Abstract

The utility model relates to a single plate wear resistance gate valve used for the conveyance pipelines of two-phase flow of the mixing of liquid and solid and other devices. The main characteristic of the utility model is that the utility model comprises a gate plate. The lining of the surface of the gate plate corresponding to the two-phase flow is provided with wear resistance rubber or engineering plastic. The other surface of the gate plate is provided with two inclined blocks matched with two reinforcing plates with inclined surfaces on a valve body. The gate plate and a screw rod are connected by a through pin. The utility model also has other characteristics. Thus the utility model has the advantages of long service life, uniform stress on the gate plate and convenient operation and other advantages and can avoid the disconnection accidents of the gate plate of the common gate plate.

Description

Single plate wear resistance gate valve

The utility model relates to a kind of conveyance conduit of liquid, solid mixing two phase flow or one-board wear-resistant sluice valve of other device of being used for.

Past, at the conveyance conduit of various operations such as industrial and agricultural production, sewage treatment, training of river channel and the cleaning of reservoir silt particle or the common gate valve of other device use, exist the overcurrent position under liquid, solid mixing two phase flow, particularly wherein the bump of solid particle, constantly be worn, the sealing of flashboard and valve body was lost efficacy and the generation leakage easily, poor reliability, service time is short, in addition, also have problems such as flashboard comes off easily.

The purpose of this utility model be to overcome the above-mentioned deficiency of prior art and provide that a kind of overcurrent position is wear-resistant, few, the light labour-saving of operation of service time length, reliable in structure, fault is used for the conveyance conduit of liquid, solid mixing two phase flow or the one-board gate valve of other devices.

The utility model reaches by following approach: the utility model mainly is made up of parts such as valve body, flashboard and handwheels, the surface lining of flashboard is used screw bolt reinforcing again with resilient high-abrasive material (as abrasive rubber or engineering plastics), flashboard connects with screw rod with wearing pin, there is a handwheel on the top of screw rod, there are two skewbacks on the opposite side surface of flashboard, match with two inclined-plane gussets on the valve body, outside dimensions of the present utility model is identical with original gate valve, and it is convenient to change.

Compared with prior art, the utlity model has following advantage:

1, the overcurrent position has served as a contrast resilient high-abrasive material, good seal performance, and service time is long.

2, screw rod and flashboard adopt and wear pin and connects, can avoid the flashboard case accident of the normal appearance of prior art.

3, sealing surface is stressed evenly, operates light laborsaving.

4, outside dimensions and original gate valve is identical, and it is convenient to change.

The drawing explanation:

Fig. 1 is a plan view of the present utility model.

Fig. 2 is a side view of the present utility model.

Fig. 3 is a B-B view of the present utility model.

Fig. 4 is that D of the present utility model is to view.

The utility model describes in detail below with reference to the embodiment in the accompanying drawing, and as shown in drawings, the utility model mainly is made up of parts such as valve body 5, flashboard 2, handwheel 6, screw rod 1, handwheels 6.Flashboard (2) serves as a contrast with high-abrasive materials such as abrasive rubber or engineering plastics with a relative side of liquid, solid mixing two phase flow, opposite side has two skewbacks (3), skewback (3) cooperates with two inclined-plane gussets on the valve body (5), the upper end of flashboard (2) and screw rod (1) connect with wearing pin (4), and there is handwheel (6) on the top of screw rod (1).Outside dimensions of the present utility model is identical with the outside dimensions of original gate valve, and it is convenient to change.

Claims

A kind ofly form by parts such as valve body, flashboard and handwheels, be used for the conveyance conduit of liquid, solid mixing two phase flow or the one-board wear-resistant sluice valve of other device, it is characterized in that flashboard (2) serves as a contrast with high-abrasive materials such as resilient abrasive rubber or engineering plastics with the surface of the relative side of the flow direction of liquid, solid mixing two phase flow, and use screw bolt reinforcing, there are two skewbacks (3) on the surface of flashboard opposite side, skewback (3) cooperates with two inclined-plane gussets on the valve body (5), flashboard (2) connects with wearing pin (4) with screw rod (1), and there is handwheel (6) on the top of screw rod (1).
