Description

Diaphragm flush valve with electric control function

The present invention relates to a valve device, in particular to a diaphragm flush valve with electric control function that can be easily installed and can save time and money for refitting.

Diaphragm flush valves are often installed in public toilets and used with urinals or squatting or sitting toilets. As shown in Figures 8 and 9, the existing diaphragm flush valve includes a main body 70, A diaphragm pressure relief assembly 80 and a manual assembly 90; wherein the diaphragm pressure relief assembly 80 and the manual assembly 90 are provided with the main body 70.

The main body 70 includes a water outlet pipe 71 and a water inlet port 72. The water outlet pipe 71 includes a water outlet end and a flushing end opposite to each other. The water inlet port 72 communicates with the water outlet end of the water outlet pipe 71 and is connected to a water supply. The sources are connected.

The diaphragm pressure relief assembly 80 includes a guide 81, a valve head limiting member 82, a pressure relief valve 83, a diaphragm valve 84, and a seal 85; wherein the guide 81 is tubular and penetrates The valve head restricting member 82 is fixed to the guide member 81 and is close to the water outlet end of the water outlet pipe 71. The valve head restricting member 82 includes a perforation 821 communicating with the inside of the guide member 81.

The pressure relief valve 83 is mounted on the valve head limiting member 82 and includes a valve head 831 and a valve stem 832, the valve head 831 stops the perforation 821, the valve stem 832 is coupled to the valve head 831, and the valve The rod 832 passes through the perforation 821 and the guide 81 and extends into the water outlet pipe 71. The diaphragm valve 84 is annular and is sleeved on the guide 81. The diaphragm valve 84 is interposed by the valve head. Between the member 82 and the water outlet end of the water outlet pipe 71, the diaphragm valve 84 is elastic and the middle portion of the diaphragm valve 84 can be ridged upward, so that the water inlet 72 is connected to the water outlet end of the water outlet pipe 71 Through or recessed down to block the water inlet 72 and the water outlet pipe At the water outlet end of 71, the diaphragm valve 84 is provided with a plurality of communication holes 841 penetrating therethrough, and the plurality of communication holes 841 are arranged around the guide member 81.

The seal 85 is made of rubber or silicone and is disposed above the pressure relief valve 83. A water storage space S1 is formed between the seal 85 and the valve head restriction 82, and the water storage space S1 passes through the A plurality of communication holes 841 communicate with the water inlet 72.

The manual assembly 90 includes a handle 91 located outside the main body 70 and a push rod 92 coupled to the handle 91. The push rod 92 penetrates the main body 70.

The fresh water introduced from the water supply source passes through the plurality of communication holes 841 of the diaphragm valve 84 to enter the water storage space S1, and the fresh water applies pressure to the diaphragm valve 84, so that the middle portion of the diaphragm valve 84 faces The depression is blocked to prevent the water inlet 72 from communicating with the water outlet of the water outlet pipe 71.

When the user pulls the handle 91, the push rod 92 penetrating the main body 70 pushes against the valve rod 832, so that the valve head 831 no longer stops the perforation 821, and the clear water in the water storage space S1 flows through The perforation 821 enters the guide 81, and then flows out through the flushing end of the water outlet pipe 71. When the water storage space S1 cannot provide pressure on the diaphragm valve 84, the middle portion of the diaphragm valve 84 is ridged upward. Therefore, the water inlet 72 is communicated with the water outlet end of the water outlet pipe 71, and the clear water introduced from the water supply source can be directly introduced into the water outlet pipe 71 and washed out with a large flow rate.

However, in order to improve the convenience of the flush valve, more and more places have been changed to inductive flush valves; moreover, the inductive flush valve can prevent users from directly contacting the flush valve. It is also more hygienic in use.

Time and cost; for this reason, designs such as the flush valve disclosed in US 20100024895 A1 changed from manual push rods to automatic push rods. However, this device uses a motor and a gear set to push The moving mechanism consumes a lot of power and is not environmentally friendly. In addition, there is a replacement component that replaces the upper part of the manual flush valve with the pressure relief component. Although the coil valve is used to switch water, it has the effect of saving power, but it cannot be retained The original pressure relief component parts and the unique functions of the pressure relief component cannot retain manual functions, resulting in a dilemma of limited functions and increased parts. It can be seen that in order to replace a few parts, the existing flush valve using manual operation is retrofitted with minimal cost in a short period of time and retains the function of the original pressure relief component. The existing flush valve needs to be changed in structure. And improvement.
