Abstract
The utility model belongs to valve, and in particular to a kind of balance valve core structure and its balanced valve of the sleeve-type regulating valve with water conservancy diversion.A kind of balance valve core structure of the sleeve-type regulating valve with water conservancy diversion, sleeve including valve inner is arranged in, the spool of tubbiness is equipped in sleeve inner, setting section is the pod of taper in cavity below spool, the circulating window flowed for liquid is set on the side wall of pod, valve rod is set in the upper end of spool.The effect of the utility model is: the balance valve core structure described in this patent with water conservancy diversion, it is by the way that spool and pod to be installed together, relatively reasonable runner form is formed in valve opening, to realize the enhancing of valve negotiability, and the motion profile of working media is more in line with fluid motion rule, effectively reduces vortex.Its advantage is that it is simple and reliable for structure, retain the design of conventional sleeve formula regulating valve major part structure, only partial structurtes is needed to optimize.
Description
Technical field
The utility model belongs to valve, and in particular to a kind of balance valve core structure and its balance of the sleeve-type regulating valve with water conservancy diversion
Valve.
Background technique
Sleeve-type regulating valve, it is one of regulating valve product of mainstream the most currently on the market that technology is quite mature.
Sleeve-type regulating valve trim generally includes: sleeve, spool, valve rod, valve seat and other installation securing parts etc. pass through valve
Bar control valve core makees bidirectional-movement along center axis thereof in sleeve, reaches the function of realizing control flow.
Due to the unique design structure of sleeve-type regulating valve spool, when valve is in the open state, working media is easy
It is formed in the channel space that spool and sleeve are constituted compared with large eddy, reduces the negotiability of valve and cause a degree of attached
Plus-pressure loss, under the conditions of specific operation, vortex develops phenomena such as easily causing vibration, the noise of valve, influences valve
Service life and it is unfavorable for staff and carries out related operation in the environment of valve operation.
Utility model content
The utility model is designed to provide a kind of balance valve core structure of the sleeve-type regulating valve with water conservancy diversion, is that one kind is used for
Improve sleeve-type regulating valve negotiability, reduce the new structure being vortexed.
The technical solution of the utility model is: a kind of balance valve core structure of the sleeve-type regulating valve with water conservancy diversion, including setting exists
The sleeve of valve inner is equipped with the spool of tubbiness in sleeve inner, and setting section is the water conservancy diversion of taper in the cavity below spool
It covers, the circulating window flowed for liquid is set on the side wall of pod, valve rod is set in the upper end of spool.
Foregoing a kind of balance valve core structure of the sleeve-type regulating valve with water conservancy diversion, wherein sleeve is arranged in valve body
Valve seat on.
A kind of foregoing balance valve core structure of the sleeve-type regulating valve with water conservancy diversion, wherein baffle is set on valve seat,
Hole is opened on baffle, the size of through-hole is matched with the cross section size of pod top taper.
The valve core structure of a kind of balanced valve of the sleeve-type regulating valve with water conservancy diversion, the valve uses foregoing spool knot
Structure.
The effect of the utility model is: the balance valve core structure described in this patent with water conservancy diversion, is by by spool and pod
It is installed together, forms relatively reasonable runner form in valve opening, to realize the enhancing of valve negotiability, and work
The motion profile for making medium is more in line with fluid motion rule, effectively reduces vortex.Its advantage is that it is simple and reliable for structure, retain normal
The design of sleeve-type regulating valve major part structure is advised, only partial structurtes is needed to optimize.
When spool and valve seat contact, valve is in close state.Start when spool is detached from valve seat until spool unlatching is arrived
Until when maximum travel position, this stroke section is the working range of sleeve-type regulating valve.
Pod is installed in spool lower part, working media can be made by the integrated mode that pod and spool are installed together
Motion profile is more in line with fluid motion rule.It is compared with conventional sleeve formula regulating valve, original valve circulation energy can be effectively improved
Power reduces the purpose of vortex.
Detailed description of the invention
A kind of balance valve core structure closed position schematic diagram of the sleeve-type regulating valve of Fig. 1 with water conservancy diversion；
A kind of balance valve core structure open position schematic diagram of the sleeve-type regulating valve of Fig. 2 with water conservancy diversion；
Balanced valve fluid motion track schematic diagram of Fig. 3 the application sleeve-type regulating valve with water conservancy diversion；
Fig. 4 conventional sleeve formula regulating valve fluid motion track schematic diagram.
In figure: 1 valve body；2 valve seats；3 sleeves；4 pods；5 spools；6 valve rods；7 circulating windows.
Specific embodiment
A kind of balance valve core structure of the sleeve-type regulating valve with water conservancy diversion, including the sleeve 3, In inside valve body 1 is arranged in
The spool 5 of tubbiness is equipped with inside sleeve 3, setting section is the pod 4 of taper, the side of pod 4 in the cavity below spool 5
The circulating window 7 flowed for liquid is set on wall, valve rod 6 is set in the upper end of spool 5.
Sleeve 3 is arranged on the valve seat 2 of valve body 1.
Baffle is set on valve seat 2, hole, the size of through-hole and the cross section size of 4 top taper of pod are opened on baffle
Matching.
The effect of the application valve core structure is concentrated mainly on: when valve in the open state, liquid is by valve seat 2
Through-hole enters.When the liquid of flowing encounters the pod 4 of taper, liquid is pushed to circulating window 7, therefore liquid being capable of fast direct
What is connect passes through valve.If opposite without this conical flow guiding cover 4, in addition to partially liq can be by circulating window 7, there are also portions
Liquid separation, which knows from experience to be formed in the cavity of spool 5, to be vortexed, and hinders other liquid by valve, reduces the circulation of valve.
