Description

Technical field:

[0001] The utility model relates to the technical field of hardware, in particular to a universal connection angle valve. Background technology:

[0002] Angle stop valve is also called angle valve for short. Its outlet and inlet form a right angle structure of approximately 90 degrees. Angle valve is often used in water and electricity installation in the decoration industry and is an important plumbing accessory.

[0003] At present, when connecting an external hose to a pipe pre-buried in the wall, an angle valve is often used for conversion. Since most existing angle valves are integrated structures, when the angle valve is installed on the pre-buried pipe in the wall, the water outlet of the angle valve can only face one direction and is not easy to adjust. After the angle valve is installed on the pre-buried pipe, the water outlet is fixed and cannot be adjusted after installation. There is a situation where the threaded connection position with the hose is incorrect, making the connection inconvenient, especially for pipes laid in the corners of the wall, where ordinary angle valves cannot be installed due to the fixed water outlet. In addition, when the water outlet direction of the angle valve does not match or is opposite to the installation angle of the external hose, the external hose is also prone to bending after installation, affecting the water output and shortening the service life of the hose. Utility model content:

[0004] The technical problem to be solved by the utility model is to provide a universal connection angle valve, which has a simple structure and is quick and convenient to install, and can effectively solve the shortcomings of the prior art that the water outlet is fixed, the water outlet cannot be adjusted after installation, and the pipes in the corners of the wall cannot be installed.

[0005] The technical solution of the utility model is to provide a universal connection angle valve, including:

[0006] The angle valve body comprises a tubular shell body and a water inlet section and a water flow section respectively arranged at both ends of the shell body and connected to the shell body, wherein the water flow section comprises a first sealing connection part, a water flow part and a second sealing connection part in sequence along the axial direction, the first sealing connection part is located between the shell body and the water flow part, the water flow part comprises an annular groove, and a plurality of water flow holes are opened on the annular groove;

[0007] A ceramic valve core is installed in the water flow section, the head end face of the ceramic valve core abuts against the inner wall of the first sealing connection part, and a sealing connection is formed by a sealing gasket on the head end face of the ceramic valve core abutting against the inner wall of the first sealing connection part, the tail end peripheral surface of the ceramic valve core is threadedly connected with the inner wall of the second sealing connection part, and a gap is set between the inner wall of the annular groove and the ceramic valve core;

[0008] The universal shell includes a tubular tube shell and a water outlet section arranged radially along the tube shell. The water outlet section is connected to the tube shell. The tube shell is sleeved on the outer wall of the water passing section and is rotatably connected to the water passing section. The position of the water outlet section corresponds to the position of the water passing part.

[0009] Through the above structure, water in the external water inlet pipe enters the water inlet section, flows through the first sealing connection of the water section and then enters the ceramic valve core. When the ceramic valve core is opened, the water in the ceramic valve core can enter the water passing part through the water outlet hole on the ceramic valve core and flow out from its water outlet hole, then enter the tube housing, and flow out from the water outlet section connected to the tube housing. Preferably, the water outlet hole on the peripheral surface of the ceramic valve core near the middle position is coaxial with the inner cavity of the water outlet section of the universal housing, and the central axis of the two is located in the middle position of the annular groove, so that the water flow is more sufficient.

[0010] Preferably, the outer circumferences of the first sealing connection part and the second sealing connection part are provided with sealing grooves along the circumferential direction, and a sealing ring is embedded in the sealing groove. The sealing ring is tightly matched with the inner wall of the tube housing to form a sealing structure to prevent water from overflowing from the tube housing and the first sealing connection part or between the tube housing and the second sealing connection part. Preferably, the outer circumferential surfaces of the first sealing connection part and the second sealing connection part are respectively provided with two sealing grooves along the axial direction, and the adjacent sealing grooves are arranged at intervals, that is, four sealing rings are arranged between the tube housing and the first sealing connection part and the second sealing connection part to form double sealing protection to achieve a better sealing effect.

[0011] Preferably, the water outlet section is arranged in the middle of the tube housing, and the inner walls at both ends of the tube housing are respectively provided with positioning sinks, and correspondingly, the outer peripheral surfaces of the first sealing connection part and the second sealing connection part are provided with positioning grooves along the circumferential direction, and positioning collars are embedded in the positioning grooves, and the positioning collars and the positioning sinks are engaged with each other to realize the positioning of the tube housing and the first sealing connection part and the second sealing connection part. Preferably, the peripheral wall of the positioning collar is provided with an installation gap (non-closed annular structure) along the axial direction, so that the positioning collar can be sleeved in the positioning groove.

[0012] Preferably, a groove is provided on the inner wall of the middle position of the tube housing opposite to the water outlet section. That is to say, taking the water outlet section being located above the tube housing as an example, the groove is provided below the inner wall of the tube housing opposite to the water outlet section. The groove design ensures that the water flow is sufficient when the universal housing is rotated to different angles.

[0013] Preferably, the cross section of the cavity of the water outlet section close to one end of the tube shell is in the shape of a waist-shaped hole, and the design of the waist-shaped hole can better ensure the flow of water.

[0014] Preferably, a positioning nut is further included, which is screwed on the rear end peripheral surface of the ceramic valve core and abuts against the outer end surface of the second sealing connection portion. The universal housing can be further restricted on the angle valve body without axial movement by the positioning nut.

[0015] As a preference, a hand wheel is further included, the hand wheel is sleeved on the tail end of the ceramic valve core and connected to the rotating shaft extending from the tail end of the ceramic valve core by a screw. Preferably, the outer diameter of the hand wheel is consistent with the outer diameter of the tube housing.

[0016] Preferably, a decorative cover is further included, which is sleeved on the water inlet section and is used for connecting the angle valve and the wall where the external water inlet pipe is located.

[0017] The universal housing can rotate arbitrarily in the circumferential direction relative to the angle valve body. The cooperation of the positioning clamp ring, the sealing ring and the positioning nut limits the axial movement of the universal valve body relative to the angle valve body. The ceramic valve core is used to adjust the size of the water flow and control the switch of the water flow. The ceramic valve core can select the valve core of the existing structure.

[0018] During installation, the ceramic valve core is installed in the inner cavity of the angle valve body and is located in the water flow section. The ceramic valve core is used to open or close the water path from the water inlet section to the water flow section. The universal housing is sleeved on the water flow section and tightly matches the first sealing connection part and the second sealing connection part at both ends of the water flow section and can rotate 360° circumferentially relative to the water flow section. The hand wheel is sleeved on the outer surface of the ceramic valve core and is connected to the rotating shaft extending from the tail end of the ceramic valve core through a screw. The operator controls the opening or closing of the ceramic valve core by rotating the hand wheel.

[0019] The decorative cover is sleeved on the water inlet section, and the decorative cover is used to cooperate with the wall to cover the water outlet pipe embedded in the wall. During installation, the water inlet section needs to pass through the decorative cover and be threadedly connected with the water outlet pipe embedded in the wall.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

Specific implementation method:

[0032] The present invention will be further described below with reference to the accompanying drawings:

[0033] Angle valve is also called angle stop valve. Angle valve has similar functions to ball valve, both of which are used to transfer water pipes. The difference between angle valve and ball valve is that the outlet and inlet of angle valve are roughly at a right angle of 90 degrees. Angle valve is mostly used for water and electricity installation in the decoration industry and is an important plumbing accessory.

[0034] Angle valves have the following functions: 1. Switching between internal and external water outlets; 2. Adjusting water pressure; 3. Controlling water flow switches, etc. At present, angle valves are often used for switching when connecting external hoses to pipes pre-buried in the wall.

[0035] Since most angle valves are integrated structures, during installation, the angle valve rotates as a whole relative to the outlet pipe pre-buried in the wall. After installation, the outlet end of the angle valve can only face one position, and the direction of the outlet end cannot be adjusted. When installing an external hose on the outlet end of the angle valve, when the outlet end direction does not match the installation angle of the external hose, it will make the installation of the external hose difficult, and the external hose after installation is easy to bend and twist, which not only affects the water outlet effect, but also accelerates the aging or damage of the external hose to a certain extent, and even shortens the service life of the external hose. Even some pipes laid in the corners of the wall cannot be installed with ordinary angle valves because the outlet is fixed.

[0036] like Figure 1-9 As shown, a universal connection angle valve mainly includes an angle valve body 2, a universal housing 5 and a ceramic valve core 6. Among them,

[0037] The angle valve body 2 includes a tubular shell body 21 and a water inlet section 22 and a water flow section 23 respectively arranged at both ends of the shell body 21 and connected to the shell body, wherein the water flow section 23 includes a first sealing connection part 231, a water flow section and a second sealing connection part 232 in the axial direction, the first sealing connection part 231 is located between the shell body 21 and the water flow section, the water flow section includes an annular groove 233, and four water flow holes 234 are evenly distributed on the circumference of the annular groove 233; in this embodiment, the water inlet section 22, the shell body 21 and the water flow section 23 are integrally formed. The water inlet section 22 is used as the water inlet end of the angle valve and is used for fixed connection with the outlet pipe pre-buried in the wall.

[0038] The ceramic valve core 6 is installed in the water passing section 23, the head end face of the ceramic valve core 6 abuts against the inner wall of the first sealing connection part 231, and a sealing fit is formed by the sealing gasket of the head end face of the ceramic valve core 6 abutting against the inner wall of the first sealing connection part 231, the tail end peripheral surface of the ceramic valve core 6 is threadedly connected to the inner wall of the second sealing connection part 232, and a gap is set between the inner wall of the annular groove and the ceramic valve core 6, so that water can flow out from the water passing hole 234. It should be understood that the ceramic valve core 6 can adopt the structure of the existing technology.

[0039] The universal housing 5 includes a tubular tube housing 51 and a water outlet section 52 arranged along the radial direction of the tube housing. The water outlet section 52 is connected to the tube housing 51. The tube housing 51 is sleeved on the outer wall of the water passing section 23 and is rotatably connected to the water passing section 23. The position of the water outlet section 52 corresponds to the position of the water passing section. Here, the position of the water outlet section 52 corresponds to the position of the water passing section, which means that the water outlet section 52 is connected to the water passing hole 234 of the water passing section. The water outlet section 52 serves as the water outlet end of the angle valve. Like the existing angle valve, the water inlet section and the water outlet section of the utility model are arranged at an angle of approximately 90°.

[0040] Through the above structure, water in the external water inlet pipe enters the water inlet section 22, and flows through the first sealing connection part 231 of the shell body 21 and the water flow section 23 before entering the ceramic valve core 6. When the ceramic valve core 6 is opened, the water in the ceramic valve core 6 can enter the water flow section through the water outlet hole 61 on the ceramic valve core 6 and flow out from its water flow hole 234, and then enter the tube shell 51, and flow out from the water outlet section 52 connected to the tube shell 51. Preferably, the water outlet hole 61 on the circumferential surface of the ceramic valve core 6 near the middle position is coaxial with the inner cavity of the water outlet section 52 of the universal shell 5, and the central axis of the two is located in the middle position of the annular groove, so that the water flow is more sufficient. After installation, the universal shell can be rotated arbitrarily along the circumferential direction relative to the angle valve body to adjust the direction of the water outlet end of the angle valve to meet the directional installation requirements of the external water pipe, so as to ensure that the external water pipe after installation can extend naturally without bending or twisting.

[0041] like Figure 2-4 As shown, in this embodiment, the shell body 21 and the tube shell 51 are both hollow columnar structures, and for easy installation, a wrench flat is provided on the circumference of the shell body 21. The tube shell 51 and the water outlet section 52 arranged radially along the tube shell are also integrally formed.

[0042] As an implementation method, Figure 2 , 8 As shown, the outer circumferential surfaces of the first sealing connection part 231 and the second sealing connection part 232 of the angle valve body 2 are respectively provided with two sealing grooves spaced apart in the circumferential direction, and the sealing grooves are embedded with sealing rings 4, which are tightly matched with the inner wall of the tube housing 51 to form a sealing structure to prevent water from overflowing from the tube housing 51 and the first sealing connection part 231 or between the tube housing 51 and the second sealing connection part 232. In other words, four sealing rings 4 are arranged between the tube housing 51 and the first sealing connection part 231 and the second sealing connection part 232, respectively forming double sealing protection to achieve a better sealing effect.

[0043] As an implementation method, Figure 4 , 5As shown, the water outlet section 52 is arranged in the middle of the tube housing 51, and the inner walls at both ends of the tube housing 51 are respectively provided with positioning sinks 511. Correspondingly, the outer peripheral surfaces of the first sealing connection part 231 and the second sealing connection part 232 are provided with positioning grooves along the circumferential direction, and the positioning collar 3 is embedded in the positioning groove. The positioning collar 3 and the positioning sink 511 are engaged and matched to realize the positioning of the tube housing 51 and the first sealing connection part 231 and the second sealing connection part 232. Preferably, the peripheral wall of the positioning collar 3 is provided with an installation gap 31 along the axial direction, so that the positioning collar 3 is evolved from a closed annular structure to an open structure, and the positioning collar 3 has a certain elasticity. During installation, the positioning collar 3 can be opened under the action of external force, which is conducive to conveniently setting the positioning collar 3 in the positioning groove. And after the external force is removed, the positioning collar 3 is reset to clamp the positioning groove and cooperate with the positioning sink 511 of the tube housing 51 to limit the position.

[0044] As an implementation method, Figure 5 As shown, a groove 512 is further provided on the inner wall of one side of the middle position of the tube housing 51 opposite to the water outlet section. Taking the water outlet section shown in the figure as an example, the groove 512 is provided below the inner wall of the tube housing 51 and opposite to the water outlet section 52. The design of the groove 512 can ensure that the water flow is sufficient when the universal housing 5 is rotated to different angles.

[0045] In this embodiment, Figure 6 As shown, the cross section of the cavity of the water outlet section 52 close to one end of the tube housing 51 is in the shape of a waist-shaped hole, and the waist-shaped hole design can better ensure the flow of water.

[0046] As another embodiment, the utility model further includes a positioning nut 7, which is screwed on the rear end circumference of the ceramic valve core 6 and abuts against the outer end surface of the second sealing connection portion 232. Through the positioning nut 7, the universal housing 5 can be further restricted on the angle valve body 1 without axial movement. The cooperation of the positioning collar 3, the sealing ring and the positioning nut 7 restricts the axial movement of the universal housing 5 relative to the angle valve body 2.

[0047] Preferably, a hand wheel 8 is further included, which is sleeved on the tail end of the ceramic valve core 6 and connected to the rotating shaft extending from the tail end of the ceramic valve core 6 through a screw 9, and the screw 9 is shielded and beautified by a rubber plug 10. In this embodiment, the outer diameter of the hand wheel 8 is consistent with the outer diameter of the tube housing 51.

[0048] To facilitate installation, wrench flats are also provided on the circumferential surfaces of the hand wheel 8 and the positioning nut 7.

[0049] Like the existing angle valve, the utility model also includes a decorative cover 1, which is sleeved on the water inlet section 22 and is used to connect the angle valve and the wall where the external water inlet pipe is located. The decorative cover 1 is a structure of the prior art.

[0050] When the external hose is connected to the outlet pipe embedded in the wall through a universal angle valve, the position and angle of the external hose can be adjusted. Fig. 9 As shown, adjust the direction of the outlet section of the universal housing. At this time, the universal housing can be rotated arbitrarily along the circumferential direction relative to the angle valve body to match the direction of the outlet section with the installation angle of the external hose. Finally, the external hose is fixedly connected to the outlet section of the universal housing. In addition, it can overcome the problem that ordinary angle valves cannot be installed due to the fixed outlet of the pipes laid in the corners of the wall.

[0051] The above is only an explanation of the preferred embodiments of the utility model, which cannot be understood as a limitation of the claims. Any equivalent structure or equivalent process changes made using the utility model specification are included in the patent protection scope of the utility model.
