Abstract
The utility model provides a high temperature anti wearing gate valve applied in oil and chemical industry field, characterized in that a layer of bone net is fixed on position of the inner wall of a valve body and two sides which are easy to be washed and abraded, then a alumina lining (A1<2>O<3>) is lined between, thereby increasing the valve's property of anti high temperature and anti abrasion and prolonging the using life of the valve. In order to solve the problem that solid articles is stacked on the upper portion of the inner chamber of the valve body, a blowing valve which can communicate the steamer is equipped on the upper portion of the valve cover, and an exhaustion valve is equipped on the lower portion of the valve body. The valve is widely used in equipments of pipe valve catalytic cracking high temperature smoking and gas in an oil refinery and melamine, with a reliable usage of about three years using time.
Description
Technical field
The utility model relates to a kind of gate valve that is applied to oil, chemical field, specifically a kind of high temperature resistant, anti abrasive gate valve.
Background technique
Be applied to the oil refinery catalytic cracking and contain the high-temperature flue gas pipeline of catalyzer and the wear-resistant sluice valve on the melamine device, in the course of conveying of medium, because of the state of medium is a solid particle, very fast to the erosive wear of valve body, flashboard, and solid particle is easy to be deposited in valve cavity top.Existing wear-resistant sluice valve adopts the corundum (Al that applies one deck 0.2～0.5mm at the outer surface of valve body internal channel and flashboard respectively
2O
3), the defective that adopts coating is that coating is thin, and working life is short, and service time is only about half a year.
Summary of the invention
The purpose of this utility model is to provide a kind of gate valve of high temperature resistant, wear-resistant, long service life, existing gate valve wear resistant coating is thin to solve, working life short this defective.
For achieving the above object, the technological scheme taked of the utility model is:
A kind of high-temperature wearable gate valve, comprise valve body, flashboard, valve rod, valve gap, filler, support and Electric actuator, it is characterized in that easily washing away fixedly one deck skeleton of place, be lined with corundum lining (Al between skeleton and valve channel inwall, the flashboard in described valve channel inwall, flashboard both sides
2O
3).
The above-mentioned corundum lining (Al that is arranged between skeleton and valve channel inwall, the flashboard
2O
3) thickness is 15～30mm.
In order to solve the problem that solid particle is piled up on body cavity top, the blow down valve that can lead to steam also has been installed on valve gap top, and blowdown valve has been installed in valve body lower portion.
The above-mentioned high-temperature wearable gate valve that the utility model provides, at local first fixedly one deck skeleton of the easy erosive wear of valve channel inwall and flashboard both sides, lining is gone up corundum lining (Al betwixt then
2O
3), thereby improve high temperature resistant, the abrasion resistance properties of valve, prolonged the working life of valve, this valve is widely used on the device of the line valve of oil refinery catalytic cracking high-temperature flue gas and melamine, and practical reliable, service time is about 3 years.
Description of drawings
Accompanying drawing is high-temperature wearable gate valve embodiment's a structural representation
Among the figure: the 1-blowdown valve; The 2-skeleton; 3-corundum lining (Al

Embodiment
As shown in the figure, among the high-temperature wearable gate valve embodiment that the utility model provides, flashboard 5 in the valve body 4 links to each other with the bottom of valve rod 6, valve gap 7 is fixed together with valve body, the middle mouth of valve gap 7 is provided with stuffing box packing 8, the top of support 10 is provided with and drives the Electric actuator 11 that valve rod 6 moves up and down, this needle is to easily erosive wear position wear resistant coating is thin in the prior art, what working life, short this defective was done is improved to: in the vias inner walls of valve body 4, fixedly one deck skeleton 2 of place elder generation is easily washed away in flashboard 5 both sides, and then in skeleton 2 and valve body 4 vias inner walls, lining corundum lining (Al between the flashboard 5
2O
3) 3, corundum lining (Al
2O
3) 3 thickness is 15～30mm, what skeleton 2 adopted is the thick hexsteel of 20mm.
In addition, in order to solve the problem that solid particle is piled up on the inner chamber top of valve body 4, also installed on the top of valve gap 7 and can lead to the blow down valve 9 that solid particle that steam makes accumulation purges out, and blowdown valve 1 has been installed in the bottom of valve body 4.
Claims (4)
1, a kind of high-temperature wearable gate valve, comprise valve body (4), flashboard (5), valve rod (6), valve gap (7), filler (8), support (10) and Electric actuator (11), it is characterized in that easily washing away fixedly one deck skeleton (2) of place, be lined with corundum lining (3) between skeleton (2) and valve body (4) vias inner walls and the flashboard (5) in the vias inner walls and flashboard (5) both sides of described valve body (4).
2, high-temperature wearable gate valve according to claim 1 is characterized in that the above-mentioned thickness that is arranged on the corundum lining (3) between skeleton (2) and valve body (4) vias inner walls and the flashboard (5) is 15～30mm.
3, high-temperature wearable gate valve according to claim 1 and 2, what it is characterized in that above-mentioned skeleton (2) employing is hexsteel.
