Description
Technical field
The utility model belongs to valve technology field, specifically relates to a kind of stop valve.
Background technique
At present, need to assemble stop valve in the pipe-line system of many fluids, traditional stop valve adopts hard sealed type mostly, relies on the laminating between water intake and the water outlet of flap and valve body to complete sealing.This sealing surface is having relatively high expectations to machining accuracy aborning, and sealing effect is in use not good enough, in long-term use after the water intake or water outlet erosion corrosion of flap and valve body, the water intake of flap and valve body and water outlet laminating are not tight, the sealing effect variation of valve body, be easy to cause fluid leakage, have influence on normal production work, and the dwang of this stop valve coordinates tighter with positioning plate, in the time regulating fluid flow, flexibility ratio is bad, need be by instrument ability rotary valve rod, complex operation.
Model utility content
In order to address the above problem, the utility model provides a kind of stop valve, has reached good simplified structure and effect easy to adjust.
The utility model is achieved by following technical solution.
A kind of stop valve, comprise valve body, valve rod, flap, intake pipe, water outlet, positioning plate, dwang, seal ring and tightening nut, described intake pipe and valve body interconnection, described valve body one end is fixedly connected with the water outlet of ring-type, the other end is installed positioning plate, on described valve rod, be processed with screw thread, coordinate with positioning plate screwed hole of centre, valve rod front end is connected with flap simultaneously, and lock by locking nut, described flap outer rim coordinates with water outlet inner edge, and the surface of contact place of flap and water outlet is provided with seal ring, and valve stem end is provided with dwang.
The faying surface of described flap and described water outlet is funnel-like.
Described seal ring is made up of high temperature resistant silicon glue material.
The Placement of described intake pipe and valve body is argon arc protection weldering welding.
The Placement of described water outlet and valve body is argon arc protection weldering welding.
Between described positioning plate and valve body, be bolted.
The beneficial effects of the utility model are:
A kind of stop valve described in the utility model, by the faying surface of flap and water outlet is designed to funnel-like, the faying surface that makes flap and water outlet is larger, laminating is tightr, and significant sealing affection strengthens; By positioning plate is set on valve body, valve rod lower end is run through positioning plate and is connected with flap, has realized the control that flap is opened and closed; Upper end at valve rod is also hinged with a dwang, makes to be more convenient in the time of rotation valve rod firmly, no longer carrys out control valve by means of other instruments and opens and closes, and uses more convenient.
Brief description of the drawings
Fig. 1 is effect structure figure of the present utility model;
Fig. 2 is structure sectional view of the present utility model.
In figure: 1-valve body, 2-valve rod, 3-flap, 4-intake pipe, 5-water outlet, 6-positioning plate, 7-dwang, 8-seal ring, 9-tightening nut.
Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1 and Figure 2, a kind of stop valve described in the utility model, can be applicable in fluid line equipment, comprise valve body 1, valve rod 2, flap 3, intake pipe 4, water outlet 5, positioning plate 6, dwang 7, seal ring 8 and tightening nut 9, valve body 1, valve rod 2, flap 3 are metal material and make; Described valve body 1 is cylindrical shape, the mode that described intake pipe 4 protects weldering to weld with valve body 1 by argon arc is intersected and is communicated with, the water outlet 5 that is welded with ring-type is protected in valve body 1 one end by argon arc, the other end is installed positioning plate 6, and the axial angle between intake pipe 4 and water outlet 5 is 90 °; On described valve rod 2, be processed with screw thread, coordinate with positioning plate 6 screwed hole of centre, valve rod 2 front ends are connected with flap 3 through the center hole of flap 3 simultaneously, and lock by locking nut 9; Described flap 3 outer rims coordinate with water outlet 5 inner edges, and flap 3 is funnel-like with the faying surface of water outlet 5, makes the faying surface of flap 3 and water outlet 5 larger, and is provided with seal ring 8 at faying surface place, makes its better tightness; Valve rod 2 ends are provided with dwang 7, between drive link 7 and valve rod 2, are hinged, make valve rod 7 to make circumferential movement around hinge, and drive link 7 is rotated to the position vertical with valve rod 2, can be used as handle and carry out rotation valve rod 2, control the lifting of valve rod 2.
Described seal ring 8 is made up of high temperature resistant silicon glue material, in the time that the fluid temperature (F.T.) of the inside of valve body 1 is higher, also can meet the requirement of valve body 1 sealing, in addition, positioning plate 6 is provided with the surface of contact of flap 3 seal ring that high temperature resistant silicon glue material is made with surface of contact and the valve rod 2 of valve rod 2 with surface of contact, the positioning plate 6 of valve body 1, to ensure sealing completely in the chamber of valve body 1.
Between described positioning plate 6 and valve body 1, be bolted, in the time that needs clean valve body 1 inside, can directly dismantle positioning plate 6 and can clean, maintenance more for convenience.
When work, fluid enters into valve body 1 inside from intake pipe 4, in the time of needs exhaust fluid, only dwang 7 need be adjusted to the position vertical with valve rod 2, pull valve rod 7 around the shaft axis of valve rod 2, rotate counterclockwise valve rod 2, valve rod 2 rises, and drives flap 3 to detach the mouth of a river 5, and fluid can flow out from water outlet 5, being rotated further valve rod 2 increases the spacing of flap 3 and water outlet 5, can increase fluid drainage flow; In the time not needing exhaust fluid, only need clockwise rotate valve rod 2 by dwang 7, the spacing of flap 3 and water outlet 5 is reduced gradually, and finally fit tightly, fluid no longer flows out from water outlet 5.
