Embodiment Construction

[0008] The specific content of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0009] like figure 1 As shown, the check valve includes: a valve body 1, a valve cover 2 is arranged on the valve body 1, and a mutually perpendicular channel 3 and a valve disc 4 cooperating with the channel 3 are arranged in the valve body 1, and the valve disc 4 Set in the cylinder body 5, an inspection port 6 is provided on the outside of the cylinder body 5, and a bolt 7 is arranged on the inspection port 6. The valve disc 4 is offset against one end of the valve stem 8, and the other end of the valve stem 8 extends out of the valve cover 2 The upper valve mother 9 is connected with the handle 10.

[0010] The above-mentioned check valve is installed on the pipeline, and has two functions of a stop valve and a check valve at the same time, with small friction force and convenient cleaning and maintenance.

Abstract

The invention discloses a check valve which is convenient to clean. The check valve comprises a valve body, a valve cover is arranged on the valve body, vertical channels and valve clacks matching with the channels are arranged in the valve body, the valve clacks are arranged in a cylinder body, a slag removing hole is arranged at the outer side of the cylinder body, a bolt is arranged on the slag removing hole, the valve clacks butt against one end of a valve rod, and the other end of the valve rod extends out of a valve nut on the valve cover and is connected with a handle. The check valve is arranged on a pipeline and has the double functions of the stop valve and the check valve, the frictional force is small, and the maintenance and cleaning are convenient.

Description

technical field [0001] The invention relates to a valve, in particular to a check valve. Background technique [0002] In order to effectively cut off the fluid in the pipeline, valves will be arranged on the pipeline. Existing valves generally have only one function of cut-off or check, the function is relatively single, the friction is relatively large, and cleaning and maintenance are inconvenient. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a check valve which is easy to clean. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a check valve, comprising: a valve body, a valve cover is arranged on the valve body, channels perpendicular to each other and valve flaps cooperating with the channels are arranged in the valve body, The valve disc is set in the cylinder body, and there is an inspection port on the outside of the cylinde...
