Description

Technical Field

[0001] This utility model relates to the field of valve technology, specifically to a welded valve with magnetic locking function. Background Technology

[0002] Currently, most valves on the market are cast products, generally made of cast iron or copper. Stainless steel valves are more expensive and more difficult to manufacture. Conventional valves are cast in one piece, resulting in high processing costs and complex manufacturing processes. Sealing primarily relies on rubber covering the outer circumference of the valve core. Prolonged use causes frequent compression and aging of the rubber. Furthermore, if the medium in the pipeline contains impurities such as sand or iron filings, this structure will lose its sealing effect, affecting its service life. Utility Model Content

[0003] The technical problem this invention aims to solve is that valves produced using existing valve casting processes are costly and involve complex manufacturing processes.

[0004] To solve the above problems, the technical solution adopted by this utility model is a welded valve with magnetic locking function, including a valve body, a front valve plug and a rear sealing plug respectively welded and fixed at both ends of the valve body, a positioning hole is opened on the upper side of the valve body, a valve stem sleeve is fixed at the positioning hole on the upper side of the valve body, a valve ball is provided in the valve body, a valve stem is provided in the valve stem sleeve, the bottom end of the valve stem is fixed to the valve ball, a sleeve is welded and fixed at the top end of the valve stem sleeve, and a magnetic lock is provided in the sleeve.

[0005] As a further embodiment of this invention, an O-ring is provided on the outer side of the valve stem to achieve a sealing effect.

[0006] As a further embodiment of this invention, an O-ring and a PTFE gasket are provided between the valve ball and the valve body to achieve a sealing effect.

[0007] As a further embodiment of this utility model: a magnetic lock key is provided on the top of the magnetic lock, and a handle is fixed to one end of the magnetic lock key, which makes it easy to open the magnetic lock.

[0008] Compared with the prior art, the advantages of this utility model are as follows: This application solves the problems of high cost and complex process of casting products by welding and assembling valve structure, as well as valve sealing failure caused by factors such as rubber aging and impurities in the medium in the pipeline. The structure is reasonable, easy to assemble, and the addition of a magnetic lock structure can effectively prevent operation by unauthorized personnel. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] This utility model provides a technical solution to address the existing problems mentioned in the background art.

[0016] Combined with appendix Figure 1-2 It can be seen that the valve body 1 is provided. A front valve plug 2 and a rear sealing plug 8 are welded and fixed at both ends of the valve body 1. A positioning hole is opened on the upper side of the valve body 1. A valve stem sleeve 5 is fixed at the positioning hole on the upper side of the valve body 1. A valve ball 6 is provided inside the valve body 1. A valve stem 7 is provided inside the valve stem sleeve 5. The bottom end of the valve stem 7 is fixed to the valve ball 6. A sleeve 9 is welded and fixed at the top end of the valve stem sleeve 5. A magnetic lock 12 is provided inside the sleeve 9.

[0017] The valve stem 7 is fitted with an O-ring 10 on the outside to provide a sealing effect; the valve ball 6 and the valve body 1 are fitted with an O-ring 3 and a PTFE gasket 4 to provide a sealing effect; a magnetic lock key 13 is provided above the magnetic lock 12, and a handle 11 is fixed to one end of the magnetic lock key 13 to facilitate opening the magnetic lock 12.

[0018] Magnetic locking principle: Two retractable steel balls are embedded in the inner side limiters of the magnetic lock 12. When the magnetic lock key 13 is brought close to the magnetic lock 12, the steel balls will retract into the magnetic lock 12 due to magnetic attraction. When the magnetic lock key 13 is moved away from the magnetic lock 12, the steel balls will pop out due to the loss of magnetism and get stuck in the groove in the sleeve 9. This is existing technology and can be purchased on the market.

[0019] The working principle of this application is as follows: First, the front valve plug 2 and the valve body 1 are welded together. Then, the valve stem O-ring 10 is put onto the valve stem 7. The O-ring 3 and the PTFE gasket 4 are placed inside the valve body 1. The valve stem 7 is inserted from the valve body 1 into the valve stem bushing 5. The valve ball 6 is inserted into the valve body 1. The O-ring 3 and the PTFE gasket 4 are placed into the rear valve plug 8. The rear valve plug 8 and the valve body 1 are welded together using welding technology. Finally, the valve body 1 and the sleeve 9 are welded together.

[0020] To avoid misjudgment, enabling or disabling the linkage function should be linked to the payment function. That is, this function should only be enabled for users who have not paid, while users who have paid should not be judged by default, but can optionally retain this function.

[0021] During the non-heating season: the valve should remain in the state it was in before the end of the heating season. The pressure linkage function should be suspended during this period. After the normal heating season begins, the function should be restarted. The start and stop times should be determined by the cloud system.

[0022] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
