Abstract
The invention relates to a switch valve applicable to a transmission pipeline, and specifically relates to a labyrinth valve. The labyrinth valve comprises a valve body, a valve seat and a valve element, wherein one end of each of two sides of the valve body is provided with an inlet, and the other end of each of the two sides of the valve body is provided with an outlet; the valve seat is arranged at the bottom part of the valve body; an empty chamber is formed in the valve body; an opening where a valve cover sealing opening is arranged is formed in the top end of the valve body; the valve element is mounted in the valve body; sealing teeth are arranged at the end, adjacent to the valve seat, of the valve element; vertical sealing teeth which are engaged with each other are arranged in the side surface, adjacent to the valve body, of the valve element; the valve element is connected with a valve rod which is mounted on the valve cover in a connecting manner; the top end of the valve rod extends out of the outer part of the valve cover through a mounting hole; the tail part of the valve rod can be pulled to drive the valve element to move. According to the labyrinth valve, no friction is generated between the valve element and the valve seat, so that the loss of the valve element can be avoided, and as a result, the service life of the valve can be prolonged; meanwhile, the labyrinth type intercepting effect is utilized to realize good intercepting and leaking resisting effect.
Description
Technical field
The present invention relates to a kind of controlled valve in transmission pipeline, specially labyrinth type valve.
Background technology
Valve is the effect that cut-off, regulated fluid transmission are reached by switching spool.Existing regular tap valve, adopts
Contact is sealed firmly, i.e., close when valve element is in close contact with valve seat, open during separation.Contact valve is long due to valve element and valve body
Phase is in close contact, and open and close can produce friction, and part is easily lost, and causes service life short, poorly sealed, easily reveals
The problems such as.
The content of the invention
It is short, poorly sealed in order to solve the problems, such as contact valve service life, a kind of labyrinth type valve is devised, is adopted
Contactless structure, it is to avoid friction, reduce loss.
Labyrinth type valve, including valve body, valve seat and valve element, valve body both sides one end arrange import, and the other end is arranged out
Mouthful, body base arranges valve seat.Valve inner is cavity, and top end opening, setting valve gap closing opening at opening, valve element are arranged on
In valve body；The valve element and valve seat abutting end are provided with sealing tooth, and the valve element and valve body adjacent side are provided with what is be meshed
Vertical sealing tooth.The valve element is connected with valve rod, and valve rod is installed on connection valve lid, and valve stem tip is stretched out outside valve gap from installing hole
Portion, can pull valve rod afterbody, drive valve core movement.
Further, there is gap between the tooth bar of the sealing tooth, forms expansion cavity.The tooth of the vertical sealing tooth
There is between bar gap, expansion cavity is formed.Between tooth and tooth and not in contact with that is, valve element and valve base chamber have gap, will not produce
Raw frictional dissipation.Continuous multiple cavitys are formed between multiple tooth bars, labyrinth effect is constituted, convection cell is played and dammed between tooth bar
Effect, fluid when by tortuous labyrinth teeth interspace produces throttle effect, reaches the purpose of Drain Resistance.Simultaneously at a high speed
Fluid stream is fashionable, circles round, the kinetic energy of fluid is converted into heat energy, by valve heat loss through conduction in expansion cavity.Tooth and tooth it
Between can also adopt contact, it is closely adjacent, as valve element is to move up and down, valve opening or when closing, valve element and valve seat it
Between will not also produce friction.
The further valve element is provided with inside groove, groove with valve rod connecting portion and places airtight and watertight padding, sealing
Valve body, prevents from revealing.Described airtight and watertight padding is liquid, flour or both compounding substances, or is with lubrication
Solidss.
The further valve rod is located on the bar in valve body and is provided with limiting card, prevents valve rod from entirely taking off from valve body
From.
Labyrinth type valve, does not produce friction, it is to avoid the loss of valve element between valve element and valve seat, extend the use longevity of valve
Life, while damming effect using labyrinth type, can play Drain Resistance effect of damming well.

Specific embodiment
With reference to specific embodiment and Figure of description, the invention will be further described.Concrete reality described herein
Example is applied only to explain the present invention, is not intended to limit the present invention.
Embodiment：As shown in Figure 1 and Figure 2, labyrinth type valve, is made up of valve body 1, valve seat 2, valve element 3, valve rod 4 and valve gap 5.
The valve body 1 is cavity, and 1 bottom of valve body arranges valve seat 2, the setting import 11 of 1 bottom end of valve body, other end setting outlet 12.
1 top end opening of valve body, arranges the closing opening of valve gap 5 at opening, install valve element 3 and valve rod 4, valve in valve body 1 from bottom to up successively
Core 3 is connected with valve rod 4.Valve rod 4 is installed on connection valve gap 5, and 4 top of valve rod is stretched out outside valve gap 5 from installing hole.
4 top of valve rod arranges valve bonnet 42.Valve bonnet 42 is arranged on valve gap 5, and the connection valve rod 4 of spring 43 is arranged in valve bonnet 42.
4 top of valve rod is also associated with an action bars 44, for being lifted up valve rod 4.The valve rod 4 is located on the bar in valve body and arranges
Limited location card 41, prevents valve rod from entirely departing from from valve body.
The valve element 3 and 2 abutting end of valve seat are respectively arranged with the sealing tooth 6 being meshed.As shown in figure 3,3 He of the valve element
1 adjacent side of valve body is respectively arranged with the vertical sealing tooth 7 being meshed.Can not contact between tooth and tooth, there is certain interval,
Labyrinth type expansion cavity is formed, the effect of damming is reached；Or be in close contact between tooth and tooth, also can reach the effect of damming.
The valve element 3 is provided with inside groove 8, groove with 4 connecting portion of valve rod and places airtight and watertight padding 81, and described is close
Packing material is oily matter, flour or both compounding substances, or is the solidss with lubrication, sealed valve body,
Prevent from revealing.
As shown in figure 1, when labyrinth type valve is not switched on, valve element 3 is adjacent with valve seat 2, the tooth and between cog for sealing tooth 6 constitutes swollen
Swollen cavity, the tooth of vertical sealing tooth 7 also constitute expansion cavity between cog, form labyrinth type valve, play the effect of damming, anti-stopping leak
Dew.As shown in Fig. 2 being lifted up valve rod 4, valve element 3 is ramped up simultaneously, and valve element 3 becomes big with the spacing of valve seat 2, valve opening.
No matter labyrinth type valve, be turned on and off state, can avoid frictional dissipation, greatly prolong between valve element and valve seat
The service life of valve.
It is preferred embodiments of the present invention in sum, all changes made according to technical solution of the present invention, the work(for being produced
Protection scope of the present invention is belonged to when can act on the scope without departing from technical solution of the present invention.
