aforementioned backlash will cause the shaft 124 to lie relative to the fixed seat 128 to cause the shaft 124 to vibrate. In particular, the smaller the degree of opening between the valve plug 126 and the valve port 106, the greater the force of the water flow impinging on the valve plug 126, so that the vibration degree of the shaft 124 is increased, and the entire water heater is easily formed. Total Vibration, severely caused the water heater to malfunction due to excessive vibration.

In view of this, the purpose of this creation is to provide a water volume regulating valve that can effectively avoid vibration.

In order to achieve the above objective, the water regulating valve provided by the present invention comprises a water regulating valve which is installed on a water pipe of a water heater and includes a pipe body, a motor, a shaft and a valve plug. Wherein, the pipe body has a water inlet, a water outlet and a valve port between the water inlet and the water outlet; the motor is disposed on the pipe body; the shaft is located in the pipe body, and one end of the shaft Connecting the motor; the valve plug is disposed on the shaft and located between the valve port and the water outlet, the valve plug has a front side and a rear side, the front side faces the valve port, and the rear side faces the motor The motor drives the shaft to reciprocate relative to the valve port to adjust the degree of opening between the valve plug and the valve port.

Thereby, the water volume regulating valve can be used to reduce vibration and avoid resonance of the water heater.

In order to explain the present invention more clearly, the preferred embodiment will be described in detail with reference to the drawings. 2 to 4 show a water volume regulating valve 2 according to a preferred embodiment of the present invention, which is installed on a water supply pipe of a water heater. The water volume regulating valve 2 includes a pipe body 20, a water amount adjusting component 28, a water flow detecting component 38 and a water temperature detector 40.

The pipe body 20 of the present embodiment is composed of a connecting water inlet pipe section 22, a connecting pipe section 24 and an outlet water pipe section 26, wherein the water inlet pipe section 22 has a water inlet 222 for water supply and injection. The section 22 is perpendicular to the connecting pipe section 24; the junction of the water inlet pipe section 22 and the connecting pipe section 24 has a valve port 242 having a side port 244 communicating with the outlet pipe section 26, the outlet pipe section 26 having A water outlet 262 is supplied with water. A support column 224 is formed on the wall of the water inlet pipe section 22. The support column 224 has a shaft hole 224a facing the connecting pipe section 24. The pipe wall of the water inlet pipe section 22 has a uniform hole 226 extending through the pipe wall.

The water quantity adjusting component 28 includes a motor 30, a shaft 32, a valve plug 34 and a fixing base 36. The motor 30 is disposed at one end of the connecting pipe section 24 opposite to the valve port 242; the shaft 32 is located at the connection In the pipe section 24, one end of the shaft 32 is connected to the motor 30. The shaft 32 has a threaded section 322 and a small diameter section 324 which projects into the shaft hole 224a of the support column 224. The valve plug 34 is located between the water outlet 262 and the valve port 242. The valve plug 34 has a front side 342, a rear side 344 and a through hole 346. The front side 342 faces the valve port 242, and the rear side 344 faces the valve port 242. The motor 30 has the through hole 346 extending through the front side 342 and the rear side 344. The shaft 32 passes through the perforation 346 to engage the valve plug 34. The fixing seat 36 is disposed in the connecting pipe section 24 between the motor 30 and the valve plug 34. The fixing seat 36 has a screw hole 362 through which the threaded portion 322 of the shaft 32 passes. The motor 30 can drive the shaft 32 to reciprocate relative to the valve port 242 to adjust the degree of opening between the valve plug 34 and the valve port 242 to regulate the flow of water through the valve port 242. The support column 224 can effectively support the shaft 32, so that the shaft 32 can move smoothly.

With the above structure, when water flows through the water inlet 222, At the valve port 242, since the front side 342 of the valve plug 34 faces the valve port 242, the pressure formed by the water flow will press against the front side 342, causing the valve plug 34 to push the shaft 32 backward. In this way, the threaded section 322 of the shaft 32 can be effectively abutted against the screw hole 362 of the fixing seat 36, and the backlash between the two can be eliminated to avoid the vibration of the shaft 32. Even when the degree of opening between the valve plug 34 and the valve port 242 is small, the shaft 32 does not vibrate.

The water flow detecting assembly 38 includes a base 381, an impeller 382, a magnetic body 384 and a Hall element 386. The base 381 is disposed in the water inlet pipe section 22, and the impeller 382 is pivoted on the base. The magnetic body 384 is disposed on the impeller 382. The Hall element 386 is disposed at a position corresponding to the impeller 382 outside the water inlet pipe section 22. When the water flow is flowing, the water flow will drive the impeller 382 to rotate. When the magnetic body 384 approaches the Hall element 386, the Hall element 386 can sense the magnetic force change and output the relative electrical signal, so that the electric signal can be obtained. The change in the impeller 382 is known as the basis for the calculation of the water flow rate. The water temperature detector 40 is disposed at the inlet pipe section 22 and located at the through hole 226, so that the water in the inlet pipe section can be directly contacted to measure the water temperature in the inlet pipe section.

In summary, the water regulating valve of the present invention can effectively prevent the shaft from vibrating when the water flows through the valve port, so that the water heater can be prevented from resonating. In addition, the water regulating valve of the present invention integrates the water flow detecting component and the water temperature detector into one body, thereby increasing the convenience of the water heater installation.

The above is only a preferred embodiment of the present invention, and equivalent changes to the scope of the present application and the scope of the patent application are intended to be included in the scope of the present patent.
