Abstract
The utility model discloses a special valve. The special valve comprises a valve body and a valve block, and is characterized in that the valve block is cylindrical, a rotary shaft is arranged in the direction of the axis of the valve block, the valve body is arranged outside the valve block in a covering mode, four openings are formed in each of the two sides of the valve body, and are arranged around the rotary shaft in an annular mode, two through holes are formed in the valve block and are arranged around the rotary shaft, the valve block can rotate in the valve body through the rotary shaft so that the two through holes can be communicated with the openings, the section of each opening and the section of each through hole are circles with the same size, the distance between the center of each through hole and the rotary shaft is equal to that between the center of the corresponding opening and the rotary shaft, the centers of the two through holes and the center of the rotary shaft are located on the same straight line, and pipeline connecting pipes are connected to the outer sides of the openings respectively.
Description
Technical field
The utility model belongs to valve field, particularly a kind of Special valve.
Background technique
Valve is the controlling component in fluid delivery system, has cut-off, adjusting, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of liquid control system, from the simplest stop valve to very complicated robot control system(RCS) various valves used, its kind and specification are quite various.Valve can be used for controlling flowing of all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.
Valve is according to being divided into by effect and purposes: block class: its effect is to connect or block the medium in pipeline.Safety check, its effect is to prevent that the medium in pipeline from flowing backwards, preventing pump and drive motor reversion, and the leakage of vessel media.Explosion-proof valve, guard valve etc., the effect of safety valve is to prevent that the pressure medium in pipeline or device from exceeding specified value, thereby reaches the object of safety protection.Modulating valve, throttle valve and reduction valve, its effect is the parameter such as pressure, flow that regulates medium.
Vacuum types: its effect is in vacuum system, is used for changing airflow direction, regulates throughput size, and the vacuum system element that cuts off or connect pipeline is called vacuum valve.
At present, open multiple valves in application, also close multiple valves, this all needs open and close one by one, lacks a kind of valve that facilitates open and close handover operation simultaneously.
Summary of the invention
The purpose of this utility model is to provide two pipelines of a kind of convenient opening and closing simultaneously, the Special valve that can facilitate pipeline to switch mutually.
Special valve of the present utility model, comprises valve body and valve piece, and being shaped as of described valve piece is cylindric, is provided with rotating shaft along the shaft core position of valve piece; Described valve body is wrapped in valve piece outside, and the both sides of valve body are respectively arranged with four openings around described rotating shaft annular array; Described valve piece is provided with two through holes around rotating shaft, and described valve piece can rotate by rotating shaft in valve body, so that two through holes are connected with opening respectively.
As optimization, described opening is with the cross section of described through hole the circle that size is identical.The center of described through hole is identical to the distance of rotating shaft with the center of described opening to the distance of rotating shaft.The center of described two through hole is positioned at straight line with spindle central.The outside of described opening is connected with respectively connecting pipe of pipeline.
When use, pipeline amounts to eight openings by valve both sides respectively and connects with valve, and by rotating shaft rotary valve piece, valve piece can be opened wherein two valves, or switches to and open two other valve.By the utility model Special valve, the operation while having facilitated valve opening.By once-through operation, can open two valves, close two valves simultaneously, facilitate use.
