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

As shown in fig. 3, the water stop assembly 1 includes a spool outer tube 101, a cylindrical spool inner member 102, and an elastic member 103, and the elastic member 103 is preferably a spring.

As shown in fig. 4, the outer tube 101 of the valve core is substantially cylindrical, and a water flow passage is formed in the outer tube, and a water through port 1011 is formed in the water flow passage. The trim 102 and the elastic member 103 are disposed in the water flow passage. The trim 102 is configured to move with the wall of the flow passage. One end of the elastic member 103 abuts against the inner wall of the spool outer tube 101, and the other end abuts against the spool inner 102. When the outer valve assembly 2 is not engaged, the elastic member 103 applies elastic force to the trim 102 to make the trim 102 close the water through hole 1011, and the pressure of the same-direction water flow on the trim 102 is added, so that automatic water blocking can be realized. 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.

As shown in fig. 3 and 6, the outer wall surface of the outer valve element tube 101 is provided with a plurality of protrusions 1012, such as four protrusions in an equidistant ring shape.

As shown in fig. 3, the outer valve assembly 2 includes a valve housing 201. The valve housing 201 has a water inlet 2011, which is hollow and tubular.

As shown in fig. 5, the inner wall surface at the outer end edge of the water inlet end 2011 of the valve housing 201 is provided with a plurality of runners 2012 corresponding to the plurality of protrusions 1012, and a plurality of notches 2013 which are offset by a certain angle with respect to the plurality of runners 2012 as a whole. The water inlet end 2011 of the valve casing 201 is abutted with the valve element outer pipe 101, the sliding grooves 2012 are aligned with the protruding blocks 1012, the valve casing 201 is continuously pushed to the sliding grooves 2012 to completely slide over the protruding blocks 1012, the clamping grooves 2013 can be correspondingly fastened by rotating the valve casing 201, so that the valve casing 201 and the valve element outer pipe 101 are quickly jointed, after the jointing, the valve casing 201 pushes the valve element inner part 102 to compress the elastic part 103, the valve element inner part 102 opens the water through opening 1011, water flow is conducted, and water outlet is achieved.

As shown in fig. 3 and 7, the outer valve assembly 2 further includes a leakage-proof seal ring 202, and the leakage-proof seal ring 202 is embedded in the inner wall of the valve housing 201. When the valve housing 201 and the valve core outer pipe 101 are joined, the leak-proof seal ring 202 is in seamless contact with the outer wall of the valve core outer pipe 101, and water is prevented from leaking out from the joint gap between the valve housing 201 and the valve core outer pipe 101.

The direct-insertion rotary type quick-connection angle valve is designed with 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.

As shown in fig. 5, in order to achieve the joining of the two components more accurately, an annular advance-blocking ring 2014 is further provided on the inner wall surface of the water inlet end 2011 of the valve housing 201 inward relative to the chute 2012. The distance from the stopping ring 2014 to the sliding groove 2012 is slightly larger than the length (the axial dimension along the valve core outer tube 101) of the convex block 1012. The same side of all the slots 2013 is provided with a rotation-stopping block 2015 that stops the protrusions 1012 from rotating out of the side. The water inlet end 2011 of the valve casing 201 is butted with the valve core outer pipe 101, the sliding grooves 2012 are aligned with the protruding blocks 1012, and the valve casing 201 is directly inserted until the sliding grooves 2012 completely slide over the protruding blocks 1012 and are blocked by the blocking ring 2014. Due to the action of the rotation stopping block 2015, the valve housing 201 can only be rotated in one direction, if the valve housing 201 and the valve core outer tube 101 are designed to be rotated 55 degrees, the plurality of clamping grooves 2013 can be correspondingly fastened with the plurality of protruding blocks 1012, so that the valve housing 201 and the valve core inner tube 102 are jointed and fixed, and after the jointing, the valve housing 201 pushes the valve core inner tube 102 to conduct the water through opening 1011. In some embodiments, the rotation block 2015 may also be shorter to function as a fixation boss 1012. When the two components are detached, the valve casing 201 can be rotated towards the direction only by pulling the valve casing 201 out for a short distance.

As shown in fig. 6, two connected first and second cavities 1013 and 1014 are disposed inside the outer valve core tube 101, where the first and second cavities 1013 and 1014 are cylindrical cavities, and the two connected cavities form the water flow channel. In other embodiments, the first and second cavities 1013 and 1014 may also be designed in a prismatic shape or the like. 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 1011.

As shown in fig. 4, the valve trim 102 has a water seal plate 1021 and a guide 1022 that is movable along the second chamber 1014. The guiding element 1022 is fixedly connected to an end surface of the water sealing plate 1021. The water sealing plate 1021 can completely cover the water through port 1011. The guide 1022 has an open water passage. When the water stopping assembly 1 is separated from the outer valve assembly 2, the elastic member 103 pushes the water sealing plate 1021, so that the water sealing plate completely covers the water through port 1011. When the water stop assembly 1 is engaged with the outer valve assembly 2, the inner wall of the valve housing 201 pushes the guide 1022, the elastic member 103 is compressed, the water sealing plate 1021 is separated from the water through port 1011, the guide 1022 partially enters the first cavity 1013, and water in the first cavity 1013 can flow into the second cavity 1014 through the water through channel or directly flow out of the outer valve core 101.

As shown in fig. 8 and 9, the guiding member 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 guide 1022 is in the shape of the hollow cylinder 1028, the water holes 1029 formed in the hollow cylinder 1028 are configured such that the water holes 1029 can move into the first chamber 1013 after the inner wall of the valve housing 201 pushes the guide 1022. The water holes 1029 may 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 configuration of guides 1022 each form an open channel to allow for the passage of water from the first chamber 1013 to the second chamber 1014 when the strip 1022 is in both the first chamber 1013 and the second chamber 1014. The structure of the guide part 1022 enables the guide part to 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 hole 1011 due to large shaking and deviation is avoided, the water sealing plate 1021 can repeatedly seal the water through hole 1011, and stable and repeated water stopping is realized.

For example, as shown in fig. 3, 4 and 7, the guiding element 1022 is a hollow cylinder 1028, and two opposing water holes 1029 are disposed 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 elastic member 103 is compressed, so that the water sealing plate 1021 leaves the connecting step of the two cavities, and simultaneously the water hole 1029 of the hollow cylinder 1028 moves into the first cavity 1013 to communicate the water flow passage from the first cavity 1013 to the second cavity 1014.

As shown in fig. 3 and 4, 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 elastic member 103 is a spring, and two ends of the elastic member respectively abut against the clamp spring and the water sealing plate 1021. The clamp spring, the 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 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 seamlessly, and the water passing port 1011 is covered by the water sealing plate 1021 and the sealing member 104 seamlessly. When the water stop assembly 1 and the outer valve assembly 2 are engaged, the valve housing 201 pushes one end of the guide part 1022 far away from the water sealing plate 1021, so that the elastic part 103 is compressed, the water sealing plate 1021 and the sealing part 104 are separated from the water through port 1011, and the water flow passage from the first cavity 1013 to the second cavity 1014 is conducted.

Wherein an inclined surface 1015 is provided on the port of the second cavity 1014 at the step, as shown in fig. 6. When the water stop assembly 1 is separated from the outer valve assembly 2, the elastic member 103 pushes the water sealing plate 1021 and the sealing member 104 to be seamlessly attached to the inclined surface 1015 of the step. The angled surface 1015 engages the seal 104 more tightly and more securely than a horizontal surface.

When the water stop assembly 1 and the outer valve assembly 2 are separated, one end of the inner spool piece 102 away from the elastic member 103 extends out of the outer spool tube 101 (referring to fig. 7, the elastic member 103 is compressed, and one end of the inner spool piece 102 away from the elastic member 103 is pushed into the outer spool tube 101).

As shown in fig. 10, the inner wall of the water inlet 2011 of the valve housing 201 is provided with a blocking surface 2016, and the blocking surface 2016 may be an inner expanding circular ring surface as shown in fig. 10, so as to reduce the diameter, but the middle opening may be designed into other shapes, such as a semicircular surface. The blocking surface 2016 pushes against the protruding end of the inner cartridge 102 when the water shut-off assembly 1 and the outer valve assembly 2 are engaged, so that the protruding end is flush with the outer end of the outer cartridge tube 101 adjacent to the second chamber 1014 (as shown in fig. 7), and the water sealing plate 1021 and the sealing member 104 are disengaged from the water through port 1011 (see fig. 7), thereby opening the water flow path.

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 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 2016 of the water inlet end 2011 of the valve housing 201 is configured to also extend into the outer valve core member 101 and push against the end of the inner valve core member 102 away from the elastic member 103, so that the water sealing plate 1021 and the sealing member 104 are simultaneously disengaged from the water through port 1011.

As shown in fig. 3 and 7, the water stopping assembly 1 may further include a positioning ring cover 106 disposed on the periphery of the outer valve element pipe 101, so that when the water stopping assembly 1 and the outer valve assembly 2 are joined, the front end of the water inlet end 2011 of the valve housing 201 abuts against the positioning ring cover 106, which assists in achieving precise positioning joining of the water stopping assembly 1 and the outer valve assembly 2.
