Description
Technical field
The utility model belongs to pipeline valve field, the more particularly to good cage type single seat tune of a kind of non-internal leakage, using effect
Save valve.
Background technology
Regulating valve is very common in pipeline, and leakproofness is very important a, sealing performance pair in regulating valve
The use of regulating valve has a great influence, and our company is twined in a kind of cage type single seat regulating valve of published application in 2011 by adding
Sealing performance is greatly improved around pad, sealing performance is enhanced although changing in this way, is still found that certain in actual use
A little insufficient, the wound gasket of different manufacturers or unlike material, decrement cannot control well, and sealing performance wants decrement
Seeking Truth is point-device, so sealing performance or unstable, can not be precisely controlled, while it is also possible to leakage in occurring, right
Regulating valve normal use affects, and use is very inconvenient.
The technical problem to be solved by the present invention is to provide a kind of good seal performance, decrement controls precisely, is not easy to send out
The novel cage type single seat regulating valve leaked in raw.
Utility model content
For the above-mentioned prior art sealing performance of solution is bad, decrement control is not accurate, interior leakage easily occurs, inconvenient to use
The problems such as, the utility model adopts the following technical solution：
The utility model provides a kind of cage type single seat regulating valve, including valve body, valve deck, caged sleeve, valve rod and valve plug, institute
It states valve deck and is fixedly connected and be arranged at body top axle center, packing spring is equipped in the valve deck, first is equipped in the valve body
Chamber and second chamber, cage-like sleeve are set in valve body and between first chamber and second chamber, cage-like set
Cylinder is equipped with the through-hole of connection first chamber and second chamber, and the valve rod is set at the internal axis of valve body, and the valve plug connects
Connect to be arranged and move in valve stem end and with valve rod, cage-like sleeve bottom offer Z-shaped mouth and with valve body contact face light
Cleanliness is more than 0.8.
The beneficial effects of the utility model are：Sleeve bottom opens up Z-shaped mouth and cancels traditional wound gasket, greatly reduces
Sleeve and valve body contact area, contact surface is highly polished, and decrement control is accurate, and good seal performance is not susceptible to interior leakage, uses
It is convenient.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of embodiment of the utility model.
Fig. 2 is the close-up schematic view of Z-shaped mouth in the utility model.
Specific implementation mode
The preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings.
Referring to Fig. 1, a kind of cage type single seat regulating valve, including valve body 1, valve deck 2, caged sleeve 3, valve rod 4 and valve plug 5,
The valve deck 2, which is fixedly connected, to be arranged at 1 top axle center of valve body, is equipped with packing spring 21 in the valve deck 2, in the valve body 1
Equipped with first chamber 11 and second chamber 12, cage-like sleeve 3 is set in valve body 1 and is located at first chamber 11 and second chamber
Between 12, cage-like sleeve 3 is equipped with the through-hole of connection first chamber 11 and second chamber 12, and the valve rod 4 is set to valve body 1
Internal axis at, the connection of the valve plug 5, which is arranged, to be moved in 4 end of valve rod and with valve rod 4,3 bottom of cage-like sleeve
Offer Z-shaped mouth 31（As shown in Figure 2）And it is more than 0.8 with valve body contact face finish, in this way by opening up Z-shaped in sleeve bottom
Mouth simultaneously cancels traditional wound gasket, greatly reduces sleeve and valve body contact area, and contact surface is highly polished, decrement control essence
Standard, good seal performance are not susceptible to interior leakage, easy to use.
The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field
The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
