Abstract
The utility model is a kind of novel parallel double-flashboard electric gate valve, belongs to the valve field such as thermoelectricity, nuclear power, chemical industry.The utility model double disc parallel seat electric gate valve is arranged on supercritical thermal power unit pipeline, is used for cutting off (connection) pipeline steam or water.The utility model is made up of parts such as valve body, valve seat, support, valve rod, filler chamber, closing mechanism device adopts flap, clamping ring, spring composition, and valve body lumen adopts pressure self-tightening sealing, and pressure more high sealing performance is better, between two flaps, spring is housed, by spring tension auxiliary seal.Flap is fixed in clamping ring by baffle plate, screw, nut, opening and closing of valve drives clamping ring, flap to do elevating movement by means of the guiding of valve seat by valve rod, valve rod top limiting board moves up and down at support fluting place and nonrotational, steering force minor valve opens and closes freely, and can accurate control valve stroke.
Description
Technical field
The utility model relates to a kind of novel parallel double-flashboard electric gate valve, belongs to the valve field such as thermoelectricity, nuclear power, chemical industry.
Background technique
The utility model double disc parallel seat electric gate valve is arranged on vapour, the waterpipes such as thermoelectricity, nuclear power generating sets and chemical industry, is the visual plant cutting off medium.
At present, the double disc parallel seat electric gate valve of prior art owing to being equipped with spring between two flaps, flap fluting place is only bolted in clamping ring by two little steel discs, during assembling valve under spring force, flap bottom is always opened, need flap just can be made to load in valve body by special tool, and then take out special tool, very inconvenient and efficiency of assembling is low.
Summary of the invention
The utility model double disc parallel seat electric gate valve problem to be solved is: replace original two little steel discs with baffle plate, be fixed by screws in flap fluting place, flap is made to become to be integrated with clamping ring, because the radius of baffle plate is identical with the radius at flap fluting place, after fluting place puts into baffle plate, flap has tightly been clamped again with bolt, during assembling valve, even if under spring force, flap bottom also can not be opened, and valve body can be loaded smoothly, substantially increase efficiency of assembling and eliminate special tool simultaneously.
The technology that the utility model adopts: comprise valve body (1), spring (2), valve seat (3), flap (4), baffle plate (5), screw (6), valve rod (7), limiting board (8), support (9) stud (10) filler chamber (11) clamping ring (12) etc.Valve seat and valve body are welded to connect, and flap is connected by clamping ring with valve rod, and valve rod drives flap to move up and down along valve seat, in the middle of two flaps, spring is housed, under spring force, flap and sealing surface of seat close contact is fitted like a glove and reaches sealing.
The utility model double disc parallel seat electric gate valve, has fluting at frame upper, and with unlatching, the closedown of valve, the limiting board on valve rod top moves up and down at fluting place, and during valve wide open, flap also can not be thrown off with valve seat, so valve seat also has leading role.
The beneficial effect of the utility model double disc parallel seat electric gate valve: baffle plate is valve parts and valve frock, substantially increases efficiency of assembling and has economized the expense making frock simultaneously.

Embodiment
In the embodiment shown in fig. 1, flap circumference is fluted, the radius of flap groove is identical with the radius of baffle plate, after baffle plate loads flap groove, flap, baffle plate screw, nut and clamping ring are fixed as one, load in valve body, and then the nut that relaxes, make the spring in two flap intermediate groove under its tension force effect, flap and sealing surface of seat be fitted like a glove, reach good sealing.The engagement height of flap and sealing surface of seat when limiting board control valve Lift and valve closing.
Claims (6)
1. novel parallel double-flashboard electric gate valve, is characterized in that: it comprises valve body (1), spring (2), valve seat (3), flap (4), baffle plate (5), screw (6), valve rod (7), limiting board (8), support (9), stud (10), filler chamber (11), clamping ring (12); Valve seat and valve body are welded to connect, and flap is connected by clamping ring with valve rod, and valve rod drives flap to move up and down along valve seat, in the middle of two flaps, spring is housed, under spring force, makes flap and sealing surface of seat close contact reach sealing.
2. novel parallel double-flashboard electric gate valve according to claim 1, is characterized in that: the parallel valve seat of flap and moving up and down along valve seat all the time, has that resistance is little, the little feature of steering force.
3. novel parallel double-flashboard electric gate valve according to claim 1, is characterized in that: the filler at valve rod place compresses Gland by the stud implanted on filler chamber's top clamping plate and seals, and structure is simply easy to operation.
4. novel parallel double-flashboard electric gate valve according to claim 1, is characterized in that: flap, sealing surface of seat surfacing cobalt base hard alloy, wear-resisting scrape resistence between sealing surface during valve opening and closing.
5. novel parallel double-flashboard electric gate valve according to claim 1, it is characterized in that: with screw, baffle plate, flap and spring are fixed in clamping ring during assembling, make it into and be integrated, after loading valve body, loose nut is free state, and initial tension of spring keeps flap and valve base sealing.
6. novel parallel double-flashboard electric gate valve according to claim 1, is characterized in that: the limiting board on valve rod top moves up and down with flap at support fluting place, and keeps not throwing off with valve seat all the time, thus makes valve seat have guide function.
