Description
Technical field
The utility model relates to a kind of valve for controlling fluid flow in pipeline, particularly relates to a kind of anti-freezing valve of water pipe.
Background technique
In the north, winter, comparatively arctic weather temperature can drop to subzero, and in order to the convenience used, many valves and the pipeline be connected with valve can be arranged on open air, even if valve is in closed condition, still have part water in the pipeline be connected with valve, when temperature is down to zero following, the water in pipeline and in valve can freeze, valve is caused to freeze, after freezing, the volume of water increases, and the pipeline of valve and connection is split up by serious meeting, affects the use of valve.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of pipeline preventing valve and be connected with valve and freezes the anti-freezing valve of water pipe be even split up.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of anti-freezing valve of water pipe, the spool comprising valve body and be arranged in valve body and valve rod, described valve rod is arranged on the upper end of spool, described valve rod one end extends to the outside of valve body, be fixedly connected with the handle be positioned at above valve body, described valve body is provided with water intake and water outlet, separately there are intake pipe and outlet pipe by the intracavity inter-connection of water intake and water outlet and valve body, the tube wall of described intake pipe is provided with opening, opening installs anti-icer, described anti-icer comprises the rubber pad being sealed in opening inner side and the sensory package be arranged on outside rubber pad, described sensory package comprises sensing block and is arranged on the sensing probe of sensing block upper end, sensor is separately had to be fixedly installed on above sensing probe by support, gap is provided with between the end of described sensing probe and the switch of sensor, the outside parcel electric heating cover of described intake pipe and outlet pipe, described sensor is connected with the control gear of electric heating cover by electric wire.
As preferred technological scheme, the longitudinal section of described rubber pad is U-shaped, and the interior recess of U-shaped is positioned at inside intake pipe, and described sensory package is fixedly connected on the interior recess of rubber pad.
Owing to have employed technique scheme, a kind of anti-freezing valve of water pipe described in the utility model utilizes the principle of volumetric expansion after water freezing, promote sensing probe start sensor switch, thus electric heating cover is heated the water frozen in pipeline, avoid being split up water pipe, due to thermal conductivity, the water in valve cavity is heated equally, is arranged on outdoor pipe when this valve is applicable to cold in winter.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of the utility model intake pipe part.
Embodiment
As shown in Figure 1, a kind of anti-freezing valve of water pipe, comprise valve body 1 and the spool 2 be arranged in valve body 1 and valve rod 3, described valve body 1 is hollow casing shape, described spool 2 is arranged in the inner chamber of valve body 1, and the inner chamber of valve body 1 is divided into two chambers by spool 2, described valve rod 3 is arranged on the upper end of spool 2, described valve rod 3 is vertically arranged in valve body 1, described valve rod 3 one end extends to the outside of valve body 1, be fixedly connected with the handle 11 be positioned at above valve body 1, by the unlatching of handle 11 with movable valve plug 2, described valve body 1 is provided with water intake and water outlet, separately there are intake pipe 5 and outlet pipe 6 by the intracavity inter-connection of water intake and water outlet and valve body 1, described water intake and water outlet lay respectively in two chambers of spool 2 both sides.
As shown in Figure 2, the tube wall of described intake pipe 5 is provided with opening, opening installs anti-icer, described opening is arranged on the upper end of tube wall, be convenient to the installation of anti-icer, described anti-icer comprises the rubber pad 4 being sealed in opening inner side and the sensory package be arranged on outside rubber pad 4, described rubber pad 4 is sealed in opening and prevents the water in pipeline from spilling, the outer rim longitudinal section of described rubber pad 4 takes the shape of the letter U, the sidewall of described opening is installed between the two side of U-shaped outer rim, when the water freezing in pipeline expands, rubber pad 4 sidewall being positioned at opening inner side plays buffer function, rubber pad 4 is avoided to come off, the longitudinal section of described rubber pad 4 is U-shaped, and the interior recess of U-shaped is positioned at inside intake pipe 5, described sensory package comprises sensing block 7 and is arranged on the sensing probe 8 of sensing block 7 upper end, described sensing block is fixedly connected on the interior recess of rubber pad 4, sensing probe 8 is vertically arranged, and the top of sensing probe 8 extends to the outside of rubber pad 4, sensor 9 is separately had to be fixedly installed on above sensing probe 8 by support, gap is provided with between the end of described sensing probe 8 and the switch of sensor 9, the outside parcel electric heating cover 10 of described intake pipe 5 and outlet pipe 6, described sensor 9 is connected by the control gear of electric wire with electric heating cover 10, described heating resistance collar 10 also can be wrapped in the outside of valve body 1, the inner chamber of valve body 1 is heated.
When winter makes outdoor temperature is reduced to subzero, the water being positioned at intake pipe 5 and outlet pipe 6 can freeze, volumetric expansion after freezing, and the bottom promoting rubber pad 4 moves upward, thus make sensing probe 8 feeler 9 switch, sensor 9 sends signal to electric heating cover 10, and the inner chamber of electric heating cover 10 pairs of intake pipes 5 and outlet pipe 6 heats, and avoids water continuation to freeze and is split up pipeline, simultaneously, under heat conducting effect, in the inner chamber of valve body 1, water is heated equally, realizes valve entirety antifreeze.
