The copper gate valve is provided with an upper valve body, a lower valve body, a valve rod, a hand wheel and a gate plate, wherein the upper valve body and the lower valve body are connected by a nut; the valve rod is arranged in the upper valve body and the lower valve body; the upper part of the valve rod is connected with a trapezoidal thread of the upper part of the upper valve body; the hand wheel is arranged at the top part of the valve rod; the hand wheel and the valve rod are connected in a conical square groove manner and are locked by a ball head nut; the hand wheel is rotated to drive the valve rod to rotate and lift so as to realize the opening and closing of the valve; the gate plate and the valve rod are movably connected in a T shape; and the valve rod and the gate plate are arranged at the lower part in the lower valve body.
Description
Technical field
The utility model relates to a kind of gate valve, especially relates to a kind of blass stop valve that adopts rising stem (RS.) lifting type valve rod.
Background technique
Gate valve be widely used in every profession and trade hot and cold water, oil product and all kinds of non-corrosiveness gas/liquid etc. as open, block or controlling plumbing fixtures in the visual plant of working medium, shortcoming such as existing gate valve ubiquity installation and maintenance dismounting is inconvenient, working efficiency is lower, sealing is relatively poor, working life is short.
Publication number provides a kind of visual dark rod flat plate gate valve for the application for a patent for invention of CN101408096, form by valve body, valve seat, flashboard, valve rod, valve gap, pressure cap, indication vernier, handwheel etc., be provided with two sections screw threads that rotation direction is identical, pitch is different at the two ends up and down of valve rod; The screw thread of lower end is a trapezoidal thread, is connected with hoisting nut on being installed in flashboard; The screw thread of upper end is a V thread screw, and the indication vernier is enclosed within on the valve rod by V thread screw; The indication sleeve is a metallic cylinder, has a vertical opening in the one side, indicates aperture tolerance scale in the both sides of opening; The indication jacket casing the indication vernier outside and be fixed on the pressure cap; Outside at the indication sleeve is separately installed with transparent cover and protective housing.This invention has that the valve body load performance is good, switching torque is little, accurately the indicator cock state, environmental suitability is strong and characteristics such as safe and reliable.
Publication number comprises valve body for the application for a patent for invention of CN101435511 provides a kind of blind rod type knife-shaped gate valve, and flashboard is installed in the valve body, and gland is installed above the valve body.The top in valve body front vertically is fixedly connected with connecting plate, the top of connecting plate is fixedly connected with the top board of level, between top board and the leading screw thrust-bearing is installed, the other end of top board vertically is fixedly connected with connecting rod downwards, fixedlys connected with the reverse side of valve body in the bottom of connecting rod; Leading screw vertically is installed on the top board, and the upper end of leading screw is equipped with handwheel, and the bottom of leading screw is connected with nut; Nut is fixedlyed connected with the flashboard top in the described valve body; Described flashboard is a knife-edge, and the bottom of flashboard has blade.This invention leading screw length is the leading screw length 1/2 of rising stem knife-shaped gate valve, conservation.This invention processing technology is simple, has strengthened the intensity of pipeline, enhances productivity.Install and use when opening with former valve length remain consistent, the saving space.
Summary of the invention
The purpose of this utility model is shortcomings such as the installation and maintenance dismounting that exists at existing gate valve is inconvenient, working efficiency is lower, sealing is relatively poor, working life is short, provide that a kind of installation and maintenance dismounting is more convenient, working efficiency is higher, sealing is better, working life is longer, the blass stop valve of employing rising stem (RS.) lifting type valve rod.
The utility model is provided with upper valve body, following valve body, valve rod, handwheel and flashboard, be connected by nut between upper valve body and the following valve body, valve rod is located in upper valve body and the following valve body, and valve rod top is connected with upper valve body top trapezoidal thread by stuffing nut, and handwheel is located at the valve rod top, handwheel is that taper four directions groove is connected with valve rod, and by bulb nut check, rotation hand wheel drives valve rod and rotates lifting, realizes the valve ON/OFF, flashboard and valve rod flexibly connect for T shape, and the valve rod flashboard is located at down bottom in the valve body.
Described valve rod is preferably rising stem (RS.) lifting type valve rod.
The filler of between valve rod top and upper valve body top, preferably packing into.
Because upper valve body adopts the conical surface to be tightly connected firmly with following valve body, realize no bedding and padding sealing, and by the attaching nut with upper valve body and the locking of following valve body, so upper valve body and following valve body be fast joint structure, upper valve body and following valve body joint do not have stuffing box packing, sealing is reliable, energy-conserving and environment-protective, and installation and maintenance convenient disassembly, working efficiency is higher, manufacture cost is lower, and working life is longer.Because valve rod and valve plate flexibly connect for T shape, so valve and valve plate automatic positioning seal.Because valve rod adopts rising stem (RS.) lifting type valve rod, valve rod is that trapezoidal thread is connected with upper valve body, handwheel is that taper four directions groove is connected with valve rod, and by bulb nut check, so rotation hand wheel drives valve rod rotation lifting, switch is steady flexibly, feel is easily comfortable, realizes the valve ON/OFF, in the ON/OFF process, the valve rod automatic lifting can be observed the switching position state of valve well.Because main copper product, the especially materials such as brass/bronze and stainless steel of adopting, as through suitable treatment process, can obviously improve its resist collide, performance such as corrosion-resistant, antiscour, and the switch self lubricity is good, switch is smooth and easy flexibly,
Working medium of the present utility model can be water, non-corrosive liquid/gas, saturated vapour etc., and nominal pressure can reach 2.0MPa, and operating temperature t can reach-20 ℃≤t≤200 ℃.
