Abstract
The utility model discloses a wear-resistant composite valve. The utility model mainly comprises a valve body, a valve clack, a valve rod, a valve cover, etc. The valve body is composed of an outer shell (1) and an inner lining (2). The outer shell (1) is made of common steel material. The inner lining (2) is poured by wear-resistant material. The utility model has the advantages that the metallurgical bonding rate of the inner layer and the outer layer of the valve body is high, the integral performance is better, the wear-resistant performance and the toughness are good, the use is safe, and the service life is long. The wear-resistant composite valve of the utility model has various specifications, such as composite stop valves, composite diaphragm valves, composite ball valves, composite check valves, composite butterfly valves, etc.
Description
The utility model relates to valving or laminar product, particularly wear-resisting composite valve.
In the mine; metallurgical; in the industries such as electric power; the conveying of material all is that pipeline pressure is carried; in whole transportation process; valve plays a part control and regulates, the erosion and the wearing and tearing of also bearing medium simultaneously, the cast iron of single material or cast steel valve; wear resistance is relatively poor; working life is shorter, can not satisfy the requirement of operating mode well, in order to improve the working life of valve; general now employing rubber and plastics are compound; also obtained favorable economic benefit in production practices, but also had many deficiencys simultaneously, the associativity of rubber and plastics and steel body is poor; very easily layering; cause the inefficacy of coming unstuck, valve is scrapped in early days, simultaneously in the occasion that larger particles or sharp-pointed material are arranged; rubber and plastics are also very easily scratched; cause to come off, in addition in dry state or the higher occasion of temperature, rubber and plastics are softening easily; the forfeiture wear resistance; more can not the roasting or welding of fire, so rubber and plastics composite valve in use be subjected to many restrictions, can not satisfy various working condition requirements fully.
The purpose of this utility model is to provide the wear-resisting composite valve of the multiple industrial use of difformity and specification.This composite valve wear-resisting property is good, long service life.
Technical solution of the present utility model is achieved in that
Wear-resisting composite valve mainly comprises parts such as valve body, flap, valve rod, valve gap, handwheel, flange.Valve body is made up of shell (1) and liner (2) two-part, and shell (1) adopts common iron to make, and liner (2) is poured into a mould with wear-resistant material; Make valve body liner mould with foamed plastics, adopt disappearance mould process for suction casting that liner and shell are cast for one.
Valve shell (1) can select for use general steel plate or common steel tube to make, and liner (2) high-abrasive material can be selected general white cast iron, rich chromium cast iron or ni-hard cast iron for use.
This model utility has different shapes and specification, and the diameter dimension scope of valve body is 100～1000mm, and shell (1) wall thickness dimension is generally 4～8mm, and the wall thickness dimension of liner (2) is generally 8～50mm.
The utlity model has following advantage:
1. because the valve body skin is a common iron, internal layer is an abrasion resistance alloy, both compound moldings under the hot-cast state, its metallurgy combination rate is higher, and combination property is better, and good wear resistance is not only arranged, and shock resistance, reach the combination of toughness and wear resistance, safe and reliable, improve working life greatly.
2. because the inside and outside two-layer metallic material that is of valve body, all has certain resistance to high temperature, its thermal expansion coefficient is also suitable, therefore Applicable scope is wider, not only can in dry state, warm attitude operating mode, use, to in temperature sharply or in the occasion that often changes, can or not shrink yet and inconsistently cause that internal layer is cracked to be peeled off because of the expansion of internal and external layer, take place to scrap in early days.
3. manufacturing process is simple relatively, and steady quality can adopt Placements such as welding, flange, cutting ferrule, can be widely used in the industrial valve of various different sizes.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the structural representation of compound stop valve.
Fig. 2 is the structural representation of compound gate valve.
Fig. 3 is the structural representation of composite diaphragm valve.
Fig. 4 is the structural representation of compound ball valve.
