Description
Technical field
The utility model is related to a kind of blow valves, and in particular to a kind of dead-weight steam evacuation valve.
Background technology
At present, the valve group in common heating furnace vacuum valve is in same phase space, the associated mechanicals such as counterweight, mandrel with counterweight
Component is chronically in steam immersion status, easily occurs corrosion and ageing, it is poorly sealed the defects of.
Utility model content
The purpose of this utility model is：A kind of dead-weight steam evacuation valve is provided, can be realized valve group and upper strata counterweight
It is spatially separating, reduces corrosion and ageing speed, improve whole service life.
The technical solution of the utility model is：A kind of dead-weight steam evacuation valve, including what is placed on valve seat and valve seat
Housing, the jacket internal are equipped with axle sleeve, and backing plate is cased with outside the axle sleeve, and the counterweight that jacket internal is divided into top by backing plate is empty
Between and lower part the vapor space, be placed with counterweight above the backing plate, the axle sleeve bottom is also associated with spool, and seat bottom portion is set
There is steam inlet, when steam evacuation is not required, the spool is sitting on steam inlet, and the housing lower part is equipped with steam (vapor) outlet.
The valve core outer surface is equipped with leather cup.
Cover board is equipped at the top of the housing, mandrel is housed inside the axle sleeve, the mandrel top-hung is on the cover board.
The backing plate and spool are connected respectively with sleeve thread.
The counterweight center is equipped with hole, and counterweight is sleeved on by the hole on axle sleeve.
The steam inlet and steam (vapor) outlet are respectively equipped with flange.
The beneficial effects of the utility model：
This dead-weight steam evacuation valve arrangement provided by the utility model is simple, can realize that the vapor space is empty with counterweight
Between separate, reduce upper strata space mechanism part corrosion, prolong the service life.
The utility model is described in further details below with reference to attached drawing.

Specific embodiment
Embodiment 1：
A kind of dead-weight steam evacuation valve as shown in Figure 1 is present embodiments provided, including being put on valve seat 8 and valve seat 8
The housing 2 put, the housing 2 are internally provided with axle sleeve 5, and backing plate 6 is cased with outside the axle sleeve 5, and backing plate 6 will be divided into inside housing 2
The counterweight space on top and the vapor space of lower part, 6 top of backing plate are placed with counterweight 3, and 5 bottom of axle sleeve is also associated with
Spool 7,8 bottom of valve seat are equipped with steam inlet 9, and when steam evacuation is not required, the spool 7 is sitting on steam inlet 9, described outer
2 lower parts are covered equipped with steam (vapor) outlet 10.
The operation principle of this dead-weight steam evacuation valve provided by the utility model is as follows：
Pressure as needed places counterweight, and when steam evacuation is not required, spool 7 is sitting on steam inlet 9, when steam is put
When empty, spool 7 moves up under the pressure of steam, and steam inlet 9 is opened, and steam is escaped by steam (vapor) outlet 10, realizes emptying.
This dead-weight steam evacuation valve arrangement provided by the utility model is simple, can realize that the vapor space is empty with counterweight
Between separate, reduce upper strata space mechanism part corrosion, prolong the service life.
Embodiment 2：
On the basis of embodiment 1, this dead-weight steam evacuation valve provided in this embodiment, 7 outer surface of spool
Equipped with leather cup, when steam evacuation is not required, spool 7 is sitting on steam inlet 9, and the setting of leather cup improves sealing effect.
Embodiment 3：
On the basis of embodiment 1, this dead-weight steam evacuation valve provided in this embodiment, 2 top of housing is set
There is cover board 1,5 inside of axle sleeve is equipped with mandrel 4, and for 4 top-hung of mandrel on cover board 1,3 center of counterweight is equipped with hole,
Counterweight 3 is sleeved on by the hole on axle sleeve 5, facilitates the addition and taking-up of counterweight.
Further, for the ease of assembly and disassembly, the backing plate 6 and spool 7 are threadedly coupled respectively with axle sleeve 5.
Embodiment 4：
On the basis of embodiment 1, this dead-weight steam evacuation valve provided in this embodiment, 9 He of steam inlet
Steam (vapor) outlet 10 is respectively equipped with flange, easy assembly and disassembly.
Exemplified as above is only for example, not forming to the scope of protection of the utility model to the utility model
Limitation, it is every to be belonged to the same or similar design of the utility model within the scope of protection of the utility model.
