Description
Technical field
The utility model belongs to controlled valve technical field, and in particular to a kind of antivoid valve.
Background technology
Antivoid valve is for protecting the working equipment of operation under vacuum conditions, when vacuum exceedes the limit of setting
During value, working equipment is difficult to bear excessive pressure, then needs by being provided with antivoid valve, pressure mistake in pipe-line system
When big, then pressure is discharged by antivoid valve, so as to protect working equipment.But existing antivoid valve, it is complicated,
Assembly process is more, and sealing is easy to decline with the passage of usage time.
Utility model content
The purpose of this utility model is：For problems of the prior art, there is provided a kind of antivoid valve, structure
Simply, it is easy to assembly, and good airproof performance.
To achieve these goals, the technical solution adopted in the utility model is：
A kind of antivoid valve, including valve body, bonnet, valve top, spring base, valve rod, spring and adjusting screw rod, valve body and valve
Lid is fixedly connected, and cavity and the access way of connection cavity are provided with valve body, porus excretorius is provided with the wall of cavity surrounding,
Valve top is arranged in the cavity of valve body and for opening or closing the access way；Described adjusting screw rod through bonnet and with
Bonnet is threadedly coupled, and passes through described valve rod in adjusting screw rod, valve rod one end withstands on valve top back and had in the end set
Described spring base, described spring is arranged with valve rod, and spring is between spring base and adjusting screw rod；
Seal face on the valve top being in contact with valve body is provided with dovetail annular groove, and sealing ring is provided with dovetail annular groove.
Preferably, be arranged with the clamp ring for adjusting screw rod being fixed on bonnet on described adjusting screw rod, and
Cap body is arranged with adjusting screw rod, cap body is threadedly coupled with bonnet.
Preferably, described sealing ring is O-ring seals.
By adopting the above-described technical solution, the beneficial effects of the utility model are：
A kind of antivoid valve of the present utility model, by the knot that dovetail groove is provided with the sealing surface on valve top and valve body
Structure, easy to assembly for placing sealing ring, technique is simple, effectively sealing ring can be wrapped in groove, and pressure is higher
When, sealing effectiveness is more preferable, while can effectively place coming off for sealing ring.
Brief description of the drawings
Fig. 1 is antivoid valve front sectional view of the present utility model.
Fig. 2 is Fig. 1 A portions enlarged drawing.
Reference：1- valve bodies, 2- sealing rings, 3- valves top, 4- spring bases, 5- springs, 6- valve rods, 10- bonnets, 11- are adjusted
Save screw rod, 12- cap bodies, 13- clamp rings, 14- dovetail annular grooves.
Embodiment
Reference picture 1, Fig. 2, antivoid valve of the present utility model, including valve body 1, bonnet 10, valve top 3, spring base 4, valve
Bar 6, spring 5 and adjusting screw rod 11, valve body 1 are fixedly connected with bonnet 10, and entering for cavity and connection cavity is provided with valve body 1
Go out passage, porus excretorius is provided with the wall of cavity surrounding, valve top 3 is arranged in the cavity of valve body 1 and for opening or closing institute
State access way；Described adjusting screw rod 11 is threadedly coupled through bonnet 10 and with bonnet 10, through described in adjusting screw rod 11
Valve rod 6, the one end of valve rod 6 withstands on the back of valve top 3 and has described spring base 4 in the end set, is arranged on valve rod 6
The spring 5 stated, and spring 5 is between spring base 4 and adjusting screw rod 11.It is arranged with and is used for adjusting screw rod on adjusting screw rod 11
11 are fixed on the clamp ring 13 on bonnet 10, and cap body 12 is arranged with adjusting screw rod 11, and cap body 12 connects with the screw thread of bonnet 10
Connect.
When antivoid valve is installed, its access way is connected in the pipe-line system of working equipment, in antivoid valve,
Valve rod 6 is withstood on to the back on valve top 3 by spring 5, and then valve top 3 is contacted with valve body 1, access way is closed；Work as pipeline
When pressure in system is excessive, then the elastic force of spring 5 can be overcome, then open the top of valve top 3, so as to which fluid media (medium) be incorporated into
In valve body 1, drain from the porus excretorius on valve body 1, realize pressure release, protect the working equipment in pipe-line system, avoid operating pressure
It is excessive and to working equipment formed destroy.
Seal face of the utility model on the valve top 3 being in contact with valve body 1 is provided with dovetail annular groove 14, dovetail annular groove 14
In be provided with sealing ring 2, sealing ring 2 is preferably O-ring seals.Sealing between valve top 3 and valve body 1 is realized by sealing ring 2
Connection, by being arranged to the dovetail annular groove 14 of swallowtail-shaped structure, the structure can effectively prevent sealing ring 2 from coming off, and press
When power is higher, sealing effectiveness is more preferable.
