Description
Technical field:
The utility model relates to a kind of ball valve, particularly relates to a kind of duplex pass ball valve.
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 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 levels of precision is low, namely the keying degree of two ball valves is difficult to reach consistent, brings 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, comprises two ball valves and a final controlling element, and two described ball valves are in the distribution that opposes up and down, 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; 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 to have returned the car 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; O-ring seal 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 a final controlling element 6, and two described ball valves are in the distribution that opposes up and down, 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, be provided with spheroid 4 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; 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 to have returned the car 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 O-ring seal between main flange plate and secondary flange plate, reach sealing.
The utility model is arranged by the ball valve of two parallel-connection structures, the valve rod 5 of two ball valves is directly connected by final controlling element 6, reach accurate, synchronous manipulation two spheroids, guarantee that validity is high, the keying degree of two spheroids consistent, bring great convenience to user.
