Abstract
The utility model discloses a kind of emptying shut-off valves, it mainly include valve body, flap, valve rod, valve deck, Packing seat, filler, gland, bracket, electric device, guiding diameter, body base channel is provided with the flap with valve body cooperation, guiding diameter is installed on flap outer diameter, flap upper end connects valve rod, valve rod passes through the central axis of valve deck, Packing seat is glued on the upside of valve deck outer edge, filler is glued on the upside of Packing seat, top end of the valve body connecting bracket, cantilever tip installs electric device, and electric device bottom centre connect with valve stem top.The utility model design distinguished is in common shut-off valve, it can be installed on vertical pipe without leaking vapour, self sealing structure can when pressure is higher the anti-leak-stopping vapour of back seal self-tightening, with back seal (also known as upper sealing) structure, energy replacement filler with pressure, can reduce flow resistance coefficient while increasing valve chamber.
Description
Technical field
The utility model relates to shut-off valve fields, and in particular to a kind of emptying shut-off valve.
Background technique
Shut-off valve is to give sealing surface one downward pressure using valve rod torsion, by valve rod pressure, make valve clack sealing surface and
Sealing surface of seat fits closely, and prevents the inflow of medium.Flap is for linear motion along the center line of fluid.Shut-off valve only allows to be situated between
, there are direction requirement in matter one-way flow, when installation.In general shut-off valve is only applicable to standard-sized sheet or full pass.The control mode of shut-off valve
Generally have it is manual, electric, pneumatic, surge and it is electro-hydraulic linkage etc. various ways, structural union have internal screw thread, external screw thread,
Flange and welded connecting etc..Traditional shut-off valve is only applicable to be mounted on horizontal pipe substantially, but the emptying on boiler is cut
Only valve is because the requirement of operating condition need to install on vertical pipe.Traditional shut-off valve is on vertical pipe because of the original hung under flap
Because of the phenomenon that will appear leakage vapour certainly, and it is also easy leakage when pressure is higher, filler cannot be replaced when with pressure.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art, and provide a kind of emptying shut-off valve.
The purpose of this utility model is completed by following technical solution: this emptying shut-off valve, mainly includes valve
Body, flap, valve rod, valve deck, Packing seat, filler, gland, bracket, electric device, guiding diameter, body base channel are built-in
There is the flap with valve body cooperation, design on flap fluted, guiding diameter is installed on flap outer diameter, flap upper end connects valve rod,
Valve rod passes through the central axis of valve deck, and Packing seat is glued on the upside of valve deck outer edge, is glued with filler, valve body top on the upside of Packing seat
Connecting bracket is held, cantilever tip installs electric device, and electric device bottom centre connect with valve stem top.
The valve body has big lumen diameter, and valve body upper-end inner diameter is close to valve deck outer diameter, Packing seat and filler.
Gland is passed through in the middle part of the valve rod, gland is embedded between valve rod and valve deck, constitutes self sealing structure, again
It, can replacement filler with pressure with back seal (also known as upper sealing) structure.
The utility model has the following beneficial effects:
1, it is different from common shut-off valve, can be installed on vertical pipe without leaking vapour.
2, self sealing structure can when pressure is higher the anti-leak-stopping vapour of back seal self-tightening.
3, there is back seal (also known as upper sealing) structure, it can replacement filler with pressure.
4, it can reduce flow resistance coefficient while increasing valve chamber.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of common shut-off valve.
Fig. 2 is the structural schematic diagram figure of the utility model.
Fig. 3 is the lumen cross-sectional view of the utility model.
Description of symbols: valve body 1, flap 2, valve rod 3, valve deck 4, Packing seat 5, filler 6, gland 7, bracket 8, electricity
Dynamic device 9, guiding diameter 10.
Specific embodiment
Detailed introduction is done to the utility model below in conjunction with attached drawing:
As shown in Fig. 2, this emptying shut-off valve includes mainly valve body 1, flap 2, valve rod 3, valve deck 4, Packing seat 5, fills out
Material 6, gland 7, bracket 8, electric device 9, guiding diameter 10,1 foot passage of valve body are provided with the flap 2 cooperated with valve body 1,
Guiding diameter 10 is installed, 2 upper end of flap connects valve rod 3, and valve rod 3 passes through the central axis of valve deck 4, outside valve deck 4 on 2 outer diameter of flap
It is glued with Packing seat 5 on the upside of edge, filler 6,1 top connecting bracket 8 of valve body, the installation of 8 top of bracket are glued on the upside of Packing seat 5
It is connected at the top of electric device 9,9 bottom centre of electric device and valve rod 3.
The valve body 1 has big lumen diameter, and 1 upper-end inner diameter of valve body and 4 outer diameter of valve deck, Packing seat 5 and filler 6 are tight
Patch.
Gland 7 is passed through in the middle part of the valve rod 3, gland 7 is embedded between valve rod 3 and valve deck 4, constitutes self-sealing knot
Structure.
Shut-off valve gives sealing surface one downward pressure using 3 torsion of valve rod, by 3 pressure of valve rod, make 2 sealing surface of flap and
1 sealing surface of valve body fits closely, and prevents the inflow of medium.Flap 2 is for linear motion along the center line of fluid.Shut-off valve only allows
, there are direction requirement in medium one-way flow, when installation.
The utility model increases common 1 inner cavity of stop valve body, U-shaped guiding diameter 10 is added intracavitary, in stop valve clack 2
Upper processing groove, when shut-off valve is perpendicular to Pipe installing flap 2 can by guiding diameter 10 support not under the effect of gravity
It is lower extension and cause leak vapour.Since the pressure and temperature on boiler is comparatively higher, the connecting portion of valve body 1 and valve deck 4 is used
Back seal structure, the self-tightening in high pressure.
In general shut-off valve is only applicable to standard-sized sheet or full pass.The control mode of shut-off valve generally has manual, electric, gas
Move, surge and it is electro-hydraulic linkage etc. various ways, structural union have internal screw thread, external screw thread, flange and welded connecting etc..
It is understood that it will be understood by those skilled in the art that the technical solution of the utility model and utility model structure
Think of is subject to equivalent substitution or change all and should belong to the protection scope of the utility model the attached claims.
