Abstract
The utility model relates to a light gate valve used for industrial pulp production. The valve is cast integrally, the lower part of a flashboard is in circular arc shape, a one-way chamfer angle and a valve rod are arranged, and the sealing surfaces of an inlet valve seat and an outlet valve seat are both made of stainless steel. The utility model has the advantages of small size, light weight, large diameter, high pressure resistant performance, strong sealing performance, convenient opening and closing, flexible opening regulation and no leakage, and the light gate valve is particularly suitable for overhead pipelines. The gate valve provides ideal advanced equipment for industrial pulp production for paper making, chemical fibre, sugar making, chemical industry, pharmacy, etc.
Description
The utility model belongs to mechanical engineering technical field.
What at present produce use for papermaking, chemical fibre, sugar industry slurrying is slim Gate valve of pulp.This valve body is to combine with two ironcastings, and flashboard is square and easily blocks slurry and stuck flashboard.Valve rod carbon steel manufacturing, in use easy deformation and corrosion.Because switch is dumb or be not closed completely and cause operator often firmly excessive, the retaining screw of screw, valve rod and flashboard of connection and the base plate below the valve body are destroyed.Because it is to form with the involutory back adjustment of two-part that the flashboard of valve body is led poor, influences the flexibility of flashboard translation easily, thus will mobile displacement once use, need readjust again and make troubles to production.
The purpose of this utility model is with the valve body cast inblock, and the bottom of flashboard is made as the circular arc chamfering, and inlet/outlet sealing surface of seat and valve rod all adopt the stainless steel manufacturing, to replace the slim Gate valve of pulp that can not adapt to the pulp industry development need.
Structure of the present utility model is to adopt flange to connect, and handwheel drives, the design that asbestos packing sealing, cast iron bracket are connected with valve body.Valve body is cast inblock; Have flashboard in the middle of the integrated type valve body and lead poorly, the flashboard bottom is circular and do not have the dead angle, and there is unidirectional chamfering at the radiused edges place.Valve rod, flashboard and inlet/outlet sealing surface of seat all adopt the stainless steel manufacturing.
The characteristics of new-type light-duty gate valve are: volume is little, in light weight, latus rectum is big, withstand voltage height, sealing are strong, opens, closes conveniently, and aperture is regulated flexibly, and no seepage and no leakage especially is adapted to aerial pipeline.Because valve rod, flashboard inlet/outlet sealing surface of seat all adopt the stainless steel manufacturing, so contact non-corroding with medium.Particularly this valve has adopted circular port and flashboard radiused edges place that the design of unidirectional chamfering is arranged, and valve body lower portion and medium channel are that circular arc does not have the dead angle, help squeezing slurry, thereby can prevent that also stuck flashboard from having avoided slurry to immerse filter and having done the stuck flashboard in back.It is cast form that the middle flashboard of this valve body is led poor, and its thickness does not need to adjust.Flashboard closely contacted with the left and right sides valve seat when flashboard cut out sealing, and tightness once mixes up the back and just can directly install and use when the valve seat of the assembling left and right sides.Flashboard and valve base sealing place all adopt corrosion-resistant stainless steel to make material, especially use to keep long sealing effect in containing acid and alkaline medium, and higher anticorrosive property is arranged.Light-duty gate valve structure is reasonable, and good integrity has guaranteed enough intensity.Basically remedied the defective that slim Gate valve of pulp exists from design angle and technological angle, for industrial slurrying productions such as papermaking, chemical fibre, sugaring, chemical industry, pharmacy provide more advanced, a desirable equipment, can play good effect to the development of pulp industry.
Its specific embodiment is as shown in the figure:
Fig. 1 is new-type light-duty gate valve front view.
Fig. 2 is a side view.
Support (4) is connected movingly with nut (3) in the present embodiment, and nut (3) is respectively fixing with handwheel (2) and valve rod (1) and is threaded.Valve rod (1) is connected rotation hand wheel (2) with flashboard (5) with bolt can make flashboard (5) upper and lower mobile, and there is unidirectional chamfering (11) at the radiused edges place, bottom of flashboard (5).Valve body (7), left valve seat (8) and right valve seat (9) cooperate formation flashboard sealing surface, and gland (6) is used the swing bolt compression fit with valve body (7), plays the top seal effect.Support (4) is connected with bolt with valve body (7), makes the two large divisions connect the formation overall structure.
Claims (2)
1, one is used for the new-type light-duty gate valve that industrial slurrying is produced, it is made of valve body (7), flashboard (5), valve rod (1), left valve seat (8), right valve seat (9), it is characterized in that valve body (7) is cast inblock, the bottom of flashboard (5) is a circular arc, and the sealing surface of valve rod (1) and inlet/outlet valve seat (8) valve seat (9) is all made with stainless steel.
2, as new-type light-duty gate valve as described in the claim 1., it is characterized in that there is unidirectional chamfering (11) at radiused edges place, flashboard (5) bottom.
