The balance ball valve resolves the problems that due to the fact that a valve element of an existing ball valve is used for both closing the valve and adjusting flow, the service life of the valve element is short. The balance ball valve comprises a valve body, a valve rod and a shutoff valve element with a through hole, wherein the shutoff valve element is located in the valve body, the valve rod penetrates through the valve body, the inner end of the valve rod is connected with the shutoff valve element, the outer end of the valve rod is fixedly connected with a handle, the valve rod is in threaded connection of a balance valve element in the axial direction, two ends of the balance valve element extend out of the valve rod, the inner end of the balance valve element penetrates through the shutoff valve element and is communicated with the through hole of the shutoff valve element, and the outer end of the balance valve element is connected with a hand wheel capable of driving the balance valve element to rotate. The service lives of the valve elements are along, and the shutoff valve element is not used for balance adjustment, so that the shutoff valve element is not washed by fluid.
Description
Technical field
The utility model belongs to valve technology field, relates to a kind of equilibrium ball valve.
Background technique
Ball valve refers to that spool is driven by valve rod, and around the valve that the axis of valve rod rotates, and is mainly used in blocking or connect the medium in the pipeline.It has ball valve and revolves the action that turn 90 degrees, and spool is spheroid, manhole or passage is arranged by its axis.Ball valve is mainly used to make cut-out, distributes and change the flow direction of medium in pipeline, it only need just can be closed tightly with revolving the operation that turn 90 degrees and very little moment of rotation.Ball valve in the market all has only single closing function and does not possess regulatory function.And each space-heating system must carry out the heat supply network adjusting and hydraulic equilibrium is regulated, and for efficiently realizing this goal, people have designed a kind of V-type ball valve that can regulate flow.
A kind of V-type ball valve [patent No.: 201120058884.8] as the Chinese patent announcement, this V-type ball valve comprises valve body, valve seat, spheroid, valve rod, driving mechanism, Sealing and assembling set are formed, spheroid is semiglobe, be shaped on semi-circular channel on the hemisphere spheroid, valve rod is made up of upper valve rod and lower valve rod, spheroid and valve seat have the sealing surface that cooperatively interacts, mainly be that entrance end in the spheroid semi-circular channel is shaped on semicircle cutter type inclined-plane respectively, close in the closed procedure at spheroid, this cutter type inclined-plane scrapes off the particle of valve base surface, reduce particle to spheroid and valve base sealing surface wear, have characteristics such as good seal performance.But the spool of V-type ball valve namely is used for Shuttoff Valve, is used for again regulating flow, and it is more serious to be subjected to fluid erosion, causes shorten the working life of spool.
Summary of the invention
The purpose of this utility model is to have the problems referred to above at existing technology, has proposed a kind of equilibrium ball valve with shutoff and hydraulic equilibrium regulatory function.
The purpose of this utility model can realize by following technical proposal: a kind of equilibrium ball valve, comprise valve body, valve rod, the shutoff spool of band through hole, turn-off spool and be positioned at valve body, the inner that valve rod passes valve body and valve rod links with the shutoff spool, described valve rod outer end is fixed with handle, it is characterized in that, described stem shaft is to the balance valve core that has been threaded, valve rod is stretched out at described balance valve core two ends, described balance valve core the inner penetrates the shutoff spool and is connected with the through hole that turn-offs spool, and described balance valve core outer end is connected with and can drives the handwheel that balance valve core rotates.
In valve body, be provided with two spools, one is turn-offed spool and a balance valve core, handle with sleeve can drive and turn-off spool realization full closing state, and rotation moves up and down the relative valve rod of balance valve core thereby handwheel can drive balance valve core, realizes regulating traffic engineering capability.This equilibrium ball valve is a kind of comprehensive valve of uniqueness, integrates two kinds of specific functions.Turn-off function and hydraulic equilibrium regulatory function are integrated on the same valve body, when valve turn-offs, can influenced the position of the balance valve core of regulating action, guaranteed equilibrium ball valve perfectly control and adjusting function.
In above-mentioned equilibrium ball valve, described balance valve core the inner has the shoulder block of protrusion, and described valve rod the inner has the retaining edge corresponding with shoulder block.When moving on to certain position on the balance valve core, the retaining of shoulder block and valve rod is along leaning, and prevents that balance valve core from deviating from valve rod.
In above-mentioned equilibrium ball valve, described handwheel is threaded with the outer end of balance valve core.Itself has outside thread balance valve core, so handwheel is threaded with the outer end of balance valve core, manufacturing is installed all more convenient.
In above-mentioned equilibrium ball valve, be arranged with seal ring on the described balance valve core.Increase the sealing effect between valve rod and the balance valve core.
In above-mentioned equilibrium ball valve, described shutoff spool and the valve body place of leaning are provided with seal washer, also are provided with between described seal washer and the valve body to make seal washer be resisted against the spring that turn-offs on the spool all the time.Spring makes seal washer be pressed on the spherome surface that turn-offs spool all the time when turn-offing valve core rotation, guarantees to turn-off tight.
In above-mentioned equilibrium ball valve, described seal washer adopts the PTFE material to make.The seal washer good sealing effect of PTFE materials for support, anti-aging, durable in use.
Compared with prior art, this equilibrium ball valve has the following advantages:
1. have and turn-off and the hydraulic equilibrium regulatory function.
2. turn-off function and equilibrium function can both be worked under any pipe network operating mode without interfering with each other.
3. valve rod and balance valve core screw-thread fit, it is more accurate to regulate flow.
4. the spool long service life is used for the spool that turn-offs and is not used in balance adjustment, so can not be subjected to the erosion of fluid.
