The utility model content
The purpose of this utility model is to provide a kind of and can stirs the anglec of rotation to pressure limiting valve and carry out spacing limiting valve of pressure cooker.
The utility model comprises following technical characterictic: a kind of limiting valve of pressure cooker comprises valve body, handle and pressure limiting valve seat; Valve body is arranged in the handle cavity, the handle cover inserts in the pressure limiting valve seat, the lower end that handle inserts the pressure limiting valve seat part has high breach and low breach, be provided with the projection that matches with high breach and low breach in the pressure limiting valve seat, described handle lateral surface is provided with the pressure limiting valve locating convex block, described pressure limiting valve base inner surface is provided with the pressure limiting valve locating convex block and carries out spacing stopper slot, described pressure limiting valve rotates in the spacing mutually angular range of pressure limiting valve locating convex block and stopper slot, and the high breach of described handle and low breach match with projection in the pressure limiting valve seat in this angular range.
The utility model cooperates spacing by pressure limiting valve locating convex block and stopper slot, make pressure limiting valve to rotate within limits, has overcome the problem that the anglec of rotation can not be located in the prior art.
Described pressure limiting valve locating convex block and stopper slot spacing angular range mutually are 60～90 degree.
Rotation angle range in the utility model can be by the pressure limiting valve locating convex block be set size and the size of stopper slot be provided with.
Therefore further, described pressure limiting valve locating convex block is a reference column with certain width; Perhaps be two spacers that have the identical of certain distance and be arranged in parallel.If a reference column, as long as adjust the width of this reference column; If two spacers, need only the distance of adjusting between the spacer, just can adjust the size of whole pressure limiting valve locating convex block.
In addition, further, described stopper slot is 120～180 degree along the angle of pressure limiting valve seat circumference setting.
Further, be provided with step along the valve seat circumference in the described pressure limiting valve seat, described stopper slot is the breach that is provided with on the step; The length of described locating convex block is suitable with the degree of depth of breach.Described handle top sides is along being provided with flange, and the interior step of described flange and pressure limiting valve seat matches.Described flange is connected with the pressure limiting valve locating convex block.
The utility model compared with prior art, has following beneficial effect: because handle is provided with the pressure limiting valve locating convex block, on the pressure limiting valve seat, stopper slot is set, setting by pressure limiting valve locating convex block and stopper slot, the anglec of rotation to pressure limiting valve is carried out spacing, make pressure limiting valve to rotate within limits, overcome the problem that the pressure limiting valve anglec of rotation can not be located in the prior art.The user in use seals the switching with exhaust in this anglec of rotation, avoided the potential safety hazard of manual operation.

The specific embodiment
As Fig. 1, Fig. 2, Fig. 5, shown in Figure 6, the structural representation for the pressure limiting valve sleeve on pressure limiting valve seat 3 time.Pressure limiting valve has constant weight, comprises valve body 2, handle 1 and pressure limiting valve seat 3; Valve body 2 is made for the metal material with constant weight, is fixed with thimble in the valve body 2, and thimble matches with blast pipe 8 on the pressure limiting valve seat 3; Establish cavity in the handle 1, valve body 2 closely is fixed in handle 1 cavity; Handle 1 cover inserts in pressure limiting valve seat 3, and the lower end that handle 1 inserts pressure limiting valve seat 3 parts has high breach 11 and low breach 12, is provided with the projection 4 that matches with high breach 11 and low breach 12 in the pressure limiting valve seat 3.High breach 11 and low breach 12 4 match with projection, realize the upper and lower displacement of pressure limiting valve: when be high breach 11 on the projection 4, pressure limiting valve is downwards whole, and thimble withstands the blast pipe 8 on the pressure limiting valve seat 3, is sealing state at this moment; When being that pressure limiting valve is upwards whole when hanging down breach 12 on the projection 4, thimble leaves blast pipe 8, and be exhaust condition this moment.
Innovation of the present utility model is to cooperate by pressure limiting valve locating convex block 7 and stopper slot 5 spacing, makes pressure limiting valve to rotate within limits, has overcome the problem that the anglec of rotation can not be located in the prior art.Be specially as shown in Figure 3, Figure 4: described handle 1 lateral surface is provided with pressure limiting valve locating convex block 7, described pressure limiting valve seat 3 inner surfaces are provided with pressure limiting valve locating convex block 7 and carry out spacing stopper slot 5, described pressure limiting valve rotates in the spacing mutually angular range of pressure limiting valve locating convex block 7 and stopper slot 5, and the high breach 11 of described handle 1 and low breach 12 match with projection 4 in the pressure limiting valve seat 3 in this angular range.
After process pressure limiting valve locating convex block 7 and stopper slot 5 cooperations were spacing, pressure limiting valve can only rotate within limits, was 60～90 degree as this angular range, was preferably 60 degree.
Rotation angle range in the utility model can be by pressure limiting valve locating convex block 7 be set size and the size of stopper slot 5 be provided with.
In general, pressure limiting valve locating convex block 7 can be a reference column with certain width; But in order to save material, pressure limiting valve locating convex block 7 also can be two spacers that have the identical of certain distance and be arranged in parallel.If a reference column, as long as adjust the width of this reference column; If two spacers, need only the distance of adjusting between the spacer, just can adjust the size of whole pressure limiting valve locating convex block 7.
In addition, further, described stopper slot is 120～180 degree along the angle of pressure limiting valve seat circumference setting.
Further, be provided with step 6 along the valve seat circumference in the described pressure limiting valve seat 3, described stopper slot 5 is the breach that is provided with on the step 6; The length of described pressure limiting valve locating convex block 7 is suitable with the degree of depth of breach.Described handle top sides is along being provided with flange 13, and the interior step 6 of described flange 13 and pressure limiting valve seat matches.Described flange 13 is connected with pressure limiting valve locating convex block 7.
