Description

wear-resistant knife gate valve with high fitting degree

Technical Field

The utility model relates to a wear-resisting knife gate valve technical field especially relates to wear-resisting knife gate valves that agree with degree height.

Background

The valve is a control part in a fluid delivery system, and has functions of stopping, adjusting, guiding, preventing backflow, stabilizing pressure, shunting, overflowing, relieving pressure, and the like, the valve used in the fluid control system is a gate plate, the movement direction of the gate plate is perpendicular to the fluid direction, and the knife gate valve can only be fully opened and fully closed, but cannot be adjusted and throttled, and the valve used in the simplest stop valve to the extremely complex automatic control system has quite a large variety and specifications.

The knife gate valve relies on the draw-in groove that flashboard and valve body bottom set up to agree with mutually to realize the effect of cutting the fluid in the use, and impurity in the fluid can pile up and cause the flashboard to agree with the not tight condition with the draw-in groove that the valve body bottom set up in the draw-in groove in usual use, and this impurity that just needs in to the draw-in groove clears up, but clears up the impurity in the draw-in groove very inconvenient and the degree of difficulty is great.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects in the prior art, for example, the knife gate valve realizes the cut-off action of the fluid by the matching of the flashboard and the clamping groove arranged at the bottom of the valve body in the using process, the impurities in the fluid can be accumulated in the clamping groove in the usual using process to cause the situation that the flashboard is not tightly matched with the clamping groove arranged at the bottom of the valve body, the impurities in the clamping groove need to be cleaned, but the impurities in the clamping groove are very inconvenient to clean and have larger difficulty, and then wear-resistant knife gate valves with high matching degree are provided.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

wear-resisting knife gate valve that degree of agreeing with is high, including valve body, flashboard, support, valve rod, hand wheel, the interior bottom of valve body is provided with the draw-in groove that agrees with mutually with the flashboard, a plurality of recesses have been seted up equidistantly in proper order to the interior bottom of draw-in groove, every all be provided with the dog in the recess, be provided with well cavity in the valve body, every the ventiduct that is linked together with well cavity is all seted up to the interior bottom of recess, every it has the connecting rod, every all to alternate in the ventiduct the lower extreme of connecting rod is connected with the inside wall of well cavity through the spring, the bottom of valve body is provided with.

Preferably, the spring is an extension spring.

Preferably, the upper end of the connecting rod passes through the air outlet channel, extends into the groove and is fixedly connected with the bottom of the stop block.

Preferably, the inflation mechanism comprises an air pipe which is arranged at the bottom of the valve body and communicated with the hollow cavity in the valve body.

Preferably, an air nozzle is installed at the end of the air pipe.

The utility model has the advantages that: pile up behind too much impurity in the draw-in groove that valve body bottom set up, can raise the flashboard, then go into the cavity intracavity with high-pressure gas via the air cock pump with the air pump, high-pressure gas can pass the gas outlet channel like this and give the dog jack-up, a plurality of dogs are by jack-up simultaneously, can be with the interior flaky impurity of bottom bonding of draw-in groove for jack-up tear apart, originally, the flaky impurity layer that bonds is cracked, the clearance work of personnel to the draw-in groove internal impurity that the valve body bottom set up has been made things convenient for, time saving and labor saving, therefore, the clothes hanger is strong.
