Background technique:
Ball valve is a kind of open-shut device is spheroid, is driven and the valve rotated around ball valve axis by manipulation valve rod, mainly in order to the regulating and control of fluid, the various pipes in production and life all has a wide range of applications.In harsh production pipeline, when existence two groups of pipelines need to carry out to collaborate or triage operator time, need difference mounting ball valve on two groups of pipelines, interflow or shunting is reached by the final controlling element controlling two ball valves, not only very loaded down with trivial details in operation, and traditional ball valve cannot reach demand on ball seal, bring great inconvenience to user.
Model utility content:
For the deficiencies in the prior art, the utility model provides a kind of duplex pass ball valve, comprise two ball valves and two final controlling element, two described ball valves be arranged in parallel in the same horizontal line, described final controlling element connects the valve rod of two ball valves respectively, and ball valve is made up of valve body, valve gap, valve seat, spheroid, valve rod.
The utility model solves the technological scheme that its technical problem adopts: be provided with flow ipe and outflow conduit in valve body, spheroid is provided with between flow ipe and outflow conduit, the both sides of spheroid are respectively equipped with valve seat, valve seat with the surface of contact of spheroid on be provided with Sealing shield ring, Sealing shield ring is made up of metal steel ring and O-ring seal, metal steel ring is circular steel ring, internal surface and the outer surface of metal steel ring are provided with annular groove, the degree of depth of annular groove is 1/3 of the width of metal steel ring, is respectively equipped with O-ring seal in annular groove; Described O-ring seal is woven by a metal spring and is formed, and metal spring is double layer construction, and the double layer construction of metal spring is connected to form O-ring seal by mutually oppositely misplacing, and O-ring seal surface does not exist gap; Metal steel ring upper surface is evenly provided with four square breach, and the circular arc between adjacent two square breach is 90 degree, conveniently takes out O-ring seal from metal steel ring; Spheroid top is provided with tapped through hole, valve rod through the tapped through hole on spheroid and spheroid tightly fixing; Valve body is provided with valve gap, and valve rod and valve gap surface of contact are provided with Gland, are provided with filler in Gland; Valve gap with the surface of contact of valve rod on be also provided with circular groove, groove is embedded with seal ring, and described seal ring is 3 circles; The both sides of valve body are equipped with main flange plate and time flange plate, and main flange plate is provided with through hole in order to connecting tube, and main flange is also provided with attachment hole, and secondary flange plate is fixed on main flange plate by bolt through attachment hole is dismountable; Annular gasket is provided with between main flange plate and secondary flange plate.
The beneficial effects of the utility model: easy for installation, validity is high, the keying degree of two spheroids is consistent.
Accompanying drawing illustrates:
Fig. 1 is overall structure figure of the present utility model;
Wherein, 1-valve gap, 2-valve body, 3-valve seat, 4-spheroid, 5-valve rod, 6-final controlling element.
Embodiment:
A duplex pass ball valve as shown in drawings, comprises two ball valves and two final controlling element 6, and two described ball valves be arranged in parallel in the same horizontal line, and described final controlling element connects the valve rod 5 of two ball valves respectively, gets final product synchronization control two ball valves by final controlling element 6; Ball valve is made up of valve body 2, valve gap 1, valve seat 3, spheroid 4, valve rod 5, flow ipe and outflow conduit is provided with in valve body 2, spheroid 4 is provided with between flow ipe and outflow conduit, the both sides of spheroid 4 are respectively equipped with valve seat 3, valve seat 3 with the surface of contact of spheroid 4 on be provided with Sealing shield ring, Sealing shield ring is made up of metal steel ring and O-ring seal, metal steel ring is circular steel ring, internal surface and the outer surface of metal steel ring are provided with annular groove, the degree of depth of annular groove is 1/3 of the width of metal steel ring, is respectively equipped with O-ring seal in annular groove; Described O-ring seal is woven by a metal spring and is formed, and metal spring is double layer construction, and the double layer construction of metal spring is connected to form O-ring seal by mutually oppositely misplacing, and O-ring seal surface does not exist gap; Metal steel ring upper surface is evenly provided with four square breach, and the circular arc between adjacent two square breach is 90 degree, conveniently takes out O-ring seal from metal steel ring; Spheroid 4 top is provided with tapped through hole, valve rod 5 through the tapped through hole on spheroid 4 and spheroid tightly fixing; Valve body 2 is provided with valve gap 1, and valve rod 5 and valve gap 1 surface of contact are provided with Gland, are provided with filler, in order to sealed valve stem in Gland; Valve gap with the surface of contact of valve rod on be also provided with circular groove, groove is embedded with seal ring, and described seal ring is 3 circles, effectively prevents fixing granule from slipping into or being stuck on valve rod; The both sides of valve body are equipped with main flange plate and time flange plate, main flange plate is provided with through hole in order to connecting tube, main flange is also provided with attachment hole, secondary flange plate is fixed on main flange plate by screw through attachment hole is dismountable, when the connection mouth dislocation of two side-by-side tubes cannot synchronously be installed, namely the connection mouth of two pipelines not point-blank time, accurately install fast by piling up several times flange plate to reach on main flange plate; Be provided with annular gasket between main flange plate and secondary flange plate, reach sealing.
