A kind of HVAC heat supply replaceable core cock quick opening valve

Abstract

The invention provides a quick-opening valve with replaceable core cock for HVAC heating, which relates to the field of HVAC valves, and solves the problem that the sealing cover plate is rusted or the sliding wire cannot be disassembled; emergency locking cannot be realized, and it is easy to cause the inside of the HVAC pipeline. The water flow is scattered into the room; after the valve is blocked, the valve needs to be disassembled to clear the blockage. A HVAC quick-opening valve with a replaceable core cock, comprising a valve main body; the valve main body is threadedly connected with a locking structure. When the core body is damaged and needs to be replaced, the bolt B can be unscrewed and then the core body can be replaced. At this time, first, the insertion rod passes through the socket B and the socket A at the same time, and the handle and the insertion rod together form the bolt B The disassembly structure, so that the bolt B can be disassembled without a wrench, which facilitates the replacement of the core body; second, if the bolt B is rusted and cannot be disassembled and washed, because the bolt A and the bolt B together form a combined disassembly structure, when the rust is dead Thread removal bolt A can still realize the replacement of the valve core structure.

Description

technical field [0001] The invention belongs to the technical field of HVAC valves, and more specifically relates to a HVAC quick-opening valve with a replaceable core cock. Background technique [0002] At present, the structure of various new valves is becoming more and more perfect, and the performance is also very good, but its structure is becoming more and more complicated, the maintenance and maintenance measures are time-consuming and laborious, and the cost of maintenance and maintenance is still high. [0003] Based on the above, the existing HVAC valves still have the following deficiencies in use: [0004] First, when the existing replaceable core valve needs to be replaced, if the sealing cover plate is rusted or the sliding wire cannot be disassembled, it needs to be replaced as a whole; The water in the pipeline is scattered indoors; third, when the valve is blocked, the valve needs to be disassembled to clear the blockage, which is difficult and time-consumi...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above-mentioned technical problems, the present invention provides a quick-opening valve with replaceable core cock for heating, ventilation and heating, so as to solve the problem of the existing first. It will not be able to be disassembled and needs to be replaced as a whole; second, when the valve is damaged, it will not be able to achieve emergency locking, which will easily cause the water in the HVAC pipe to flow into the room; third, when the valve is blocked, the valve needs to be disassembled before installation. Clearing the blockage is difficult and time-consuming to maintain; fourth, a wrench is required for disassembly, and disassembly will not be possible without a wrench, and the problem of poor structural practicability
