Be equipped with the current limliting bar for extending to main directed cavity, the end of the current limliting bar main lead column be moved to most everywhere when with main lead column phase
Support, described limit chamber is located at limited block top and is provided with the protection spring that limited block resets downwards.
Give valve element vertical stabilization guiding by using above-mentioned technical proposal, main lead column, secondary lead column avoids valve element
Rotate in a circumferential direction, limited block avoids valve element surpassed distance from departing from directed cavity, and tune amount cylinder limits the extreme higher position of main lead column by stretching,
Change maximum stream flow, make check-valves that there is the function of regulation flow, and protect spring then before main lead column contact current limliting bar
Slow down, it is to avoid cause current limliting rod to become, so as to increase the service life.
The utility model is further arranged to：Described closing mouth is provided with the valve seat coordinated with seal spool, the valve seat
Including skeleton and intraskeletal lip ring is installed on, described lip ring top is provided with and extends to closing mouth top
Extension.
On the one hand contacted with the valve element for declining in advance by using the extension of above-mentioned technical proposal, lip ring, risen
To the effect of buffering, on the other hand postpone closing mouth and open, it is to avoid underfed, valve element is closed once again.
The utility model is further arranged to：Described lip ring lower section is provided with and lip ring resets upwards
Buffer spring.
By using above-mentioned technical proposal, buffer spring is set up, buffered when making valve element close to closed mouth, reduce both
Damage caused by shock.
The utility model is further arranged to：Described valve element is provided with going out to flow end towards the end face for going out to flow end medium
The lead-in chamfered that guide spool declines during impact.
By using above-mentioned technical proposal, stop some medium counter flow into going out to flow end after medium at influent stream end,
And lead-in chamfered accelerates closing mouth and seal spool to coordinate, it is to avoid medium counter flow is back into stream end.
The utility model is further described with reference to the accompanying drawings and detailed description.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model specific embodiment；
Fig. 2 is the enlarged drawing of A in Fig. 1.
Specific embodiment
