Abstract

The utility model relates to a triangular valve, which is used for a wash basin, showers, and inlets of water closets in washrooms. The utility model is composed of a valve body, a valve core, a handwheel, etc., wherein the valve core is driven by the handwheel to rotate. The valve body is provided with a water supply connector and an outlet connector, a pipe connecting chamber of the outlet connector is composed of a columnar inner pipe and a columnar outer pipe, wherein the pipe connecting chamber is matched with a water discharging pipe, and a sealing ring is arranged on the outer wall of the inner pipe. A screw thread on the outer wall of the outer pipe is matched with a screw nut, and a spring ring is arranged in the screw nut. The utility model is characterized in that both the inner side and the outer side of the water pipe can be clamped by the triangular valve, and the utility model has the advantages of high firmness, strong sealing performance, easy and labor-saving installation, etc.

Description

Triangle vavle

The utility model relates to valve, particularly relates to the waterworks valve, mainly is applicable to the control under the tanks such as the groove that washes one's face, instant shower heater, water closet.

In inlet channels such as the groove that washes one's face of toilet, shower, water closet, need to install triangle vavle usually.The essential structure of triangle vavle is valve body and spool, and the handwheel of water supply connector, water output connector and drive spool is arranged on the valve body.The water output connector of existing triangle vavle connects rubber pipe or metal tube, owing to be subjected to the influence of hot water high temperature, rubber pipe is aging easily, breaks and leaks, and need change, and rubber pipe water outlet have smell flavor generally at 3-5 working life.And metal tube gets rusty easily, and trouble is installed.Therefore, on the water output connector of triangle vavle, use at present the plastic-aluminum pipe gradually instead, but the performance of plastic-aluminum pipe and connection request are different from rubber pipe or metal tube, so the water output connector to triangle vavle needs to improve, but structurally there is defective in existing improved joint, mechanical sealing performance is poor, and trouble is installed, and does not still have the triangle vavle of desirable connection plastic-aluminum water pipe so far.

The purpose of this utility model provides a kind of triangle vavle, rises outside the liner and squeezes connecting water pipe in the water output connector of triangle vavle, and two-way clamping be particularly suitable for plastic pipe and connect, and assembly tool is simple, and is very convenient again, reliable sealing water channel triangle vavle.

The art designs scheme of the utility model triangle vavle is: the institutes such as handwheel by valve body and spool and drive valve core rotation form, water supply connector and water output connector are arranged on the valve body, its so-called water output connector has the interior pipe and the outer tube of cylinder type, between inner and outer pipe, constitute and take over the chamber, take over the chamber and match, on the outer wall of interior pipe, seal ring is installed, be shaped on screw thread at the outer wall of outer tube with outlet pipe, screw thread matches with tightening nut, mounting spring circle in nut.

Triangle vavle of the present utility model, its so-called spring ring are shaped on tilted conical surface in the upper/lower terminal outside, be shaped on corresponding inclined hole face on the outer tube wall of the endoporus top of nut and joint, and the inclined hole face matches with tilted conical surface.

The utility model discloses a kind of waterworks triangle vavle, water output connector to triangle vavle has carried out improving design, the interior pipe of joint inserts and connects in the water pipe, the outer tube of joint is embraced outside water pipe, like this, the plastic-aluminum water pipe is just in time installed in adapter chamber between the outer tube, when tightening nut is tightened, and the extrusion spring circle, one end of spring ring is inserted between outer tube and the water pipe, pipe inner wall is being served as a contrast by pipe in the joint prop up, pipe outer wall is tightened by spring ring, in, fold outward, the most suitable for plastics or plastic-aluminum water pipe, very firm, good seal performance only needs one spanner during installation, instrument is simple, and operation is very easy.Used the plastic-aluminum pipe, can reach more than 20 years working life.

Below in conjunction with Fig. 1-Fig. 5 embodiment of the present utility model is done detailed explanation.

The utility model relates to a kind of triangle vavle, is mainly used on the intake pipe that is connected the groove that washes one's face, shower and water closet etc.The valve body 2 of triangle vavle, the handwheel 1 that drives spool and water supply connector 3 are similar in appearance to prior art, and main improvement design is a water output connector 4.The structure of water output connector as shown in Figure 1 and Figure 2, interior pipe 6 and outer tube 5 by two cylinder types are formed, be adapter chamber 16 between the inner and outer pipe, on the outer wall of interior pipe 6 seal groove 14 is arranged, be used to install seal ring 9, take over chamber 16 water pipe 10 is installed, as the plastic-aluminum water pipe, pipe 6 inserts in water pipe 10 endoporus like this, and outer tube 5 is equivalent to embrace the outer wall at water pipe 10.Be shaped on inclined hole face 15 at the oral area (outer tube wall mouth) of taking over chamber 16, as shown in Figure 2, inclined hole face 17 is also arranged at the endoporus top at nut 8, as shown in Figure 3, a spring ring 7 is arranged again, as Fig. 1, Fig. 4, shown in Figure 5, on the spring ring 7, the outside, following two ends is shaped on tilted conical surface 11,12, as Fig. 1, shown in Figure 4, to go up tilted conical surface 11 during assembling and cooperate with nut 8 inclined hole faces 17, following tilted conical surface 12 cooperates with outer tube 5 inclined hole faces 15, spring ring 7 has an opening 18, when nut 8 was tightened with the screw thread 13 of outer tube 5, spring ring tilted conical surface 12 inserted as pin between water pipe 10 and the outer tube 5, and pipe 6 offsets in having in the water pipe 10, not to be stowed under heavy cargo not, in, outer clamp very firmly, sealability is strong, is the current ideal product that cooperates with the plastic-aluminum water pipe.Triangle vavle is made all size model, can match with the plastic-aluminum pipe of 10-25mm and other various internal diameters.
