Abstract
The invention aims at providing an overheating protecting valve to limit temperature of outlet water and guarantee that temperature of the outlet water is not too high. The overheating protecting valve comprises a valve body. The valve body is provided with a cold water inlet pipe, a hot water inlet pipe and a water outlet pipe. The cold water inlet pipe and the hot water inlet pipe are respectively provided with a regulating valve core, wherein the regulating valve core can regulate flow. A function cavity is formed in the lateral portion of the water outlet pipe. An expansion cavity, a spring and a protective valve core are installed in the function cavity. Expansion liquid is filled in the expansion cavity. One end of the protective valve core penetrates through the lateral wall of the water outlet pipe so as to stretch into the water outlet pipe and the other end of the protective valve core penetrates through the top wall of the function cavity so as to stretch out of the function cavity. One lateral wall of the expansion is a rubber membrane. The pulling rod is fixed in the function cavity through a spindle. One end of the pulling rod butts against the rubber membrane and the other end of the pulling rod butts against the lateral wall of the protective valve core. A concave pit is formed in the lateral wall of one side of the protective valve core and the concave pit is matched with the pulling rod. The spring is sleeved on the protective valve core. One end of the spring is connected with the water outlet pipe and the other end of the spring is connected with a protruded portion, wherein the protruded portion is installed on the lateral wall of the protective valve core.
Description
Technical field
The invention belongs to valve technology field, specially refer to a kind of overtemperature protection valve.
Background technique
Now home-use water heater is all that the pipeline by separately is incorporated into the valve place with cold water and hot water, controls respectively the flow of cold water and hot water by valve and controls the ratio of cold water and the hot water of water outlet place, thereby adjust the temperature of water outlet.But in use, the ratio of cold water and hot water does not regulate sometimes, and the too high and situation of scalding of water-exit temperature can occur.
Summary of the invention
The objective of the invention is to propose a kind of overtemperature protection valve, with the temperature of restriction water outlet, guarantee that water-exit temperature can be not too high.
Overtemperature protection valve of the present invention comprises valve body, described valve body is provided with cold water inlet, hot water inlet pipe and outlet pipe, described cold water inlet, hot water inlet pipe are equipped with the regulating spool of adjust flux, key is that the sidepiece of described outlet pipe is provided with a function chamber, be provided with expansion chamber, spring, pull bar and protection spool in described function chamber, in described expansion chamber, swelling liquid be housed; One end of described protection spool passes the sidewall of outlet pipe and stretches in outlet pipe, and the other end passes the roof in function chamber and stretches out outside the function chamber; One side sidewall of described expansion chamber is rubber membrane, and described pull bar is fixed in the function chamber by rotating shaft, and an end and the rubber membrane of pull bar offset, and the other end offsets with the sidewall of protection spool, and the sidewall of described protection spool is provided with the pit that coordinates with pull bar; Described spring is placed on the Protective valve core, and an end of spring is connected with outlet pipe, and the other end protuberance set with protecting the spool sidewall is connected.
In use; at first pull with hand the protection spool; make the protection spool overcome the pulling force of spring and move along the direction perpendicular to outlet pipe; thereby the end that makes pull bar snaps in the pit of protection spool sidewall just; unclamp hand this moment; because pull bar snaps in pit, the elastic force of spring can't make the protection spool move, so outlet pipe is held open state.After the water temperature of outlet pipe raises; the swelling liquid of expansion chamber constantly expands because of the volume that is heated; the rubber membrane that drives the expansion chamber sidewall moves; thereby pushing drawing rod rotates around its rotating shaft; after the water temperature of outlet pipe reaches predetermined temperature (for example 40 ℃); just make the end of pull bar deviate to protect the pit of spool sidewall, protect spool to move to the outlet pipe direction under the pulling force effect of spring this moment, thereby close outlet pipe.
Further, described swelling liquid is benzene, and the expansion coefficient of benzene is larger, and is very fast to the thermotonus ratio of outlet pipe.
Overtemperature protection valve of the present invention is by arranging protection spool and expansion chamber at traditional distributing valve outlet pipe place, can be when water-exit temperature be too high the autoshutdown outlet pipe, avoid scalding the user, have good practicability.
Description of drawings
Fig. 1 is the structural representation (outlet pipe unlatching) of overtemperature protection valve of the present invention.
Fig. 2 is the structural representation (outlet pipe is closed) of overtemperature protection valve of the present invention.
Embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of the specific embodiment of the present invention such as related each member, structure, each several part and annexation, each several part and working principle etc. are described in further detail.
Embodiment 1:
As shown in Figure 1, 2, the overtemperature protection valve of the present embodiment comprises valve body 1, described valve body is provided with cold water inlet 2, hot water inlet pipe 3 and outlet pipe 4, described cold water inlet 2, hot water inlet pipe 3 are equipped with the regulating spool 5 of adjust flux, key is that the sidepiece of described outlet pipe 4 is provided with a function chamber 6, be provided with pull bar 9 and the protection spool 10 of expansion chamber 7, spring 8, " Z " shape in described function chamber 6, in described expansion chamber 7, benzene be housed; One end of described protection spool 10 passes the sidewall of outlet pipe 4 and stretches in outlet pipe 4, and the other end passes the roof in function chamber 6 and stretches out outside function chamber 6; One side sidewall of described expansion chamber 7 is rubber membrane 11, described pull bar 9 is fixed in function chamber 6 by rotating shaft 14, one end and the rubber membrane 11 of pull bar 9 offset, and the other end offsets with the sidewall of protection spool 10, and the sidewall of described protection spool 10 is provided with the pit 12 that coordinates with pull bar 9; Described spring 8 is placed on protection spool 10, and an end of spring 8 is connected with outlet pipe 4, and the other end protuberance 13 set with protecting spool 10 sidewalls is connected.
As shown in Figure 1; in use; at first pull with hand protection spool 10; make protection spool 10 overcome the pulling force of spring 8 and move along the direction perpendicular to outlet pipe 4; thereby the end that makes pull bar 9 snaps in the pit 12 of protection spool sidewall just, and unclamp hand this moment, because pull bar 9 snaps in pit 12; the elastic force of spring 8 can't make protection spool 10 move, so outlet pipe 4 is held open state.
As shown in Figure 2; after the water temperature of outlet pipe 4 raises; benzene in expansion chamber 7 constantly expands because of the volume that is heated; the rubber membrane 11 that drives expansion chamber 7 sidewalls moves; thereby pushing drawing rod 9 rotates around its rotating shaft 14, after the water temperature of outlet pipe 4 reaches predetermined temperature (for example 40 ℃), just makes the end of pull bar 9 deviate to protect the pit 12 of spool 10 sidewalls; protect spool 10 to move to outlet pipe 4 directions under the pulling force effect of spring 8 this moment, thereby close outlet pipe 4.
