Description

Manual regulating valve capable of preventing misoperation Technical Field The utility model relates to the technical field of valves, in particular to a manual regulating valve capable of preventing misoperation. Background In heating, central air conditioning and user heating systems, manual regulating valves are used as key components for controlling fluid flow, and play a vital role in guaranteeing stable operation of the system and meeting use requirements of users, however, many problems to be solved in practical application exist in the traditional manual regulating valves. The conventional manual regulating valve lacks an anti-misoperation mechanism, and in the running process of a system such as a heat supply system, a central air conditioner and the like, the valve can be erroneously regulated due to negligence of operators, misoperation of non-professionals or other unexpected situations, so that abnormal flow of the system is caused. Disclosure of utility model (One) solving the technical problems Aiming at the defects of the prior art, the utility model provides the misoperation-preventing manual regulating valve, and solves the problem that the traditional manual regulating valve lacks an misoperation-preventing mechanism. (II) technical scheme The manual regulating valve comprises a valve body and a lock sleeve, wherein the inner wall of the lock sleeve is rotationally connected with the top of the valve body, the inner wall of the valve body is rotationally connected with a lock body through a regulating valve rod, a groove is formed in the inner wall of the lock body, the outer wall of the regulating valve rod is rotationally connected with the inner wall of the valve body, a temperature acquisition interface is inserted into the bottom of the valve body, and a V-shaped regulating ball body is rotationally connected with the inner wall of the valve body. Preferably, the valve seat is fixedly arranged on the inner wall of the valve body, and the top of the adjusting valve rod is fixedly connected with the bottom of the lock body. Preferably, the outer wall of the lock body is rotationally connected with the inner wall of the lock sleeve through a limiting ring, the outer wall of the limiting ring is fixedly connected with the inner wall of the lock sleeve, and the limiting ring is used for limiting the position of the lock body. Preferably, the outer wall of the limiting ring is rotationally connected with the outer wall of the lock body, and the bottom of the adjusting valve rod is fixedly connected with a connecting block. Preferably, the bottom of connecting block is pegged graft with the spheroidal top of V type regulation, the outer wall of connecting block is connected with the inner wall rotation of valve body, the outer wall of disk seat and the spheroidal outer wall sliding connection of V type regulation. (III) beneficial effects The utility model provides a manual regulating valve capable of preventing misoperation.
