Problems solved by technology

Under vibration conditions, the loosening of the nut directly leads to the failure of the thread seal and water leakage
The connection method of quick connector is widely used in daily life because of its simple installation and disassembly. It is characterized by multi-channel sealing, and the reliability of parts is reduced. It is suitable for pipeline systems with large flow, but most of them have small diameter and flow resistance. Large and made of metal

Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] The novel self-locking water joint for a DC converter valve of the present invention includes a water nozzle, a positioning pin, a stepped pipe, a sealing ring, a nut and a snap ring. Such as Figure 1-2 As shown, stepped tube with sealing ring (such as image 3 ) is inserted into the faucet of the equipment body, under the action of the nut pre-tightening force, the sealing ring is pressed against the bottom surface of the faucet, and the pre-compressed sealing ring and the end face form a sealing effect; the nut is locked and connected with the inner thread of the faucet, And press on the outer edge of the stepped pipe; the stepped pipe with the sealing ring and the bottom surface of the faucet form an end face seal under the pre-compression condition of the sealing ring to prevent water from flowing out from the inner wall of the water pipe. When ...

Abstract

The invention provides a self-locking type water connector for a direct flow converter valve. The water connector specifically comprises a main body, a water nozzle, a step pipe and a nut which are sequentially arranged. The water connector is characterized in that a groove used for placing a sealing ring is arranged at one end of the step pipe, and the nut is connected with the water nozzle and is sleeved on the outside of the step pipe. The water connector can achieve the aims of being high in water pressure resistance, capable of bearing 2MPa working water pressure in long term, large in through diameter, small in flow resistance, high in self-sealing performance, good in corrosion resistance and anti-shock performance, convenient to install, capable of ensuring long-time high-reliability work and capable of being separated when the connector is used to facilitate replacement and maintenance of the equipment.

Description

technical field [0001] The invention belongs to the field of power electronics, and in particular relates to a self-locking water joint for a DC converter valve. Background technique [0002] The water cooling system is widely used in the cooling of DC converter valves at present, and the performance of the pipe joints of the water cooling system directly affects the sealing and reliability of the water system. In practical engineering applications, leakage and blockage accidents caused by unreasonable design and use of water joints are not uncommon. Therefore, reasonable design and selection of water joints are very important for long-term reliable operation of diverter valves. [0003] There are two main ways to connect water pipes to equipment at present, one is to use tapered thread sealing; the other is to connect with quick connectors. The tapered thread sealing feature achieves the sealing effect through the precise engagement of the tapered thread, and needs to use ...
