Description
Technical field
The utility model relates to ball valve field, relates in particular to a kind of high platform flange floating ball valve.
Background technique
Ball valve is that spheroid rotates to realize the valve of unlatching, closing motion around valve body center line, the advantages such as wear-resisting, switch is light, long service life, good seal performance that it has.Along with updating of scientific and technical develop rapidly, production technology and product structure, ball valve is widely used in industries such as petroleum refining, long-distance transport pipes, chemical industry, papermaking, pharmacy, water conservancy, electric power, municipal administration, iron and steel, occupies very important status in national economy.
Floating ball valve is a kind of of ball valve, and its spheroid floats, and under pressure medium effect, spheroid can produce certain displacement and be pressed on the sealing surface of outlet end, guarantees outlet end sealing.At present, on market, floating ball valve mainly contains two kinds of common high platform ball valve and gland ball valves.Wherein, common high platform ball valve mainly compresses filler with filler pressing sleeve, hexagon thin nut, butterfly spring, and this ball valve mainly contains following several problem: the precompressed degree of depth that 1. can not accurately control gland filler; 2. to compensate the effect of filler compression be not very desirable for butterfly spring and nut; If 3. valve driving mode is worm gear, electronic or pneumatic, the filler of this structure, in the situation that occurring to leak, need to be dismantled drive unit and could compress filler, and this has affected working efficiency to a great extent.Gland ball valve is mainly to compress filler with Gland and socket head screw, the main driving mode of this valve is manual, if client needs electronic or pneumatic driving mode, so just need support and Coupling Shaft to carry out connecting drive device, this can increase undoubtedly cost and reduce working efficiency.
Model utility content
The purpose of this utility model is to overcome the above-mentioned defect existing in prior art, and the high platform flange floating ball valve of a kind of simple in structure, easy to maintenance, long service life, good seal performance is provided.
For achieving the above object, the utility model provides following technological scheme:
A kind of high platform flange floating ball valve, comprise valve body, valve gap, valve rod, valve seat, spheroid, handle, described valve body is connected by flange with described valve gap, in the ball chamber that described spheroid forms between described valve body and described valve gap, described spheroid both sides are provided with described valve seat, described valve body is provided with the mounting hole plugging for described valve rod, described valve rod is through described mounting hole and the interlock of described spheroid, in the Seal cage of described valve rod and described valve body, be provided with filler and Gland, the outer end, top of described valve rod is connected with described handle, described valve seat is lip formula elastic seat, between described valve seat and described spheroid, form primary seal and secondary sealing, described Gland is provided with gland bolt.
Preferably, the material of described valve seat is teflon, contraposition polyphenyl, polyether-ether-ketone or tetrafluoroethylene.
Preferably, the primary sealing area of described valve seat is rounded shapes, and the secondary sealing area of described valve seat and the cylindrical of described spheroid form tangent draft angle.
Preferably, the gap between the arc round angle of the major and minor sealing of described spheroid and described valve seat is 0.3～0.8 millimeter.
Preferably, the back side draft angle of described valve seat is 15 °～20 °.
Preferably, in the lower end of described valve rod, be provided with groove, in described groove, lay static spring and steel ball.
Compared with prior art, the utlity model has following beneficial effect:
(1) simple and compact for structure, simple to operate, easy to maintenance, good seal performance, long service life;
(2) valve seat back side draft angle has elastic compensating function, has good compensation sealing function in the prooving of valve seat and low pressure situation;
(3) adopt the structure of Gland and gland bolt to compensate compressible filler compression, effective;
(4) client can select manual, electronic, pneumatic and other driving mode as required voluntarily, in the situation that there is leakage at filler place, can just can be by tighting a bolt to compress filler without removal handle and drive unit, guarantee that filler place do not leak.
(5) valve seat is lip formula elasticity teflon valve seat, at high pressure and low pressure, have good sealing effect, it is light that this valve seat has the moment of keying, thereby reduce the specification of drive unit, and then cost-saving, reduce client and because valve seat is frequent, change the loss bringing.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment technology, to the accompanying drawing of required use in embodiment's technical description be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the Local map of high platform flange floating ball valve of the present utility model.
Fig. 2 is the partial enlarged drawing of lip formula elastic seat.
Fig. 3 is the partial enlarged drawing of gland bolt.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, the utility model embodiment's technological scheme is carried out to clear, complete description.
