Abstract

The invention belongs to an improvement on a check valve installation structure of a conveying pipeline for fluid with solid impurities, and particularly relates to a check valve device normally working on the conveying pipeline for the fluid with the solid impurities. The check valve device comprises disc-shaped valve clacks, wherein each disc-shaped valve clack is arranged in a valve chamber of the corresponding check valve in a hinged mode, and matched with the corresponding valve seat, each valve clack is upwards turnover through a hinged shaft, and two or three check valves are installed on the conveying pipeline for the fluid with the solid impurities in series. The check valve device is reasonable in structure and reliable in performance, and can ensure that the check valves installed on the conveying pipeline for the fluid with the solid impurities work normally, and ensure that production is conducted successfully.

Description

At the check vavle device containing work normal on the fluid delivery pipeline of solid impurity
Technical field
The invention belongs to the improvement at the fluid delivery pipeline safety check mounting structure containing solid impurity, particularly a kind of at the check vavle device containing work normal on the fluid delivery pipeline of solid impurity.
Background technique
Original safety check is without any problem to pure flowing product unidirectional blocking, but unidirectional blocking is carried out for the product containing solid impurity in product then cannot, reason is: when on solid pad to the valve seat of safety check and the fitting surface of flap, safety check and generating portion or all malfunctioning, simultaneously because of the effect of product reflux pressure cause the solid matter pressure of pad valve stiff to the valve face of safety check to such an extent as to the punching of the follow-up product stream through valve opening do not walk to pad the stiff solid matter of valve and cause thorough backflow malfunctioning.
Summary of the invention
The object of the present invention is to provide a kind of at the check vavle device containing work normal on the fluid delivery pipeline of solid impurity, it is rational in infrastructure, reliable performance, can guarantee that the safety check be arranged on containing solid impurity fluid delivery pipeline is installed normally works, and guarantees carrying out smoothly of production.
The object of the present invention is achieved like this: a kind of at the check vavle device containing work normal on the fluid delivery pipeline of solid impurity, be included in the articulated discoid flap matched with valve seat in safety check valve chamber, flap is upwards overturn by hinge, containing 2-3 safety check that the fluid feed line of solid impurity is installed in series.
The present invention will be connected into multistage safety check being transformed into three containing the former single-stage safety check installed on the fluid delivery pipeline of solid impurity, and this check vavle device can realize aborning without malfunctioning backflow production purposes.
Its working principle is:
When solid impurity certain safety check paved cause one-way valve at the corresponding levels malfunctioning time other two safety check still closing the non-return that dams reliably.Simultaneously be not subject to backflow defeat stiff on valve seat or flap because solid matter institute paves malfunctioning safety check, until flow through fluid on valve seat or flap just wash away the solid matter of not pressing deadlock next time, make check valve set enter again the functional status of normal non-return.
The present invention is rational in infrastructure, reliable performance, ensure that the safety check that the fluid delivery pipeline that is arranged on containing solid impurity is installed normally works, ensure that carrying out smoothly of production.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described, and Fig. 1 is sectional structure schematic diagram of the present invention.
Embodiment
A kind of at the check vavle device containing work normal on the fluid delivery pipeline of solid impurity, as shown in Figure 1, be included in the articulated discoid flap 3 matched with valve seat 2 in safety check 1 valve chamber, flap 3 is upwards overturn by hinge 4, containing 2-3 safety check 1 that the fluid feed line of solid impurity is installed in series.The quantity of series connection safety check 1 is 3.

Claims (2)

1. the check vavle device of a normal job on the fluid delivery pipeline containing solid impurity, be included in the articulated discoid flap (3) matched with valve seat (2) in safety check (1) valve chamber, flap (3) is upwards overturn by hinge (4), it is characterized in that: containing 2-3 safety check (1) that the fluid feed line of solid impurity is installed in series.
