Abstract
The utility model discloses a self compensation spring sealing device for a transverse moving valve. The self compensation spring sealing device comprises a support sleeve (1), wherein a pressure spring (2) is arranged in the support sleeve (1). The self compensation spring sealing device adopts the technical scheme, and the constant pressure between the sealing surface of a valve plate and a sealing surface of an upper valve body can be maintained for a long time. After the transverse moving valve provided by the utility model is mounted, the phenomenon that the sealing surface of the valve plate cannot be tightly pasted with the sealing surface of the upper valve body after the long-time use cannot be generated. When the mounted transverse moving valve provided by the utility model is used for production, the production cost can be reduced, and the production efficiency is improved.
Description
Technical field
The utility model relates to a kind of self compensation spring seal unit, relates in particular to the self compensation spring seal unit that a kind of shiftable valve is used.
Background technique
In the powder material course of conveying, shiftable valve is one of important device.In the existing shiftable valve, valve plate directly is connected with swing arm.After using certain hour,, reduced the sealing of shiftable valve owing to reasons such as mechanical wear can make sealing surface of valve plate can not fit tightly the upper valve body sealing surface.Thereby producer needs often maintenance replacement shiftable valve, increases cost of production, reduced manufacturing efficiency.
Summary of the invention
The purpose of the utility model is, the self compensation spring seal unit that provides a kind of shiftable valve to use.This self compensation spring seal unit can keep having constant pressure between sealing surface of valve plate and upper valve body sealing surface for a long time.The shiftable valve of this self compensation spring seal unit has been installed, after long-time the use, the phenomenon that sealing surface of valve plate can not fit tightly the upper valve body sealing surface can have not been occurred.Shiftable valve production that this self compensation spring seal unit has been installed in use can reduce production costs, and enhances productivity.
For solving the problems of the technologies described above, the utility model adopts following technological scheme: the self compensation spring seal unit that a kind of shiftable valve is used, comprise carrying sleeve, and be provided with pressure spring in the carrying sleeve.
In the self compensation spring seal unit that aforesaid shiftable valve is used, described pressure spring adopts the heat resisting alloy high-strength spring.
Compared with prior art, the utility model adopts technique scheme, can keep for a long time having constant pressure between sealing surface of valve plate and upper valve body sealing surface.The shiftable valve of the utility model has been installed, after long-time the use, the phenomenon that sealing surface of valve plate can not fit tightly the upper valve body sealing surface can have not been occurred.Shiftable valve production that the utility model has been installed in use can reduce production costs, and enhances productivity.
Description of drawings:
Fig. 1 is the mounting structure schematic representation of the utility model.
Reference character:
The 1-carrying sleeve, 2-pressure spring, 3-valve plate, 4-swing arm, 5-upper valve body.
Below in conjunction with accompanying drawing and embodiment the utility model is further described, but not as the foundation to the utility model restriction.
Embodiment
Embodiment.The self compensation spring seal unit that a kind of shiftable valve is used, as shown in Figure 1, comprise carrying sleeve 1, be provided with pressure spring 2 in the carrying sleeve 1.
During installation, the lower end of carrying sleeve 1 is welded on swing arm 4 one ends, the bottom of valve plate 3 is enclosed within the upper end of carrying sleeve 1.When shiftable valve started, swing arm 4 drove valve plate 3 swings through the self compensation spring seal unit.Pressure spring 2 can keep having constant pressure between valve plate 3 sealing surfaces and upper valve body 5 sealing surfaces for a long time.
Install the shiftable valve of this self compensation spring seal unit, after long-time the use, the phenomenon that sealing surface of valve plate can not fit tightly the upper valve body sealing surface can not occur.Operative installations the shiftable valve of self compensation spring seal unit can reduce production costs, enhance productivity.
In the present embodiment, pressure spring 2 adopts the heat resisting alloy high-strength spring.
Claims (2)
1. the self compensation spring seal unit that shiftable valve is used is characterized in that: comprise carrying sleeve (1), be provided with pressure spring (2) in the carrying sleeve (1).
2. the self compensation spring seal unit that shiftable valve according to claim 1 is used is characterized in that: described pressure spring (2) adopts the heat resisting alloy high-strength spring.
