Abstract
The utility model discloses a pressure detector connecting device, which includes a valve body (4), wherein an air vent (4.1) communicated with an air inlet of the valve body (4) is arranged on the valve body (4), the air vent (4.1) is provided with a threaded outer port (4.1.2) used for being matched with a pressure gauge connector, the air vent (4.1) is also provided with a threaded inner hole (4.1.1), a screw (5) made of stainless steel is arranged in the threaded inner hole (4.1.1), and a clearance is reserved in the threaded fit between the screw (5) and the threaded inner hole (4.1.1). The pressure detector connecting device can detect conveniently, can control the gas discharge quantity, and can eliminate potential safety hazards caused by separation of a binding nut from the valve body.
Description
Technical field
The utility model relates to the flame snuffer pressure detecting instrument coupling arrangement in the fire control equipment, especially a kind ofly is located on the fire extinguisher by-pass valve control, is used to connect manometric pressure detecting instrument coupling arrangement.
Background technology
The pressure detecting instrument coupling arrangement of prior art generally is made up of pneumatic head, binding nut, " O " RunddichtringO and gasket seal; Described pneumatic head is provided with vertical port and horizontal counterbore; Described longitudinal hole is connected with horizontal counterbore; Described horizontal counterbore collar extension can be connected with pressure detecting instrument (being tensimeter), and described binding nut is threaded with by-pass valve control, and described binding nut is against on the one side of pneumatic head convexity away from by-pass valve control.In the time need not detecting in the flame snuffer gaseous tension, binding nut is tightened (turning clockwise), and binding nut promotes the pneumatic head convexity and moves towards the by-pass valve control direction, makes the bulb of pneumatic head front end seal the air hole of by-pass valve control.In needs detect flame snuffer during gaseous tension; Tensimeter is installed in the horizontal counterbore collar extension of the pneumatic head place of pressure detecting instrument coupling arrangement; Unscrew binding nut again, this moment, pneumatic head moved away from by-pass valve control under the gaseous tension effect in fire extinguisher bottle, and the longitudinal hole that gas flows to pneumatic head in the fire extinguisher bottle from the by-pass valve control air hole is to horizontal counterbore; Flow to tensimeter via horizontal counterbore again, tensimeter shows force value; Detection finishes, and tightens (turning clockwise) binding nut, and inflation inlet front end bulb is sealed the by-pass valve control air hole, unloads tensimeter.
Because the atmosphere storage time is longer in the flame snuffer in the ordinary course of things; The situation that flame snuffer can not normally play a role when preventing to cause fire to take place because of gas leakage overshoot in the flame snuffer takes place, and needs often or regularly detect gaseous tension in the flame snuffer.And all need action that binding nut is tightened or unscrewed when detecting at every turn, and detect inconvenience, and cause the wearing and tearing of binding nut and valve body screw thread contact portion easily, cause binding nut to tighten and the uncontrollable gas amount of releasing; Also have the user when unscrewing binding nut, to unscrew the excessive binding nut that causes easily and break away from valve body; In case and binding nut breaks away from valve body; In flame snuffer, under the effect of gaseous tension, will cause pneumatic head and tensimeter outwards to eject and make the interior gas of flame snuffer spray outward, have potential safety hazard.
The utility model content
The utility model technical matters to be solved is, provide a kind of easy to detect, can the pilot-gas amount of releasing, can eliminate the pressure detecting instrument coupling arrangement of the potential safety hazard of bringing because of binding nut disengaging valve body.
The technical solution of the utility model is; A kind of pressure detecting instrument coupling arrangement with following structure is provided, comprises valve body, described valve body is provided with the blow vent that is communicated with the valve body air intake opening; Described blow vent is provided with and is used for the screw thread collar extension that cooperates with the tensimeter connector; Described blow vent also is provided with threaded interior hole, is provided with the screw that stainless steel is made in the described threaded interior hole, and there is the gap in the threaded engagement between described screw and the threaded interior hole.
After adopting above structure, the pressure detecting instrument coupling arrangement of the utility model compared with prior art has the following advantages:
The threaded interior hole of the pressure detecting instrument coupling arrangement blow vent of the utility model is provided with screw; There is the gap in threaded engagement between described screw and the threaded interior hole, and described gap forms a spiral gas passage between screw and threaded interior hole, and the gas in the flame snuffer can release out through this spiral path; When gaseous tension detects in needs carry out flame snuffer; Directly load onto tensimeter, can carry out pressure detection at the screw thread collar extension, easy to detect; Through be provided with and adjust between screw and the threaded interior hole the gap can so that the gas amount of releasing in the scope of regulation, like≤15 the bubble amount of releasing/min; Do not adopt the binding nut structure, just do not need often to turn binding nut yet, thereby can eliminate the potential safety hazard of bringing because of binding nut disengaging valve body.
As preferably, described screw is a hexagon socket cap head screw.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Shown in please seeing figures.1.and.2; The pressure detecting instrument coupling arrangement of the utility model; Comprise valve body 4; Described valve body 4 is provided with the blow vent 4.1 that is communicated with valve body 4 air intake openings, and described blow vent 4.1 is provided with and is used for the screw thread collar extension 4.1.2 that cooperates with the tensimeter connector, and described blow vent 4.1 also is provided with threaded interior hole 4.1.1; Be provided with the screw 5 that stainless steel is made in the described threaded interior hole 4.1.1, there is the gap in the threaded engagement between described screw 5 and the threaded interior hole 4.1.1.
Described screw 5 is a hexagon socket cap head screw.
In the present embodiment; Described by-pass valve control comprises the pressure cap 1 of releasing, gland 2, piston component 3 and valve body 4; Described piston component 3 is slidingly fitted in the inner chamber of valve body 4, and described gland 2 screws with valve body 4, and the described pressure cap 1 of releasing screws on gland 2.Be prior art, no longer launch to set forth here.
Hexagon socket cap head screw is screwed in the threaded interior hole 4.1.1 place of valve body 4, adjust the gas amount of releasing: like≤20 the bubble amount of releasing/min (5.7.5 that meets among the GB25977-2010 requires).When detecting, only need take off protective sleeve 6, tensimeter is installed in screw thread collar extension 4.1.2 place, tensimeter shows counting, and detecting finishes pulls down tensimeter, buckles protective sleeve 6 and gets final product.Explanation is in addition, and described protective sleeve 6 gets into blow vent 4.1 for preventing dust, is prior art; The gas amount of releasing is just adjusted through experimental test when product export, need not user oneself adjustment.
More than be the specific embodiment of the utility model, be not limited to above embodiment in actual the use, all in the structural adjustment of being done the enlightenment of the utility model under and variation all in the protection domain at the utility model.
