Description
Technical field
The present invention relates to the accessory technical fields of gas-cooker, more particularly, to a kind of plug valve.
Background technique
Embedded gas range, which refers to, is made into concave for cabinet table surface, just embeddable gas-cooker, the stove cabinet of gas-cooker
With cabinet table surface at a plane.Since embedded gas range is beautiful, saves space, easy cleaning, make kitchen seem more with it is harmonious
Completely, it has been more convenient the Aided design provided with other, therefore, has had received liking for the majority of consumers, Hen Suo family is fitting up
Such gas cooker is all selected when new house, plug valve is an important accessory of embedded gas range, in the prior art,
As shown in Fig. 3, the stopcock structure of gas-cooker by valve body 1A, the spool 2A being installed in valve body 1A, pass through fabrication hole and spool
Time fire venthole 3A of 2A connection is constituted, and in the structure, secondary fire venthole 3A is vertical with the central axes of spool 2A, and fabrication hole includes
The first fabrication hole 4A for being connected to secondary fire venthole 3A, the second fabrication hole 5A being connected to the first fabrication hole 4A and spool 2A and
Third the fabrication hole 6A, the first fabrication hole 4A being connected to spool 2A are vertical with time fire venthole 3A, the second fabrication hole 5A and time fire
Venthole 3A is parallel, and third fabrication hole 6A is parallel with time fire venthole 3A, passes through the first steel ball in the end of the first fabrication hole 4A
7A is sealed, and is sealed in the end of the second fabrication hole 5A by the second steel ball 8A, in the end of third fabrication hole 6A
It is sealed by third steel ball 9A, is the principle of this kind of plug valve are as follows: gas source in order to reduce combustion gas and leak by steel ball sealing
It is entered in the second fabrication hole 5A by spool, the first fabrication hole 4A is entered by the second fabrication hole 5A, then by the first fabrication hole
4A enters time fiery venthole 3A, meanwhile, gas source enters third fabrication hole 6A also by spool 2A, passes through flow regulating nail
10A adjusting enters gas source in time fiery venthole 3A by third fabrication hole 6A.There are own shortcomings for the structure of this kind of plug valve:
1, by steel ball come sealing technology hole, still there can be the case where combustion gas leaks, can not avoid completely；2, technique requires high, needs
Multistage technology hole is opened up, and to be also embedded in steel ball, reduces production efficiency；3, consumptive material is more, and cost improves.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind can be avoided combustion gas leak, reduce technique require, improve
Production efficiency, and the plug valve of reduced cost.
The technical scheme adopted by the invention is that a kind of plug valve, including cock valve body, cock valve body include valve
Body, positioned at venthole valve intracorporal spool and connect with valve body, venthole includes venthole ontology and air vent wall, cock
Valve body further includes the main fabrication hole through air vent wall, and main fabrication hole one end is connected to spool, and the other end is connected to stomata ontology,
Main fabrication hole is set as incline structure.
The beneficial effects of the present invention are: plug valve using the above structure, is arranged one between spool and venthole ontology
The main fabrication hole of a incline structure, is connected to spool with venthole ontology, and gas source enters main fabrication hole by spool, then from main work
Skill hole enters venthole ontology, and the main fabrication hole of above structure, which is not present, is exposed to extraneous port, without passing through other portions
Part (such as: steel ball) is sealed, and can play the role of the case where being fully sealed, combustion gas capable of being avoided to leak completely hair
It is raw, and it also is connected to venthole ontology and spool not necessarily like two fabrication holes are arranged in original technology, technique requirement is reduced,
The production efficiency of plug valve is improved, this kind of structure saves the use of components, consumptive material is reduced, to reduce cost.
As preferential, cock valve body further includes that the flow regulating nail being embedded in air vent wall and one end and flow are adjusted
The secondary fabrication hole that the nail connection other end is connected to spool, venthole ontology includes the interconnecting part being connected to flow regulating nail, is used
The structure, gas source enter secondary fabrication hole by spool, then pass through flow regulating nail and enter in venthole from interconnecting part, stream
Amount regulating nail can be used to adjust the gas flow entered by secondary fabrication hole in venthole, and in the structure, secondary fabrication hole is not present
There is the place of communication with the external world, without being sealed by other component (such as: steel ball), the work being fully sealed can be played
With；And the gas in secondary fabrication hole directly passes through flow regulating nail and enters in venthole, regulating gas it is high-efficient.
As preferential, flow regulating nail and secondary fabrication hole are disposed as incline structure, and flow regulating nail and secondary fabrication hole
On same central axes, using the structure, flow regulating nail and secondary fabrication hole tilt and are located on same central axes, in this way
It just can guarantee that spool is connected to venthole ontology, so that secondary fabrication hole is not exposed to extraneous port, eliminate making for steel ball
With, and the volume of cock valve body can be reduced, reduce space size.
As preferential, the range of tilt angles of main fabrication hole is 30 °~75 °, and using the structure, which can
To guarantee that spool is connected to venthole, can play the case where being fully sealed, combustion gas is avoided to leak.
As preferential, the tilt angle of main fabrication hole is 40 °, and using the structure, which can guarantee valve
Core is connected to venthole, can be played the case where being fully sealed, combustion gas is avoided to leak.
As preferential, the range of tilt angles of flow regulating nail and secondary fabrication hole is 40 °~80 °, and using the structure, this inclines
Rake angle range can guarantee that spool is connected to venthole, can play the case where being fully sealed, combustion gas is avoided to leak.
As preferential, the range of tilt angles of flow regulating nail and secondary fabrication hole is 50 °, using the structure, the inclination angle
Degree range can guarantee that spool is connected to venthole, can play the case where being fully sealed, combustion gas is avoided to leak.
As preferential, main fabrication hole is located at the side of venthole ontology bottom end, and secondary fabrication hole is located at venthole ontology bottom end
The other side, using the structure, gas source passes through main fabrication hole respectively and secondary fabrication hole enters in venthole ontology, gas source flow direction
Path it is short, gas flow efficiency is high, improves sparking efficiency.
As preferential, main fabrication hole is an integral molding structure with venthole ontology, using the structure, it is ensured that main technique
Gas in hole unimpededly enters in venthole ontology, and without gap at any connection, can avoid gas completely
The phenomenon that leaking.
