Problems solved by technology

Among them, the conventional check valve is to install a valve clack with a spring in the valve body, and the valve clack is mostly made of metal. When the system is running, the valve clack and the valve body collide with each other during the operation process, causing a lot of noise.
Butterfly valves mostly use wafer butterfly valves. The connection between the two is through flanges, short pipes and fasteners. The installation is cumbersome, takes up a lot of space, maintenance is troublesome, and the investment is large.

Embodiment Construction

[0007] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0008] As shown in the figure, the valve is integrated, the upper and lower valve bodies (1), (2) are connected by connecting bolts (4), the upper and lower flanges (3), (13) are connected to the pipeline, and the lower flange (13) is threaded structure, the rotatable bonnet (11) is connected with it through threads, and the rotatable bonnet (11) can be opened to inspect and repair the check valve core (7). The check valve core (7) is built into the lower valve Inside the body (2), the contact part between the check valve spool (7) and the rotatable bonnet (11) is lined with a silicone gasket (8), between the check valve spool (7) and the positioning plate (5) Equipped with spring (6). Through the handle and connecting rod (16), the opening and closing of the valve disc (14) can be operated, and the connecting bolt (4) can be loosened to...

Abstract

The invention discloses a multifunctional integrated valve which is composed of an upper valve body (1), a lower valve body (2), an upper flange (3), a valve body connection bolt (4), a positioning plate (5), a spring (6), a check valve element (7), a sealing gasket (8), a sealing gasket pressing block (9), a set screw (10), a rotary valve deck (11), an O-shaped sealing ring (12), a lower flange (13), a valve clack (14), a sealing ring (15), a handle and a connecting rod (16). The multifunctional integrated valve is characterized in that an integrated structural design is adopted, a check valve is internally installed, the functions of original conventional butterfly valves and check valves are highly integrated, and therefore the multifunctional integrated valve is simpler and more convenient to install. Compared with the prior art, the multifunctional integrated valve solves the problem of complicated installation of a conventional water outlet check valve, a short pipe and a butterfly valve behind a pump, is easy and convenient to install, higher in leakproofness and novel and attractive in appearance, saves installation space and materials, integrates functions, lowers noise, and reduces the possibility of leakage.

Description

1. Technical field [0001] The invention relates to a multifunctional integrated valve, in particular to an integrated valve used for opening and closing pipelines of a water supply and drainage system and preventing backflow of water. It is especially suitable for the water outlet pipeline after the water pump, replacing the original short pipe, butterfly valve, check valve and other components. 2. Background technology [0002] At present, the existing technology for connecting the water outlet pipeline after the pump is to connect the water outlet main pipe behind the pump through a short pipe flange, a stop valve, a short pipe flange, a butterfly valve and other components through a lot of fastening bolts, so as to achieve the The function of opening and closing and preventing the backflow of water. Among them, the conventional check valve is provided with a valve clack with a spring in the valve body, and the valve clack is mostly made of metal material. When the system...
