Description
Technical field
The utility model is related to a kind of filtering ball-and-seat.
Background technology
To prevent liquid from flowing backwards, ball-and-seat is installed on comb line outside oilfield oil well and contaminated-oil basin.Ball-and-seat one end
For valve seat, it is connected with carrying out liquid pipe line, the other end is circular hole end face, is connected with water outlet pipeline, realizes liquid one way flow
Purpose.But, due to containing impurity, sump oil etc. in liquid, it may appear that valve ball blocks water outlet with valve seat blow-by, impurity dirt
The phenomenons such as hole, cause single current defective valve or water outlet hole plug, lose effect of ball-and-seat.
Utility model content
For above-mentioned situation, to overcome prior art defect, the purpose of the utility model is just to provide a kind of filtering single current
Valve, the problem of valve ball and valve seat blow-by, impurity dirt that can effectively solve ball-and-seat easily block apopore.
The technical scheme that the utility model is solved is, including valve bonnet and valve seat, and valve bonnet is the cavity body of both ends open, valve bonnet
Top in be embedded with yi word pattern baffle plate, valve bonnet and have valve ball, the bottom of valve bonnet and the top spinning of valve seat are tightly connected, valve seat
Top end opening and bottom end opening between connected through passage, the diameter of passage is less than the diameter of valve ball, the bottom of valve seat and filtering
The top spinning of device is tightly connected, and filter is front opening, the tubulose of back-end closure, the perisporium of filter and bottom
On be evenly equipped with gap.
The utility model is simple in construction, easy to use, and valve ball is end face seal with valve seat, seals tight, prevents liquid from falling
Stream, effect is good.
Brief description of the drawings
Fig. 1 is structural profile front view of the present utility model.
Fig. 2 is the structure sectional view of the utility model valve bonnet.
Fig. 3 is the structure sectional view of the utility model valve seat.
Fig. 4 is the structural front view of the utility model filter.
Fig. 5 is the structural front view on the utility model valve bonnet top.
Embodiment
Embodiment of the present utility model is elaborated below in conjunction with accompanying drawing.
Provided by Fig. 1-Fig. 5, the utility model includes valve bonnet and valve seat, valve bonnet 1 is the cavity body of both ends open, valve bonnet
Being embedded with top in yi word pattern baffle plate 3, valve bonnet has valve ball 4, and the bottom of valve bonnet and the top spinning of valve seat 2 are tightly connected, valve
Connected between the top end opening and bottom end opening of seat through passage 5, the diameter of passage is less than the diameter of valve ball, the bottom of valve seat and mistake
Filter device 8 top spinning be tightly connected, filter be front opening, the tubulose of back-end closure, the perisporium of filter and
Gap 6 is evenly equipped with bottom.
Described valve seat 2 is the cavity that both ends open is big, center-aisle is small.
Described gap 6 is strip.
The external diameter of described valve seat 2 is identical with the external diameter of filter, the bottom end opening internal diameter of valve seat 2 and filter
Internal diameter is identical.
The external diameter of described valve bonnet 1 is more than the external diameter of valve seat.
The top of described valve seat 2 is put in the bottom of valve bonnet.
The top end opening and passage of described valve seat 2 are connected through changeover portion 7, and changeover portion is the small taper type in the big bottom in top.
Described yi word pattern baffle plate 3 is placed in the top center of valve bonnet.
Described valve bonnet 1 and valve seat 2 are through the first seal with screwed joint.
Described valve seat 2 and filter is connected through the second thread seal.
Yi word pattern baffle plate is embedded with valve bonnet top of the present utility model, it is in yi word pattern end face to constitute valve bonnet top, can be had
Effect avoids impurity and dirt in liquid from blocking circular hole, causes pipeline to build the pressure.Valve seat and valve bonnet is are threadedly coupled, when carrying out liquid,
Valve ball is lifted off a seat, and liquid flows out from yi word pattern end face, and when liquid flows backwards, liquid floats valve ball, and pushes valve ball to valve seat
At top end opening, valve ball is set to get lodged in the top end opening of valve seat and the junction of passage, so as to block liquid further towards valve
In the passage of seat, it is in end face seal shape to be formed between valve ball and valve seat, so reach the purpose for preventing that liquid from flowing backwards, filter
With valve seat to be threadedly coupled, the body of filter and bottom are designed with gap.The utility model has effectively solved ball-and-seat
The problem of valve ball easily blocks apopore with valve seat blow-by, impurity dirt, there is good economic and social benefit.
