Description
Technical field
The utility model belongs to sealing valve technical field, more particularly, to a kind of noise cancelling type all-closed horizontal pressure reducing valve.
Background technique
Pressure reducing valve is widely used as a kind of regular industrial with valve, and in blast furnace gas, reducer unit is installed in height
Producer gas enters the position of gaspipe network, for adjusting furnace top pressure, to guarantee the normal operating smelted, so being subjected to furnace roof
Pressure must not be revealed.The structure of reducer unit is with the combination of several butterfly valves by adjusting opening degree tune in blast furnace gas at present
Valve front and back pressure difference is saved, this structure is generally existing to be not closed completely, and inside lets out leakage and adjusts the noise that inaccurate and valve group goes out one's intention as revealed in what one says
The disadvantages such as larger.
Summary of the invention
The purpose of the utility model is to provide one kind can fundamentally prevent valve body be not closed completely, it is interior let out leakage, adjust
The noise cancelling type all-closed horizontal pressure reducing valve for the problems such as inaccuracy and noise are larger.
The purpose of this utility model is realized by following technical proposals:
The noise cancelling type all-closed horizontal pressure reducing valve of the utility model, including the transmission shaft inside decompression piece housing is arranged in,
The clock valve core of this transmission shaft end point is set, the valve seat being fixedly connected with the decompression piece housing, it is characterised in that in institute
The outside for stating decompression piece housing inner cavity is provided with centering guiding combination, in the decompression piece housing end and is located at the transmission shaft
End is equipped with seal combination, is connected with FlexbleJoint, axial sealing compensation adjustment group in turn with the decompression piece housing end
It closes and anechoic chamber, the axial sealing compensation adjustment combination is connected with the valve seat.
The anechoic chamber is the seal chamber soundproof room of tapered opening.
It is equipped in the FlexbleJoint and adjusts bolt.
The advantages of the utility model:
(1) the noise cancelling type all-closed horizontal pressure reducing valve of the utility model is adjusted axially using single valve opening degree instead of original more
A butterfly valve parallel connection adjustment structure, driven journal all seal, and fundamentally prevent spindle nose and leak problem；
(2) the noise cancelling type all-closed horizontal pressure reducing valve of the utility model replaces butterfly valve using clock valve and fills with the centering of valve seat
It sets, makes to seal relatively reliable, avoid gas leak and adjust the disadvantages such as inaccuracy；
(3) the noise cancelling type all-closed horizontal pressure reducing valve of the utility model is provided with anechoic chamber after valve, enters in Gas Flow
First noise reduction is carried out before muffler, it can noise reduction 20db -30db；
(4) the noise cancelling type all-closed horizontal pressure reducing valve of the utility model, structure is simple, convenient disassembly, as long as unclamping ripple
The adjusting bolt of compensator, so that it may by clock valve return and sling the adjustment combination of Zhongxiang City's sealing compensation, make to replace clock valve and valve seat is non-
It is often convenient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Specific embodiment of the present utility model is further illustrated with reference to the accompanying drawing.
As shown in Figure 1, the noise cancelling type all-closed horizontal pressure reducing valve of the utility model, including setting is in decompression piece housing 1
The clock valve core 9 of this 2 end point of transmission shaft is arranged in the transmission shaft 2 in portion, the valve seat being fixedly connected with the decompression piece housing 1
4, it is characterised in that be provided in the outside of decompression 1 inner cavity of piece housing to middle guiding combination 6, in the decompression piece housing 1
End and be located at 2 end of transmission shaft be equipped with seal combination 3, with 1 end of decompression piece housing be connected in turn ripple benefit
Repay device 7, axial sealing compensation adjustment combination 5 and anechoic chamber 8, the axial sealing compensation adjustment combination 5 and the valve seat 4
It is connected.
The anechoic chamber 8 is the seal chamber soundproof room of tapered opening.
It is equipped in the FlexbleJoint 7 and adjusts bolt.
Depressurize the transmission shaft 2 and clock valve core 9 of fixed valve body in piece housing 1；The spindle nose bar of valve body transmission shaft 2 is by being fixed on
The seal combination 3 of 1 end of piece housing is depressurized to realize dynamic sealing；The clock valve core 9 for being fixed on 2 one end of transmission shaft moves forward directly
To contact valve seat 4, in-between process is pressure regulation section；Clock valve core 9 is moved horizontally to rely on and is fixed on outside decompression 1 inner cavity of piece housing
Stable linear motion is completed in 6 support of centering guiding combination in portion；Axial sealing compensation adjustment combination 5 passes through FlexbleJoint 7
It is connect with decompression piece housing 1, and compresses and seal with the inner cone of anechoic chamber 8 behind, guarantee anechoic chamber 8 and axial seal
Compensation adjustment combination 5 forms the outer cavity space of an independent closed sound insulation.
The utility model is adjusted axially using single valve opening degree instead of original multiple butterfly valve parallel connection adjustment structures, transmission shaft 2
End all seals, and fundamentally prevents spindle nose and leaks problem；Secondly, replacing butterfly valve using clock valve and making with valve seat centralising device
It seals relatively reliable, avoids gas leak and adjust the disadvantages such as inaccuracy；In addition, anechoic chamber 8 is provided with after valve, it can noise reduction
20 db—30db.Furthermore clock valve return can be sling axial sealing compensation adjustment by the adjusting bolt for unclamping FlexbleJoint 7
Combination 5, replaces clock valve core 9 and valve seat 4 is all very convenient.
