Description
Technical field
The utility model is related to valve technology fields, and in particular to a kind of easy fast safety valve.
Background technology
Safety valve is that opening and closing element is in normally off under by outer force effect, is surpassed when the pressure medium in equipment or pipeline increases
When crossing specified value, by outside system discharge medium come to prevent pressure medium in pipeline or equipment be more than the particular usage valve of specified value
Door.Safety valve belongs to automatic valve class, is mainly used for boiler, on pressure vessels and pipes, and control pressure is no more than specified value, to people
Body safety and equipment have run important protective effect.Note safety valve, which has to pass through pressure testing, to be used.
The place that current safety valve comes with some shortcomings, first, current safety valve all has repair inconvenience, mainly
The reason is that because the sealing ring of the lower valve base of valve body is made of one with lower valve base and can not dismantle, in addition labour cost is high, do not lead to
Parts cause maintenance cost higher than new valve is bought, so safety valve repair at present is cumbersome, difficulty is big.This
The sealing position of class valve once damaged will result in valve fit badly and can not normal use, especially for safety valve come
It says, sealing position, which fits badly, can have prodigious security risk.In addition, more it be stressed that in medium used in current valve
There are many toxic, harmful, mordant medium, the valve almost scrapped at present is all no to pass through relevant technical office
Reason, so the ecological environment to the mankind causes prodigious pollution.
Utility model content
For the defects in the prior art, the utility model provides a kind of easy fast safety valve, to improve safety valve sealing
The replacement speed of position reduces maintenance difficulty, prolongs the service life；The pollution to ecological environment is reduced simultaneously, is improved to environment
Protection.
The utility model provides a kind of easy fast safety valve, including valve body, monomer sealing element and compressing member；The valve body includes
Bonnet, lower valve base and spool；
The bonnet, and lower valve base connect and the top of spool are made to be pressed between bonnet, and lower valve base, the valve
The lower end of core is contacted with the monomer sealing element on the inflow internal diameter boss of lower valve base, and then makes lower end and the list of spool
The structure of the inflow internal diameter of sealing lower valve base is formed between body sealing element；
The compressing member is pressed between the spool and monomer sealing element, described convex for monomer sealing element to be pressed on
On platform.
Preferably, the bonnet, and lower valve base are bolted.Using common bolt fastening, common tool
It can realize the dismounting of bonnet, and lower valve base, reduce dismounting difficulty, facilitate repair.
Preferably, the compressing member is hollow cylinder, and side wall is equipped in through-hole and the discharge of through-hole and lower valve base
Diameter is opposite.Through-hole is set on the side wall of compressing member to make compressing member not block the internal diameter of valve body.
Preferably, gasket is equipped between the monomer sealing element and boss.Gasket improves monomer sealing element under
Leakproofness between valve seat reduces monomer sealing element and is not adjacent to internal diameter boss and causes the probability revealed.
Preferably, the spool is bellows-type Elastic valve core.Bellows-type Elastic valve core acid and alkali-resistance, enables safety valve to fit
Answer various acid or alkali environments.
The beneficial effects of the utility model are embodied in：
The utility model includes valve body, monomer sealing element and compressing member, and the valve body includes bonnet, lower valve base and valve
Core.Wherein monomer sealing element and lower valve base are designed to two components, overcome the sealing ring of the lower valve base of traditional valve body with
Lower valve base is made of one the problem that can not be dismantled, and to allow monomer sealing element to be disassembled from lower valve base, can replace.
Spool contacts or detaches closing and the opening that can realize the utility model with monomer sealing element, and spool can pass through opening
Bonnet, and lower valve base, which are realized, to be replaced, and two positions of spool and monomer sealing element for sealing can be replaced, by long-term
After use, when poorly sealed problem occur in two position abrasions, spool or monomer sealing element or both are replaced simultaneously more
It changes, to solve safety valve repair inconvenience, the big problem of maintenance difficulty.With the monomer sealing element of the easy fast safety valve of model
It is communicated with the specification of spool, to solve the problems, such as that parts are uncurrent, greatly reduces maintenance cost, and repair
Expense is well below the price for buying new safety valve.In addition, only needing replacing monomer sealing element and spool and not having to replace whole
A safety valve reduces the quantity for the safety valve scrapped, and to reduce the pollution to ecological environment, improves the guarantor to environment
Shield.
