Abstract
The utility model provides a bearing rotary valve, mainly comprising a valve cover (1), a valve rod (2) and a valve body (3). The bearing rotary valve is characterized in that the outlet passageway of the inner cavity of the valve body is provided with a stiffening rib (10); a rubber bearing sleeve (4) is arranged between the stiffening rib (10) and the valve rod (2), and the rubber bearing sleeve is squeezed and connected with the stiffening rib and the valve rod; the inner part of the rubber bearing sleeve is provided with a plurality of needle rollers (5); when a handle makes the motion of the opening and closing, the valve rod and the rubber bearing sleeve are driven to rotate; the handle does just need to be rotated 220 DEG, and medium can pass through. Because the rubber bearing sleeve is used to replace a screw rod and a screw nut, a large quantity of the copper materials are saved, the product cost is reduced, and the processing technology is simplified. The utility model has the advantages of tight sealing, drip prevention and leakage prevention.
Description
The utility model relates to a kind of industrial and civilian valve.
At present the valve of installing use at construction industry and hot-water heating pipeline is screw rod, nut type structure, just can open passage after needing during the open and close valve screw rod and nut rotated several 360 °, because sectional area is less than the sectional area of passage in the valve pocket, therefore the medium circulating resistance is big, and step-down is big, valve pocket internal structure complexity, cause processing difficulties, but also the high copper material of call for bids lattice is made element, and cost is short high working life, is prone to and emits, leaks, drips phenomenon.
The purpose of this utility model provide a kind of reasonable in design, simple in structure, be easy to processing and low value, durable, reliable sealing novel bearing stopcock.
The utility model is realized by following measure:
The bearing stopcock mainly is to be made of valve gap (1), valve body (3) and valve rod (2), be provided with stiffening rib (10) at body cavity outlet passage place, in also being provided with, valve body (3) inner chamber adorns the rubber axis bearing sleeve (4) of a plurality of needle rollers (5), this bearing housing is positioned between stiffening rib (10) and the valve rod (2), and be connected with the extruding of stiffening rib and valve rod, the wall thickness of rubber axis bearing sleeve (4) is 3.5-5
, stiffening rib (10) and rubber axis bearing sleeve (4) in vertical state, the thickness of stiffening rib (10) is 3-6
, the needle roller (5) in the rubber axis bearing sleeve (4) adopts metallic material or plastic materials to manufacture.
Description of drawings:
Fig. 1 is that master of the present utility model looks half sectional view;
Fig. 2 is a plan view of the present utility model;
Fig. 3 is that A-A of the present utility model is to sectional view.
Among the figure:
1 valve gap, 2 valve rods, 3 valve bodies
4 bearing housings, 5 needle rollers, 6 grips
7 packing rings, 8 nuts, 9 handles
10 stiffening ribs, 11 sealing gaskets, 12 sealing gaskets
Below in conjunction with accompanying drawing the utility model is further described:
The bearing stopcock mainly is to be made of the valve gap of metallic material system (1), valve rod (2) and valve body (3), and being provided with two thickness at body cavity outlet passage place is 3-6
Stiffening rib (10), and stiffening rib rubber axis bearing sleeve (4) in vertical state places between stiffening rib and the valve rod, and extruding is connected with valve rod with stiffening rib, the wall thickness of rubber axis bearing sleeve is 3.5-5
In the rubber axis bearing sleeve, be provided with the needle roller (5) of 4-6 metallic material or plastic materials system, the valve body top is provided with the handle (9) of a metallic material system, grip (6) places one on handle, and handle is fastening with valve rod by nut (8) and packing ring (7), and valve gap is fixed on the upper end of valve body, sealing gasket (11) places valve gap and valve body connecting position place, sealing gasket (12) places valve rod and valve gap contact position, and valve interior wall is smooth round type, to reach the tight sealing and the effect that reduces wear.
When needs are opened the bearing stopcock, hold handle (9) earlier and rotate 220 °, at this moment valve rod (2) and rubber axis bearing sleeve (4) rotate with it synchronously, and the valve outlet passage is opened, and medium is just negotiable.
The utility model has the advantages that reasonable in design, simple in structure, valve rod adopts the rubber axis bearing sleeve to substitute the bolt and nut structure, therefore simplified processing technology, not only save a large amount of copper materials but also can reduce product cost, when screwing valve, only need about 220 ° of turning handles, medium is just unimpeded not to reduce pressure, and rubber axis bearing sleeve quality softness, sealing be reliable, rotate and open, and closes and do not wear and tear, can not occur dripping, emit, leak phenomenon.
Claims (4)
1, a kind of bearing stopcock mainly is to be made of valve gap (1), valve rod (2) and valve body (3), it is characterized in that valve body (3) inner chamber outlet passage place is provided with stiffening rib (10), the rubber axis bearing sleeve (4) of dress needle roller (5) in valve body (3), also being provided with, this bearing housing (4) is positioned between stiffening rib (10) and the valve rod (2), and extruding is connected with valve rod (2) with stiffening rib (10).
3, bearing stopcock as claimed in claim 1, the wall thickness that it is characterized in that rubber axis bearing sleeve (4) is 3.5-5
