Abstract

The utility model discloses a double-ball sealing ball valve, comprising a valve body, two ball valves and a by-pass valve, wherein the valve body is provided with the two ball valves parallelly, the by-pass valve is arranged on the side face of the valve body between the two ball valves. With one ball valve closed and the by-pass valve opened, the fluid in a pipeline can be discharged out completely in order to examine and repair the pipeline, which is simple and convenient to operate. In addition, the utility model has a simple and compact structure and long service life.

Description

Two ball seal ball-valves
Technical field
The utility model relates to a kind of pipeline valve, the pipeline valve that relates in particular to a kind of convenient maintenance and use.
Background technique
Valve be widely used in producing and life in, valve service time of a specified duration usually to produce dirt or breakage, therefore, use a period of time to need valve is overhauled or cleans later; On the other hand, the pipeline that is connected with valve uses day also to be damaged unavoidably long afterwards, therefore needs sometimes pipeline is overhauled.
Before maintenance, fluid in the pipeline need be drained, traditional valve is normally closed the two ends of pipeline, remaining fluid in the pipeline is drained, this method has two drawbacks: one, needed to drain a large amount of fluids before maintenance, the fluid of discharge needs a bigger parking space, sometimes, it is difficult seeking so big stock space, especially all the more so when fluid is some special liquids; Two, fluid a large amount of in the pipeline is discharged the loss that also can cause fluid, the energy day by day deficient also be a kind of waste now.
In order to overcome the deficiency of above-mentioned valve, be necessary to develop a kind of valve of convenient maintenance.
Simultaneously, the temperature of the fluid of carrying in pipeline usually will change, and sometimes, the convection cell temperature has special requirement, therefore need keep certain fluid temperature (F.T.) in pipeline, so that detect.
Summary of the invention
The valve that the technical problems to be solved in the utility model provides a kind of convenient maintenance and uses.
The utility model adopts following technical proposals to be achieved: a kind of pair of ball seal ball-valve, comprise a valve body, two ball valves and a bypass valve, and on valve body, be set up in parallel two ball valves, a bypass valve is set on the valve body side between two ball valves.
When needs overhaul, can close one of them ball valve, open another ball valve and bypass valve, the fluid in the pipeline is discharged from bypass valve, treat promptly to overhaul after fluid drains.When in use,, can open bypass valve, fluid is discharged from bypass valve, treat that fluid in the pipeline reaches after the suitable temperature, close bypass valve again, transport fluid into next flow process if the fluid in the pipeline does not reach suitable temperature.
One of them ball valve comprises sealed spheroid, upper valve rod, lower valve rod, seal ring, the O RunddichtringO, spring, gland and pressing plate, be provided with the sealed spheroid that is complementary with valve body inner bore in the valve body, on the sealed spheroid, the lower end is connected with lower valve rod with upper valve rod respectively, upper valve rod stretches out outside the valve body, upper valve rod overcoat one gland, insert filler between gland and the upper valve rod, be provided with a pressing plate between gland top and the handle, with screw pressing plate is fixed on the valve body, the sealed spheroid both sides are respectively equipped with seal ring, go up cover one O RunddichtringO seal ring with outer week, spring is equipped with in the seal ring outside, the spring the other end is connected with gland, and the effect of spring is to regulate the tightness degree that seal ring contacts with sealed spheroid, and the gland the other end is connected with flange.
Described bypass valve comprises by-pass valve body, flap, pad, valve rod, the sealing lock sleeve, locking nut, valve pocket and handwheel, the valve rod front end connects flap, the rear end connects handwheel, cover one valve pocket and a sealing lock sleeve on the valve rod between flap and the handwheel, the valve pocket inner chamber is connected with the valve rod outside thread, the valve pocket outside thread is connected with sealing lock sleeve rear threads, and lock with locking nut, the through hole of a stepped shape is established in by-pass valve body inside, by-pass valve body one side is provided with a by-pass hole, the sealing lock sleeve is threaded with through-hole wall, a pad is housed, the valve pocket front end between sealing lock sleeve front end and the through hole, filler is equipped with in gap between sealing lock sleeve and the valve rod.During use, rotate handwheel, drive valve rod and outwards move, reserve the space between flap and the through hole, fluid flows through through hole, flows out from by-pass hole; The backward rotation handwheel drives valve rod and moves inwards, and through hole is closed.
In order to realize being connected with pipeline, described valve body two ends are provided with flange, are fixed with nut, and the flange by two ends is with the valve connecting tube.
The utlity model has following advantage: 1. two ball valves are set, and a bypass valve is set betwixt, can reach the purpose that drains fluid by controlling two ball valves and bypass valve, simple, convenient 2. is simple in structure, compact, long service life.
