Description
Technical field
The utility model relates to a kind of switch spool, particularly a kind of switch spool that is used on the constant-temperature tap.
Background technique
Normally used on the market at present constant-temperature tap inside is provided with two spools usually, one is the temperature regulation spool, one is the flow switch spool, for the constant-temperature tap that is installed on the solar water heater, because cold water pressure is 5～10 times of heat hydraulic pressure often, so existing constant-temperature tap flows backwards in hot-water line in order to prevent cold water, usually safety check to be installed on water intake, thereby guarantee that cold water can not enter in the solar water heater, influence the heating power of solar water heater, install after the safety check, because cold, pressure difference between the hot water is bigger, thereby has had a strong impact on the flow of hot water, after pressure difference acquires a certain degree, hot water can't pass in and out faucet subject simply, makes constant-temperature tap lose temperature adjustment function, thereby is difficult to satisfy people's usage requirement; And existing flow switch spool is arranged on the mixing water water outlet of constant-temperature tap usually, so when cold water pipe keeped in repair, hot-water line was still intake, thereby scalds the maintenance man easily.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of switch spool easy to use on the constant-temperature tap that is applied to.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of switch spool that is used on the constant-temperature tap, it comprise mutual sealing combination on, following valve body, have hot water inlet on the described upper valve body, sealing is plugged with valve rod in the upper valve body, the valve rod lower end is passed quiet valve block and is connected on the moving valve plate by shift fork, moving valve plate and the applying sealed to each other of quiet valve block, can be complementary with the through hole on the quiet valve block being provided with opening on the moving valve plate, described moving valve plate combines with the commentaries on classics core, following valve body side has the hot water outlet that communicates with the upper valve body cavity, be disposed with sealing gasket from the bottom up in the valve body under described, stable ceramic piece, dynamic porcelain piece, described dynamic porcelain piece is connected to be changeed on the core, the sealing that slides over each other of dynamic porcelain piece and stable ceramic piece, and described stable ceramic piece is provided with the water port, dynamic porcelain piece is provided with the osculum that communicates with the water port, and following valve body side has the water outlet that communicates with the inner chamber of following valve body;
As improvement of the technical scheme, described upper valve body is provided with the pressure cap that compresses valve rod; Be provided with pad between described dynamic porcelain piece and the commentaries on classics core.
The beneficial effects of the utility model are: this product need not be installed safety check on water intake, can both realize preventing that the situation that cold water flows backwards from occurring in hot-water line, thereby reach easy for installation, effectively lower the purpose of product cost, can be widely used in the constant-temperature tap on the solar water heater.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a user mode cut-away view of the present utility model.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of switch spool that is used on the constant-temperature tap, it comprise mutual sealing combination on, following valve body 1,2, have hot water inlet 11 on the described upper valve body 1, sealing is plugged with valve rod 3 in the upper valve body 1, for valve rod 3 is fixed in the upper valve body 1 better, described upper valve body 1 is provided with the pressure cap 10 that compresses valve rod 3, valve rod 3 lower ends are passed quiet valve block 4 and are connected on the moving valve plate 5 by shift fork, moving valve plate 5 and quiet valve block 4 applyings sealed to each other, can be complementary with the through hole 41 on the quiet valve block 4 being provided with opening 51 on the moving valve plate 5, described moving valve plate 5 combines with commentaries on classics core 6, following valve body 2 sides have the hot water outlet 21 that communicates with upper valve body 1 cavity, be disposed with sealing gasket 7 from the bottom up in the valve body 2 under described, stable ceramic piece 8, dynamic porcelain piece 9, described dynamic porcelain piece 9 be connected to change core 6 ' on, in order to make the sealing effect of product better, be provided with pad 61 between described dynamic porcelain piece 9 and the commentaries on classics core 6; The sealing that slides over each other of dynamic porcelain piece 9 and stable ceramic piece 8, described stable ceramic piece 8 is provided with water port 81, and dynamic porcelain piece 9 is provided with the osculum 91 that communicates with water port 81, and following valve body 2 sides have the water outlet 22 that communicates with the inner chamber of following valve body 2.
The working principle of this product is: with reference to Fig. 2, when valve rod 3 is rotated, valve rod 3 drives moving valve plates 5 and rotates and make the opening 51 on the moving valve plate 5 be complementary with through hole 41 on the quiet valve block 4, thereby make hot water enter upper valve body 1 inner chamber from the hot water inlet 11 on the upper valve body 1, respectively by through hole 41 and opening 51 and hot water outlet 21 outflows from descending valve body 2, hot water enters the temperature regulation spool through faucet subject, through with cold water mix after enter down valve body 2 from switch spool bottom, because when valve rod 3 rotates, moving valve plate 5 drives changes core 6 motions, thereby the osculum 91 on the drive dynamic porcelain piece 9 communicates with the water port 81 on the stable ceramic piece 8, and last mixing water is through water port 81, osculum 91 is from lower outlet 23 outflows of valve body 2 down.
This product need not be installed safety check on water intake, can both realize preventing that the situation that cold water flows backwards in hot-water line from occurring, thereby reaches easy for installation, effectively lower the purpose of product cost; And this switch spool is arranged on the water inlet of the hot-water line of tap, it is the control hot water flow effectively, when carrying out the tap maintenance, need only just can prevent effectively that hot water from entering faucet subject by the off switch spool, guaranteed the maintenance safety of product, this product also have governing speed soon, not only convenient but also reduced the waste of water resources in the temperature adjustment process, the characteristics that water-saving result is good, thus can be widely used in constant-temperature tap on the solar water heater.
