Abstract
The utility model discloses a big diameter balanced three-way governing valve which comprises a valve body, an upper valve cover, a valve plug and a valve rod, wherein the valve body is hollow, and is provided with three accesses which are respectively arranged on the bottom and two sides of the side wall of the valve body, the upper valve cover is connected on the upper end of the valve body through a bolt, the valve plug is arranged on the valve body capable of moving up and down, and is sealedly contacted with the inner wall of a sleeve barrel, the valve plug is straight tubular, the upper end of the valve plug is opened with balance holes which are symmetrically distributed, the lower end of the valve rod and the valve plug are fixedly connected, the upper end of the valve rod extends out of the upper valve cover, and the side wall is sealedly contacted with the upper valve cover. The structure of the utility model is novel, and the valve plug adopts the balance type, namely the upright top side of the valve plug is opened with six triangular balance holes, thereby greatly reducing the unbalance force caused by big pressure difference between the front and the rear of the valve in the closed state of the valve plug, reducing configuration of an actuating mechanism, and improving reliability and service life of products.
Description
Technical field
The utility model relates to a kind of valve, particularly is applicable to a kind of heavy caliber balanced type three-way control valve of the temperature of heat exchanger adjusted fluid.
Background technique
The three-way control valve of temperature that is applicable at present heat exchanger adjusted fluid both at home and abroad is equal, and what adopt mostly is the uneven formula of single seat, and its pressure reduction that bears is less.When field working conditions pressure reduction is big, need select for use high thrust actuator just can drive, thereby cause actuator bigger than normal, top-heavy situation appears.Domestic fertile inside nominal diameter is less simultaneously, and maximum inside nominal diameter can only arrive DN350.Also there is not producer to produce for the triple valve more than the DN400 is domestic, the complete basically import of domestic device, the price of a deck valve is difficult to bear as general enterprise up to more than 300 ten thousand yuan really.
The model utility content
The purpose of this utility model provides a kind of heavy caliber balanced type three-way control valve, and this three-way valve is simple in structure, and balance is good, and the pressure reduction that bears is big.
For solving the problems of the technologies described above, technological scheme provided by the utility model is: a kind of heavy caliber balanced type three-way control valve, this three-way valve includes valve body, bonnet, valve plug and valve rod, described valve body is a hollow shape, be provided with three gateways, described three gateways are located at respectively on the both sides of the bottom of valve body and sidewall; Described bonnet is connected the valve body upper end by bolt; Described valve plug can be located in the valve body up or down, and contacts with the sleeve lining sealing; Described valve plug is made as straight-tube shape, and its upper end has the equalizing orifice of symmetrical distribution; Fixedly connected with valve plug in described valve rod lower end, bonnet is stretched out in its upper end, and sidewall contacts with the bonnet sealing.
This three-way valve also includes sleeve, and the sidewall of described sleeve has the through hole that is communicated with the body wall gateway; Described sleeve is installed in the valve body, and sealing contacts with valve plug with valve interior wall.
Described sleeve is made as upper bush and lower sleeve, and described upper bush is fixedlyed connected with lower sleeve; All have through hole on the sidewall of described upper bush and lower sleeve, be connected with the gateway, both sides of body wall respectively.
Be provided with packing ring and spring energy-storage seal ring between described upper bush and the lower sleeve, described spring energy-storage seal ring is provided with 2 at least, is located at the interior outside of packing ring respectively.
Be provided with automatic compensation filler device between described valve rod sidewall and the bonnet, described automatic compensation filler device comprises graphite layer and butterfly spring, and described graphite layer is located at the butterfly spring below.
The advantage that the utlity model has: this product structure novelty, valve plug adopts the balanced type setting, promptly directly over valve plug, have six leg-of-mutton equalizing orifices, thereby reduce under the valve plug closed condition unbalanced force that produces greatly because of pressure reduction after and before the valve greatly, reduce actuator's configuration, improve reliability of products and working life.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of valve plug;
Fig. 3 is the partial enlarged drawing among Fig. 1.
Embodiment:
A kind of heavy caliber balanced type three-way control valve shown in Fig. 1,2 and 3 mainly is made up of valve body 1, bonnet 2, valve plug 4, valve rod 3, upper bush 6, lower sleeve 7, cushion block 8, seal ring 9 and automatic compensation filler device 5.Valve body 1 is a hollow shape, is provided with three gateways, is respectively gateway, bottom 11, the gateway 12 on the sidewall and the gateway 13 of valve body 1; Bonnet 2 is connected valve body 1 upper end by bolt; Valve plug 4 can be located in the valve body 1 up or down, and contacts with upper bush 6, lower sleeve 7 inner wall sealings; Valve plug 4 is made as straight-tube shape, its upper end has the equalizing orifice 41 of symmetrical distribution, have six leg-of-mutton equalizing orifices 41 directly over the valve plug 4 shown in Figure 2, mainly be that the gateway on gateway, bottom 11 and the sidewall 12 is ganged up, thereby reduce under the valve plug closed condition unbalanced force that produces greatly because of pressure reduction after and before the valve greatly.Fixedly connected with valve plug 4 in valve rod 3 lower ends, bonnet 2 is stretched out in its upper end, and sidewall contacts with bonnet 2 sealings.
Automatically compensation filler device 5 comprises butterfly spring 51 and graphite layer 52, and graphite layer 52 is located at the below of butterfly spring 51.Graphite packing wearing and tearing, the giving load and can guarantee that situation about leaking outside does not appear in medium of belleville spring 51 automatically with filler extrusion-deformation sealed valve stem.
Balance cage three-way valve is divided into balanced type three-way converging valve and balanced type diverging three way valve according to on-the-spot technological requirement.Balanced type three-way converging valve is that the gateway 12 and 13 on the body wall is advanced, and gateway, bottom 11 goes out; The flow direction of balanced type diverging three way valve is then opposite, and for advancing gateway, bottom 11, the gateway 12 and 13 on the sidewall goes out, thereby realizes one tunnel inlet fluid is divided into the two-way outlet fluid, perhaps the two-way inlet fluid is synthesized a way outlet fluid.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, though the utility model discloses as above with preferred embodiment, yet be not in order to limit the utility model, any those skilled in the art, in not breaking away from the technical solutions of the utility model scope, when the technology contents that can utilize above-mentioned announcement is made a little change or is modified to the equivalent embodiment of equivalent variations, in every case be the content that does not break away from technical solutions of the utility model, according to technical spirit of the present utility model to any simple modification that above embodiment did, equivalent variations and modification all still belong in the scope of technical solutions of the utility model.
