Abstract
The utility model discloses a novel bidirectional valve which is mainly composed of the following components: a valve body, a valve cover, a rubber valve core and mounting screws. The bidirectional valve has the following advantages: simple and compact structure, and high integration level. The bidirectional valve receives pressure air signals which are transmitted from two ends, and realizes output of the gas at a high-pressure side through an outlet of the valve body through the left-and-right movement of the middle rubber valve core. The novel bidirectional valve is suitable for a state that the output pressure is determined by the air pressure signals of the two ends.
Description
Technical field
The utility model relates to a kind of novel two-way valve.
Background technique
The two-way valve internal structure complexity of existing general structure, the sealing valve port performance is bad, sews easily, and the rate that breaks down is higher, and is unsuitable for board-like installation.
Summary of the invention
Goal of the invention of the present utility model is: at the problem of above-mentioned existence, a kind of novel two-way valve is provided, it is characterized in that: this two-way valve comprises valve body, structure valve port, valve gap, rubber spool and mounting screw, described structure valve port is arranged at described valve inner, and described rubber spool is the structure of " Y " type lip shape.This two-way valve also comprises seal ring.This two-way valve mainly is made up of valve body, valve gap, rubber spool and mounting screw, and is simple and compact for structure, and level of integration height, valve port are located at metal valve body inside.Show as Fig. 1, when pressure air P1＞P2, valve port is opened, P1 is exported by delivery outlet through the valve inner path, P0=P1, at this moment, because rubber spool " Y " shape lip seal structure Design, the tension force of depended on pressure air is pressed on spool edge on the valve interior wall, has realized the seal action to the P2 end.Show that as Fig. 2 when pressure air P1＜P2, P2 pushes the rubber spool to the valve port place, valve port is closed, and simultaneously, because the effect of pressure air, " Y " shape lip of rubber spool is tightened up, and pressure air P2 is exported by delivery outlet through the valve body inner gateway, P0=P2.In addition, because the ingenious design of mounting screw position makes screw not only play the effect of installation, and, also valve gap is played backstop action, make the position relative fixed of valve gap.
In sum, owing to adopted technique scheme, products characteristics of the present utility model and beneficial effect are: this two-way valve is simple and compact for structure, and volume is little, and is in light weight, and technology capability is good, is convenient to assembling, and mounting type is also very simple.And the design principle of this valve is simple, reliable effect, and rate of fault is low.This two-way valve receives the pressure air signal that two ends are transmitted, and realizes that by the side-to-side movement of middle part rubber spool the gas of the higher side of pressure exports by valve outlet.Be applicable to the situation that decides delivery pressure by two ends air pressure signal.
Description of drawings
The utility model will illustrate by example and with reference to the mode of accompanying drawing, and wherein: Fig. 1 is the utility model structural representation when working as P1＞P2.1-valve body wherein; The 2-valve gap; The 3-seal ring; 4-rubber spool; The 5-seal ring; The 6-screw.
Fig. 2 is the utility model structural representation when working as P1＜P2.
Embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
In order to make the purpose of this utility model, technological scheme and advantage clearer,, the utility model is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
As shown in Figure 1, when pressure air P1＞P2, valve port is opened, P1 is exported by delivery outlet through the valve inner path, P0=P1, at this moment, because rubber spool " Y " shape lip seal structure Design, the tension force of depended on pressure air is pressed on spool edge on the valve interior wall, has realized the seal action to the P2 end.
As shown in Figure 2, when pressure air P1＜P2, P2 pushes the rubber spool to the valve port place, and valve port is closed, and simultaneously, because the effect of pressure air, " Y " shape lip of rubber spool is tightened up, and pressure air P2 is exported by delivery outlet through the valve body inner gateway, P0=P2.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
Claims (2)
