Abstract
The utility model relates to a linear four-way fluid changeover valve, which is mainly used for gas changeover devices in the technical field of the pneumatic transportation. The utility model is composed of a valve body, a valve core, a valve cover, an end cover, a connecting piece, a pin shaft and a driving device, wherein the circumference of the valve body is provided with four holes communicated with a hollow cavity. The valve core divides the hollow cavity and the four holes into two parts, and under the function of the driving device, the valve core reciprocates linearly along the axial line of the valve body and is positioned by the stroke of the driving device. The pairwise communication of the four holes on the valve body can be achieved, and the changeover purpose is realized.
Description
Technical field
The utility model relates to a kind of four-way fluid selector valve, particularly relates to a kind of linear type four-way fluid selector valve.
Background technique
At present, known four-way fluid selector valve is to drive spool by motor or pneumatic actuator to rotatablely move in valve body, and four holes that reach on the valve body communicate in twos, realize the commutation purpose.The shortcoming of this selector valve is that the location is inaccurate, and electrical fault is many, and in the moment that starts and stop, torque transmission shaft is bigger, and transmission shaft twists off easily.
Summary of the invention
The purpose of the utility model selector valve has been to overcome the defective of original technology, and the location is reliable, and fault is few.
The technological scheme that the utility model is implemented: a kind of reciprocating linear dynamic formula four-way fluid selector valve, its valve body is the hollow cavity of a four-way, spool is a hollow cylinder, connect with drive unit by link, realize that the linear reciprocating motion of drive unit drives the linear reciprocating motion of spool, thereby realize that four holes on the valve body communicate in twos.
Characteristics of the present utility model be simple in structure, be convenient to processing, accurate positioning, be easy to control.
Description of drawings
When Fig. 1 is the drive unit release, realize that A communicates the structural representation when B communicates with D with C.
Fig. 2 is a drive unit when returning to the home position, realizes that A communicates the structural representation when B communicates with C with D.
Among the figure: 1-valve gap, 2-set screws, 3-sealing gasket, 4-spool, 5-valve body, 6-bolt group, 7-link, 8-bearing pin, 9-end cap, 10-drive unit
Embodiment
Linear type four-way fluid selector valve of the present utility model, it is a cylinder type hollow cavity that described valve body is formed an inside by valve gap 1, valve body 5, end cap 9 by set screws 2, sealing gasket 3, have hole A, hole B, hole C, the hole D that communicates with hollow cavity around it, in the hollow cavity of valve body 5 spool 4 is installed, spool 4 can be divided into two-part with hollow cavity and four holes, spool 4 and link 7 by bolt group 6 be connected, link 7 links to each other with drive unit by bearing pin 8, thereby realize that drive unit 10 drive spools 4 do reciprocating linear motion in valve body 5.
When drive unit 10 reached as shown in Figure 1 the position, the hollow cavity of valve body 5 was divided into two-part by spool 4, and this moment, hole A communicated with hole C, and hole B communicates with hole D; When drive unit returned to the home position, as shown in Figure 2, hole A communicated with hole D, and hole B communicates with hole C.So just can realize the purpose of four-way fluid commutation.
Claims (2)
1, a kind of linear type four-way fluid selector valve.It is made up of valve gap (1), spool (4), valve body (5), link (7), bearing pin (8), end cap (9), drive unit (10).Valve body (5) has four holes (A, B, C, D) that communicate with hollow cavity all around, spool (4) is divided into two-part with hollow cavity and four holes, spool (4) links with drive unit (10) by link (7), bearing pin (8), under the effect of drive unit (10), axis along valve body (5) does reciprocating linear motion, with the stroke location of drive unit (10), four holes that reach on the valve body (5) communicate in twos, realize the purpose of commutation.
