Problems solved by technology

[0003] However, the valve stems in the existing valves are all fixedly connected to the valve. When the valve stem needs to be replaced, the entire valve can only be disassembled, which increases the maintenance cost and reduces the work efficiency. Moreover, maintenance is not easy. Convenience, when the valve stem of different size is needed, only the whole valve can be replaced, which greatly increases the cost, and at the same time, the valve stem on the valve body is inconvenient to replace

Abstract

The invention discloses a valve with a detachable valve rod. The valve with the detachable valve rod comprises a valve body, an adapter, a valve rod, a fixing plate or a hand wheel. The adapter is arranged at the top of the valve body, and the valve rod is arranged on one side of the adapter. The fixing plate is arranged on the side, away from the adapter, of the valve rod. The hand wheel is arranged at one side, away from the valve rod, of the fixing plate, wherein a cavity body is formed in the adapter. A first fixing column is arranged at one end of the upper portion of the interior of thecavity, and a rotary shaft is arranged on the middle portion of the first fixing column in a penetrating and inserting mode. A motor is arranged the end, away from one end of the first fixing column,of the rotary shaft. A first pin gear is arranged between the motor and the first fixing column and located on the surface of the rotary shaft in a sleeving mode. The valve with the detachable valve rod has the beneficial effects that the cost of maintaining the whole valve is reduced, the connectivity between the valve rod and the valve body is convenient, the valve rod of the valve body is convenient to change, and the valve is convenient to use.

Description

Technical field [0001] The invention relates to the technical field of valves, and in particular to a valve with a detachable valve stem. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. According to its function, it can be divided into shut-off valve, check valve, regulating valve and so on. The valve is a control component in the fluid conveying system, which has the functions of cut-off, regulation, diversion, prevention of backflow, stabilization, diversion or overflow and pressure relief. Valves used in fluid control systems, ranging from the simplest shut-off valve to the various valves used in extremely complex automatic control systems, have a wide variety and specifications. Prior art 1: CN206846062 discloses a valve with a detachable stem, including a valve body, a valve stem, and a valve shaft. The valve shaft is in...
