Abstract
The utility model discloses an improvement structure of outdoor pressure regulating fire hydrant, which includes a hydrant body, a valve body, an elbow, a valve rod, a valve rod nut, a locking female connector, a valve clack, a pressure relief cap and a valve clack sealing pad. The bottom surface of the valve clack is connected with the pressure relief cap; the valve clack sealing pad is arranged between the valve clack and the pressure relief cap; the pressure relief cap can be rotatably sleeved in the hole of a valve base; the valve base is arranged on a water inlet channel at the lower part of the inner cavity of the valve body. As one pressure relief cap is additionally arranged at the bottom part of the valve clack, the pressure relief cap can modulate the rated water inlet pressure to effectively control the water outlet pressure through the cooperation of the pressure relief cap and the valve base simultaneously when opening a water flow, to play the role of modulating pressure, thereby reaching rated water inlet pressure and rated water outlet pressure and having good pressure regulating effect.
Description
Technical field
The utility model relates to a kind of fire-fighting equipment, particularly relates to a kind of improvement structure of outdoor voltage-regulation type hydrant.
Background technology
The outdoor fire hydrant of commonly using is directly to connect flap by valve rod, comes switch hydraulic pressure by valve rod again.The hydrant of this structure, the pressure of water can not reach the force value of the needed water of rescue personnel, can not effectively control hydraulic pressure, can't satisfy rescue personnel's needs.
The utility model content
The purpose of this utility model is to provide a kind of improvement structure that can better regulate the outdoor voltage-regulation type hydrant of hydraulic pressure.
For achieving the above object, technical solution of the present utility model is:
The utility model is a kind of improvement structure of outdoor voltage-regulation type hydrant, and it comprises key, valve body, elbow, valve rod, valve stem nut, anti-reducing sleeve, flap; The lower end of described key connects the valve body upper end, the lower end connecting bend of valve body, and the key that links together, valve body and elbow inner chamber constitute a water stream channel; Described valve stem nut is fixed on the key inwall by anti-reducing sleeve, and described valve rod top is screwed onto on the valve stem nut, and its lower end is connected the flap upper end; It also comprises decompression cap and a flap sealing mat, and the bottom surface of described flap connects the decompression cap, and the flap sealing mat is installed between flap and the decompression cap, reduces pressure that cap is rotating to be nested with in the valve base hole, and valve base is installed on the bottom intake tunnel of body cavity.
After adopting such scheme, because the utility model increases a decompression cap in the flap bottom, this decompression cap is when opening current, cooperate with valve base by the decompression cap, can modulate specified water inlet pressure and effectively control delivery port pressure, play the effect of pressure regulation, thereby reach the water inlet pressure of regulation and specified delivery port pressure, voltage regulation result is good.
Below in conjunction with the drawings and specific embodiments the utility model is further described.
Description of drawings
Fig. 1 is an outline drawing of the present utility model;
Fig. 2 is a sectional view of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model is a kind of improvement structure of outdoor voltage-regulation type hydrant, and it comprises key 1, valve body 2, elbow 3, valve rod 4, valve stem nut 5, anti-reducing sleeve 6, flap 7, decompression cap 8, valve base 9 and flap sealing mat 10.
The lower end of described key 1 connects valve body 2 upper ends, the lower end connecting bend 3 of valve body 2, and the inner chamber of the key 1 that links together, valve body 2 and elbow 3 constitutes a water stream channel.
Described valve stem nut 5 is fixed on key 2 inwalls by anti-reducing sleeve 6, and described valve rod 4 tops are screwed onto on the valve stem nut 5, and its lower end is connected flap 7 upper ends.Valve rod 4 is that fulcrum rotates with valve stem nut 5, drives the lifting of flap 7.
The bottom surface of described flap 7 connects decompression cap 8, and flap sealing mat 10 is installed between flap 7 and the decompression cap 8, decompression cap 8 rotating being nested with in valve base 9 holes, and valve base 9 is installed on the bottom intake tunnel of valve body 2 inner chambers.
Emphasis of the present invention just is: increase a decompression cap in the flap bottom.
The above, it only is the utility model preferred embodiment, so can not limit the scope that the utility model is implemented with this, i.e. the equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
