Description

Technical Field

[0001] The utility model relates to the technical field of valves, in particular to an angle valve. Background Art

[0002] Angle valve is an angle stop valve. Angle valve is similar to ball valve, and its structure and characteristics are modified from ball valve. The difference from ball valve is that the outlet and inlet of angle valve form a right angle of 90 degrees.

[0003] The valve body of an existing angle valve is usually composed of an upper valve body, a middle valve body and a lower valve body. During installation, the upper valve body needs to be placed on the corresponding position of the middle valve body and welded, and then the valve stem and the ball are inserted, and then the lower valve body is placed in the corresponding position and welded again. Both ends need to be welded, and the welding quality must be guaranteed, otherwise leakage may occur from the welding position, which makes installation very troublesome. Utility Model Content

[0004] In summary, in order to overcome the deficiencies of the prior art, the utility model provides an angle valve that is easy to install.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an angle valve, comprising a main valve body, a lower valve body, a valve stem and a ball, the main valve body is provided with an inner cavity, the ball is located in the inner cavity, the ball is provided with a steering flow channel, the lower valve body is connected to the main valve body and connected to the inner cavity, the valve stem and the ball are linked, the side wall of the main valve body is provided with a side flow channel opening, and the main valve body is provided with an upper valve body which is integrally arranged therewith and connected to the inner cavity.

[0006] With this arrangement, the upper valve body will be integrated with the main valve body. Only the valve stem, the ball and the lower valve body need to be installed and welded. There is no need to weld the upper valve body, and leakage will not occur at the position of the upper valve body. The lower valve body can be welded in various lengths and styles according to the different needs of users, making installation more convenient.

[0007] Furthermore, the upper valve body is provided with a mounting hole adapted to the valve stem.

[0008] With this arrangement, the valve stem will pass through the upper valve body which is integral with the main valve body and be connected to the main valve body. Various notches will be provided in the mounting hole to adapt to the valve stem installation or to limit the rotation angle. Since the upper valve body is integrally provided, the connection strength is high, and the influence of the valve stem movement on the upper valve body is small, and the upper valve body will not loosen, fall off, or leak.

[0009] Furthermore, a thickened area is provided at the bottom of the upper valve body, and the outer diameter of the thickened area is greater than the outer diameter of the top of the upper valve body.

[0010] With such a setting, the setting of the thickened area further strengthens the strength of the connection position between the upper valve body and the main valve body, and at the same time, it is more convenient to set various notches, which can avoid the occurrence of the connection position being broken due to stress.

[0011] Furthermore, a connection hole communicating with the inner cavity is provided at the connection position between the main valve body and the lower valve body, and the diameter of the connection hole is larger than the diameter of the valve stem.

[0012] With such a setting, after the lower valve body is welded to the main valve body, the valve stem can also be passed through the connection hole and then inserted into the installation hole of the upper valve body, making the installation more convenient.

[0013] Furthermore, a connection groove adapted to it is provided at the connection position between the main valve body and the lower valve body.

[0014] With such a setting, the connection groove can play a positioning role when welding the lower valve body, and at the same time, it can increase the stability of the lower valve body after welding.

[0015] Furthermore, the diameter of the side flow port is larger than the outer diameter of the sphere, and the main valve body is provided with a side valve body detachably connected to the side flow port.

[0016] With such a setting, the sphere can be placed from the position of the side flow port, and after the sphere is placed, the side valve body can be installed, making the installation more convenient.

[0017] Furthermore, the side valve body and the side flow port are threadedly connected.

[0018] With such a setting, the side valve body can be installed only by rotation through threaded connection, the installation is convenient, and a sealing ring can be provided at the connection to prevent leakage. Description of the Drawings
