Abstract
The utility model belongs to the class of valves, in particular to a steam stop valve used in a steam pipeline. The utility model is mainly composed of a valve body, a valve cover, a valve disc, and a valve rod, wherein, the valve cover is connected with the valve body, and the valve rod is connected with the valve disc. The utility model is characterized in that the upper part of a valve seat is matched with the center part of the bottom of the valve disc; the lower part of the valve seat is matched with the inner wall of the starting end of the steam outlet of the valve body; the bottom edge of the valve disc contacts the lug boss of the starting end of the steam outlet. The utility model has the advantages of small wear, good sealing performance, low cost, and long service life, and the service life of the utility model whose price is one fifth of the price of a gate plate type steam stop valve is increased more than three times.
Description
The utility model belongs to valve type, relates generally to stop valve, the steam stop of promptly using in gas pipeline.
The steam stop of prior art is a flashboard type, i.e. valve rod drive flashboard moves up and down along chute, to reach by purpose.Because flashboard moves up and down frequently, contact surface abrasion is very fast between flashboard and the chute, cause cut after, it is bad to end effect, causes leakage vapour, does not have the effect that ends, must regularly change, generally be about a week.Because consider flashboard intensity, performance, general flashboard adopts stainless steel material, so the steam stop of existing structure has not only increased maintenance frequency, has increased maintenance expenses, and has had influence on ordinary production.
The purpose of this utility model provides and a kind of flashboard in the former stop valve is designed to valve disc with valve seat, thereby realizes improving the working life of stop valve, reduces cost, and reduces maintenance frequency, increases the disc type steam stop of sealing.
The utility model is by valve body, and the valve gap that is connected with valve body, the valve disc of connection valve rod and the valve seat that matches with intermediate portion, valve disc bottom constitute.The boss at steam (vapor) outlet top contacts in the bottom margin of valve disc and the valve body, and the inwall at the steam (vapor) outlet top that the bottom of valve seat and valve body are interior matches.
Valve disc be shaped as disc type, material is a cast iron, valve seat is a ring, its material can be Cuprum alloy.
The utility model is described in further detail below in conjunction with accompanying drawing:
Among the figure: 1 valve rod, 2 valve gaps, 3 valve discs, 4 valve seats, 5 valve bodies, 6 steam inlets, 7 steam (vapor) outlets.
Valve gap 2 links together by bolt and valve body 5, and valve rod 1 is connected with valve disc 3 in the valve body 5 by valve gap 2, and valve seat 4 matches with the intermediate portion, bottom surface of valve disc 3, and the top inwall of the steam (vapor) outlet 7 that its outer surface and valve body 5 are interior matches.When the needs air inlet, valve rod drives valve disc and valve seat rises, and steam is passed through by steam inlet 6 and steam (vapor) outlet 7; When not needing steam, valve rod promotes valve disc and valve seat falls, and matches with steam (vapor) outlet top inwall in the valve body, and this moment, the pressure of steam affacted the valve disc surface again, play one oppositely by effect, so it was better by effect.
Steam stop wearing and tearing of the present utility model are little, good seal, and cost is low, and long service life improve the life-span more than 2 times than former flashboard type steam stop, and its price is about 1/5th of flashboard type steam stop. Use the utility model disk-like steam stop valve, improved steam utilization, reduced equipment investment and maintenance frequency, satisfy technological requirement, and can not affect normal steam supply quality and quantity.
Claims (2)
1, a kind of disc type steam stop, comprise valve body 5, the valve gap 2 that is connected with valve body 5, valve disc 3 and connected valve rod 1, match with the intermediate portion, bottom of valve disc 3 in the top that it is characterized in that valve seat 4, match with the inwall at the steam (vapor) outlet top of valve body 5 in its underpart, valve disc 3 bottom margins contact with the boss at steam (vapor) outlet top.
2, disc type steam stop according to claim 1 is characterized in that: valve disc 3 be shaped as disc type, material is a cast iron, valve seat is a ring, its material is a Cuprum alloy.
