Abstract
A detectable gas-leaking valve includes a switch valve and a security detection device connected with the switch valve. The switch valve consists of an inner valve tuck of the valve body on which a valve shaft is provided and a handle is arranged on the valve shaft. An air escape pipe is provided on the switch valve. The security detection device is composed of a pressure gauge base arranged between the switch valve and the air escape pipe and a pressure indicator arranged above the pressure gauge. The indicator can be a gas sensor or a pressure-sensitive sensor, etc. The utility model is characterized in that the structure is simple, the layout is reasonable and the gas-leaking detection device and pressure gauge can sensitively detect the leaking of the cookers, the pipes and the air escape pipe. In addition, the general structure is simple, the operation is easy, and the cost is low.
Description
Technical field
The utility model relates to a kind of gas valve, particularly relate to a kind of structure improved can detection of leaks, the higher gas valve of Security, be applicable to the family that uses coal gas to make fuel.
Background technique
At present, coal gas acts as a fuel, huge numbers of families have been deep into, big and medium-sized cities particularly, piped gas has been installed to the kitchen, wherein gas valve is a very important components, patent retrieval is found, someone has applied for the patent of " gas switch safety valve " (99208707.4) by name, it discloses a kind of safety valve that is used for gas pipe, form by valve seat, valve pocket, valve plug, pressure spring, steel ball, thermometal sheet etc., and adopted the unusual gas flow of mat to act on pressure spring to make the self-acting valve of valve sealing improve its Security.Its deficiency is that the starting point has been placed on the Security that seal for pipe joints influenced, and has ignored the kitchen range sealability to Influence on security.
Summary of the invention
The utility model mainly is to solve existing in prior technology can not detect the technical problem of sealability such as kitchen range to Influence on security etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: comprise switch valve and coupled safety detection device, wherein said switching valve train is by being arranged in the valve body valve plug and which is provided with valve shaft, and the handle of being located on the valve shaft forms, and switch valve is provided with steam outlet pipe; Described safety detection device system forms by being arranged on pressure gauge stand between switch valve and the described steam outlet pipe and pressure indicator provided thereon, and described indicator can be a gas sensing member, or voltage sensitive sensor etc.
As preferably, described pressure indicator is a pressure gauge; And on described pressure gauge stand, be provided with the axis of guide and be placed on the Returnning spring and the button thereof of one end; Two ends and axis of guide joint at described pressure gauge stand are provided with seal ring.The working pressure table makes overall structure further simplify.
As preferably, be provided with one section slit between the middle part of the described pressure gauge stand and the axis of guide, and one side and the communication of described pressure epiphase.Because the slit total space volume of the pressure gauge and the axis of guide is less, the moment of button down gets final product pipeline pressure balance substantially; If follow-up pipeline has leakage slightly, can from pressure gauge, be shown sensitively.
As preferably, the underpart of the described axis of guide is provided with boss, between described boss and the pressure gauge stand seal ring is set; Described Returnning spring underpart is provided with spring seat, between itself and the described pressure gauge stand seal ring is set also.
As preferably, the lower end of the described axis of guide is provided with disk body, and its underpart is provided with groove, and the groove internal fixation has seal ring; And in described valve body, be provided with one with the cavity of described disk body phase configuration, the bottom of cavity is an air vent.
Therefore, the utlity model has simple in structurely, rationally distributed, gas leak detection device is set, pressure gauge can detect the characteristics such as leakage of kitchen range, pipeline and steam outlet pipe sensitively, and in addition, overall structure is simple, and is easy and simple to handle, with low cost.
