Abstract
The utility model discloses a tape spool holds split type stop valve of Y type, it includes valve body (1), install in valve body (1) by valve head (2), steel ball (3) and open the valve rod sub -assembly of valve rod (4) that have the guide way constituteing, the seat (5) that packs is installed to valve rod (4) periphery, pack (6) and gland (7), install support (16) on valve body (1), thrust bearing (17) are installed on support (16) upper portion, valve -stem nut (18) and thrust bearing gasket (19), install yoke piece bush (20) on thrust bearing gasket (19), socket cap holding screw (12) and the 2nd stop screw (13) are installed in support (16) outside. The utility model has the advantages of reasonable design, the leakproofness is good, and the security performance is high, valve rod and valve -stem nut small friction, and valve rod and the power that the only existence of packing promoted feel light, convenient operation, the length is used to the life -span of packing.
Description
Technical field
This utility model relates to a kind of valve, is specifically related to the band bearing Y type separate type check valve of a kind of structure excellent in design.
Background technology
Split type Y-shaped cut-off valve of the prior art, stop valve support is provided with valve rod and nut, and hands is passed through in the keying of valve
Take turns direct rotation valve rod to carry out promoting and decline to realize, in this process, be in dry between valve rod and the screw thread of valve stem nut
Friction and valve rod rub with filler rotation, lifting, cause feel the heaviest, and because filler and valve rod spin friction and lifting rub
And causing filler serious wear, valve packing life cycle is short, the property revealed is high.
Therefore, necessary on the basis of prior art, a kind of reasonable in design of design research and development, sealing is high, safety
Property high, during rotation, feel is light, and filler abrasion is few, is difficult to leakage, service life length band bearing Y type separate type check valve.
Summary of the invention
Goal of the invention: the purpose of this utility model is for the deficiencies in the prior art, R & D design one reasonable in design is close
Feng Xinggao, safety is high, and during rotation, feel is light, and filler abrasion is few, is difficult to leakage, service life length band bearing Y type split
Formula stop valve.
Technical scheme: in order to realize object above, the technical scheme that this utility model is taked is as follows:
A kind of band bearing Y type separate type check valve, it includes: valve body, and be arranged in valve body is led by valve head, steel ball and having
The valve rod group component formed to the valve rod of groove, stem outer circumference is provided with filler seat, filler seat is provided with filler, and filler is installed
There is gland, gland is provided with gland, connect fixing by stud and hex nut between gland and valve body；
Being provided with support on valve body, frame upper is provided with needle roller thrust bearing, and needle roller thrust bearing is provided with valve stem nut,
Valve stem nut is arranged on periphery, valve rod upper end, and valve stem nut is arranged above needle roller thrust bearing pad, needle roller thrust bearing pad
On york piece lining is installed, the first limit screw is installed between york piece lining and support, at stent outer, socket cap is installed tight
Determine screw and the second limit screw；Valve stem nut is arranged above handwheel and circlip for shaft.
Preferably, above-described band bearing Y type separate type check valve, install between described stud and hex nut
There is spring washer.
Preferably, above-described band bearing Y type separate type check valve, second described limit screw one end is positioned at valve
In the gathering sill of bar.
Beneficial effect: compared to the prior art the band bearing Y type separate type check valve that this utility model provides has the advantage that
The band bearing Y type separate type check valve that this utility model provides, reasonable in design, good airproof performance, security performance is high.
The keying of valve, handwheel is promoted by rotation valve rod nut and declines valve rod, during this, valve rod and valve stem nut friction
Power is little, and valve rod and filler only exist the power of lifting, and feel is light, and because being only an up friction, the filler life-span uses longer, separately
It is milled with gathering sill on outer valve rod, uses limit screw to be controlled, thus can realize promoting without spin, easy to operate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the band bearing Y type separate type check valve that this utility model provides.
Detailed description of the invention
