Water nozzle using ball valve core

Abstract

The utility model discloses a water nozzle using a ball valve core, which comprises a valve body, a valve core cavity, a valve core, a water inlet component, a water outlet component, a handle component and the like, and is mainly characterized in that the valve core adopts the ball valve core with a water through hole, and the water through hole is a straight through hole vertical to the rotating shaft axis of the ball valve core; meanwhile, a taper hole and an inner hole which are sequentially communicated are formed between the valve element cavity and the outlet end of the water nozzle, the large hole diameter of the taper hole is larger than that of the water through hole, the small hole diameter of the taper hole is the same as that of the inner hole, and the hole diameter of the inner hole is smaller than that of the water through hole. Therefore, when the handle assembly drives the ball valve element to rotate in the valve element cavity in a sealed mode, the water nozzle can be opened and closed. When the water nozzle is opened, due to the fact that a flow channel, entering the water through hole, of the inlet end is of a straight-through type, fluid obstruction and flow change are small, the flow can be kept stable, due to the fact that the straight-through hole can have the large drift diameter, the flow of the straight-through hole is relatively large, and when the straight-through hole is communicated with the outlet end through the taper hole and the inner hole in sequence, the water outlet pressure can be increased in cooperation with increase of the water outlet flow.

Description

Technical Field

[0001] The utility model relates to a water tap, in particular to a water tap using a ball valve core. Background Art

[0002] Faucets are commonly used plumbing and sanitary products in daily life. Their performance is directly related to the user's experience and also affects the user's quality of life; therefore, a faucet product with excellent performance is crucial to users. However, according to current market feedback, due to the popularity of high-rise residential buildings, the water pressure in the homes of users on higher floors is lower, and the valve cores used in existing faucets are all ceramic valve cores. Although the opening and closing sealing quality is reliable, there will be a certain flow limiting effect, which will cause the faucets in high-rise user households to have a small and unstable flow rate, and the water outlet pressure is also small. Even if a bubbler with a larger flow rate is used, the above problems cannot be effectively solved, which brings great inconvenience to the water use of high-rise users. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a water nozzle using a ball valve core with large and stable water flow and high water outlet pressure.

[0004] The technical problem of the utility model is achieved through the following technical solutions:

[0005] A water faucet using a ball valve core comprises a valve body, a water inlet assembly installed at the inlet end of the valve body, a water outlet assembly installed at the outlet end of the valve body, a valve core cavity arranged in the valve body, a valve core installed in the valve core cavity and a handle assembly arranged outside the valve body, wherein the valve core is a ball valve core, and a water through hole is arranged in the ball valve core; the valve core cavity is connected to the outlet end through a tapered hole and an inner hole, the large hole diameter of the tapered hole is larger than the hole diameter of the water through hole, the small hole diameter of the tapered hole is the same as the hole diameter of the inner hole, and the hole diameter of the inner hole is smaller than the hole diameter of the water through hole; the handle assembly drives the ball valve core to rotate in a sealed manner in the valve core cavity, and drives the water through hole to be connected with the inlet end, the tapered hole, the inner hole and the outlet end on the same axis to open the water faucet, or drives the water through hole to be perpendicular to the axis of the inlet end, the tapered hole, the inner hole and the outlet end to close the water faucet.

[0006] The water through hole is a straight through hole perpendicular to the rotation axis of the ball valve core.

[0007] The two sides of the ball valve core are respectively provided with retaining rings that fit tightly and form a dynamic seal. The retaining rings on each side are flat cylindrical gaskets made of elastic material. A through hole is provided in the middle of the retaining ring. When the water spout is opened, the water hole of the ball valve core is connected to the middle hole on the same axis.

[0008] The valve core cavity is provided with an embedding groove arranged by the large hole adjacent to the tapered hole, and the retaining ring is embedded in the embedding groove and closely fits the ball valve core.

[0009] The inlet end is provided with an internal nut connected by thread, the inner end surface of the internal nut is provided with an end groove, the retaining ring is embedded in the end groove, and is screwed inwardly through the thread of the internal nut to closely fit the ball valve core.

[0010] A limiting outer shoulder and a limiting inner shoulder are respectively arranged between the outer surface of the internal nut and the inner surface of the inlet end, and the limiting outer shoulder and the limiting inner shoulder constitute the inward tightening stroke of the thread of the internal nut.

[0011] The water inlet assembly comprises a water inlet joint which is threadedly screwed and sealed in the inlet end. A fixing seat and a tightening seat are arranged on the water inlet joint, and an installation clamp is formed between the fixing seat and the tightening seat.

[0012] Washers are respectively arranged on the opposite surfaces of the fixing seat and the tightening seat. The tightening seat is threadedly installed on the water inlet joint and the distance of the installation clamp is adjusted by screwing in or out of the thread of the fixing seat.

[0013] The water outlet assembly comprises a water outlet pipe, the end of which is sealably inserted into the outlet end, a clamping ring is provided on the outer surface of the water outlet pipe, and a movably mounted compression sleeve is provided outside the water outlet pipe. The compression sleeve is threadedly screwed onto the outlet end and drives the ring inside the compression sleeve to push the clamping ring against the outlet end to prevent the water outlet pipe from falling off.

[0014] The handle assembly comprises a valve stem rotatably mounted in the valve body, the inner end of the valve stem is transmission mounted on the ball valve core, the outer end of the valve stem is provided with a fixed handle, and the handle drives the valve stem to drive the seal of the ball valve core to rotate.

[0015] Compared with the prior art, the utility model mainly adopts a ball valve core with a water-through hole in the valve core of the faucet, and the water-through hole is a straight hole perpendicular to the rotation axis of the ball valve core; at the same time, a tapered hole and an inner hole connected in sequence are provided between the valve core cavity for installing the ball valve core and the outlet end of the faucet, and the large hole diameter of the tapered hole is larger than the hole diameter of the water-through hole, the small hole diameter of the tapered hole is the same as the hole diameter of the inner hole, and the hole diameter of the inner hole is smaller than the hole diameter of the water-through hole; in this way, when the handle assembly drives the ball valve core to rotate in a sealed manner in the valve core cavity, it will drive the water-through hole to be connected with the inlet end, the tapered hole, the inner hole, and the outlet end on the same axis to open the faucet, or drive the water-through hole to be perpendicular to the axis of the inlet end, the tapered hole, the inner hole, and the outlet end to close the faucet. Among them, when the faucet is turned on, since the flow channel from the inlet end to the water hole is a straight-through type, there is little obstruction when the fluid flows through the water hole, the flow rate changes very little, and the flow rate can be kept stable. Because the straight-through hole can have a larger diameter, its flow rate is also relatively large, which brings great convenience to the water use of high-rise users; moreover, the water hole is connected to the outlet end through the tapered hole and the inner hole in sequence. In the process of flowing in from the large hole and rapidly shrinking to flowing out from the small hole, the water outlet pressure is also increased in conjunction with the increase in the water flow rate, so it also has good adaptability to the use environment with lower water pressure.

[0024] A water tap using a ball valve core, such as Figure 1 , Figure 2 As shown, it can meet the water needs of high-rise users with lower water pressure. Its structure mainly consists of a valve body 1, a water inlet assembly 2 installed at the inlet end 11 of the valve body, a water outlet assembly 3 installed at the outlet end 12 of the valve body 1, a valve core cavity 13 arranged in the valve body 1, a valve core installed in the valve core cavity and a handle assembly 4 arranged outside the valve body 1.

[0025] The valve body 1 is a vertically arranged straight-through pipe, and the inlet end 11 is arranged Figure 1 The lower end of the valve body shown in FIG. 1 is provided with an outlet port 12 Figure 1 As shown in the upper end of the valve body, the inlet end 11 and the outlet end 12 are exactly located on the same waterway axis, and the handle assembly 4 is arranged on one side of the valve body 1.

[0026] The water inlet assembly 2 includes a water inlet connector 21, one end of the water inlet connector, i.e., the upper end, is threadedly tightened and sealed in the inlet end 11 in cooperation with an O-ring, and the other end of the water inlet connector 21, i.e., the lower end, can be externally connected to a hose for water inlet. A fixing seat 22 and a splicing seat 23 are provided on the water inlet connector 21, and washers 24 are respectively provided on the opposite surfaces of the fixing seat 22 and the splicing seat 23, and a mounting clamp 25 is formed between the fixing seat 22 and the splicing seat 23; the splicing seat 23 is threadedly installed on the water inlet connector 21, and the distance of the mounting clamp 25 is adjusted by screwing in or out of the thread relative to the fixing seat 22, thereby ensuring that the faucet can be stably installed on countertops of various thicknesses.

[0027] The water outlet assembly 3 includes a water outlet pipe 31, the end of which is sealed and inserted into the outlet end 12 through a double-channel O-ring 32, and the water outlet pipe 31 can also provide sealing performance when it rotates relative to the outlet end 12. The outer surface of the water outlet pipe 31 is provided with a clamping ring 33, one end of which is provided with an opening for easy expansion and installation. The water outlet pipe 31 is provided with a movable clamping sleeve 35 on the outside, and the clamping sleeve is threadedly screwed on the outlet end 12, which drives the ring 34 in the clamping sleeve 35 to push the clamping ring 33 installed in the expansion and expansion to press against the end of the outlet end 12 to form a stop for the water outlet pipe 31, and also serves a decorative role.

[0028] The cross section of the ferrule 34 is "L"-shaped. The "L"-shaped long end of the ferrule 34 is clamped between the water outlet pipe 31 and the clamping sleeve 35, which can reduce the shaking of the water outlet pipe 31 when it rotates. The "L"-shaped short end of the ferrule 34 is pressed by the clamping sleeve 35, and then presses the clamping ring 33. Therefore, tightening the thread of the clamping sleeve 35 at the outlet end 12 can also provide a clamping force for the ferrule 34 and the clamping ring 33.

[0029] The valve core is a ball valve core 5, which is provided with a water hole 51; the valve core cavity 13 is connected to the outlet end 12 through the tapered hole 14 and the inner hole 15, and the large hole diameter of the tapered hole 14 is larger than the hole diameter of the water hole 51, the small hole diameter of the tapered hole 14 is the same as the hole diameter of the inner hole 15, and the hole diameter of the inner hole 15 is smaller than the hole diameter of the water hole 51.

[0030] When the handle assembly 4 drives the ball valve core 5 to rotate in a sealed manner in the valve core cavity 13, the water hole 51 can be connected to the inlet end 11, the tapered hole 14, the inner hole 15, and the outlet end 12 on the same axis to open the water spout, or the water hole 51 can be connected to the axis perpendicular to the inlet end 11, the tapered hole 14, the inner hole 15 and the outlet end 12 to close the water spout. That is, the purpose of controlling the on and off of the water spout can be achieved by controlling the rotation of the handle assembly 4.

[0031] The water hole 51 is as follows Figure 4 The figure shows a straight through hole perpendicular to the axis of rotation of the ball valve core 5, so the water hole 51 is connected with the inlet end 11, the tapered hole 14, the inner hole 15, and the outlet end 12 on the same axis, which is the maximum water flow rate of the water nozzle. When the axis of the water hole 51 deviates slightly from the axis of the inlet end 11, the tapered hole 14, the inner hole 15, and the outlet end 12, the water flow rate of the water nozzle is adjusted accordingly according to the deviation angle until the water hole 51 is completely perpendicular to the axis of the inlet end 11, the tapered hole 14, the inner hole 15 and the outlet end 12, that is, the deviation angle is exactly 90°. At this time, the outer wall of the ball valve core 5 is sealed by the retaining ring 6 and the water flow is cut off, so the water nozzle can be completely closed.

[0032] The handle assembly 4 includes a valve stem 41 rotatably sealed and installed in the valve body 1. Specifically, the valve stem is rotatably sealed and installed in the side hole 18 of the valve body 1 through a double-pass O-ring formed by inserting in a double-pass annular groove 412 on the outer surface of the valve stem. Figure 1 As shown, the left end is installed in the flat groove 52 of the ball valve core 5 through the flat shaft 411, and the outer end of the valve stem 41 is fitted with the handle 42 through the spline shaft 413 and fixedly installed with the screw 43. Therefore, the valve stem 41 is driven by the handle 42 to drive the ball valve core 5 to rotate in the valve core cavity 13.

[0033] The two sides of the ball valve core 5 are respectively provided with retaining rings 6 that fit tightly and form a dynamic seal. The retaining rings on each side are flat cylindrical gaskets made of elastic material. A through hole is provided in the middle of the retaining ring 6. When the water tap is opened, the water through hole 51 of the ball valve core 5 is connected to the middle hole on the same axis.

[0034] At the same time, the installation structures of the retaining rings 6 on both sides are different. The retaining ring close to the outlet end, that is, the retaining ring 6 located on the upper side, has the following installation structure: a groove 16 is provided in the valve core cavity 13 for setting the large hole adjacent to the tapered hole 14, and the retaining ring 6 is embedded in the groove 16 and fits tightly on the spherical surface of the ball valve core 5.

[0035] The retaining ring near the inlet end, that is, the retaining ring 6 located on the lower side, has an installation structure as follows: a threaded internal nut 7 is provided inside the inlet end 11, an end groove 71 is provided on the inner end surface of the internal nut, and the retaining ring 6 is embedded in the end groove 71, and the thread of the internal nut 7 is tightened inward to drive the retaining ring 6 to fit closely on the spherical surface of the ball valve core 5.

[0036] Moreover, a limiting outer shoulder 72 and a limiting inner shoulder 17 are respectively provided between the outer surface of the internal nut 7 and the inner surface of the inlet end 11, and the limiting outer shoulder 72 and the limiting inner shoulder 17 constitute the inward tightening stroke of the thread of the internal nut 7, thereby ensuring that the compression amount of the retaining ring 6 is in a suitable state, ensuring the sealing performance and extending the service life.

[0037] When the faucet of the utility model is turned on, since the flow path from the inlet end 11 to the water through hole 51 is a straight-through type, there is little obstruction when the fluid flows through the water through hole 51, and the flow rate changes very little, so the flow rate can be kept stable. Moreover, since the straight-through hole can have a larger diameter, its flow rate is also relatively large, which brings great convenience to high-rise users in water use.

[0038] Moreover, the water hole 51 is connected to the outlet end 12 via the tapered hole 14 and the inner hole 15 in sequence. In the process of water flowing in from the large hole and shrinking rapidly to flow out from the small hole, the water pressure is also increased in conjunction with the increase in the water flow rate. Therefore, it has good adaptability to the use environment with lower water pressure.

[0039] The above description is only a specific embodiment of the present invention. Those skilled in the art should understand that any structural design equivalent to this embodiment should be included in the protection scope of the present invention.
