Description
Technical field
The utility model relates to valve technology fields, and in particular to a kind of pressure charging valve.
Background technique
Existing to store some chemical substances using the warehouse sealed, warehouse is during carrying out use, in warehouse
Pressure can be gradually reduced, and will affect the quality for the chemical substance stored in warehouse when the pressure in warehouse declines excessive, therefore
It needs to be adjusted by pressure of the pressure charging valve to warehouse, improves the pressure in warehouse to protect chemical substance.
Existing pressure charging valve there is a problem of following during use:
1, breakdown action is insensitive, and relief pressure value cannot be adjusted accurately, and product is heavy；
2, when in warehouse pressure also in safety value when will appear leakage, thus pollute environment and increase raw material loss.
Utility model content
For the deficiency in the presence of the prior art, the purpose of this utility model is to provide a kind of pressure charging valves, to solve
In the prior art, when the pressure in warehouse changes, pressure charging valve breakdown action is insensitive, and relief pressure value cannot be adjusted accurately
Section, product is heavy and the problem of leakage is easy to happen in safety value.
To achieve the above object, the utility model uses the following technical solution: a kind of pressure charging valve, including valve body, institute
It states and is provided with relief hole at the top of valve body, valve body is equipped with the bonnet assemblies being sealed to relief hole, bonnet assemblies cooperation
It is provided with the adjustable fixation kit of required pressure value when control relief hole is in connected state；
The bonnet assemblies include the valve deck of valve inner is sealed and is placed in relief hole and is carried out in valve body,
The inner wall sliding contact of the frame body of lower slider, frame body and valve body, is connected between frame body and valve deck by guide rod.
Compared with the prior art, the utility model has the following beneficial effects:
1, the unlatching value of this pressure charging valve is regulated by adjustable fixation kit, convenient for setting different unlatching values, and is adjusted
Accurately；When the intracorporal pressure of valve is more than the unlatching value of setting during reduction, extraneous pressure is greater than valve inner
Pressure drives valve deck slide downward in valve body, and relief hole is in the state of connection, and extraneous air enters in valve body, makes valve
Intracorporal pressure increases；Valve deck is supported and is oriented to by frame body and guide rod simultaneously, this pressure charging valve is improved and was opening
Sensitivity in journey；
2, this pressure charging valve includes the structures such as valve body, adjustable fixation kit, frame body, valve deck and guide rod, keeps its structure slim and graceful,
The work such as it is easily installed, dismantles or moves；And the unlatching value of this pressure charging valve is regulated by adjustable fixation kit, it will not be in safety
It opens and leaks in value, leakproofness is good, if this pressure charging valve is applied to warehouse, reduces the pollution to environment, reduces
The loss of raw material.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail below by specific embodiment:
Appended drawing reference in Figure of description includes: valve body 1, upper valve body portion 101, upper cover part 102, relief hole 2, valve deck

Second connecting rod 10.
Embodiment
Referring to fig. 1 and fig. 2: a kind of pressure charging valve, including valve body 1, the top of valve body 1 are provided with relief hole 2, and valve body 1 is matched
Conjunction is provided with 3 component of valve deck being sealed to relief hole 2, and 3 component of valve deck is equipped with control relief hole 2 and is in connected state
The adjustable fixation kit of required pressure value when state；3 component of valve deck includes being sealed and being placed in inside valve body 1 to relief hole 2
Valve deck 3 and the frame body 4 that is slided above and below in valve body 1, the inner wall sliding contact of frame body 4 and valve body 1, frame body 4 and valve deck
It is connected between 3 by guide rod 5.
In order to further increase the sealing performance of relief hole 2,3 component of valve deck further includes along 3 top surface edge of valve deck in week
It to the ring packing silicone rubber pad 6 of arrangement, fits closely valve deck 3 to the top of valve body 1, improves pressure charging valve to reach
The purpose of leakproofness；And valve body 1 includes upper valve body 1 and the upper cover part 102 that 1 top of lower valve body is arranged in, upper cover part 102 is logical
It crosses multiple locking members to be fixedly linked with upper valve body 1, multiple locking members are in circumferentially along the top surface edge of upper cover part 102；
Locking member can be bolt, and the structure of valve body 1 is convenient for when 1 internal structure of valve body goes wrong, is carried out quickly to valve body 1
Disassembly after repair its internal structure；The arrangement of locking member is in order to improve the bonding strength of valve body 1.
In order to improve the structural strength of frame body 4, frame body 4 include with the toroidal frame 401 of the inner wall sliding contact of valve body 1 and
It is in multiple connecting rods 402 of interlaced arrangement on the inside of toroidal frame 401, multiple connecting rods 402 form grid structure；Pass through toroidal frame
401 make the inner wall sliding contact of frame body 4 Yu valve body 1, improve the performance of its sliding contact, avoid the occurrence of the state to offset, simultaneously
Grid structure is formed to enhance the structural strength of frame body 4 by multiple connecting rods 402, and it is strong to the support of valve deck 3 to improve frame body 4
