The utility model discloses following beneficial effect has: increase a lock -nut on the valve rod, the position of fixed valve rod that can be accurate, the size in accurate control through flow opening gap.
Description
Technical field
The utility model relates to machinery and manufactures processing technique field, particularly a kind of manually operated valve of one.
Background technique
A kind of manually operated valve is controlling component in pipeline fluid transporting system, and it is used to change path section and media flow direction, has the functions such as water conservancy diversion, cut-off, adjustment, throttling, non-return, shunting or overflow release.For a kind of manually operated valve that fluid controls, a kind of inside nominal diameter of manually operated valve reaches greatly the industrial pipeline valve of 10m to latus rectum from atomic little Gauge Valves.A kind of manually operated valve can under the effect of pressure, temperature or other form transducing signal, by pre-provisioning request action, or do not rely on transducing signal and simply open or close, a kind of manually operated valve rely on drive or automechanism makes open-shut device be elevated, slippage, swing or rotation motion, thus the size changing its Flow area is to realize its controlling functions.
After existing a kind of manually operated valve often easily appears at and regulates feed flow size, under the effect of fluid pressure, original flow gap can become large, causes the water-outlet quantity at one time to increase, very unstable.
Summary of the invention
For deficiency of the prior art, the utility model provides a kind of manually operated valve, solves above-mentioned problem.
The utility model is achieved through the following technical solutions.
A kind of manually operated valve, comprise valve body, described valve body comprises water intake and water outlet, described valve body is made up of two cavitys, what coordinate with water outlet is the first cavity, what coordinate with water intake is the second cavity, the liquid size of water outlet is controlled by the movable push bar assembly above it by the through flow hole on valve body, elastic sealing gasket is added above the plunger of described movable push bar assembly bottom, the diameter of described elastic sealing gasket is greater than the aperture of through flow hole, described movable push bar assembly is provided with the lock-nut of a restriction valve rod upper-lower position.
Lock-nut can after adjusting nut regulates, and the effective position controlling valve rod, prevents water velocity more and more faster.
As preferably, it is inner that described movable push bar assembly is arranged at plastic mounting seat, and the Placement that described plastic mounting seat adopts internal and external threads to be combined between valve body, has not only saved cost of material, and quick and easy for installation, raising installation efficiency.
As preferably, described movable push bar assembly comprises the plunger of bottommost, is provided with elastic sealing gasket above described plunger, is provided with the valve rod coordinated with plastic mounting seat above described elastic sealing gasket, movable push bar assembly can be manual the gap size of adjustment through flow hole, control flow.
As preferably, the bottom of described valve body internal thread is provided with seal ring A, ensure that sealing, reduces rigid impact during screwed tight.
As preferably, described valve rod is used for laying multiple seal ring B with multiple notch, and described valve stem end is provided with adjusting nut, and adjusting nut can adopt the position of tightening the mode regulating valve stem unscrewed.
As preferably, described water intake and water outlet are all provided with the rapid pipe joint for connecting water pipe.
Compared with prior art: on valve rod, increase a lock-nut, the position of valve rod can be fixed accurately, the accurate size controlling through flow hole gap.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side view of the present utility model.
Fig. 3 is plan view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further.
A kind of manually operated valve, comprise valve body 1, described valve body 1 comprises water intake 12 and water outlet 13, described valve body 1 is made up of two cavitys, what coordinate with water outlet 13 is the first cavity 2, what coordinate with water intake 12 is the second cavity 3, the liquid size of water outlet 13 is controlled by the movable push bar assembly above it by the through flow hole 4 on valve body 1, elastic sealing gasket 7 is added above the plunger 6 of described movable push bar assembly bottom, the diameter of described elastic sealing gasket 7 is greater than the aperture of through flow hole 4, described movable push bar assembly is provided with the lock-nut 10 of restriction valve rod 9 upper-lower position, it is inner that described movable push bar assembly is arranged at plastic mounting seat 15, the Placement that described plastic mounting seat 15 adopts internal and external threads to be combined between valve body 1, described movable push bar assembly comprises the plunger 6 of bottommost, above described plunger 6, elastic sealing gasket 7 is installed, the valve rod 9 coordinated with plastic mounting seat 15 is installed above described elastic sealing gasket 7, the bottom of described valve body 1 internal thread is provided with seal ring A5, described valve rod 9 is used for laying multiple seal ring B8 with multiple notch, described valve rod 9 end is provided with adjusting nut 11, described water intake 12 and water outlet 13 are all provided with the rapid pipe joint 111 for connecting water pipe.
When wanting a kind of manually operated valve to open, hold adjusting nut 11 and carry out manual tune, after being adjusted to the current size oneself wanted, what lock-nut 10 was screwed to plastic mounting seat 15 is close to face, fix the position of valve rod 9, prevent from making because current are excessive valve rod 9 move.
Now current will flow in the gap between plastic mounting seat 15 and valve rod 9 from the second cavity 3, make upper and lower hydraulic balance, current can flow in the first cavity 2 in through flow hole 4, then discharge from water outlet 13, and seal ring A5 and seal ring B8 ensure that the sealing of whole device simultaneously.
When a kind of manually operated valve cuts out, need to tighten adjusting nut 11 to arrive bottom, sealing in the past adopts frustoconic shape plunger 6, blocking through flow hole 4 carrys out Leakage prevention, the passing in this mode transit time, the gap between the endoporus of through flow hole and plunger 6 can be caused increasing, cause leaking, under the effect of elastic sealing gasket 7, can effective Leakage prevention, and flow can be controlled accurately when a kind of manually operated valve is opened.
Protection domain of the present utility model includes but not limited to above mode of execution; protection domain of the present utility model is as the criterion with claims, and any replacement that those skilled in the art will find apparent that, distortion, improvement made this technology all falls into protection domain of the present utility model.
