Description

Temperature-sensitive water-saving water valve

technical field

The utility model relates to a water valve, in particular to a temperature-sensing water-saving and temperature-sensing anti-scalding water valve.

Background technique

There is usually a long pipe between the hot water source and the faucet and shower. When people need to use hot water through the faucet or shower, they usually need to open the valve of the faucet or shower to let the cold water in the pipe drain out. Bathing or washing is not started until the hot water from the hot water source flows to the faucet or the shower. However, it is difficult for people to grasp the timing of starting to use it, because it is difficult to confirm when the faucets and showers start to flow hot water. If you keep trying to control the water temperature with your hands, touching cold water with your hands in cold winter will make people feel uncomfortable. If you wait for a long time before using it, it is possible that the faucets and showers have been running hot water for a while, resulting in a certain degree of waste. The water valve can discharge water only when the water valve is pressed when the temperature is high, which prevents the occurrence of scalds.

Utility model content

The utility model provides a temperature-sensing water-saving water valve, the main purpose of which is to overcome the problem that it is difficult for people to grasp and control the time when the water from the faucet or the shower changes from cold water to hot water when using the faucet and the shower, and to prevent scald.

The utility model adopts the following technical solutions:

Push lever in initial position.

For the aforementioned temperature-sensitive water-saving water valve, a sealing seat is provided in the water channel, and the sealing seat is provided with a water hole communicating with the water channel. The water hole consists of an axial part and a radial part. A part communicates with an end surface of the sealing seat, the piston is arranged on one side of the end surface, a piston rod is penetrated in the axial direction of the sealing seat, one end of the piston rod is connected with the piston, and the other end is connected with a button. The first spring clip is arranged between the button and the sealing seat, and the button is exposed on the surface of the valve body.

The temperature-sensing rod includes a casing, the casing has an opening, a push rod is arranged in the opening, and a temperature-sensing material is installed in the casing.

When the piston blocks the water passage hole of the sealing seat, the block of the piston is located above the upper end of the linkage rod.

From the above description of the structure of the utility model, it can be seen that compared with the prior art, the utility model has the following advantages: when the water temperature is low, the water valve is in a conduction state, and when the water temperature rises to a certain value, the temperature sensing rod drives The linkage rod moves away from the block of the piston, so that the piston blocks the water channel, thereby closing the water valve. Therefore, the water valve has the advantage of shutting off in time after the cold water in the pipeline is discharged to prevent hot water from flowing out and causing waste. And prevent burns.

Detailed ways

The specific embodiment of the utility model is described below with reference to accompanying drawing.

The temperature-sensitive water-saving water valve, referring to Fig. 1, its main structure includes a valve body 1 and a water stop mechanism and a self-closing mechanism in the valve body 1, the valve body 1 has a water channel 10 through which water flows from bottom to top and The water inlet 101 and the water outlet 102 are located at the lower and upper ends of the water channel 10 .

Referring to FIG. 1 and FIG. 4 , the water stop mechanism mainly includes a piston 21 and a linkage rod 22 . A seal seat 25 is provided near the water outlet 102 on the upper half of the 10 water channels. The axial direction of the seal seat 25 is located in the horizontal direction. The two ends of the axial direction are two end faces. The water hole 250 of 10, the water hole 250 is composed of an axial part and a radial part, the axial part communicates with an end face of the sealing seat 25, and the radial part communicates with the side surface of the sealing seat 25, The piston 21 is arranged on one side of the end face communicating with the axial part of the water hole 250, and a piston rod 212 runs through the axial direction of the sealing seat 25, and one end of the piston rod 212 is connected to the piston 21, and the other end is connected to the piston rod 212. There is a button 24, a first spring 23 is interposed between the button 24 and the sealing seat 25, and the button 24 is exposed on the surface of the valve body 1.

Referring to Figures 1 and 4, a fixed seat 32 is provided at the middle and lower part of the valve body 1, and the linkage rod 22 is fitted on the fixed seat 32 so as to slide up and down. The water inlet 101 above the valve body 1 passes through one end The cover 12 is equipped with a water inlet connection 11 . A second spring 33 is provided between the water inlet joint 11 and the lower end of the linkage rod 22 . The piston 21 is provided with a block 211, and the linkage rod 22 is clamped on the side of the block 211 facing the sealing seat 25 when it is in the initial position. As shown in FIG. 1, the linkage rod 22 is in the At the initial position, it is clamped on the right side of the clamping block 211 .
