Abstract
The utility model of sealing type stop valve with a corrugated pipe, which is composed of a beam, a valve rod, a corrugated pipe seat, a corrugated pipe, a half ball valve, a valve seat, a valve cover, and a valve body. The upper end of the corrugated pipe and the corrugated pipe seat are welded into one body in a fully sealing way, and the lower end of the corrugated pipe and the half ball valve are welded into one body in a fully sealing way; the total sealing of the valve rod can be formed thereby. The utility model mainly solves the problem the phenomenon of the leakage of the valve in the existing pipeline can occur and thoroughly solve the phenomenon of the gas leakage of the existing valve, the normal operation of the pipeline can be ensured, and the consumed steam energy caused by gas leakage can be saved; the service life of the sealing type stop valve with a corrugated pipe can be extended, the maintenance cost can be reduced, and the cost for replacing new valves can be reduced.
Description
Bellow sealed cut-off valve of the present invention is a kind of stop valve that is used for industrial vapor line and central heating pipeline, and it has fundamentally solved the gas leakage problem of stop valve in the existing vapor line.
At present the stop valve in the vapor line is made up of valve, valve seat, valve rod, hand beam and valve body, often use soon during work, or vapor tension is when excessive, gas just from valve rod to external leakage, the one, wasted the steam energy, the 2nd, produce dangerous.Use this valve often to cause very big waste to country because of leak gas maintenance or frequently more shining new valve.
Bellow sealed cut-off valve of the present invention is by after having installed bellows additional, has thoroughly solved the vapour leakage problem, after reequiping bellows, and forms a kind of new seal arrangement.
Now the invention will be further described in conjunction with example and symbol figure.
Fig. 1 is a sectional drawing of the present invention.
With reference to Fig. 1, bellow sealed cut-off valve mainly is made up of hand beam [1], valve rod [2], corrugated header [3], bellows [4], semispherical valve [6], valve seat [7], valve gap [8], valve body [9].The upper end of bellows [4] and corrugated header [3] weldering are one, the lower end of bellows [4] and semispherical valve [6] weldering are one, welding is hermetically sealed welding, it is whole so just to have constituted a sealing by corrugated header [3], bellows [4], semispherical valve [6], therefore thoroughly sealed valve rod [2], thereby do not cause valve box [10] to communicate with valve rod [2], the circumferential edges that the gas when therefore working in valve box [10] can not pass through valve rod [2] is to external leakage, thereby reached the purpose that seals.The ripple degree of depth h of bellows [4] is 5mm to 100mm, and the pitch of waves L of bellows [4] is 4mm to 120mm, and the material of bellows [4] is that stainless steel material is made.The radius size of semispherical valve [6] is 30mm to 300mm.Semispherical valve [6] plays a part to open and close valve.At first open hand beam [1] during work, hand beam [1] drives valve rod [2] rotation, and at this moment semispherical valve [6] is opened, and steam flows into the air outlet from suction port by valve face.At first rotate hand beam [1] when closing valve, hand beam [1] drives valve rod [2], makes semispherical valve [6] close valve, and at this moment steam stops to flow.
Characteristics of the present invention are the leakage problems that fundamentally solved existing steam valve, have increased the use of valve In the life-span, reduced because of valve leak and maintenance or more renewed the economic loss that valve causes. The scope of application of the present invention Extensively, be used for various vapor line, also can be used for various forms of fluid circuits.
Claims (3)
1. bellow sealed cut-off valve of forming by hand beam [1], valve rod [2], corrugated header [3], bellows [4], semispherical valve [6], valve seat [7], valve gap [8], valve body [9], it is characterized in that: the upper end of bellows [4] and corrugated header [3], the lower end of bellows [4] and semispherical valve [6] are totally-enclosed integrally welded, constitute the whole sealings to valve rod [2].
2. according to the described bellow sealed cut-off valve of claim 1, it is characterized in that the ripple degree of depth h of said bellows [4] is 5mm to 100mm, the pitch of waves L of ripple is 4mm to 120mm.
3. according to the described bellow sealed cut-off valve of claim 1, the radius size that it is characterized in that said semispherical valve [6] is 30mm to 300mm.
