Description
Technical field
The utility model belongs to valve field, specifically, particularly relates to a kind of Proportional valve.
Background technique
As described in Figure 1, traditional Proportional valve is monolithic construction, and be made up of valve body 1 and filter screen 2, wherein valve body 1 center hole is the 3 stops shoulder hole of being small at both ends and big in the middle, wherein central diameter section is restricted section, and the large footpath section of upper and lower part is external connector linkage section, and the large footpath section on top is installed with one piece of described filter screen 2.
Because the restricted section aperture of valve body 1 is minimum, very easily block, the time has been grown filter screen and will pollute gradually, block, and conventional proportional valve is monolithic construction, so just cannot cleaned filter screen, and then can only scrap Proportional valve, so unavoidably according to one-tenth waste.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of Proportional valve that can facilitate cleaned filter screen.
The technical solution of the utility model is as follows: a kind of Proportional valve, comprise valve body (1) and filter screen (2), it is characterized in that: described valve body (1) is split-type structural, and be made up of upper valve body (1a) and lower valve body (1b), these two parts are working of plastics; The center hole top of described upper valve body (1a) is external connector linkage section, and the center hole underpart of this upper valve body is provided with an annular stop boss (1c); The center hole of described lower valve body (1b) is the two-part shoulder hole of being small at both ends and big in the middle, its central diameter section is restricted section, the large footpath section of its underpart is external connector linkage section, and the top of lower valve body (1b) periphery has an annular stop draw-in groove;
When the bottom of upper valve body (1a) center hole is inserted on described lower valve body (1b) top, described filter screen (2) is contained in the center hole of upper valve body (1a), and be clamped between the step surface of this center hole and the upper-end surface of lower valve body (1b), and the annular stop boss (1c) of upper valve body (1a) center hole snaps in the annular stop draw-in groove on lower valve body (1b) top, the center hole of upper and lower valve body (1a, 1b) is on same straight line.
In technique scheme, upper valve body (1a) and lower valve body (1b) can be taken apart in use a period of time by user, thus first filter screen (2) is taken out in upper valve body (1a), cleaned filter screen (2) again, easy to clean, so just can ensure the normal use of filter screen (2), can avoid again scrapping the defect of whole Proportional valve because filter screen (2) cannot use as before, thus reach the object reduced costs.Further, upper valve body (1a) and lower valve body (1b) are working of plastics, and adopt snap fit to coordinate, and can ensure that connection is firm like this, be convenient to again dismounting.
Adopt above technological scheme, the utility model is split-type structural, can be taken apart by upper and lower valve body when needed, and then cleaning after being taken out by filter screen, easy to clean is quick, time saving and energy saving, so just can ensure the normal use of filter screen, the defect of scrapping whole Proportional valve as before because filter screen cannot use can be avoided again, thus reach the object reduced costs, and structure of the present utility model is simple, easy to implement, there is good practicability.
In order to improve sealing effect, in the circular groove of described lower valve body (1b) periphery upper end portion, be set with a seal ring (3), the periphery of sealing circle can with the hole wall close contact of described upper valve body (1a) center hole.
As preferably, the external connector linkage section of described upper valve body (1a) and lower valve body (1b) center hole is internal thread segment, and the external diameter of upper valve body (1a) is equal with the external diameter of lower valve body (1b) bottom.
Adopt above structure, external connector linkage section is internal thread segment and facilitates like this and be connected with external connector, certainly also can adopt the external connector linkage section of other structural types.In addition, the external diameter of upper valve body (1a) is equal, so not only goodlooking with the external diameter of lower valve body (1b) bottom, and is convenient to mounting arrangements.
Beneficial effect: the utility model is split-type structural, when needed upper and lower valve body can be taken apart, and then cleaning after filter screen is taken out, easy to clean is quick, time saving and energy saving, so just can ensure the normal use of filter screen, the defect of scrapping whole Proportional valve as before because filter screen cannot use can be avoided again, thus reach the object reduced costs, and structure of the present utility model is simple, easy to implement, good airproof performance, goodlooking, there is good practicability, and be convenient to install and arrange.
Accompanying drawing explanation
Fig. 1 is the structural representation of conventional proportional valve;
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 2, a kind of Proportional valve, is made up of valve body 1, filter screen 2 and seal ring 3.Wherein, valve body 1 is split-type structural, and is made up of upper valve body 1a and lower valve body 1b, and these two parts are working of plastics.The center hole top of described upper valve body 1a is external connector linkage section, and this external connector linkage section is internal thread segment.The center hole underpart of upper valve body 1a is provided with an annular stop boss 1c, the internal surface of this annular stop boss 1c to be gradient the be inclined-plane of 30 °-60 °, the upper end on this inclined-plane is near the shaft axis of upper valve body 1a, the lower end on this inclined-plane, away from the shaft axis of upper valve body 1a, facilitates and the annular stop draw-in groove snap-fit engagement on lower valve body 1b like this.
The center hole of described lower valve body 1b is the two-part shoulder hole of being small at both ends and big in the middle, and its central diameter section is restricted section, and the large footpath section of its underpart is external connector linkage section, and this external connector linkage section is internal thread segment.The external diameter on lower valve body 1b top is less than the external diameter of its underpart, and the top of this lower valve body 1b periphery has an annular stop draw-in groove, and the external diameter of lower valve body 1b bottom equals the external diameter of upper valve body 1a.Be set with a seal ring 3 in the circular groove of described lower valve body 1b periphery upper end portion, sealing circle 3 is positioned at above annular stop draw-in groove, and the periphery of seal ring 3 can with the hole wall close contact of described upper valve body 1a center hole.
Instantly before the bottom of upper valve body 1a center hole is inserted on valve body 1b top, first described filter screen 2 is contained in the center hole of upper valve body 1a, and be clamped between the step surface of this center hole and the upper-end surface of lower valve body 1b, and the annular stop boss 1c of upper valve body 1a center hole snaps in the annular stop draw-in groove on lower valve body 1b top, upper valve body 1a and lower valve body 1b, on same straight line, is so just mounted to a complete valve body 1 by the center hole of upper valve body 1a and lower valve body 1b.
The foregoing is only preferred embodiment of the present utility model; it is not restriction with the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
