Description
Technical field:
The utility model relates to valve technology field, specifically a kind of four-way change-over valve.
Background technique:
Valve is the controlling component in fluid delivery system, has cut-off, adjustment, water conservancy diversion, prevents the functions such as adverse current, voltage stabilizing, shunting or overflow pressure relief.For the valve of liquid control system, various valves used from the simplest stop valve to very complicated robot control system(RCS), its kind and specification are quite various.Valve can be used for the flowing controlling all kinds fluids such as air, water, steam, various Korrosionsmedium, mud, oil product, liquid metal and radiating medium.The commutation of existing change-over valve is fairly simple, can only realize one or two fixing commutations, need just to have to use multiple selector valve during multiple reversing mode, use inconvenience.
Model utility content:
Technical problem to be solved in the utility model is to provide a kind of easy to use, and convenient operation, can realize the four-way change-over valve that four connecting tubes commutate arbitrarily.
Solve technical problem adopt following technological scheme:
A kind of four-way change-over valve, it is characterized in that: comprise valve body, valve gap, solid of rotation, running shaft and turning handle, the outside of described valve body is evenly provided with four connecting tubes be communicated with valve inner, described valve bonnet seal is arranged on the top of valve body, the rotatable inside being arranged on valve body of described solid of rotation, described running shaft is fixedly installed on the neutral position of solid of rotation and extends to the top of valve gap, described turning handle is fixedly installed on the rotary shaft, the inside of described solid of rotation is provided with two curved channels about solid of rotation central position symmetry, the two ends of curved channel are positioned at the sidepiece of solid of rotation, when curved channel one end is corresponding with the connecting tube of a valve body outside the other end of curved channel and another adjacent connecting tube corresponding, in valve inner, side is provided with a straight passage, straight passage is through the inside of running shaft, the two ends of straight passage are positioned at the sidepiece of solid of rotation, time corresponding with the connecting tube of a valve body outside when straight passage one end the other end of straight passage and another relative connecting tube corresponding.
The inside of described valve body and the sidepiece link position of solid of rotation are provided with seal ring.
The beneficial effects of the utility model are: the utility model is easy to use, convenient operation, can realize four connecting tubes and commutate arbitrarily.
Accompanying drawing illustrates:
Fig. 1 is the main TV structure schematic diagram of the utility model.
Fig. 2 is the utility model plan structure schematic diagram.
Embodiment:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As illustrated in fig. 1 and 2, a kind of four-way change-over valve, comprise valve body 1, valve gap 2, solid of rotation 3, running shaft 4 and turning handle 5, the outside of valve body 1 is evenly provided with four connecting tubes 6 be communicated with valve body 1 inside, valve gap 2 sealing is arranged on the top of valve body 1, the rotatable inside being arranged on valve body 1 of solid of rotation 3, running shaft 4 is fixedly installed on the neutral position of solid of rotation 3 and extends to the top of valve gap 2, turning handle 5 is fixedly installed on running shaft 4, the inside of solid of rotation 3 is provided with two curved channels 7 about solid of rotation 3 central position symmetry, the two ends of curved channel 7 are positioned at the sidepiece of solid of rotation 3, when curved channel 7 one end is corresponding with the connecting tube 6 of valve body 1 outside the other end of curved channel 7 and another adjacent connecting tube 6 corresponding, in valve body 1 inside, side is provided with a straight passage 8, straight passage 8 is through the inside of running shaft 4, the two ends of straight passage 8 are positioned at the sidepiece of solid of rotation 3, time corresponding with the connecting tube 6 of valve body 1 outside when straight passage 8 one end the other end of straight passage 8 and another relative connecting tube 6 corresponding.The inside of valve body 1 and the sidepiece link position of solid of rotation 3 are provided with seal ring 9.
More than show and describe basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
