Abstract
An eccentric semi-spherical valve with a composite valve core body comprises a valve seat and an eccentric semi-spherical valve core, wherein the eccentric semi-spherical valve core comprises a valve core body and a rubber layer, and the rubber layer is integrally vulcanized on the hemisphere of the valve core body. The eccentric semi-spherical valve has the advantage of better sealing performance due to the rubber layer integrally vulcanized on the eccentric semi-spherical valve core.
Description
Technical field
The utility model relates to the Liquid valve field.Relate in particular to a kind of eccentric half-ball valve with the combination valve core body.
Background technique
Existing eccentric half-ball valve mainly is made of valve seat, eccentric semi-spherical spool, valve core rod and valve handle, and its deficiency is to fall short of working life, and sealability is good inadequately, and using effect is good inadequately.Valve handle directly links to each other with valve core rod, and valve handle is directly moved valve core rod and easily caused the valve core rod fracture.Its valve core rod and eccentric semi-spherical spool are not one simultaneously, installation method is side-mounted, promptly earlier spool is packed into from the valve seat liquid inlet and outlet, after again valve core rod being inserted in the valve core rod hole of valve seat, link to each other with spool, during the maintenance spool, valve need be unloaded from pipeline and could take out the spool maintenance, very inconvenient.
The model utility content
The purpose of this utility model is exactly at the above-mentioned deficiency of existing eccentric half-ball valve, and a kind of eccentric half-ball valve with the combination valve core body is provided.
The utility model comprises valve seat and eccentric semi-spherical spool, and the eccentric semi-spherical spool is made of valve core and rubber layer, and the whole sulfuration of rubber layer is on the hemisphere of valve core.
On the valve seat of the hemisphere touching position of valve seat and valve core, be welded with the alloy-layer of anticorrosion antiwear, and the alloy-layer of anticorrosion antiwear adopts the spheric structure design.
On the eccentric semi-spherical spool, be provided with valve core rod with its one.
Valve is provided with turns one's head, turn one's head by the folder spool body of rod, clamping bolt, curved scale chi, limiting stopper and valve handle, be fixed with scale at valve seat and indicate pin and limiting stopper, curved scale chi and limiting stopper are installed in respectively on the folder spool body of rod, or curved scale chi and limiting stopper and the folder spool body of rod are one; Be fixed with scale with the valve seat of curved scale chi corresponding section and indicate pin, be fixed with stop block with the valve seat of limiting stopper corresponding section, valve handle is installed on the folder spool body of rod.On valve core rod, clamping bolt is installed in the folder spool body of rod one end to the folder spool body of rod by the folder valve core rod borehole jack on it.
The utility model has the advantages that:
1, owing to whole sulfuration on the eccentric semi-spherical spool has rubber layer, thereby sealability is better.
2,, and adopt spheric structure design owing on the valve seat of the hemisphere of valve core and valve seat contacting point, be welded with the alloy of anticorrosion antiwear, thereby longer service life.
3, owing on the eccentric semi-spherical spool, be provided with valve core rod with its one, valve seat adopts goes up the design of dress formula, the eccentric semi-spherical spool directly can be packed into from the valve core rod hole of valve seat during installation, during the maintenance spool, do not need valve is unloaded from pipeline, only need open valve core rod port lid cap and just can take out the spool maintenance, very convenient.
4, because bore is the eccentric half-ball valve of 12.5mm-65mm is provided with and turns one's head, by the valve handle open and close valve on turning one's head, can prolong valve core rod working life effectively, avoid valve handle directly to move valve core rod and cause the valve core rod fracture.Simultaneously on turning one's head, be provided with calibrated scale, be convenient to observe the opening and closing amount of valve.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model structural representation of turning one's head.
Embodiment
As shown in Figure 1, the utility model comprises valve seat 1 and eccentric semi-spherical spool, the anticorrosion antiwear alloy-layer 1-1 that on the valve seat of valve seat 1 and the hemisphere touching position of valve core 2, is welded with sphere shape, and the alloy-layer 1-1 of anticorrosion antiwear adopts the spheric structure design.On the eccentric semi-spherical spool, be provided with valve core rod 2-2 with its one.The eccentric semi-spherical spool is made of valve core 2 and rubber layer 3, and rubber layer 3 whole sulfurations are on the hemisphere of valve core 2.
As shown in Figure 2, the utility model is turned one's head in addition, bore is that the eccentric half-ball valve of 12.5mm-65mm is turned one's head by the folder spool body of rod 4, clamping bolt 5, curved scale chi, limiting stopper (it is spacing to be used for valve core rotation) and valve handle 8, be fixed with scale at valve seat 1 and indicate pin and stop block, curved scale chi 6 and limiting stopper are installed in respectively on the folder spool body of rod 4, or curved scale chi 6 and limiting stopper 7 are one with the folder spool body of rod 4; Be fixed with scale with the valve seat 1 of curved scale chi 6 corresponding sections and indicate pin, be fixed with stop block with the valve seat 1 of limiting stopper 7 corresponding sections, valve handle 8 is installed on the folder spool body of rod 4.On valve core rod 2-2, clamping bolt 5 is installed in the folder spool body of rod 4 one ends, is used to make the folder spool body of rod that valve core rod is clamped by the folder valve core rod borehole jack on it for the folder spool body of rod 4.
Claims (1)
1. the eccentric half-ball valve with the combination valve core body comprises valve seat and eccentric semi-spherical spool, it is characterized in that the eccentric semi-spherical spool is made of valve core and rubber layer, and the whole sulfuration of rubber layer is on the hemisphere of valve core.
