Abstract
The utility model is related to a kind of high temperature and pressure cage type regulating valves, including valve body, valve seat gasket, valve seat, valve cage, spool, valve rod, bonnet gasket, valve deck, it further include baffle, baffle upper end is round, lower end is conically shaped body, it is equipped with the balance hole communicated with conically shaped body at the center of round dignity, several oblique balance holes are equipped at intervals with along the face on balance hole periphery, a circle concave station is equipped in the spool mouth of spool.Baffle is fixed in the concave station of spool lower part.In one baffle of spool lower weld, first, fixed spool lower end, make spool in the case of a high temperature in use, overall deformation is uniform, it will not be stuck with valve cage；Second is that being divided to the high-pressure fluid of entrance, water conservancy diversion, high-pressure fluid will not be made directly to impact valve body lower end, fully ensure that and improve the service life of valve body piece.
Description
Technical field
The utility model is related to a kind of cage type regulating valve, more particularly to a kind of high temperature and pressure cage type regulating valve.
Background technology
The spool of cage type regulating valve is dismountable part in the valve being in direct contact with fluid, for blocking or adjusting Jie
Matter, and can be fitted closely with valve seat, it seals.Therefore the design scheme of spool directly affects the use effect of entire valve
Fruit.
The spool design of traditional high temperature and pressure cage type regulating valve is as shown in figure 5, in high temperature, high pressure occasion in use, outstanding
It is in the prodigious occasion of temperature change, since the design wall thickness of spool parts itself is uneven, leads to spool outer circle dilation dimension
Inconsistent, especially spool lower half portion change in size is very big, it is easy to cause spool stuck with valve cage, cause entire valve not
It can act, influence onsite application, and since high-pressure medium washing away the long-term of valve body lower portion, also affect valve body uses the longevity
Life.
Invention content
In view of the above-mentioned problems of the prior art, the utility model provides a kind of high temperature and pressure cage type regulating valve, spool
Using the structure in lower weld baffle, avoid due to the problem of valve is due to stuck akinesia in hot operation.
To achieve the above object, used technical solution is the utility model：A kind of high temperature and pressure cage type regulating valve, packet
Include valve body, valve seat gasket, valve seat, valve cage, spool, valve rod, bonnet gasket, valve deck；
Valve seat is placed on the valve seat gasket in valve body, and valve cage is packed on the upper surface of valve body inner seat, and spool is packed into valve
In cage, valve deck is fixed on by bonnet gasket on valve body, and valve rod is connect across valve deck with spool；It is characterized in that：Further include leading
Fluid, the baffle upper end are round, and lower end is conically shaped body, are equipped with and conically shaped body phase at the center of round dignity
Logical balance hole is equipped at intervals with several oblique balance holes along the face on balance hole periphery；
A circle concave station is equipped in the spool mouth of the spool；
The baffle is fixed in the concave station of spool lower part.
The utility model has the beneficial effects that：The spool of the utility model is on the basis of traditional valve core, under spool
A baffle is welded in portion, and the effect of baffle mainly has 2, first, fixed spool lower end, makes spool make in the case of a high temperature
Used time, overall deformation is uniform, will not be stuck with valve cage；Second is that being divided to the high-pressure fluid of entrance, water conservancy diversion, high pressure will not be made
Fluid directly impacts valve body lower end, fully ensures that and improve the service life of valve body piece.

Specific implementation mode
The utility model is explained in further detail with specific implementation mode below in conjunction with the accompanying drawings.
As shown in Figures 1 to 4, a kind of high temperature and pressure cage type regulating valve, including valve body 1, valve seat gasket 2, valve seat 3, valve cage
4, spool 5, valve rod 6, bonnet gasket 7, valve deck 8 further include baffle 9.
9 upper end of baffle be round 9-1, lower end be conically shaped body 9-2, at the center in the faces round 9-1 be equipped with
The balance hole 9-3 that conically shaped body 9-2 is communicated is equipped at intervals with several oblique balance hole 9-4 along the face on the peripheries balance hole 9-3.
A circle concave station 5-1 is equipped in the spool mouth of spool 5.
Baffle 9 is embedded in 5 lower part concave station 5-1 of spool, baffle 9 is fixed on spool 5 by welding.
Valve seat 3 is placed on the valve seat gasket 2 in valve body 1, then valve cage 4 is packed into valve body 1 and is placed on valve seat 3
On upper surface, valve rod 6 is connected on spool 5, spool 5, which is packed into valve cage 4, to be packed into valve body, by 8 sets of valve deck valve rod 6 and is led to
It crosses bonnet gasket 7 to be placed on valve body 1, valve deck 8 is pressed on valve body 1 with stud nut, and compress valve seat 3, valve cage simultaneously
4。
