DETAILED DESCRIPTION

[0029] In order to further explain the technical scheme of the utility model, the utility model will be described in detail through specific embodiments.

[0030] As Figures 1 to 3 Indicated, it is a kind of angle-adjustable explosion-proof valve of facilitating that the utility model relates to, can be installed in water supply pipeline interface 100, including shell 1 and the explosion-proof assembly 3 in shell 1, the shell 1 outer wall has outer thread section 11, the shell 1 has water outlet 13 and sealing gasket 2 fixedly installed in the outer periphery of water outlet 13, the thickness L of sealing gasket 2 is 2.5-7mm.

[0031] In this way, with the installation of angle valve 200 or faucet into water supply pipeline interface 100, the pipe joint 210 of angle valve 200 or faucet is abutted on sealing gasket 2, the thickness of sealing gasket 2 is set to 2.5-7mm, so that pipe joint 210 still has certain compressibility when guaranteeing sealing, still has 360 degrees adjustable space, so that angle valve or faucet is towards predetermined position.

[0032] Preferably, the thickness L of the sealing gasket 2 is 4-6mm; the external thread on the external thread section 11 is 4-pitch thread or 6-pitch thread; the axial compressible amount of the sealing gasket 2 is greater than 1.5 times the pitch of the external thread section 11. During the self-contact sealing of the pipe joint, the sealing gasket 2 needs to be axially compressed for a distance to generate enough compression force to realize sealing; the axial compressible amount of the sealing gasket 2 is greater than 1.5 times the pitch of the external thread section 11, and still has an adjustable compression amount of more than 1 times the pitch after removing the initial compression state part distance, thus ensuring the angle adjustment of the angle valve or faucet. Taking the 4-pitch pipe thread as an example, the thickness of the sealing gasket 2 is 5mm, and after the sealing gasket 2 is compressed to be water-tight, it still has an adjustable compression amount of more than 1 times the pitch. Preferably, the sealing gasket 2 is made of rubber material. The rubber material has the advantage of wear resistance, which is beneficial to improve the service life of the sealing gasket 2.

[0033] Preferably, one end of the external thread section 11 is formed with a sealing end face 12, the external thread on the external thread section 11 extends to the edge of the sealing end face 12, and the sealing gasket 2 is attached to the sealing end face 12. The extension of the external thread on the external thread section 11 to the sealing end face 12 makes the external thread section 11 and the sealing gasket 2 more compact in the axial direction, reduces the occupation of the internal thread in the water supply pipe interface 100, and makes the pipe joint of the angle valve or faucet more firmly connected with the water supply pipe interface 100.

[0034] Preferably, the diameter of the sealing gasket 2 is smaller than the small diameter of the external thread on the external thread section 11. In this way, the diameter of the sealing gasket 2 is also smaller than the small diameter of the internal thread in the water supply pipe interface 100, making the installation of the explosion-proof valve more smooth and reducing the resistance.

[0035] Preferably, an annular convex edge 14 and an annular groove 15 are formed on the outer shell of the outer periphery of the water outlet 13, the axial ends of the annular groove 15 are limited by the annular convex edge 14 and the sealing end face 12, and the sealing gasket 2 is installed in a sleeve joint on the outer periphery of the annular convex edge 14 and the annular groove 15. The sealing gasket 2 is limited by the annular groove 15 to avoid falling out.

[0036] Further, the rotational cross section of the sealing gasket 2 is convex, the inner side of the sealing gasket 2 is formed with a limiting convex edge 21, the two sides of the limiting convex edge 21 are respectively provided with an annular mounting groove 22 and an annular avoidance groove 23, the annular convex edge 14 is embedded into the annular mounting groove 22, and the limiting convex edge 21 is located in the annular groove 15. The annular avoidance groove 23 reduces the cross-sectional area of the sealing gasket 2 at the position, so that the axial compression amount of the sealing gasket 2 increases under the same pressure, which is beneficial to still have a certain compression amount for adjusting the angle of the angle valve or faucet during sealing.

[0037] Preferably, the water outlet 13 has a spanner hole. The spanner hole is used to connect a spanner, facilitating the connection of the outer threaded section 11 on the shell 1 with the water supply pipeline interface 100.

[0038] Preferably, the shell 1 is provided with a mounting cavity 16; the explosion-proof assembly 3 comprises a movable core 31 and a spring 32 sleeved outside the movable core 31, the spring 32 abuts against the movable core 31 from the water outlet 13 direction to the water inlet direction, and the movable core 31 can move back and forth in the mounting cavity 16 to block or open the water outlet 13 with the change of water pressure.

[0039] Compared with the prior art, the thickness of the sealing gasket 2 is adjusted to 2.5-7 mm, so that after sealing, the faucet and the angle valve still have an angle adjusting space of 1 / 4, the faucet and the angle valve are directed to a predetermined direction, and the butt joint with the pipeline is facilitated.
