Problems solved by technology

[0003] The existing stop valve lacks the screw disc and sealing ring under the valve disc, so that the space orientation of the valve body itself affects the sealing performance, which brings great inconvenience to the use. This is the general stop valve must be horizontal The reason for the tightness can only be achieved when it is vertical, so the tightness of the stop valve is poor, and it is easy to leak water when it is closed.

Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0034] Such as Figure 1-8 As shown, the present invention provides a shut-off valve and a connection assembly between the shut-off valve and the pipeline, including a main valve body 1, a bottom plate 7 is fixedly installed on the top of the main valve body 1, and left and right sides of the main valve body 1 are fixedly installed respectively. Valve pipe 3 and right valve pipe 20, the inner wall of main valve body 1 is...

Abstract

The invention belongs to the field of pipeline valves, and particularly relates to a stop valve and a connecting pipe assembly for connecting the stop valve with a pipeline. The stop valve comprises amain valve body; a bottom plate is fixedly mounted at the top of the main valve body; a left valve pipe and a right valve pipe are fixedly mounted on the two sides of the main valve body respectively; and a first section and a second section which are connected with each other are fixedly mounted on the inner wall of the main valve body. According to the stop valve and the connecting pipe assembly for connecting the stop valve with the pipeline provided by the invention, a screw valve clack can be driven to rotate and move up and down through a threaded rod by rotating a rotary handle, then the screw valve clack can be in threaded connection with the inner side of a sealing ring, and when a rubber sleeve stops moving under the resistance of a limiting convex ring, the screw valve clack still moves downwards continuously; therefore, the rubber sleeve can be pressed to deform with an elastic pressing piece on the inner side of the rubber sleeve, the sealing performance during threaded connection of the screw valve clack and the sealing ring can be improved conveniently, and the problem that water leaks when the stop valve is closed due to poor sealing performance during threaded connection of an existing device is solved.

Description

technical field [0001] The invention relates to the field of pipeline valves, in particular to a shut-off valve and a connecting pipe assembly for connecting the shut-off valve to a pipeline. Background technique [0002] Globe valve, also known as cut-off valve, is a forced sealing valve, so when the valve is closed, pressure must be applied to the disc to force the sealing surface not to leak. When the medium enters the valve from the bottom of the disc, the resistance that the operating force needs to overcome is the friction between the valve stem and packing and the thrust generated by the pressure of the medium. The force to close the valve is greater than the force to open the valve, so the valve stem The diameter of the valve must be large, otherwise the failure of the valve stem to bend will occur. [0003] The existing stop valve lacks the screw disc and sealing ring under the valve disc, so that the space orientation of the valve body itself affects the sealing p...
