Abstract
The utility model discloses a novel overflow valve, which comprises a valve body, a valve cover, a valve and a screw. The novel overflow valve is characterized in that an inlet and an outlet are formed on the two sides of the valve body, the outlet is higher than the inlet, the T-type valve is arranged at the turning part of the outlet and the inlet, the valve is connected with a spring body through the screw and arranged in the cavity formed by the valve cover and the valve body, the screw passes through the top end of the valve cover, the upper part of the screw is tightened through a nut, an encasing outside the screw is fixed on the valve cover, small round holes are formed on the two sides of the valve, a screw hole is formed at the bottom of the inner cavity of the valve, the valve body and the valve cover are connected through a stud, a spacer is arranged in the middle thereof. The utility model has the advantages that the structure is simple; the disassembly is easy; the maintenance and installation are convenient; the air tightness is excellent due to adoption of the spacer structure; and the pressure stabilizing function is strong.
Description
Technical field
The utility model belongs to a kind of valve, specifically is a kind of relief valve.
Background technique
Relief valve is the normally closed outlet port that is installed in oil hydraulic pump in the hydraulic system, its effect is keep system pressure stable, will open and be switched to fuel tank when pressure surpasses pressure (elastic force of spring just) that he sets, at this moment the oil that comes from oil hydraulic pump flows to fuel tank with regard to some from relief valve, so just can keep the pressure of hydraulic system.At present, the oil pressure relief instability causes the oil cylinder job insecurity when employing ball valve that the relief valve that uses in the hydraulic system has, this valve working, and the assembling more complicated.The employing conical valve that has, this valve seal is not so good, influences voltage regulation result.
The model utility content
The purpose of this utility model provides a kind of novel relief valve, and overall structure is simple, and is quick detachable, easy maintenance and installation, and good airproof performance, voltage stabilizing function is strong.
The technical solution of the utility model is as follows:
Novel relief valve, include valve body, valve gap, valve, screw rod, it is characterized in that there are import and outlet in described valve body both sides, and the exit position is higher than import, import has valve with the outlet turning point, valve is the T type, valve is connected by spring body with screw rod, and is positioned at the cavity of valve gap and valve body formation, and screw rod passes the valve gap top, screw rod top is also tight with nut, screw rod has cover to be fixed on the valve gap outward, and there is small sircle hole the valve both sides, and the intracavity bottom of valve has screw, valve body adopts double-screw bolt to be connected with valve gap, and there is pad the centre.
The utility model overall structure is simple, interact the switch of control valve by oil pressure in the pressure of spring and the conduit, voltage stabilizing function is strong, can effectively guarantee the safety of pipeline, nut is set on screw rod top can prevents that screw rod is loosening, the valve both sides are provided with small sircle hole, and the oil that enters body cavity is flowed out, and reach the effect of oil sealing simultaneously, the intracavity bottom of valve has screw, be convenient to install, dismantle and maintenance, adopt gasket construction, good airproof performance.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Novel relief valve, include valve body 1, valve gap 2, valve 3, screw rod 4, it is characterized in that there are import 5 and outlet 6 in described valve body 1 both sides, and export 6 positions and be higher than import 5, import 5 has valve 3 with outlet 6 turning points, valve 3 is the T type, valve 3 is connected by spring body 7 with screw rod 4, and is positioned at the cavity of valve gap 2 and valve body 1 formation, and screw rod 4 passes valve gap 2 tops, screw rod 4 tops are also tight with nut 8, have cover 9 to be fixed on the valve gap 5 outside the screw rod 4, there is small sircle hole 10 valve 3 both sides, and the intracavity bottom of valve 3 has screw 11, valve body 1 adopts double-screw bolt 12 to be connected with valve gap 2, and there is pad 13 centre.
The utility model mainly is to use on the oil feed line; when proper functioning; valve 3 is in closed position by the pressure of spring body 7; this moment, oil flowed into inlet ductwork from valve body import 5; when oil pressure in the inlet ductwork increases above spring body 7 pressure; valve 3 is backed down; oil just flows back to fuel tank along the outlet conduit of valve outlet 6, and to guarantee the safety of pipeline, the size of spring body 7 pressure is regulated by screw rod 4; loosening for preventing screw rod 4; with nut 8 and tight, cover 9 is used for protecting screw rod 4, the small sircle hole 10 of valve 3 both sides on screw rod 4 tops; the oil that enters valve body 1 inner chamber is flowed out, and the pad 13 in the middle of valve body 1 and the valve gap 2 can prevent leakage of oil.
Claims (1)
1. novel relief valve, include valve body, valve gap, valve, screw rod, it is characterized in that there are import and outlet in described valve body both sides, and the exit position is higher than import, import has valve with the outlet turning point, valve is the T type, valve is connected by spring body with screw rod, and is positioned at the cavity of valve gap and valve body formation, and screw rod passes the valve gap top, screw rod top is also tight with nut, screw rod has cover to be fixed on the valve gap outward, and there is small sircle hole the valve both sides, and the intracavity bottom of valve has screw, valve body adopts double-screw bolt to be connected with valve gap, and there is pad the centre.
