The utility model belongs to valve applications field, relates in particular to a kind of Novel control ball valve.
Background technique
It is the widely used class control valves of industry such as Coal Chemical Industry, refinery, papermaking that C type is controlled ball valve, and medium is mainly fibre-bearing, high viscosity, contains the fluid of solid particle.In control valve field, frictional force is to affect one of modal factor of control valve ride quality, the frictional force that C type is controlled ball valve is mainly that spool remains to contact with valve seat and brings, whole control procedure operational torque is all larger, control dumb, and the wear problem of valve seat and spool is more serious, affects working life.
Model utility content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides a kind of and can reduce frictional force and improve the Novel control ball valve in working life.
The technical solution of the utility model is achieved in that a kind of Novel control ball valve, it comprises valve body, be arranged on the spool of valve inner and be resisted against the valve seat on spool, described valve body is provided with the first passage for media flow, described Novel control ball valve also comprises the baffle plate of restriction valve seat motion and the valve seat gland coordinating with valve seat, described valve seat is provided with the protuberance raising up, between described protuberance and baffle plate, be provided with the first Sealing, between described protuberance and valve seat gland, be provided with the second Sealing, between described valve seat gland and valve seat, be provided with the gap being communicated with first passage.
Described Novel control ball valve also comprises the valve gap being arranged on valve body, and described valve gap is provided with the second channel being communicated with first passage, and gap is communicated with second channel; Described valve seat, valve seat gland and baffle plate are installed on valve gap.
Described Novel control ball valve also comprise connect spool and valve body below back shaft, is connected spool top valve rod, connect upper press cover above valve rod and valve body, be arranged on support on upper press cover and rack-mount driver part.
Described valve gap is arranged on valve body by bolt member; Described baffle plate is also arranged on valve gap by bolt member.
Described spool becomes C type, and valve body becomes eccentric structure with spool.
The utility model also comprises the baffle plate of restriction valve seat motion and the valve seat gland coordinating with valve seat by described Novel control ball valve, described valve seat is provided with the protuberance raising up, between described protuberance and baffle plate, be provided with the first Sealing, between described protuberance and valve seat gland, be provided with the second Sealing, between described valve seat gland and valve seat, be provided with the gap being communicated with first passage, valve seat gland and baffle plate are by the motion of the second Sealing and the first Sealing restriction protuberance, and then limited the motion of valve seat, the first passage that flows to valve body when medium is inner, and then be filled in gap, then medium can promote valve seat and make valve seat remain and contact with spool, with medium, promote to replace the elastic member of prior art to promote, can reduce friction, when Novel control ball valve is worked, medium just promotes valve seat and contacts with spool like this, when Novel control ball valve is not worked, valve seat does not just contact with spool, can improve working life like this.
Accompanying drawing explanation
Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.
Fig. 1 is the structural representation of Novel control ball valve of the present utility model.
Fig. 2 is the local structure for amplifying schematic diagram of A part in the Novel control ball valve shown in Fig. 1.
In figure: valve body 1, spool 2, valve seat 3, valve gap 4, back shaft 5, valve rod 6, upper press cover 7, support 8, driver part 9, baffle plate 10, valve seat gland 11, protuberance 12, the first Sealing 13, the second Sealing 14, first passage 15, gap 16, second channel 17.
Embodiment
Consult shown in Fig. 1 to Fig. 2, the utility model discloses a kind of Novel control ball valve, it comprises valve body 1, be arranged on the spool 2 of valve inner, be resisted against valve seat 3 on spool 2, be arranged on valve gap 4 on valve body 1, connect spool 2 and valve body 1 below back shaft 5, is connected spool 2 tops valve rod 6, connect valve rod 6 and valve body 1 top upper press cover 7, be arranged on support 8 on upper press cover 7, be arranged on the driver part 9 on support 8, the baffle plate 10 that restriction valve seat 3 moves and the valve seat gland 11 coordinating with valve seat 3.Described valve seat 3, valve seat gland 11 and baffle plate 10 are installed on valve gap 4.
2 one-tenth C types of described spool, and 2 one-tenth eccentric structures of valve body 1 and spool, can make 2 pairs of valve seats 1 of spool have cam wedging effect like this, and 2 pairs of valve seats of spool 1 keep certain sealing force.
Described valve seat 3 is provided with the protuberance 12 raising up.Between described protuberance 12 and baffle plate 10, be provided with the first Sealing 13.Between described protuberance 12 and valve seat gland 11, be provided with the second Sealing 14.Described baffle plate 10 is by being resisted against on the first Sealing 13, and then the first Sealing 13, against protuberance 12, can limit the motion of valve seat 3 like this, avoids spool 2 to cause excessive pressure.
Described valve body 1 is provided with the first passage 15 for media flow.Between described valve seat gland 11 and valve seat 3, be provided with the gap 16 being communicated with first passage 15.Described valve gap 4 is provided with the second channel 17 being communicated with first passage 15.Described gap 16 is communicated with second channel 17.
Described valve gap 4 is arranged on valve body 1 by bolt member.Described baffle plate 10 is also arranged on valve gap 4 by bolt member.Be convenient to like this maintenance and change, saving cost.
During control ball valve work of the present utility model, have first passage 15 inside that medium flows to valve body 1, and then be filled in the gap 16 of valve seat gland 11 and valve seat 3, then medium can promote valve seat 3 and make valve seat 3 remain and contact with spool 2, with medium, promote to replace the elastic member of prior art to promote, can reduce friction.When Novel control ball valve is worked, medium just promotes valve seat 3 and contacts with spool 2 like this; When Novel control ball valve is not worked, valve seat 3 does not just contact with spool 2, can improve working life like this.
