Detailed Description

The following provides a detailed description of some embodiments of the in-line quick connect angle valve of the present invention with reference to the accompanying drawings.

As shown in fig. 1 and 2, the direct-insertion type quick-connection angle valve comprises a water stop assembly 1 and an outer valve assembly 2 which can be mutually detached or jointed.

As shown in fig. 3, the outer valve assembly 2 includes a valve housing 201, an annular sliding sleeve 202, a second resilient member 203, and eight beads 204. In this embodiment, the sliding sleeve 202 is a hollow cylinder, and in other embodiments, it may also be a hollow prism. The ball 204 may be a spherical steel ball. The valve housing 201 has a water inlet 2011, which is round and tubular.

As shown in fig. 4, the outer wall surface of the water inlet end 2011 has a first stop surface 2012 and a second stop surface 2013 circumferentially arranged along the water inlet end 2011, eight ball holes 2014 penetrating through the valve casing wall are arranged between the first stop surface 2012 and the second stop surface 2013, and the ball holes 2014 may be equidistantly arranged around the water inlet end 2011 of the valve casing 201 to form a circle of balls 204. In the present embodiment, the ball hole 2014 is a circular hole, but is not limited thereto, and may be shaped to perform the following functions. Each ball 204 can fit into one of the ball holes 2014, and the ball 204 can be exposed at the bottom and top of the ball hole 2014. The diameter of the ball hole 2014 close to the inner wall surface is smaller than that of the ball 204, for example, a necking ring may be provided on the ball hole 2014 close to the inner wall surface (i.e., the bottom of the ball hole 2014), which is designed such that the ball 204 does not fall out of the ball hole 2014 inward when the outer valve assembly 2 is detached from the water stop assembly 1.

Referring to fig. 3 to 5, the second elastic member 203 is disposed between the first shift surface 2012 and the second shift surface 2013 and abuts against the first shift surface 2012, or one end of the second elastic member 203 is welded on the first shift surface 2012.

The second elastic member 203 may be any elastic member capable of being compressed and playing a role of rebounding, for example, a plurality of strip-shaped elastic members are axially installed on the outer wall surface of the water inlet end 2011. The sliding sleeve 202 is sleeved outside the water inlet end 2011. In this embodiment, as shown in fig. 3 to 5, the second elastic member 203 is a spring, which is sleeved on the outer wall surface of the water inlet 2011 and can be completely wrapped by the sliding sleeve 202 without being separated from the first gear surface 2012.

As shown in fig. 6, the inner wall of the sliding sleeve 202 has an inwardly protruding inner collar 2021. The inner collar 2021 has an inward facing front ring surface 2022 and first and second side surfaces 2023 and 2024 on both sides. Referring to fig. 5 and 6, the front ring surface 2022 abuts against the ball 204, the first side surface 2023 abuts against an end of the second elastic member 203 away from the first shift surface 2012, and the second side surface 2024 may be an arc surface or an inclined surface. The sliding sleeve 202 further abuts against the second stop surface 2013, either the second side surface 2024 abuts against the second stop surface 2013 or the upper end of the sliding sleeve 202 abuts against the second stop surface 2013. The abutment can be close contact or a certain loosening range. After the sliding sleeve 202 is pulled to completely compress the second elastic member 203, the front ring surface 2022 of the inner ring 2021 is separated from the ball 204, so that the range of the moving diameter of the ball 204 can be increased.

As shown in fig. 6, in a preferred embodiment, the first side surface 2023 of the inner collar 2021 is an upright surface, and the second side surface 2024 is a concave arc surface. Referring to fig. 4 to fig. 6, the maximum distance from the second side 2024 to the outer wall surface of the water inlet 2011 of the valve housing 201 is smaller than the diameter of the ball 204. When the sliding sleeve 202 is not pulled, the second side 2024 abuts against the second stop surface 2013. When the sliding sleeve 202 is pulled to completely compress the second elastic member 203, the second side 2024 is stopped at the outer side of the ball 204, so that the ball 204 cannot fall out of the ball hole 2014, and after the sliding sleeve 202 is loosened, the second side 2024 smoothly presses the ball 204 to completely enter the ball hole 2014 until the positive ring surface 2022 of the inner ring 2021 abuts against the outer end of the ball 204, and at this time, the inner end of the ball 204 can be exposed out of the ball hole 2014 inwards, so as to facilitate the joint fixation of the water inlet end 2011 of the valve housing 201 and the water stop assembly 1.

As shown in fig. 3, 5 and 7, the water stopping assembly 1 includes a spool outer tube 101, a spool inner 102 and a first elastic member 103. The first resilient member 103 is preferably a spring.

As shown in fig. 8, the outer tube 101 of the valve core may be substantially cylindrical, and a circumferential bead groove 1011 is formed on an outer wall surface thereof. A water flow channel is arranged in the outer valve core pipe 101, and the middle part of the water flow channel is provided with a water through hole 1012. The valve core inner member 102 and the first elastic member 103 are both disposed in the water flow passage. When the outer valve component 2 is separated from the water stopping component 1, the first elastic member 103 can push the valve core inner member 102 to close the water through port 1012, and automatic water stopping can be realized by combining the pressure of water. The water stopping assembly 1 can be pre-buried in a wall, and one end of the outer valve core pipe 101 can be provided with an external thread for being connected with a water source end buried in the wall in a threaded mode.

In the installation process, the outer valve component 2 is directly inserted into the water stop component 1 for rapid fixation, the specific operation is that the sliding sleeve 202 is pulled backwards (in the direction of compressing the second elastic member 203), the movable ring diameter of the ball 204 is increased, the water inlet end 2011 of the valve shell 201 is continuously sleeved outside the valve core outer tube 101, the inner wall of the water inlet end 2011 can push the valve core inner part 102 inwards to open the water through port 1012, at the moment, the sliding sleeve 202 is loosened, the sliding sleeve 202 can completely press each ball 204 into the ball hole 2014, so that a part of the ball 204 can be exposed out of the bottom of the ball hole 2014 and sunk into the ball groove 1011, and the movable ring diameter of the ball 204 is contracted. Due to the limiting function of the sliding sleeve 202, the ball 204 cannot slide out of the ball groove 1011 at the moment, so that the water inlet end 2011 of the valve casing 201 and the valve core outer pipe 101 are fixed to each other, that is, the outer valve component 2 and the water stop component 1 are fixed to each other, and the functions of quick engagement and water passing are realized.

When the outer valve assembly 2 needs to be detached from the water stop assembly 1, after the sliding sleeve 202 is pulled to completely compress the second elastic member 203, the front ring surface 2022 of the inner ring 2021 is separated from the ball 204, the moving ring diameter of the ball 204 is increased, the outer valve assembly 2 is continuously pulled out, the ball 204 can smoothly slide out of the ball groove 1011, and the outer valve assembly 2 is separated from the water stop assembly 1.

The direct-insertion type quick-connection angle valve is designed into a mutual plugging structure of two subsections, and can automatically block water by the water stopping assembly 1 under the condition that the outer valve assembly 2 bursts. After the installation, outer valve unit spare 2 can also be relative stagnant water subassembly 1 and rotate with 360, satisfies the water demand of arbitrary angle.

As shown in fig. 8, the inside of the outer valve core tube 101 is provided with a first chamber 1013 and a second chamber 1014 connected in two sections, each of the first chamber 1013 and the second chamber 1014 may be a cylindrical chamber, and the two connected chambers form the water flow channel. The outer wall surface of the first chamber 1013 may be provided with external threads for connecting to a water source embedded in a wall. At the junction of the two chambers, the radial dimension of the first chamber 1013 is greater than the radial dimension of the second chamber 1014, forming a step, and the port of the second chamber 1014 at the junction is the water port 1012.

As shown in fig. 7, the valve trim 102 has a water trap 1021 and a rail 1022 that moves along the second chamber 1014. The strip 1022 is fixedly connected to the end surface of the water sealing plate 1021. The water sealing plate 1021 can completely cover the water passage port 1012. The bar 1022 has an open channel. When the water stopping assembly 1 is separated from the outer valve assembly 2, the first elastic member 103 pushes the water sealing plate 1021 to completely cover the water passage port 1012. When the water stop assembly 1 and the outer valve assembly 2 are engaged, the inner wall of the valve housing 201 pushes the strip 1022, the first elastic member 103 is compressed, the water sealing plate 1021 is separated from the water passage 1012, and the water flowing into the first cavity 1013 flows out of the valve core outer tube 101 through the water passage.

As shown in fig. 9 and 10, the strip 1022 may be a straight plate 1023, a three-blade plate 1024, a cross plate 1025, a five-blade plate 1026, a six-blade plate 1027, or a hollow cylinder 1028 with water holes 1029 on the cylinder wall, etc. When the bar 1022 is shaped as a hollow cylinder 1028, the hollow cylinder 1028 has water holes 1029 configured such that after the inner wall of the valve housing 201 pushes against the bar 1022, the water holes 1029 can move into the first cavity 1013, and can be generally disposed at the upper end of the hollow cylinder 1028 near the water sealing plate 1021. In the above structure of the straight plate 1023, the three-blade plate 1024, the cross plate 1025, the five-blade plate 1026 and the six-blade plate 1027, the gap between the straight plate 1023 and the first cavity 1013 and the second cavity 1014 of the outer valve core tube 101 form an open water channel, and similarly, for other multi-plate structures, the gap between every two blade plates forms an open water channel. For the hollow cylinder 1028 with water holes 1029 on the cylinder wall, an open water passage is formed by the inner cavity of the hollow cylinder 1028 and the communication channel of the water holes 1029. The above configurations of noodle 1022 each form an open channel to allow for the passage of water from first chamber 1013 to second chamber 1014 when noodle 1022 is in both first chamber 1013 and second chamber 1014. The strip 1022 can laterally abut against the wall of the second cavity 1014 and stably move along the axial direction of the second cavity 1014, so that the problem that the water sealing plate 1021 cannot completely cover the water through opening 1012 due to large shaking and deviation is avoided, the water sealing plate 1021 can repeatedly seal the water through opening 1012, and stable and repeated water stopping is realized.

For example, as shown in fig. 3, 5 and 7, the strip 1022 is a hollow cylinder 1028, and two opposite water holes 1029 are formed on the wall of the hollow cylinder 1028 adjacent to the water sealing plate 1021. The water sealing plate 1021 is a circular plate, the outer diameter of the water sealing plate is larger than that of the hollow cylinder 1028, and the outer diameter of the hollow cylinder 1028 is approximately equal to that of the second cavity 1014. When the water stop assembly 1 and the outer valve assembly 2 are engaged, the valve housing 201 pushes one end of the hollow cylinder 1028 away from the water sealing plate 1021, the first elastic member 103 is compressed, so that the water sealing plate 1021 is away from the connecting step of the two cavities, and simultaneously the water holes 1029 of the hollow cylinder 1028 move into the first cavity 1013, and the water flow passage from the first cavity 1013 to the second cavity 1014 is conducted.

As shown in fig. 3 and 5, the water stop assembly 1 further includes a sealing member 104 and a stopper 105. The sealing member 104 is a sealing O-ring, the limiting member 105 is a snap spring, and the snap spring is fixed in the first cavity 1013 of the outer valve element tube 101. The seal member 104 is fitted around the periphery of the water sealing plate 1021. The first elastic member 103 is a spring, and two ends of the first elastic member respectively abut against the clamp spring and the water sealing plate 1021. The clamp spring, the first elastic member 103 and the water sealing plate 1021 are all located in the first cavity 1013. When the water stopping assembly 1 is separated from the outer valve assembly 2, the first elastic member 103 pushes the valve core inner member 102 outwards, so that the sealing member 104 is attached to the step of the two sections of cavities in a seamless manner, and the water passing port 1012 is covered by the water sealing plate 1021 and the sealing member 104 in a seamless manner. When the water stop assembly 1 and the outer valve assembly 2 are engaged, the valve housing 201 pushes one end of the strip 1022 far away from the water sealing plate 1021, so that the first elastic member 103 is compressed, the water sealing plate 1021 and the sealing member 104 are separated from the water through port 1012, and a water flow passage from the first cavity 1013 to the second cavity 1014 is conducted.

Wherein, as shown in fig. 8, an inclined surface 1030 is provided on the port of the second cavity 1014 at the step. When the water stop assembly 1 is separated from the outer valve assembly 2, the first elastic member 103 pushes the water sealing plate 1021 and the sealing member 104 to be seamlessly attached to the inclined surface 1030 at the step. The angled surface 1030 engages the seal 104 more tightly and securely than the horizontal surface.

When the water stopping assembly 1 is separated from the outer valve assembly 2, one end of the inner valve element 102, which is far away from the first elastic member 103, extends out of the outer valve element tube 101 (referring to fig. 5, the first elastic member 103 is compressed, and one end of the inner valve element 102, which is far away from the first elastic member 103, is pushed into the outer valve element tube 101).

As shown in fig. 11, the inner wall of the water inlet end 2011 of the valve housing 201 is provided with a blocking surface 2015, the blocking surface 2015 can be set as an inner expanding circular ring surface as shown in fig. 11, so as to reduce the caliber, but the middle opening can be designed into other shapes, such as a semicircular surface. The blocking surface 2015 can push the protruding end of the inner plug member 102 to be flush with the outer end of the outer plug tube 101 adjacent to the second chamber 1014 (as shown in fig. 5) when the water-stop assembly 1 and the outer valve assembly 2 are engaged, and can separate the water-sealing plate 1021 and the sealing member 104 from the water through port 1012 (refer to fig. 5, 7 and 8) to open the water flow passage.

In other embodiments, when the water stop assembly 1 and the outer valve assembly 2 are separated, the end of the inner valve core member 102 away from the first elastic member 103 may not extend out of the outer valve core member 101, but when the water stop assembly 1 and the outer valve assembly 2 are engaged, the blocking surface 2015 of the water inlet end 2011 of the valve housing 201 is configured to extend into the outer valve core member 101 and push against the end of the inner valve core member 102 away from the first elastic member 103, so that the water sealing plate 1021 and the sealing member 104 are disengaged from the water through port 1012 at the same time.

The outer valve component 2 further includes a gear O-ring 205 that is annularly embedded on the outer wall surface of the water inlet end 2011 of the valve housing 201 and is higher than the outer wall surface to form the second retaining surface 2013, and the second side surface 2024 of the inner collar 2021 abuts against the gear O-ring 205.

As shown in fig. 11 and 5, the outer valve assembly 2 further includes a leak-proof sealing ring 206 embedded in the inner wall of the water inlet 2011 of the valve housing 201.
