Abstract
The utility model relates to a kind of pneumatic discharging valve, comprise valve body, in valve body, valve rod is installed, valve body import is provided with valve seat, and valve rod one end is provided with spool through after valve seat, is provided with filler cover above valve body, the valve rod the other end is connected with pneumatic actuator through after filler cover, be filled with filler between described filler cover and valve rod, filler set upper side is fixed with the Gland be set in outside valve rod, is provided with Compress Spring between filler and Gland.The utility model is provided with Compress Spring above filler; the Gland be fixedly connected with filler cover is installed above Compress Spring; Gland compresses Compress Spring; if filler weares and teares; spring will extend and automatically filler be compressed again; filler place would not leak, without frequent shutdown maintenance, very easy to use.
Description
Technical field
The utility model relates to a kind of valve, is specifically related to a kind of pneumatic discharging valve.
Background technique
Filler in the valve of current discharging valve is all directly push down with Gland, if filler place leaks, manually Gland is compressed again, such situation often occurs, and needs frequent shutdown maintenance, bothers very much.Pneumatic actuator is indirectly arranged on filler by support and puts in addition, and this structure, with support, when not only having taken material but also taken a lot of work, increased cost.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of pneumatic discharging valve, and be provided with holddown spring between its Gland and filler, it compresses filler automatically, and filler place can not leak.
For achieving the above object, the technological scheme that the utility model is taked is:
A kind of pneumatic discharging valve, comprise valve body, in valve body, valve rod is installed, valve body import is provided with valve seat, and valve rod one end is provided with spool through after valve seat, is provided with filler cover above valve body, the valve rod the other end is connected with pneumatic actuator through after filler cover, be filled with filler between described filler cover and valve rod, filler set upper side is fixed with the Gland be set in outside valve rod, is provided with Compress Spring between filler and Gland.
Described pneumatic actuator is fixed on filler and puts.
First seal ring is installed between described filler and Compress Spring.
Also be provided with the second seal ring between described filler cover and valve rod, the second seal ring is arranged on below filler.
Described Gland is bolted on filler and puts.
The utility model is provided with Compress Spring above filler; the Gland be fixedly connected with filler cover is installed above Compress Spring; Gland compresses Compress Spring; if filler weares and teares; spring will compress filler automatically again; filler place would not leak, without frequent shutdown maintenance, very easy to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of pneumatic discharging valve, comprise valve body 1, in valve body 1, valve rod 2 is installed, valve body import is provided with valve seat 3, valve rod 2 one end is provided with spool 4 through after valve seat 3, filler cover 5 is provided with above valve body 1, valve rod 2 the other end is connected with pneumatic actuator 6 through after filler cover 5, filler 7 is filled with between described filler cover 5 and valve rod 2, filler overlaps 5 upper ends and is fixed with the Gland 9 be set in outside valve rod, Compress Spring 8 is installed between filler 7 and Gland 9, if filler weares and teares, spring will extend and automatically filler be compressed again, filler place would not leak, keep in repair without frequent shutdown, very easy to use.
Pneumatic actuator 6 of the present utility model is fixed on filler cover 5, eliminates support, significantly reduces cost, improve the economic benefit of enterprise.First seal ring 10 is installed between filler 7 and Compress Spring 8.Also be provided with the second seal ring 11, second seal ring 11 between filler cover 5 and valve rod to be arranged on below filler 7.Gland 9 is bolted on filler cover 5.
During the utility model specific works, pneumatic actuator 6 is with ovable valve stem 2 to do upper and lower motion, and valve rod 2 is with movable valve plug 4 and valve seat 3 to open conjunction, and then realizes the opening and closing of pneumatic discharging valve.
