Description
Technical field
The utility model relates to a kind of three-way valve structure.
Background technique
Three-way valve is the modulating valve with three outlets, is mainly used in the not occasion of conducting simultaneously of three road interfaces.Along with the progress of development of science and technology with society; People design different three-way valve as required; Electric three passes modulating valve for example, it is usually used in, and air conditioning, heat are ventilated, the industry of heat treatment factory and fluid control of industrial and commercial bank's industry, but the structure of prior electric three-way control valve generally comprises valve body; Be arranged on the synchronous machine of valve body outer upper end; Be positioned at spool, spring, the valve rod of valve body; Valve rod is connected with synchronous machine, and spool comprises upper piston, lower piston, and upper piston, lower piston all are fixedly installed on the valve rod; According to moving up and down of valve rod; Play the effect of regulating flow, spring is centered around on the valve rod, and its two ends are fixedly connected with the bottom of lower piston and valve body respectively.Such three-way valve structure need be provided with two pistons, when its cost is high; Take the area of fluid passage, the total discharge in the unit time is smaller, and spring is arranged in the fluid passage; Fluid influences the working life (make its elasticity diminishes, piston is not closed completely) of spring easily, thus the working life of having reduced three-way valve, and; The resistance of spring convection cell is big, and these all exist certain inconvenience.
The model utility content
The utility model technical problem to be solved is the deficiency that overcomes existing technology, provides that a kind of cost is low, resistance is little, can improve total discharge in the unit time, can improve the three-way valve structure in working life.
The technological scheme that the utility model adopted is: the utility model comprises valve body, spool, electric performance device, spring, valve rod; Said electric performance device is fixedly installed on the top in the said valve body outside; One end of said valve rod is connected with said electric performance device, and the other end is positioned at the fluid passage of said valve body, and said spool is arranged on and is positioned at said valve body on the said valve rod; Said spool comprises a piston; Be set with connecting sheet on the said valve rod, said spring is arranged on the said valve body outside around said valve rod, and the two ends of said spring are fixedly connected with said valve body with said connecting sheet respectively.
Said electric performance device is a synchronous machine.
The beneficial effect of the utility model is: because the said spool of the utility model comprises a piston, reduced by a piston like this, when practicing thrift cost; Can reduce the occupation area of spool in said valve body; Be set with connecting sheet on the said valve rod, said spring is arranged on the said valve body outside around said valve rod, and the two ends of said spring are fixedly connected with said valve body with said connecting sheet respectively; Can reduce the resistance of convection cell like this; And said spring can be avoided weakening because of the influence elasticity that receives fluid for a long time, so the utility model cost is low, resistance is little, can improve total discharge in the unit time, can improve working life.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1, the utility model comprises valve body 1, spool, electric performance device 2, spring 3, valve rod 4, and said electric performance device 2 is a synchronous machine; Said electric performance device 2 is fixedly installed on the top in said valve body 1 outside, and an end of said valve rod 4 is connected with said electric performance device 2, and the other end is positioned at the fluid passage of said valve body 1; And the contacting point of itself and said valve body 1 all is sealed and matched, and said spool is arranged on and is positioned at said valve body 1 on the said valve rod 4, and said spool comprises a piston 5; Be provided with last gear and the lower gear adaptive with said piston 5 in the said valve body 1, said piston 5 moves up and down with said valve rod 4, goes up the cooperation that contacts of gear and said lower gear with said respectively; Realize the adjusting of fluid, reduced by a piston like this, when practicing thrift cost; Can reduce the occupation area of said spool in said valve body 1, can improve the total discharge in the unit time, be set with connecting sheet 6 on the said valve rod 4; Said spring 3 is arranged on said valve body 1 outside around said valve rod 4; The two ends of said spring 3 are fixedly connected with said valve body 1 with said connecting sheet 6 respectively, can reduce the resistance of convection cell like this, and; Said spring 3 can be avoided weakening because of the influence elasticity that receives fluid for a long time; Thereby cause three-way valve not use and need changing, can guarantee the normal use of said spring 3, thereby effectively raise the working life of three-way valve.
The utility model can be widely used in the three-way valve field.
Claims (2)
1. three-way valve structure; It comprises valve body (1), spool, electric performance device (2), spring (3), valve rod (4); Said electric performance device (2) is fixedly installed on the top in said valve body (1) outside; One end of said valve rod (4) is connected with said electric performance device (2), and the other end is positioned at the fluid passage of said valve body (1), and said spool is arranged on and is positioned at said valve body (1) on the said valve rod (4); It is characterized in that: said spool comprises a piston (5); Be set with connecting sheet (6) on the said valve rod (4), said spring (3) is arranged on said valve body (1) outside around said valve rod (4), and the two ends of said spring (3) are fixedly connected with said valve body (1) with said connecting sheet (6) respectively.
