Background technology
There are a valve element and a valve seat in single-seat adjusting valve valve body, there is the characteristics of leakage rate is small.The valve out-of-balance force
Greatly, its permissible pressure is small compared with double-beat drop valve, in High Pressure Difference, heavy caliber, preferably mixes valve positioner.Inside nominal diameter >=25mm's
Valve is dual-guiding structure, as long as the link position of change valve rod and valve element achieves that the on or off of liquid medium.And show
The connecting mode of structured single-seat adjusting valve uses traditional bolt fastener mostly, and installation is set on bonnet and valve body
Hole, then it is fixed by bolt, is had as a drawback that using which：
1st, due to needing to open up mounting hole on bonnet and valve body respectively, this integral rigidity structure meeting to valve body and bonnet
Impact, easily cause the infringement of bonnet；In addition, during installation and removal, if operation and improper use, can also make
Into bolt fracture in mounting hole, it is difficult to remove, now may need to change bonnet, or even also need to change valve body so that
Maintenance of equipment and replacing are extremely inconvenient, and maintenance replacing construction is elongated, that is, influence to use and very dangerous, cause tremendous economic to damage
Lose.
2nd, due to being fixedly connected between bonnet and valve body using bolt, it is impossible to which satisfaction is prevented outside precious material and hypertoxic medium
The requirement let out, the sealing between bonnet and valve body is caused to be deteriorated, liquid easily leaks from gap between the two, holds
The injury to the person is easily caused, or serious economic loss is caused to client.
3rd, due to being directly fixedly connected using bolt between bonnet and valve body.When mounted, can not be by bonnet and valve
Mounting hole between body is fast and accurately positioned, the needs frequent adjustment position between mounting hole up and down when causing the bolt to fix
Put so that handling are very slow.
Utility model content
The purpose of the utility model is that a kind of single-seat adjusting valve is provided the defects of presence for prior art.
The utility model to achieve the above object, adopts the following technical scheme that：A kind of single-seat adjusting valve, including valve body, institute
State and bonnet is provided with valve body, the lower end of the bonnet is engaged part with the valve body and is provided with circular bonnet flange, described
The upper end of valve body is engaged part with the bonnet and is provided with circular valve flange, and the outward flange of the circular bonnet flange is downward
Type inclined-plane is carved provided with first, type inclined-plane is carved in the outward flange of the circular valve flange provided with second upwards；Described first to carve type oblique
Face carves to be formed after type inclined-plane coordinates with described second two-sided carves type inclined-plane outside flanged ring；It is two-sided outside the flanged ring to carve outside type inclined-plane
Portion is covered with two semicircle anchor ears, the semicircle anchor ear boring and provided with carving type inclined-plane with two-sided outside the flanged ring
It is two-sided in the anchor ear being engaged to carve type inclined-plane；Part connection is fastened by bolts between the semicircle anchor ear.
Further, it is provided with sealing ring between the circular bonnet flange and the circular valve flange.
Further, the lower surface of the circular bonnet flange is vertically provided with alignment pin, the circular valve flange
Upper surface is provided with the Blind locating holes corresponding with the alignment pin.
Further, the bottom of the alignment pin has set up a buffering blind hole, and one is provided with the buffering blind hole
The buffer spring that can be connected in the Blind locating holes.
The beneficial effects of the utility model：It is convenient to be mounted and dismounted between bonnet and valve body of the present utility model, installs
In journey mechanical damage will not be produced to valve body and bonnet.And above-mentioned mounting structure is used, enable between valve body and bonnet
Sealing is better, prevents from revealing.
Brief description of the drawings
Fig. 1 main view schematic diagrams of the present utility model.
A is to partial enlargement structural representation in Fig. 2 the utility model Fig. 1.
Fig. 3 vertical view figure structure schematic representations of the present utility model.
Embodiment
Fig. 1 to Fig. 3 is illustrated, and is related to a kind of single-seat adjusting valve, including valve body 2, bonnet 1 is provided with the valve body 2, described
The lower end of bonnet 1 is engaged part with the valve body 2 and is provided with circular bonnet flange 13, upper end and the valve of the valve body 2
Lid 1 is engaged part and is provided with circular valve flange 21, and type is carved in the outward flange of the circular bonnet flange 13 to having first
Type inclined-plane 22 is carved in inclined-plane 14, the outward flange of the circular valve flange 21 provided with second upwards；Described first carve type inclined-plane 14 with
Described second carves to be formed after type inclined-plane 22 coordinates outside flanged ring and two-sided carves type inclined-plane；It is two-sided outside the flanged ring to carve outside type inclined-plane
Be covered with two semicircle anchor ears 31, the boring of semicircle anchor ear 31 and provided with two-sided outside the flanged ring to carve type oblique
It is two-sided in the anchor ear that face is engaged to carve type inclined-plane；Part 32 is fastened by bolts between the semicircle anchor ear 31 to connect.
In such scheme, in order that obtaining has better seal performance between bonnet and valve body, it is convex in the circular bonnet
Sealing ring 33 is provided between edge 13 and the circular valve flange 21.
When bolt fastener 32 is fastened, the interior two-sided type inclined-plane of carving of two semicircle anchor ears 31 is to double outside flanged ring
Face Qie Xing inclined-planes produce thrust, while by two adjacent valve bodies and bonnet flange fastening, will also be set between two flanges
Seal 33 compress, not only realized the quick connection between bonnet and valve body but also realized fast sealing, will not be right in installation process
Valve body and bonnet produce mechanical damage, are applicable high-temperature severe environment.
