Abstract

The utility model relates to an automatic opening and closing water discharging temperature control structure, comprising a pipe body and a pipe plug, wherein, one end of the pipe body is connected with a warm water source, and the end face of the other end of the pipe body is provided with a through hole; the pipe plug is covered and combined on the through hole, and the center of the pipe plug is connected with a rod body with a tail end which can be screwed with a screw cap; the rod body extends into the pipe body through the through hole and a set of bimetal slices which are locked and positioned by the screw cap is arranged on the rod body. The utility model has the advantages of simple structure, reliable motion, etc., and the utility model is especially suitable for equipment such as drain valves, water heaters, etc. which are required to control the water temperature of a water outlet can also be used as an experimental appliance for teaching experiments.

Description

The water-exit temperature control structure of automatic on-off

The utility model relates to valve, is a kind of temperature controlling device in order to the control water-exit temperature.

In existing steam, hot-water heating system, extensively adopt drain valve, drain valve for example just is housed in caliduct, the effect of drain valve is to emit unnecessary condensed water, daily " bump, the bump " Strike note that sends in the caliduct of hearing is exactly the sound that drain valve sends.Drain valve why can send sound like this sound this be because ducted steam is constantly condensed into water, the temperature at drain valve place is constantly reduced after flowing to drain valve, when it dropped to certain temperature value, drain valve was just opened, and emitted condensed water; When reaching another higher temperature value behind the temperature recovery at drain valve place, drain valve is auto-closing just, sends " bump, bump " sound.Why drain valve can the another kind of occasion of automatic on-off be, in hot water supply system, a kind of water-exit temperature control gear simple in structure, reliable preferably can be arranged, for example, in water heater, this device preferably is housed, make and can connect heating source automatically when water-exit temperature is low, to improve water-exit temperature, when water-exit temperature is too high, can cut off heating source automatically.Which type of device can use in water heater

The purpose of this utility model provides a kind of water-exit temperature control structure of energy automatic on-off, make it when water-exit temperature hangs down to a certain setting value, to open water outlet (drain valve in caliduct) automatically, or connect heating source (using in water heater) automatically; When water-exit temperature is higher than a certain setting value, can close water outlet automatically, or cut off heating source automatically.

Realize the utility model of above-mentioned purpose, include a body and a pipe close, body one end links to each other with the warm water water source.Have a through hole on the end face of the other end, pipe close covers on this through hole, and characteristics of the present utility model are to be connected with the body of rod that its tail end can screw togather nut at the pipe close center, this body of rod via through holes is stretched and is inserted in the pipe close, and is equipped with one group of bimetallic strip with the nut locking and positioning on this body of rod.

Above-mentioned the utility model, because bimetallic strip is a kind of temperature memory element, when range of temperature surpassed setting value, bimetallic strip promptly deformed, the functional element that is attached thereto then realizes controlling purpose thereupon producing displacement.The utlity model has advantages such as simple in structure, reliable in action, be particularly suitable for using in the equipment such as drain valve in needs control water outlet water temperature, water heater, also can be used as a kind of experiment utensil that education experiment is used.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Embodiment of the present utility model as shown in drawings.See by figure, the utility model includes a body 1 and a pipe close 6, body 1 one ends link to each other with the warm water water source, have a through hole 5 on the face of the other end, pipe close 6 covers on this through hole 5, pipe close 6 centers are connected with the body of rod 4 that its tail end can screw togather nut 2, and these body of rod 4 via through holes 5 are stretched and inserted in the body 1, and are provided with one group of bimetallic strip 3 with nut 2 locking and positioning on this body of rod 4.

Claims

1, a kind of water-exit temperature control structure of automatic on-off, include a body and a pipe close, body one end links to each other with the warm water water source, have a through hole on the end face of the other end, pipe close covers on this through hole, it is characterized in that: the pipe close center is connected with the body of rod that its tail end can screw togather nut, this body of rod via through holes is stretched and is inserted in the body, and is provided with one group of bimetallic strip with the nut locking and positioning on this body of rod.
