Embodiment Construction

[0015] The present invention will be further described below in conjunction with the drawings.

[0016] Such as figure 1 , figure 2 As shown, an improved spring-loaded cassette valve includes a valve body 1, a switch lever 2, a valve core 3 arranged at the end of the switch lever 2, an air intake device 4, a safety device and a pressure reducing device 5. The valve The body 1 includes the air inlet cavity 11 of the air inlet device 4, the safety cavity, the decompression cavity 12 of the decompression device 5, and the switch lever passage 13 communicating with the decompression cavity. The switch lever passage 13 and the decompression cavity 12 pass through an air guide hole 14 is connected; a valve core seat 6 is provided on the partition between the switch rod passage 13 and the pressure relief chamber 12, the valve core seat 6 is located on the partition in the switch passage 13, and the air guide hole penetrates the valve core seat 6; the valve core 3 It is matched with the...

Abstract

An improved spring type cassette valve comprises a valve body, a switch lever, a valve core arranged at the end of the switch lever, an air inlet device, a safety device and a pressure reducing device, wherein the switch lever comprises the handle portion, the polish rod portion, the thread portion and a valve core installing seat arranged at the end, and a switch channel is provided with a counter bored hole and inner threads. The improved spring type cassette valve further comprises a pressure spring, wherein the valve core installing seat is sleeved by one end of the pressure spring, the end of the pressure spring is matched with the axial end of the thread portion, the other end of the pressure spring is matched with a partition plate at the position of the valve core seat, the thread portion and the switch channel are subjected to liquid-gas sealing, and the polish rod portion and the counter bored hole are subjected to liquid-gas sealing. By adopting the structure, due to the fact that the pressure spring acts on the partition plate at the positions of the switch lever and the valve core seat, friction force between the pressure spring and the axial end of the thread portion and tension rotation of the pressure spring are overcome when the switch lever is turned. The defect that a rotary knob at the end of the switch lever is accidentally touched to enable the switch lever to rotate and accordingly flame is unstable when the improved spring type cassette valve is used in the prior art is overcome.

Description

Technical field [0001] The invention relates to a gas valve for a cassette furnace. Background technique [0002] The current existing technology, Chinese patent ZL201320062584.6, invention name: spring-type cassette valve. It includes a valve body, a switch lever, a valve core arranged at the end of the switch lever, an air intake device, a safety device, and a pressure reducing device. The valve body includes an air inlet cavity, a safety cavity, a decompression cavity, and a pressure relief cavity. A valve core seat is arranged on the switch rod channel, the partition between the switch rod channel and the decompression chamber, and the valve core is matched with the valve core seat; the switch rod is rotationally matched with the switch channel. The problem is that the knob provided at the end of the switch lever is susceptible to external forces, and the switch lever rotates, causing the burner flame to become unstable. Summary of the invention [0003] The purpose of the p...
