Abstract
The utility model discloses a novel two-position three-way valve and belongs to the mechanical field of pipelines. The two-position three-way valve comprises a valve inlet, a valve outlet, an instruction connector, a bypass outlet, a valve membrane, a valve rod, a valve plate and a valve spring, wherein the valve inlet, the valve outlet, the instruction connector and the bypass outlet form an integrated structure of a valve outer shell, one end of the valve membrane is connected with the upper portion of the valve outer shell, the other end of the valve membrane is connected with one end of the valve rod, the other end of the valve rod is connected with one end of the valve plate, the other end of the valve plate is connected with one end of the valve spring, and the other end of the valve spring is fixed on the lower portion of the valve outer shell. When the improved two-position three-way valve is in a normal open state and in a reverse working state, the valve membrane, the valve rod and the valve outer shell are not in direct friction motion on surfaces, thereby the service life of the valve is greatly increased, and the improved two-position three-way valve is convenient to repair and disassemble.
Description
Technical field
The utility model relates to a kind of novel two-bit triplet valve, belongs to the pipeline mechanical field.
Background technique
Two-bit triplet valve inner spool commonly used adopts barrier film to add piston cylinder operator mostly; The working principle of this type of valve is that diaphragm of rubber drives the valve rod action; Valve rod drives the piston valve core action; Thereby accomplish the keying of valve, because the back flush valves frequency of okperation is higher relatively, the guide rod of back flush valves, piston or valve plate ratio are easier to wearing and tearing take place and damage.
The model utility content
This is novel to be to overcome that existing two-bit triplet valve commonly used weares and teares easily and the problem damaged provides a kind of novel two-bit triplet valve.
In order to solve the problems of the technologies described above, the utility model provides following technological scheme:
A kind of novel two-bit triplet valve; Comprise valve inlet, valve export, instruction interface tube, lie outlet, valve barrier film, valve rod, valve plate and valve spring; Said valve inlet, valve export, instruction interface tube and lie export mixes valve housing are integral structure; Said valve housing top connects valve barrier film one end, and the said valve barrier film the other end connects valve rod one end, and institute's valve rod the other end of telling connects valve plate one end; The said valve plate the other end connects valve spring one end, and the said valve spring the other end is fixed on the valve housing bottom.
As preferably, said valve inlet one end is provided with boss.
As preferably, said valve barrier film is divided into link together two-layer up and down, and said valve barrier film adopts the compound rubber of high tenacity.
The utility model has the following advantages and characteristics owing to adopted above technological scheme:
Novel two-bit triplet valve after the improvement is at normally open and reverse operation state, and valve barrier film, valve rod, valve housing all do not have surperficial direct friction motion, has therefore increased the working life of valve greatly, and the two-bit triplet valve maintenance after the improvement is disassembled conveniently.
Description of drawings
Accompanying drawing is used to provide the further understanding to the utility model, and constitutes the part of specification, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:
Fig. 1 is the valve normally open schematic representation of the utility model;
Fig. 2 is the reverse operation view of the utility model.
Embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
Like Fig. 1, shown in Figure 2; A kind of novel two-bit triplet valve; Comprise valve inlet 1, valve export 2, instruction interface tube 3, lie outlet 6, valve barrier film 4, valve rod 8, valve plate 5 and valve spring 7, it is integral structure that valve inlet 1, valve export 2, instruction interface tube 3 and lie outlet 6 constitute valve housing, and valve housing top connects valve barrier film 4 one ends; Valve barrier film 4 the other ends connect valve rod 8 one ends; Institute's valve rod the other end of telling connects valve plate 5 one ends, and the valve plate the other end connects valve spring 7 one ends, and the valve spring the other end is fixed on the valve housing bottom.
Valve inlet one end is provided with boss.The valve barrier film is divided into link together two-layer up and down, and the valve barrier film adopts the compound rubber of high tenacity.
Modified model valve barrier film has two functions: power is provided, self opens and closes function to valve rod, valve makes valve barrier film, valve rod and valve housing reduce wearing and tearing to greatest extent after improving.
Valve normally open (working state), the instruction pipe is left a blank, and chamber of septum liquid is discharged; Because the effect of fluid pressure, the valve barrier film moves up, discharges water or the air in the chamber of septum, and drives valve pull rod; Then close valve plate, at this moment valve inlet, valve export conducting.
The reverse operation state; Controlled water flow gets into chamber of septum through the instruction interface tube; Along with moving down and promote valve rod, the rising valve barrier film of pressure backs down valve plate; The valve barrier film closely contacts with valve housing inner convex platform arcuate structure under the effect of chamber of septum fluid pressure simultaneously, blocking-up valve inlet, valve export and lie outlet conducting this moment.
Two-bit triplet valve after the improvement is under above-mentioned two states, and valve barrier film, valve rod, valve housing, valve plate all do not have surperficial direct friction motion, has therefore increased the working life of valve greatly, and the two-bit triplet valve maintenance after the improvement is disassembled conveniently.
What should explain at last is: the above is merely the mode of execution of explanation the utility model; Be not limited to the utility model; For a person skilled in the art; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
