Abstract
A kind of spring clamping valve, including valve body, switch lever, it is arranged on the spool of switch lever end, air intake installation, safety device and decompressor, described switch lever includes shank, polished rod portion, threaded portion and is arranged on the spool mounting seat of end, there is a counterbore on described switch lever passage, switch lever passage has female thread；Also including that the axial end portion that a compression spring, described compression spring one end are enclosed within spool mounting seat with threaded portion coordinates, another coordinates with the dividing plate at valve core case, threaded portion and switch lever passage liquid hermetic seal, polished rod portion and counterbore liquid hermetic seal.Owing to using such structure, owing to compression spring acts on the dividing plate at switch lever and valve core case, during rotary switch bar, the tension overcoming frictional force and compression spring between compression spring and threaded portion axial end portion is needed to rotate；Overcome in prior art, during use, due to the knob of careless touch switch boom end, and make switch lever rotate, cause the defect of flame instability.
Description
Technical field
The present invention relates to a kind of cassette cooker gas valve.
Background technology
Currently available technology, Chinese patent ZL201320062584.6, denomination of invention: spring clamping valve.Including valve body, switch lever, it is arranged on the spool of switch lever end, air intake installation, safety device and decompressor, described valve body includes inlet chamber, secure chamber, relief chamber and the switch lever passage communicated with relief chamber, being provided with valve core case on dividing plate between switch lever passage and relief chamber, spool coordinates with valve core case；Switch lever is rotatably assorted with switch lever passage.Existing problems are: being arranged on the knob of switch lever end, easily acted on by external force, switch lever rotates, and cause burner flame unstable.
Summary of the invention
It is an object of the invention to: provide a kind of spring clamping valve, it can effectively prevent the impact of external force, make switch lever rotate, and keeps burner flame stable.
The present invention is achieved in that a kind of spring clamping valve, including valve body, switch lever, it is arranged on the spool of switch lever end, air intake installation, safety device and decompressor, described valve body includes inlet chamber, secure chamber, relief chamber and the switch lever passage communicated with relief chamber, being provided with valve core case on dividing plate between switch lever passage and relief chamber, spool coordinates with valve core case；
It is characterized in that described switch lever includes shank, polished rod portion, threaded portion and is arranged on the spool mounting seat of end,
There is a counterbore on described switch lever passage, switch lever passage has female thread；
Also including that the axial end portion that a compression spring, described compression spring one end are enclosed within spool mounting seat with threaded portion coordinates, another coordinates with the dividing plate at valve core case, threaded portion and switch lever passage liquid hermetic seal, polished rod portion and counterbore liquid hermetic seal.
Described a kind of spring clamping valve, it is characterized in that the end of one end of elastic metallic yarn of described compression spring or the end at two ends are bent into smooth arc.
Described a kind of spring clamping valve, it is characterized in that the polished rod portion of described switch lever is provided with annular groove, also includes that sealing ring, sealing ring are arranged in annular groove.
A kind of spring clamping valve, it is characterized in that the axial end portion of described spool mounting seat has a blind hole, in described spool embedding blind hole；Described valve core case is cylindrical in shape, and valve core case coordinates with spool.
One spring clamping valve of the present invention, owing to using such structure, owing to compression spring acts on the dividing plate at switch lever and valve core case, during rotary switch bar, needs the tension overcoming frictional force and compression spring between compression spring and threaded portion axial end portion to rotate；Overcome in prior art, during use, due to the knob of careless touch switch boom end, and make switch lever rotate, cause the defect of flame instability.
Accompanying drawing explanation
Fig. 1 is the axonometric chart of the present invention.
Fig. 2 is the sectional view of the present invention.
Fig. 3 is the partial enlarged drawing of Fig. 2.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, a kind of spring clamping valve, including valve body 1, switch lever 2, it is arranged on the spool 3 of switch lever 2 end, air intake installation 4, safety device and decompressor 5, described valve body 1 includes that the inlet chamber 11 of air intake installation 4, secure chamber, the relief chamber 12 of decompressor 5 and the switch lever passage 13 communicated with relief chamber, switch lever passage 13 are connected by a gas port 14 with relief chamber 12；Being provided with valve core case 6 on dividing plate between switch lever passage 13 and relief chamber 12, valve core case 6 is positioned on the dividing plate of switch lever passage 13, the through valve core case of gas port 6；Spool 3 coordinates with valve core case 6；Being arranged on escape pipe 7 on switch lever passage 13, escape pipe 7 coordinates with burner.
Described switch lever 2 includes shank 21, polished rod portion 22, threaded portion 23 and is arranged on the spool mounting seat 24 of end,
As it is shown on figure 3, there is a counterbore 131 on described switch lever passage 13, switch lever passage 13 there is female thread；
Also include a compression spring 8, the axial end portion that described compression spring 8 one end is enclosed within spool mounting seat 24 with threaded portion 23 coordinates, another coordinates with the dividing plate at valve core case 6, threaded portion 23 and switch lever passage 13 threaded engagement liquid hermetic seal, polished rod portion 22 and counterbore 131 slide and are slidably matched and liquid hermetic seal.
Rotary switch bar 2, threaded portion 23 is subjected to displacement relative to switch lever passage 13, and polished rod portion 22 rotates with counterbore 131 and is slidably matched；Thus realize spool 3 and fit with valve core case 6 or separate.
The end of one end or the end at two ends of the elastic metallic yarn of described compression spring 8 are bent into smooth arc.
As it is shown on figure 3, the polished rod portion 22 of described switch lever 2 is provided with annular groove, also include that sealing ring 9, sealing ring 9 are arranged in annular groove.
The axial end portion of described spool mounting seat 24 has a blind hole, described spool 3 to embed in blind hole；
Described valve core case 6 is cylindrical in shape, and valve core case coordinates with spool.
Above-described is only the preferred embodiments of the present invention.It should be pointed out that, for the person of ordinary skill of the art, without departing from the principles of the present invention, it is also possible to make some improvement and modification, this is also considered as protection scope of the present invention.
