Description

Technical Field

[0002] Double-acting throttling stop valve, as the name implies, is a valve that can perform throttling and shutoff functions, and double-acting means that the valve needs to input both positive and negative signals at the same time to operate, so as to achieve two-way control of the switch. Double-acting throttling stop valve is mainly used for pipeline control in hydraulic systems. Double-acting throttling stop valve is required when laying and installing air-conditioning pipelines to control the flow of refrigerant. At present, double-acting throttling stop valves are often installed and connected to air-conditioning pipelines through threads, which requires the connecting pipe to be rotated during installation, affecting the installation efficiency. Therefore, a double-acting throttling stop valve is needed.

[0003] The existing double-acting throttling stop valve is inconvenient to install the air conditioning connecting pipe when in use, and it is inconvenient to buffer the high-speed fluid, which causes the valve core to be worn by impact, affecting the service life of the double-acting throttling stop valve. Therefore, a double-acting throttling stop valve is urgently needed. Utility Model Content

[0009] Preferably, the second half-threaded column is threadedly connected to the nut, and the second half-threaded column is adapted to the first half-threaded column.

[0010] Preferably, the double-acting throttle stop valve housing is of slotted design, and the double-acting throttle stop valve housing and the first buffer plate form a sliding structure.

[0011] Preferably, a spring is fixedly connected to one side of the first buffer plate, and the spring is arranged in a ring shape with the central axis of the first buffer plate as the center.

[0012] Preferably, the second buffer plate and the double-acting throttling stop valve housing form a sliding structure, and the second buffer plate is arranged parallel to the first buffer plate.

[0014] 1. The utility model is provided with a double-acting throttling stop valve housing, a connecting pipe, a first fixing plate, a first half-threaded column, a second fixing plate, a second half-threaded column and a nut. By moving the connecting pipe, one end of the connecting pipe is butt-jointed and inserted into the double-acting throttling stop valve housing, the first fixing plate is clamped at the connection between the double-acting throttling stop valve housing and the connecting pipe, the second fixing plate is pulled so that the second fixing plate is turned along the first fixing plate, driving the second half-threaded column to merge and close with the first half-threaded column, and by moving the nut to one end of the second half-threaded column and rotating the nut, the second half-threaded column and the first half-threaded column can be tightened, thereby facilitating the installation and connection of the double-acting throttling stop valve housing and the connecting pipe;

[0015] 2. The utility model provides a double-acting throttling stop valve housing, a connecting pipe, a first buffer plate and a second buffer plate.
