Description
Technical field
The utility model belongs to valve technology field, more particularly, to a kind of butterfly valve body with novel fixation hole.
Background technique
Butterfly valve is called flap valve, is a kind of simple regulating valve of structure, currently, the valve body installation valve seat and valve of existing butterfly valve
It is positioned by fixation hole when bar, the mounting hole of valve seat is usually directed at positioning with the fixation hole of valve body, valve rod is passed through into peace
It fills hole and fixation hole is installed, but poor sealing between the axially position and valve seat and valve body of this structure, valve body, valve seat
Gap is easy to produce with the position of valve rod three joint.
Summary of the invention
Problem to be solved in the utility model is to provide that a kind of structure is simple, and sealing effect is good, the convenient and fast band of installation and replacement
There is the butterfly valve body of novel fixation hole.
In order to solve the above technical problems, the technical solution adopted in the utility model is: a kind of butterfly with novel fixation hole
Valve body, including valve body ontology, the corresponding position of the valve body ontology upper and lower ends are equipped with fixation hole, and the fixation hole leans on
Nearly valve body body internal surface position is provided with annular seal groove, and the annular seal groove diameter is greater than fixed hole diameter, the annular
Seal groove and fixation hole are coaxially disposed.
The ring packing groove sidewall is provided with circular orientation groove.
The annular seal groove bottom position is frosted structure.
Sealing ring is provided in the annular seal groove.
The valve body ontology is split type structure, connects fixation by screw.
Due to the adoption of the above technical scheme, the utility model overall structure is simple, and valve body ontology upper and lower ends are corresponding
Position is equipped with fixation hole, and the fixation hole is provided with annular seal groove close to valve body body internal surface position, the ring packing
It is provided with sealing ring in slot, seal groove and sealing ring are increased in fixation hole, has made between valve body, valve rod and valve seat sealing more
Structure, more matches, good airproof performance between fixation hole and valve seat valve rod, and axially position is good；Ring packing groove sidewall is provided with ring
Shape positioning groove, annular seal groove bottom position are frosted structure, and positioning sealing ring and annular seal groove more acurrate more has guarantor
Barrier, strengthens sealing effect；Valve body ontology is that split type structure keeps the installation and replacement of valve seat, valve rod, sealing ring more convenient.
The beneficial effects of the utility model are: having structure simple, sealing effect is good, the convenient advantage of installation and replacement.
Detailed description of the invention
The utility model is specifically described below with reference to attached drawing and in conjunction with example, the advantages of the utility model and realization
Mode will be more obvious, and wherein content shown in attached drawing is only used for the explanation to the utility model, without constituting to this reality
With it is novel in all senses on limitation, in the accompanying drawings:
Fig. 1 is the utility model structure diagram
In figure:
1, valve body ontology 2, fixation hole 3, annular seal groove
4, circular orientation groove
Specific embodiment
As shown in Figure 1, a kind of butterfly valve body with novel fixation hole of the utility model, including valve body ontology 1, the valve
The corresponding position of 1 upper and lower ends of body ontology is equipped with fixation hole 2, and the fixation hole 2 is set close to 1 inner surface position of valve body ontology
It is equipped with annular seal groove 3,3 diameter of annular seal groove is greater than 2 diameter of fixation hole, and the annular seal groove 3 and fixation hole 2 are coaxial
Setting；3 side wall of annular seal groove is provided with circular orientation groove 4；3 bottom position of annular seal groove is frosted knot
Structure；Sealing ring is provided in the annular seal groove 3；The valve body ontology 1 is split type structure, is connected by screw solid
It is fixed.
The utility model overall structure is simple, and the corresponding position of 1 upper and lower ends of valve body ontology is equipped with fixation hole 2, institute
It states fixation hole 2 and 1 inner surface position of valve body ontology is provided with annular seal groove 3, be provided with sealing in the annular seal groove 3
Circle, increases seal groove and sealing ring in fixation hole 2, has made between valve body, valve rod and valve seat sealing structure more, fixation hole 2
It is more matched between valve seat valve rod, good airproof performance, axially position is good；3 side wall of annular seal groove is provided with circular orientation groove
4,3 bottom position of annular seal groove is frosted structure, positions sealing ring with annular seal groove 3 more acurrate more secure, is reinforced
Sealing effect；Valve body ontology 1 is that split type structure keeps the installation and replacement of valve seat, valve rod, sealing ring more convenient.
The embodiments of the present invention are described in detail above, but the content is only the preferable of the utility model
Embodiment should not be considered as limiting the scope of the present invention.It is all to become according to equalization made by the scope of the utility model
Change and improve etc., it shall still fall within the scope of this patent.
