Description
Technical field
The utility model relates to a kind of valve, particularly a kind of anti-blocking valve.
Background technique
The process units such as caprolactam, fusing urea, melamine all have crystallization processes flow process.Due to the full-bore Flow characteristics of ball valve, structure simply, closely reliable, easy to operate, opening and closing is rapid, the feature such as applied widely, in crystallization processes flow process, the normal soft sealing ball valve that adopts is as blocking use.But soft sealing ball valve is very short for working life, normally valve will be changed 2 ~ March.Main cause is that easy crystal medium is easily deposited in valve cavity, along with the accumulation of service time, easy crystal medium is by spheroid locking, cause valve cannot action, during Open valve, soft seal valve seat often damages loss of seal performance by force, brings very large puzzlement to the long period of device, reliable operation.
Model utility content
The purpose of this utility model is to provide a kind of energy-saving prevention block valve, to solve the problems of the technologies described above.
The technical problem that the utility model solves can realize by the following technical solutions:
Energy-saving prevention block valve, comprises a valve body, and described valve body comprises a valve flowing channel and a sprue, described sprue is provided with a water inlet and a water outlet, it is characterized in that, described valve flowing channel tilts, and described valve flowing channel and described sprue are the angle between 40 degree to 50 degree;
Also comprise a flap, described flap is connected with valve rod, and the described flap width of connecting end is greater than described water inlet width, and the front end of described flap is less than the width of described water inlet.Under the effect of hydrodynamic pressure, easy crystal medium can not be bonded on described flap.Described valve body is Y type, thus the destructiveness of medium under flowing state is reduced, and realizes energy-conserving and environment-protective requirement.
Described valve rod is connected with Anti-rotary block bolt, and described Anti-rotary block connects a fixing rod, and described fixing rod one end connects valve gap, the other end connection bracket, assembling Stem Mut in described support, described Stem Mut and described valve rod adopt trapezoidal thread to be connected, and described Stem Mut connects an actuator.So that described Anti-rotary block makes described valve rod moving linearly all the time, ensure the stability that described valve rod opens and closes up and down, the hard sealing surface contact position of described flap and described valve body does not change, and keeps sealing effect for a long time.
Described valve gap and described valve body adopt bolt and spirotallic gasket to realize being tightly connected.Guarantee the sealing of described valve body.
Be provided with a stuffing box in described valve flowing channel, described stuffing box is connected with valve gap, and described stuffing box is concordant with valve outlet runner.The action making easy crystal medium can not be deposited in described body cavity to block described flap.
Described valve rod and described stuffing box contacting point are provided with an annular packing mouth, and the described feeding port degree of depth is no more than 30% of described stuffing box length.Ensure the fluency of described valve body work.
The sealing surface of described flap and described valve body all adopts special superpressed process.When described flap contacts with the hard sealing surface of described valve body, the easy crystal medium be bonded on sealing surface can be pulverized and to be taken away by high-velocity fluid pressure afterwards, ensure the long term seal effect of described energy-saving prevention block valve, effectively extend the working life of described energy-saving prevention block valve.
Accompanying drawing explanation
Fig. 1 is sectional structure chart of the present utility model.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, setting forth the utility model further below in conjunction with concrete diagram.
As shown in Figure 1, energy-saving prevention block valve, comprises a valve body 1, and valve body 1 comprises a valve flowing channel and a sprue, and sprue is provided with a water inlet and a water outlet, and valve flowing channel tilts, and valve flowing channel and sprue are the angle between 40 degree to 50 degree.Valve body 1 in Y type, thus makes the destructiveness of medium under flowing state reduce, and realizes energy-conserving and environment-protective requirement.
Also comprise a flap 2, flap 2 is connected with valve rod 3, and flap 2 width of connecting end is greater than water inlet width, and the front end of flap 2 is less than the width of water inlet.Under the effect of hydrodynamic pressure, easy crystal medium can not be bonded on flap 2.
Valve rod 3 is connected with Anti-rotary block 7 bolt, and Anti-rotary block 7 connects a fixing rod, and fixing rod one end connects valve gap 6, the other end connection bracket 8, assembling Stem Mut 9 in support 8, Stem Mut 9 adopts trapezoidal thread to be connected with valve rod 3, and Stem Mut 9 connects an actuator 10.So that Anti-rotary block 7 makes valve rod moving linearly all the time, ensure the stability that valve rod about 3 opens and closes, the hard sealing surface contact position of flap 2 and valve body 1 does not change, and keeps sealing effect for a long time.
The sealing surface of flap 2 and valve body 1 is all through special superpressed process, when flap 2 contacts with the hard sealing surface of valve body 1, the easy crystal medium be bonded on sealing surface can be pulverized and to be taken away by high-velocity fluid pressure afterwards, ensure the long term seal effect of valve, the longevity effectively extending valve uses the life-span.
Valve rod 3 adopts to be threaded with flap 2 and is welded and fixed, and effectively reduces valve rod 3 and flap 2 joint gap.
The stuffing box 4 extended gets involved valve body 1 inner chamber and concordant with valve body 1 outlet flow, the action making easy crystal medium can not be deposited in body cavity to block flap 2.
Filler 5 adopts combined sealing structure, ensures that valve rod place is without external leakage.
Valve gap 6 and valve body 1 adopt bolt and spirotallic gasket to realize sealing, and ensure without external leakage.
Anti-rotary block 7 makes valve rod 3 moving linearly all the time, and ensure the stability that valve rod about 3 opens and closes, the hard sealing surface contact position of flap 2 and valve body 1 does not change, and keeps sealing effect for a long time.
Assembling Stem Mut 9 in support 8, Stem Mut 9 adopts trapezoidal thread to be connected with valve rod 3, and actuator 10 drives Stem Mut 9 to rotate, thus band ovable valve stem 3 moves up and down as straight line, realizes the keying function of valve.
