Abstract
A control protector for the flow control and protection of pressure gauge is composed of gauge joint wigh plug and control protector, which are integrated together. Said control protector consists of shell with damping plug and regulating rod with plug screw and sealing ring. Its advantages include high safety and reliability, complete functions including exhaustion, damping, buffering and filter, and long service life.
Description
The present invention relates to a kind of manometric protective device, particularly a kind of control protector of pressure gauge that tensimeter is directly carried out flow control and protection.The supporting use of the tensimeter that is used for measurement gas, fluid pressure with various different structures suits in industries such as boiler, machinery, chemical industry, oil, medicine.
The existing employed tensimeter great majority of every profession and trade all have only switch, and do not have the control protector.Therefore in use often because of hypertonia or cross and low tensimeter is washed out, it is inaccurate to cause tensimeter to show, needs often maintenance and transposing, causes economic loss and brings many inconvenience.
The patent No. 95232496.2 " pressure subcontrol " only provides a kind of controller of electronic type.
The object of the present invention is to provide a kind of control protector of pressure gauge, tensimeter is controlled and protected, make the tensimeter can be not impaired, prolonged manometric serviceable life greatly because of liquid, variation of gas pressure.
The present invention is achieved in that control protector of pressure gauge connects into whole institute by meter connector and control, the protective device of band plug and forms, and described control protective device for the housing of being with damping plug be connected with plug screw, be with the adjuster bar of the O-ring seal formation that matches.
Fig. 1. structural representation of the present invention
The A-A view of Fig. 2, Fig. 1
Below in conjunction with accompanying drawing embodiments of the invention are further described.
Housing (3) is a sexangle, the aperture inlet (9) that an end face has screw and communicates with it, and end face has screw to reach aperture inlet (9) and annular groove and the external thread that communicates with it in addition, the blind hole that also has screw and communicate with it on the hex surface.
Damping plug (11) is for there is aperture the centre, and periphery is the cylindrical of screw thread.Its end also is fixed with filter screen (10).
Plug screw (6) has screw, through hole for the centre, and an end is a hexagon head, and an end has externally threaded cylindrical, and a vent port (4) is arranged on the sidewall.
Meter connector (1) has screw, through hole for the centre, and the upper end is a sexangle, and the lower end is cylindrical.
Plug (2) is the middle screw rod that through hole is arranged, and also has annular groove on the end face, and spanner flat is arranged on the outer wall.
Adjuster bar (5) upper end is the screw rod of band groove, and the lower end is that the centre has blind hole, and two annular grooves are arranged on the outer wall, 4 vent ports (8) that symmetry arranged on the sidewall and communicate with middle blind hole.
Plug (2) is put into meter connector (1) and is fixed on the end face of housing (3) with screw thread; other end face of housing (3) damping plug (11) of screw thread fixed band filter screen (10); the adjuster bar (5) that has O-ring seal (7) is fixed in the plug screw (6) with screw thread; again adjuster bar (5) is put into housing (3); link into an integrated entity with plug screw (6) and housing (3), control protector of pressure gauge is assembled into.
During use, tensimeter is connected with meter connector (1), damping plug (11) termination woven hose is a duty as Fig. 1.
At this moment liquid water or the oil that enters from woven hose enters housing (3) through damping plug (11), filter screen (10) after filtering, through hole on the annular groove on the adjuster bar (5) and housing (3), plug (2) enters tensimeter again, play under the constant situation of pressure, cushion, filter, reduce the effect of flow.
If regulate the position of adjuster bar (5), it is moved up, and with the vent port (4) on the vent port on it (8) the aligning plug screw (6), at this moment adjuster bar (5) has been blocked the inlet (9) on the housing (3), liquid can not enter, and air in the tensimeter and little moisture content just the vent port (4) on the blind hole in adjuster bar (5) and vent port (8) and the plug screw (6) be discharged to outside the housing (3), play scavenging action.
If adjuster bar (5) is moved down, vent port (4), inlet (9) are all stopped up, at this moment feed liquor, yet not exhaust, tensimeter are not worked yet.
If adjuster bar (5) is moved down some distances, inlet (9) is blocked a part, flow is reduced play damping action.
The present invention is compared with prior art: because this control protector adopts frame for movement, safety, good reliability, Not affected by environment for use. Multiple functional, can adjust control, have damping, exhaust, buffering, mistake The filter effect because reduce flow in the constant situation of pressure, does not make manometric impact so can not cause Pressure gauge is impaired, has greatly prolonged manometric service life. Corrosion-resistant because of the making of employing stainless steel material, High temperature resistant. Use widely, everyly be connected to manometric place and all can install, and easy for installation, but and root According to the manometric direction of needs arbitrary decision.
Claims (3)
1. control protector of pressure gauge; connect into whole institute by the meter connector of band plug with the control protective device and form, it is characterized in that described control protective device for the housing (3) of band damping plug (11) be connected with plug screw (6), be with the adjuster bar (5) of O-ring seal (7) formation that matches.
2. protector according to claim 1, it is characterized in that housing (3) is a sexangle, the aperture inlet (9) that one end face has screw and communicates with it, end face has screw to reach aperture inlet (9) and annular groove and the external thread that communicates with it in addition, the blind hole that also has screw and communicate with it on the hex surface; Damping plug (11) is for there is aperture the centre, and periphery is the cylindrical of screw thread; Plug screw (6) has screw, through hole for the centre, and an end is a hexagon head, and an end has externally threaded cylindrical, and a vent port (4) is arranged on the sidewall; Adjuster bar (5) upper end is the screw rod of band groove, and the lower end is that the centre has blind hole, and two annular grooves are arranged on the outer wall, 4 vent ports (8) that symmetry arranged on the sidewall and communicate with middle blind hole.
3. protector according to claim 1 is characterized in that the end of damping plug (11) also is fixed with filter screen (10).
