Description
Technical field
The utility model belongs to valve technology field, more particularly to a kind of regulating valve with valve element protective case.
Background technology
Existing regulating valve generally has Flow-rate adjustment and closing function, and the Flow-rate adjustment of regulating valve and closing simultaneously
Function is realized by valve element, but fluid, during regulating valve is flowed through, fluid is directly flushed on valve element, right
The sealing surface of valve element causes to wash away, and easily causes regulating valve to occur poorly sealed situation after closing.
Utility model content
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of tune with valve element protective case
Save valve.The regulating valve is provided with valve element protective case in valve element outer sheath and directly washes away valve element for avoiding fluid, so as to reduce
The possibility that valve element is corroded by fluid scouring, extend the service life of the regulating valve.
The purpose of this utility model is achieved through the following technical solutions：
A kind of regulating valve with valve element protective case, including valve body, valve seat, bonnet, valve rod and valve element, the valve element are located at
In valve body, the lower end of the valve rod is stretched in valve body through bonnet to be connected with valve element, and the valve element outer sheath is protected provided with valve element
Sheath, the upper end of the valve element protective case are connected by the upper end of spring and valve element.
When the regulating valve is in open mode, under the action of the spring, the lower end of valve element protective case is low for valve element protective case
In the lower end of valve element, the regulation of flow is realized by valve element protective case.And valve element protective case carries out certain to valve element
Block, avoid fluid from directly washing away valve element, so as to reduce the possibility that valve element is corroded by fluid scouring, ensured the regulation
The sealing property of valve, extend the service life of the regulating valve.
When closing the regulating valve, valve element is descending, and valve element protective case contacts valve seat first, and valve element continues traveling downwardly, spring quilt
Compression, valve element contact with valve seat, realize the closing of regulating valve.
Preferably, the outer sheath of the valve element protective case is provided with flow sleeve, and the flow sleeve is provided with multiple for flowing
The through hole that body passes through.
After fluid enters valve body, the through hole first passed through on flow sleeve is reached at valve element again, and because through hole is smaller, fluid need to be from
The through hole of flow sleeve surrounding is by avoiding fluid from directly reaching at valve element and caused imperfect flow, improving the regulation
The degree of accuracy of valve Flow-rate adjustment.
Preferably, the lower end of the valve element lateral surface is provided with the first sealing ring, and the upper end of the valve seat medial surface is provided with the
Two sealing rings.
When valve is closed, the first sealing ring and the second sealing ring are engaged, for improving the sealing when regulating valve is closed
Performance.
Preferably, airtight and watertight padding is filled between the valve rod and bonnet.
Airtight and watertight padding is filled between valve rod and bonnet, for avoiding fluid from being leaked out along the gap between valve rod and bonnet
The regulating valve.
Preferably, the top of the bonnet is provided with follower.
Follower is used to compress airtight and watertight padding, to improve the sealing property of airtight and watertight padding.
The beneficial effects of the utility model are：The regulating valve is provided with valve element protective case in valve element outer sheath, the regulating valve
Flow-rate adjustment and closing function are separated, and the flow regulating function of the regulating valve is come by moving up and down for valve element protective case
Realize, the closing function of the regulating valve fits to realize by valve element with valve seat.Such set-up mode avoids
Fluid directly washes away valve element, reduces the possibility that valve element is corroded by fluid scouring, extends the service life of the regulating valve.

In Fig. 1：1 is valve element, and 2 be valve element protective case, and 3 be valve body, and 4 be flow sleeve, and 5 be valve rod, and 6 be bonnet, and 7 be close
Packing material, 8 be follower, and 9 be valve seat, and 10 be the first sealing ring, and 11 be the second sealing ring, and 12 be spring, and 13 be through hole.
Embodiment
Below in conjunction with the accompanying drawings with specific case study on implementation come have to the utility model the regulating valve of valve element protective case do into
One step elaborates, and in the hope of being more fully apparent from expresses architectural feature and concrete application of the present utility model, but can not be with
This limits the scope of protection of the utility model.
Embodiment：As shown in figure 1, a kind of regulating valve with valve element protective case, including valve body 3, valve seat 9, bonnet 6, valve
Bar 5 and valve element 1, the valve element 1 are located in valve body 3, and the lower end of the valve rod 5 is stretched to through bonnet 6 in valve body 3 and valve element 1
Connection, the outer sheath of valve element 1 are provided with valve element protective case 2, and the upper end of the valve element protective case 2 passes through the upper end of spring 12 and valve element 1
Connection.
The outer sheath of valve element protective case described in the present embodiment 2 is provided with flow sleeve 4, and valve element 1 and valve element protective case 2 are in valve
