Abstract
A wedge nonmetal seal gate valve is provided, wherein, two opposite ends of a valve body are provided with openings; an opening at the upper end of the valve body is provided with a valve cap; a pressing cap is arranged on the valve cap; the outside of a valve stem which is clamped on the valve cap is convexly provided with a shaft shoulder; and the upper part of the shaft shoulder passes through a seal component and a pressing cap in the valve cap, a handwheel is positioned on the top end outside the valve body, a screw on the lower part of the valve stem is provided with gate which has inner thread meshing with the screw; two sides of the gate are respectively corresponding to two valve seats in the valve body; the gate is a nonmetal gate; a metal bush is best to be arranged on a meshing part of the nonmetal gate and the screw. The gate is a nylon gate. The utility model not only has no noise while opening or closing, but also has the advantages of good seal performance, no leakage and long service life; the gate can not be rusted, and the gate is of very flexible switching and small torsion force even long-time used; massive precious nonferrous metals is saved, and the cost of the valve is reduced; the gate in the gate valve can be exchanged, so that the gate can be easily manufactured; meanwhile, the service life of the whole valve can be prolonged as the gate can be changed.
Description
Technical field
The utility model relates to a kind of gate valve.
Background technique
The kind of gate valve has much at present, wherein with the gate valve of the utility model structural similarity be on October 27th, 1999 utility model patent communique disclosed a kind of＜gate valve (patent No. 98237899.8) its main structure is: the relative two ends of hollow valve body are opening, the opening of valve body upper end is provided with valve gap, which is provided with pressure cap.Be stuck in the valve rod evagination shaft shoulder on the valve gap, black box and the pressure cap in the valve gap passed on its top, and it is positioned at the outer top of valve body and is provided with handwheel.The screw rod of stem lower portion is provided with the flashboard of internal thread and its engagement, and these flashboard both sides are corresponding with two valve seats in the valve body respectively.Its deficiency is: 1) flashboard be copper material its with the steel valve seat between be that rigidity contacts, though be that valve seat at each flashboard correspondence carries out abrasive machining again when the manufacturing of gate valve, its sealing is existing problems still, use just not begin seepage for a long time, and leakage rate are than higher.2) in order to solve sealing, people have to strengthen cooperating between flashboard and the valve seat, make the manufacturing difficulty of gate valve big.3) because flashboard and valve seat process one to one, therefore can not exchange and change, in case flashboard or valve seat go wrong, whole valve just can not use, and has shortened the working life of valve.4) valve seat is a ferrous metal, and corrosion takes place under the effect of valve inner fluid easily, makes switch dumb, and torsional moment is big, can make valve ineffective when serious.5) flashboard will cause the cost of valve too high, uneconomical with valuable non-ferrous metal.
Summary of the invention
The purpose of this utility model is to provide that a kind of good seal performance, cost are low, long service life, the easy nonmetal sealing damper valve of wedge-type of manufacturing.The utility model mainly is the copper flashboard that replaces existing gate valve with nonmetal flashboard.The utility model is based on prior art, be that the relative two ends of hollow valve body are opening, the opening of valve body upper end is provided with valve gap, which is provided with pressure cap, be stuck in the valve rod evagination shaft shoulder on the valve gap, black box and the pressure cap in the valve gap passed on its top, and it is positioned at the outer top of valve body and is provided with handwheel, the screw rod of stem lower portion is provided with the flashboard of internal thread and its engagement, and these flashboard both sides are corresponding with two valve seats in the valve body respectively.Above-mentioned flashboard is nonmetal flashboard, and the structure of this nonmetal flashboard, shape are all identical with copper flashboard structure, the shape of existing gate valve.These nonmetallic material can be nylon, teflon, engineering plastics etc.According to user's requirement, this metal flashboard can have the polytype of different conditions such as being suitable for high temperature, middle temperature, low temperature.For increasing the intensity of nonmetal flashboard, be preferably in the part that nonmetal flashboard is meshed with screw rod and establish metal lining, as copper bush, stainless steel lining, carbon steel lining etc.When processing is about to metal lining during flashboard and nonmetal flashboard connects together.
The utility model has following advantage compared to existing technology: 1) the non-rigid contact between flashboard and the valve seat, not only switch noise free, and good seal performance, non-leakage, long service life.2) corrosion can not take place in flashboard, even long-time the use, its switch is also very flexible, torque force is little.3) save a large amount of valuable non-ferrous metals, reduced the cost of valve.4) flashboard in the gate valve can exchange, and makes the easy manufacturing of flashboard; Flashboard also can be changed simultaneously, has prolonged the working life of whole valve.
Description of drawings
Fig. 1 is that the utility model example 1 main looking partly cutd open schematic representation.
Fig. 2 is that the utility model example 2 main looking are partly cutd open schematic representation.
Fig. 3 is that the master of Fig. 2 flashboard looks and partly cuts open schematic representation.
Embodiment
Look the master of the nonmetal sealing damper valve of wedge-type shown in Figure 1 and partly to cut open in the schematic representation, hollow valve body 1, its relative two ends are opening, the opening of valve body upper end is provided with valve gap 2, is provided with pressure cap 3 again in the upper end of valve gap.Be stuck in the valve rod evagination shaft shoulder on the valve gap, its top is passed successively and is located at black box 6 and the pressure cap that is made of metal washer 4, retaining ring 5, metal washer and sealing material in the valve gap, and it is positioned at the outer top of valve body and is provided with handwheel 7.The screw rod of valve rod 8 bottoms is provided with the nylon flashboard 9 that internal thread is meshed with it, and these nylon flashboard both sides are corresponding with two valve seats 10 in the valve body respectively.Look the master of Fig. 2 and the nonmetal sealing damper valve of wedge-type shown in Figure 3 and partly to cut open in the schematic representation, other structure is all identical with example 1, and just the part that is meshed with screw rod at the nylon flashboard is established copper bush 11.
