Abstract
The utility model relates to an improvement on the existing stop valve, which comprises a valve body, a valve clack, a valve cover, a valve rod and a handle connected with the valve rod, wherein the valve cover is arranged at the upper part of the valve body and the valve rod is vertically arranged in the valve body. The lower end of the valve rod is connected with the valve clack, and the valve rod and the valve clack are both arranged in the valve body. An elastic sealing pad is arranged between the contact surface of the valve body and the valve clack. The utility model avoids the leakage problem of the stop valve and saves maintenance cost, and has the advantages of simple structure, light weight, long service life and low cost. Therefore, the valve is ensured to work reliably and efficiently.
Description
The utility model relates to a kind of valve, particularly is suitable for the pipeline stop valve of water, gas, wet goods FLUID TRANSPORTATION, is the improvement to existing stop valve.
At present, the pipeline of flowing mediums such as the transporting water that people use always, gas is valve body, flap, valve gap, valve rod and the switching handle that is attached thereto etc. with the main constituent elements of stop valve, and valve body and valve gap mostly are casting and form.Flap and valve rod are hinged, and flap can be done arbitrarily angled rotation around valve rod, do vertical elevating movement simultaneously in the valve rod rotation, thereby realize the keying of valve.Because between the valve body of above-mentioned stop valve and the flap is Spielpassung, surface of contact scratch phenomenon very easily appears, exist the dielectric leakage important disadvantages.For a long time, people can only reduce the gap in case stopping leak leaks by the machining accuracy of raising link and the wear resistance (as the copper alloy of surface of contact built-up welding between flap and valve body) of material.But caused the difficulty of processing of valve big so on the one hand, cost is high, productivity reduces, and simultaneously because its working life is lower, and the phenomenon of dielectric leakage happens occasionally, causes many inconvenience for user's use, maintenance.
The utility model purpose is to overcome above-mentioned shortcoming of the prior art and stop valve that a kind of good seal performance is provided, solves the leakage problem of valve.
The utility model purpose is achieved by the following technical solution:
Stop valve comprises valve body, flap, valve gap, valve rod and the handle that is attached thereto in forming, and valve gap places valve body top, and valve rod vertically is located in the valve body, and the lower end is connected with flap, and the two places in the valve body altogether, is provided with elastic sealing gasket between valve body and flap surface of contact.
Above-mentioned stop valve, said elastic sealing gasket are fixed on the flap end face that joins with valve body;
Above-mentioned stop valve, said elastic sealing gasket is bumped into the flap underpart, and shape and flap outer surface are complementary in it, and profile and valve body end face match.
The utility model has been avoided the leakage problem of stop valve, has saved maintenance expenses, and has simple in structure, in light weight, long service life, advantage that cost is low, thereby guarantees that stop valve reliably, work effectively.
Fig. 1 is the utility model embodiment's a vertical section structure schematic representation.
Fig. 2 is the vertical section structure schematic representation of the utility model embodiment flap.
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment:
Referring to Fig. 1, the utility model comprises valve body 1, flap 2, valve gap 3, valve rod 4 and coupled handle 5 in forming, and valve gap 3 places valve body 1 top, and valve rod 4 vertically is located in the valve body 1, its lower end and flap 2 are hinged, and promptly flap can be done arbitrarily angled rotation around valve rod.Key improvements part of the present utility model is to be provided with elastic sealing gasket 6 between valve body 1 and flap 2 surface of contact.
Referring to Fig. 1,2, the interior shape of elastic sealing gasket 6 and flap 2 outer surfaces are complementary, and profile and valve body 1 end face match.It can be adhesively fixed on flap 2 end faces that join with valve body 1, also it can be bumped into flap 2 underparts.
The selected elastic sealing gasket 6 of the utility model is Applicable temperature-20 ℃-200 ℃, is suitable for pressure≤1.6MPa, and ageing-resistant, corrosion resistant rubber product makes that no gap cooperates between valve body and the flap, has avoided the dielectric leakage phenomenon.
The utility model can be made into structure and boundary dimension and meet the flange connection cast iron stop valve of specific criteria requirement or the cast iron stop valve that is threaded, also can be designed to the stop valve of different profiles and size according to different installation requirements.
