Description

Technical Field

[0001] This utility model belongs to the field of lock valve technology, and specifically relates to a fully welded dustproof and anti-theft lock valve. Background Technology

[0002] The valve body of existing lock valves is mostly made of castings and is usually connected by threads. However, castings inevitably have some process defects, such as air holes, sand holes, cracks, etc., which will affect the quality of the product to a certain extent.

[0003] In addition, existing lock valves generally have anti-theft structures. The latest type of anti-theft lock valve is a magnetic anti-theft structure. For example, patent CN217301696U discloses a magnetic anti-theft lock valve. The upper end of the valve stem end cover (8) is provided with a magnetic anti-theft lock cover (14). The lower part of the magnetic anti-theft lock cover (14) is inserted into the valve stem end cover (8). A control cavity is opened in the magnetic anti-theft lock cover (14) and at the corresponding position inside the valve stem end cover (8). The control cavity is provided with an inverted frustum-shaped lock block (23). The upper end of the lock block (23) and the top wall of the control cavity are fixedly connected with a spring (24). The control cavity contains multiple balls (26) located outside the lock block (23). Multiple round holes are provided on the inner wall of the control cavity. An annular groove (22) is provided on the inner wall of the valve stem end cap (8) at the corresponding position in the control cavity. The end of the ball (26) away from the lock block (23) passes through the corresponding round hole and is inserted into the annular groove (22). A key slot is provided on the side above the valve stem end cap (8) of the magnetic anti-theft lock cover (14). A lock block magnet (25) is fixedly embedded at the upper end of the lock block (23). A key built-in magnet (28) is fixedly embedded at the lower end of the key (27).

[0004] At present, the magnetic anti-theft structure is relatively simple, and the above structure may have the disadvantage of being inconvenient to assemble. In addition, the spring (24) is a non-magnetic spring, which is generally made of copper spring and is also slightly more expensive. Utility Model Content

Detailed Implementation

[0021] The following describes a specific embodiment of the present invention in detail with reference to the accompanying drawings. However, it should be understood that the scope of protection of the present invention is not limited to the specific embodiment.

[0022] Example 1:

[0023] like Figure 1 As shown, a fully welded dustproof and anti-theft lock valve includes a valve body 1, a sealing valve seat 2, a ball 3, and a valve stem 4. The valve body 1 includes forged left and right bodies 11 and forged intermediate body 12. The forged left and right bodies 11 and the forged intermediate body 12 are formed by full welding. The valve body 1 is made of forged steel and connected by welding, which can avoid the process defects of castings and improve the quality of the product.

[0024] In some embodiments, an antistatic component 5 is provided between the lower end of the valve stem 4 and the ball 3, and the antistatic component 5 is an antistatic ball.

[0025] Example 2:

[0026] Combination Figure 2-4As shown, an anti-theft component is provided above the valve stem 4. The anti-theft component is a magnetic anti-theft component 6, which includes a lock sleeve 61 and a magnetic lock assembly. The lock sleeve 61 is connected above the valve stem sleeve 7, and the upper end of the valve stem 4 is built into the lock sleeve 61. The magnetic lock assembly includes a lock housing 62, a magnetic key 63, and a magnetic lock block 64. The upper end of the lock housing 62 is provided with a slot 65 for inserting the magnetic key 63. The magnetic lock block 64 is provided below the slot 65. The magnetic lock block 64 moves up and down along the lock housing 62. Several elastic joints are provided between the bottom of the magnetic lock block 64 and the bottom of the lock housing 62. The elastic element 66 provides an upward force to the magnetic lock block 64. The magnetic key 63 and the magnetic lock block 64 are respectively provided with a first magnet 631 and a second magnet 641. The inner wall of the lock sleeve 61 is provided with an annular groove 611, and a plurality of balls 67 are fitted in the annular groove 611. The balls 67 are limited to fit in the annular groove 611. The lock housing 62 is provided with a corresponding ball movement hole 621. The magnetic lock block 64 is provided with a conical structure 68 that cooperates with the balls 67. Specifically, the elastic element 66 is a compression spring, and the first magnet 631 and the second magnet 641 are both a plurality of correspondingly arranged magnets.

[0027] When the magnetic key 63 is inserted into the slot 65, the first magnet 631 on the magnetic key 63 and the second magnet 641 on the magnetic lock block 64 repel each other due to their similar poles. The magnetic lock block 64 will overcome the force of the elastic element 66 and move downward. Due to the cooperation between the cone structure 68 and the ball 67, the ball can roll down to the cone structure 68, that is, the ball 67 leaves the limit position. At this time, the magnetic lock assembly can be separated and removed. When the magnetic key 63 is pulled out, the repulsive force disappears, the elastic element 66 pushes the magnetic lock block 64 back to its original position, and under the action of the cone structure 68, the ball 67 returns to the limit position and limits the annular groove 611, that is, it is in a locked state.

[0028] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
