Abstract
The utility model discloses a two-position two-way mechanically-operated change valve. The two-position two-way mechanically-operated change valve comprises a valve body and is characterized in that the two-position two-way mechanically-operated change valve further comprises a valve element, a stop dog, a roller and a spring, a valve cavity is formed in the valve body, the valve element is arranged in the valve cavity, an oil inlet and an oil return port are formed in the valve body, one end of the spring is connected with the bottom of the valve body, the other end of the spring is connected with the bottom of the valve element, the roller is arranged at the top end of the valve element, the stop dog is arranged beside the roller, and a driving mechanism can control the stop dog to move so as to drive the roller to move downwards. The two-position two-way mechanically-operated change valve solves the problems that because a change valve in the prior art is controlled manually, the control precision is poor, the change valve is not convenient to control, meanwhile, because the current change valve is complex in structure, parts are very prone to damage, and the usage cost is sharply increased. The two-position two-way mechanically-operated change valve is simple in structure, convenient to use, not prone to damage and long in service life, and is high in control precision and stable and safe in control because control is performed in the mechanical mode.
Description
Technical field
The utility model relates to a kind of selector valve, particularly relates to a kind of bi-bit bi-pass servomotor driven change valve.
Background technique
Selector valve is the position control valve with two or more liquid forms and two above hydraulic fluid ports.Communication, cut-out and the commutation that realizes hydraulic oil stream, and the valve of discharge degree and sequentially-operating control.And current selector valve adopts manual control, control accuracy is poor, and it is also convenient not to control, and because structure of reversing valve is complicated at present, component very easily damage, and have significantly promoted user cost simultaneously.
Model utility content
In order to solve selector valve in prior art, adopt manual control, control accuracy is poor, and it is also convenient not to control, simultaneously because structure of reversing valve is complicated at present, component very easily damage, and have significantly promoted the problem of user cost, and it is a kind of simple in structure that the utility model provides, easy to use, employing machinery type is controlled, and control accuracy is high, controls stability and safety, and not fragile, the bi-bit bi-pass servomotor driven change valve of long service life.
In order to address the above problem, technical solution adopted in the utility model is:
A kind of bi-bit bi-pass servomotor driven change valve, comprise valve body, it is characterized in that: also comprise spool, link stopper, roller and spring, be provided with valve pocket in valve body, described spool is arranged in valve pocket, on valve body, be provided with filler opening and return opening, described spring one end is connected with valve body bottom, and the described spring the other end is connected with spool bottom, on the top of spool, is provided with roller, at the other link stopper that is provided with of roller, described driving mechanism can be controlled link stopper and move and drive roller to move down.
Aforesaid a kind of bi-bit bi-pass servomotor driven change valve, is characterized in that: described link stopper and roller contact face are inclined-plane.
The beneficial effects of the utility model are: the utility model bi-bit bi-pass servomotor driven change valve, when normality, spool under the effect of spring in upper, filler opening and return opening do not communicate, and when driving mechanisms control link stopper moves, link stopper is pushed down roller by inclined-plane, spool is moved down, filler opening and return opening communicate, and the utility model is simple to operate, easy to use, and control by machinery, control accuracy is high, can not damage, and working life is longer.
Accompanying drawing explanation
Fig. 1 is the utility model bi-bit bi-pass servomotor driven change valve structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, a kind of bi-bit bi-pass servomotor driven change valve, comprise valve body 1, spool 2, link stopper 3, roller 4 and spring 5, in valve body 1, be provided with valve pocket, described spool 2 is arranged in valve pocket, on valve body 1, be provided with filler opening 6 and return opening 7, described spring 5 one end are connected with valve body 1 bottom, described spring 5 the other ends are connected with spool 2 bottoms, on the top of spool 2, be provided with roller 4, at the other link stopper 3 that is provided with of roller 4, described driving mechanism can be controlled link stopper 3 and move and drive roller 4 to move down.Described link stopper 3 is inclined-plane with roller 4 surface of contact.
In sum, the utility model bi-bit bi-pass servomotor driven change valve, when normality, spool 2 is in upper under the effect of spring 5, and filler opening 6 and return opening 7 do not communicate, when driving mechanisms control link stopper 3 moves, link stopper 3 is pushed down roller 4 by inclined-plane, and spool 2 is moved down, and filler opening 6 and return opening 7 communicate, the utility model is simple to operate, easy to use, and control by machinery, control accuracy is high, can not damage, working life is longer.
More than show and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of 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.
Claims (2)
1. a bi-bit bi-pass servomotor driven change valve, comprise valve body, it is characterized in that: also comprise spool, link stopper, roller and spring, be provided with valve pocket in valve body, described spool is arranged in valve pocket, on valve body, be provided with filler opening and return opening, described spring one end is connected with valve body bottom, and the described spring the other end is connected with spool bottom, on the top of spool, is provided with roller, at the other link stopper that is provided with of roller, described driving mechanism can be controlled link stopper and move and drive roller to move down.
