Description

Technical Field

[0001] This utility model relates to the field of heating valve control technology, and more specifically, to a lockable ball valve. Background Technology

[0002] Individual heating management involves installing separate valves to control the flow of heat into each household, achieving "one valve per household." Controlling the opening and closing of these valves allows for precise management of each user's heating behavior. These valves can be manual or electric. Electric valves are easier to control, but require an electric actuator for each valve and related equipment to communicate with the management system, resulting in a larger investment in the entire heating control system. For economic reasons, heating companies often choose manual valves as the mandatory control valves for each household; these manual valves are typically mechanically locked shut-off valves.

[0003] Currently, mechanically locked valves generally use magnetic locking, which locks the valve position based on the principle that like poles attract and unlike poles repel. Further upgrades have involved a combination of magnetic locking and a special-shaped key. For users who have suspended heating or are in arrears, the heating company uses a special magnetic key to shut off the valve, stopping heating for that user. Without the key, the user cannot open the valve, thus controlling heating supply according to actual payment status.

[0004] However, the existing mechanical locking method combining magnetism and irregularly shaped keys has the following security risks and drawbacks:

[0005] 1. Magnetic locks are relatively easy to crack. Outsiders can detect the magnetic polarity and match the lock cover structure to copy the key and illegally open the lock.

[0006] 2. Losing a key poses a risk of loss of control. Generally, the same type of shut-off valve is used in the same community. If the heating company's operator loses a key, it may expose the valves in the entire area to the risk of loss of control.

[0007] Currently, there are also electronic locking valves on the market that are authorized by electronic devices. However, the design and principle of existing electronic locking valves are simply to replace the opening and locking functions of mechanical keys with electronic keys. They do not completely eliminate the risks and problems that exist with mechanical locking valves. Utility Model Content

[0008] In view of this, the purpose of this utility model is to address the problems that easily occur in existing mechanical locking valves by designing a lockable ball valve. By designing the upper cavity structure of the valve body and combining it with a dedicated electronic lock head structure, it can prevent unauthorized opening of pipeline valves and ensure the safe operation of pipeline systems. The upper cavity of the valve body can house both the electronic lock head and a dedicated handwheel. It can not only unlock and unlock the valve through the electronic lock head, but also be used as a regular ball valve, achieving dual functionality. This saves on equipment procurement costs, installation costs, and time, and is convenient, quick, and widely applicable.

[0009] This utility model provides a lockable ball valve, comprising: a valve body, wherein an electronic lock head, a valve stem, and a valve ball are coaxially connected from top to bottom inside the valve body; the lower part of the valve body includes a first valve body and a second valve body connected by threads, and a PTFE valve seat is provided on each side of the valve ball, with each PTFE valve seat being embedded in the first valve body and the second valve body respectively.

[0010] Preferably, O-rings are respectively provided on the mating surfaces of the PTFE valve seat and the valve body one and the valve body two to achieve double-sided sealing between the valve ball and the valve body. The right side of the valve body two and the left side of the valve body one are tightly fitted, so that the PTFE valve seat and the valve ball are sealed and fitted, generating a uniform pre-tightening force and improving the sealing performance between the valve body and the valve ball.

[0011] Furthermore, the upper end of the valve ball is provided with a slot, and the valve stem passes through the upper cavity of the valve body from top to bottom and is inserted into the slot; the lower end of the electronic lock head is provided with a flat groove, and the upper part of the valve stem is provided with a flat rod, which is inserted into the flat groove.

[0012] Specifically, the upper cavity of the valve body is specially designed to house the electronic lock head and enable locking. The electronic lock head can be removed from the upper part of the valve stem and taken out from the upper cavity of the valve body.

[0013] Furthermore, the electronic lock cylinder includes: a lock cylinder housing, and inside the lock cylinder housing, from top to bottom, a lock cylinder cover, a core circuit board, an electromagnet, and a contact plate are arranged sequentially. The core circuit board is threadedly connected to the lock cylinder cover, and the lock cylinder cover and the electromagnet are respectively threadedly connected to the lock cylinder housing.

The probe passes through the circular hole and protrudes out of the circular hole. A circular hole is provided on the side of the lock housing, and the electromagnet includes a magnetic shaft. The magnetic shaft passes through the circular hole and protrudes out of the circular hole.

[0016] In one embodiment of this invention, a contact plate is installed on the lowermost side of the upper cavity of the lock head housing. Two probes on the contact plate pass through two circular holes on the lower side of the lock head housing. An electromagnet is placed on the upper end of the contact plate, and the magnetic shaft on the electromagnet passes through a circular hole on the side of the lock head housing. After the core circuit board and the lock head cover are fixed together, the lock head cover is installed on the lock head housing. When the electronic lock head is installed into the upper cavity of the valve body, the upper end of the valve stem will be inserted into the lower cavity of the lock head housing. After the electronic lock head is installed in place, the probes on the contact plate will contact the upper end face of the valve stem. The probes transmit the signal to the core circuit board through the pins on the contact plate. The core circuit board then transmits the signal indicating that the electronic lock head is installed in place to an external device.

[0017] Furthermore, the outer side of the lock housing is provided with a protruding structure, and the inner side of the valve body is provided with a groove that matches the protruding structure. The electronic lock head is inserted into the upper cavity of the valve body along the groove.

[0020] Furthermore, when the lockable ball valve does not need to be locked, the electronic lock head is replaced with a handwheel, which is detachably connected to the upper cavity of the valve body.

[0021] When the ball valve does not need to be locked, remove the electronic lock head and replace it with a dedicated handwheel. Place the dedicated handwheel in the upper cavity of the valve body, and the lockable ball valve can be turned into an ordinary openable and closable manual ball valve, realizing the function of one valve body for multiple purposes.

[0022] Furthermore, a plastic cover is provided on the upper part of the valve body, and a rubber gasket is provided between the plastic cover and the valve body. The plastic cover is threadedly connected to the valve body.
