Problems solved by technology
[0003] The current flow valve mainly has the following problems in the process of use: a: The connection between the flow valve and the pipe fittings is usually connected by welding, which makes it difficult to disassemble the pipe fittings and the flow valve; b: The flow display of the flow valve is usually related to the The rotary switch is matched together, resulting in the existing flow valve is very easy to cause inaccurate indication when the switch is turned, and the sealing of the flow valve is likely to be deteriorated by turning the switch multiple times

The invention provides a precision control liquid flow valve, which comprises a T-shaped sleeve, end connection units, a locking adjusting unit and a flow control unit, wherein the end connection units are respectively arranged in circulating ports in the two ends of the T-shaped sleeve in a threaded connection manner; the flow control unit is arranged on the upper end face of the middle of the T-shaped sleeve in a rotary connection manner; and the locking adjusting unit is arranged on the lower end face of the middle of the T-shaped sleeve in a clamping manner. The precision control liquid flow valve can solve the problems mainly existing in a using process of an existing flow valve, and the problems are as follows: a, when the flow valve is connected to a pipe fitting, a welding manner is usually adopted for connection, so that the pipe fitting and the flow valve are not prone to disassembly; and b, the flow display of the flow valve is usually matched with switch screwing to easilycause inaccurate indication when the existing flow valve carries out switch screwing, and the poor sealing performance of the flow valve is easily caused by screwing the switch for many times.
Description
technical field [0001] The invention relates to the technical field of valves, in particular to a precision control liquid flow valve. Background technique [0002] The flow valve is composed of a manual regulating valve group and an automatic balancing valve group. The role of the regulating valve group is to set the flow rate, and the function of the automatic balancing valve group is to maintain a constant flow rate. The flow valve is suitable for water systems that require flow control, especially for flow control of non-corrosive liquid media such as heating and air conditioning; installed in water systems, the system flow can be automatically constant after one adjustment before operation at the requested setpoint. [0003] The current flow valve mainly has the following problems in the process of use: a: The connection between the flow valve and the pipe fittings is usually connected by welding, which makes it difficult to disassemble the pipe fittings and the flow ...
