Problems solved by technology

[0003] There are several types of connection between pipes and valves, such as flanges, threads, ferrules, and welding. To install valves and cut them off, the pipes must be processed or welded with flanges. However, some valves have complicated processes and in some environments, in In the absence of equipment, the installation of the valve cannot be completed

Embodiment 1

[0021] see Figure 1-5 , a quick-install shut-off valve, including a valve seat 6, a valve body 7, and an actuator 12; Simple, easy to operate and install. The upper side of the middle part of the valve body 7 is provided with an actuator structure 12 through the connecting flange, the middle part of the valve body 7 is provided with a valve seat 6, and the middle part of the valve seat 6 is provided with a ball 8, and the left and right sides of the ball 8 are provided with valves outward. 17. The top middle of the sphere 8 is provided with a valve stem 10 upward, and the interior of the valve body 7 on the left and right sides of the valve stem 10 is provided with a push rod 5 for controlling the opening and closing of the valve. The valve stem 10 is connected and installed with the actuator 12, The rear side of the actuator 12 is provided with a set of handles, and the actuator 12 is controlled by the handles to drive the valve rod 10 to be placed inside the sphere to move...

Embodiment 2

[0024] refer to Figure 1-3 , when the pipe body connected to the valve is a hose, a layer of auxiliary pre-tightening short joint 15 is provided on the inner curved surface of the connection between the valve 17 and the top plate 1, and the auxiliary pre-tightening short joint 15 is connected with the forming sealing ring 2, The pre-tightening sleeve 3 and the valve seat sealing ring 4 further improve the sealing performance and connection stability when the hose is connected.

[0025] In order to further improve the functionality of the shut-off valve, a jet assembly 16 with a conical structure is communicated with the outside of the valve 17 on the right side, through which the jet assembly 16 is convenient for irrigation or other purposes, and suitable accessories are selected to allow the fluid to flow in a certain way. Perform a pressure relief.

[0026] The working principle of the present invention is: place the left and right top plates 1, forming sealing ring 2, pre...

Abstract

The invention relates to the technical field of valves, and discloses a quick-assembly stop valve. The valve comprises a valve seat, a valve body and an executing mechanism. The left side and the right side of the valve body is of a symmetrical structure, the executing mechanism is arranged on the upper side of the middle of the valve body through a connecting flange, the valve seat is arranged in the middle of the valve body, a ball is arranged in the middle of the valve seat in a matched mode, valves are arranged on the left side and the right side of the ball outwards, a locking nut used for controlling the executing mechanism to move up and down is arranged on the upper side of the executing mechanism, an O-shaped sealing ring is arranged on the outer side of the middle of a valve rod, the outer sides of the valves on the left side and the right side of the valve body are provided with top plates in an outward extending mode, the outer portions of the sides, away from the ball, of the top plates are fixedly mounted on the valve body through bolts, formed sealing rings are arranged on the left portions and the right portions of the inner side curved surfaces of communicating positions of the valves and the top plates, the formed sealing rings has a size matching that of a selected pipe, pre-tightening sleeves are arranged in the middles of the forming sealing rings on the left side and the right side, and a circle of fast-assembling pre-tightening bolts are arranged on the outer portion of the valve body on the side, close to the ball, of the top plate.

Description

technical field [0001] The invention relates to the technical field of valves, in particular to a quick-install shut-off valve. Background technique [0002] Valves are pipeline accessories used to open and close pipelines, control flow direction, adjust and control the parameters (temperature, pressure and flow) of the conveying medium. The shut-off valve is a kind of actuator in the automation system, which is composed of a multi-spring pneumatic film actuator or a floating piston actuator and a regulating valve. The shut-off valve has a wide range of uses and can be used to cut off gas, combustion air, cold air and flue gas. [0003] There are several types of connection between pipes and valves, such as flanges, threads, ferrules, and welding. To install valves and cut them off, the pipes must be processed or welded with flanges. However, some valves have complicated processes and in some environments, in In the absence of equipment, the installation of the valve canno...
