Description

Column valve
Technical field
The present invention relates to the pressure valve field, refer in particular to and be applicable to the valve that has leaked partition fully or the runner effect of system of UNICOM in use in electric power and the petroleum and petrochemical industry High Temperature High Pressure pipe-line system anti-.
Technical background
Using a large amount of high-temperature high pressure valves in the High Temperature High Pressure system pipeline in China thermal power generation corporations and petroleum and petrochemical industry, this valve one class is a modulating valve, one class is an isolating valve, in the described isolating valve again based on various brands stop valve, ball valve, the gate valve of domestic and imported.According to customer responsiveness, no matter this type of valve is that import brand or domestic brand all exist interior leakage phenomenon in various degree in the operation using process, at present still do not have any valve to reach to allow the degree of user complete satisfaction, in addition the new valve that has after operation for the first time, promptly occur in the leakage phenomenon; Wherein stop valve exists operational torque big simultaneously, makes problem of difficult processing; It is big that gate valve then exists installation to take up room simultaneously, and actuating length is long, phenomenons such as the easy scratch of sealing surface; Ball valve then exists poorly sealed, and reliability is not high, phenomenons such as maintenance difficult.Shortcoming and defect part at above-mentioned all kinds of valves, again develop a kind of under these abominable working environments of High Temperature High Pressure, can satisfy tight zero leakage requirement, can reach simple in structure again, easy to operate, make easy processing, repair and maintenance is convenient, cost is low, and long high-performance high-temperature high pressure valve of life-span is necessary fully.
Summary of the invention
At the interior leakage phenomenon that existing valve exists, the present invention aims to provide a kind of column valve, and its cocoa satisfies the high-performance of using in the electric power petroleum and petrochemical industry High Temperature High Pressure system, the requirement of the reliable valves of zero leakage.
For achieving the above object, the technical solution adopted in the present invention is: described column valve comprises support, be contained in the valve gap on the support, this valve gap links to each other with middle valve body, its structural feature is, be contained in the lower end of the valve rod in the support and link to each other with cylindrical valve spool in placing valve body, described middle valve body links to each other with right valve barrel with the left valve barrel that is located at both sides respectively; Between described cylindrical valve spool and left valve barrel, be provided with left valve seat, between described cylindrical valve spool and right valve barrel, be provided with right valve seat; Described cylindrical valve spool and left valve barrel together are fastened on left valve seat on the cylindricality sealing surface of cylindrical valve spool and constitute a kind of cylindrical section cambered surface sealing configuration.
Described right valve barrel is that medium flows into end, and left valve barrel is the medium outflow end.Left side valve seat is the cylindricality cambered surface near cylindrical valve spool one side, and right valve seat is the cylindricality plane near cylindrical valve spool one side.
In the present invention, between described left valve barrel and the left valve seat, be equipped with sealing gasket between right valve barrel and the right valve seat.
Described right valve barrel withstands on the cylindricality cambered surface of cylindrical valve spool by the flat end of pressure spring with right valve seat, provides a lasting pretightening force to the sealing surface of cylindrical valve spool and left valve seat.
Described valve gap is provided with Gland, and this Gland passes through the filler gland with in the space of packing seal between valve gap and valve rod.
Further, the sealing surface of described cylindrical valve spool is whole cylindricality arc surfaces, and its inner runner is circular.
The sealing surface of described left valve seat is a part cylindricality cambered surface, and its inner runner is circular; The end face of right valve seat is the cylindricality plane, and its inner runner is circular.
Described valve gap and support by bolton on middle valve body.Described left valve seat and right valve seat are respectively by being bolted to middle two ends of valve body.
Compare with the existing all kinds of valves that are used under the job family environment, the invention has the beneficial effects as follows:
1, the sealed precision of cylindrical valve spool and left valve seat, right valve seat and sealability obtain maximized raising, can not cause the such small number of operations number of times of ball valve the situation of uncertain leakage promptly to occur;
2, the operational torque of valve reduces greatly, is far smaller than the operational torque of stop valve stopcock, and act of operation is fast rapid, only needs 90 ° of rotational valve cores promptly to finish the shutoff or the unlatching of valve;
3, the repair and maintenance of valve is convenient, quick, can the online maintenance of finishing rapidly valve;
4, Sealing can a whole set of be changed, and has reduced cost, alleviates workload, prolongs valve working life greatly.

Embodiment
Further set forth the present invention below in conjunction with accompanying drawing, and provide the embodiment of the invention.
Wherein Fig. 1 provides, and to be the present invention be the embodiment of sealing surface with cemented carbide, and described column valve comprises transmission device 19, support 18, valve rod 17, valve gap 9, middle valve body 5, left valve barrel 1, right valve barrel 8, cylindrical valve spool 4, left valve seat 3, right valve seat 6, spring 7, bolt 2,13,16, Gland 12, filler gland 11, sealing gasket 14, filler 10.The valve of showing among Fig. 1 is a fully open position, and medium flows into from right valve barrel 8, flows out from left valve barrel 1.
When transmission device 19 clockwise direction rotating band ovable valve stems 17 rotated, the cylindrical valve spool 4 that links to each other with valve rod 17 was also along with valve rod 17 moves in the direction of the clock simultaneously.Originally and the runner on the cylindrical valve spool 4 that connects fully of left valve barrel 1 right valve barrel 8 and cylindricality left side valve seat 3 movable right valve seats 6 progressively misplace with above-mentioned runner thereupon.When valve rod 17 is finished 90 ° of whens rotation, the runner of cylindrical valve spool 4 has also rotated 90 ° and has disconnected fully with valve flowing channel.At this moment, tight fully applying of cylindrical section arc sealing surface on the pillar arc sealing surface of cylindrical valve spool 4 and the pillar left side valve seat 3, be delivered in sealing force on the sealing surface except being compressed by spring 7 elastic force that forms, the internal system pressure that also has the medium that flows into from right valve barrel 8 to bring.With cylindrical valve spool 4 being pressed on the valve seat 3 of a cylindricality left side tightly, form tight seal, at this moment, as shown in Figure 2, valve is finished complete closing operation.Otherwise it is omnidistance that the overall process of valve opening then is a said process.
For improve column valve of the present invention high temperature resistant, resistance to wear, scour resistance, left and right valve seat and cylindrical valve spool all can adopt whole special engineering ceramic making, its sealing surface adopts cemented carbide to make.
