Description
Technical field
The utility model belongs to Leibo pump feather valve fittings equipment technical field, and in particular to a kind of Leibo pump hand unloads valve.
Background technique
Leibo pump feather valve can ensure that output fluid pressure is set pressure when system (pump) works, specific to press
Power size by connection pressure gauge real-time monitoring monitoring, while when make pump work by connecting shut-off valve with the external world every
From guarantee pressure is set pressure, and after pump is out of service, (such as maintenance, inspection etc.) carries out pressure release to pump if needed, is let out
Fall overbottom pressure to ensure work safety.The mode generallyd use in the prior art when connecting pressure gauge and shut-off valve on feather valve
It is to take source block i.e. hand to unload valve by connecting on feather valve, later again in threeway after the other end that hand unloads valve installs threeway additional
Other both ends pressure gauge and shut-off valve are installed respectively, still, the problem of such mode causes is exactly to install pressure gauge and cut
Only when valve, because the point of application unloads valve fixing bolt farther out apart from hand, the arm of force is long, and stress is big, is easily damaged the close of mounting part
Envelope, when have leakage situation.
Utility model content
The purpose of this utility model is to provide a kind of Leibo pump hands to unload valve, solve existing feather valve installation pressure gauge and
The problem of stress difference causes mounting part easy to damage to seal when shut-off valve.
The technical scheme adopted by the utility model is a kind of Leibo pump hand unloads valve, including cuboidal valve body, on valve body
Centre bore up and down is offered, the fixing bolt that both ends are located at outside valve body is equipped in centre bore, fixing bolt
The first deflector hole is radially offered on screw rod, is provided in the axial direction on the screw rod of fixing bolt far from head one end and is led with first
Second deflector hole of discharge orifice connection, the two sides of valve body offer the pressure gauge intercommunicating pore and cut-off coaxial with the first deflector hole respectively
Valve intercommunicating pore.
The utility model is also characterized by
The upper and lower ends of valve body offer annular seal groove along the circumferential direction of centre bore.
Seal washer is provided in seal groove.
The two sides of valve body offer U-shaped card mounting hole up and down.
The inner diameter size of first deflector hole and the second deflector hole is suitable.
The beneficial effects of the utility model are: a kind of Leibo pump hand of the utility model unloads valve, by installation pressure gauge and cut-off
The hole of valve is designed as coaxial, integral type, orthogonal with fixing bolt axle center and be distributed in valve body both ends, the peace apart from fixing bolt
It is closer to fill fixed position, with respect to fixing bolt axle center without torque when installing pressure gauge and shut-off valve, stress is small and uniform, and structure is tight
It gathers, it is convenient for disassembly and assembly, it is not easy to leak.

Specific embodiment
With reference to the accompanying drawing and the utility model is described in detail in specific embodiment.
The utility model provides a kind of Leibo pump hand and unloads valve, as shown in Figures 1 to 4, including cuboidal valve body 1, valve
Centre bore 2 up and down is offered on body 1, the upper and lower ends of valve body 1 offer annular seal groove along the circumferential direction of centre bore 2
8, seal washer 9 is provided in seal groove 8, and the fixing bolt 3 that both ends are located at outside valve body 1 is equipped in centre bore 2, Gu
Determine radially to offer the first deflector hole 4 on the screw rod of bolt 3, be opened far from head one end along axial direction on the screw rod of fixing bolt 3
Equipped with the second deflector hole 5 being connected to the first deflector hole 4, the inner diameter size of the first deflector hole 4 and the second deflector hole 5 is suitable, valve
The two sides of body 1 offer the pressure gauge intercommunicating pore 6 and shut-off valve intercommunicating pore 7 coaxial with the first deflector hole 4 respectively, and the two of valve body 1
Side is also provided with U-shaped card mounting hole 10 up and down.
In use, being fixed on valve body 1 on feather valve the screw-in pump housing feather valve interface of fixing bolt 3, at this point, first leads
4 both ends of discharge orifice are connected to pressure gauge intercommunicating pore 6 and shut-off valve intercommunicating pore 7 respectively, the second water conservancy diversion being also connected to the first deflector hole 4
Hole 5 connects pressure gauge and shut-off valve to connect feather valve on pressure gauge intercommunicating pore 6 and shut-off valve intercommunicating pore 7 respectively later,
Seal washer 9 in 1 upper and lower ends seal groove 8 of valve body can be sealed when fixing bolt 3 fastens, and prevent fluid from centre bore
2 both ends leakage, can be in the pressure gauge and shut-off valve intercommunicating pore 7 connected in pressure gauge intercommunicating pore 6 by U-shaped card mounting hole 10
The shut-off valve of connection is attached, fixes.
By the above-mentioned means, a kind of Leibo pump hand of the utility model unloads valve, the hole for installing pressure gauge and shut-off valve is designed
For coaxial, integral type, it is orthogonal with 3 axle center of fixing bolt and be distributed in 1 both ends of valve body, the installation apart from fixing bolt 3 is fixed
Position is closer, and with respect to 3 axle center of fixing bolt without torque when installing pressure gauge and shut-off valve, stress is small and uniform, compact-sized, tears open
Dress is convenient, is not easy to leak.Through tentatively on probation, this hand unloads valve can be with good connection between pump housing feather valve, ne-leakage liquid phenomenon, can
It is produced and used with small lot.
