Problems solved by technology

[0002] As we all know, the valve is a common part of the pipeline. The valve is used to control the opening, closing and flow adjustment of the pipeline. At present, the valves of the raw material pipeline adopt a tight sealing method, which is composed of a valve body, a valve stem and a valve core. The valve body There is a material inlet and a material outlet on the top, the valve core is matched with the material inlet, and the valve stem is connected with the valve core to control the working state of the valve core. The cooperation between the valve core and the material inlet or material outlet is The inlet or outlet is provided with a sealing boss, and the valve core is provided with a sealing ring surf

Example Embodiment

[0011] The present invention will be further described below in conjunction with the drawings.

[0012] As shown in the figure, a proportional valve with no tight seal is provided with a valve body 1, a valve stem 2 and a valve core 3. The valve body 1 is provided with a feed port 4 and a discharge port 5, and the valve body 1 can It is provided with one inlet and two outlets. The outlet is matched with the valve core. The valve body 1 can also be provided with two inlets and one outlet. The inlet is matched with the valve core. Suitable for different workplaces, the valve core 3 is matched with the inlet 4 and the outlet 5 with a conical surface. The inlet 4 or the outlet 5 is provided with a sealing boss 6, and the boss 6 has an inner hole. There is a tapered sealing ring surface, and the tapered sealing ring surface of the valve core is matched with the tapered sealing ring surface of the inner hole of the boss through the valve stem to realize the opening and closing of the v...

Abstract

The invention relates to a valve for a pipeline, and in particular to a packless sealing proportional valve. The packless sealing proportional valve is composed of a valve body, a valve rod and a valve core, wherein a charge port and a discharge port are formed in the valve body. The packless sealing proportional valve is characterized in that the valve core is matched with the charge port and the discharge port by conical surfaces, the charge port and the discharge port are provided with sealing bosses, and conical sealing annular surfaces are arranged in the inner holes of the bosses. During the use of the packless sealing proportional valve disclosed by the invention, the charge port and the discharge port are connected with a charge tube and a discharge tube by pipeline joint parts respectively, the flow, opening and closing of the charge port and the discharge port are controlled by a valve rod regulator flow valve core and the valve core, the valve core is matched with the charge port and the discharge port by means of conical surfaces, and the application of a pressure is not required during closing. The packless sealing proportional valve has the advantages of being convenient to regulate flow, tight in closing, long in service life, and the like.

Description

technical field [0001] The invention relates to a valve for pipelines, in particular to a non-tight sealing proportional valve with good sealing effect and long service life. Background technique [0002] As we all know, the valve is a common part of the pipeline. The valve is used to control the opening, closing and flow adjustment of the pipeline. At present, the valves of the raw material pipeline adopt a tight sealing method, which is composed of a valve body, a valve stem and a valve core. The valve body There is a material inlet and a material outlet on the top, the valve core is matched with the material inlet, and the valve stem is connected with the valve core to control the working state of the valve core. The cooperation between the valve core and the material inlet or material outlet is The inlet or outlet is provided with a sealing boss, and the valve core is provided with a sealing ring surface corresponding to the boss, and the sealing ring surface of the valv...
