Description

Technical Field

[0001] This utility model relates to the field of pressure cooker valve technology, and in particular to a check valve with pressure indication. Background Technology

[0002] Existing pressure cookers are typically equipped with a pressure valve and a check valve. The pressure valve is located on the surface of the lid and is used to increase or decrease the pressure inside the pot. The check valve is located inside the handle and has a push rod and a valve cap. When there is no pressure inside the pot, the push rod and valve cap retract into the handle, and the user can open the pressure cooker lid through the handle. When there is pressure inside the pot, the push rod extends, and the user cannot open the pressure cooker lid through the handle.

[0003] The shortcomings of existing check valves: When there is pressure inside the pot, the push rod and valve cap of existing check valves extend under the pressure of the gas inside the pot, but the valve cap remains inside the pot handle. Users cannot clearly observe the status of the check valve. Possible situations that may occur when the check valve is inside the pot handle:

[0004] Firstly, if the pressure cooker leaks and the pressure is insufficient, the check valve cannot extend, preventing the user from cooking the food inside.

[0005] Secondly, the check valve was stuck by other parts inside the pot handle and could not be extended. The user continued to heat the pressure cooker without knowing it, causing the pressure inside the pot to exceed the safe pressure. The user could not observe or judge this unsafe state and failed to take timely measures, resulting in an accident. Utility Model Content

[0006] To address the above-mentioned problems, the technical problem to be solved by this utility model is to provide a check valve with pressure indication.

[0007] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a check valve with pressure indication, comprising a valve body and a mounting seat that slides vertically with the valve body, wherein the valve body and the mounting seat are disposed inside the pot handle, characterized in that the mounting seat is provided with a vertically sliding indicator valve rod, the top of the indicator valve rod is provided with an indicator bar that displays the pressure inside the pot, the bottom of the indicator valve rod is provided with a sealing sleeve, the mounting seat abuts against the pot handle under the action of the pressure inside the pot, and after the mounting seat abuts against the pot handle, the pressure inside the pot continues to squeeze the sealing sleeve, causing the indicator valve rod to continue to extend upward.

[0008] A further preferred embodiment of this utility model is that the valve body is provided with a through hole for the mounting seat to slide up and down.

[0009] A further preferred embodiment of this utility model is: an inwardly extending boss is provided in the through hole, and a fixed seat is provided on the mounting base; when there is no pressure inside the pot, the fixed seat and the boss abut against each other.

[0010] The further preferred scheme of the utility model is that a reset spring for resetting the indicating valve rod is arranged between the fixed seat and the indicating valve rod.

[0011] The further preferred scheme of the utility model is that an abutting surface is arranged on the indicating valve rod, one end of the reset spring is arranged on the fixed seat, and the other end is abutted on the abutting surface.

[0012] The further preferred scheme of the utility model is that a convex rib extending outward is arranged on the mounting seat, and the sealing sleeve is sleeved on the convex rib and wraps the bottom end of the indicating valve rod.

[0013] The further preferred scheme of the utility model is that a connecting seat for fixing the valve body on the pot handle is arranged on the valve body.

[0014] The further preferred scheme of the utility model is that the indicating strip is divided into a first indicating strip and a second indicating strip, when the first indicating strip is displayed outside, the pressure in the pot body is small.

[0015] The further preferred scheme of the utility model is that when the first indicating strip and the second indicating strip are displayed outside at the same time, the pressure in the pot body is large.

[0028] It should be noted that similar reference numerals refer to similar items in the following drawings, so once an item is defined in one drawing, it may not be further defined and explained in subsequent drawings.

[0029] The present embodiment mainly describes a stop valve with pressure indication, which is specifically as follows:

[0030] As shown in Figure 1 , Figure 2 , a stop valve with pressure indication comprises a pot handle 14, a valve body 5 and a mounting seat 8, wherein the valve body 5 and the mounting seat 8 are arranged in the pot handle 14, and the mounting seat 8 is arranged in the valve body 5. Specifically, the valve body 5 is provided with a through hole 7, and the mounting seat 8 passes through the through hole 7 and is in sliding fit with the valve body 5.

[0031] The top end of the mounting seat 8 is provided with a fixed seat 10, and the fixed seat 10 is fixedly connected with the mounting seat 8 through threads, so that the fixed seat 10 synchronously slides with the mounting seat 8 in the through hole 7.

[0032] As shown in Figure 5 , the through hole 7 is provided with a protrusion 13 extending inwardly, when the pressure cooker is normally placed, there is no pressure in the pot body, the fixed seat 10 and the protrusion 13 abut each other to prevent the mounting seat 8 from sliding out of the through hole 7 in the valve body 5.

[0033] As shown in Figure 4 , the mounting seat 8 is provided with an indicating valve stem 3 and a return spring 11, the indicating valve stem 3 passes through the fixed seat 10 and slides up and down in the mounting seat 8.

[0034] As shown in Figure 5 , the fixed seat 10 and the indicating valve stem 3 are provided with a return spring 11, specifically, one end of the return spring 11 is fixedly connected with the bottom of the fixed seat 10, the indicating valve stem 3 is provided with an abutting surface 12, the other end of the return spring 11 abuts against the abutting surface 12, when the pressure cooker is normally placed, there is no pressure in the pot body, the return spring 11 is in a natural stretched state, keeping the indicating valve stem 3 in the initial position.

[0035] As shown in Figure 3 , the lower end of the indicating valve stem 3 is provided with a sealing sleeve 6 on the part extending out of the valve body 5, the sealing sleeve 6 is made of high-temperature-resistant rubber material.

[0036] In order to more stably install the sealing sleeve 6, the mounting seat 8 is provided with an outwardly extending protrusion 9, the sealing sleeve 6 is sleeved on the protrusion 9, and the lower end of the indicating valve stem 3 is wrapped in the sealing sleeve 6, which better fixes the position of the sealing sleeve 6 and prevents it from moving during work.

[0037] The upper end of the indicating valve stem 3 extends out of the valve body 5 from the fixed seat 10, and is provided with an indicating strip showing the pressure in the pot body, specifically, the indicating strip has two, from top to bottom, the first indicating strip 1 and the second indicating strip 2, as the pressure in the pot changes, the position of the indicating valve stem 3 sliding up and down in the mounting seat 8 changes, the first indicating strip 1 or the first indicating strip 1 and the second indicating strip 2 appear in the user's field of vision at the same time, the user can intuitively judge the pressure in the pot through the indicating strip.

[0038] According to the different indicating strips extending out of the upper end of the indicating valve stem 3, the pressure cooker can be divided into different states:

[0039] As shown in Figure 5 , the first state, when the pressure cooker is in idle state, i.e. there is no pressure in the pot body, the fixed seat 10 in the mounting seat 8 and the protrusion 13 in the through hole 7 of the valve body 5 abut each other, the indicating valve stem 3 is in the initial position under the action of the return spring 11, the first indicating strip 1 and the second indicating strip 2 are both in the pot handle 14, and the user cannot see the first indicating strip 1 and the second indicating strip 2 in the field of vision.

[0040] As Figure 6 shown, the second state, when the pressure cooker starts cooking food, the pot body starts to heat up and increase pressure, the pressure in the pot acts on the mounting seat 8 and the sealing sleeve 6 sleeved on the mounting seat 8, so that the mounting seat 8 slides upward along the through hole 7, at the same time, the fixing seat 10 rises synchronously with the mounting seat 8, and is separated from the boss 13 in the through hole 7, and rises to abut against the bottom of the pot handle 14, and the rising action of the mounting seat 8 stops after abutting, at this time, the first indicating bar 1 on the indicating valve rod 3 can be seen in the user's field of view.

[0041] As Figure 7 shown, the third state, in the case of the second state, the pressure in the pot continues to increase, the sealing sleeve 6 made of rubber is extruded by the pressure in the pot and is transmitted to the indicating valve rod 3 wrapped by the sealing sleeve 6, and continues to push the indicating valve rod 3 to extend upward, at this time, the first indicating bar 1 and the second indicating bar 2 can be seen in the user's field of view, and the pressure reduction measure can be taken to prevent accidents caused by excessive pressure in the pot.

[0042] When the pressure in the pot gradually decreases, the indicating valve rod 3 moves downward under the action of the reset spring 11 and the mounting seat 8, until the fixing seat 10 and the boss 13 in the through hole 7 abut against each other again, and returns to the initial state.

[0043] The valve body 5 is provided with a connecting seat 4 for fixing the valve body 5 on the pot handle 14, and the connecting seat 4 can be connected with the pot handle 14 in various ways, such as welding, threaded connection or clamping, etc., to ensure that the valve body 5 is stably connected with the pot handle and can withstand the pressure in the pot and work normally.
