Abstract

The utility model discloses a regulating valve, including valve housing and the circular valve block of setting in valve housing, one side of circular valve block is connected with a torque motor driven pivot of passing valve housing, and the opposite side is connected with one through the loose axle that the bearing set up on valve housing, valve housing is also passed to the other end of loose axle, and fixed being equipped with on the tip hits the key, outside at valve housing, around the loose axle, be equipped with a pair ofly and hit the key complex in the middle of the contained angle for 90 degrees levels hit the piece and hit the piece perpendicularly, the valve housing is outer, the tip and the level that cover the loose axle hit the piece, the level hits the piece, is equipped with the housing. The utility model discloses a governing valve, the structure is ingenious, controls circular valve block through torque motor, hits the level between the epaxial striking of position loose axle and hits the piece or hit the piece perpendicularly and block just not changeing, can reach and open 1 second, close 1 second open or close fast, obtain excellent blowback effect, and the practicality is strong.

Description

Regulating valve

Technical Field

The utility model belongs to the machine parts field especially relates to a governing valve.

Background

On a dust remover, in order to avoid that a filter screen is completely blocked by dust, high-pressure back flushing requirements are usually met, a valve-overlapping actuator is mostly used for opening and closing an existing back flushing device, but the actuator is mostly driven by air pressure or hydraulic pressure, so that the opening and closing processes all need about 30 seconds, namely long time and slow action, and too long time can cause great discount of back flushing force or larger back flushing pressure, so that energy consumption is increased. Therefore, a better way to control the switch of the blowback device needs to be found.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a governing valve is provided.

The utility model discloses a realize through following technical scheme:

the governing valve, including valve housing and the circular valve block of setting in valve housing, one side of circular valve block is connected with a torque motor driven pivot that passes valve housing, and the opposite side is connected with one through the loose axle that the bearing set up on valve housing, the other end of loose axle also passes valve housing, and fixed being equipped with on the tip hits the key, outside at valve housing, around the loose axle, be equipped with a pair ofly and hit the piece perpendicularly for 90 degrees with hitting the horizontal of the middle contained angle of key complex, valve housing is outer, the tip and the level that cover the loose axle hit the piece, the level that hits the piece, is equipped with the housing to guarantee safety.

Preferably, a shaft sleeve is sleeved on the movable shaft, and the bearing is in contact with the shaft sleeve.

Preferably, both sides of the circular valve plate are connected with a rotating shaft and a movable shaft driven by a torque motor through hinged bolts.

Preferably, a speed reducer is further provided between the torque motor and the rotating shaft.

The utility model has the advantages that:

the utility model discloses a governing valve, the structure is ingenious, controls circular valve block through torque motor, hits the level between the epaxial striking of position loose axle and hits the piece or hit the piece perpendicularly and block just not changeing, can reach and open 1 second, close 1 second open or close fast, can realize the blowback effect of pulsed, through opening even twice, can obtain excellent blowback effect, and the practicality is strong, is worth promoting.

Drawings

For ease of illustration, the invention is described in detail by the following specific examples and figures.

Fig. 1 is a schematic view of the structure of the present invention;

fig. 2 is a schematic top view of the present invention;

fig. 3 is a schematic side view of the present invention.

Detailed Description

As shown in fig. 1-3, the regulating valve includes a valve housing 1 and a circular valve plate 2 disposed in the valve housing 1, one side of the circular valve plate 2 is connected to a rotating shaft 4 driven by a torque motor 3 passing through the valve housing 1, the other side is connected to a movable shaft 6 disposed on the valve housing 1 through a bearing 5, the other end of the movable shaft 6 also passes through the valve housing 1, and a striking pin 7 is fixedly disposed on the end portion, a pair of a horizontal striking block 8 and a vertical striking block 9, which are engaged with the striking pin 7 and have a middle included angle of 90 degrees, are disposed outside the valve housing 1 and around the movable shaft 6, and a housing 10 is disposed outside the valve housing 1 and covers the end portion of the movable shaft 6, the horizontal striking block 8 and the horizontal striking block 9 to ensure safety.

The movable shaft 6 is sleeved with a shaft sleeve 11, and the bearing 5 is in contact with the shaft sleeve 6.

And both sides of the circular valve plate 2 are connected with a rotating shaft 4 and a movable shaft 6 which are driven by a torque motor 3 through hinged bolts 12.

And a speed reducer 13 is also arranged between the torque motor 3 and the rotating shaft 4.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
