Abstract

The utility model discloses an exhaust valve of a rotary drum which is convenient to exhaust and good in exhaust effect. The exhaust valve of the rotary drum comprises a valve body, a valve rod and a valve cover, wherein the valve rod is arranged inside the valve body by virtue of a valve rod rack and matched with a spring; the spring provides downward elastic restoring force to the valve rod; a valve cover is arranged at the upper end of the valve rod; the valve cover is matched with an air outlet of the valve body; a convex rod is arranged at the lower end of the valve rod; a horizontally axial rotating shaft is arranged at the lower end of the valve body; a cam and a hammer handle are arranged on the rotating shaft; the cam and the hammer handle are fixed around the rotating shaft and can coaxially rotate along with the rotating shaft; the cam is matched with the convex rod, and the cam and the spring drive the convex rod to move up and down in a reciprocating manner.

Description

The rotary drum outlet valve

Technical field

The utility model relates to a kind of rotary drum outlet valve, relates in particular to the outlet valve of rotary drum in the leather processing procedure.

Background technique

The exhaust of existing rotary drum operates by the mode of artificial timing exhaust substantially, this method for exhausting need to stop work rotary drum and just can carry out safety and inflate, operating process is wasted time and energy, work efficiency is reduced greatly, and the pressure exhaust valve that is similar to the pressure kettle air valve type is housed on some rotary drum, only have pressure to reach certain value and just carry out exhaust, exhaust effect is undesirable equally, and has the suddenly potential safety hazard of ejection.

Summary of the invention

But technical problem to be solved in the utility model provides the rotary drum outlet valve of a kind of easy to exhaust, good exhaust effect.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of rotary drum outlet valve, comprise valve body, valve rod and valve gap, described valve rod is installed in the valve body and with spring by the valve rod frame and matches, described spring provides valve rod elasticity downward elastic-restoring force, the valve rod upper end is provided with valve gap, described valve gap matches with the air outlet of valve body, the valve rod lower end is provided with nose bar, described valve body lower end is provided with the rotating shaft of horizontal axis, and described rotating shaft is provided with cam and hammer handle spare, and described cam and hammer handle spare are fixed on to be gone up and around the shaft with the rotating shaft coaxial rotation, cam matches with nose bar, and cam and spring drive nose bar and pump.

The beneficial effects of the utility model are: because in the technique scheme, be fixed with cam and hammer handle spare in the rotating shaft of valve body, the rotary drum outlet valve is installed on the rotary drum by screw, the rotating shaft of rotary drum outlet valve and rotary drum around rotatingshaft parallel, along with rotary drum spins upside down, the rotary drum outlet valve also and then rotates up and down, and hammer handle spare is incited somebody to action always vertical lower under action of gravitation in rotation process, namely be equivalent to the cam rotation that hammer handle spare rotates around the axis and drives coaxial rotation, thereby the cam driven nose bar is pumped, namely be with ovable valve stem and valve gap to pump, the air outlet of valve gap and valve body is intermittently left and intermittently exhaust of closed realization in this process.

The utility model will be further described below in conjunction with the drawings and specific embodiments.

Embodiment

Such as Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, a kind of rotary drum outlet valve that the utility model provides, comprise valve body 1, valve rod 2 and valve gap 3, described valve rod 2 is installed in the valve body 1 and with spring 4 by valve rod frame 2-1 and matches, described spring 4 provides valve rod 2 elasticity downward elastic-restoring force, valve rod 2 upper ends are provided with valve gap 3, described valve gap 3 matches with the air outlet of valve body 1, valve rod 2 lower ends are provided with nose bar 2-2, described valve body 1 lower end is provided with the rotating shaft 5 of horizontal axis, described rotating shaft 5 is provided with cam 6 and hammer handle spare 7, described cam 6 and hammer handle spare 7 are fixed in the rotating shaft 5 and with rotating shaft 5 coaxial rotation, cam 6 matches with nose bar 2-2, cam 6 and spring 4 drive nose bar 2-2 and pump, concrete working procedure is, the rotary drum outlet valve is installed on the rotary drum by screw, and overturn with rotary drum, in the process of upset, when the rotary drum outlet valve goes to the above position of rotation axis of rotary drum, the rotary drum outlet valve is exchanged up and down the initial position, two ends up and down, and hammer handle spare 7 under Action of Gravity Field still down, be that the 7 drive rotating shafts 5 of hammer handle spare are rotated relative to valve body 1 with cam 6, so that cam 6 matches with nose bar 2-2, and nose bar 2-2 is moved towards valve gap 3 directions, thereby driving valve gap 3 breaks away from and the cooperating of the air outlet of valve body 1, gas in the valve body 1 is discharged from the air outlet, when the rotary drum outlet valve goes to topmost, relief opening reaches maximum, and the rotation axis that rotary drum outlet valve forwards rotary drum to is during with upper/lower positions, cam 6 no longer provides the active force of nose bar 2-2 towards valve gap 3 directions, this moment, nose bar 2-2 replied towards the direction away from valve gap 3 under the effect of elasticity 4, and drive valve gap 3 matches with relief opening again, finally reach the effect of gap exhaust, but therefore this rotary drum outlet valve has easy to exhaust, the characteristics of good exhaust effect.
