The utility model is characterized in that: an inlet valve body and an outlet valve body are connected together to form the valve body of the board plug valve; both the inlet valve body and the outlet valve body consist of a flange disc, a valve neck and a base plate, and the two end sections of the base plate are semi-arc rectangular boards; the valve body is provided with a vertical central passage hole, the joint between the inlet valve body and the outlet valve body is provided with a rectangular plug board slot with two semi-arc end sections, and a concave plane arranged on a lower base plate on the inner side of the plug board slot is communicated with the central passage hole; a plug board capable of sliding is arranged in the plug board slot, the plug board is a rectangular board which has a vertical through hole on the right upper part and two semi-arc end sections, elastic brush strips are arranged on the top and bottom surfaces of the circumference of the plug board, a horizontal through hole which has a seal ring and is communicated with the plug board slot is arranged on the right of the joint between the inlet valve body and the outlet valve body, and a driving device hinged with the plug board is arranged on the outside right of the joint between the inlet valve body and the outlet valve body. The utility model can eliminate the phenomenon that the plug board is stuck in bulk material, thereby improving working efficiency.

Description

There is not stifled push-pull valve

Technical field

The utility model belongs to valve, especially relates to a kind of valve of powder bulk cargo.

Background technique

Push-pull valve also claims sluice valve or gate valve, be installed on to play on the discharge port of various powder grain material hoppers or the elephant trunk and open and the shutoff effect, also can control the flow of powder bulk cargo by the size of adjusting valve opening, though existing push-pull valve has possessed good airproof performance, wear-resisting characteristics, but plate often occurs and blocked the phenomenon that to close fully by bulk cargo, the reason that can not close fully is that the inboard of bulk cargo port hole has the plugboard trough for the plate slippage, open passage, in the process of letting out under the bulk cargo, the powder bulk cargo enters in the plugboard trough easily, causes plate to be blocked and can not close and put in place, has a strong impact on the shutoff effect of push-pull valve and to the regulating action of bulk cargo emission flow.

Summary of the invention

The purpose of this utility model is to propose the stifled push-pull valve of a kind of nothing, in the slipping of plate, utilize plate to clear up the bulk cargo that is stuck in the plugboard trough voluntarily, eliminate the phenomenon that plate is blocked by bulk cargo, the size that plate could fully be opened or turn-off port hole and can fully regulate the bulk cargo flow is increased work efficiency.

The purpose of this utility model is achieved like this: a kind of nothing is blocked up push-pull valve, the valve body that it is characterized in that push-pull valve by on the charging valve body put and the discharge valve body and function bolt of underlying be formed by connecting, this charging valve body is made one by upper flange plate, last valve neck and upper plate from top to bottom, on the charging valve body, offer the vertical central channel hole, upper plate is the rectangular slab of semi-circle for the two ends section, and the periphery of upper plate has had the convex shoulder of screw uniform; This discharging valve body is from bottom to top by lower flange, following valve neck and lower shoe are made one, on the discharging valve body, offer the vertical central channel hole, lower shoe is the rectangular slab of semi-circle for the two ends section, the periphery of lower shoe has had the convex shoulder of screw uniform, in addition, be positioned at the connecting part of charging valve body and discharging valve body, offering the two ends section on charging valve body and discharging valve body is the rectangular plugboard trough of semi-circle, this plugboard trough can be opened in respectively on upper plate and the lower shoe symmetrically, also can be opened in individually on the lower shoe, distance between at the bottom of the front and back side channel of plugboard trough is identical with the external diameter of valve neck, be positioned at the inboard of plugboard trough periphery, on lower shoe, offer the conocave plane that communicates with the central passage hole; In addition, sliding dress plate in plugboard trough, plate also is that the two ends section is the rectangular slab of semi-circle, the length of plate is two times of valve neck external diameter, width between the front and back side of plate is less than the distance between the bottom land before and after the plugboard trough, elasticity brush bar is installed on the top and bottom of plate periphery, on the right-hand part of plate, is offered vertical through holes; In addition, when plugboard trough is opened on upper plate and the lower shoe symmetrically respectively, offer the horizontal through hole that communicates with plugboard trough of band seal ring on the right side of the connecting part of charging valve body and discharging valve body, drive unit is installed in the right outside in the connecting part of charging valve body and discharging valve body, when plugboard trough is opened on the lower shoe individually, offer the horizontal through hole that communicates with plugboard trough of band seal ring on the right side of lower shoe, drive unit is installed in the right outside at lower shoe, this drive unit be bolt and nut when secondary then the left side section of screw rod stretch in the horizontal through hole and be hinged and connected with plate, when this drive unit was cylinder or oil hydraulic cylinder, then the left side section of piston rod stretched in the horizontal through hole and is hinged and connected with plate.

During use, this push-pull valve relies on upper flange plate and lower flange to be mounted on the discharge port or elephant trunk of hopper, when manual electronic or pneumatic or surge correspondingly start drive unit after, promote plate right-to-left translation in plugboard trough, when progressively connecting from small to large between the central passage hole on vertical through holes on the plate and the push-pull valve valve body, just can regulate the flow of bulk cargo as required until the flow maximum, when plate when translation makes the blind plate district of the left side of plate be in the central passage hole of push-pull valve valve body from left to right, just turn-offed the following of bulk cargo and let out; Because in the plate translation process, when especially passing through energy bulk cargo whereabouts in the central passage hole, plate is arranged in plugboard trough always, add the elasticity brush bar on the plate peripheric surface, intercepted bulk cargo well and entered in the plugboard trough,, also in plate translation process, taken out of voluntarily even there is a small amount of bulk cargo to enter in the plugboard trough, thereby eliminated plate effectively by the phenomenon that the bulk cargo card blocks up, improved working efficiency.

The nothing that the utility model proposes is blocked up push-pull valve, and is rational in infrastructure, safe and reliable, eliminates the phenomenon that plate is blocked by bulk cargo, and the size that plate could fully be opened or turn-off port hole and can fully regulate the bulk cargo flow is increased work efficiency.
