Abstract
The utility model discloses a back-water valve, which is characterized in that the valve body is equipped with a water inlet, a water outlet and a water-back port; a cock is arranged inside the cavity of the valve body, the cock is equipped with a through on-off hole, the axis of the water inlet end of the on-off hole forms an angle with that of the water outlet end of the on-off hole; the angle is identical to an angle formed between the water inlet and the water outlet on the valve body and an angle formed between the water outlet and the water-back port; and the cock is connected with a screwing rod. The back-water valve is capable of controlling water outlet, water stop and water back through the screwing rod, has simple structure, convenient operation and good water sealing property, and can effectively prevent water outlet pipelines freezing.
Description
Technical field
The utility model relates to a kind of valve, particularly a kind of backwater valve.
Background technique
In winter, at vast northern country, the outdoor tap water pipe freezes layer and influenced by low temperature and consecutive low temperature with top, and conduit pipeline freezes easily, the water intaking difficulty.For antifreeze, generally adopt the backwater measure, be about to water in the outlet conduit and be back to and do not freeze layer, at present, general employing two valves of backwater of cutting off the water are earlier again operated more loaded down with trivial detailsly, and corresponding establishment is also many.
The model utility content
The utility model technical issues that need to address provide a kind ofly integrate water outlet, cut off the water, the backwater valve of backwater.
For addressing the above problem, technical solution adopted in the utility model is: a kind of backwater valve, it is characterized in that, valve body is provided with water intake, water outlet and backwater mouth, body cavity is provided with a cock, offers the keying hole of perforation in the cock, and there are an angle in the water inlet, the waterexit end axis that open and close the hole, on this angle and the valve body angle of entery and delivery port and go out, the corner dimension of backwater mouth all equates, connects a swing arm in the cock.
The angle of described entery and delivery port and go out, the angle of backwater mouth is 120 °, described swing arm is perpendicular to plane, entry, exit, back outlet place.
The angle of described entery and delivery port and go out, the angle of backwater mouth is 90 °, described swing arm and water outlet angle are 180 °.
Described cock is spherical.
Be provided with packing ring and catch between described water intake, water outlet and backwater mouth and cock.
Offer the hole identical on the described catch, and overlap with the keying hole with opening and closing hole size.
Adopt the beneficial effect that technique scheme produced to be: this novel by swing arm be the may command water outlet, cut off the water, backwater, simple structure, easy to operate, water seal is good, can prevent effectively that outlet conduit from freezing.
Description of drawings
Fig. 1 is the utility model embodiment one a sectional structure schematic representation;
Fig. 2 is the utility model embodiment one a schematic appearance;
Fig. 3 is the utility model embodiment two a sectional structure schematic representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Embodiment one
As depicted in figs. 1 and 2, the utility model valve body is provided with water intake 1, water outlet 3 and backwater mouth 5, body cavity is provided with a cock 2, cock 2 is spherical, offer the keying hole 4 of perforation on it, there are an angle in the water inlet, the waterexit end axis that open and close hole 4, and this angle is 120 °, the angle of the angle of water intake 1, water outlet 3 and water outlet 3, backwater mouth 5 also is 120 °, and 2 connect a swing arm 6 in the cock.Described swing arm 6 is perpendicular to water intake 1, water outlet 3, plane, backwater mouth 5 place.2 of water intake 1, water outlet 3 and backwater mouth 5 and cocks are provided with packing ring and catch, play seal action, offer and open and close the identical hole of 4 sizes, hole on the catch, and overlap with the keying hole.
When keying hole 4 communicated with water outlet 3 and backwater mouth 5 respectively, residual water was back to by refluxing opening 5 and does not freeze layer in the outlet conduit, had prevented that effectively water from freezing in outlet conduit.
Embodiment two
As shown in Figure 3, the utility model valve body is provided with water intake 1, water outlet 3 and backwater mouth 5, body cavity is provided with a cock 2, cock 2 is spherical, offers the keying hole 4 of perforation on it, and there are an angle in the water inlet, the waterexit end axis that open and close hole 4, this angle is 90 °, the angle of the angle of water intake 1, water outlet 3 and water outlet 3, backwater mouth 5 also is 90 °, and 2 connect a swing arm 6 in the cock, and swing arm 6 is 180 ° with the angle of water outlet 3.4 of water intake 1, water outlet 3 and backwater mouth 5 and cocks are provided with packing ring and catch, play seal action, offer and open and close the identical hole of 4 sizes, hole on the catch, and overlap with the keying hole.
When keying hole 4 communicated with water outlet 3 and backwater mouth 5 respectively, residual water was back to by refluxing opening 5 and does not freeze layer in the outlet conduit, had prevented that effectively water from freezing in outlet conduit.
