Abstract
The utility model discloses a kind of split type Proportional valve, comprises valve body and filter screen, it is characterized in that: valve body is split-type structural, and is made up of upper valve body and lower valve body; The center hole top of upper valve body is external connector linkage section, is embedded with one piece of filter screen in the middle part of the center hole of upper valve body; The center hole of lower valve body 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; Instantly, when the bottom of upper valve body center hole is inserted on valve body top, insertion part is connected with the lower thread of upper valve body center hole, and the center hole of upper and lower valve body is on same straight line.The utility model is split-type structural, when needed upper and lower valve body can be taken apart, and then the filter screen in cleaning upper valve body center hole, 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.
Description
Technical field
The utility model belongs to valve field, specifically, particularly relates to a kind of split type 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 split type Proportional valve that can facilitate cleaned filter screen.
The technical solution of the utility model is as follows: a kind of split type 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); The center hole top of described upper valve body (1a) is external connector linkage section, is embedded with one piece of described filter screen (2) in the middle part of the center hole of this upper valve body; 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; When the bottom of upper valve body (1a) center hole is inserted on described lower valve body (1b) top, this insertion part is connected with the lower thread of upper valve body (1a) center hole, and 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 the filter screen (2) in cleaning upper valve body (1a) center hole, 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.
Adopt above technological scheme, the utility model is split-type structural, when needed upper and lower valve body can be taken apart, and then the filter screen in cleaning upper valve body center hole, 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, 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.
For the ease of manufacturing, and have cost consideration concurrently, described upper valve body (1a) and lower valve body (1b) are working of plastics.
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 the filter screen in cleaning upper valve body center hole, 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.

Embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
As shown in Figure 2, a kind of split type 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 the external diameter of upper valve body 1a and lower valve body 1b is equal, and is 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, and is embedded with one piece of filter screen 2 in the middle part of the center hole of upper valve body 1a.
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, the 1/6-1/4 of Shi great footpath, the aperture section of this restricted section.The large footpath section of described lower valve body 1b center hole bottom is external connector linkage section, and this external connector linkage section is internal thread segment, and the external connector linkage section aperture of lower valve body 1b equals the aperture of upper valve body 1a external connector linkage section.Be set with a seal ring 3 in the circular groove of described lower valve body 1b periphery upper end portion, the periphery of sealing circle 3 can with the hole wall close contact of upper valve body 1a center hole.When the bottom of upper valve body 1a center hole is inserted on described lower valve body 1b top, this insertion part is connected with the lower thread of upper valve body 1a center hole, the periphery of seal ring 3 can with the hole wall close contact of upper valve body 1a center hole, and the center hole of upper valve body 1a and lower valve body 1b is on same straight line, thus upper valve body 1a and lower valve body 1b is linked together, form complete valve body 1.
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.
